Description

Technical Field

[0001] The utility model relates to a soft water valve, and more particularly to an energy-saving multi-functional soft water valve. Background Art

[0002] Multi-functional control valves are often used in current industrial or domestic water treatment systems. Especially in the field of soft water treatment, multi-functional soft water valves have been widely used to switch water flow channels to achieve functions such as running water production, backwashing, salt absorption / slow washing, water replenishment to the salt tank, and normal washing. The multi-functional soft water valve with plane seal first created by Wenzhou Runxin Machinery Manufacturing Co., Ltd. has become the mainstream of soft water treatment control valves in the market due to its simple structure, high reliability and other characteristics. In the prior art, the multi-functional soft water valve with plane seal usually replenishes raw water (i.e., hard water) to the salt tank, and the water replenishment is an independent time-consuming state. In addition, for the soft water valve with both forward flow regeneration and reverse flow regeneration functions, the soft water output flow is limited due to the limitation of the principle design.

[0003] Facing different market and application requirements, such as the North American household market, the function of discharging raw water during the regeneration process is required to solve the problem of no water available in the water treatment system during the regeneration process; another example is the requirement for the soft water valve closing function to meet the need that when the water softener stops using water for a long time, first absorb salt and soak the resin, and then close all channels through the soft water valve to protect the resin and prevent the growth of bacteria.

[0004] In response to the above problems, the company designed an energy-saving multi-functional soft water valve on July 31, 2014. The soft water valve realizes various functions of the soft water valve through the cooperation of the first through hole to the seventh through hole on the fixed valve plate and the water inlet channel, the conduction channel and the sewage discharge channel on the moving valve plate. However, there are still multiple blank spaces on the fixed valve plate with the above structure, and the arrangement of the holes is not reasonable enough, resulting in a certain shortage in the flow rate of the soft water valve.

According to the drawings, a total of five embodiments are provided in this embodiment. Among them, the fixed valve plate 10 and the moving valve plate 20 in Embodiment I can achieve 9 equal divisions. The fixed valve plate 10 and the moving valve plate 20 in Embodiment II are the mirror structures of Embodiment I. The fixed valve plate 10 and the moving valve plate 20 in Embodiment III lack the setting of the blind hole 100 compared with Embodiment I. The first to eighth through holes on the fixed valve plate 10 and the moving valve plate 20 in Embodiment IV are all different from those in Embodiment I. The first to ninth through holes on the fixed valve plate 10 and the moving valve plate 20 in Embodiment V are all different from those in Embodiment I, and the eighth through hole is not provided. Among them Figures 1 to 40 the word "inner" on the fixed valve plate 10 indicates being connected to the lower water distribution interface 39, the word "outer" indicates being connected to the upper water distribution interface 38, the word "inject" indicates being connected to the injector water inlet 34, the word "suction" indicates being connected to the injector water outlet 35, the word "out" indicates being connected to the water outlet 32, and the word "dirt" indicates being connected to the sewage outlet 33.

[0041] Embodiment 1: When using this embodiment, install the soft water valve onto the resin tank 40. The filter media or resin 44 is filled in the resin tank 40. The upper water distributor 41 is connected to the upper water distribution interface 38 of the valve body 30. The upper water distribution interface 38 communicates with the upper part of the resin tank 40 through the upper water distributor 41. The lower water distributor 43 is connected to the lower water distribution interface 39 of the valve body 30 through the central pipe 42. The lower water distribution interface communicates with the lower part of the resin tank 40 through the central pipe 42 and the lower water distributor 43. Connect the water inlet 31 to the water source, connect the drain port 33 to the drainage location, and connect the brine suction port 36 to the brine valve 52 in the brine tank 51 through the connecting pipe 50. If the present utility model is used as a filtration valve, only need to block the brine suction port 36. Rotate the valve stem 61 and the moving valve plate 20 through the driving device 62. The rotation of the moving valve plate 20 forms different cooperation states with the fixed valve plate 10 to achieve different functions of the present utility model. The driving device 62 can be any rotating mechanism such as electric, pneumatic or manual. The following takes the softening water process as an example to specifically illustrate the present utility model. The drain port 33 in this embodiment can be opened on the valve stem or on the valve body, depending on the user's usage situation.

[0042] Embodiment 1: During the regeneration process, the original water comes out from the water outlet. The technical solution of discharging sewage through the ninth through hole of the fixed valve plate communicating with the drain port of the valve body is adopted.

[0043] As Figure 4 shown, in Embodiment 1, use Figure 2 and Figure 3The shown combination of moving and fixed valve plates. A multifunctional soft water valve includes a valve body 30, a jet injector 37, a fixed valve plate 10, a moving valve plate 20, a gland 60, a valve stem 61, and a driving device 62 for driving the valve stem 61 and the moving valve plate 20. The fixed valve plate 10 is fixedly installed on the valve body 30. The moving valve plate 20 is connected to the valve stem 61. The valve body 30 is provided with a water inlet 31, a water outlet 32, a sewage outlet 33, an upper water distribution interface 38, and a lower water distribution interface 39. A jet injector water inlet 34 and a jet injector water outlet 35 are also provided inside the valve body 30. The jet injector 37 is connected to the valve body 30 through the jet injector water inlet 34 and the jet injector water outlet 35. A brine suction port 36 is provided on the jet injector 37. Nine through holes are provided on the fixed valve plate 10: a first through hole 1, a second through hole 2, a third through hole 3, a fourth through hole 4, a fifth through hole 5, a sixth through hole 6, a seventh through hole 7, an eighth through hole 8, and a ninth through hole 9. The first through hole 1, the second through hole 2, and the seventh through hole 7 communicate with each other and are connected to the lower water distribution interface 39. The third through hole 3 and the fifth through hole 5 communicate with each other and are connected to the upper water distribution interface 38. The fourth through hole 4 is connected to the jet injector water inlet 34. The sixth through hole 6 is connected to the jet injector water outlet 35. The eighth through hole 8 is connected to the water outlet 32. A semi-blind hole 100 is provided on the outer circumference of the eighth through hole 8 and is connected to the eighth through hole 8. The first through hole 1, the second through hole 2, the third through hole 3, the fourth through hole 4, the fifth through hole 5, the sixth through hole 6, the seventh through hole 7, and the eighth through hole 8 are arranged in sequence on the circumference of the fixed valve plate 10. The fourth through hole 4 is close to the outer circumference. The ninth through hole 9 is at the center of the fixed valve plate 10. The moving valve plate 20 is provided with a water inlet channel 21, a conduction channel 22, and a sewage channel 23. The water inlet channel 21 is connected to the water inlet 31. The sewage channel 23 is a blind hole.

[0044] Such a valve plate structure design has the following advantages: The fixed valve plate 10 with an additional "inner" through hole (such as the second through hole 2) and an "outer" through hole (such as the fifth through hole 5). Compared with the structure of the fixed valve plate 10 in the prior art, the planar sealing soft water valve with both forward flow regeneration and reverse flow regeneration functions is more advanced in principle design than the limitation in the prior art that causes limited softened water output flow. It makes the through hole arrangement on the fixed valve plate 10 more reasonable, and can produce a larger flow of soft water under the same conditions. In addition, the sewage channel 23 includes a central part 231 and a fan-shaped part 232. The central part 231 is coaxially arranged with the center of the moving valve plate 20. The central angle of the fan-shaped part 232 is connected to the side of the central part 231 so that the fan-shaped part 232 communicates with the central part 231. An expansion part 233 extending towards the circumference of the moving valve plate 20 extends from the side of the fan-shaped part 232 away from the central part 231. By using the function of the expansion part 233, it can prevent the ninth through hole 9 from communicating with the fourth through hole 4 during operation and can also increase the flow rate of the sewage channel 23, such as Figure 5As shown, a fan-shaped ring-shaped conduction channel 22 is also adopted. An additional part 221 extending towards the circumference of the moving valve plate 20 is provided on one side of the conduction channel 22 away from the center of the moving valve plate 20. Through the setting of the additional part 221, during the normal flushing process, on the one hand, the communication between the fifth through hole 5 and the fourth through hole 4 can be avoided, and on the other hand, the flow cross-section of the conduction channel can be further expanded. As Figure 17 shown, the flow rate of softened water that can flow through is further increased.

[0045] The following details seven functions generated by different matching methods of the moving and fixed valve plates.

[0046] Operating the softening function: As Figure 4 、 5 shown, by rotating the valve stem 61, the water inlet channel 21 of the moving valve plate 20 is communicated with the fifth through hole 5 of the fixed valve plate 10. The conduction channel 22 of the moving valve plate 20 is communicated with the seventh through hole 7, the eighth through hole 8 of the fixed valve plate 10 and the semi-blind hole 100 on the outer side of its circumference. The sewage discharge channel 23 of the moving valve plate 20 is communicated with the ninth through hole 9 of the fixed valve plate 10. In this matching state of the moving and fixed plates, raw water enters the valve body 30 from the water inlet 31, enters the fifth through hole 5 of the fixed valve plate 10 through the water inlet channel 21 on the moving valve plate 20. Since the fifth through hole 5 is communicated with the upper water distribution interface 38, the water flow passes through the upper water distribution interface 38, enters the upper part of the resin tank 40 through the upper water distributor 41. The water flow passes through the resin 44 and is softened and then flows into the lower water distributor 43, and then flows to the lower water distribution interface 39 through the central pipe 42. Since the lower water distribution interface 39 is communicated with the seventh through hole 7, the softened water flows to the seventh through hole 7, is guided to the eighth through hole 8 through the conduction channel 22 of the moving valve plate 20. Since the eighth through hole 8 is communicated with the water outlet 32, finally the softened water flows out from the water outlet 32. Although the sewage discharge channel 23 of the moving valve plate 20 is communicated with the ninth through hole 9 of the fixed valve plate 10, there is no water flow.

[0047] Operating the softening + salt tank water replenishing function: As Figure 6 、 7As shown in the figure, by rotating the valve stem 61, the water inlet passage 21 of the movable valve plate 20 is communicated with the fifth through hole 5 of the fixed valve plate 10. The conduction passage 22 of the movable valve plate 20 is communicated with the sixth through hole 6, the seventh through hole 7, the eighth through hole 8 of the fixed valve plate 10 and the semi-blind hole 100 on the outer circumference thereof. The sewage discharge passage 23 of the movable valve plate 20 is communicated with the ninth through hole 9 of the fixed valve plate 10. In this matching state of the movable and fixed valve plates, raw water enters the valve body 30 from the water inlet 31, enters the fifth through hole 5 of the fixed valve plate 10 through the water inlet passage 21 on the movable valve plate 20. Since the fifth through hole 5 is communicated with the upper water distribution interface 38, the water flow passes through the upper water distribution interface 38 and enters the upper part of the resin tank 40 through the upper water distributor 41. The water flow passes through the resin 44 and is softened and then flows into the lower water distributor 43, and then flows to the lower water distribution interface 39 through the central pipe 42. Since the lower water distribution interface 39 is communicated with the seventh through hole 7, the softened water flows to the seventh through hole 7, and is guided to the sixth through hole 6, the eighth through hole 8 and the semi-blind hole 100 on the outer circumference thereof through the conduction passage 22 of the movable valve plate 20. Since the eighth through hole 8 and the semi-blind hole 100 on the outer circumference thereof are communicated with the water outlet 32, most of the softened water flows out from the water outlet 32. And since the sixth through hole 6 is communicated with the water outlet 35 of the ejector, a small part of the softened water flows to the water outlet 35 of the ejector, and flows to the salt valve 52 through the salt suction port 36 and the connecting pipe 50 to supplement soft water to the salt tank. Although the sewage discharge passage 23 of the movable valve plate 20 is communicated with the ninth through hole 9 of the fixed valve plate 10, there is no water flow.

[0048] Closing function: As Figure 8 , 9 shown in the figure, by rotating the valve stem 61, the water inlet passage 21 of the movable valve plate 20 has no communication relationship with the fixed valve plate 10. The conduction passage 22 of the movable valve plate 20 is communicated with the fifth through hole 5 of the fixed valve plate 10. The sewage discharge passage 23 of the movable valve plate 20 is communicated with the ninth through hole 9 of the fixed valve plate 10. In this matching state of the movable and fixed valve plates, there is no water flow.

[0049] Backwashing + raw water flowing out from the water outlet function: As Figure 10 , 11As shown, by rotating the valve stem 61, the water inlet channel 21 of the movable valve plate 20 is communicated with the seventh through hole 7 of the fixed valve plate 10. The eighth through hole 8 and the semi-blind hole 100 on the outer circumference thereof are directly communicated with the water inlet 31. The conduction channel 22 of the movable valve plate 20 is communicated with the first through hole 1 and the second through hole 2 of the fixed valve plate 10. The sewage discharge channel 23 of the movable valve plate 20 is communicated with the fifth through hole 5 and the ninth through hole 9 of the fixed valve plate 10. In this state of cooperation between the movable and fixed valve plates, raw water enters the valve body 30 from the water inlet 31. A part of the water flow enters the seventh through hole 7 of the fixed valve plate 10 through the water inlet channel 21 on the movable valve plate 20. Since the seventh through hole 7 is communicated with the lower water distribution interface 39, the water flow flows to the lower water distribution interface 39 and then flows out through the central pipe 42 and the lower water distributor 43. The water flow loosens and flushes the resin 44 from the bottom of the resin tank 40 and reaches the upper part of the resin tank 40 and then flows to the upper water distribution interface 38 through the upper water distributor 41. Since the upper water distribution interface 38 is communicated with the fifth through hole 5 of the fixed valve plate 10, the water flow flows to the fifth through hole 5 and is guided to the ninth through hole 9 through the sewage discharge channel 23. Since the ninth through hole 9 is communicated with the sewage outlet 33, finally the water flow flows out from the sewage outlet 33. Another part of the water flow directly enters the semi-blind hole 100 on the outer circumference of the eighth through hole 8 of the fixed valve plate 10. Since the semi-blind hole 100 is communicated with the eighth through hole 8, and the eighth through hole 8 is communicated with the water outlet 32, the water flow flows out from the water outlet 32 after passing through the eighth through hole 8. Although the conduction channel 22 is communicated with the first through hole 1 and the second through hole 2, there is no water flow.

[0050] Brine suction countercurrent regeneration + raw water outlet function: As Figure 12 , 13As shown, by rotating the valve stem 61, the water inlet passage 21 of the movable valve plate 20 is communicated with the fourth through hole 4 of the fixed valve plate 10. The conduction passage 22 of the movable valve plate 20 is simultaneously communicated with the sixth through hole 6 and the seventh through hole 7 of the fixed valve plate 10. The eighth through hole 8 and the semi-blind hole 100 on the outer circumference thereof are directly communicated with the water inlet 31. The sewage discharge passage 23 of the movable valve plate 20 is simultaneously communicated with the third through hole 3 and the ninth through hole 9 of the fixed valve plate 10. In this cooperative state of the movable and fixed valve plates, raw water enters the valve body 30 from the water inlet 31. A part of the water flows through the water inlet passage 21 on the movable valve plate 20 and enters the fourth through hole 4 of the fixed valve plate 10. Since the fourth through hole 4 is communicated with the water inlet 34 of the injector, and the injector 37 is communicated with the valve body 30 through the water inlet 34 and the water outlet 35 of the injector, the water flows through the injector 37 and jets to generate negative pressure at the brine suction port 36, sucking the brine in the salt tank 51 through the salt valve 52 and the connecting pipe 50 into the water outlet 35 of the injector to be mixed with the raw water. Since the sixth through hole 6 is communicated with the water outlet 35 of the injector, the mixed brine flows into the sixth through hole 6, and then is guided to the seventh through hole 7 through the guiding passage 22 of the movable valve plate 20, flows through the lower water distribution interface 39, the central pipe 42, and the lower water distributor 43 in sequence to enter the lower part of the resin tank 40, flows reversely through the resin 44 for its regeneration, then flows to the upper part of the resin tank 40 and enters the upper water distribution interface 38 from the upper water distributor 41. Since the third through hole 3 is communicated with the upper water distribution interface 38 and the ninth through hole 9 is communicated with the sewage outlet 33, the water flows into the third through hole 3, is guided to the ninth through hole 9 through the sewage discharge passage 23, and finally discharges from the sewage outlet 33. Another part of the water directly enters the semi-blind hole 100 on the outer circumference of the eighth through hole 8 of the fixed valve plate 10. Since the semi-blind hole 100 is communicated with the eighth through hole 8, and the eighth through hole 8 is communicated with the water outlet 32, the water flows out from the water outlet 32 after flowing through the eighth through hole 8.

[0051] Brine suction and forward flow regeneration + raw water outlet function: As Figure 14 , 15As shown in the figure, by rotating the valve stem 61, the water inlet passage 21 of the movable valve plate 20 is communicated with the fourth through hole 4 of the fixed valve plate 10. The conduction passage 22 of the movable valve plate 20 is simultaneously communicated with the fifth through hole 5 and the sixth through hole 6 of the fixed valve plate 10. The sewage discharge passage 23 of the movable valve plate 20 is simultaneously communicated with the second through hole 2 and the ninth through hole 9 of the fixed valve plate 10. The eighth through hole 8 and the semi-blind hole 100 on the outer circumference thereof are directly communicated with the water inlet 31. In this state of cooperation between the movable and fixed valve plates, raw water enters the valve body 30 from the water inlet 31. A part of the water flows through the water inlet passage 21 on the movable valve plate 20 and enters the fourth through hole 4 of the fixed valve plate 10. Since the fourth through hole 4 is communicated with the water inlet 34 of the ejector, and the ejector 37 is communicated with the valve body 30 through the water inlet 34 and the water outlet 35 of the ejector, the water flows through the ejector 37 and jets to generate negative pressure at the brine suction port 36, sucking the brine in the salt tank 51 through the salt valve 52 and the connecting pipe 50 into the water outlet 35 of the ejector and mixing it with the raw water. Since the sixth through hole 6 is communicated with the water outlet 35 of the ejector, the mixed brine flows into the sixth through hole 6, and then is guided to the fifth through hole 5 through the guiding passage 22 of the movable valve plate 20, sequentially flows through the upper water distribution interface 38 and the upper water distributor 41 and enters the upper part of the resin tank 40, flows through the resin 44 in the forward direction for regeneration, then flows to the lower part of the resin tank 40 and enters through the lower water distributor 43 and flows to the lower water distribution interface 39 through the central pipe 42. Since the second through hole 2 is communicated with the lower water distribution interface 39 and the ninth through hole 9 is communicated with the sewage discharge port 33, the water flows into the second through hole 2, is guided to the ninth through hole 9 through the sewage discharge passage 23, and finally discharges from the sewage discharge port 33. Another part of the water directly enters the semi-blind hole 100 on the outer circumference of the eighth through hole 8 of the fixed valve plate 10. Since the semi-blind hole 100 is communicated with the eighth through hole 8, and the eighth through hole 8 is communicated with the water outlet 32, the water flows out from the water outlet 32 after flowing through the eighth through hole 8.

[0052] Normal flushing + raw water discharging function at the water outlet: As Figure 16 , 17As shown in the figure, by rotating the valve stem 61, the water inlet channel 21 of the movable valve plate 20 is communicated with the third through hole 3 of the fixed valve plate 10, the conduction channel 22 of the movable valve plate 20 is simultaneously communicated with the fifth through hole 5 of the fixed valve plate 10, the sewage discharge channel of the movable valve plate 20 is simultaneously communicated with the first through hole 1 and the ninth through hole 9 of the fixed valve plate 10, and the eighth through hole 8 and the semi-blind hole 100 on the outer circumference thereof are directly communicated with the water inlet 31. In this state of cooperation between the movable and fixed valve plates, raw water enters the valve body 30 from the water inlet 31. A part of the water flows through the water inlet channel 21 on the movable valve plate 20 and enters the third through hole 3 of the fixed valve plate 10. Since the third through hole 3 is communicated with the upper water distribution interface 38, the water flows through the upper water distribution interface 38 and the upper water distributor 41 in sequence and enters the upper part of the resin tank 40. The water flows through the resin 44 and reaches the lower part of the resin tank, and then flows through the lower water distributor 43 and the central pipe 42 in sequence and enters the lower water distribution interface 39. Since the first through hole 1 is communicated with the lower water distribution interface 39 and the ninth through hole 9 is communicated with the sewage discharge port 33, the water flows into the first through hole 1, is guided to the ninth through hole 9 through the sewage discharge channel 23, and finally discharges from the sewage discharge port 33. Another part of the water directly enters the semi-blind hole 100 on the outer circumference of the eighth through hole 8 of the fixed valve plate 10. Since the semi-blind hole 100 is communicated with the eighth through hole 8, and the eighth through hole 8 is communicated with the water outlet 32, the water flows out from the water outlet 32 after flowing through the eighth through hole 8. Although the conduction channel 22 is communicated with the fifth through hole 5, there is no water flow.

[0053] Embodiment 2: The structures of the movable and fixed valve plates in Embodiment 1 are mirrored to obtain the structures of the movable and fixed valve plates in Embodiment 2, which have a technical solution equivalent to all the functions of Embodiment 1.

[0054] As Figure 4 , 18 , as shown in FIGS. 19, in Embodiment 2, use Figure 18 , 19The shown combination of movable and fixed valve plates. A multifunctional soft water valve includes a valve body 30, a jet ejector 37, a fixed valve plate 10, a movable valve plate 20, a gland 60, a valve stem 61, and a driving device 62 for driving the valve stem 61 and the movable valve plate 20. The fixed valve plate 10 is fixedly installed on the valve body 30. The movable valve plate 20 is connected to the valve stem 61. The valve body 30 is provided with a water inlet 31, a water outlet 32, a sewage outlet 33, an upper water distribution interface 38, and a lower water distribution interface 39. A jet ejector water inlet 34 and a jet ejector water outlet 35 are further provided inside the valve body 30. The jet ejector 37 is connected to the valve body 30 through the jet ejector water inlet 34 and the jet ejector water outlet 35. A salt suction port 36 is provided on the jet ejector 37. Nine through holes are provided on the fixed valve plate 10: a first through hole 1, a second through hole 2, a third through hole 3, a fourth through hole 4, a fifth through hole 5, a sixth through hole 6, a seventh through hole 7, an eighth through hole 8, and a ninth through hole 9. The first through hole 1, the second through hole 2, and the seventh through hole 7 communicate with each other and are connected to the lower water distribution interface 39. The third through hole and the fifth through hole communicate with each other and are connected to the upper water distribution interface 38. The fourth through hole 4 is connected to the jet ejector water inlet 34. The sixth through hole 6 is connected to the jet ejector water outlet 35. The eighth through hole 8 is connected to the water outlet 32. A semi-blind hole 100 is provided on the outer circumference of the eighth through hole and is connected to the eighth through hole 8. The first through hole 1, the second through hole 2, the third through hole 3, the fourth through hole 4, the fifth through hole 5, the sixth through hole 6, the seventh through hole 7, and the eighth through hole 8 are arranged in sequence on the circumference of the fixed valve plate 10. The fourth through hole is close to the outer circumference of the circle. The ninth through hole 9 is at the center of the fixed valve plate 10. The movable valve plate 20 is provided with a water inlet channel 21, a conduction channel 22, and a sewage channel 23. The water inlet channel 21 is connected to the water inlet 31. The sewage channel 23 is a blind hole.

[0055] The structural relationship between Embodiment 2 and Embodiment 1 lies in that: the structure of the movable valve plate 20 in Embodiment 2 and the structure of the movable valve plate 20 in Embodiment 1 are in a mirror image relationship; the structure of the fixed valve plate 10 in Embodiment 2 and the structure of the fixed valve plate 10 in Embodiment 1 are in a mirror image relationship. Therefore, the functions of Embodiment 2 and Embodiment 1 are the same.

[0056] The difference between Embodiment 2 and Embodiment 1 is that: the rotation direction during function switching in Embodiment 2 is exactly opposite to the rotation direction of function switching in Embodiment 1, but it does not affect the sequential switching of each function. Therefore, the realization of each function in Embodiment 2 is the same as the realization of each function in Embodiment 1. The seven functions of Embodiment 2 will not be elaborated one by one here.

[0057] Embodiment 3: During the regeneration process, no raw water comes out of the water outlet. The technical solution of discharging sewage through the seventh through hole 7 of the fixed valve plate 10 connected to the sewage outlet of the valve body is adopted.

[0058] As Figure 2 、 4 、shown in 20, in Embodiment 3, use Figure 2 andFigure 20 The shown movable and fixed valve plates combination. A multifunctional water softening valve, comprising a valve body 30, a jet ejector 37, a fixed valve plate 10, a movable valve plate 20, a gland 60, a valve stem 61 and a driving device 62 for driving the valve stem 61 and the movable valve plate 20. The fixed valve plate 10 is fixedly installed on the valve body 30. The movable valve plate 20 is connected to the valve stem 61. The valve body 30 is provided with a water inlet 31, a water outlet 32, a sewage outlet 33, an upper water distribution interface 38 and a lower water distribution interface 39. An inlet of the jet ejector 34 and an outlet of the jet ejector 35 are further arranged in the valve body 30. The jet ejector 37 is communicated with the valve body 30 through the inlet of the jet ejector 34 and the outlet of the jet ejector 35. A salt suction port 36 is arranged on the jet ejector 37. Nine through holes are arranged on the fixed valve plate 10: a first through hole 1, a second through hole 2, a third through hole 3, a fourth through hole 4, a fifth through hole 5, a sixth through hole 6, a seventh through hole 7, an eighth through hole 8 and a ninth through hole 9. The first through hole 1, the second through hole 2 and the seventh through hole 7 are communicated with each other and are communicated with the lower water distribution interface 39. The third through hole and the fifth through hole are communicated with each other and are communicated with the upper water distribution interface 38. The fourth through hole 4 is communicated with the inlet of the jet ejector 34. The sixth through hole 6 is communicated with the outlet of the jet ejector 35. The eighth through hole 8 is communicated with the water outlet 32. A semi-blind hole 100 is arranged on the outer circumference of the eighth through hole and is communicated with the eighth through hole 8. The first through hole 1, the second through hole 2, the third through hole 3, the fourth through hole 4, the fifth through hole 5, the sixth through hole 6, the seventh through hole 7 and the eighth through hole 8 are arranged in sequence on the circumference of the fixed valve plate 10. The fourth through hole is close to the outer circumference of the circle. The ninth through hole 9 is at the center of the fixed valve plate 10. The movable valve plate 20 is provided with a water inlet channel 21, a conduction channel 22 and a sewage channel 23. The water inlet channel 21 is communicated with the water inlet 31. The sewage channel 23 is a blind hole.

[0059] By adopting different matching modes of such movable and fixed valve plates, seven functions can be generated: operation softening function, operation softening + salt tank water replenishing function, closing function, backwashing function, salt suction countercurrent regeneration, salt suction forward flow regeneration function, and normal flushing function.

[0060] The structural difference between Embodiment 3 and Embodiment 1 is as follows: there is no semi-blind hole 100 on the outer circumference of the eighth through hole 8 of the fixed valve plate 10 in Embodiment 3, while there is a semi-blind hole 100 on the outer circumference of the eighth through hole 8 of the fixed valve plate 10 in Embodiment 1. At the same time, there are no expansion parts 233 and additional parts 221 on the moving valve plate 20. This structural difference results in differences only during the regeneration process as follows: in Embodiment 1, during the regeneration processes of backwashing, salt absorption with countercurrent regeneration or salt absorption with co-current regeneration, and normal flushing, since the eighth through hole 8 of the fixed valve plate 10 is connected to the water outlet 32 and the semi-blind hole 100 on the outer circumference of the eighth through hole 8 is always connected to the water inlet 31, there is always raw water flowing out of the water outlet 32 during the regeneration process; in Embodiment 3, since there is no semi-blind hole 100 on the outer circumference of the eighth through hole 8 of the fixed valve plate 10, during the regeneration processes of backwashing, salt absorption with co-current regeneration, salt absorption with countercurrent regeneration, and normal flushing, the eighth through hole 8 and the moving valve plate 20 are in a closed state without water flow, so there is no water flowing out of the water outlet 32 during the regeneration process. Therefore, only one example is given here to elaborate on the backwashing function in detail, and the other five functions will not be described further.

[0061] Backwashing function: As Figure 21 , 22 shown, by rotating the valve stem 61, the water inlet channel 21 of the moving valve plate 20 is connected to the seventh through hole 7 of the fixed valve plate 10, the conducting channel 22 of the moving valve plate 20 is connected to the first through hole 1 and the second through hole 2 of the fixed valve plate 10, and the sewage discharge channel 23 of the moving valve plate 20 is connected to the fifth through hole 5 and the ninth through hole 9 of the fixed valve plate 10. In this state of cooperation between the moving and fixed valve plates, raw water enters the valve body 30 from the water inlet 31, flows through the water inlet channel 21 on the moving valve plate 20 and enters the seventh through hole 7 of the fixed valve plate 10. Since the seventh through hole 7 is connected to the lower water distribution interface 39, the water flow reaches the lower water distribution interface 39 and then flows out through the central pipe 42 and the lower water distributor 43. The water flow loosens and flushes the resin 44 in the reverse direction from the bottom of the resin tank 40 and reaches the upper part of the resin tank 40, then flows to the upper water distribution interface 38 through the upper water distributor 41. Since the upper water distribution interface 38 is connected to the fifth through hole 5 of the fixed valve plate 10, the water flow reaches the fifth through hole 5 and is guided to the ninth through hole 9 through the sewage discharge channel 23. Since the ninth through hole 9 is connected to the sewage outlet 33, finally the water flow flows out from the sewage outlet 33. Although the conducting channel 22 is connected to the first through hole 1 and the second through hole 2, there is no water flow.

[0062] Embodiment 4: The structural difference between Embodiment 4 and Embodiments 1 to 3 lies in that the shapes of the first through hole 1 to the ninth through hole 9 on the fixed valve plate 10 are different, and the external components they are connected to are also different. At the same time, the shapes and positions of the conducting channel 22, the sewage discharge channel 23, and the water inlet channel 21 on the moving valve plate 20 are also different. Refer to Figure 23As shown, the sewage discharge channel 23 includes a central part 231 and a sector part 232. The sector part 232, the water inlet channel 21, and the conduction channel 22 are circumferentially distributed on the moving valve plate 20 with the central part 231 as the center. The conduction channel 22 is located between the water inlet channel 21 and the sector part 232. The central part 231 is coaxially arranged with the center of the moving valve plate 20. The central angle of the sector part 232 is connected to the side of the central part 231 so that the sector part 232 and the central part 231 communicate with each other. The sector part 232, the conduction channel 22, and the water inlet channel 21 of the sewage discharge channel 23 are located at the lower right corner of the disc-shaped moving valve plate 20. Refer to Figure 24 As shown, the first through hole 1, the fourth through hole 4, and the fifth through hole 5 communicate with each other and are connected to the upper water distribution interface 38. The third through hole 3 and the sixth through hole 6 communicate with each other and are connected to the lower water distribution interface 39. The second through hole 2 is connected to the outlet of the injector 35. The eighth through hole 8 is connected to the inlet of the injector 34. In the fourth embodiment, the apertures of the first through hole 1 and the eighth through hole 8 are smaller than those in the first to third embodiments, and the shape is square, and they are arranged close to the circumference of the moving valve plate 20. The remaining second through hole 2 to the seventh through hole 7 are all fan-shaped, and the overall size and shape are slightly different from those in the first to third embodiments. Through the structures of the fixed valve plate 10 and the moving valve plate 20 described above, the cooperation mode of the moving valve plate 20 and the fixed valve plate 10 when realizing the above seven functions is as Figure 25 It is a schematic diagram of the cooperation between the moving valve plate 20 and the fixed valve plate 10 when running the softening function. Figure 26 It is a schematic diagram of the cooperation between the moving valve plate 20 and the fixed valve plate 10 when running the softening + salt tank water replenishing function. Figure 27 It is a schematic diagram of the cooperation between the moving valve plate 20 and the fixed valve plate 10 when sucking salt and flowing in the forward direction for regeneration + discharging raw water from the outlet. Figure 28 It is a schematic diagram of the cooperation between the moving valve plate 20 and the fixed valve plate 10 when sucking salt and flowing in the reverse direction for regeneration. Figure 29 It is a schematic diagram of the cooperation between the moving valve plate 20 and the fixed valve plate 10 when in the closed state. Figure 30 It is a schematic diagram of the cooperation between the moving valve plate 20 and the fixed valve plate 10 when in the backwashing function. Figure 31 It is a schematic diagram of the cooperation between the moving valve plate 20 and the fixed valve plate 10 when in the normal flushing function.

[0063] Embodiment Five: The structural difference between Embodiment Five and Embodiments One to Three lies in that the shapes of the first through hole 1 to the ninth through hole 9 on the fixed valve plate 10 are different, and the external components they are connected to are also different. At the same time, the shapes and positions of the conduction channel 22, the sewage discharge channel 23, and the water inlet channel 21 on the moving valve plate 20 are also different. Refer to Figure 32As shown, the conduction channel 22, the sewage discharge channel 23, and the water inlet channel 21 are evenly distributed on the moving valve plate 20, and the included angles between adjacent ones are approximately the same. The sewage discharge channel 23 includes a central part 231 and a fan-shaped part 232. The fan-shaped part 232, the water inlet channel 21, and the conduction channel 22 are circumferentially distributed on the moving valve plate 20 with the central part 231 as the center. The water inlet channel 21 is between the conduction channel 22 and the fan-shaped part 232. The central part 231 is coaxially arranged with the center of the moving valve plate 20. The central angle of the fan-shaped part 232 is connected to the side of the central part 231 so that the fan-shaped part 232 communicates with the central part 231. Refer to Figure 33 As shown, the first through hole 1 and the sixth through hole 6 communicate with each other and are connected to the lower water distribution interface 39; the second through hole 2 and the fourth through hole 4 communicate with each other and are connected to the upper water distribution interface 38. The third through hole 3 is connected to the water inlet of the ejector 34; the fifth through hole 5 is connected to the water outlet of the ejector 35; the seventh through hole 7 is connected to the water outlet 32. From the above settings, it can be seen that compared with the fixed valve plate 10 structure of Embodiments 1 to 3, in Embodiment 5, the setting of the second through hole 2 is cancelled, and then the second through hole 2 is successively used to replace the third through hole 3 of Embodiment 1, and then replaced successively until the seventh through hole 7 replaces the eighth through hole 8. With the structures of the fixed valve plate 10 and the moving valve plate 20 as described above, the cooperation mode of the moving valve plate 20 and the fixed valve plate 10 when realizing the above seven functions is as Figure 34 Figure showing the cooperation of the moving valve plate 20 and the fixed valve plate 10 when running the softening function, Figure 35 Figure showing the cooperation of the moving valve plate 20 and the fixed valve plate 10 when running the softening + salt tank water replenishment function, Figure 36 Figure showing the cooperation of the moving valve plate 20 and the fixed valve plate 10 when performing the salt suction countercurrent regeneration function, Figure 37 Figure showing the cooperation of the moving valve plate 20 and the fixed valve plate 10 when performing the salt suction co-current regeneration function, Figure 38 Figure showing the cooperation of the moving valve plate 20 and the fixed valve plate 10 when in the closed function, Figure 39 Figure showing the cooperation of the moving valve plate 20 and the fixed valve plate 10 when performing the normal flushing function, Figure 40 Figure showing the cooperation of the moving valve plate 20 and the fixed valve plate 10 when performing the backwashing + raw water discharging from the water outlet function.
