In order to simplify the structure of the waste valve, the present invention proposes a new waste valve, please refer to fig. 1, fig. 1 is a semi-sectional view of an embodiment of the waste valve of the present invention.
Referring to fig. 3, the waste water valve 10 is applied to a water purifying system 100, and is disposed in communication with a waste water port of a membrane filter core 20 of the water purifying system 100 through a pipeline, wherein the waste water valve 10 includes a main pipe 11, a floating member 12 and other components.
The main pipe 11 may be a linear pipe or a curved pipe, and is not particularly limited herein, and may be provided according to actual situations. The main pipe 11 has a water inlet port 111 and a water outlet port 112, the water inlet port 111 of the main pipe 11 communicates with the water outlet port of the membrane cartridge 20 of the water purification system 100 through a pipe, and the water outlet port 112 of the main pipe 11 communicates with an external water pipe. The water outlet 112 of the main pipe 11 is provided with a first water outlet and a second water outlet, the aperture of the first water outlet is 0.35-1.05mm, and the aperture of the second water outlet is far larger than that of the first water outlet, so that most of water in the main pipe 11 is discharged from the second water outlet when the main pipe 11 is connected with water, and only a small part of water is discharged from the first water outlet.
The floating member 12 is movably installed in the main pipe 11, that is, the floating member 12 can float in the main pipe 11 when being impacted by water. It should be noted that, the radial cross section of the floating member 12 along the main pipe 11 is larger than the aperture of the second water outlet, and the radial cross section of the floating member 12 along the main pipe 11 is smaller than the aperture of the main pipe 11, so as to ensure that the floating member 12 can move in the main pipe 11 and also can seal the second water outlet.
When the waste water valve 10 is assembled with the membrane filter core 20, the waste water valve 10 is installed along the vertical direction, and the water outlet port 112 of the waste water valve 10 is positioned above the water inlet port 111, so that the openings of the first water outlet and the second water outlet of the water outlet port 112 are ensured to be upward; the float 12 installed in the main pipe 11 stays at the water inlet port 111 of the main pipe 11 under its own weight.
When the floating member 12 is positioned at the water inlet 111 of the main pipe 11, the floating member 12 does not completely block the water inlet 111 of the main pipe 11.
Referring to fig. 2, when the water purification system 100 starts to produce pure water, external raw water is driven into the membrane filter core 20 by the water pump 30, and the water pressure of the raw water is increased by the driving of the water pump 30, so that the water pressure of the whole water purification system 100 is increased, and the water pressure of the wastewater discharged from the wastewater outlet of the membrane filter core 20 is sufficiently high. Because the aperture of the second water outlet is greater than the aperture of the first water outlet, when the main pipeline 11 is filled with water, water can flow out from the second water outlet with larger aperture preferentially, when the water pressure of the wastewater reaches the preset water pressure, namely the water pressure capable of jacking up the floating piece 12, the floating piece 12 can be jacked up by the high-pressure wastewater and moves to the water outlet 112 of the main pipeline 11 to plug the second water outlet, so that the water in the main pipeline 11 can only be discharged from the first water outlet with smaller aperture, the flow limitation of the waste water outlet of the membrane filter element 20 is realized, and the improvement of the pure water discharge amount of the membrane filter element 20 is facilitated.
Referring to fig. 1, when the water purification system 100 washes the membrane filter element 20, the water pump 30 of the water purification system 100 is not started, so that the water pressure of the whole water purification system 100 is lower than the water pressure when the water purification system 100 prepares pure water, and the floating member 12 has a certain weight, and the wastewater discharged from the wastewater outlet of the membrane filter element 20 is low-pressure wastewater, so that the floating member 12 cannot move or block the second water outlet under the impact of the low-pressure wastewater, and most of the low-pressure wastewater entering the main pipeline 11 is discharged from the second water outlet, thereby ensuring the wastewater discharge speed of the membrane filter element 20, and facilitating the flushing of the membrane filter element 20.
The invention sets up the first water outlet and the second water outlet with upward opening at the water outlet 112 of the main pipe 11 of the waste water valve 10, and the aperture of the second water outlet is larger than that of the first water outlet; and a float 12 is movably installed in the main pipe 11. When the water inlet pressure of the water inlet port 111 reaches the preset water pressure, the floating piece 12 is propped against the water outlet port 112 by water and seals the second water outlet, so that the water in the main pipeline 11 can only be discharged from the first water outlet, and the waste water valve 10 plays a role in limiting flow; when the water inlet pressure of the water inlet port 111 is lower than the preset water pressure, the floating member 12 does not block the second water outlet, and at this time, the water in the main pipe 11 is basically discharged from the second water outlet, so that the water discharge speed of the waste water valve 10 is ensured, and the membrane filter element 20 is conveniently washed. Compared with the existing electromagnetic valve, the structure of the waste water valve 10 is simpler, and the waste water valve 10 of the invention utilizes the gravity of the floating piece 12 to adjust the opening of the waste water valve 10, namely the waste water valve 10 of the invention can automatically adjust the opening without a controller, and the operation is simpler.
In order to better seal the second water outlet, referring to fig. 1 or 2, in an embodiment of the present invention, the floating member 12 is spherically arranged. It should be noted that the spherical configuration of the floating member 12 does not represent that the floating member 12 is completely spherical, but only the surface of the floating member 12 is required to be substantially spherical, i.e. the surface of the floating member 12 facing the second water outlet is spherical. When the water inlet pressure of the water inlet 111 of the main pipe 11 reaches the preset water pressure, the surface of the floating member 12 facing the second water outlet is abutted against the second water outlet, and the spherical surface is in closer contact with the second water outlet, so that the floating member 12 can better seal the second water outlet.
It is obvious that the present design is not limited thereto, and the floating member 12 may have other shapes, for example, the floating member 12 may be provided in a tapered shape, a columnar shape or other shapes, so long as the floating member 12 is ensured to be capable of blocking the second water outlet without affecting the water passing through the first water outlet. When the floating piece 12 is conical, the surface of the floating piece 12 facing the second water outlet is conical; when the water inlet pressure of the water inlet 111 of the main pipe 11 reaches the preset water pressure, the smaller end of the floating member 12 is inserted into the second water outlet, and the floating member 12 is abutted to the second water outlet through the conical surface, so that the second water outlet can be plugged.
Further, a guiding structure is also provided in the main pipe 11. The guiding structure may be a guiding rod (not shown) extending from the water inlet port 111 to the water outlet port 112 of the main pipe 11, the floating member 12 is provided with a yielding hole matched with the guiding rod, and when the floating member 12 is installed in the main pipe 11, only one end of the guiding rod needs to pass through the yielding hole of the floating member 12. When the water inlet pressure of the water inlet port 111 of the main pipe 11 reaches the preset water pressure, the floating piece 12 is jacked up by the high-pressure water and moves towards the water outlet port 112 of the main pipe 11 along the guide rod so as to plug the second water outlet of the main pipe 11, thus ensuring that the floating piece 12 can plug the second water outlet, and avoiding the occurrence of the problem that the floating piece 12 cannot effectively seal the second water outlet due to the fact that the floating piece 12 is deviated along with the high-pressure water when moving from the water inlet port 111 to the water outlet port 112 of the main pipe 11.
The guiding structure may also be two sliding grooves (not shown) concavely arranged on the inner wall surface of the main pipe 11, and the two sliding grooves are oppositely arranged; accordingly, the two opposite sides of the floating member 12 respectively extend out of a sliding rod (not shown), and each sliding rod extends into a sliding slot. It will be appreciated that the cooperation of the sliding rod and the sliding groove is similar to the function of the guiding rod, so as to ensure the moving direction of the floating member 12, and avoid the problem that the floating member 12 cannot effectively seal the second water outlet due to the deviation of the position of the floating member 12 when the floating member 12 is jacked by water.
Obviously, the guiding structure is not limited to the guiding rod, the sliding groove and the sliding rod, but can be other structural members with guiding functions, and the guiding structure is listed here.
To ensure the current limiting capability of the waste valve 10, in one embodiment of the present invention, the float member 12 is made of steel and the float member 12 is spherically configured, i.e., the float member 12 is a steel ball. The steel ball may be a solid steel ball or a hollow steel ball, and the weight of the steel ball may be limited according to practical situations without specific limitation. Because the density of steel is great, the weight of the steel ball is greater than that of the spherical floating piece 12 made of other materials, so that the steel ball can be jacked up only by ensuring that the water inlet pressure of the water inlet port 111 of the main pipeline 11 enters the main pipeline 11 is greater, the second water outlet of the water outlet port 112 of the main pipeline 11 is not blocked when the water purification system 100 is flushed by the steel ball, and the flushing of the water purification system 100 is facilitated.
Further, the outer surface of the steel ball is coated with a layer of rubber. The rubber has good deformation capability, when the steel ball is jacked up by water and the second water outlet is plugged, the rubber layer coating the steel ball is deformed due to extrusion when contacting with the second water outlet, so that the rubber is matched with the second water outlet better, and the steel ball seals the second water outlet more tightly.
Further, a magnetic attraction piece is arranged at the second water outlet. When the steel ball is jacked up by the high-pressure water and moves to the water outlet 112, the magnetic attraction piece can adsorb the steel ball, so that the steel ball can be ensured to plug the second water outlet. The acting force between the magnetic attraction piece and the steel ball is smaller than the gravity of the steel ball, namely the acting force of the magnetic attraction piece on the steel ball only plays a guiding role.
In order to facilitate the production of the waste water valve 10, referring to fig. 1 or 2, in an embodiment of the invention, the water outlet 112 of the main pipe 11 is provided with a cover 13, and the cover 13 is provided with a first through hole 131 and a second through hole 132, wherein the aperture of the first through hole 131 is smaller than that of the second through hole 132, the first through hole 131 forms the first water outlet, and the second through hole 132 forms the second water outlet. The process of opening the holes in the cover plate 13 is relatively simple, so that the arrangement of the first water outlet and the second water outlet of the waste water valve 10 is facilitated, and the production and the manufacturing of the waste water valve 10 are facilitated.
It should be noted that, the cover plate 13 may be disposed at an end of the main pipe 11, or may be disposed in the main pipe 11 and adjacent to the water outlet 112 of the main pipe 11, and the specific position where the cover plate 13 is disposed is not specifically limited herein.
Further, the second through hole 132 is formed in the middle of the cover 13, and the first through hole 131 is formed in the side wall of the cover 13 adjacent to the main pipe 11. It should be noted that when the main pipe 11 is connected with water, the water flow speed in the area adjacent to the axis of the main pipe 11 is higher, the water flow speed in the position adjacent to the inner wall surface of the main pipe 11 is lower, and the second through hole 132 is arranged in the middle of the cover plate 13, that is, opposite to the axis of the main pipe 11, so that the water in the main pipe 11 is conveniently discharged from the second through hole 132; in addition, the end surface of the floating member 12 facing the water outlet 112 is smaller than the aperture of the main pipe 11, and when the floating member 12 is lifted up and seals the second through hole 132 by the high pressure water, the floating member 12 will not seal the first through hole 131, thus ensuring that the waste water valve 10 can perform the flow restriction function.
In order to avoid that the floating member 12 blocks the main pipe 11 and the main pipe 11 cannot normally pass water, referring to fig. 1 or 2, a water passing groove 113 is concavely formed on an inner wall surface of the main pipe 11, and the water passing groove 113 communicates the water inlet 111 of the main pipe 11 with the water outlet 112 of the main pipe 11. By this arrangement, the occurrence of a problem that the main pipe 11 is blocked by the float 12 is avoided.
The number of the water passing grooves 113 may be one or more, and the number of the water passing grooves 113 is not particularly limited and may be limited according to practical situations.
In order to facilitate assembly of the waste water valve 10, referring to fig. 1 or 2, the waste water valve 10 is further provided with a cover ring 14, and the cover ring 14 covers the water inlet 111 of the main pipe 11. This arrangement ensures that the float 12 mounted in the main conduit 11 does not fall out of the main conduit 11.
Specifically, the cover ring 14 includes a main body portion 141 provided in a ring shape, and a socket portion 142 extending from the main body portion 141 in the axial direction of the main body portion 141. When the cover ring 14 is assembled with the main pipe 11, the plugging portion 142 of the cover ring 14 is plugged into the main pipe 11 from the water inlet port 111 of the main pipe 11, and the main body portion 141 of the cover ring 14 abuts against the end of the water inlet port 111, so that the cover ring 14 and the main pipe 11 can be assembled conveniently.
Further, the plugging portion 142 is fixed to the main pipe 11 by screw connection, so that the assembly between the cover ring 14 and the main pipe 11 is more stable and firm. It is obvious that the cover ring 14 can also be connected to the main pipe 11 by welding, screwing, etc., which are not limited herein.
Obviously, in order to limit the floating member 12 in the main pipe 11, a plurality of limit protrusions adjacent to the water inlet port 111 may be provided on the inner wall surface of the main pipe 11, and the plurality of limit protrusions may be distributed along the circumferential direction of the main pipe 11. When the waste water valve 10 is in an idle state or the membrane filter 20 is in flushing, the floating member 12 stays on the plurality of protrusions under the action of gravity of the floating member, and the water entering the main pipeline 11 from the water inlet port 111 is smoothly discharged due to the arrangement of the plurality of protrusions at intervals.
In order to facilitate the arrangement of the pipeline, the waste water valve 10 is further provided with a transfer pipeline 15, wherein the transfer pipeline 15 is communicated with the water outlet port 112 of the main pipeline 11, and the axis of the water outlet pipeline is arranged at an included angle with the axis of the main pipeline 11. Preferably, the axis of the water outlet pipe is disposed at an angle of 90 ° to the axis of the main pipe 11, which facilitates the arrangement of the pipes of the water purification system 100.
The present invention also proposes a water purification system 100, where the water purification system 100 includes a membrane filter element 20 and a wastewater valve 10, and the specific structure of the wastewater valve 10 refers to the above embodiment, and since the water purification system 100 adopts all the technical solutions of all the embodiments, at least has all the beneficial effects brought by the technical solutions of the embodiments, and will not be described in detail herein.
Specifically, referring to fig. 3, the water purification system 100 includes a membrane cartridge 20, a waste water valve 10, a water pump 30, a first solenoid valve 40, a second solenoid valve 50, a controller (not shown), and other components.
The membrane filter core 20 is provided with a water inlet, a pure water port and a waste water port, wherein the water inlet is connected with the water pump 30 through a pipeline, and the waste water port is communicated with the water inlet 111 of the waste water valve 10 through a pipeline; one end of the first electromagnetic valve 40 is communicated with the water pump 30, and the other end of the first electromagnetic valve 40 is communicated with a water source; one end of the second electromagnetic valve 50 is communicated with the water pump 30, and the other end of the second electromagnetic valve 50 is communicated with a water source; that is, the first solenoid valve 40 and the second solenoid valve 50 are disposed in parallel in the water purification system 100; the controller is electrically connected to the water pump 30, the first electromagnetic valve 40 and the second electromagnetic valve 50 to control the water pump 30, the first electromagnetic valve 40 and the second electromagnetic valve 50 to work.
It should be noted that, the aperture of the second electromagnetic valve 50 is larger than the aperture of the first electromagnetic valve 40, that is, the water flow rate of the second electromagnetic valve 50 is larger than the water flow rate of the first electromagnetic valve 40.
When pure water is prepared by the water purification system 100, the controller controls the second electromagnetic valve 50 to be opened and simultaneously controls the water pump 30 to be started, external raw water flows into the membrane filter core 20 through the second electromagnetic valve 50 and the water pump 30, and as the water pressure of the external raw water is increased when the external raw water passes through the water pump 30, the raw water entering the membrane filter core 20 is high-pressure water, so that water discharged from a waste water port of the membrane filter core 20 after being filtered by the membrane filter core 20 is high-pressure waste water, and when the high-pressure waste water enters the waste water valve 10, the floating piece 12 of the waste water valve 10 moves to the water outlet port 112 of the main pipeline 11 under the impact of the high-pressure waste water; because the aperture of the second water outlet is larger than that of the first water outlet, when the main pipeline 11 is filled with water, the water flows out from the second water outlet with larger aperture preferentially, so that the floating piece 12 can move to the second water outlet and plug the second water outlet under the impact of the water, the water in the main pipeline 11 can only be discharged from the first water outlet with smaller aperture, the flow restriction of the waste water gap of the membrane filter element 20 is realized, and the improvement of the pure water discharge amount of the membrane filter element 20 is facilitated.
When the water purification system 100 washes the membrane filter element 20, the controller only controls the first electromagnetic valve 40 to be opened, the water pump 30 is not started at the moment, and the aperture of the first electromagnetic valve 40 is smaller than that of the second electromagnetic valve 50, so that when the water purification system 100 washes the membrane filter element 20, the water pressure and the water quantity are lower than those when the water purification system 100 prepares pure water; because the floating member 12 has a certain weight, and the wastewater discharged from the wastewater port of the membrane filter core 20 is low-pressure wastewater, the floating member 12 cannot move or block the second water outlet under the impact of the low-pressure wastewater, and most of the low-pressure wastewater entering the main pipeline 11 is discharged from the second water outlet, so that the wastewater discharge speed of the membrane filter core 20 is ensured, and the membrane filter core 20 is conveniently washed.
Further, the water purification system 100 further includes a pre-filter 60, the pre-filter 60 may be a PP cotton filter, an activated carbon filter, etc., and water inlets of the pre-filter 60 are respectively communicated with the first electromagnetic valve 40 and the second electromagnetic valve 50, and a water outlet of the pre-filter 60 is connected with the water pump 30. The arrangement of the pre-filter element 60 can effectively block large-particle pollutants in raw water, so that the amount of large-particle matters entering the membrane filter element 20 is reduced, and the reverse osmosis membrane in the membrane filter element 20 is well protected.
Further, the water purification system 100 further includes a post-filter element 70, wherein a water inlet of the post-filter element 70 is communicated with the pure water port of the membrane filter element 20, and a water outlet of the post-filter element 70 is communicated with an external pipeline. The post filter element 70 is a granular activated carbon filter element, and is mainly used for improving the taste of pure water so as to improve the experience of users.
