Description

Water treatment machine and control valve for water treatment machine

Technical Field

The present utility model relates to a water treatment machine, and more particularly, to a water treatment machine capable of performing multistage treatment on raw water (e.g., tap water) to obtain treated water having a desired water quality. The utility model further relates to a control valve for a water treatment machine.

Background

In modern industrial production, many industries require water of high cleanliness or low hardness. However, many countries, particularly developing countries, are not able to meet industrial water standards for cleanliness and hardness, whether they be surface or underground water sources. In order to obtain water of a desired quality, it is necessary to treat water (or raw water) from a water source. Raw water is treated by coarse filtration, which is to filter out larger particle contaminants to obtain coarse-filtered water, then further filtering the coarse-filtered water by using activated carbon and other materials to obtain cleaner purified water, and finally softening (or ultrafiltration or RO membrane filtration) the obtained purified water to obtain softened water (or purified water with extremely high purity). Finally, the raw water is subjected to multi-stage treatment (three-stage or more treatment) to obtain treated water having a desired water quality. For example, people use a water filtration device (the filter material is quartz sand, activated carbon or PP cotton filter material, etc.) and a water ultrafiltration device (the filter material is ultrafiltration membrane wire generally) to filter and ultrafilter raw water in sequence; or the raw water is filtered, ultrafiltered and RO membrane treated by utilizing water filtering equipment, water ultrafiltering equipment and RO membrane water purifying equipment in sequence; or the pre-filter, the water filtering equipment and the water softener are utilized to sequentially carry out coarse filtration, filtration and softening treatment on the raw water. In addition, with the increasing enhancement of the living standard and the increasing importance of health, the quality requirements of people on living water are also higher. The treatment of water retrieved from the source is relatively extensive in waterworks and insufficient to remove all impurities, such as particulate contaminants (floc gels, silt, even bacteria, etc.), and it is increasingly difficult to meet the needs of people. In addition, the aging of the tap water supply pipe network can bring new pollution to tap water. Therefore, in order to further purify tap water and improve the cleanliness thereof, various water treatment means are also required to treat tap water.

However, most of the existing water treatment systems or water treatment apparatuses capable of performing multistage treatment on raw water include a plurality of water treatment devices and a plurality of control valves for controlling water to flow inside the respective water treatment devices, respectively, because each water treatment device has a corresponding control valve, each control valve controls the water treatment function and the flushing function of the respective water treatment device, respectively, and thus the plurality of control valves are connected in series. The multiple control valves of the water treatment system lead to high manufacturing cost and large occupied space, and meanwhile, the multiple control valves cause higher failure rate of the whole water treatment system because the control valves are more complex devices. The utility model patent application No. CN202022865712.3 discloses a water treatment system which is provided with three filtering tanks connected in series, controls the flow direction of water and performs three-stage treatment on the water through a single control valve, and solves the problem of excessive control valve number of the water treatment system. However, the water treatment system disclosed in the patent is very simple in structure, and although it is capable of performing multistage treatment on raw water using three filter tanks connected in series, it is impossible to perform back flushing or forward flushing on the filter tanks separately and individually. The structure of the water treatment system disclosed in the patent means that when three filter tanks connected in series are subjected to forward flushing, sewage generated by forward flushing of a first filter tank flows into a second filter tank, sewage generated by forward flushing of the second filter tank flows into a third filter tank, and when three filter tanks connected in series are subjected to reverse flushing, sewage generated by reverse flushing of the third filter tank flows into the second filter tank, and sewage generated by reverse flushing of the second filter tank flows into the first filter tank. In other words, when three filter media tanks connected in series are positively rinsed, only the first filter media tank may be cleaned, while the second filter media tank and the third filter media tank may not be cleaned, but may be further contaminated; when three filter media tanks connected in series are backwashed, only the third filter media tank may be cleaned, while the second filter media tank and the first filter media tank may not be cleaned, but may be further contaminated. In particular, the cleaning effect of forward flushing and backward flushing three filter material tanks connected in series of the water treatment system may be worse in consideration of the stepped reduction effect of the three filter material tanks connected in series on the raw water pressure.

The existing water treatment machine has the defect of function, and brings certain inconvenience to users.

More preferably, when the control valve 10 of the water treatment machine of the present utility model is controlled to be in the third forward washing operation position, the flow of water in the first opening 1101, the second opening 1102, the third opening 1103 and the fourth opening 1104 is blocked, so that the flow of water in the first water treatment device 51 and the second water treatment device 52 is blocked. More specifically, when the control valve 10 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the third positive washing operation position, water cannot flow from the first opening 1101 or the second opening 1102 of the valve body 11 to the first water treatment device 51; water cannot flow from the third opening 1103 or the fourth opening 1104 of the valve body 11 to the second water treatment device 52, thereby ensuring that raw water can flush the third water treatment device 53 only in a forward direction. It will be appreciated that when the control valve 10 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the third positive flushing operation, the water treatment machine of the present utility model is controlled to be in its third positive flushing operation.

It is noted that when the planar valve 10 is in the water treatment position, the ninth channel 109 is in communication with the second channel 102 and the third channel 103, respectively, because the first opening 1101 is in communication with the first water inlet 511 of the first water treatment device 51, the tenth channel 1010 is in communication with the sixth channel 106 and the seventh channel 107, respectively, the eleventh channel 1011 is in communication with the second water inlet 521 of the second water treatment device 52, respectively, i.e., when the planar valve 10 is in the water treatment position, the second opening 1102 and the third opening 1103 are in communication with the second water treatment channel 7002, the fourth opening 1104 and the fifth opening 1105 are in communication with the first water inlet 511 of the first water treatment device 51, the second opening 1102 is in communication with the first water outlet 512 of the first water treatment device 51, the third opening 1104 is in communication with the second water inlet 521 of the second water treatment device 52, the fourth opening 1104 is in communication with the second water outlet 521 of the second water treatment device 52, the third opening 1105 is in communication with the third water inlet 53 of the third water treatment device 53, the third water treatment device 53 is in communication with the third water treatment device 53, the first water treatment device 53 is in series, and the third water treatment device 53 is in communication with the third water inlet 53, purified treated water flows out of the first fluid opening 1107 and is provided.

As shown in fig. 11A to 11C and 12A of the drawings, illustratively, when the plane valve 10 of the water treatment machine according to the embodiment of the present utility model is controlled to be at the water treatment working position, raw water from the plane valve 10 flows into the valve cavity 110 from the second fluid opening 1108 of the valve body 11 under the action of water pressure, flows into the first opening 1101 through the eighth passage 108 and the first passage 101, flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51, is treated (e.g., purified or softened) by the first water treatment material 515 under the action of water pressure, and the generated primary treatment water is collected by the first central tube 514 and flows out from the first water outlet 512 of the first water treatment device 51; under the action of water pressure, the primary treatment water further flows to the second water inlet 521 of the second water treatment device 52 and flows into the second water treatment device 52 through the second opening 1102, the second channel 102, the ninth channel 109, the third channel 103 and the third opening 1103 of the plane valve 10, and under the action of water pressure, after being treated (e.g. purified or softened) by the second water treatment material 525, the generated secondary treatment water is collected by the second central pipe 524 and flows out from the second water outlet 522 of the second water treatment device 52; secondary treated water further flows through the fourth opening 1104, the fourth passage 104, the tenth passage 1010, the fifth passage 105, the fifth opening 1105 of the planar valve 10 to the third water inlet 531 of the third water treatment device 53 and into the third water treatment device 53 under the water pressure, and after being treated (e.g., purified or softened) by the third water treatment material 535 under the water pressure, the generated tertiary treated water is collected by the third center pipe 534 and flows out of the third water outlet 532 of the third water treatment device 53 and toward the sixth opening 1106 of the valve body 11 of the planar valve 10, and is then supplied through the sixth passage 106, the eleventh passage 1011, the seventh passage 107 and the first fluid opening 1107 of the planar valve 10.

As shown in fig. 10B, 11D and 12B of the drawings, the planar valve 10 of the water treatment machine according to the embodiment of the present utility model further has a first backwash operation position in which the eighth passage 108 of the planar valve 10 communicates with the second passage 102 when the planar valve 10 is in the first backwash operation position, thereby forming the first backwash flow channel 7101 communicating with the second fluid opening 1108 and the second opening 1102 of the valve body 11 of the planar valve 10, respectively, and the twelfth passage 1012 communicates with the first passage 101, thereby forming the second backwash flow channel 7102 communicating with the drain opening 11012 and the first opening 1101 of the valve body 11 of the planar valve 10, respectively. As shown in fig. 7A to 7F, 10B and 12B of the drawings, further, when the plane valve 10 is in the first backwash operation position, the ninth passage 109 is communicated with the fourth passage 104 and the fifth passage 105, respectively, the tenth passage 1010 is communicated with the fifth passage 105, the eleventh passage 1011 is communicated with the first passage 101, and the third passage 103 and the sixth passage 106 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively. Thus, although the ninth passage 109 communicates with the fourth passage 104 and the fifth passage 105, respectively, the tenth passage 1010 communicates with the fifth passage 105, and the eleventh passage 1011 communicates with the first passage 101, since the third passage 103 and the sixth passage 106 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, and the ninth passage 109, the tenth passage 1010 and the eleventh passage 1011 are blind through-holes, so that raw water can only flow into the eighth passage 108 from the second fluid opening 1108 of the plane valve 10, and further flow into the first water outlet 512 of the first water treatment device 51 and into the first water treatment device 51 via the second passage 102, the second opening 1102, the waste water generated by back flushing the first water treatment device 51 flows from the first water inlet 511 of the first water treatment device 51 to the first opening 1101 of the plane valve 10, and is further discharged via the first passage 101, the twelfth passage 1012 and the drain opening 11012 of the plane valve 10 under the water pressure. In other words, although the ninth passage 109 communicates with the fourth passage 104 and the fifth passage 105, the tenth passage 1010 communicates with the fifth passage 105, and the eleventh passage 1011 communicates with the first passage 101, respectively, water does not flow through the flow passages formed by them. Accordingly, when the planar valve 10 is in the first backwash operation position, the third passage 103 and the sixth passage 106 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, thereby blocking water flow through the third opening 1103 and the sixth opening 1106 of the planar valve 10; although the ninth passage 109 communicates with the fourth passage 104 and the fifth passage 105, respectively, the ninth passage 109 is a blind via, and therefore, water flow is prevented from flowing through the fourth opening 1104 and the fifth opening 1105 of the planar valve 10, thereby preventing water flow in the second water treatment apparatus 52 and the third water treatment apparatus 53. In other words, although the ninth passage 109 communicates with the fourth passage 104 and the fifth passage 105, respectively, the third passage 103, the third opening 1103, the second water treatment device 52, the fourth opening 1104, the fourth passage 104, the ninth passage 109, the fifth passage 105, the fifth opening 1105 and the third water treatment device 53 of the plane valve 10 are communicated in sequence and the second water treatment device 52 and the third water treatment device 53 are connected in series, since the movable valve plate 122 blocks the flow of raw water to the third passage 103, the fourth passage 104, the fifth passage 105 and the sixth passage 106, thereby ensuring that only the first water treatment device 51 is backwashed. Preferably, the twelfth channel 1012 is a through hole, and the twelfth channel 1012 forms the drain opening 11012.

It is noted that when the planar valve 10 is in the first backwash operation position, the third channel 103 and the sixth channel 106 are blocked by the movable valve plate 122, respectively, such that the third opening 1103 and the sixth opening 1106 are blocked, and even though the ninth channel 109 is in communication with the fourth channel 104 and the fifth channel 105, respectively, such that the fourth opening 1104 and the fifth opening 1105 are in communication, no water flow in the fourth opening 1104 and the fifth opening 1105, that is, the second water treatment device 52 and the third water treatment device 53 are connected in series through the fourth opening 1104 and the fifth opening 1105, while the third opening 1103 and the sixth opening 1106 are blocked by the movable valve plate 122, such that the second water treatment device 52 and the third water treatment device 53 are isolated from the water flow, to ensure that only the first water treatment device 51 is backwashed, thereby preventing the generated sewage from flowing to the second water treatment device 52 and the third water treatment device 53 while increasing the strength of the water flow of the first water treatment device 51. Thus, the first water treatment device 51 of the water treatment machine of the present utility model is independently backwashed when the planar valve 10 is in the first backwash operating position.

As shown in fig. 11C, 11D and 12B of the drawings, illustratively, when the plane valve 10 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the first backwash operation position, raw water from the plane valve 10 flows into the first water treatment device 51 from the first water outlet 512 of the first water treatment device 51 under the action of water pressure, then flows from the first central pipe 514 to the first water treatment material 515 and backflushes the first water treatment material 515 under the action of water pressure, and generated sewage flows out from the first water inlet 511 of the first water treatment device 51 and flows to the first opening 1101 of the plane valve 10 under the action of water pressure, then flows to the sewage drain opening 11012 and is discharged through the second backwash flow passage 7102.

As shown in fig. 10C, 11E and 12C of the drawings, the planar valve 10 of the water treatment machine according to the embodiment of the present utility model further has a second backwash operation position in which the eighth passage 108 of the planar valve 10 communicates with the fourth passage 104 when the planar valve 10 is in the second backwash operation position to form the third backwash flow passage 7103 communicating with the second fluid opening 1108 and the fourth opening 1104 of the valve body 11 of the planar valve 10, respectively, and the twelfth passage 1012 communicates with the third passage 103 to form the fourth backwash flow passage 7104 communicating with the drain opening 11012 and the third opening 1103 of the valve body 11 of the planar valve 10, respectively. As shown in fig. 7A to 7F, 10C and 12C of the drawings, further, when the plane valve 10 is in the second backwash operation position, the ninth passage 109 is communicated with the first passage 101 and the fifth passage 105, respectively, the tenth passage 1010 is communicated with the second passage 102, the eleventh passage 1011 is communicated with the second passage 102, and the sixth passage 106 is blocked by the second fluid control surface 1220 of the movable valve plate 122. Thus, although the ninth channel 109 communicates with the first channel 101 and the fifth channel 105, respectively, the tenth channel 1010 communicates with the second channel 102, the eleventh channel 1011 communicates with the second channel 102, since the sixth channel 106 is blocked by the second fluid control surface 1220 of the movable valve plate 122, and the ninth channel 109, the tenth channel 1010 and the eleventh channel 1011 are blind through-holes, so that raw water can only flow from the second fluid opening 1108 of the planar valve 10 into the eighth channel 108, and further flow through the fourth channel 104, the fourth opening 1104, the second water outlet 522 of the second water treatment device 52 and into the second water treatment device 52, the waste water generated by back flushing the second water treatment device 52 flows from the second water inlet 521 of the second water treatment device 52 to the third opening 1103 of the planar valve 10, and is further discharged under the water pressure through the third channel 103, the twelfth channel 1012 and the drain opening 11012 of the planar valve 10. In other words, although the ninth passage 109 communicates with the first passage 101 and the fifth passage 105, respectively, the tenth passage 1010 communicates with the second passage 102, and the eleventh passage 1011 communicates with the second passage 102, water does not flow through the flow passages formed by them. Accordingly, when the planar valve 10 is in the second backwash operating position, the sixth passage 106 is blocked by the second fluid control surface 1220 of the movable valve plate 122 thereby blocking water flow through the sixth opening 1106 of the planar valve 10; although the ninth passage 109 communicates with the first passage 101 and the fifth passage 105, respectively, the tenth passage 1010 and the eleventh passage 1011 communicate with the second passage 102, the ninth passage 109, the tenth passage 1010 and the eleventh passage 1011 are blind through holes, and thus, water flow is prevented from flowing through the first opening 1101, the second opening 1102 and the fifth opening 1105 of the plane valve 10, so that water flow in the first water treatment device 51 and the third water treatment device 53 is prevented. In other words, although the ninth passage 109 communicates with the first passage 101 and the fifth passage 105, respectively, the tenth passage 1010 and the eleventh passage 1011 communicate with the second passage 102, so that the second opening 1102 of the plane valve 10, the first water treatment device 51, the first opening 1101 of the plane valve 10, the first passage 101, the ninth passage 109, the fifth passage 105, the fifth opening 1105 and the third water treatment device 53 communicate in sequence and the first water treatment device 51 and the third water treatment device 53 are connected in series, since the movable valve plate 122 blocks the flow of raw water to the first passage 101, the second passage 102, the fifth passage 105 and the sixth passage 106, it is ensured that only the second water treatment device 52 is backwashed.

It is noted that when the planar valve 10 is in the second backwash operation position, the second passage 102 and the sixth passage 106 are blocked by the movable valve plate 122, respectively, such that the second opening 1102 and the sixth opening 1106 are blocked, even though the ninth passage 109 is communicated with the first passage 101 and the fifth passage 105, respectively, such that the first opening 1101 and the fifth opening 1105 are communicated, no water flow in the first opening 1101 and the fifth opening 1105, that is, the first water treatment device 51 and the third water treatment device 53 are connected in series through the first opening 1101 and the fifth opening 1105, while the second opening 1102 and the sixth opening 1106 are blocked by the movable valve plate 122, such that the first water treatment device 51 and the third water treatment device 53 are isolated from the water flow, to ensure that only the second water treatment device 52 is backwashed by the raw water, thereby preventing the generated sewage flow to the first water treatment device 51 and/or the third water treatment device 53 while increasing the strength of the backwash water flow to the second water treatment device 52. Thus, the second water treatment device 52 of the water treatment machine of the present utility model is independently backwashed when the planar valve 10 is in the second backwash operating position.

As shown in fig. 11C, 11D and 12B of the drawings, illustratively, when the plane valve 10 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the second backwash operation position, raw water from the plane valve 10 flows into the second water treatment device 52 from the second water outlet 522 of the second water treatment device 52 under the action of water pressure, then flows from the second center pipe 524 to the second water treatment material 525 and backflushes the second water treatment material 525 under the action of water pressure, and generated sewage flows out from the second water inlet 521 of the second water treatment device 52 and flows to the third opening 1103 of the plane valve 10 under the action of water pressure, and then flows to the sewage discharge opening 11012 and is discharged through the fourth backwash flow passage 7104.

As shown in fig. 10D, 11F and 12D of the drawings, the flat valve 10 of the water treatment machine according to the embodiment of the present utility model further has a third back flushing operation position in which the eighth passage 108 of the flat valve 10 communicates with the sixth passage 106 when the flat valve 10 is in the third back flushing operation position, thereby forming the fifth backwash flow passage 7105 communicating with the second fluid opening 1108 and the sixth opening 1106 of the valve body 11 of the flat valve 10, respectively, and the twelfth passage 1012 communicates with the fifth passage 105, thereby forming the sixth backwash flow passage 7106 communicating with the blowdown opening 11012 and the fifth opening 1105 of the valve body 11 of the flat valve 10, respectively. As shown in fig. 7A to 7F, 10D and 12D of the drawings, further, when the plane valve 10 is in the third back flushing operation position, the ninth passage 109 communicates with the first passage 101, the tenth passage 1010 communicates with the second passage 102 and the third passage 103, respectively, the eleventh passage 1011 is blocked by the first fluid control surface 1210 of the fixed valve plate 121, and the fourth passage 104 is blocked by the second fluid control surface 1220 of the movable valve plate 122. Thus, although the ninth passage 109 communicates with the first passage 101, the tenth passage 1010 communicates with the second passage 102 and the third passage 103, respectively, since the fourth passage 104 is blocked by the second fluid control surface 1220 of the movable valve plate 122, and the ninth passage 109, the tenth passage 1010 and the eleventh passage 1011 are blind through-holes, so that raw water can only flow from the second fluid opening 1108 of the plane valve 10 into the eighth passage 108, and further flow through the sixth passage 106, the sixth opening 1106, the third water outlet 532 to the third water treatment device 53 and into the third water treatment device 53, the waste water generated by back flushing the third water treatment device 53 flows from the third water inlet 531 to the fifth opening 1105 of the plane valve 10, and is further discharged under the water pressure through the fifth passage 105, the twelfth passage 1012 and the drain opening 11012 of the plane valve 10. In other words, although the ninth passage 109 of the plane valve 10 communicates with the first passage 101, the tenth passage 1010 communicates with the second passage 102 and the third passage 103, respectively, water does not flow through the flow passages formed by them. Accordingly, when the planar valve 10 is in the third back flush operating position, the fourth passage 104 is blocked by the second flow control surface 1220 of the movable valve plate 122, thereby blocking water flow through the fourth opening 1104 of the planar valve 10; although the ninth passage 109 communicates with the first passage 101, the tenth passage 1010 communicates with the second passage 102 and the third passage 103, respectively, both the ninth passage 109 and the tenth passage 1010 are blind through-holes, and thus, water flow is prevented from flowing through the first opening 1101, the second opening 1102 and the third opening 1103 of the planar valve 10, so that water flow in the first water treatment device 51 and the second water treatment device 52 is prevented. In other words, although the ninth passage 109 communicates with the first passage 101, the tenth passage 1010 communicates with the second passage 102 and the third passage 103, respectively, so that the ninth passage 109, the first passage 101, the first opening 1101, the first water treatment device 51, the second opening 1102, the second passage 102, the tenth passage 1010, the third passage 103, the third opening 1103, the second water treatment device 52, the fourth opening 1104 and the fourth passage 104 of the plane valve 10 are sequentially communicated and the first water treatment device 51 and the second water treatment device 52 are connected in series, since the movable valve plate 122 blocks the flow of raw water to the first passage 101, the second passage 102, the third passage 103 and the fourth passage 104, it is ensured that only the third water treatment device 53 is backwashed.

It is noted that when the planar valve 10 is in the third back flush operating position, the first channel 101 (or the flow passage formed by the ninth channel 109 communicating with the first channel 101) and the fourth channel 104 are blocked by the movable valve plate 122, respectively, such that the first opening 1101 and the fourth opening 1104 are blocked, even though the tenth channel 1010 is communicated with the second channel 102 and the third channel 103, respectively, such that the second opening 1102 and the third opening 1103 are communicated, but no water flow in the second opening 1102 and the third opening 1103 is caused, that is, the first water treatment device 51 and the second water treatment device 52 are connected in series through the second opening 1102 and the third opening 1103, while the first opening 1101 and the fourth opening 1104 are blocked by the movable valve plate 122, such that the first water treatment device 51 and the second water treatment device 52 are isolated from the water flow, to ensure that only the third water treatment device 53 is back flushed, thereby increasing the strength of the third water treatment device 53 and also preventing the second water treatment device 51 and/or the second water treatment device 52 from generating the second water treatment flow. Thus, the third water treatment device 53 of the water treatment machine of the present utility model is separately backwashed when the planar valve 10 is in the third backwashed operating position.

As shown in fig. 11C, 11D and 12B of the drawings, illustratively, when the plane valve 10 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the third reverse flushing operation position, raw water from the plane valve 10 flows into the third water treatment device 53 from the third water outlet 532 of the third water treatment device 53 under the action of water pressure, then flows into the third water treatment material 535 and reversely flushes the third water treatment material 535 from the third central pipe 534 under the action of water pressure, and the generated sewage flows out from the third water inlet 531 of the third water treatment device 53 and flows into the fifth opening 1105 of the plane valve 10 under the action of water pressure, and then flows into the sewage discharge opening 11012 and is discharged through the sixth backwash flow passage 7106.

As shown in fig. 10E, 11G and 12E of the drawings, the flat valve 10 of the water treatment machine according to the embodiment of the present utility model further has a first forward flushing operation position in which the eighth passage 108 of the flat valve 10 communicates with the first passage 101 when the flat valve 10 is in the first forward flushing operation position, thereby forming the first forward flushing passage 7201 communicating with the second fluid opening 1108 and the first opening 1101 of the valve body 11 of the flat valve 10, respectively, and the twelfth passage 1012 communicates with the second passage 102, thereby forming the second forward flushing passage 7202 communicating with the drain opening 11012 and the second opening 1102 of the valve body 11 of the flat valve 10, respectively. As shown in fig. 7A to 7F, 10E and 12E of the drawings, further, when the plane valve 10 is in the first forward flushing operation position, the ninth passage 109 communicates with the third passage 103, the tenth passage 1010 communicates with the fifth passage 105 and the sixth passage 106, respectively, the eleventh passage 1011 is blocked by the first fluid control surface 1210 of the fixed valve plate 121, and the fourth passage 104 is blocked by the second fluid control surface 1220 of the movable valve plate 122. Thus, when the planar valve 10 is in the first forward flushing position, although the ninth passage 109 of the planar valve 10 is in communication with the third passage 103, the tenth passage 1010 is in communication with the fifth passage 105 and the sixth passage 106, respectively, since the fourth passage 104 is blocked by the second fluid control surface 1220 of the movable valve plate 122, and the ninth passage 109, the tenth passage 1010 and the eleventh passage 1011 are blind through-holes, so that raw water can only flow into the eighth passage 108 from the second fluid opening 1108 of the planar valve 10, and further flow through the first passage 101, the first opening 1101, the first water inlet 511 to the first water treatment device 51 and the first water treatment device 51, the waste water generated by forward flushing the first water treatment device 51 flows from the first water outlet 512 of the first water treatment device 51 to the second opening 1102 of the planar valve 10, and is further discharged under the water pressure through the second passage 1012, the twelfth passage 12 and the drain opening 11012 of the planar valve 10. In other words, although the ninth passage 109 of the plane valve 10 communicates with the third passage 103, the tenth passage 1010 communicates with the fifth passage 105 and the sixth passage 106, respectively, water does not flow through the flow passages formed by them. Accordingly, when the planar valve 10 is in the first forward flushing operation, the fourth passage 104 is blocked by the second flow control surface 1220 of the movable valve plate 122, thereby blocking water from flowing through the fourth opening 1104 of the planar valve 10; although the ninth passage 109 communicates with the third passage 103, the tenth passage 1010 communicates with the fifth passage 105 and the sixth passage 106, respectively, both the ninth passage 109 and the tenth passage 1010 are blind through-holes, and thus water flow is prevented from flowing through the third, fifth and sixth openings 1103, 1105, 1106 of the planar valve 10, so that water flow in the second and third water treatment devices 52, 53 is prevented. In other words, although the ninth passage 109 communicates with the third passage 103, the tenth passage 1010 communicates with the fifth passage 105 and the sixth passage 106, respectively, such that the ninth passage 109, the third passage 103, the third opening 1103, the second water treatment device 52, the fourth opening 1104, the fourth passage 104 of the plane valve 10 communicate in sequence; the tenth passage 1010, the fifth passage 105, the fifth opening 1105, the third water treatment unit 53, the sixth opening 1106, the sixth passage 106, and the tenth passage 1010 of the plane valve 10 are sequentially communicated, but since the movable valve plate 122 blocks the flow of raw water to the third passage 103, the fourth passage 104, the fifth passage 105, and the sixth passage 106, it is ensured that only the first water treatment unit 51 is positively rinsed.

It is noted that when the flat valve 10 is in the first forward flushing position, the third passage 103 (or the passage formed by the communication of the ninth passage 109 with the third passage 103) and the fourth passage 104 are blocked by the movable valve plate 122, respectively, so that the third opening 1103 and the fourth opening 1104 are blocked, even if the tenth passage 1010 is communicated with the fifth passage 105 and the sixth passage 106, respectively, so that the fifth opening 1105 and the sixth opening 1106 are communicated, no water flow in the fifth opening 1105 and the sixth opening 1106 is caused, that is, the second water treatment device 52 and the third water treatment device 53 are isolated from the water flow, so that only the first water treatment device 51 is positively flushed, and the generated sewage is prevented from flowing to the second water treatment device 52 and/or the third water treatment device 53 while the strength of the water flow for positively flushing the first water treatment device 51 is improved. Thus, the first water treatment device 51 of the water treatment machine of the present utility model is solely positively flushed when the planar valve 10 is in the first positive flush operating position.

As shown in fig. 11C, 11D and 12B of the drawings, illustratively, when the plane valve 10 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the first forward flushing operation position, raw water from the plane valve 10 flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51 under the action of water pressure, and then the first water treatment material 515 is positively flushed under the action of water pressure, and generated sewage is collected by the first central pipe 514 and flows out from the first water outlet 512 of the first water treatment device 51, flows to the second opening 1102 of the plane valve 10 under the action of water pressure, and then flows to the sewage discharge opening 11012 and is discharged through the second forward flushing channel 7202.

As shown in fig. 10F, 11H and 12F of the drawings, the flat valve 10 of the water treatment machine according to the embodiment of the present utility model further has a second forward flushing operation position in which the eighth passage 108 of the flat valve 10 communicates with the third passage 103 when the flat valve 10 is in the second forward flushing operation position, thereby forming the third forward flushing passage 7203 communicating with the second fluid opening 1108 and the third opening 1103 of the valve body 11 of the flat valve 10, respectively, and the twelfth passage 1012 communicates with the fourth passage 104, thereby forming the fourth forward flushing passage 7204 communicating with the drain opening 11012 and the fourth opening 1104 of the valve body 11 of the flat valve 10, respectively. As shown in fig. 7A to 7F, 10F and 12F of the drawings, further, when the flat valve 10 is in the second positive flush operation position, the ninth passage 109 communicates with the sixth passage 106, the tenth passage 1010 communicates with the first passage 101, the eleventh passage 1011 is blocked by the first fluid control surface 1210 of the fixed valve plate 121, and the second passage 102 and the fifth passage 105 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively. Thus, when the planar valve 10 is in the second forward flushing position, although the ninth passage 109 of the planar valve 10 is in communication with the sixth passage 106 and the tenth passage 1010 is in communication with the first passage 101, since the second passage 102 and the fifth passage 105 are blocked by the second fluid control surface 1220 of the movable valve plate 122, and the ninth passage 109, the tenth passage 1010 and the eleventh passage 1011 are blind through-holes, raw water can only flow into the eighth passage 108 from the second fluid opening 1108 of the planar valve 10 and further flow through the third passage 103, the third opening 1103, the second water inlet 521 to the second water treatment device 52 and into the second water treatment device 52, waste water generated by forward flushing the second water treatment device 52 flows from the second water outlet 522 of the second water treatment device 52 to the fourth opening 1104 of the planar valve 10 and is further discharged under the water pressure through the fourth passage 104, the twelfth passage 1012 and the drain opening 11012 of the planar valve 10. In other words, although the ninth passage 109 communicates with the sixth passage 106, the tenth passage 1010 communicates with the first passage 101, the water flow does not flow through the flow passages formed by them. Accordingly, when the planar valve 10 is in the second forward flushing operation position, the second passage 102 and the fifth passage 105 are blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby preventing water from flowing through the second opening 1102 and the fifth opening 1105 of the planar valve 10; although the ninth passage 109 communicates with the sixth passage 106, the tenth passage 1010 communicates with the first passage 101, both the ninth passage 109 and the tenth passage 1010 are blind through-holes, and therefore, water flow is prevented from flowing through the first opening 1101 and the sixth opening 1106 of the planar valve 10, so that water flow in the first water treatment device 51 and the third water treatment device 53 is prevented. In other words, although the ninth passage 109 communicates with the sixth passage 106, the tenth passage 1010 communicates with the first passage 101, the tenth passage 1010 of the plane valve 10, the first passage 101, the first opening 1101 of the plane valve 10, the first water treatment device 51, the second opening 1102, the second passage 102 communicate sequentially, and the fifth passage 105, the fifth opening 1105, the third water treatment device 53, the sixth opening 1106, the sixth passage 106, and the ninth passage 109 communicate sequentially, since the movable valve plate 122 blocks the flow of raw water to the first passage 101, the second passage 102, the fifth passage 105, and the sixth passage 106, thereby ensuring that only the second water treatment device 52 is flushed forward.

It is noted that when the planar valve 10 is in the second forward flushing position, the first channel 101 (or the flow channel formed by the tenth channel 1010 and the first channel 101), the second channel 102, the fifth channel 105 and the sixth channel 106 (or the flow channel formed by the ninth channel 109 and the sixth channel 106) are blocked by the movable valve plate 122, respectively, such that the first opening 1101, the second opening 1102, the fifth opening 1105 and the sixth opening 1106 are blocked, that is, the first water treatment device 51 and the third water treatment device 53 are isolated from the water flow, so as to ensure that only the second water treatment device 52 is forward flushed, thereby preventing the generated sewage from flowing to the first water treatment device 51 and/or the third water treatment device 53 while improving the strength of the water flow for forward flushing the second water treatment device 52. Thus, the second water treatment device 52 of the water treatment machine of the present utility model is solely positively flushed when the planar valve 10 is in the second positive flush operating position.

As shown in fig. 11C, 11D and 12B of the drawings, illustratively, when the plane valve 10 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the second forward flushing operation position, raw water from the plane valve 10 flows into the second water treatment device 52 from the second water inlet 521 of the second water treatment device 52 under the action of water pressure, and then the second water treatment material 525 is flushed forward under the action of water pressure, and generated sewage is collected by the second central pipe 524 and flows out from the second water outlet 522 of the second water treatment device 52, flows to the fourth opening 1104 of the plane valve 10 under the action of water pressure, and then flows to the sewage discharge opening 11012 and is discharged through the fourth forward flushing channel 7204.

As shown in fig. 10G, 11I and 12G of the drawings, the flat valve 10 of the water treatment machine according to the embodiment of the present utility model further has a third forward flushing operation position in which the eighth passage 108 of the flat valve 10 communicates with the fifth passage 105 when the flat valve 10 is in the third forward flushing operation position, thereby forming the fifth forward flushing passage 7205 communicating with the second fluid opening 1108 and the fifth opening 1105 of the valve body 11 of the flat valve 10, respectively, and the twelfth passage 1012 communicates with the sixth passage 106, thereby forming the sixth forward flushing passage 7206 communicating with the drain opening 11012 and the sixth opening 1106 of the valve body 11 of the flat valve 10, respectively. As shown in fig. 7A to 7F, 10G and 12G of the drawings, further, when the plane valve 10 is in the third forward flushing operation position, the ninth passage 109 communicates with the second passage 102, the tenth passage 1010 communicates with the fourth passage 104, the eleventh passage 1011 communicates with the fifth passage 105, and the first passage 101 and the third passage 103 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively. Thus, when the planar valve 10 is in the third forward flushing position, although the ninth passageway 109 is in communication with the second passageway 102, the tenth passageway 1010 is in communication with the fourth passageway 104, and the eleventh passageway 1011 is in communication with the fifth passageway 105, since the first passageway 101 and the third passageway 103 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, and the ninth passageway 109, the tenth passageway 1010 and the eleventh passageway 1011 are blind vias, such that raw water can only flow from the second fluid opening 1108 of the planar valve 10 into the eighth passageway 108, and further flow through the fifth passageway 105, the fifth opening 1105 to the third water inlet 531 of the third water treatment device 53 and into the third water treatment device 53, forward flush the waste water generated by the third water treatment device 53 from the third water treatment device 53 to the sixth opening 1106 of the planar valve 10, and further out under hydraulic pressure through the sixth passageway 106, the twelfth opening 1012 and the drain opening 1012 of the planar valve 10. In other words, although the ninth passage 109 communicates with the second passage 102, the tenth passage 1010 communicates with the fourth passage 104, and the eleventh passage 1011 communicates with the fifth passage 105, water does not flow through the flow passages formed by them. Accordingly, when the planar valve 10 is in the third forward flushing operation position, the first and third passages 101 and 103 are blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby blocking water from flowing through the first and third openings 1101 and 1103 of the planar valve 10; although the ninth passage 109 communicates with the second passage 102, the tenth passage 1010 communicates with the fourth passage 104, both the ninth passage 109 and the tenth passage 1010 are blind through-holes, and therefore, water flow is prevented from flowing through the second opening 1102 and the fourth opening 1104 of the planar valve 10, so that water flow in the first water treatment device 51 and the second water treatment device 52 is prevented. In other words, although the ninth passage 109 communicates with the second passage 102, the tenth passage 1010 communicates with the fourth passage 104, the ninth passage 109, the second passage 102, the second opening 1102, the first water treatment device 51, the first opening 1101, the first passage 101 of the plane valve 10 communicate in sequence, and the tenth passage 1010, the fourth passage 104, the fourth opening 1104, the second water treatment device 52, the third opening 1103 and the third passage 103 of the plane valve 10 communicate in sequence, since the movable valve plate 122 blocks the flow of raw water to the first passage 101, the second passage 102, the third passage 103 and the fourth passage 104, it is ensured that only the third water treatment device 53 is flushed in the forward direction.

It is noted that when the planar valve 10 is in the third positive flush position, the first channel 101, the second channel 102 (or the channel formed by the ninth channel 109 and the second channel 102), the third channel 103 and the fourth channel 104 (or the channel formed by the tenth channel 1010 and the fourth channel 104) are blocked by the movable valve plate 122, respectively, such that the first opening 1101, the second opening 1102, the third opening 1103 and the fourth opening 1104 are blocked, that is, the first water treatment device 51 and the second water treatment device 52 are isolated from the water flow, so as to ensure that only the third water treatment device 53 is positively flushed, thereby preventing the generated sewage from flowing to the first water treatment device 51 and/or the second water treatment device 52 while improving the strength of the water flow for positively flushing the third water treatment device 53. Thus, the third water treatment device 53 of the water treatment machine of the present utility model is solely positively flushed when the planar valve 10 is in the third positive flush operating position.

As shown in fig. 11C, 11D and 12B of the drawings, illustratively, when the plane valve 10 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the third forward flushing operation position, raw water from the plane valve 10 flows into the third water treatment device 53 from the third water inlet 531 of the third water treatment device 53 under the water pressure, and then the third water treatment material 535 is positively flushed under the water pressure, and the generated sewage is collected by the third central pipe 534 and flows out from the third water outlet 532 of the third water treatment device 53 and flows to the sixth opening 1106 of the plane valve 10 under the water pressure, and then flows to the sewage discharge opening 11012 and is discharged through the sixth forward flushing channel 7206.

As shown in fig. 6C to 10G of the drawings, the fifth passage 105 of the plane valve 10 of the water treatment machine according to the embodiment of the present utility model has a first communication portion 1051 and a second communication portion 1052, wherein the first communication portion 1051 of the fifth passage 105 communicates with the fifth opening 1105, and the second communication portion 1052 of the fifth passage 105 communicates with the fifth opening 1105. Preferably, the fifth channel 105 of the plane valve 10 further has a third communication portion 1053 extending between the first communication portion 1051 and the second communication portion 1052, the first communication portion 1051 of the fifth channel 105 communicates with the fifth opening 1105, the second communication portion 1052 of the fifth channel 105 communicates with the first communication portion 1051 through the third communication portion 1053, that is, the second communication portion 1052 of the fifth channel 105 communicates with the fifth opening 1105 through the third communication portion 1053, the first communication portion 1051. Preferably, the fourth passage 104 and the first passage 101 of the plane valve 10 are provided outside the third communication portion 1053.

As shown in fig. 16A to 16G, 19A and 21A of the drawings, when the plane valve 10A is in the water treatment operation position, the twelfth channel 1012A communicates with the thirteenth channel 1013A, and although the twelfth channel 1012A communicates with the thirteenth channel 1013A, water cannot flow through the flow passage formed by the fixed valve plate 121A of the plane valve 10A due to the obstruction thereof.

As shown in fig. 11A, 11B and 12A of the drawings, illustratively, when the plane valve 10A of the water treatment machine according to the embodiment of the present utility model is controlled to be at the water treatment working position, raw water from the plane valve 10A flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51 under the action of water pressure, and after being treated (e.g., purified or softened) by the first water treatment material 515 under the action of water pressure, generated primary treatment water is collected by the first central tube 514 and flows out from the first water outlet 512 of the first water treatment device 51; under the action of water pressure, the primary treatment water further flows to the second water inlet 521 of the second water treatment device 52 and flows into the second water treatment device 52 through the second opening 1102, the second passage 102A, the ninth passage 109A, the third passage 103A, and the third opening 1103 of the planar valve 10A, and under the action of water pressure, after being treated (e.g., purified or softened) by the second water treatment material 525, the generated secondary treatment water is collected by the second central tube 524 and flows out from the second water outlet 522 of the second water treatment device 52; the secondary treated water further flows to the third water inlet 531 of the third water treatment device 53 and into the third water treatment device 53 through the fourth opening 1104, the fourth passage 104A, the tenth passage 1010A, the fifth passage 105A, the fifth opening 1105 of the plane valve 10A under the action of the water pressure, and after being treated (e.g., purified or softened) by the third water treatment material 535 under the action of the water pressure, the generated tertiary treated water is collected by the third center pipe 534 and flows out from the third water outlet 532 of the third water treatment device 53 and toward the sixth opening 1106 of the valve body 11A of the plane valve 10A, and is then supplied through the sixth passage 106A, the eleventh passage 1011A, the seventh passage 107A, and the first fluid opening 1107 of the plane valve 10A.

As shown in fig. 19B, 20D and 21B of the drawings, the flat valve 10A of the water treatment machine according to the embodiment of the present utility model further has a first back flushing operation position in which the eighth passage 108A of the flat valve 10A communicates with the second passage 102A when the flat valve 10A is in the first back flushing operation position, thereby forming a first back flushing flow passage 7101A communicating with the second fluid opening 1108 and the second opening 1102 of the valve body 11A of the flat valve 10A, respectively, and the twelfth passage 1012A communicates with the first passage 101A and the thirteenth passage 1013A, respectively, thereby forming a second back flushing flow passage 7102A communicating with the drain opening 11012A and the first opening 1101 of the valve body 11A of the flat valve 10A, respectively. As shown in fig. 16A to 16G, 19B and 21B of the drawings, further, when the plane valve 10A is in the first backwash operation position, the ninth passage 109A communicates with the fourth passage 104A and the fifth passage 105A, respectively, the tenth passage 1010A communicates with the fifth passage 105A, the eleventh passage 1011A communicates with the first passage 101A, and the third passage 103A and the sixth passage 106A are blocked by the second fluid control surface 1220A of the movable valve plate 122A, respectively. Thus, although the ninth passageway 109A communicates with the fourth passageway 104A and the fifth passageway 105A, respectively, the tenth passageway 1010A communicates with the fifth passageway 105A, and the eleventh passageway 1011A communicates with the first passageway 101A, since the third passageway 103A and the sixth passageway 106A are blocked by the second fluid control surface 1220A of the movable valve plate 122A, respectively, and the ninth passageway 109A, the tenth passageway 1010A and the eleventh passageway 1011A are blind through-holes, so that raw water can only flow from the second fluid opening 1108 of the planar valve 10A into the eighth passageway 108A, and further flow through the second passageway 102A, the second opening 1102, the first water outlet 512 to the first water treatment device 51 and into the first water treatment device 51, back flush the waste water generated by the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51 to the first opening 1101 of the planar valve 10A, and further drain through the first passageway 101A, the thirteenth passageway 1013 of the planar valve 10A and the thirteenth passageway 1012 under the water pressure. In other words, although the ninth passage 109A communicates with the fourth passage 104A and the fifth passage 105A, respectively, the tenth passage 1010A communicates with the fifth passage 105A, and the eleventh passage 1011A communicates with the first passage 101A, water does not flow through the flow passages formed by them. Accordingly, when the planar valve 10A is in the first backwash operation position, the third passage 103A and the sixth passage 106A are blocked by the second fluid control surface 1220A of the movable valve plate 122A, respectively, thereby blocking water flow through the third opening 1103 and the sixth opening 1106 of the planar valve 10A; although the ninth passage 109A communicates with the fourth passage 104A and the fifth passage 105A, respectively, the ninth passage 109A is a blind via, and therefore, water flow is prevented from flowing through the fourth opening 1104 and the fifth opening 1105 of the planar valve 10A, so that water flow in the second water treatment apparatus 52 and the third water treatment apparatus 53 is prevented. In other words, although the ninth passage 109A communicates with the fourth passage 104A and the fifth passage 105A, respectively, the third passage 103A, the third opening 1103, the second water treatment device 52, the fourth opening 1104, the fourth passage 104A, the ninth passage 109A, the fifth passage 105A, the fifth opening 1105 and the third water treatment device 53 of the plane valve 10A are communicated in sequence and the second water treatment device 52 and the third water treatment device 53 are connected in series, since the movable valve plate 122A blocks the flow of raw water to the third passage 103A, the fourth passage 104A, the fifth passage 105A and the sixth passage 106A, thereby ensuring that only the first water treatment device 51 is backwashed.

It is noted that when the planar valve 10A is in the first backwash operation position, the third passage 103A and the sixth passage 106A are blocked by the movable valve plate 122A, respectively, such that the third opening 1103 and the sixth opening 1106 are blocked, even though the ninth passage 109A is in communication with the fourth passage 104A and the fifth passage 105A, respectively, such that the fourth opening 1104 and the fifth opening 1105 are in communication, no water flow in the fourth opening 1104 and the fifth opening 1105, that is, the second water treatment device 52 and the third water treatment device 53 are connected in series through the fourth opening 1104 and the fifth opening 1105, while the third opening 1103 and the sixth opening 1106 are further blocked by the movable valve plate 122A, such that the second water treatment device 52 and the third water treatment device 53 are isolated from the water flow, to ensure that only the first water treatment device 51 is backwashed, thereby preventing the second water treatment device 52 and/or the third water treatment device 53 from generating a water flow of the second water treatment device 52 and/or the third water treatment device 53 while increasing the strength of the backwash of the first water treatment device 51. Thus, the first water treatment device 51 of the water treatment machine of the present utility model is independently backwashed when the planar valve 10A is in the first backwash operating position.

As shown in fig. 19B, 20D and 21B of the drawings, illustratively, when the plane valve 10A of the water treatment machine according to the embodiment of the present utility model is controlled to be in the first backwash operation position, raw water from the plane valve 10A flows into the first water treatment device 51 from the first water outlet 512 of the first water treatment device 51 under the action of water pressure, then flows from the first central pipe 514 to the first water treatment material 515 and backflushes the first water treatment material 515 under the action of water pressure, and generated sewage flows out from the first water inlet 511 of the first water treatment device 51 and flows to the first opening 1101 of the plane valve 10A under the action of water pressure, then flows to the drain opening 11012A and is discharged through the second backwash flow passage 7102A.

As shown in fig. 19C, 20E and 21C of the drawings, the flat valve 10A of the water treatment machine according to the embodiment of the present utility model further has a second backwash operation position in which the eighth passage 108A of the flat valve 10A communicates with the fourth passage 104A when the flat valve 10A is in the second backwash operation position, thereby forming a third backwash flow passage 7103A communicating with the second fluid opening 1108 of the valve body 11A and the fourth opening 1104 of the flat valve 10A, respectively, and the twelfth passage 1012A communicates with the third passage 103A and the thirteenth passage 1013A, respectively, thereby forming a fourth backwash flow passage 7104A communicating with the drain opening 11012A and the third opening 1103 of the valve body 11A of the flat valve 10A, respectively. As shown in fig. 16A to 16G, 19C and 21C of the drawings, further, when the plane valve 10A is in the second backwash operation position, the ninth passage 109A communicates with the first passage 101A and the fifth passage 105A, respectively, the tenth passage 1010A communicates with the second passage 102A, the eleventh passage 1011A communicates with the second passage 102A, and the sixth passage 106A is blocked by the second fluid control surface 1220A of the movable valve plate 122A. Although the ninth passageway 109A communicates with the first passageway 101A and the fifth passageway 105A, respectively, the tenth passageway 1010A communicates with the second passageway 102A, the eleventh passageway 1011A communicates with the second passageway 102A, since the sixth passageway 106A is blocked by the second fluid control surface 1220A of the movable valve plate 122A, and the ninth passageway 109A, the tenth passageway 1010A and the eleventh passageway 1011A are blind through holes, so that raw water can only flow from the second fluid opening 1108 of the planar valve 10A into the eighth passageway 108A, and further flow through the fourth passageway 104A, the fourth opening 1104, the second water outlet 522 to the second water treatment device 52 and into the second water treatment device 52, back flush the waste water generated by the second water treatment device 52 flows from the second water inlet 1103A of the second water treatment device 52 to the third opening 521 of the planar valve 10A, and is further discharged under water pressure through the third fluid opening 1108 of the planar valve 10A, the twelfth passageway 1013A, the thirteenth opening 521 and the drain opening 11012A of the planar valve 10A. In other words, although the ninth passage 109A communicates with the first passage 101A and the fifth passage 105A, respectively, the tenth passage 1010A communicates with the second passage 102A, and the eleventh passage 1011A communicates with the second passage 102A, water does not flow through the flow passages formed by them. Accordingly, when the planar valve 10A is in the second backwash operation position, the sixth passage 106A is blocked by the second fluid control surface 1220A of the movable valve plate 122A thereby blocking water flow through the sixth opening 1106 of the planar valve 10A; although the ninth passage 109A communicates with the first passage 101A and the fifth passage 105A, respectively, the tenth passage 1010A and the eleventh passage 1011A communicate with the second passage 102A, the ninth passage 109A, the tenth passage 1010A and the eleventh passage 1011A are blind through holes, and therefore, water flow is prevented from flowing through the first opening 1101, the second opening 1102 and the fifth opening 1105 of the plane valve 10A, so that the flow of water in the first water treatment device 51 and the third water treatment device 53 is prevented. In other words, although the ninth passage 109A communicates with the first passage 101A and the fifth passage 105A, respectively, the tenth passage 1010A and the eleventh passage 1011A communicate with the second passage 102A, the second opening 1102 of the plane valve 10A, the first water treatment device 51, the first opening 1101 of the plane valve 10A, the first passage 101A, the ninth passage 109A, the fifth passage 105A, the fifth opening 1105 and the third water treatment device 53 communicate in sequence, and the first water treatment device 51 and the third water treatment device 53 are connected in series, since the movable valve plate 122A blocks the flow of raw water to the first passage 101A, the second passage 102A, the fifth passage 105A and the sixth passage 106A, it is ensured that only the second water treatment device 52 is backwashed.

It is noted that when the planar valve 10A is in the second backwash operation position, the second passage 102A and the sixth passage 106A are blocked by the movable valve plate 122A, respectively, such that the second opening 1102 and the sixth opening 1106 are blocked, even though the ninth passage 109A is in communication with the first passage 101A and the fifth passage 105A, respectively, such that the first opening 1101 and the fifth opening 1105 are in communication, no water flow in the first opening 1101 and the fifth opening 1105, that is, the first water treatment device 51 and the third water treatment device 53 are connected in series through the first opening 1101 and the fifth opening 1105, while the second opening 1102 and the sixth opening 1106 are blocked by the movable valve plate 122A, such that the first water treatment device 51 and the third water treatment device 53 are isolated from the water flow, to ensure that only the second water treatment device 52 is backwashed, thereby preventing the first water treatment device 51 and/or the third water treatment device 53 from generating a water flow of the first water treatment device 51 while increasing the strength of backwash of the second water treatment device 52. Thus, the second water treatment device 52 of the water treatment machine of the present utility model is independently backwashed when the planar valve 10A is in the second backwash operating position.

As shown in fig. 19C, 20E and 21C of the drawings, illustratively, when the plane valve 10A of the water treatment machine according to the embodiment of the present utility model is controlled to be in the second backwash operation position, raw water from the plane valve 10A flows into the second water treatment device 52 from the second water outlet 522 of the second water treatment device 52 under the action of water pressure, then flows from the second center pipe 524 to the second water treatment material 525 and backflushes the second water treatment material 525 under the action of water pressure, and generated sewage flows out from the second water inlet 521 of the second water treatment device 52 and flows to the third opening 1103 of the plane valve 10A under the action of water pressure, and then flows to the drain opening 11012A and is discharged through the fourth backwash flow passage 7104A.

As shown in fig. 19D, 20F and 21D of the drawings, the flat valve 10A of the water treatment machine according to the embodiment of the present utility model further has a third back flushing operation position in which the eighth passage 108A of the flat valve 10A communicates with the sixth passage 106A when the flat valve 10A is in the third back flushing operation position, thereby forming a fifth backwash flow passage 7105A communicating with the second fluid opening 1108 and the sixth opening 1106 of the valve body 11A of the flat valve 10A, respectively, and the twelfth passage 1012A communicates with the fifth passage 105A and the thirteenth passage 1013A, respectively, thereby forming a sixth backwash flow passage 7106A communicating with the drain opening 11012A and the fifth opening 1105 of the valve body 11A of the flat valve 10A, respectively. As shown in fig. 16A to 16G, 19D and 21D of the drawings, further, when the plane valve 10A is in the third reverse flushing operation position, the ninth passage 109A communicates with the first passage 101A, the tenth passage 1010A communicates with the second passage 102A and the third passage 103A, respectively, the eleventh passage 1011A is blocked by the first fluid control surface 1210A of the fixed valve plate 121A, and the fourth passage 104A is blocked by the second fluid control surface 1220A of the movable valve plate 122A. Although the ninth passage 109A communicates with the first passage 101A, the tenth passage 1010A communicates with the second passage 102A and the third passage 103A, respectively, since the fourth passage 104A is blocked by the second fluid control surface 1220A of the movable valve plate 122A, and the ninth passage 109A, the tenth passage 1010A and the eleventh passage 1011A are blind through-holes, so that raw water can only flow into the eighth passage 108A from the second fluid opening 1108 of the plane valve 10A, and further flow into the third water treatment device 53 through the sixth passage 106A, the sixth opening 1106, the third water outlet 532 of the third water treatment device 53 and the third water treatment device 53, waste water generated by back flushing the third water treatment device 53 flows from the third water inlet 531 of the third water treatment device 53 to the fifth opening 1105 of the plane valve 10A, and is further discharged under the water pressure through the fifth passage 105A, the twelfth passage 1012A, the thirteenth passage 1013A and the drain opening 12A of the plane valve 10A. In other words, although the ninth passage 109A of the plane valve 10A communicates with the first passage 101A, the tenth passage 1010A communicates with the second passage 102A and the third passage 103A, respectively, water does not flow through the flow passages formed by them. Accordingly, when the planar valve 10A is in the third back flush operating position, the fourth passage 104A is blocked by the second flow control surface 1220A of the movable valve plate 122A, thereby blocking water flow through the fourth opening 1104 of the planar valve 10A; although the ninth passage 109A communicates with the first passage 101A, the tenth passage 1010A communicates with the second passage 102A and the third passage 103A, respectively, both the ninth passage 109A and the tenth passage 1010A are blind through holes, and thus, water flow is prevented from flowing through the first opening 1101, the second opening 1102 and the third opening 1103 of the plane valve 10A, so that water flow in the first water treatment device 51 and the second water treatment device 52 is prevented. In other words, although the ninth passage 109A communicates with the first passage 101A, the tenth passage 1010A communicates with the second passage 102A and the third passage 103A, respectively, so that the ninth passage 109A, the first passage 101A, the first opening 1101, the first water treatment device 51, the second opening 1102, the second passage 102A, the tenth passage 1010A, the third passage 103A, the third opening 1103, the second water treatment device 52, the fourth opening 1104 and the fourth passage 104A of the plane valve 10A communicate in series with the first water treatment device 51 and the second water treatment device 52, respectively, only the third water treatment device 53 is ensured to be backwashed due to the blocking of the flow of raw water to the first passage 101A, the second passage 102A, the third passage 103A and the fourth passage 104A by the movable valve plate 122A.

It is noted that when the planar valve 10A is in the third back flushing operation position, the first channel 101A (or the flow channel formed by the ninth channel 109A communicating with the first channel 101A) and the fourth channel 104A are blocked by the movable valve plate 122A, respectively, so that the first opening 1101 and the fourth opening 1104 are blocked, even though the tenth channel 1010A is communicated with the second channel 102A and the third channel 103A, respectively, so that the second opening 1102 and the third opening 1103 are communicated, but no water flow in the second opening 1102 and the third opening 1103 is caused, that is, the first water treatment device 51 and the second water treatment device 52 are connected in series through the second opening 1102 and the third opening 1103, while the first opening 1101 and the fourth opening 1104 are blocked by the movable valve plate 122A, so that the first water treatment device 51 and the second water treatment device 52 are isolated from the water flow, so as to ensure that only the third water treatment device 53 is communicated with the second channel 102A, so that the water treatment device 51 and the second water treatment device 52 can be further treated with the second water treatment device 53 is prevented from being backwashed by the second water treatment device 53, or the second water treatment device 52 is also able to prevent the water treatment device from being flushed by the second water treatment device. Thus, the third water treatment device 53 of the water treatment machine of the present utility model is separately backwashed when the planar valve 10A is in the third backwashed operating position.

As shown in fig. 19D, 20F and 21D of the drawings, illustratively, when the plane valve 10A of the water treatment machine according to the embodiment of the present utility model is controlled to be in the third reverse flushing operation position, raw water from the plane valve 10A flows into the third water treatment device 53 from the third water outlet 532 of the third water treatment device 53 under the action of water pressure, then flows into the third water treatment material 535 from the third central pipe 534 and reversely flushes the third water treatment material 535 under the action of water pressure, and generated sewage flows out from the third water inlet 531 of the third water treatment device 53 and flows into the fifth opening 1105 of the plane valve 10A under the action of water pressure, and then flows into the drain opening 11012A and is discharged through the sixth backwash flow passage 7106A.

As shown in fig. 19E, 20G and 21E of the drawings, the flat valve 10A of the water treatment machine according to the embodiment of the present utility model further has a first positive flushing operation position in which the eighth passage 108A of the flat valve 10A communicates with the first passage 101A when the flat valve 10A is in the first positive flushing operation position, thereby forming a first positive flushing passage 7201A communicating with the second fluid opening 1108 and the first opening 1101 of the valve body 11A of the flat valve 10A, respectively, and the twelfth passage 1012A communicates with the second passage 102A and the thirteenth passage 1013A, respectively, thereby forming a second positive flushing passage 7202A communicating with the drain opening 11012A and the second opening 1102 of the valve body 11A of the flat valve 10A, respectively. As shown in fig. 16A to 16G, 19E and 21E of the drawings, further, when the flat valve 10A is at the first positive flushing operation position, the ninth passage 109A communicates with the third passage 103A, the tenth passage 1010A communicates with the fifth passage 105A and the sixth passage 106A, respectively, the eleventh passage 1011A is blocked by the first fluid control surface 1210A of the fixed valve plate 121A, and the fourth passage 104A is blocked by the second fluid control surface 1220A of the movable valve plate 122A. Thus, when the planar valve 10A is in the first forward flushing position, although the ninth passageway 109A of the planar valve 10A is in communication with the third passageway 103A, the tenth passageway 1010A is in communication with the fifth passageway 105A and the sixth passageway 106A, respectively, since the fourth passageway 104A is blocked by the second fluid control surface 1220A of the movable valve plate 122A, and the ninth passageway 109A, the tenth passageway 1010A and the eleventh passageway 1011A are blind-in-passage, so that raw water can only flow from the second fluid opening 1108 of the planar valve 10A into the eighth passageway 108A and further through the first passageway 101A, the first opening 1101, the first water inlet 511 to the first water treatment device 51 and into the first water treatment device 51, forward flush the waste water generated by the first water treatment device 51 from the first water outlet 512 of the first water treatment device 51 to the second opening 1102 of the planar valve 10A, and further out of the drain opening 1013 through the second passageway 102A, the thirteenth passageway 110A and the thirteenth passageway 12A of the planar valve 10A under the water pressure. In other words, although the ninth passage 109A of the plane valve 10A communicates with the third passage 103A, the tenth passage 1010A communicates with the fifth passage 105A and the sixth passage 106A, respectively, water does not flow through the flow passages formed by them. Accordingly, when the planar valve 10A is in the first forward flushing operation, the fourth passage 104A is blocked by the second fluid control surface 1220A of the movable valve plate 122A, thereby blocking water flow through the fourth opening 1104 of the planar valve 10A; although the ninth passage 109A communicates with the third passage 103A, the tenth passage 1010A communicates with the fifth passage 105A and the sixth passage 106A, respectively, both the ninth passage 109A and the tenth passage 1010A are blind through-holes, and therefore, water flow is prevented from flowing through the third, fifth and sixth openings 1103, 1105 and 1106 of the planar valve 10A, so that water flow in the second and third water treatment devices 52 and 53 is prevented. In other words, although the ninth passage 109A communicates with the third passage 103A, the tenth passage 1010A communicates with the fifth passage 105A and the sixth passage 106A, respectively, such that the ninth passage 109A, the third passage 103A, the third opening 1103, the second water treatment device 52, the fourth opening 1104 and the fourth passage 104A of the plane valve 10A communicate sequentially; the tenth passage 1010A, the fifth passage 105A, the fifth opening 1105, the third water treatment unit 53, the sixth opening 1106, the sixth passage 106A, and the tenth passage 1010A of the plane valve 10A are sequentially communicated, but since the movable valve plate 122 blocks the flow of raw water to the third passage 103A, the fourth passage 104A, the fifth passage 105A, and the sixth passage 106A, it is ensured that only the first water treatment unit 51 is positively rinsed.

It is noted that when the planar valve 10A is in the first forward flushing position, the third passage 103A (or the passage formed by the communication of the ninth passage 109A with the third passage 103A) and the fourth passage 104A are blocked by the movable valve plate 122A, respectively, so that the third opening 1103 and the fourth opening 1104 are blocked, even if the tenth passage 1010A is communicated with the fifth passage 105A and the sixth passage 106A, respectively, so that the fifth opening 1105 and the sixth opening 1106 are communicated, no water flows in the fifth opening 1105 and the sixth opening 1106, that is, the second water treatment device 52 and the third water treatment device 53 are isolated from the water flow, so that only the first water treatment device 51 is positively flushed, and thus the generated sewage is prevented from flowing to the second water treatment device 52 and/or the third water treatment device 53 while the strength of the water flow for positively flushing the first water treatment device 51 is improved. Thus, the first water treatment device 51 of the water treatment machine of the present utility model is solely positively flushed when the planar valve 10A is in the first positive flush operating position.

As shown in fig. 19E, 20G and 21E of the drawings, illustratively, when the plane valve 10A of the water treatment machine according to the embodiment of the present utility model is controlled to be in the first forward flushing operation position, raw water from the plane valve 10A flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51 under the action of water pressure, and then the first water treatment material 515 is flushed forward under the action of water pressure, and generated sewage is collected by the first central pipe 514 and flows out from the first water outlet 512 of the first water treatment device 51, flows to the second opening 1102 of the plane valve 10A under the action of water pressure, and then flows to the drain opening 11012A and is discharged through the second forward flushing flow path 7202A.

As shown in fig. 19F, 20H and 21F of the drawings, the flat valve 10A of the water treatment machine according to the embodiment of the present utility model further has a second positive washing operation position in which the eighth passage 108A of the flat valve 10A communicates with the third passage 103A when the flat valve 10A is in the second positive washing operation position, thereby forming a third positive washing passage 7203A communicating with the second fluid opening 1108 and the third opening 1103 of the valve body 11A of the flat valve 10A, respectively, and the twelfth passage 1012A communicates with the fourth passage 104A and the thirteenth passage 1013A, respectively, thereby forming a fourth positive washing passage 7204A communicating with the drain opening 11012A and the fourth opening 1104 of the valve body 11A of the flat valve 10A, respectively. As shown in fig. 16A to 16G, 19F and 21F of the drawings, further, when the plane valve 10A is in the second positive purge operation position, the ninth passage 109A communicates with the sixth passage 106A, the tenth passage 1010A communicates with the first passage 101A, the eleventh passage 1011A is blocked by the first fluid control surface 1210A of the fixed valve plate 121A, and the second passage 102A and the fifth passage 105A are blocked by the second fluid control surface 1220A of the movable valve plate 122A, respectively. Thus, when the planar valve 10A is in the second forward flushing position, although the ninth passageway 109A of the planar valve 10A is in communication with the sixth passageway 106A, the tenth passageway 1010A is in communication with the first passageway 101A, since the second passageway 102A and the fifth passageway 105A are blocked by the second fluid control surface 1220A of the movable valve plate 122A, and the ninth passageway 109A, the tenth passageway 1010A and the eleventh passageway 1011A are blind vias, so that raw water can only flow from the second fluid opening 1108 of the planar valve 10A into the eighth passageway 108A and further through the third passageway 103A, the third opening 1103, the second water inlet 521 to the second water treatment device 52 and into the second water treatment device 52, waste water generated by forward flushing the second water treatment device 52 flows from the second water outlet 522 of the second water treatment device 52 to the fourth opening 1104 of the planar valve 10A and further out of the drain opening 1013 through the fourth passageway 104A, the thirteenth opening 1013A, the fourth passageway 104A and the thirteenth opening 1012 of the planar valve 10A under water pressure. In other words, although the ninth passage 109A communicates with the sixth passage 106A, the tenth passage 1010A communicates with the first passage 101A, the water flow does not flow through the flow passages formed by them. Accordingly, when the planar valve 10A is in the second forward flushing operation position, the second passage 102A and the fifth passage 105A are blocked by the second fluid control surface 1220A of the movable valve plate 122A, thereby blocking water from flowing through the second opening 1102 and the fifth opening 1105 of the planar valve 10A; although the ninth passage 109A communicates with the sixth passage 106A, the tenth passage 1010A communicates with the first passage 101A, both the ninth passage 109A and the tenth passage 1010A are blind through-holes, and therefore, water flow is prevented from flowing through the first opening 1101 and the sixth opening 1106 of the planar valve 10A, so that water flow in the first water treatment device 51 and the third water treatment device 53 is prevented. In other words, although the ninth passage 109A communicates with the sixth passage 106A, the tenth passage 1010A communicates with the first passage 101A, the tenth passage 1010A of the plane valve 10A, the first opening 1101 of the plane valve 10A, the first water treatment device 51, the second opening 1102, the second passage 102A communicate in sequence, and the fifth passage 105A, the fifth opening 1105, the third water treatment device 53, the sixth opening 1106, the sixth passage 106A, and the ninth passage 109A communicate in sequence, the moving blade 122A blocks the flow of raw water to the first passage 101A, the second passage 102A, the fifth passage 105A, and the sixth passage 106A, thereby ensuring that only the second water treatment device 52 is positively rinsed.

It is noted that when the planar valve 10A is in the second positive flush operating position, the first channel 101A (or the flow channel formed by the tenth channel 1010A communicating with the first channel 101A), the second channel 102A, the fifth channel 105A, and the sixth channel 106A (or the flow channel formed by the ninth channel 109A communicating with the sixth channel 106A) are blocked by the movable valve plate 122A, respectively, such that the first opening 1101, the second opening 1102, the fifth opening 1105, and the sixth opening 1106 are blocked, that is, the first water treatment device 51 and the third water treatment device 53 are isolated from the water flow, so as to ensure that only the second water treatment device 52 is positively flushed, thereby preventing the generated sewage from flowing to the first water treatment device 51 and/or the third water treatment device 53 while increasing the strength of the water flow for positively flushing the second water treatment device 52. Thus, the second water treatment device 52 of the water treatment machine of the present utility model is solely positively flushed when the planar valve 10A is in the second positive flush operating position.

As shown in fig. 19F, 20H and 21F of the drawings, illustratively, when the plane valve 10A of the water treatment machine according to the embodiment of the present utility model is controlled to be in the second forward flushing operation position, raw water from the plane valve 10A flows into the second water treatment device 52 from the second water inlet 521 of the second water treatment device 52 under the action of water pressure, and then the second water treatment material 525 is flushed forward under the action of water pressure, and generated sewage is collected by the second central pipe 524 and flows out from the second water outlet 522 of the second water treatment device 52, flows to the fourth opening 1104 of the plane valve 10A under the action of water pressure, and then flows to the drain opening 11012A and is discharged through the fourth forward flushing flow path 7204A.

As shown in fig. 19G, 20I and 21G of the drawings, the flat valve 10A of the water treatment machine according to the embodiment of the present utility model further has a third positive washing operation position in which the eighth passage 108A of the flat valve 10A communicates with the fifth passage 105A when the flat valve 10A is in the third positive washing operation position, thereby forming a fifth positive washing passage 7205A communicating with the second fluid opening 1108 and the fifth opening 1105 of the valve body 11A of the flat valve 10A, respectively, and the twelfth passage 1012A communicates with the sixth passage 106A and the thirteenth passage 1013A, respectively, thereby forming a sixth positive washing passage 7206A communicating with the drain opening 11012A and the sixth opening 1106 of the valve body 11A of the flat valve 10A, respectively. As shown in fig. 16A to 16G, 19G and 21G of the drawings, further, when the plane valve 10A is in the third forward flushing operation position, the ninth passage 109A communicates with the second passage 102A, the tenth passage 1010A communicates with the fourth passage 104A, the eleventh passage 1011A communicates with the fifth passage 105A, and the first passage 101A and the third passage 103A are blocked by the second fluid control surface 1220A of the movable valve plate 122A, respectively. Thus, when the planar valve 10A is in the third forward flushing position, although the ninth passageway 109A is in communication with the second passageway 102A, the tenth passageway 1010A is in communication with the fourth passageway 104A, and the eleventh passageway 1011A is in communication with the fifth passageway 105A, as the first passageway 101A and the third passageway 103A are blocked by the second fluid control surface 1220A of the movable valve plate 122A, respectively, and the ninth passageway 109A, the tenth passageway 1010A, and the eleventh passageway 1011A are blind vias such that raw water can only flow from the second fluid opening 1108 of the planar valve 10A into the eighth passageway 108A, and further through the fifth passageway 105A, the fifth opening 1105 to the third water inlet 531 of the third water treatment device 53 and into the third water treatment device 53, forward flushing the waste water produced by the third water treatment device 53 flows from the third water outlet 532 of the third water treatment device 53 to the sixth opening 1106 of the planar valve 10A, and further through the twelfth opening 1013A, the thirteenth opening 1012, and the drain opening 1012 of the planar valve 10A, and the drain opening 1012A. In other words, although the ninth passage 109A communicates with the second passage 102A, the tenth passage 1010A communicates with the fourth passage 104A, and the eleventh passage 1011A communicates with the fifth passage 105A, water does not flow through the flow passages formed by them. Accordingly, when the planar valve 10A is in the third forward flushing operation position, the first channel 101A and the third channel 103A are blocked by the second fluid control surface 1220A of the movable valve plate 122A, thereby blocking water from flowing through the first opening 1101 and the third opening 1103 of the planar valve 10A; although the ninth passage 109A communicates with the second passage 102A, the tenth passage 1010A communicates with the fourth passage 104A, both the ninth passage 109A and the tenth passage 1010A are blind through-holes, and therefore, water flow is prevented from flowing through the second opening 1102 and the fourth opening 1104 of the planar valve 10A, so that water flow in the first water treatment device 51 and the second water treatment device 52 is prevented. In other words, although the ninth passage 109A communicates with the second passage 102A, the tenth passage 1010A communicates with the fourth passage 104A, the ninth passage 109A, the second passage 102A, the second opening 1102, the first water treatment device 51, the first opening 1101, the first passage 101A of the plane valve 10A communicate in sequence, and the tenth passage 1010A, the fourth passage 104A, the fourth opening 1104, the second water treatment device 52, the third opening 1103 and the third passage 103A of the plane valve 10A communicate in sequence, but since the movable valve plate 122A blocks the flow of raw water to the first passage 101A, the second passage 102A, the third passage 103A and the fourth passage 104A, it is ensured that only the third water treatment device 53 is flushed forward.

It is noted that when the plane valve 10A is in the third positive flushing operation position, the first channel 101A, the second channel 102A (or the flow channel formed by the communication between the ninth channel 109A and the second channel 102A), the third channel 103A and the fourth channel 104A (or the flow channel formed by the communication between the tenth channel 1010A and the fourth channel 104A) are blocked by the movable valve plate 122A, respectively, so that the first opening 1101, the second opening 1102, the third opening 1103 and the fourth opening 1104 are blocked, that is, the first water treatment device 51 and the second water treatment device 52 are isolated from the water flow, so that only the third water treatment device 53 is ensured to be positively flushed, and the generated sewage is prevented from flowing to the first water treatment device 51 and/or the second water treatment device 52 while the strength of the water flow for positively flushing the third water treatment device 53 is improved. Thus, the third water treatment device 53 of the water treatment machine of the present utility model is solely positively flushed when the planar valve 10A is in the third positive flush operating position.
