Description

Technical Field

[0001] This invention belongs to the technical field of water treatment softening valves, and specifically provides a multi-functional water treatment softening valve. Background Technology

[0002] Modern industrial and domestic water treatment systems frequently use multi-functional control valves, especially in the field of softened water treatment. Multi-functional softening valves are now widely used to switch water flow channels and realize functions such as water production, backwashing, brine / slow washing, replenishing water to the brine tank, and forward washing.

[0003] To achieve the aforementioned multiple functions within a single valve body, various cavities or guide holes need to be incorporated into the valve body and valve disc to alter the water flow path. However, the various structures on the valve body and valve disc limit the inflow and outflow rates under normal water-making conditions. To increase the inflow and outflow rates while still satisfying these multiple functions, a common practice is to manufacture larger softening valves. However, this not only increases production costs but also hinders the installation and transportation of the softening valves.

[0004] Accordingly, there is a need in the field for a multifunctional water treatment softening valve that can solve the above problems and also has a superior structure and stronger performance. Summary of the Invention

[0005] This invention proposes a multi-functional water softening valve for water treatment. By rationally designing the internal structure and valve plates of the valve body, it realizes five functions: water production, backwashing, regeneration, forward washing, and water replenishment to the brine tank. It solves the technical problem in the prior art that a larger valve body is required to meet the water flow requirements of the softening valve, thereby increasing the manufacturing cost of the valve body. It also makes the structure more superior and the performance stronger.

[0006] The technical solution of the present invention is implemented as follows: a multi-functional water treatment softening valve, comprising a valve body, a moving valve plate and a driving device, wherein the side wall of the valve body is provided with an inlet, an outlet, a drain outlet, a water passage and a regenerator inlet; The valve body is provided with a coaxial and separated inner chamber and an outer chamber. The outer chamber is connected to the water inlet. The inner chamber includes a central drainage chamber and a fan-shaped working chamber, a backwash chamber, a regeneration chamber, a blind chamber, and a forward wash chamber distributed around the central drainage chamber. The central drainage chamber is connected to the drain outlet. A water-blocking structure is provided at the backwash chamber or the water outlet. The bottom of the valve body is provided with a first filter element interface and a second filter element interface on the same central axis. The working chamber and the forward wash chamber are respectively connected to the first filter element interface. The backwash chamber is connected to the second filter element interface. The regeneration chamber is connected to the water outlet. The water outlet is connected to the regenerant inlet. The regenerant inlet is connected to the first filter element interface. The moving valve plate is coaxially disposed above the inner cavity. The driving device is connected to the moving valve plate to drive the moving valve plate to rotate in the valve body. A central blind hole is provided at the center of the moving valve plate. The moving valve plate is provided with a fan-shaped water inlet hole, a first blind hole, a second blind hole, a drain blind hole and a third blind hole along the circumference of the central blind hole. The central blind hole is connected to the central drain cavity, and the drain blind hole is connected to the central blind hole. The central angle opposite to the first blind hole is equal to the central angle opposite to the water inlet hole, equal to the central angle opposite to the working cavity, and equal to the central angle opposite to the backwash cavity. The central angle opposite to the second blind hole is equal to the central angle opposite to the third blind hole, equal to the central angle opposite to the regeneration cavity, and equal to the central angle opposite to the forward wash cavity. The central angle opposite to the drain blind hole is equal to the central angle opposite to the blind cavity. The central angle opposite to the drain blind hole plus the central angle opposite to the second blind hole equals the central angle opposite to the first blind hole.

[0007] Beneficial effects: This invention achieves multiple functions such as water production, backwashing, regeneration, salt tank replenishment, and forward washing through the cooperation of the valve body and the moving valve plate. It optimizes the structure of the softening valve, reduces the number of fixed valve plates, simplifies the internal structure of the valve body, reduces manufacturing costs, improves performance, and is more conducive to widespread use.

[0008] In the preferred technical solution of the above-mentioned multifunctional water softening valve, the water-blocking structure is a partition beam set in the backwash chamber. The partition beam divides the backwash chamber into a first partition chamber and a second partition chamber. The first partition chamber is connected to the water outlet, and the second partition chamber is connected to the second filter element interface. A blind plate ring adapted to the first partition chamber is provided at the water inlet hole of the moving valve plate. A partition beam adapted to the top of the partition beam is provided in the second blind hole, the drain blind hole and the third blind hole.

[0009] Beneficial effects: By cooperating with the blind ring and partition beam on the cavity and moving valve plate, the connection between the water outlet and the first filter element interface can be controlled. The structure is ingenious and the operation is convenient.

[0010] In the preferred embodiment of the above-mentioned multifunctional water softening valve, the multifunctional softening valve includes a fixed valve plate one, which is coaxially fixed to the top end face of the inner cavity. A movable valve plate is located above the fixed valve plate one and rotates and seals with the fixed valve plate one. The fixed valve plate one has a central through hole one at its center. The fixed valve plate one has fan-shaped through holes one, two, three, a blind plate one, and four around the central through hole one. The central through hole one is connected to the central drainage chamber, and the through hole one is connected to the working chamber and the first filter element interface. A partition beam two is provided at the through hole two, which divides the through hole two into a first through hole and a second through hole. The first through hole is connected to the first partition chamber and the water outlet. The second through hole is connected to the second partition chamber and the second filter element interface. The through hole three is connected to the regeneration chamber and the water outlet. The blind plate one is set up vertically and vertically with the blind chamber. The through hole four is connected to the forward washing chamber and the first filter element interface.

[0011] Beneficial effects: The fixed valve plate and the moving valve plate work together to change the water flow path, avoiding the wear of the inner cavity end face caused by the moving valve plate directly rotating with the inner cavity, which would make maintenance and replacement inconvenient.

[0012] In the preferred technical solution of the above-mentioned multifunctional water softening valve, the working chamber and the first through hole each have the same central angle and the same horizontal cross-sectional area; the first partition chamber, the first through hole, and the blind ring each have the same central angle; the second partition chamber, the second through hole, and the inlet through hole each have the same central angle and the same horizontal cross-sectional area; the regeneration chamber and the third through hole each have the same central angle and the same horizontal cross-sectional area; the blind chamber and the first blind plate each have the same central angle and the same horizontal cross-sectional area; and the forward washing chamber and the fourth through hole each have the same central angle and the same horizontal cross-sectional area.

[0013] Beneficial effects: The various through holes on the fixed valve plate correspond to the various cavities of the inner chamber, allowing water passing through the fixed valve plate to directly and equally enter the inner chamber, thus improving water output efficiency.

[0014] In the preferred embodiment of the above-mentioned multifunctional water softening valve, the water-blocking structure is a valve located at the outlet. The multifunctional softening valve includes a fixed valve plate two, which is coaxially fixed to the top end face of the inner chamber. A movable valve plate is located above the fixed valve plate two and rotates and seals with the fixed valve plate two. A central through hole two is opened in the center of the fixed valve plate two. Along the circumference of the central through hole two, the fixed valve plate two is provided with a fan-shaped water passage hole one, water passage hole two, water passage hole three, blind plate two, and water passage hole four. The second central through hole is connected to the central drainage chamber, the first water through hole is connected to the working chamber and the first filter element interface, the second water through hole is connected to the backwash chamber and the second filter element interface, the third water through hole is connected to the regeneration chamber and the water outlet, the second blind plate is set correspondingly to the blind chamber, and the fourth water through hole is connected to the forward wash chamber and the first filter element interface.

[0015] In the preferred technical solution of the above-mentioned multifunctional water softening valve, the central angles and horizontal cross-sectional areas of the working chamber, the first water passage hole, and the inlet water passage hole are the same; the central angles and horizontal cross-sectional areas of the backwash chamber, the second water passage hole, and the first blind hole are the same; the central angles and horizontal cross-sectional areas of the regeneration chamber, the third water passage hole, and the second blind hole are the same; the central angles and horizontal cross-sectional areas of the blind chamber, the second blind plate, and the drainage blind hole are the same; and the central angles and horizontal cross-sectional areas of the forward wash chamber, the fourth water passage hole, and the third blind hole are the same.

[0016] Beneficial effects: The effective usable area of ​​the inlet hole and the through hole one on the fixed valve plate is the same. When the multi-functional softening valve is running normally, the raw water passing through the inlet hole can enter the tank body in equal amount through the through hole one on the fixed valve plate. When the raw water is discharged after filtration, it does not need to pass through the fixed valve plate again and can be discharged directly from the outlet on the valve body, reducing the water flow path and improving the water discharge efficiency.

[0017] In the preferred technical solution of the above-mentioned multifunctional water softening valve, the drain outlet, the water inlet, and the regenerant inlet are located on the same side wall of the valve body. The blind cavity is connected to the drain outlet, the central drain cavity is connected to the blind cavity, and the side wall of the valve body where the drain outlet is located is connected to a water guide plate. The water guide plate is provided with a water guide cavity connecting the water inlet and the regenerant inlet, a regenerant flow pipe connected to the regenerant inlet, and a drain pipe connected to the drain outlet.

[0018] Beneficial effects: By placing the drain outlet, water inlet, and regenerant inlet on the same side wall of the valve body, the valve body structure becomes compact, which is beneficial for valve body installation.

[0019] In the preferred technical solution of the above-mentioned multifunctional water softening valve, the water guide plate is provided with a first water guide hole communicating with the water outlet and a second water guide hole communicating with the regenerant inlet. The water guide plate is also provided with a cover plate, and a water guide groove is provided in the cover plate. The water guide groove connects the first water guide hole and the second water guide hole. The first water guide hole, the water guide groove and the second water guide hole form a water guide cavity connecting the water outlet and the regenerant inlet. The regenerant flow pipe is connected to the second water guide hole, and a jet port is provided in the second water guide hole.

[0020] Beneficial effects: During the regeneration process, the raw water at the inlet enters the second guide hole through the jet port and mixes with the regenerant drawn in by the regenerant flow pipe. Then, it enters the tank connected to the valve body through the regenerant inlet and the first filter element interface, where it undergoes ion exchange regeneration with the ion exchange resin in the tank. The jet port allows for a small volume of raw water but a high pressure, increasing the flow rate and facilitating the absorption of the regenerant to fully mix with the raw water. This ensures that the mixed water reacts fully in the tank.

[0021] In the preferred embodiment of the above-mentioned multifunctional water treatment softening valve, the working chamber is connected to the forward washing chamber.

[0022] Beneficial effects: Without affecting functionality, it reduces the use of materials and further lowers production costs.

[0023] In the preferred technical solution of the above-mentioned multifunctional water softening valve, the sum of the central angles of the working chamber, backwash chamber, regeneration chamber, blind chamber, and forward wash chamber is equal to 360°. The central angle of the working chamber is less than 120° of the central angle of the backwash chamber. The central angle of the forward wash chamber is equal to the central angle of the regeneration chamber. The central angle of the blind chamber plus the central angle of the forward wash chamber equals the central angle of the working chamber.

[0024] Beneficial effects: Under the above conditions, the central angle of each cavity in the valve body can be adjusted as needed, which is beneficial to the optimization of the internal structure of the valve body. Attached Figure Description

[0033] like Figure 6 and Figure 8As shown, the fixed valve plate 2 is engaged with the valve body 1 by two pairs of support legs and is located above the inner cavity 16. The horizontal cross-sectional area of ​​the fixed valve plate 2, excluding the support legs, is the same as the horizontal cross-sectional area of ​​the inner cavity 16. The fixed valve plate 2 is stacked above the inner cavity 16 and is sealed in a corresponding manner with the inner cavity 16.

[0035] When the fixed valve plate 2 is installed inside the valve body 1, the central through hole 20 is connected to the central drain chamber 160; the first through hole 21 is connected to the working chamber 161 and the first filter element interface 18; the first through hole 91 is connected to the first partition chamber 61 and the outlet 12; the second through hole 92 is connected to the second partition chamber 62 and the second filter element interface 19; the third through hole 23 is connected to the regeneration chamber 163 and the water outlet 14; the blind plate 24 is correspondingly set above and below the blind chamber 164; the fourth through hole 25 is connected to the positive washing chamber 165 and the first filter element interface 18.

[0036] like Figure 7 As shown, a central blind hole 30 is provided at the center of the moving valve plate 3. Around the central blind hole 30, the moving valve plate 3 has fan-shaped annular water inlet holes 31, a first blind hole 32, a second blind hole 33, a drain blind hole 34, and a third blind hole 35. A blind plate ring 7, adapted to the first partition cavity 61, is provided at the water inlet hole 31. The central angles of the first partition cavity 61 and the blind plate ring 7 are the same.

[0038] In this embodiment, the central angle opposite to the working chamber 161 is equal to the central angle opposite to the backwash chamber 162, which is 105°; the central angle opposite to the regeneration chamber 163 is equal to the central angle opposite to the forward wash chamber 165, which is 45°; and the central angle opposite to the blind chamber 164 is 60°.

[0039] When the moving valve plate 3 is installed above the fixed valve plate 2, its central blind hole 30 is connected to the central drain chamber 160 through the central through hole 20.

[0040] The present invention provides a multi-functional water softening valve for water treatment, which has a water production mode, a backwash mode, a regeneration mode, a forward wash mode, and a brine tank injection mode. The moving valve plate 3 is driven to rotate by the driving device 4, so that the moving valve plate 3 and the fixed valve plate 2 cooperate to achieve switching operation of different modes.

[0041] like Figure 8 and Figure 9 As shown, in water production mode, the inlet hole 31 of the moving valve plate 3 is vertically connected to the through hole 21 of the fixed valve plate 2, the first blind hole 32 is vertically connected to the through hole 22, the second blind hole 33 is vertically connected to the through hole 33, the drain blind hole 34 is vertically connected to the blind plate 24, and the third blind hole 35 is vertically connected to the through hole 45. Raw water enters the outer chamber 17 of the valve body 1 from the inlet 11, and passes through the inlet hole 31, through hole 21, working chamber 161, and first filter interface 18 in sequence to enter the tank connected to the valve body 1. The tank is equipped with materials such as ion exchange resin for softening water. The softened water flows along the central pipe of the tank, passes through the second filter interface 19, the second partition chamber 62, and the second through hole 92 in sequence to enter the first blind hole 32, and then passes over the partition beam 29 through the first through hole 91 to enter the first partition chamber 61, and finally flows out from the outlet 12, realizing the water production function of the multi-functional water softening valve.

[0042] In backwash mode, the drive device 4 drives the moving valve plate 3 to rotate counterclockwise by 105° (relative to the position of the moving valve plate 3 in water production mode), so that the water inlet through hole 31 on the moving valve plate 3 is vertically connected to the second through hole 92 on the fixed valve plate 2, the blind plate ring 7 is vertically connected to the first through hole 91, the first blind hole 32 is vertically connected to the third through hole 23 and the blind plate 24, the second blind hole 33 is vertically connected to the fourth through hole 25, and the drain blind hole 34 and the third blind hole 35 are vertically connected to the first through hole 21. Water enters the outer chamber 17 of the valve body 1 from the water inlet 11. Inside, the water flows through the inlet hole 31, the second through hole 92, the second partition chamber 62, and the second filter element interface 19 into the central tube of the tank connected to the valve body 1, rinsing the ion exchange resin in the tank from bottom to top. The backwash wastewater enters the working chamber 161 from the first filter element interface 18, and then passes through the through hole 21, the drain blind hole 34, the central blind hole 30, and the central through hole 20 into the central drain chamber 160. Finally, it enters the drain pipe 54 through the drain outlet 13 and is discharged, thus realizing the backwashing function of the multi-functional water treatment softening valve.

[0043] The regenerant flow pipe 53 is connected to a salt tank, and a valve is installed between the regenerant flow pipe 53 and the salt tank. In regeneration mode, when the valve between the regenerator flow pipe 53 and the brine tank is opened, the drive device 4 drives the moving valve plate 3 to rotate 210° (relative to the position of the moving valve plate 3 in water production mode), so that the water inlet hole 31 on the moving valve plate 3 corresponds vertically to the through hole 23 and blind plate 24 on the fixed valve plate 2, the first blind hole 32 corresponds vertically to the through hole 25 and part of the through hole 21, the second blind hole 33 corresponds vertically to the remaining part of the through hole 21, and the drain blind hole 34 and the third blind hole 35 correspond vertically to the through hole 22. In addition, the partition beam 8 in the drain blind hole 34 and the third blind hole 35 corresponds vertically to the partition beam 9 at the through hole 22 and is sealed tightly. Water enters the outer chamber 17 of the valve body 1 from the inlet 11 and passes through the water inlet hole 31, through hole 23, regeneration chamber 163, water outlet 14, first guide hole 51, and guide hole in sequence. The tank and the second water guide hole 52, through the action of the jet port 56, mix with the regenerant water drawn in by the regenerant flow pipe 53. As an example, the regenerant water is brine. Then, it enters the tank connected to the valve body 1 through the regenerant inlet 15 and the first filter element interface 18. After undergoing an ion exchange reaction with the ion exchange resin in the tank, it goes up from the central pipe of the tank, enters the second partition chamber 62 through the second filter element interface 19, and enters the drainage blind hole 34 through the second through hole 92. The partition beam 8 in the drainage blind hole 34 and the third blind hole 35 prevents water from overflowing into the first through hole 91. The water enters the central blind hole 30, the central through hole 20, and the central drainage chamber 160 in sequence through the drainage blind hole 34, and finally enters the drainage pipe 54 through the drain port 13 and is discharged, realizing the regeneration process of the water treatment multi-functional softening valve.

[0044] In the forward washing mode, the drive device 4 drives the moving valve plate 3 to rotate counterclockwise by 255° (relative to the position of the moving valve plate 3 in the water production mode), so that the water inlet hole 31 on the moving valve plate 3 corresponds vertically to the through hole 25 and blind plate 24 on the fixed valve plate 2, the first blind hole 32 corresponds vertically to the through hole 21, the second blind hole 33 and the drain blind hole 34 correspond vertically to the through hole 22, and the first barrier beam in the second blind hole 33 and the drain blind hole 34 corresponds vertically to the second partition beam 9 at the through hole 22 and is sealed and fitted, and the third blind hole 35 corresponds vertically to the through hole 33. Water enters the outer chamber 17 of the valve body 1 from the water inlet 11 and passes through... Water enters the tank connected to valve body 1 through inlet hole 31, through hole 25, forward washing chamber 165, and first filter element interface 18. It flows from top to bottom through ion exchange resin for forward washing, and then enters the second partition chamber 62 through the second filter element interface 19 from the central tube. It then enters the drain blind hole 34 through the second through hole 92. The baffle beam in the second blind hole 33 and the drain blind hole 34 prevents water from turning into the first through hole 91. Finally, the water enters the central blind hole 30, the central through hole 20, and the central drain chamber 160 through the drain blind hole 34 in sequence, and finally enters the drain pipe 54 through the drain outlet 13 and is discharged, realizing the forward washing function of the multi-functional water treatment softening valve.

[0045] When water needs to be added to the brine tank, in addition to the regeneration mode, the valve between the regenerant flow pipe 53 and the brine tank can be opened during either the water production mode or the forward washing mode as needed. Water flows through the first filter element interface 18, the regenerant inlet 15 and the regenerant flow pipe 53 into the brine tank for water injection, realizing the water injection function of the multi-functional water treatment softening valve. Specific Implementation Example 2 like Figures 10 to 13 As shown, unlike Embodiment 1, a second valve is provided at the outlet 12. The inner chamber 16 of the valve body 1 includes a central drainage chamber 160 and fan-shaped working chambers 161, backwash chamber 162, regeneration chamber 163, blind chamber 164, and forward wash chamber 165 distributed circumferentially along the central drainage chamber 160. There is no partition beam in the backwash chamber 162, and the backwash chamber 162 is directly connected to the outlet 12 and the second filter element interface 19.

[0047] The fixed valve plate 2 has a central through hole 20. The fixed valve plate 2 has fan-shaped through holes 21, 22, 23, a blind plate 24, and 25 arranged around the central through hole 20. There is no partition beam 2 at through hole 22. Through hole 22 is connected to the backwash chamber 162 and the second filter element interface 19.

[0048] A central blind hole 30 is provided at the center of the moving valve plate 3. Along the circumference of the central blind hole 30, the moving valve plate 3 has a fan-shaped water inlet hole 31, a first blind hole 32, a second blind hole 33, a drain blind hole 34, and a third blind hole 35. There is no blind plate ring at the water inlet hole 31, and there is no partition beam in the second blind hole 33, the drain blind hole 34, and the third blind hole 35.

[0049] The working chamber 161, through hole 1 21 and water inlet through hole 31 each have the same central angle and the same horizontal cross-sectional area. The backwash chamber 162, through hole 2 22 and the first blind hole 32 each have the same central angle and the same horizontal cross-sectional area. The regeneration chamber 163, through hole 3 23 and the second blind hole 33 each have the same central angle and the same horizontal cross-sectional area. The blind chamber 164, blind plate 24 and drainage blind hole 34 each have the same central angle and the same horizontal cross-sectional area. The forward wash chamber 165, through hole 4 25 and the third blind hole 35 each have the same central angle and the same horizontal cross-sectional area.

[0050] When in water production mode, valve 2 connected to outlet 12 is opened, the inlet hole 31 of moving valve plate 3 is connected vertically to the through hole 21 of fixed valve plate 2, the first blind hole 32 is connected vertically to the through hole 22, the second blind hole 33 is connected vertically to the through hole 33, the drain blind hole 34 is connected vertically to the blind plate 24, and the third blind hole 35 is connected vertically to the through hole 45. Raw water enters the outer chamber 17 of valve body 1 from inlet 11, and passes through inlet hole 31, through hole 21, working chamber 161, and first filter interface 18 in sequence into the tank connected to valve body 1. The tank is equipped with materials such as ion exchange resin for softening water. The softened water flows along the central tube of the tank, passes through the second filter interface 19 and backwash chamber 162 in sequence, and finally flows out from outlet 12, realizing the water production function of the multi-functional softening valve.

[0051] In backwash mode, valve 2 connected to outlet 12 is closed, and drive device 4 drives moving valve plate 3 to rotate counterclockwise 105° (relative to the position of moving valve plate 3 in water production mode), so that the water inlet through hole 31 on moving valve plate 3 is vertically connected to the second through hole 92 on fixed valve plate 2, the first blind hole 32 is vertically connected to the through hole 23 and blind plate 24, the second blind hole 33 is vertically connected to the through hole 25, and the drain blind hole 34 and the third blind hole 35 are vertically connected to the through hole 21. Water enters the outer chamber 1 of valve body 1 from inlet 11. The water flows through the inlet hole 31, through hole 22, backwash chamber 162, and second filter element interface 19 into the central tube of the tank connected to the valve body 1, rinsing the ion exchange resin in the tank from bottom to top. The backwash wastewater enters the working chamber 161 from the first filter element interface 18, and then passes through through hole 21, drain blind hole 34, central blind hole 30, and central through hole 20 into the central drain chamber 160. Finally, it enters the drain pipe 54 through the drain outlet 13 and is discharged, thus realizing the backwash function of the multi-functional water treatment softening valve.

[0052] In regeneration mode, valve one between the regenerator flow pipe 53 and the brine tank is opened, and valve two connected to the outlet 12 is closed. The drive device 4 drives the moving valve plate 3 to rotate 210° (relative to the position of the moving valve plate 3 in water production mode), so that the water inlet hole 31 on the moving valve plate 3 corresponds vertically to the through hole three 23 and the blind plate 24 on the fixed valve plate 2, the first blind hole 32 corresponds vertically to the through hole four 25 and part of the through hole one 21, the second blind hole 33 corresponds vertically to the remaining part of the through hole one 21, and the drain blind hole 34 and the third blind hole 35 correspond vertically to the through hole two 22. Water enters the outer chamber 17 of the valve body 1 from the inlet 11 and passes through the water inlet hole 31, through hole three 23, regeneration chamber 163, outlet 14, and the first... The water guide hole 51, water guide groove, and second water guide hole 52, through the action of the jet port 56 at the second water guide hole 52, mix with the regenerant water drawn in by the regenerant flow pipe 53. As an example, the regenerant water is brine. Then, it enters the tank connected to the valve body 1 through the regenerant inlet 15 and the first filter element interface 18. After undergoing an ion exchange reaction with the ion exchange resin in the tank, it goes up from the central pipe of the tank, enters the backwash chamber 162 through the second filter element interface 19, and then passes through the second through hole 22, the drain blind hole 34, the central blind hole 30, and the central through hole 20 in sequence to enter the central drain chamber 160. Finally, it enters the drain pipe 54 through the drain port 13 and is discharged, realizing the regeneration process of the multi-functional softening valve.

[0053] In the forward washing mode, valve 2 connected to outlet 12 is closed. Drive device 4 drives moving valve plate 3 to rotate counterclockwise by 255° (relative to the position of moving valve plate 3 in water production mode), so that the water inlet through hole 31 on moving valve plate 3 corresponds vertically to the through hole 25 and blind plate 24 on fixed valve plate 2, the first blind hole 32 corresponds vertically to the through hole 21, the second blind hole 33 and the drain blind hole 34 correspond vertically to the through hole 22, and the third blind hole 35 corresponds vertically to the through hole 23. Water enters the outer chamber 17 of valve body 1 from inlet 11. The water flows through the inlet hole 31, through hole 25, forward wash chamber 165, and first filter element interface 18 into the tank connected to the valve body 1. It flows from top to bottom through the ion exchange resin for forward wash, and then from the central tube through the second filter element interface 19 into the backwash chamber 162. It then enters the drain blind hole 34 through through hole 22. Finally, the water enters the central blind hole 30, central through hole 20, and central drain chamber 160 through the drain blind hole 34 in sequence, and is discharged through the drain outlet 13 into the drain pipe 54, thus realizing the forward wash of the multi-functional softening valve.

[0054] When water needs to be added to the brine tank, in addition to the regeneration mode, the valve between the regenerant flow pipe 53 and the brine tank can be opened during either the water production mode or the forward washing mode as needed. Water flows through the first filter element interface 18, the regenerant inlet 15 and the regenerant flow pipe 53 into the brine tank for water injection, realizing the water injection function of the multi-functional water treatment softening valve.

[0055] It should be noted that although a fixed valve plate is provided in the valve body in both Embodiment 1 and Embodiment 2, this is not a limitation on the structure of the softening valve. For example, in other embodiments, the fixed valve plate can be omitted, and the moving valve plate can directly rotate and cooperate with the inner cavity to achieve the above-mentioned multiple functions.

[0056] It should also be noted that although the water inlet, regenerator inlet and drain outlet are located on the same side wall of the valve body in Embodiments 1 and 2, this is not a limitation on the location of the water inlet, regenerator inlet and drain outlet. For example, in other embodiments, the water inlet, regenerator inlet and drain outlet can be located on different side walls of the valve body.

[0057] It should also be noted that although the positive rinsing chamber and the working chamber in the above embodiments one and two are two separate chambers, this is not a limitation on the structure of the positive rinsing chamber and the working chamber. For example, in other embodiments, in order to reduce manufacturing costs, the positive rinsing chamber and the working chamber can be connected, while other structures remain unchanged, and the rotation angle of the active valve plate remains unchanged in each mode.

[0058] It should also be noted that although the central angle subtended by the working cavity in Embodiment 1 and Embodiment 2 is equal to the central angle subtended by the backwash cavity (105°), the central angle subtended by the regeneration cavity is equal to the central angle subtended by the forward wash cavity (45°), and the central angle subtended by the blind cavity is equal to 60°, this is not the only angle subtended by each cavity. For example, in other embodiments, the central angle subtended by the working cavity is equal to the central angle subtended by the backwash cavity (110°), the central angle subtended by the regeneration cavity is equal to the central angle subtended by the forward wash cavity (30°), and the central angle subtended by the blind cavity is equal to 80°. The requirement is that the sum of the central angles subtended by the working cavity, backwash cavity, regeneration cavity, blind cavity, and forward wash cavity equals 360°, the central angle subtended by the working cavity is less than 120° of the central angle subtended by the backwash cavity, the central angle subtended by the forward wash cavity equals the central angle subtended by the regeneration cavity, and the sum of the central angles subtended by the blind cavity and the forward wash cavity equals the central angle subtended by the working cavity.

[0059] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
