Description

Technical Field

[0001] This utility model relates to the technical field of water treatment equipment, and more specifically to a multifunctional softening valve and a water softener. Background Technology

[0002] In recent years, facing different market and application demands, some users require a raw water output function during the regeneration process to solve the problem of water treatment systems running out of water during regeneration. Other users require a softening valve shut-off function to allow the softening valve to absorb salt and soak the resin before closing all channels when the system is shut down for extended periods, thus protecting the resin and preventing bacterial growth. Chinese patent ZL201420428495.3, an energy-saving multi-functional softening valve, effectively solves these problems. It is divided into 10 equal parts. The term "10 equal parts" refers to the fact that a circle with a central angle of 360° is divided into 10 equal parts, each part being 360° ÷ 10 = 36°, meaning the inlet is a 36° sector.

[0003] With the improvement of people's living standards, many villa owners in North America and Southern Europe require softening systems with high-flow-rate co-current regeneration capabilities. Low-flow-rate household softening valves can no longer meet these needs. Chinese patent ZL201420428495.3 addresses this by combining co-current and counter-current regeneration functions. However, more functions mean more divisions, resulting in a smaller outlet flow rate. To better meet market demands, there is an urgent need for softening valves with high flow rates and co-current regeneration capabilities. Currently, the 10-division design cannot effectively satisfy these high-flow-rate requirements. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a (multi-functional softening valve) that reduces the number of functional modules by designing the fixed valve plate as a nine-part structure, thereby increasing the water flow channel area and improving the outflow rate to meet the needs of high-flow-rate downstream regeneration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional softening valve, comprising a valve body, an ejector, a fixed valve plate, a movable valve plate, a valve stem, a gland, and a driving device for driving the valve stem and the movable valve plate. The valve body is provided with an inlet, an outlet, a brine inlet, a drain outlet, an upper water distribution interface, and a lower water distribution interface.

The fixed valve plate also has a closed area, which, together with the first through-hole, the second through-hole, the third through-hole, the fourth through-hole, the fifth through-hole, the sixth through-hole, the seventh through-hole, and the eighth through-hole, forms a nine-part structure on the fixed valve plate.

[0006] As a further improvement of this utility model, the fixed valve plate and the movable valve plate have the following cooperative relationship: the water inlet channel is connected to the seventh through hole, the second conductive channel is connected to the first through hole and the eighth through hole, the third conductive channel is connected to the second through hole and the third through hole, and the fourth through hole, the fifth through hole and the sixth through hole are closed; or, the water inlet channel is connected to the first through hole, the second conductive channel is connected to the second through hole and the third through hole, the third conductive channel is connected to the fourth through hole and the fifth through hole, and the sixth through hole, the seventh through hole and the eighth through hole are closed; or, the water inlet channel is connected to the second through hole, the second conductive channel is connected to the third through hole and the fourth through hole, the third conductive channel is connected to the fifth through hole and the sixth through hole, and the seventh through hole is closed. The first, eighth, and eighth through holes are closed; or, the water inlet channel is connected to the third through hole, the third conductive channel is connected to the fourth and fifth through holes, the second conductive channel is connected to the sixth through hole, and the seventh, eighth, first, and second through holes are closed; or, the water inlet channel is connected to the fourth through hole, the second conductive channel is connected to the fifth and sixth through holes, the third conductive channel is connected to the seventh through hole, and the eighth, first, second, and third through holes are closed; or, the water inlet channel is closed, the second conductive channel is connected to the seventh and eighth through holes, the third conductive channel is connected to the first and second through holes, and the third, fourth, fifth, and sixth through holes are closed.

[0007] As a further improvement of this utility model, the first through hole, the second through hole, the third through hole, the fourth through hole, the fifth through hole, the sixth through hole, the seventh through hole and the eighth through hole each occupy one equal part on the fixed valve plate, the water inlet channel occupies one equal part on the moving valve plate, and the second conducting channel and the third conducting channel each occupy two equal parts on the moving valve plate.

[0008] As a further improvement of this utility model, the first through hole and the sixth through hole are in opposite positions on the fixed valve plate, and the fourth through hole and the seventh through hole are in opposite positions on the fixed valve plate.

[0009] As a further improvement of this utility model, the closed area is set between the sixth through hole and the seventh through hole, and the closed area occupies an equal part.

[0010] As a further improvement of this utility model, the eighth through hole extends outward to have a bypass hole, and the moving valve plate is provided with an additional part, which is used to cover the bypass hole.

[0011] As a further improvement of this utility model, the additional part is disposed on the outer edge of the second conductive channel and is in the same division as the second conductive channel.

[0012] Another aspect of this utility model provides a water softener, including a resin tank, a brine tank, and a softening valve. The resin tank is equipped with an upper water distributor, a central pipe, and a lower water distributor. The upper and lower water distributors are respectively located at the upper and lower ends of the central pipe. The softening valve is installed on the resin tank. A brine valve is provided in the brine tank. The brine valve is connected to the softening valve through a connecting pipe. The structure of the softening valve is as described in any of the above. The connecting pipe is connected to the brine suction port, the upper water distributor is connected to the upper water distribution interface, and the upper end of the central pipe is connected to the lower water distribution interface.

[0013] The beneficial effects of this invention are that by designing the fixed valve plate with a nine-part structure, one functional module is reduced compared to the ten-part structure of the prior art, increasing the central angle of each part from 36° to 40° (360°÷9), effectively increasing the cross-sectional area of ​​the water flow channel. When the inlet channel and each through hole are matched, the water flow area increases by approximately 11.1% ((40°-36°) / 36°), significantly improving the outlet flow rate, which is particularly suitable for the high-flow-rate regeneration needs of villa users in North America and Southern Europe. At the same time, the nine-part structure simplifies the functional combination, reduces the internal flow resistance of the valve body, and significantly increases the water output under the same water pressure conditions, solving the problem of insufficient flow caused by too many functional modules in the prior art. Its advanced nature is reflected in maximizing flow rate with minimal structural adjustments. By optimizing the through hole layout and conduction logic, a breakthrough in flow rate is achieved while retaining the core softening function. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0025] Reference Figures 1 to 3As shown, this embodiment first provides a multi-functional softening valve according to Embodiment 1, including a valve body 30, an ejector 37, a fixed valve plate 10, a movable valve plate 20, a valve stem 61, a gland 60, and a driving device 62 for driving the valve stem 61 and the movable valve plate 20. The valve body 30 is provided with an inlet 31, an outlet 32, a brine suction port 36, a drain port 33, an upper water distribution interface 38, and a lower water distribution interface 39. The valve body 30 is also provided with an ejector inlet 34 and an ejector outlet 35 connected to the ejector 37. The fixed valve plate 10 is provided with 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, and an eighth through hole 8. The eighth through hole 8 extends outward with a bypass hole 100. The movable valve plate 20 is provided with an additional part 24. The additional part 24 is used to cover the bypass hole 100. The moving valve plate 20 is provided with an inlet channel 21, a second guiding channel 22 and a third guiding channel 23. The first through hole 1 and the sixth through hole 6 are interconnected and then connected to the lower water distribution interface 39. The second through hole 2 is connected to the jet inlet 34. The third through hole 3 is connected to the jet outlet 35. The fourth through hole 4 and the seventh through hole 7 are interconnected and then connected to the upper water distribution interface 38. The fifth through hole 5 is connected to the drain outlet 33. The eighth through hole 8 is connected to the outlet 32. The inlet channel 21 is connected to the inlet 31. The fixed valve plate 10 is also provided with a closed area, which is combined with 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 to form a nine-part structure on the fixed valve plate 10. During operation, the drive device 62 drives the valve plate 20 to rotate, and the water flow is switched through the combination of the inlet channel 21 and different through holes. When a large flow of softened water is required, the inlet channel 21 is connected to the seventh through hole 7, and the second guiding channel 22 connects the first through hole 1 and the eighth through hole 8. At this time, the raw water enters through the inlet 31, and then enters the resin tank 40 through the seventh through hole 7 and the upper water distribution interface 38 in sequence. The softened water flows out from the outlet 32 ​​through the lower water distribution interface 39, the first through hole 1, and the eighth through hole 8. In this process, the nine-part structure makes the fan-shaped opening angle of the inlet channel 21 reach 40°, which is higher than the 36° opening of the existing ten-part structure. This increases the water flow area, thereby solving the problem of insufficient flow of the ten-part structure in the background technology and realizing the function of large flow rate co-current regeneration.

[0026] Reference Figures 2 to 8As shown, further, the fixed valve plate 10 and the moving valve plate 20 have the following cooperative relationship: the water inlet channel 21 is connected to the seventh through hole 7, the second guiding channel 22 is connected to the first through hole 1 and the eighth through hole 8, the third guiding channel 23 is connected to the second through hole 2 and the third through hole 3, and the fourth through hole 4, the fifth through hole 5 and the sixth through hole 6 are closed; for the operation of producing soft water: raw water → water inlet 31 → water inlet channel 21 → seventh through hole 7 → upper water distribution interface 38 → water is evenly distributed through the upper water distributor 41 → upper part of resin tank 40 → through resin 44 or filter media for softening or filtration → lower part of resin tank 40 → lower water distributor 43 → central pipe 42 → lower water distribution interface 39 → first through hole 1 → second guiding channel 22 to the eighth through hole 8 → water outlet 32;

[0027] Alternatively, the inlet channel 21 connects to the first through hole 1, the second through channel 22 connects to the second through hole 2 and the third through hole 3, the third through channel 23 connects to the fourth through hole 4 and the fifth through hole 5, and the sixth through hole 6, the seventh through hole 7 and the eighth through hole 8 are closed; for backwashing: it is divided into the following two water paths: raw water → inlet 31, 1) → inlet channel 21 → first through hole 1 → lower water distribution interface 39 → central pipe 42 → lower water distributor 43 → lower part of resin tank 40 → backwashing of resin 44 or filter media → upper part of resin tank 40 → upper water distributor 41 → upper water distribution interface 38 → fourth through hole 4 → third through channel 23 guides to the fifth through hole 5 → wastewater is discharged from the drain outlet 33; 2) → bypass hole 100 → eighth through hole 8 → outlet 32 ​​(outlet discharges raw water).

[0028] Alternatively, the inlet channel 21 is connected to the second through hole 2, the second guiding channel 22 is connected to the third through hole 3 and the fourth through hole 4, the third guiding channel 23 is connected to the fifth through hole 5 and the sixth through hole 6, and the seventh through hole 7, the eighth through hole 8 and the first through hole 1 are closed; for downstream brine suction: raw water → inlet 31; divided into the following two water paths: 1) → inlet channel 21 → second through hole 2 → ejector inlet 34 → the negative pressure generated by the ejector 37 siphons the brine from the brine tank 51 into the ejector, and exits from the ejector. Water flows out from outlet 35 → third through hole 3 → second guiding channel 22 guides to fourth through hole 4 → upper water distribution interface 38 → upper water distributor 41 → upper part of resin tank 40 → brine passes through resin 44 to regenerate the resin → lower part of resin tank 40 → lower water distributor 43 → central pipe 42 → lower water distribution interface 39 → sixth through hole 6 → third guiding channel 23 guides to fifth through hole 5 → wastewater is discharged from drain outlet 33; 2) → bypass hole 100 → eighth through hole 8 → outlet 32 ​​(outlet discharges raw water).

[0029] Alternatively, the inlet channel 21 is connected to the third through hole 3, the third guiding channel 23 is connected to the fourth through hole 4 and the fifth through hole 5, the second guiding channel 22 is connected to the sixth through hole 6, and the seventh through hole 7, the eighth through hole 8, the first through hole 1 and the second through hole 2 are closed; to replenish water to the brine tank, it is divided into the following two water paths: raw water → inlet 31, 1) → inlet channel 21 → third through hole 3 → jet outlet 35 → brine suction port 36, which flows into the brine tank 51 through the connecting pipe 50 to replenish water to the brine tank; 2) → bypass hole 100 → eighth through hole 8 → outlet 32 ​​(the outlet is for raw water).

[0030] Alternatively, the inlet channel 21 connects to the fourth through hole 4, the second guiding channel 22 connects to the fifth through hole 5 and the sixth through hole 6, the third guiding channel 23 connects to the seventh through hole 7, and the eighth through hole 8, the first through hole 1, the second through hole 2 and the third through hole 3 are closed; for forward washing: it is divided into the following two water paths: raw water → inlet 31, 1) → inlet channel 21 → fourth through hole 4 → upper water distribution interface 38 → upper water distributor 41 → upper part of resin tank 40 → forward flushing of resin 44 or filter media → lower part of resin tank 40 → lower water distributor 43 — central pipe 42 → lower water distribution interface 39 → fixed valve plate through hole 6 → second guiding channel 22 guides to the fifth through hole 5 → wastewater is discharged from the drain outlet 33; 2) → fixed valve plate bypass hole 100 → eighth through hole 8 → outlet 32 ​​(outlet discharges raw water).

[0031] Alternatively, the inlet channel 21 can be closed, the second guiding channel 22 can connect the seventh through hole 7 and the eighth through hole 8, the third guiding channel 23 can connect the first through hole 1 and the second through hole 2, and the third through hole 3, the fourth through hole 4, the fifth through hole 5 and the sixth through hole 6 can be closed. In vacation mode, the inlet channel 21 and the through holes are not connected. By switching between six operating modes, various working conditions such as softening, backwashing, salt absorption, slow washing, fast washing, and shutdown can be achieved. When the inlet channel 21 is closed, the resin soaking function can be realized to avoid bacterial growth caused by long-term shutdown and to help solve the shutdown protection problem mentioned in the background art. Furthermore, the additional part 24 is set on the outer edge of the second guiding channel 22 and is in the same division as the second guiding channel 22. This integrated design reduces the structural complexity of the moving valve plate 20, enables simultaneous conduction and bypass control functions within a single division, and improves space utilization.

[0032] Reference Figure 2As shown in diagram a, further, 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 each occupy one equal division on the fixed valve plate 10, the water inlet channel 21 occupies one equal division on the moving valve plate 20, and the second conducting channel 22 and the third conducting channel 23 each occupy two equal divisions on the moving valve plate 20. This structural design makes the angle of each division 40°, and the flow area of ​​the water inlet channel 21 is increased by 11.1% compared with the prior art. At the same time, the dual conducting channel design can realize the synchronous switching of the two sets of through holes, improving the efficiency of operating condition switching.

[0033] Reference Figure 2 As shown in b, further, the first through hole 1 and the sixth through hole 6 are in opposite positions on the fixed valve plate 10, and the fourth through hole 4 and the seventh through hole 7 are in opposite positions on the fixed valve plate 10.

[0034] Reference Figure 2 As shown in b, further, the closed area is set between the sixth through hole 6 and the seventh through hole 7, and the closed area occupies an equal division.

[0035] Based on the aforementioned fixed valve plate 10 and movable valve plate 20, referring to Figure 9 As shown, this embodiment also provides a mirrored embodiment 2, while in cases where hard water bypass is not required, refer to... Figure 10 As shown, the bypass hole 100 has been removed. Therefore, during the backwashing station, the co-current salt suction station, the salt tank replenishment station, and the forward washing station, the raw water cannot enter the eighth through hole 8 through the bypass hole 100, and thus it no longer has the function of discharging raw water.

[0036] To assist the operation of the softening valve, this embodiment further provides a water softener, including a resin tank 40, a brine tank 51, and a softening valve. The resin tank 40 contains an upper water distributor 41, a central pipe 42, and a lower water distributor 43. The upper and lower water distributors 41 and 43 are respectively located at the upper and lower ends of the central pipe 42. The softening valve is mounted on the resin tank 40. A brine valve 52 is located in the brine tank 51 and is connected to the softening valve via a connecting pipe 50. The structure of the softening valve is as described above. The connecting pipe 50 is connected to the brine inlet 36, the upper water distributor 41 is connected to the upper water distribution interface 38, and the upper end of the central pipe 42 is connected to the lower water distribution interface 39. By integrating the softening valve with the resin tank 40, fully automatic softened water production is achieved. The cooperation of the upper and lower water distributors 41 and 43 ensures that water flows evenly through the resin layer, improving ion exchange efficiency.

[0037] This invention, by designing the valve plate into a nine-part structure, reduces one of the sub-modules while retaining the core function, increasing the flow area of ​​a single channel by 11.1%. This effectively solves the problem of insufficient flow in existing ten-part structures and meets the requirements for high-flow-rate regeneration. Through optimized valve plate fit, through-hole layout, and closed-area design, reliable switching between six operating conditions is achieved. The design of the auxiliary parts and bypass holes enhances the system's emergency response capability and sealing performance. The overall water softener solution achieves fully automated softened water production through the efficient integration of the softening valve and resin tank, suitable for high-flow-rate water usage scenarios such as villas.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
