Description

Technical Field

[0001] The present application relates to the technical field of water softening equipment, and in particular to a water softening equipment softening valve and a water softening equipment softening system. Background Art

[0002] A household softening system is generally composed of a control system, an operating system and a regeneration system. The control system includes a control valve, the operating system includes a softening filter material, a resin tank and a flow channel structure, and the regeneration system includes a salt box and a salt valve structure. The working principle is that hard water flows through the flow channel structure in a certain direction and contacts the softening filter material in the resin tank. Through the exchange reaction, the calcium, magnesium and other ions in the hard water are replaced to achieve water softening. The filter material gradually fails from the water inlet direction of the resin tank to the water outlet direction until the water outlet is greater than the failure standard value. After the softening filter material fails, the filter material needs to be regenerated and restored. The softening salt in the salt box is dissolved into saturated brine, and the regeneration liquid is injected into the resin tank to exchange the adsorbed calcium and magnesium ions and discharge them again to regenerate the filter material.

[0003] Traditional water softening equipment (such as household water softeners) control valves are mostly multifunctional softening valves, including flat sealing valves and piston valves; the valve has multiple flow channels inside, and the valve core is rotated to control the flow channel switching to achieve the softening operation, flushing, salt absorption regeneration, water replenishment and other functions of the water softener. The multifunctional softening valve mainly realizes the switching of multiple flow channels by rotating the fixed plate and the moving plate with holes inside the valve core to cooperate with the valve body flow channel. It generally has flow channels for operation, regeneration salt absorption, backwashing, forward washing, water replenishment and other positions. When regenerating salt absorption, the moving plate is rotated to cooperate with the fixed plate to realize water flow through the ejector. After absorbing salt water, it enters the resin tank through the valve body flow channel of the multi-way valve to form a regeneration flow channel and realize the regeneration position.

[0004] However, in the actual regeneration process, the sodium ion utilization rate of the regeneration liquid is constantly changing due to changes in the regeneration conditions. When the regeneration conditions deviate from the optimal operating conditions, the sodium ion utilization rate will decrease, resulting in a decrease in the performance of the entire machine, an increase in salt consumption, and low regeneration efficiency. Summary of the invention

[0028] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] In order to explain in detail the technical principle and effect of the softening valve of the water softening equipment and the softening system of the water softening equipment in the present application, the entire drinking water softening process, the composition of the softening system of the water softening equipment and its working mode will be explained in detail below in conjunction with the accompanying drawings. The numbers and component names appearing in the accompanying drawings are as follows: 1. Transmission gear; 2. Drain outlet; 3. Fixed valve plate; 4. Motor; 5. Main valve body; 6. Water inlet; 7. Resin tank; 8. Center pipe; 9. Softening filter material; 10. Lower water distributor; 11. Salt valve; 12. Salt box; 13. Upper water distributor; 14. Salt absorption pipe; 15. Mixer; 16. Moving valve plate; 17. Valve housing; 18. Water outlet; 19. Regeneration flow channel.

[0030] Specific as Figure 1 As shown, the softening valve of the water softening equipment (referred to as the softening valve) is used in conjunction with the softening system of the water softening equipment (referred to as the softening system). The water softening system comprises a salt box 12, a salt valve 11, and a resin tank 7; the salt box 12 is used to store dissolved softening salt; the salt valve 11 is connected to a mixer 15, and is used to absorb salt solution and replenish water to the salt box 12; the resin tank 7 is connected to the softening valve, and the resin tank 7 is filled with softening filter material 9, which forms a complete and sealed flow channel system with the softening valve through the upper water distributor 13, the lower water distributor 10 and the central pipe 8; the upper water distributor 13 is placed on the upper part of the resin tank 7 and is connected to the softening valve at the same time, and the upper water distributor 13 is provided with an opening smaller than the diameter of the softening filter material 9, so that the raw water flowing out of the softening valve is dispersed during operation and evenly contacts with the softening filter material 9 in the resin tank 7. During regeneration, the softened filter material 9 is prevented from being discharged and lost, and the regeneration wastewater is collected and input into the softening valve; the lower water distributor 10 has an opening smaller than the diameter of the softened filter material 9, is placed at the bottom of the resin tank 7 and is connected to the central pipe 8. During operation, the lower water distributor 10 evenly collects the soft water passing through the softened filter material 9 and inputs it into the central pipe 8, and during regeneration, evenly disperses the regeneration liquid flowing out of the central pipe 8 and uniformly contacts and regenerates the softened filter material 9; the central pipe 8 is connected to the softening valve, collects soft water during operation and inputs it into the softening valve, and during regeneration, outputs the regeneration liquid from the softening valve into the lower water distributor 10.

[0031] like Figure 2 As shown, the present application provides a new softening valve for softening water equipment, including a main valve body 5, a drive assembly 1-4 and a regeneration flow channel adjustment assembly 3-16.

[0032] The driving component 1-4 and the regeneration flow channel regulating component 3-16 are built into the main valve body 5. A plurality of regeneration flow channels are arranged in the main valve body 5. The regeneration flow channel regulating component adjusts the regeneration flow channels conducted in the main valve body 5 under the drive of the driving component 1-4. The flow areas of different conducted regeneration flow channels are different.

[0033] like Figure 1 As shown, a variety of flow channels are arranged in the main valve body 5, mainly including an operating flow channel and a regeneration flow channel. The operating flow channel is used to introduce raw water into the softening system for raw water softening, and then guide the softened water to the user's home. The regeneration flow channel is used to guide the regeneration liquid injected from the outside into the softening system when the softening system is in the regeneration position, so as to regenerate the softening filter material in the softening system, for example Figure 1 Here, the main valve body 5 is provided with a plurality of regeneration flow channels, and the flow areas of the regeneration flow channels with different conductions are different, that is, when different regeneration flow channels are conducted, the flow rates of the regeneration liquid flowing through the regeneration flow channels are different, so the flow rates of the regeneration liquid injected into the softening filter material storage container (resin tank 7) through the conducted regeneration flow channels are different. In other words, the flow rate of the regeneration liquid injected into the softening filter material storage container can be controlled by adjusting the conduction of different regeneration flow channels in the main valve body 5.

[0034] The drive component 1-4 is used to drive the regeneration flow channel adjustment component 3-16 for adjustment. The drive component 1-4 can be understood as giving a "force" to the regeneration flow channel adjustment component 3-16 so that it can be adjusted according to the needs of the current application scenario. Specifically, the drive component 1-4 may include a drive motor and a transmission unit. The drive motor rotates, and the force is applied to the regeneration flow channel adjustment component 3-16 through the transmission unit. The drive motor can be a stepper motor. In order to achieve precise adjustment, multiple stepper motors can be used for coordinated drive. The traditional unit can be a transmission gear.

[0035] The regeneration flow channel regulating component 3-16 is used to adjust the regeneration flow channel that is connected in the main valve body 5 under the drive of the driving component. Specifically, the regeneration flow channel regulating component 3-16 can be understood as the "switch" of each regeneration flow channel. When it is turned on, the corresponding regeneration flow channel is connected, and the regeneration liquid injected from the outside enters the softening filter material storage container through the connected regeneration flow channel, and contacts with the softening filter material to achieve regeneration; when it is closed, the corresponding regeneration flow channel is closed, and the regeneration liquid injected from the outside needs to enter the softening filter material storage container through other connected regeneration flow channels. The flow area of ​​different connected regeneration flow channels is different. The regeneration flow channel regulating component 3-16 can adjust the flow channel hole under the drive of the driving component 1-4, and specifically can adjust the opening of the conducting flow channel hole, for example, the opening is 20%, 40%, 60%, 100%. It is also possible to select a certain flow channel hole in the pre-opened flow channel holes as the conducting flow channel hole, and the flow area of ​​these pre-opened flow channel holes is different. Furthermore, the conductive flow channel holes can be adjusted by setting a movable valve assembly and a fixed valve assembly to form different conductive regeneration flow channels in the main valve body 5, wherein the movable valve assembly operates under the drive of the driving assembly, and specifically can be rotated or translated, and the fixed valve assembly remains fixed, and flow channel holes are opened on the fixed valve assembly and the movable valve assembly. After the movable valve assembly and the fixed valve assembly move relative to each other, the coordinated conductive flow channel holes of the two are adjusted to form different conductive regeneration flow channels in the main valve body 5.

[0036] The softening valve of the water softening equipment of the present application includes a main valve body, a driving component and a regeneration flow channel regulating component. A plurality of regeneration flow channels are arranged in the main valve body. The regeneration flow channels are driven by the driving component to drive the regeneration flow channel regulating component to adjust the conductive regeneration flow channels, so as to adjust the flow rate of the regeneration liquid entering the softening filter material through the softening valve of the water softening equipment, thereby realizing the regeneration liquid flow control during the regeneration process, avoiding the low regeneration efficiency due to the fixed regeneration liquid flow rate, and supporting efficient regeneration.

[0037] like Figure 3 As shown, in one embodiment, the regeneration flow channel adjustment component 3-16 includes a movable valve component 16 and a fixed valve component 3, and flow channel holes are provided on the movable valve component 16 and the fixed valve component 3. The driving component 1-4 drives the movable valve component 16 to move, and adjusts the flow channel holes that cooperate with each other between the movable valve component 16 and the fixed valve component 3 to form regeneration flow channels with different conductivities in the main valve body 5.

[0038] Both the moving valve assembly 16 and the fixed valve assembly 3 are provided with flow channel holes. For example, the moving valve assembly 16 can be provided with flow channel holes A, B, and C, and the fixed valve assembly 3 can be provided with flow channel holes a, b, and c. Under the cooperation of Aa, the regeneration flow channel regulating assembly 3-16 forms a conductive flow channel hole x, that is, a conductive regeneration flow channel X is formed in the valve body; under the cooperation of Bb, the regeneration flow channel regulating assembly 3-16 forms a conductive flow channel hole y, that is, a conductive regeneration flow channel Y is formed in the valve body; under the cooperation of Cc, the regeneration flow channel regulating assembly 3-16 forms a conductive flow channel hole z, that is, a conductive regeneration flow channel Z is formed in the valve body. The above-mentioned flow channel holes are all used to form the regeneration flow channel. In addition, in the operation process of the softening system, in addition to the regeneration station (salt absorption), there are also four stations of backwashing, water replenishment, forward washing and operation. These four stations are provided with corresponding flow channel holes in the moving valve assembly 16 and the fixed valve assembly 3 to form corresponding flow channels in the entire main valve body 5.

[0039] Furthermore, a plurality of special-shaped flow channel holes are provided on the movable valve assembly 16 and the fixed valve assembly 3. The shapes of these flow channel holes are not limited, and the required number of flow holes can be reasonably provided according to the actual area of ​​the movable valve assembly 16 and the fixed valve assembly 3. Generally speaking, there are salt absorption flow channel holes 1 and salt absorption flow channel holes 2 corresponding to the regeneration station (salt absorption), and there are also backwash flow channel holes, water replenishment flow channel holes, forward wash flow channel holes, and operation flow channel holes. In practical applications, due to the limited area on the movable valve assembly 16 and the fixed valve assembly 3, if all flow channel holes of the same shape are used, it may not meet the design requirements (for example, all circular ones are used), and special-shaped ones can meet the design requirements of various flow channel shapes.

[0040] In one embodiment, a first movable valve flow channel hole and a second movable valve flow channel hole are provided on the movable valve assembly 16, and a first fixed valve flow channel hole and a second fixed valve flow channel hole are provided on the fixed valve assembly 3. The first movable valve flow channel hole cooperates with the first fixed valve flow channel hole to form a first conducting flow channel hole, and the second movable valve flow channel hole cooperates with the second fixed valve flow channel hole to form a second conducting flow channel hole. The flow area of ​​the first conducting flow channel hole is different from the flow area of ​​the second conducting flow channel hole.

[0041] In this embodiment, two flow channel holes are respectively provided on the movable valve assembly 16 and the fixed valve assembly 3, and the provided flow channel holes cooperate to form a stable first conductive flow channel hole and a second conductive flow channel hole. Since the flow areas of the first conductive flow channel hole and the second conductive flow channel hole are different, conductive regeneration channels with different flow areas can be formed in the main valve body 5. Here, selecting two conductive flow channel holes can meet the function of adjusting the flow rate of the regeneration liquid injected into the softening filter material while opening as few and independent flow channel holes as possible to meet the needs in specific scenarios. Furthermore, the movable valve assembly 16 and the fixed valve assembly 3 can be a movable valve plate and a fixed valve plate, respectively.

[0042] like Figure 3As shown, in one embodiment, the softening valve of the water softening equipment further includes a mixer 15, which is provided with a water inlet and outlet and a salt absorption port, the water inlet and outlet of the mixer 15 are connected to the regeneration water outlet of the main valve body 5, and the salt absorption port of the mixer 15 is connected to an external salt absorption pipe.

[0043] The mixer 15 is specifically used to absorb a certain concentration of regeneration liquid (brine) from the outside, mix the absorbed regeneration liquid with soft water, and then inject it into the main valve body 5, and then inject it into the storage container of the softened filter material through the regeneration flow channel in the main valve body 5, so as to contact with the softened filter material for regeneration. In addition, the mixer 15 can also inject the water output from the water outlet of the main valve body 5 into the external salt absorption pipe when in the water replenishment station, and the water then enters the external salt tank to achieve the regeneration liquid concentration adjustment and regeneration liquid water replenishment.

[0044] In practical applications, such as Figure 1 As shown, the softening valve of the water softening equipment of the present application is a planar multi-way valve structure, including a main valve body 5, a valve housing, a motor 4, a transmission gear 1, a moving valve plate 16, a fixed valve plate 3, and a mixer 15; the valve body is provided with a water inlet 6, a water outlet 18, a sewage outlet 2, a salt absorption pipe 14 and a regeneration flow channel 19. The main valve body 5 has multiple flow channels, and the inlet and outlet water are connected to the fixed valve plate 3, the mixer 15 and the softening system; the valve shell protects the isolation valve body 5, the motor 4, the gear 1, the valve plate, etc.; the motor 4 is connected to the power supply and the rotation signal through the electric control board, and the valve plate is rotated by powering the gear 1; the movable valve plate 16 has a plurality of special-shaped flow channel holes, which are in series with the fixed valve plate 3; the fixed valve plate 3 has a plurality of special-shaped flow channel holes, and the flow channel holes are connected to the flow channel of the valve body 5 and the flow channel of the movable valve plate 16, and the flow channel holes on the fixed valve plate 3 are connected or closed by rotating the movable valve plate 16; the mixer 15 has a water inlet and outlet and a salt absorption port, the water inlet and outlet are connected to the valve body 5, and the salt absorption port is connected to the salt absorption pipe 14, and the mixer 15 uses the siphon principle or a pump to suck the mixed brine to configure the regeneration liquid; the regeneration flow channel 19 is an inherent flow channel of the valve body 5, and there are 2 or more flow channels, and the flow areas of different regeneration flow channels are different. The flow channel cooperates with the multiple regeneration flow channel holes of the fixed valve plate 3.

[0045] In one of the embodiments, the softening valve of the soft water equipment further includes a controller, and the connected regeneration flow channel includes a first regeneration flow channel and a second regeneration flow channel, and the flow area of ​​the first regeneration flow channel is larger than the flow area of ​​the second regeneration flow channel; the controller is used to control the mixer to mix a regeneration liquid with a lower concentration and control the drive component to drive the regeneration flow channel regulating component to move in the front section of the regeneration station to form a first regeneration flow channel in the main valve body; in the rear section of the regeneration station, the controller is used to control the mixer to mix a regeneration liquid with a higher concentration and control the drive component to drive the regeneration flow channel regulating component to move to form a second regeneration flow channel in the main valve body.

[0046] The controller is used to control the regeneration flow channel that is turned on at different stages of the regeneration station. Specifically, in the front section of the regeneration station, the mixer mixes the regeneration liquid with the raw water into a regeneration liquid with a lower concentration, and a first regeneration flow channel is formed in the main valve body. The flow area of ​​the first regeneration flow channel is large, that is, the regeneration liquid is currently injected into the softening filter material storage container in a low concentration and large flow manner to regenerate with the softening filter material; in the back section of the regeneration station, the mixer mixes the regeneration liquid with the raw water into a regeneration liquid with a higher concentration, and a second regeneration flow channel is formed in the main valve body. The flow area of ​​the second regeneration flow channel is small, that is, the regeneration liquid is currently injected into the softening filter material storage container in a high concentration and low flow manner to regenerate with the softening filter material. Here, according to different stages of the regeneration station, different concentrations and flow rates of regeneration liquid are used to regenerate the softening filter material, so that the softening filter material regeneration always maintains the optimal ion concentration environment, improving the utilization rate of the regeneration liquid and the regeneration degree of the softening filter material. The judgment of the front section and the back section of the regeneration station can be specifically made by detecting the salt utilization rate in the regeneration liquid. When the salt utilization rate decreases, it is determined to enter the back section of the regeneration station, that is, the time interval from the start of the regeneration station to the decrease of the salt utilization rate is the front section, and the time interval from the decrease of the salt utilization rate to the final completion of the softening filter material regeneration is the back section.

[0047] Furthermore, when applied to the entire softening system, the controller can also be used to coordinate the entire softening system to adjust the operation, regeneration (salt absorption), backwashing, forward washing and water replenishment stations. The softening system sets the corresponding programs for different water qualities in advance according to the amount of softening filter material, sets the water quality parameters before use, and the amount of water that can be used is fixed, with time and flow as the judgment conditions. There are many judgment processes, such as starting periodic regeneration at the design time point, when the design flow point is used, or when the flow requirements are met at the design time point. During regeneration, time (min) is used as the judgment condition, and the backwashing (min), salt absorption (min), water replenishment (min), and forward washing (min) programs are run. Water replenishment can be done before backwashing or before forward washing without affecting the operation of other stations, as long as water is replenished during the regeneration process.

[0048] In practical applications, the regeneration station includes working condition 1 and working condition 2, and its specific working process is as follows:

[0049] Working condition 1: If Figure 4As shown, after the softening filter material in the resin tank fails to operate, the control program controls the electric control board to start the motor 4 to drive the moving valve plate 16 to rotate. At this time, the moving valve plate 16 is connected with the first regeneration flow channel hole of the fixed valve plate 3, and other stations and other regeneration channels are closed. The raw water enters the first regeneration flow channel in the control valve body 5 from the water inlet 6 of the soft water valve. At this time, the regeneration flow rate is a, and then enters the mixer 15 from the valve body 5. The salt water is sucked from the salt box 12 through the salt valve 11 through the salt absorption pipe 14 to mix into a regeneration liquid with a concentration of A. The regeneration liquid enters the first regeneration flow channel in the valve body 5, and then enters the lower water distributor 10 from the valve body 5 through the center pipe 8. The lower water distributor 10 disperses the regeneration liquid flow and then uniformly contacts the softening filter material 9 from bottom to top for regeneration. The regeneration wastewater is collected by the upper water distributor 13 and then input into the flow channel in the valve body 5, and finally discharged from the wastewater outlet 2 of the softening valve.

[0050] Working condition 2: If Figure 5 As shown, when the salt utilization rate of the regeneration process begins to decrease, the control program controls the electric control board to start the motor 4 to drive the moving valve plate 16 to rotate. At this time, the moving valve plate 16 is connected with the second regeneration flow channel hole of the fixed valve plate 3, and other stations and other regeneration channels are closed. The raw water enters the second regeneration flow channel in the control valve body 5 from the water inlet 6 of the soft water valve. At this time, the regeneration flow rate is b, and then enters the mixer 15 from the valve body 5. The salt water is sucked from the salt box 12 through the salt valve 11 through the salt absorption pipe 14 to mix into a regeneration liquid with a concentration of B. The regeneration liquid enters a regeneration flow channel in the valve body 5, and then enters the lower water distributor 10 from the valve body 5 through the central pipe 8. The lower water distributor 10 disperses the regeneration liquid flow and uniformly contacts the softening filter material 9 from bottom to top. The utilization rate of the regeneration liquid is improved by adjusting the regeneration ion environment. The regeneration wastewater is collected by the upper water distributor 13 and then input into the flow channel in the valve body 5, and finally discharged from the wastewater outlet 2 of the softening valve.

[0051] It should be noted that in the above working conditions 1 and 2, the regeneration flow rate a≠b, the regeneration liquid concentration A≠B, the number of regeneration channels 19 is greater than or equal to 2, and the flow area of ​​each regeneration channel is different. When the utilization rate of the salt solution decreases during the regeneration process, the hardness ion concentration (A is less than B) is reduced by first reducing the concentration of the regeneration liquid and increasing the flow rate (a is greater than b); then the utilization rate of the regeneration liquid is increased by increasing the concentration of the regeneration liquid and reducing the flow rate.

[0052] like Figure 5 As shown, in one of the embodiments, the softening valve of the water softening equipment further includes a valve housing 17 , and the main valve body 5 is built in the valve housing 17 .

[0053] The valve housing 17 is mainly used to isolate and protect the main valve body 5 and the drive assembly and the regeneration flow channel regulating assembly built in the main valve body 5. The valve housing can be made of metal material or high-strength plastic material.

[0054] In order to further illustrate the specific technical principles of the softening valve of the water softening equipment of the present application, the other four workstations of the softening system of the water softening equipment will be described in detail below.

[0055] Softening operation

[0056] like Figure 1 As shown, during the softening operation, the control program controls the electric control board to start the motor 4 to drive the moving valve plate 16 to rotate. At this time, the moving valve plate 16 is connected with the running flow channel hole of the fixed valve plate 3, and other channels are closed. Raw water enters the running flow channel in the main valve body 5 from the water inlet 6 of the soft water valve, and the raw water is dispersed from the main valve body 5 through the upper water distributor 13, and then enters the resin tank 7. After the raw water is filtered and softened by the softening filter material 9 from top to bottom, the softened water is collected by the lower water distributor 10 and then merged into the flow channel in the valve body 5 from the central pipe 8. Finally, the soft water is input into the household water pipe from the water outlet 18 for users to use.

[0057] Backwash

[0058] like Figure 6 As shown, when backwashing is in operation, the control program controls the electric control board to start the motor 4 to drive the moving valve plate 16 to rotate. At this time, the moving valve plate 16 is connected with the backwash flow channel hole of the fixed valve plate 3, and other channels are closed. Raw water enters the backwash flow channel in the control valve body 5 from the water inlet 6 of the soft water valve, and the raw water is input into the lower water distributor 10 from the valve body 5 through the central pipe 8. The lower water distributor 10 disperses the water flow and then impacts the water flow from bottom to top to clean the softening filter material 9. The cleaning waste water is collected by the upper water distributor 13 and then input into the flow channel in the valve body 5, and finally discharged from the waste water outlet 2 of the softening valve.

[0059] Washing

[0060] like Figure 7 As shown, when the positive wash is running, the control program controls the electric control board to start the motor 4 to drive the moving valve plate 16 to rotate. At this time, the moving valve plate 16 is connected with the positive wash flow channel hole of the fixed valve plate 3, and other channels are closed. The raw water enters the positive wash flow channel in the control valve body 5 from the water inlet 6 of the soft water valve, and the raw water disperses the water flow from the valve body 5 through the upper water distributor 13, and then enters the resin tank 7. After the raw water washes the softening filter material 9 from top to bottom, the washing waste water is collected by the lower water distributor 10 and then merged into the flow channel in the valve body 5 from the central pipe 8. Finally, the waste water is discharged from the waste water outlet of the softening valve.

[0061] Hydration

[0062] like Figure 8As shown, after the regeneration completes the flushing and salt absorption process, the softening system begins to add a certain amount of water to the salt box 12 to dissolve the softening salt to form a high-concentration salt solution, in preparation for the next regeneration. At this time, the control program controls the electric control board to start the motor 4 to drive the movable valve plate 16 to rotate. At this time, the movable valve plate 16 is connected with the water replenishment channel hole of the fixed valve plate 3, and other channels are closed. The raw water enters the water replenishment channel in the control valve body 5 from the water inlet 6 of the soft water valve. The raw water disperses the water flow from the valve body 5 through the upper water distributor 13, and then enters the resin tank 7. After the raw water passes through the softening filter material 9 from top to bottom, the softened water is collected by the lower water distributor 10 and then flows into the valve body 5 from the central pipe 8 and then injected into the mixer 15. Finally, the softened water is injected into the salt box 12 from the salt pipe 14 and the salt valve 11 connected to the mixer.

[0063] In addition, the present application also provides a water softening equipment softening system, including a regeneration module, an operation module and the above-mentioned water softening equipment softening valve; the regeneration module is connected to the operation module through the water softening equipment softening valve.

[0064] The softening system of the water softening equipment of the present application includes a regeneration module, an operation module and a softening valve of the water softening equipment. The softening valve of the water softening equipment is provided with regeneration flow channels with different flow areas. The regeneration flow channels are driven by a driving component to drive a regeneration flow channel regulating component to adjust the conductive regeneration flow channels, so as to adjust the flow rate of the regeneration liquid entering the softening filter material through the softening valve of the water softening equipment, thereby realizing the regeneration liquid flow control during the regeneration process, improving the utilization rate of the regeneration liquid and the regeneration recovery degree of the softening filter material, and realizing efficient regeneration.
