Detailed Description

In the related art gas water heater, when a user uses water, the gas water heater detects a water flow signal, the fan is started to clean the water before, waste gas in the water heater is discharged through the smoke tube, the air pressure switch detects the closing of the air pressure switch, the air valve is opened again to ignite and burn, and the water flows out through the water heater after being heated. The time from the boiling water of a user to the ignition and combustion of the water heater is about 3-5 s, and the time from the boiling water of the user to the constant-temperature hot water flowing out at the bathing place is generally 20-30 s.

However, when the gas water heater is used again after being suspended for a short time, that is, when a user uses water for a second time in a short time, because part of the water remains in the water outlet end of the water heater after the last water usage, hot water with a higher temperature flows out from the water outlet end of the water heater first. And because the above-mentioned need wait for fan to carry out preceding scavenging before ignition, and ignition burning needs 3 ~ 5s. Therefore, after the residual hot water flows out, the water with lower temperature flows out from the water outlet end of the water heater. After the ignition and combustion of the water heater are finished, water with the target water temperature can flow out from the water outlet end of the water heater.

Fig. 1 is a schematic view of a water heater provided in an embodiment of the present application, fig. 2 is a schematic view of another water heater provided in an embodiment of the present application, and arrows in fig. 1 and fig. 2 indicate a flow direction of liquid. Referring to fig. 1 and 2, the water heater 10 may have a water inlet end 101, a hot water end 102, and a water outlet end 103.

Illustratively, the inlet end 101 may have an inlet branch 104, the hot water end 102 may have an outlet branch 105, and the outlet end 103 may have an outlet manifold 107. A bypass branch pipe 106 can be communicated between the water inlet branch pipe 104 and the water outlet branch pipe 105. During operation of the water heater 10, cold water may be delivered through the water intake manifold 108. The output of the intake manifold 108 may be in communication with the intake branch 104 and the bypass branch 106, respectively. So that a part of cold water enters the water inlet end 101 of the water heater 10 through the water inlet branch pipe 104, a part of cold water is mixed with hot water flowing out from the water outlet branch pipe 105 through the bypass branch pipe 106, and the mixed water can flow out to a user through the water outlet header pipe 107.

However, in actual use, when the user uses water for the second time, if the amount of cold water mixed with the hot water in the hot water end 102 is increased, the temperature of the water flowing out of the water outlet end 103 of the water heater 10 can be lowered; reducing the amount of cold water flowing into the water heater 10 increases the heat exchange efficiency of the heat exchanger of the water heater 10, and thus increases the temperature of the water flowing out of the water outlet 103 of the water heater 10. Thus, when the user uses water for the second time, the temperature of the water flowing out from the water outlet end 103 of the water heater 10 is close to the target water temperature, so that the shower experience of the user is improved.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.

Example one

Fig. 3 is a schematic diagram of a one-inlet-two-outlet valve according to an embodiment of the present application. Referring to fig. 1-3, the one-in two-out valve provided in the embodiment of the present application may include a memory 61, a timer 62, a valve 9, and a controller 7. The memory 61 may be mounted to the water heater 10 and may record the last time the user finished using water. The timer 62 may be installed on the water heater 10 and may obtain the user's current water usage start time. At least a portion of the valve 9 may be disposed at the water inlet 101 and may regulate the flow of water into the water inlet 101. At least a part of the valve 9 can be disposed at the hot water end 102, and can adjust the flow of water flowing into the hot water end 102. The controller 7 may calculate a time interval between a current time when the user starts to use water and a last time when the user finishes using water, and may control the valve 9 to make the liquid flow into the water inlet 101 of the water heater 10 at a smaller flow rate and flow into the hot water end 102 of the water heater 10 at a larger flow rate when the time interval is smaller than a preset time period.

Specifically, the memory 61 can obtain the time of the timer 62 when the user closes the valve 9 of the outlet end 103 (or the shower head) of the water heater 10, and store the time as the last time the user used water. The memory 61 may be implemented by any type of volatile or non-volatile storage device or combination thereof, such as a static random access memory 61 (SRAM), an electrically erasable programmable read-only memory 61 (EEPROM), an erasable programmable read-only memory 61 (EPROM), a programmable read-only memory 61 (PROM), a read-only memory 61 (ROM), a magnetic memory 61, a flash memory 61, a magnetic or optical disk.

In addition, the timer 62 can obtain the current time when the user opens the valve 9 of the valve 9 (or the shower head) at the water outlet end 103 of the water heater 10, and the current time is the current water consumption starting time of the user. The timer 62 may be a timer that requires the user to periodically calibrate the time. The timer 62 may also return the acquired current time by sending the acquisition request message to the server. The current time may also be obtained from the network from the time.

In addition, the controller 7 can obtain the last water usage end time of the user sent by the memory 61 and the current water usage start time of the user sent by the timer 62 when the valve 9 of the valve 9 (or the shower head) of the outlet end 103 of the water heater 10 is opened by the user. The controller 7 may calculate the difference between the current water usage starting time of the user and the last water usage ending time of the user to obtain the time interval between two adjacent times of water usage of the user. The controller 7 may compare the calculated time interval with a preset time period, and if the time interval is smaller than the preset time period, the controller 7 may control the valve 9 to decrease the water flow flowing into the water inlet end 101 and increase the water flow flowing into the hot water end 102. If the time interval is greater than the preset time period, the water flow flowing into the water inlet end 101 and the water flow flowing into the hot water end 102 are kept unchanged.

It should be noted that the present application provides a one-in-two-out valve that can have at least two states. Wherein, the first state: the liquid flows into the water inlet end 101 of the water heater 10 at a relatively high flow rate and into the hot water end 102 of the water heater 10 at a relatively low flow rate. Namely, a state of large water inflow and small bypass amount. The second state: the liquid flows into the water inlet end 101 of the water heater 10 at a relatively small flow rate and into the hot water end 102 of the water heater 10 at a relatively large flow rate. Namely, a state of small water inflow and large bypass flow. The larger and smaller mentioned in this paragraph are compared for the two states. In other words, in the second state, the amount of water flowing into the water inlet end 101 of the water heater 10 is smaller than in the first state, and the amount of water flowing into the hot water end 102 of the water heater 10 is larger. When the user uses water for the second time, the one-inlet and two-outlet valves can operate in the second state for a period of time. After the one-in two-out valve operates for a period of time, the one-in two-out valve can be switched from the second state to the first state. The time period during which the one-in two-out valve operates in the second state may be a preset value. Alternatively, the one-in two-out valve can be switched from the second state to the first state after ignition heating.

Alternatively, the controller 7 may control the valve 9 to make the liquid flow into the water inlet end 101 of the water heater 10 at a smaller flow rate and flow into the hot water end 102 of the water heater 10 at a smaller flow rate when the operation state of the water heater 10 is stable, the heating state of the water heater 10 is at the maximum value, and the temperature of the water outlet end 103 of the water heater 10 is less than the preset temperature value.

Specifically, the one-in two-out valve provided by the present application may further have a third state: the liquid flows into the water inlet end 101 of the water heater 10 at a relatively small flow rate and into the hot water end 102 of the water heater 10 at a relatively small flow rate. Namely, a state of small water inflow and small bypass amount. When the water heater 10 operates in the first state for a period of time or hot water with stable temperature flows out from the water outlet end 103 of the water heater 10, and the proportional valve for regulating and controlling the fuel gas of the water heater 10 is adjusted to the maximum gear, however, when the water outlet temperature of the water heater 10 measured by the temperature detector arranged at the water outlet end 103 of the water heater 10 is lower than a preset temperature value, the one-inlet-two-outlet valve can be converted from the first state to the third state to increase the temperature of the water outlet end 103 of the water heater 10.

Referring to fig. 1, the valve 9 may be alternatively arranged in the following ways:

in one possible implementation manner, referring to fig. 1, the valve 9 may be multiple, each valve 9 may be an inlet/outlet valve 91, each inlet/outlet valve 91 may have a first water passage port and a water outlet port, and the inlet/outlet valve 91 may change the flow rate of the pipeline communicated with the openings by adjusting the opening degree of the water outlet port or the first water passage port. The valve 9 may include two one-in-one-out valves 91, wherein one-in-one-out valve 91 may be disposed in the bypass branch 106 to regulate the flow of the bypass branch 106; another in-out valve 91 may be provided on the inlet manifold 108 or the inlet branch 104. When an in-out valve 91 is disposed in the intake manifold 108 as shown in fig. 1, the in-out valve 91 can regulate the flow rate of the intake manifold 108. When an in-out valve 91 is provided in the inlet branch 104, the in-out valve 91 can regulate the flow rate of the inlet branch 104. Of course, the valve 9 may also comprise three one-in-one-out valves 91, and the bypass branch 106, the inlet branch 104 and the inlet manifold 108 may each be provided with one-in-one-out valve 91.

In another possible implementation, referring to fig. 2, the valve 9 may comprise at least one-in-two-out valve 92. The one-in-two-out valve 92 may have a first water passage port and two water outlet ports, and the one-in-two-out valve 92 may change the flow rate of the pipe communicating with the first water passage port and/or the water outlet ports by changing the opening degrees of the first water passage port and/or the water outlet ports. The first water inlet may be connected to the water inlet manifold 108, and the two water outlets may be connected to the water inlet branch 104 and the bypass branch 106, respectively.

The one-in two-out valve 92 can adjust the opening degree of two openings, and can also adjust the opening degree of three openings. In order to better control the flow rate, when the one in two out valve 92 can only adjust the opening degree of the two openings, a one in one out valve 91 is provided in the upstream line or the downstream line of the one in two out valve 92. For example, when the one in two out valve 92 can only adjust the opening degree of the two outlets, a one in one out valve 91 may be provided upstream of the one in two out valve 92. In the case where the one-in-two-out valve 92 can adjust only the opening degree of one outlet and one inlet, and one outlet is communicated with the water inlet branch pipe 104, a one-in-one-out valve 91 may be provided in the bypass branch pipe 106. Similarly, when the inlet and outlet valves can only adjust the opening degree of one outlet and one inlet, and one outlet is communicated with the bypass branch pipe 106, the inlet branch pipe 104 can be provided with one inlet and one outlet valve 91.

Fig. 4-28 show five configurations of the one-in two-out valve 92, and a possible implementation of the one-in two-out valve 92 will be described with reference to fig. 4-28. For convenience of description, in the embodiment of the present application, the direction indicated by the arrow X is the left end of the one-in two-out valve, and the other end is the right end of the one-in two-out valve; the direction indicated by an arrow Y is the front end of the one-inlet two-outlet valve, and the other end is the rear end of the one-inlet two-outlet valve; the direction indicated by the arrow Z is the upper end of the one-in two-out valve, and the other side is the lower end of the one-in two-out valve.

Fig. 4 is a front view of a two-in two-out valve 92 according to an embodiment of the present disclosure. Referring to fig. 4, the one-in-two-out valve 92 may include a valve body 1, and the valve body 1 may have a first water passage port 12 in an axial direction and a closed end 11, that is, one end of the valve body 1 in the axial direction is closed for mounting the driver 5; the other end of the valve body 1 in the axial direction has an opening to form a first water passage port 12. Exemplarily, in fig. 4, the valve body 1 may include a cylinder 19 and a cover plate 18. The cylinder 19 may be disposed in a vertical direction, and both the upper and lower ends of the cylinder 19 may have openings. The cover 18 can cover the upper opening of the cylinder 19 to form a closed end 11 at the upper end of the cylinder 19, and the lower end of the cylinder 191 forms the first water passage 12. Of course, the valve body 1 may have other structures for forming the first water passage port 12 and the closed end 11, and the embodiment of the present application is only illustrated by the structure of the cylinder 19 shown in fig. 4, and is not particularly limited.

Referring to fig. 4-28, the side wall of the valve body 1 between the first water passage port 12 of the valve body 1 and the closed end 11 of the valve body 1 may be provided with a second water passage port 13 and a bypass water outlet port 14, at least a part of the valve core assembly 2 is arranged in the valve body 1 and is movable relative to the valve body 1, and the valve core assembly 2 is used for changing the opening degrees of two of the second water passage port 13, the bypass water outlet port 14 and the first water passage port 12. Fig. 4 to 28 show the valve body 1 as an example in a space surrounded by the cylinder 19 and the cover plate 18.

The following description will be given by taking the example that the valve core assembly 2 shown in fig. 4 to 13 only changes the opening degrees of the second water passage opening 13 and the bypass water outlet 14, and the way of changing the second water passage opening 13 and the first water passage opening 12 or changing the bypass water outlet 14 and the first water passage opening 12 for the valve core assembly 2 can be obtained by referring to the way of changing the second water passage opening 13, the bypass water outlet 14 and the first water passage opening 12 (corresponding to fig. 14 to 28) of the valve core assembly 2 mentioned below, which is not described first.

Referring to fig. 4-13, the second water outlet 13 and the bypass water outlet 14 may be disposed on a side wall of the cylinder 19, the valve core assembly 2 may include a sleeve 22, and the sleeve 22 may change the opening degrees of the second water outlet 13 and the bypass water outlet 14 by rotating in the valve body 1 as shown in fig. 4-11, or the sleeve 22 may change the opening degrees of the second water outlet 13 and the bypass water outlet 14 by moving in the valve body 1 as shown in fig. 12 and 13.

Referring to fig. 4-11, in one example, the second water outlet 13 and the bypass water outlet 14 are disposed at different positions in the circumferential direction of the side wall of the cylinder 19. Fig. 4-11 show the second water outlet 13 on the left side of the cylinder 19 and the bypass water outlet 14 on the right side of the cylinder 19 as an example.

The sleeve 22 is rotatably disposed in the accommodating space formed by the cylinder 19 and the cover 18, and the rotation axis of the sleeve 22 can be disposed along the axis of the cylinder 19. I.e. the axis of rotation of the sleeve 22 is parallel or coincident with the axis of the barrel 19. The sleeve 22 may have a center hole 221 in the inside thereof, and the center hole 221 may be opposite to the first water passage port 12 of the valve body 1 and communicate with the first water passage port 12 of the valve body 1. The side wall of the sleeve 22 has a communication groove 222 communicating with the center hole 221, and the communication groove 222 is available to be opposed to the second water communication port 13 so that the communication groove 222 communicates with the second water communication port 13. The communication groove 222 may be used to oppose the bypass outlet 14 such that the communication groove 222 communicates with the bypass outlet 14.

Specifically, the communication groove 222 may communicate with the center hole 221 to communicate the second water passage opening 13, the bypass water outlet opening 14, and the first water passage opening 12 of the valve body 1. The communication groove 222 may be arranged in the following manners:

in one possible implementation, fig. 6 is an exploded view of the valve core assembly 2 shown in fig. 4, fig. 7 is a perspective longitudinal sectional view of the one-in-two-out valve 92 shown in fig. 4 in a first state, fig. 8 is a longitudinal sectional view of the one-in-two-out valve 92 shown in fig. 4 in a second state, and fig. 9 is a transverse sectional view of the one-in-two-out valve 92 shown in fig. 4 in the second state. Referring to fig. 6 to 9, the communication groove 222 may include at least a first communication groove 223 and a second communication groove 224. The first and

second communication grooves

223 and 224 may have a predetermined interval in the circumferential direction of the sleeve 22. The first communicating groove 223 may be used to communicate with the second water outlet 13, and the second communicating groove 224 may be used to communicate with the bypass water outlet 14.

The hollow arrows shown in fig. 7-9 are the flow direction of the liquid. Referring to fig. 7 to 9, the first water passage port 12 of the valve body 1 may be a first water passage port of a one-in two-out valve, and the first water passage port 12 of the valve body 1 may communicate with the water inlet manifold 108 through the first water pipe 15; the second water through opening 13 may be a second water through opening of a one-inlet two-outlet valve, the first water through opening 12 of the valve body 1, the central hole 221 of the sleeve 22, the first connecting groove 223 of the sleeve 22 and the second water through opening 13 may form a water inlet flow passage, and the second water through opening 13 may be communicated with the water outlet branch pipe 105 in fig. 2 through the second water pipe 16. The bypass water outlet 14 may be a bypass water outlet of a one-in two-out valve, the first water passage port 12 of the valve body 1, the central hole 221 of the sleeve 22, the second communicating groove 224 of the sleeve 22 and the bypass water outlet 14 may form a bypass flow passage, and the bypass water outlet 14 may be communicated with the bypass branch pipe 106 in fig. 2 through the bypass pipe 17.

Of course, the second water passage opening 13 may be a first water passage opening of a one-inlet two-outlet valve, and the first water passage opening 12 of the valve body 1 may be a second water passage opening of a one-inlet two-outlet valve. The second water passing opening 13, the first communicating groove 223 of the sleeve 22, the central hole 221 of the sleeve 22 and the first water passing opening 12 of the valve body 1 may form a water inlet flow passage, and the second water passing opening 13 may communicate with the water inlet manifold 108 in fig. 2. The bypass water outlet 14 may be a bypass water outlet of a one-inlet-two-outlet valve, the second water outlet 13, the central hole 221 of the sleeve 22, the second communicating groove 224 of the sleeve 22, and the bypass water outlet 14 may form a bypass flow channel, and the bypass water outlet 14 may communicate with the bypass branch pipe 106 in fig. 2 through the bypass pipe 17. Such a flow pattern will not be described in detail herein.

The first and second states of the one-in-two-out valve 92 will be described below by taking as an example the flow pattern shown in fig. 7-9, i.e., the second water passage opening 13 may be a second water passage opening of a one-in-two-out valve, the bypass water outlet 14 may be a bypass water outlet of a one-in-two-out valve, and the first water passage opening 12 of the valve body 1 may be a first water passage opening of a one-in-two-out valve.

Referring to fig. 7, when the one-in-two-out valve 92 is in the first state, the first communicating groove 223 may be directly opposite to the second water passing opening 13, and the directly opposite area is at a large value. That is, the area where the projection of the first communicating groove 223 on the side wall of the cylinder 19 in the radial direction of the cylinder 19 coincides with the second water passage port 13 is at a large value. When the one-in-two-out valve 92 is in the first state, the second communicating groove 224 may be opposed to the bypass water outlet 14, and the opposed area may be at a small value. That is, the area where the projection of the first communicating groove 223 on the side wall of the cylinder 19 in the radial direction of the cylinder 19 coincides with the second water communication port 13 is at a small value.

Referring to fig. 8 and 9, when the one-in two-out valve 92 is in the second state, the first communicating groove 223 may face the second water passing opening 13, and the facing area is at a smaller value. That is, the area where the projection of the first communicating groove 223 on the side wall of the cylinder 19 in the radial direction of the cylinder 19 coincides with the second water communication port 13 is at a small value. When the one-in-two-out valve 92 is in the second state, the second communicating groove 224 may be directly opposite to the bypass water outlet 14, and the directly opposite area may be at a larger value. That is, the area of the projection of the second communication groove 224 on the side wall of the cylindrical body 19 in the radial direction of the cylindrical body 19, which overlaps with the bypass water outlet 14, is large.

It should be noted that the area of the bypass water outlet 14 may be larger than the area of the second communicating groove 224 as shown in fig. 7 to 9, and of course, the area of the bypass water outlet 14 may be smaller than the area of the second communicating groove 224.

Referring to fig. 8, in order not to excessively affect the water inflow of the water heater 10 in the second state, i.e., in order to ensure the flow rate of the water inflow passage in the second state, the first communicating groove 223 may be lower than the second communicating groove 224 where it communicates with the second water-passing opening 13. That is, in the second state, only the liquid higher than the lower end of the second communication groove 224 flows into the bypass pipe 17 through the second communication groove 224 and the bypass water outlet 14.

Specifically, referring to fig. 9, in the second state, part of the first communicating groove 223 is shielded by the inner surface of the cylinder 19. A portion of the first communication groove 223 that is not shielded by the inner surface of the cylinder 19 may be opposite to and communicate with the second water communication port 13. Referring to fig. 8, the lower end of the first communication groove 223, which is partially not blocked by the inner surface of the cylinder 19, may be lower than the second communication groove 224. The upper end of part of the first communication groove 223 may be higher than the lower end of the second communication groove 224 and lower than the upper end of the second communication groove 224 as shown in fig. 8. Of course, the upper end of the part of the first communication groove 223 may be lower than the lower end of the second communication groove 224.

In order to realize that the portion of the first communicating groove 223 which is not covered by the inner surface of the cylinder 19 in the second state, that is, the portion of the first communicating groove 223 opposite to the second water passage opening 13 is lower than the second communicating groove 224, the shape of the first communicating groove 223 may be set in the embodiment of the present application:

referring to fig. 5, alternatively, the highest point of at least a portion of the first connecting grooves 223 may be gradually inclined upward in a preset direction. The predetermined direction may be a rotational direction in which the sleeve 22 rotates from the first state to the second state. Illustratively, the arrow W in fig. 5 indicates a counterclockwise direction. Referring to fig. 2, the sleeve 22 is rotatable in the W direction, i.e., counterclockwise, from the first state to the second state. An upper edge line of the first communicating groove 223 may be gradually inclined upward in a counterclockwise direction.

In order to increase the opening size of the first communicating groove 223, at least a portion of the first communicating groove 223 may be disposed at an upper portion of the sidewall of the sleeve 22, and at least a portion of the first communicating groove 223 may be disposed at a lower portion of the sidewall of the sleeve 22. For example, the left edge line of the first connecting groove 223 in fig. 5 may have an arc shape, and the center of the left edge line may be located at the middle right side of the left edge line. That is, the first communicating groove 223 may be a figure symmetrical with respect to the central axis plane of the sleeve 22, and the center of the left side edge line may be located on the central axis plane of the sleeve 22. The central axial plane of the sleeve 22 may be parallel to the bottom plane of the sleeve 22, and the distance from the upper end surface of the sleeve 22 to the central axial plane is equal to the distance from the lower end surface of the sleeve 22 to the central axial plane.

Referring to fig. 7 and 8, alternatively, in order to make the sleeve 22 rotate in the cylinder 19 more stably, the outer surface of the sidewall of the sleeve 22 may contact the inner surface of the cylinder 19, and the outer surface of the sleeve 22 may be fitted to the inner surface of the cylinder 19. In order to bring the outer surface of the side wall of the sleeve 22 into contact with the inner surface of the first water pipe 15, the upper end surface of the sleeve 22 may be higher than the highest end of both the second water outlet 13 and the bypass water outlet 14. The lower end face of the sleeve 22 may be lower than the lowest end of both the second water outlet 13 and the bypass water outlet 14.

With continued reference to fig. 5-8, to rotate sleeve 22, sleeve 22 may optionally include side walls and a top wall, to which a connecting rod 21 may be secured to the top wall of sleeve 22. The connecting rod 21 can pass through the cover plate 18 and be connected to the drive 5 arranged outside the cover plate 18. The actuator 5 can be rotated by driving the connecting rod 21 to rotate the sleeve 22. The drive 5 may be in communicative connection with the above mentioned controller 7. The driver 5 can be a motor, the motor can be provided with a motor shaft, the motor shaft can be directly connected with the connecting rod 21 in a welding mode, an interference fit mode, a coupling mode and the like, and the motor shaft can also be indirectly connected with the connecting rod 21 through a speed reducer and the like.

In order to make the connecting rod 21 rotate stably, the cover plate 18 and the cylinder 19 form a containing space for containing the shaft sleeve 4. The outer surface of the sleeve 4 may be fixed to the inner surface of the cylinder 19, and the upper surface of the sleeve 4 may abut against the cover plate 18. The connecting rod 21 is passed through the bushing 4 and is rotatable relative to the bushing 4. The outer surface of the sleeve 4 may be provided with a groove which may receive a sealing ring 8 with the inner surface of the cylinder 19 to effect a seal between the sleeve 4 and the inner surface of the cylinder 19.

Referring to fig. 7 and 8, to achieve axial retention of the sleeve 22 in the barrel 19, the top wall of the sleeve 22 may abut the lower surface of the sleeve 4. The lower end of the cylinder 19 can be fixed with a first water pipe 15, the first water pipe 15 can be coaxially arranged with the cylinder 19, and the diameter of the first water pipe 15 can be smaller than that of the cylinder 19, so that the inner surface of the first water pipe 15 can be closer to the axis of the cylinder 19 than the inner surface of the cylinder 19, and a limiting step surface for limiting the lower end surface of the sleeve 22 is formed.

In the case of using a rotary motor, the connecting rod 21 is movable while rotating relative to the valve body 1. The end of the connecting rod 21 extending out of the valve body 1 is provided with a tooth structure, the rotating shaft of the rotating motor is provided with an inner gear ring, the tooth structure is arranged in the inner gear ring in a sliding manner and is meshed with the inner gear ring, and the tooth structure and the gear ring structure are matched to meet the rotating requirement of the connecting rod 21 on one hand and meet the sliding movement requirement of the connecting rod 21 in the rotating process on the other hand. Correspondingly, an internal thread is arranged in the shaft sleeve 4, an external thread is arranged on the connecting rod 21, and the connecting rod 21 is in threaded connection with the shaft sleeve 4.

Fig. 10 is a sectional view of a second one-in-two-out valve 92 provided in the embodiment of the present application in a first state, and fig. 11 is a sectional view of the one-in-two-out valve 92 shown in fig. 10 in a second state. Referring to fig. 10 and 11, in another example, the second water outlet 13 and the bypass water outlet 14 are disposed at different positions in the axial direction of the side wall of the cylinder 19. Fig. 10 and 11 show an example in which the second water passage 13 is provided at the lower end of the cylinder 19 and the bypass water outlet 14 is provided at the upper end of the cylinder 19.

The sleeve 22 is slidably disposed in the accommodating space formed by the cylinder 19 and the cover plate 18, and the sleeve 22 can slide along the axial direction of the cylinder 19. The sleeve 22 may have a center hole 221 in the inside thereof, and the center hole 221 may be opposite to the first water passage port 12 of the valve body 1 and communicate with the first water passage port 12 of the valve body 1. The sidewall of the sleeve 22 may have a first communicating groove 223 and a second communicating groove 224 communicating with the central hole 221. The first communicating groove 223 and the second communicating groove 224 may have a predetermined interval in the axial direction of the sleeve 22. The first communicating groove 223 may be used to communicate with the second water outlet 13, and the second communicating groove 224 may be used to communicate with the bypass water outlet 14.

Additionally, the sleeve 22 may include a top wall and a side wall. The top wall of the sleeve 22 may be connected with a connecting rod 21, and the connecting rod 21 may pass through the cover plate 18 and may move in the axial direction of the cylinder 19 relative to the cover plate 18. The portion of the connecting rod 21 outside the cover plate 18 can be connected to the actuator 5. The driver 5 may be communicatively connected to the controller 7 mentioned above. The driver 5 can be a linear motor, an air cylinder and other devices capable of outputting axial force. The driver 5 may also be a rotary motor and a conversion mechanism that converts torque into linear motion.

In another possible implementation manner of the communication groove 222, fig. 12 is a transverse cross-sectional view of a third one-in two-out valve provided in the embodiment of the present application in a first state, and fig. 13 is a transverse cross-sectional view of the one-in two-out valve shown in fig. 10 in a second state. Referring to fig. 12 and 13, the cross-sectional shape of at least a portion of the sleeve 22 may be semi-annular. The inner surface of the sleeve 22 may be formed with a center hole 221 communicating with the first water passage port 12, and the sleeve 22 may have a first end surface 225 and a second end surface 226 in the circumferential direction, that is, one end in the circumferential direction of the sleeve 22 may have the first end surface 225 and the other end in the circumferential direction of the sleeve 22 may have the second end surface 226. A communication groove 222 (not labeled in fig. 12 and 13) may also be formed between the first and second end faces 225, 226 of the sleeve 22.

Wherein a circumference of an inner surface between the second end of the second water outlet 13 of the barrel 19 and the first end of the bypass water outlet 14 of the barrel 19 may be smaller than a circumference of an outer surface of the sleeve 22 (i.e., a circumference between the first end face 225 of the sleeve 22 and the second end face 226 of the sleeve 22).

Specifically, the outer surface of the sleeve 22 may engage the inner surface of the barrel 19 and may rotate relative to the inner surface of the barrel 19. When the sleeve 22 is in the first state as shown in fig. 12, the sleeve 22 may block a small part of the second water passage opening 13 or not block the second water passage opening 13, that is, a projection of the sleeve 22 on the cylinder 19 along a radial direction of the cylinder 19 does not fall into the second water passage opening 13 or only falls into the second water passage opening 13 at a small part, so that an opening degree of the second water passage opening 13 is large; the sleeve 22 may block at least part of the bypass outlet 14 such that the bypass outlet 14 is less open.

When the sleeve 22 is in the second state as shown in fig. 13, the sleeve 22 may block at least part of the second water through opening 13, that is, a projection of the sleeve 22 on the cylinder 19 along the radial direction of the cylinder 19 at least partially falls in the second water through opening 13, so that the opening degree of the second water through opening 13 is smaller; the sleeve 22 may block a small part of the bypass water outlet 14 or not block the bypass water outlet 14, that is, a projection of the sleeve 22 on the cylinder 19 along a radial direction of the cylinder 19 does not fall within the bypass water outlet 14 or falls only a small part within the bypass water outlet 14, so that the bypass water outlet 14 has a larger opening degree.

In another embodiment, the control of the bypass water outlet 14 for the sleeve 22 sliding in the cylinder 19 may also adopt the mode of fig. 29 and fig. 30, that is, the sleeve 22 is arranged at one side of the bypass pipe 17 and used for adjusting the opening degree of the bypass water outlet 14 in the bypass pipe 17.

Specifically, as shown in fig. 29, in the first state, the second water outlet 13 is opened to the maximum, and the bypass water outlet 14 is opened to the minimum in the closed state. As shown in fig. 30, as the driver 5 drives the sleeve 22 to move downwards in the cylinder 19, the upper edge of the sleeve 22 gradually exposes the bypass water outlet 14, so as to adjust the opening degree of the bypass water outlet 14. The path of the water flow is indicated by the dashed arrows in fig. 29 and 30.

Wherein, a clapboard (not marked) is arranged in the bypass pipe, a bypass water outlet 14 is arranged on the clapboard, the sleeve 22 is positioned at one side of the clapboard, and the sleeve 22 is used for opening and closing the bypass water outlet in the sliding process of the valve body. The baffle blocks the orifice of the bypass pipe 15 and reserves the bypass water outlet 14, and the sleeve 22 moves up and down on one side of the baffle to realize the adjustment of the opening degree of the bypass water outlet 14.

In addition, in order to adjust the opening degree of the second water passing port 13, the connecting rod 21 penetrates through the sleeve 22, and the end of the connecting rod 21 is provided with a plug 24, and the plug 24 is arranged opposite to the second water passing port 13. In the process that the connecting rod 21 drives the sleeve 22 to move up and down, the plug 24 is close to or far away from the second water through opening 13, and the opening degree of the second water through opening 13 is changed.

The following describes a one-in two-out valve capable of changing three openings with reference to fig. 14 to 22, and the use of a one-in two-out valve capable of changing three openings can have an advantage of changing a wide range of flow rates with a small range of actuation.

The above-provided one in two out valve capable of changing two openings and the below-provided one in two out valve capable of changing three openings may be the same point: the valve core assembly 2 can comprise a sleeve 22, and the sleeve 22 can change the opening degrees of the second water outlet 13 and the bypass water outlet 14 in a manner of rotating in the cylinder 19. The difference lies in that: the valve core assembly 2 can further comprise a connecting rod 21, and the connecting rod 21 can pass through the first water through port 12 of the valve body 1 and can change the opening degree of the first water through port 12 of the valve body 1 in a sliding mode along the axis of the cylinder 19.

Fig. 19 is a longitudinal sectional view of the one-in-two-out valve 92 shown in fig. 14 in a first state, and fig. 21 is a longitudinal sectional view of the one-in-two-out valve 92 shown in fig. 14 in a second state. Referring to fig. 19 and 21, the connection rod 21 may be inserted through the cylinder 19 in an axial direction of the cylinder 19. Part of the connecting rod 21 may be located outside the cover plate 18 to connect with the driver 5; a portion of the connecting rod 21 may be located in the cylinder 19 and pass through the first water passage port 12 of the valve body 1, and a flow passage for liquid to flow through may be formed between an outer surface of the portion of the connecting rod 21 and an inner surface of the first water passage port 12 of the valve body 1. The size of the flow passage may be varied during axial movement of the connecting rod 21 along the barrel 19.

For example, in fig. 19 and 21, the connecting rod 21 may be fixed with the plug 24, and the inner surface of the first water passage port 12 of the valve body 1 may be fixed with the annular water stop 32, that is, the water stop 32 may have a central hole 221 inside. During the change of the connecting rod 21 from the first state to the second state, the flow passage of the downward movement of the valve body 1 is reduced. To accomplish this trend, at least one of the outer surface of the plug 24 and the inner surface of the water dam stage 32 is beveled. In an example, referring to fig. 19 and 21, the central hole 221 of the water blocking platform 32 may include a reverse tapered section, and a diameter of the reverse tapered section may be gradually reduced in a direction approaching the end surface of the first water passage opening 12 of the valve body 1 (i.e., the lower end surface of the barrel 19 in fig. 19 and 21), so that a distance between the plug 24 and the central hole 221 is gradually reduced in a process of gradually approaching the end surface of the first water passage opening 12 of the valve body 1. Alternatively, the center hole 221 may further include a cylindrical section that may be closer to the end face of the first water passage port 12 of the valve body 1 than the reverse taper section, and the diameter of the cylindrical section may be equal to the minimum diameter of the reverse taper section. In the second state, a portion of the plug 24 may be located within the cylindrical section to extend the length of the smaller flow path.

In another example, the plug 24 may be coaxial with the connecting rod 21, and at least a portion of the plug 24 may have a diameter gradually decreasing in a direction approaching the end surface of the first water passage port 12 of the valve body 1. In the first state, the smaller diameter end of the plug 24 may be positioned within the central aperture 221 of the water stop 32. In the transition from the first state to the second state, the larger diameter end of the plug 24 gradually falls into the central hole 221 of the water stop 32, so as to gradually reduce the distance between the plug 24 and the central hole 221 of the water stop 32.

Fig. 22 is a transverse sectional view of the mounting plate 31 shown in fig. 21, and referring to fig. 21 and 22, in order to stably move the connecting rod 21 relative to the valve body 1, optionally, the mounting plate 31 may be further fixed in the first water passage port 12 of the valve body 1, the mounting plate 31 may have a limit hole for passing the connecting rod 21 therethrough, and a part of the connecting rod 21 may be slidably disposed in the limit hole. In addition, a flow passage for liquid to flow through may be provided between the mounting plate 31 and the barrel 19 or the water guard 32.

To simplify the control, an actuator 5 can be used to move the connecting rod 21 and to rotate the sleeve 22. Referring to fig. 19 and 21, the connecting rod 21 may alternatively include a first end and a second end, and the first end of the connecting rod 21 may be threadedly connected to the valve body 1, so that when the driver 5 drives the connecting rod 21 to rotate, the connecting rod 21 may move axially along the connecting rod 21 in a rotating manner. The second end of the connecting rod 21 may be connected to the sleeve 22 so that the connecting rod 21, when in motion, drives the sleeve 22 in rotation. Of course, in order to facilitate the change of the first water passage port 12 of the valve body 1 by the connecting rod 21, the second end of the connecting rod 21 may be passed through the sleeve 22 and the first water passage port 12 of the valve body 1 may be passed through.

In addition, in order to make the diameter of the connecting rod 21 smaller than that of the cylinder 19, the setting of the sleeve 22 is facilitated. Optionally, the sleeve 4 may be accommodated in an accommodating space formed by the cylinder 19 and the cover plate 18. The sleeve 4 may include a mounting portion 41. The outer surface of the mounting portion 41 may be fixed to the inner surface of the cylinder 19, and the interior of the mounting portion 41 may have a threaded hole to which the first end of the connecting rod 21 is threadedly coupled. In order to prevent the liquid in the accommodating space from leaking, a sealing ring 8 may be provided between the mounting portion 41 and the inner surface of the cylinder 19. In addition, in order to facilitate the rotation of the sleeve 22 in the cylinder 19, referring to fig. 19 and 21, the bushing 4 may further include a stopper portion 42, the stopper portion 42 may be disposed coaxially with the mounting portion 41, and the stopper portion 42 may be located below the mounting portion 41. The diameter of the stopper portion 42 may be smaller than the diameter of the mounting portion 41 so that there may be a certain distance between the stopper portion 42 and the inner surface of the cylinder 19. The sleeve 22 can be accommodated within this spacing. That is, the sleeve 22 may be sleeved outside the limiting portion 42 and may be embedded inside the cylinder 19 so as to limit the radial displacement of the sleeve 22.

In addition, the connecting rod 21 can drive the sleeve 22 to move in the following possible ways:

in one of the possible implementations, the sleeve 22 is movable relative to the connecting rod 21 as shown in fig. 15-21. Referring to fig. 15 to 21, the side wall of the connecting rod 21 may be fixed with a mounting rod 23, and the mounting rod 23 may be disposed in a radial direction of the connecting rod 21. The sidewall of the sleeve 22 may have a mounting groove 227 that mates with the mounting rod 23. Since the connecting rod 21 moves while rotating, the mounting groove 227 is approximately L-shaped, and the mounting groove 227 may have an opening at one end.

During the rotation of the connecting rod 21 with the sleeve 22 via the mounting rod 23 and the mounting groove 227, the connecting rod 21 can have a first position as shown in fig. 15 and a second position as shown in fig. 17. Referring to fig. 16, the mounting groove 227 may include a first section 2271 and a second section 2272, the first section 2271 may extend in an axial direction of the sleeve 22, the second section 2272 may have an end extending in a circumferential direction of the sleeve 22, and an end of the second section 2272 facing away from the first section 2271 is open.

Referring to fig. 19, in the first state, the second water passage opening 13 is at a large opening degree, the bypass water outlet opening 14 is at a small opening degree, and the first water passage opening 12 of the valve body 1 is at a large opening degree. In the process of moving the connecting rod 21 from fig. 19 to fig. 21, the connecting rod 21 can rotate clockwise and descend, and the mounting rod 23 is first in the first position shown in fig. 15, so that the connecting rod 21 can drive the sleeve 22 to descend while rotating, and the opening degree of the bypass water outlet 14 shown in fig. 20 and 21 is formed. When the lower end surface of the sleeve 22 abuts against the stopper 42 in the valve body 1, the mounting rod 23 can be rotated clockwise from the first position shown in fig. 15, and slid out of the mounting groove 227 from the opening of the second portion 2272 of the mounting groove 227. After the mounting rod 23 is moved from the second position shown in fig. 17 to the first position shown in fig. 15 to form the position of the plug 24 shown in fig. 20.

Similarly, during the rotation of the connecting rod 21 from fig. 21 to fig. 19, the connecting rod 21 can be raised while rotating counterclockwise, and the mounting rod 23 is caused to move from the second position shown in fig. 17 to the first position shown in fig. 15. After the mounting rod 23 moves to the first position, the connecting rod 21 continues to rotate counterclockwise, so as to drive the sleeve 22 to rotate counterclockwise and rise, so as to form the opening degree of the bypass water outlet 14 shown in fig. 18 and 19.

It should be noted that the above-mentioned limiting portion 42 can limit the lowest position of the rotation of the sleeve 22, so that the sleeve 22 is supported by the limiting portion 42 when the mounting rod 23 is disengaged from the mounting groove 227 of the sleeve 22. In fig. 19 and 21, the upper end surface of the water baffle table 32 may be higher than the second drainage port 13 so as to support the sleeve 22.

The one-in two-out valve capable of changing the opening degrees of the three openings will be described below with reference to fig. 23 to 28, and the use of the one-in two-out valve capable of changing the opening degrees of the three openings can have an advantage of changing a wide range of flow rates with a small range of actuation.

The one-inlet two-outlet valve comprises a valve body 1 and a valve component 2. The valve body is provided with a first water through port 12, a second water through port 13 and a bypass water outlet 14.

The valve core assembly 2 comprises a connecting rod 21 and a sleeve 22, wherein a plug 24 is arranged at one end of the connecting rod 21, and the sleeve 22 is sleeved on the connecting rod 21 and can intermittently rotate along with the connecting rod 21.

Wherein the connecting rod 21 is rotatably disposed on the valve body 1 and is further movable relative to the valve body 1 during rotation, the sleeve 22 and the plug 24 are located in the valve body 1, the sleeve 22 is disposed on one side of the bypass water outlet 14 and is used for adjusting the opening degree of the bypass water outlet 14, and the plug 24 is disposed opposite to the second water outlet 13 and is used for adjusting the opening degree of the second water outlet 13.

Specifically, the valve body 1 may include a cylinder 19 and a cover plate 18. The cylinder 19 may be disposed in a vertical direction, and both upper and lower ends of the cylinder 19 may have openings. The cover plate 18 can cover the opening of the cylinder 19 above to form a closed end 11 at the upper end of the cylinder 19 and a second water through opening 13 at the lower end of the cylinder 191. The side wall of the valve body 1 between the second water passage opening 13 of the valve body 1 and the closed end 11 of the valve body 1 can be provided with a first water passage opening 12 and a bypass water outlet opening 14.

During use, the connecting rod 21 rotates to drive the plug 24 to be close to or far away from the second water outlet 13 to change the opening degree of the second water outlet, and meanwhile, in the rotating process of the connecting rod 21, the connecting rod 21 can also drive the sleeve 22 to rotate in the valve body 1, so that the opening degree of the bypass water outlet 14 can be changed.

Likewise, the sleeve 22 has a central hole 221 formed therein, the central hole 221 is disposed opposite to the second water outlet 13, and a first communication groove 223 is formed in a side portion of the sleeve 22 for communicating with the central hole 221, and the first communication groove 223 is for communicating with the bypass water outlet 14.

In the process of adjusting the bypass water outlet 14, the overlapping area of the first connecting groove 223 and the bypass water outlet 14 will change, and a larger overlapping area will increase the opening degree of the bypass water outlet 14, whereas a smaller overlapping area will decrease the opening degree of the bypass water outlet 14. Correspondingly, the sleeve 22 can shield at least part of the bypass water outlet 14 in the process of rotating along with the connecting rod 21 so as to change the opening degree of the bypass water outlet 14.

Preferably, the sleeve 22 can also change the opening degree of the first water passage opening 12 and the bypass water outlet opening 14 by rotating in the cylinder 19. Specifically, a second communication groove 224 is further provided in the side wall of the sleeve 22, and the first water passage port 12 communicates with the center hole 221 through the second communication groove 224.

During the first water passage port 12, the overlapping area of the second communication groove 224 with the first water passage port 12 changes, and a larger overlapping area increases the opening degree of the first water passage port 12, whereas a smaller overlapping area decreases the opening degree of the first water passage port 12. Correspondingly, during the rotation of the sleeve 22 following the connecting rod 21, the sleeve 22 can also shield at least part of the first water through opening 12 to change the opening of the first water through opening 12.

In addition, fig. 23 to 28 show that the lower end surface of the bypass water outlet 14 is higher than the upper end surface of the first water passage port 12, that is, the first water passage port 12 and the bypass water outlet 14 are arranged in a staggered manner in the axial direction of the sleeve 22; referring to fig. 24, 26, and 28, the sleeve 22 has a first communicating groove 223 and a second communicating groove 224 disposed one above another in the axial direction of the sleeve 22.

The sleeve 22 may be fixed to the connecting rod 21 as shown in fig. 23-28. The second end of the connecting rod 21 may pass through the bushing 22 and may be fixed with the bushing 22. The fixing mode between the connecting rod 21 and the sleeve 22 can be non-detachable connection such as welding, bonding and the like, and can also be detachable connection such as clamping connection, threaded connection and the like. For example, in fig. 23 and 24, the sidewall of the sleeve 22 may be provided with a mounting groove 227, and the mounting groove 227 may have a downward opening. The side wall of the connecting rod 21 may be fixed with a mounting rod 23, and the mounting rod 23 may be snap-coupled with the mounting groove 227. For stable connection between the connecting rod 21 and the bushing 22, the mounting rods 23 may have at least two, and a plurality of mounting rods 23 may be uniformly distributed at the outer circumference of the connecting rod 21. Fig. 23 and 24 illustrate two mounting rods 23 as an example.

Illustratively, the connecting rod 21 is fixed with a plug 24, and the inner surface of the second water through opening 13 of the valve body 1 is fixed with an annular water retaining platform 32. During the process of changing the connecting rod 21 from the first state to the second state, the plug 24 moves downward to reduce the water flow cross-sectional area of the second water through opening 13, so that the flow passage is reduced.

To accomplish this trend, at least one of the outer surface of the plug 24 and the inner surface of the water dam stage 32 is beveled. Namely, the second water through opening 13 is provided with an annular water blocking platform 32, the water blocking platform 32 is provided with a first inclined surface to form a taper hole structure, and the plug is provided with a second inclined surface to form a taper hole structure.

Specifically, the central through hole of the water blocking platform 32 may include an inverted cone section to form a tapered hole structure, and a diameter of the inverted cone section may gradually decrease in a direction approaching the end surface of the second water passing opening 13 of the valve body 1, so that a distance between the plug 24 and the central hole 221 gradually decreases in a process that the plug 24 gradually approaches the end surface of the second water passing opening 13 of the valve body 1. Optionally, the central through hole of the water baffle table 32 may further include a cylindrical section, which may be closer to the end surface of the second water through opening 13 of the valve body 1 than the reverse taper section, and the diameter of the cylindrical section may be equal to the minimum diameter of the reverse taper section. In the second state, a portion of the plug 24 may be located within the cylindrical section to facilitate extending the length of the smaller flow path.

In another example, the plug 24 may be coaxial with the connecting rod 21, and at least a portion of the plug 24 may have a diameter gradually decreasing in a direction approaching the end surface of the second water passage opening 13 of the valve body 1 to form a conical head structure. In the first position, the smaller diameter end of the plug 24 is positioned within the central through-hole of the water stop 32. In the process of changing from the first state to the second state, the end with the larger diameter of the plug 24 gradually falls into the central through hole of the water stop 32, so as to gradually reduce the distance between the plug 24 and the central through hole of the water stop 32.

In order to make the connecting rod 21 move stably relative to the valve body 1, optionally, a mounting plate 31 may be further fixed in the second water through opening 13 of the valve body 1, the mounting plate 31 may have a limiting hole for the connecting rod 21 to pass through, and a part of the connecting rod 21 may be slidably disposed in the limiting hole. In addition, a flow passage for liquid to flow through may be provided between the mounting plate 31 and the barrel 19 or the water stop 32.

To simplify the control, an actuator 5 can be used to move the connecting rod 21 and to rotate the sleeve 22. Referring to fig. 19 and 21, the connecting rod 21 may alternatively include a first end and a second end, and the first end of the connecting rod 21 may be threadedly connected to the valve body 1, so that when the driver 5 drives the connecting rod 21 to rotate, the connecting rod 21 may move axially along the connecting rod 21 in a rotating manner. The second end of the connecting rod 21 may be connected to the sleeve 22 so that the connecting rod 21, when in motion, drives the sleeve 22 in rotation. Of course, in order to facilitate the change of the second water passage opening 13 of the valve body 1 by the connecting rod 21, the second end of the connecting rod 21 may pass through the sleeve 22 and may pass through the second water passage opening 13 of the valve body 1.

In addition, in order to make the diameter of the connecting rod 21 smaller than that of the cylinder 19, the setting of the sleeve 22 is facilitated. Optionally, the sleeve 4 may be accommodated in an accommodating space formed by the cylinder 19 and the cover plate 18. The bushing 4 may include a mounting portion 41. The outer surface of the mounting portion 41 may be fixed to the inner surface of the cylinder 19, and the interior of the mounting portion 41 may have a threaded hole to which the first end of the connecting rod 21 is threadedly coupled. In order to prevent the liquid in the accommodating space from leaking, a sealing ring 8 may be provided between the mounting portion 41 and the inner surface of the cylinder 19. In addition, in order to facilitate the rotation of the sleeve 22 in the cylinder 19, referring to fig. 19 and 21, the bushing 4 may further include a stopper portion 42, the stopper portion 42 may be disposed coaxially with the mounting portion 41, and the stopper portion 42 may be located below the mounting portion 41. The diameter of the stopper portion 42 may be smaller than the diameter of the mounting portion 41 so that there may be a certain distance between the stopper portion 42 and the inner surface of the cylinder 19. The sleeve 22 can be accommodated within this spacing. That is, the sleeve 22 may be sleeved outside the limiting portion 42 and may be embedded inside the cylinder 19, so as to limit the radial displacement of the sleeve 22.

It is to be noted that the hollow arrows shown in fig. 19, 21, 26, and 28 indicate the flow direction of the liquid. Fig. 19, 21, 26 and 28 show examples in which the second water passage port 13 may be a first water passage port of a one-in two-out valve, the first water passage port 12 of the valve body 1 may be a second water passage port of a one-in two-out valve, and the bypass water outlet port 14 may be a bypass water outlet port of a one-in two-out valve. Of course, the second water through opening 13 may also be a second water through opening of a one-inlet two-outlet valve, the bypass water outlet 14 may also be a bypass water outlet of a one-inlet two-outlet valve, and the first water through opening 12 of the valve body 1 may be a first water through opening of a one-inlet two-outlet valve.

It should be noted that the above-mentioned structure of the one inlet/two outlet valve may also be in a third state, and the third state may be a state between the first state and the second state.
