Description

Technical Field

[0001] This utility model relates to a water treatment system, and more specifically to a water softening valve and a water treatment system. Background Technology

[0002] Modern industrial and domestic water treatment systems frequently utilize multi-functional control valves, particularly in the field of softened water treatment. Multi-functional softened water valves are widely used to switch water flow channels, enabling functions such as water production, backwashing, brine / slow washing, brine tank replenishment, and forward washing. The applicant's pioneering planar-sealed multi-functional softened water valve, due to its simple structure and high reliability, has become the mainstream control valve for softened water treatment in the market. Existing planar-sealed multi-functional softened water valves typically replenish raw water (i.e., hard water) to the brine tank, and this replenishment is a time-consuming process. Furthermore, softened water valves that simultaneously possess co-current and counter-current regeneration functions suffer from limited softened water flow due to design limitations.

[0003] For example, the utility model patent filed by this applicant in 2020, entitled "An Energy-Saving Multifunctional Softening Valve," with publication number CN216377509U, provides a multi-tank series-connected softening water treatment system. The upper water distribution ports of two adjacent tanks are connected by pipes, allowing water to first enter the softening valve through the upper water distribution port, then pass through the tanks, and finally return to the softening valve through the lower water distribution port. This is similar to the patent... Figure 4 As shown, water first flows from the upper water distribution port on the valve body to the first water distribution channel 38a1, then to the auxiliary tank. It enters through the first port of the auxiliary tank, then flows out through the second port to the second water distribution channel 38a2, entering the second port of the main tank. From the first port of the main tank, it flows back to the softening valve through the lower water distribution port. Currently, all existing softening valves are planar valves, such as those in announcement number CN204083361. As shown in the utility model patent U, entitled "An Energy-Saving Multifunctional Soft Water Valve," the valve plate has six through holes. The first and fourth through holes are interconnected and connected to the lower water distribution interface, while the second through hole is connected to the upper water distribution interface. Due to the equally distributed through holes on the valve plate, the second through hole occupies less space. When used in a multi-tank series connection, the water needs to flow to the auxiliary tank, then to the main tank, and finally back to the valve body. Compared to a single-tank valve, the required flow rate and space at the upper water distribution interface are greater. Thus, the existing valve plate structure suffers from insufficient flow to the auxiliary tank, leading to a decrease in the overall water supply system flow rate. Utility Model Content

[0021] Based on the improved structure of the moving valve plate and the fixed valve plate described above, this utility model further provides the following cooperation relationship: the cooperation relationship between the moving valve plate and the fixed valve plate includes: the water inlet channel of the moving valve plate is connected to the sixth through hole, the conducting channel is connected to the first through hole and the eighth through hole, and the sewage discharge channel is blocked, which is the first working state; or the water inlet channel of the moving valve plate is connected to the sixth through hole, the conducting channel is connected to the first through hole, the eighth through hole and the second through hole, and the sewage discharge channel is blocked, which is the second working state; or the water inlet channel of the moving valve plate is connected to the seventh through hole, the conducting channel is connected to the second through hole and the first through hole, and the sewage discharge channel is connected to the fourth through hole, which is the third working state; or the moving valve plate's...

The softening valve is as described above.

[0023] The beneficial effect of this utility model is that, compared with the existing technology that uses a single through hole on the fixed valve plate to connect with the upper water distribution interface, the fixed valve plate of this utility model is equipped with a fourth through hole, a fifth through hole, and a sixth through hole to connect with the upper water distribution interface. With the fixed valve plate evenly distributed, the upper water distribution interface can connect to a larger flow space on the fixed valve plate. Therefore, in the case of multiple tanks connected in series using valves, it can effectively provide a larger flow to the auxiliary tank, avoiding the problem of insufficient flow to the auxiliary tank, which would lead to a decrease in the overall water supply system flow.

[0055] The following will further elaborate on the present utility model in combination with the embodiments given in the drawings. In the drawings, the word "outer" on the fixed valve plate c indicates connection to the upper water distribution interface 38, the word "inner" indicates connection to the lower water distribution interface 39, the word "suction" indicates connection to the brine suction port 36, the word "waste" indicates connection to the sewage discharge port 33, and the word "inject" indicates connection to the injector water inlet 34.

[0056] Refer to Figure 1 As shown, a softening valve of this embodiment includes:

[0057] A valve body a, on which there are provided a water inlet 31, a water outlet 32, a sewage discharge port 33, an injector water inlet 34, a brine suction port 36, an upper water distribution interface 38 and a lower water distribution interface 39. The water inlet 31 accesses raw water, the water outlet 32 provides water supply, and the upper water distribution interface 38 and the lower water distribution interface 39 are respectively connected to the first interface and the second interface of the softening tank;

[0058] A movable valve plate b, on which there are provided a water inlet channel 21, a conduction channel 22 and a sewage discharge channel 23. The water inlet channel [[ID=[]45]]

[0059] A fixed valve plate c has a first through hole 1, a second through hole 2, an eighth through hole 8, a fourth through hole 4, a fifth through hole 5, a sixth through hole 6, and a seventh through hole 7. The fourth through hole 4, the fifth through hole 5, and the sixth through hole 6 are interconnected and connected to the upper water distribution interface 38. The first through hole 1 is connected to the lower water distribution interface 39. The eighth through hole 8 is connected to the water outlet 32. The second through hole 2 is connected to the brine suction port 36. The seventh through hole 7 is connected to the jet injector inlet 34.

[0060] A drive mechanism is provided on valve body a. This drive mechanism is linked with the moving valve plate b to drive the moving valve plate b to rotate on the fixed valve plate c, thereby changing the cooperation relationship between the moving valve plate b and the fixed valve plate c. The drive mechanism is a valve stem, which can be driven by an actuator or a handwheel, etc. In the process of using the softening valve of this embodiment, it can be used for single-tank and multi-tank situations. In the case of single-tank use, the flow rate to the upper water distribution interface 38 can be increased due to the setting of the fourth through hole 4, the fifth through hole 5 and the sixth through hole 6. In the case of multi-tank use, the softening valve is first installed on the main tank, the central pipe of the main tank is installed at the lower end of the lower water distribution interface 39 of valve body a, and then a pipe is connected to the upper water distribution interface 38 to connect to the auxiliary tank. Figure 1 As shown, two parallel pipes are used to form the first upper water distribution channel 38a1 and the second upper water distribution channel 38a2 for connection. By using the fourth through hole 4, the fifth through hole 5 and the sixth through hole 6, the installation space for two parallel pipes can be provided on one plane. Compared with the single hole solution in the prior art, this is better suited for multi-tank series connection.

[0061] Based on the above-mentioned basic structure, this utility model provides the following embodiments:

[0062] Example 1

[0063] Reference Figures 2 to 3 As shown, based on the above basic structure, this embodiment provides an 8.5-part division embodiment. The fixed valve plate c is also provided with a third through hole 3, which communicates with the fourth through hole 4, the fifth through hole 5, and the sixth through hole 6. The diameter of the third through hole 3 is smaller than the diameters of the fourth through hole 4, the fifth through hole 5, and the sixth through hole 6. The fourth through hole 4, the fifth through hole 5, and the sixth through hole 6 are all arranged on one side of the fixed valve plate c. The first through hole 1 and the eighth through hole 8 are arranged on the side of the fixed valve plate c that is symmetrical to the center of the fourth through hole 4, the fifth through hole 5, and the sixth through hole 6, as shown. Figure 3As shown, by positioning the third through hole 3, the fourth through hole 4, the fifth through hole 5, and the sixth through hole 6 on either the left or right side of the fixed valve plate c, the inlet 31 and the outlet 32 ​​can be installed on either the right or left side of the valve body a. This ensures a sufficiently large flow rate while also providing enough space for the first upper water distribution channel 38a1 and the second upper water distribution channel 38a2 to be connected and installed. Furthermore, the flow channels on the valve body a are simpler and easier to manufacture. The second through hole 2 is positioned between the third through hole 3 and the first through hole 1. The seventh through hole 7 is positioned between the sixth through hole 6 and the eighth through hole 8. The fixed valve plate c also has a ninth through hole 9, which is located at the center of the fixed valve plate c. In the case of an 8.5-division system, the "outer" portion of the third through hole 3, the fourth through hole 4, the fifth through hole 5, and the sixth through hole 6 occupies between 3 and 4 equal divisions of the entire 8.5-division system, i.e., 127.06 degrees to 169.41 degrees.

[0064] Based on the fixed valve plate structure of Embodiment 1, the following cooperation relationship exists between the fixed valve plate c and the moving valve plate b, as described below. Figures 4 to 15 As shown, the first working state is characterized by the following: the water inlet channel 21 of the moving valve plate b is connected to the fifth through hole 5 and the sixth through hole 6; the conducting channel 22 is connected to the first through hole 1 and the eighth through hole 8; and the sewage discharge channel 23 is blocked. Alternatively, the second working state is characterized by the water inlet channel 21 of the moving valve plate b being connected to the sixth through hole 6; the conducting channel 22 being connected to the first through hole 1, the eighth through hole 8, and the second through hole 2; and the sewage discharge channel 23 being blocked. Alternatively, the third working state is characterized by the water inlet channel 21 of the moving valve plate b being connected to the seventh through hole 7; the conducting channel 22 being connected to the second through hole 2 and the first through hole 1; and the sewage discharge channel 23 being connected to the third through hole 3 and the fourth through hole 4. In the first working state, the inlet channel 21 of the moving valve plate b is connected to the first through hole 1, the guiding channel 22 is connected to the fourth through hole 4 and the fifth through hole 5, and the drain channel 23 is connected to the sixth through hole 6. Alternatively, the inlet channel 21 and the drain channel 23 of the moving valve plate b are not connected, and the guiding channel 22 is connected to the fifth through hole 5, the sixth through hole 6, and the seventh through hole 7. In the second working state, the inlet channel 21 of the moving valve plate b is connected to the fourth through hole 4 and the fifth through hole 5, the guiding channel 22 is connected to the eighth through hole 8, and the drain channel 23 is connected to the first through hole 1. In the third working state, if... Figure 4 and Figure 5 As shown, in the softened water output state, raw water enters from the inlet channel 21, then enters the fifth through hole 5 and the sixth through hole 6, and then enters the softening tank for softening through the upper water distribution interface 38. The softened water then enters the guiding channel 22 through the first through hole 1, and then enters the eighth through hole 8 through the guiding channel 22. Finally, it enters the outlet 32 ​​of the valve body through the eighth through hole 8, thus supplying soft water. At this time, no water flows through the drain channel 23. In the aforementioned second working state, as... Figure 6 and Figure 7As shown, in the working state of simultaneously softening water and replenishing the brine tank, raw water enters from the inlet channel 21, then enters the softening tank through the sixth through-hole 6 for softening. The softened water then enters the guiding channel 22 through the first through-hole 1, and then enters the eighth through-hole 8 and the second through-hole 2 through the guiding channel 22. While providing softened water to the outlet 32, it also replenishes the brine tank with softened water through the second through-hole 2. In the aforementioned third working state, as... Figure 8 and Figure 9 As shown, in the reverse suction working state, raw water enters from the inlet channel 21, then enters the ejector through the seventh through hole 7. The ejector causes the second through hole 2 to draw brine from the brine tank, which is then sent through the guide channel 22 to the first through hole 1. From the first through hole 1, it enters the softening tank for regeneration. Afterwards, wastewater enters the drain channel 23 through the third through hole 3 and the fourth through hole 4, and is discharged through the drain channel 23. In the aforementioned fourth working state, as... Figure 10 and Figure 11 As shown, this is the backwashing operation state. Raw water enters through the inlet channel 21, passes through the first through-hole 1 into the softening tank, and cleans the softening tank. Afterwards, wastewater is transported through the sixth through-hole 6 to the drain channel 23 for discharge. In the aforementioned fifth operating state, as... Figure 12 and Figure 13 As shown, in the vacation working state, the water inlet channel 21 is closed through the blank area on the fixed valve plate c, the conduction channel 22 connects the fifth through hole 5, the sixth through hole 6, and the seventh through hole 7, and the drainage channel 23 is closed through the blank area on the fixed valve plate c. At this time, there is no water flow in the entire control valve, and it can remain inactive for a long time. Compared with the prior art, when closed, because the conduction channel 22 connects the seventh through hole 7 and the eighth through hole 8, it is easy for water at the outlet 32 ​​to flow back into the brine tank, causing potential hazards. In the above sixth working state, as... Figure 14 and Figure 15 As shown, this is the forward washing working state. Raw water enters from the inlet channel 21, enters the fourth through hole 4 and the fifth through hole 5, and then cleans the softening tank. After that, the sewage enters from the first through hole 1 into the drain channel 23 and is discharged through the drain channel 23. The connecting channel 22 is connected to the eighth through hole 8, but it is not connected to other through holes, so no water flows through it. In this way, by means of the through hole arrangement of the fixed valve plate c, each working state can be switched one by one by rotating counterclockwise.

[0065] Based on the method of Embodiment 1 above, this embodiment also provides a technical solution in which the drain outlet is located on the shift fork, referring to... Figures 16 to 17 As shown, the ninth through hole 9 at the center of the fixed valve plate c is removed, and the sewage discharge channel 23 is connected to the outside via the shift fork. The cooperation relationship between the remaining moving valve plate b and the fixed valve plate c is the same as described above. Figures 18 to 19 The backwashing status is provided, so it will not be described in detail here.

[0066] Based on the approach described in Embodiment 1 above, this embodiment also provides a corresponding mirror structure, such as... Figures 20 to 21 As shown, this is a mirror image of a valve plate c with a ninth through hole 9 at its center. Figures 22 to 23 The image shown is a mirror image of the situation where the ninth through hole 9 at the center of the fixed valve plate c is removed.

[0067] In Example 1, the outer edge of the eighth through hole 8 of the fixed valve plate c extends to a bypass hole 100. Through the bypass hole 100, a corresponding additional part is provided on the moving valve plate c. The bypass hole 100 is covered by the additional part, which, depending on whether it completely covers the bypass hole 100, ensures that in the first, second, and fifth working states, the outer edge of the passive valve plate b (i.e., the additional part) of the bypass hole 100 is closed. In other working states, it is not covered. Therefore, in the soft water production working state, the brine tank soft water replenishment working state, and the vacation working state, the outlet 32 ​​does not discharge raw water; in other working states, the outlet 32 ​​discharges raw water for user use. Accordingly, this embodiment provides a structure without a hard water bypass, as described in Example 1. Figures 24 to 25 As shown, the corresponding coordination relationship is the same as that of the above-mentioned cases with hard water bypass, so it will not be repeated here. Figures 26 to 34 As shown, there is also a solution where the drain outlet is on the shift fork, such as... Figures 35 to 36 As shown, the corresponding method is also through Figures 37 to 38 It provides the backwashing operation status, and Figures 39 to 42 It also provides a corresponding mirror structure.

[0068] Example 2

[0069] Reference Figures 43 to 44 As shown, based on the above basic structure, this embodiment provides a 9-part division embodiment. The fixed valve plate c is also provided with a third through hole 3, which communicates with the first through hole 1. The fourth through hole 4, the fifth through hole 5, and the sixth through hole 6 are all arranged on one side of the fixed valve plate c. The first through hole 1 and the third through hole 3 are arranged on the side of the fixed valve plate c that is symmetrical to the center of the fourth through hole 4, the fifth through hole 5, and the sixth through hole 6, as shown. Figure 44As shown, by positioning the fourth through hole 4, the fifth through hole 5, and the sixth through hole 6 on either the left or right side of the fixed valve plate c, the right side of the valve body a can accommodate the installation of the inlet 31 and the outlet 32. This ensures a sufficiently large flow rate while also providing enough space within the valve body for connecting and installing the first upper water distribution channel 38a1 and the second upper water distribution channel 38a2. The second through hole 2 and the seventh through hole 7 are adjacent to each other and located between the third through hole 3 and the fourth through hole 4. The eighth through hole 8 is located between the sixth through hole 6 and the first through hole. Between 1, the fixed valve plate c is also provided with a closed blind hole 1A, which is located between the third through hole 3 and the first through hole 1. Compared with the above 8.5 division, the 9 division adopts the second through hole 2 and the seventh through hole 7 adjacent to each other between the third through hole 3 and the fourth through hole 4, and at the same time, an additional third through hole 3 connected to the first through hole 1 is provided. In the case of 9 division, the "outside" of the fourth through hole 4, the fifth through hole 5 and the sixth through hole 6 occupies 3 parts of the entire 9 division of the circumference, that is, 120 degrees.

[0070] Therefore, based on the above-mentioned structure of the fixed valve plate c, the moving valve plate b and the fixed valve plate c, which are divided into 9 equal parts, have the following matching relationship: (Refer to...) Figures 45 to 50As shown, the first working state is characterized by the following configurations: The inlet channel 21 of the moving valve plate b is connected to the sixth through hole 6; the conducting channel 22 is connected to the first through hole 1 and the eighth through hole 8; and the drain channel 23 is connected to the second through hole 2. Alternatively, the second working state is characterized by the inlet channel 21 of the moving valve plate b being connected to the first through hole 1; the conducting channel 22 being connected to the third through hole 3; and the drain channel 23 being connected to the fifth through hole 5. The third working state is characterized by the following configurations: The inlet channel 21 of the moving valve plate b is not connected; the conducting channel 22 is connected to the third through hole 3 and the seventh through hole 7; and the drain channel 23 is connected to the sixth through hole 6. The fourth working state is characterized by the following configurations: The inlet channel 21 of the moving valve plate b is connected to the seventh through hole 7; the conducting channel 22 is connected to the fourth through hole 4 and the second through hole 2; and the drain channel 23 is connected to the first through hole 1. In the first working state, the inlet channel 21 of the actuated valve plate b is connected to the second through hole 2, the conduction channel 22 is connected to the fourth through hole 4 and the fifth through hole 5, and the drain channel 23 is blocked, which is the fifth working state. In the second working state, the inlet channel 21 of the actuated valve plate b is connected to the fourth through hole 4, the conduction channel 22 is connected to the fifth through hole 5 and the sixth through hole 6, and the drain channel 23 is connected to the third through hole 3, which is the sixth working state. The above-mentioned first working state is the operation state of softening water production. Raw water enters from the inlet channel 21, enters the external softening tank through the sixth through hole 6, and then the softened water enters the first through hole 1 through the conduction channel 22 into the eighth through hole 8, and the softened water exits through the eighth through hole 8. The drain channel 23 is connected to the second through hole 2 and is empty. In the second working state, which is the backwashing state, raw water enters from the inlet channel 21 and flows into the softening tank through the first through hole 1. After cleaning the softening tank, the wastewater enters the drain channel 23 through the fifth through hole 5. The third through hole 3 is connected to the closed blind hole 1A through the guide channel 22. In the third working state, which is the backwashing state, raw water enters from the inlet channel 21 and is closed by the closed blind hole 1A. The drain channel 23 is connected to the sixth through hole 6. The seventh through hole 7 and the third through hole 3 are connected through the guide channel 22, but no water flows through them. At the same time, the eighth through hole 8 is closed, so there will be no backflow of water from the outlet 32 ​​into the brine tank. In the fourth working state, which is the forward suction state, raw water enters from the inlet channel 21. 1. The brine enters through the seventh through-hole 7 and is jetted. Then, the brine flows from the second through-hole 2 into the guiding channel 22, and then from the fourth through-hole 4 into the softening tank. After the softening tank is regenerated, the wastewater flows from the first through-hole 1 into the drain channel 23. The fifth working state is the raw water replenishment state. Raw water enters from the inlet channel 21, passes through the second through-hole 2, and enters the brine tank to replenish the brine tank. At this time, the guiding channel 22 is closed by connecting the fourth through-hole 4 and the fifth through-hole 5, and the drain channel 23 is closed by connecting the closed blind hole 1A. The sixth working state is the forward washing state. Raw water enters from the inlet channel 21, then passes through the fourth through-hole 4 into the softening tank. After cleaning the softening tank, the wastewater returns from the third through-hole 3 and then enters the drain channel 23.At this point, the connecting channel 22, which connects the fifth through hole 5 and the sixth through hole 6, is closed, and there is no water flow.

[0071] Based on the method of Embodiment 2 above, this embodiment also provides a technical solution in which the drain outlet is located on the shift fork, referring to... Figures 51 to 52 As shown, the ninth through hole 9 at the center of the fixed valve plate c is cancelled, and the sewage discharge channel 23 is selected to connect to the outside with the shift fork. The cooperation relationship between the remaining moving valve plate b and the fixed valve plate c is the same as in the above embodiment 2, so it will not be described again.

[0072] Based on the method of Embodiment 2 above, this embodiment also provides a corresponding mirror structure, such as... Figures 53 to 54 As shown, this is a mirror image of a valve plate c with a ninth through hole 9 at its center. Figures 55 to 56 The image shown is a mirror image of the situation where the ninth through hole 9 at the center of the fixed valve plate c is removed.

[0073] Referring to the 8.5 division method in Example 1, the eighth through hole 8 in Example 2 also extends with a through hole 100. Through the function of the through hole 100, the water outlet can supply raw water to users when not in the soft water production working state or in the vacation working state.

[0074] Based on the hard water bypass described in Example 2, referring to... Figures 57 to 70 This embodiment also provides a method without the through hole 100.

[0075] Example 3

[0076] Reference Figures 71 to 72 As shown, based on the above basic structure, this embodiment provides a 7-division version. The 7-division structure is the same as the basic structure, and similarly, as... Figure 72 As shown, with the valve body divided into 7 equal parts, the fourth through hole 4, the fifth through hole 5, and the sixth through hole 6 are all located on the left or right side of the fixed valve plate c, allowing the inlet 31 and outlet 32 ​​to be installed on the right or left side of the valve body a. This ensures a sufficiently large flow rate while also providing enough space for the first upper water distribution channel 38a1 and the second upper water distribution channel 38a2 to be connected and installed. With the valve body divided into 7 equal parts, the "outer" portion of the fourth through hole 4, the fifth through hole 5, and the sixth through hole 6 occupies between 2 and 3 of the 7 equal parts of the circumference, i.e., 102.86 degrees to 154.29 degrees. Figures 73 to 80As shown, the moving valve plate b and the fixed valve plate c have the following matching relationships: The first working state is characterized by the moving valve plate b having its inlet channel 21 connected to the sixth through hole 6, its conducting channel 22 connected to the first through hole 1 and the eighth through hole 8, and its drain channel 23 blocked. Alternatively, the second working state is characterized by the moving valve plate b having its inlet channel 21 connected to the sixth through hole 6, its conducting channel 22 connected to the first through hole 1, the eighth through hole 8, and the second through hole 2, and its drain channel 23 blocked. The third working state is characterized by the moving valve plate b having its inlet channel 21 connected to the seventh through hole 7, its conducting channel 22 connected to the second through hole 2 and the first through hole 1, and its drain channel 23 connected to the fourth through hole 4. The fourth working state is characterized by the moving valve plate b having its inlet channel 21 connected to the first through hole 1, its conducting channel 22 connected to the fourth through hole 4 and the fifth through hole 5. The sewage discharge channel 23 is connected to the sixth through hole 6 in the fourth working state; or the water inlet channel 21 of the moving valve plate b is not blocked, and the sewage discharge channel 23 is connected to the eighth through hole 8. The guiding channel 22 is connected to the fifth through hole 5 and the sixth through hole 6 in the fifth working state; or the water inlet channel 21 of the moving valve plate b is connected to the fifth through hole 5, the guiding channel 22 is connected to the eighth through hole 8 and the seventh through hole 7, and the sewage discharge channel 23 is connected to the first through hole 1 in the sixth working state. The first working state is the water softening working state. Raw water enters from the water inlet channel 21, enters the softening tank through the sixth through hole 6, and the softened water returns through the first through hole 1. Then it enters the eighth through hole 8 through the guiding channel 22, and soft water is discharged from the outlet 32. At the same time, there is no water flow in the sewage discharge channel 23. In the second working state... In the first working state, which simultaneously softens the water and replenishes the brine tank, raw water enters through the inlet channel 21, then enters the softening tank through the sixth through-hole 6 for softening. The softened water then enters the guiding channel 22 through the first through-hole 1, and then through the guiding channel 22 to the eighth through-hole 8 and the second through-hole 2. While providing softened water to the outlet 32, it also replenishes the brine tank with softened water through the second through-hole 2. In the third working state, which is a reverse suction state, raw water enters through the inlet channel 21, then enters the ejector through the seventh through-hole 7. The ejector causes the second through-hole 2 to draw brine from the brine tank, and then sends it through the guiding channel 22 to the first through-hole 1. From the first through-hole 1, it enters the softening tank for regeneration. Afterwards, wastewater flows through... The wastewater enters through the fourth through-hole 4 and enters the sewage discharge channel 23, where it is discharged. In the fourth working state, which is the backwashing state, the raw water enters through the inlet channel 21, passes through the first through-hole 1, and enters the softening tank to clean it. Afterward, the wastewater returns through the fourth through-hole 4 and the fifth through-hole 5 into the guiding channel 22, and is transported through the sixth through-hole 6 to the sewage discharge channel 23 for discharge. In the fifth working state, which is the vacation state, the inlet channel 21 is closed by the blank area on the fixed valve plate c, the guiding channel 22 is open to the fourth through-hole 5 and the sixth through-hole 6, and the drainage channel 23 is connected to the eighth through-hole 8. At this time, there is no water flow in the entire control valve, and it can remain idle for a long time. The water flowing back from the outlet 32 ​​can be discharged through the sewage discharge channel 23.Compared to existing technologies where, when shut down, the connecting channel 22 connects to the seventh and eighth through holes 7 and 8, potentially causing water to flow back into the brine tank from the outlet 32 ​​and creating a safety hazard, the sixth operating state described above is a forward washing state. Raw water enters through the inlet channel 21, flows into the fifth through hole 5, and then cleans the softening tank. Afterward, wastewater enters through the first through hole 1 and flows into the drain channel 23, where it is discharged. The connecting channel 22 connects to the eighth and seventh through holes 8 and 7, but does not connect to other through holes, therefore no water flows through it.

[0077] Based on the hard water bypass described in Example 3, and referring to... Figures 81 to 90 This embodiment also provides a method without the through hole 100.

[0078] Example 4

[0079] Reference Figures 91 to 108 As shown, based on the above basic structure, this embodiment provides a 7.5-division embodiment. The 7.5-division structure is the same as the basic structure, and the fit relationship is basically the same as the 7-division, so it will not be described again. The difference between it and the 7-division is that the diameter of the fourth through hole 4 is slightly different, and the positions of the second through hole 2 and the seventh through hole 7 are slightly different. Therefore, in the case of 7.5 division, the "outer" part of the fourth through hole 4, the fifth through hole 5 and the sixth through hole 6 occupies 3 parts of the entire 7.5 division, that is, 144 degrees.

[0080] In the existing technology, when the single through hole of the fixed valve plate is considered "outer", the maximum angle that it can reach is between 2 and 3 of the 10 equal parts of the entire circumference, that is, 72 degrees to 108 degrees, which is significantly smaller than the four embodiments mentioned above. Therefore, the four embodiments mentioned above have better advantages in the valve working conditions of multiple tanks in series.

[0081] In summary, the softening valve of this embodiment, through the setting of the fourth through hole 4, the fifth through hole 5 and the sixth through hole 6, can more easily connect the auxiliary tanks in series when multiple tanks are used in series.

[0082] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. 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.
