Description

Technical Field

[0001] The utility model relates to a water softener, and in particular to a water softener capable of softening raw water (or tap water) to obtain softened water. The utility model further relates to a control valve for the water softener, which can control a larger flow of raw water to be provided to a softening device of the water softener when the control valve is in a softening working position, so that a larger flow of raw water is softened. Background Art

[0002] With the increasing improvement of people's living standards and the increasing attention to health, people have higher and higher requirements for the quality of domestic water. However, in many countries, especially in developing countries, many tap water sources are groundwater or surface water with high hardness, which are provided to users after purification and disinfection. Tap water with high hardness can easily damage the protective layer of the skin, causing dry skin and even skin allergies for users. In addition, tap water with high hardness may also affect the cleaning effect of skin cleansing products and the beauty effect of cosmetics. Therefore, when using tap water with high hardness to wash the face, the user's experience is poor. Water with lower hardness, such as softened water obtained by softening tap water, is less irritating and gentler to the user's skin, and is more suitable for people to use when bathing, cleaning the skin and applying makeup. For example, it can be used when cleaning the face.

[0003] Many existing water softeners use multiple control valves to control the multi-directional flow of water, so that the water softener needs to realize multiple functions such as water softening, regeneration of softening materials, water replenishment, etc. When realizing the corresponding functions, the water softener using multiple control valves has a complex structure, high manufacturing cost, large volume, and brings inconvenience to automatic control. In order to reduce the number of control valves of the water softener and reduce the complexity and difficulty of realizing the functions of the water softener, people have further developed a variety of planar control valves to reduce the number of control valves of the water softener and reduce the difficulty of automatic control of the complex functions of the water softener.

[0004] The Chinese invention patent with application number CN200820169873.5 discloses a multifunctional softening valve, which includes a valve body, a valve core and an ejector. The valve body is provided with a plurality of openings for water to flow in or out, the valve core is used to control the flow direction of the water flow, and the ejector is used to allow saline to flow from the saline container into the softening tank to elute softening materials such as resin and allow water from the water inlet of the valve body to enter the saline container to replenish the water in the saline container. As shown in Figure 8 of the accompanying drawings, when the multifunctional softening valve provided by the patent controls the water softener to soften raw water, the raw water flows from the through hole 25 into the through hole 19, and then flows to the softening tank. After the softening material in the softening tank is softened, the obtained softened water flows to the soft water outlet through the through hole 24, the blind hole 28 and the through hole 18. Accordingly, when the multifunctional softening valve provided by the patent controls the water softener to soften raw water, the water flow rate is determined by the area of ​​the through hole 25, the area of ​​the through hole 19, the area of ​​the through hole 24, the area of ​​the blind hole 28 and the area of ​​the through hole 18 in the overlapped part of the movable valve plate 4 and the fixed valve plate 5. However, the structure of the multifunctional softening valve provided by the patent is too complicated, the number of through holes is large, the shape is irregular, and the blind holes 28 of the through holes are distributed on the second and third layers (or the second and third circles) from the inside to the outside of the fluid control surface, and the through holes 18 are distributed on the third layer (or the third circle). The third layer is only used by the through holes 18, and the other parts of the third layer are not involved in the water circulation. Although some through holes, such as through holes 19 and through holes 18, occupy a large area in design (occupying two equal parts of the fluid control surface, and the fluid control surface of the entire movable valve plate 4 and the fixed valve plate 5 is designed to be divided into 9 equal parts), when the water softener softens the raw water, the area that actually participates in the conduction is small. The overlapping area of ​​the moving valve plate 4 and the fixed valve plate 5 is only divided into one equal part, which results in that the area of ​​the through hole 19, through hole 24, and through hole 18 (the opening formed on the flow control surface of the fixed valve plate) distributed on the fixed valve plate during the water softening period, especially the area of ​​the overlapping part of the through hole 25 and the through hole 19 that determines the flow rate of the outflow, the area of ​​the overlapping part of the blind hole 28 and the through hole 24, and the area of ​​the overlapping part of the blind hole 28 and the through hole 18 (the opening formed on the flow control surface of the fixed valve plate), accounts for too low a total area of ​​the flow control surface of the entire fixed valve plate, which greatly affects the water flow rate of the water softener when softening the raw water. In order to make the water flow rate through the multifunctional softening valve meet the requirements, the volume of the multifunctional softening valve has to be increased, resulting in its large size and inconvenience in use. The large volume requires a thicker valve body wall thickness to ensure the stability of the valve body under water pressure, which directly leads to an increase in production costs. In addition, no matter whether the movable valve plate of the multifunctional softening valve is made of metal material or ceramic material, if its size is too large, the yield rate will be reduced during its manufacture. In particular, when the movable valve plate of the multifunctional softening valve is made of ceramic material, the larger its size, the easier it is to crack, and the service life is significantly reduced.In addition, in order to achieve continuous supply of raw water in the regeneration or flushing working position, the multifunctional softening valve provided by the patent sets the through hole 18 of the fixed valve plate in the outer circle (or the third circle), resulting in a further reduction in the effective water-passing area of ​​the entire fixed valve plate.

[0005] Therefore, the distribution of the conducting holes of the existing planar control valves for water softeners with continuous water supply functions (supplying soft water during water softening, supplying raw water while regenerating softening materials, supplying raw water while flushing softening materials, and supplying raw water while replenishing water in the brine tank) on the fixed valve plate is double-circle or multi-circle, which leads to low utilization of the flow control surface of the existing planar control valve and small flow rate, so that it has to be designed and manufactured with a larger volume. The large volume of the planar control valve not only leads to a lower yield rate and high cost when it is manufactured, but also reduces the service life of the planar control valve. In addition, the large-volume planar control valve will further increase the volume of the water softener, causing it to occupy a larger indoor space, especially unsuitable for the installation of the kitchen water softener.

[0007] Another advantage of the utility model is that it provides a water softener, wherein the control valve of the water softener of the utility model can not only control the continuous water supply of the water softener, but also overcome the design bias of the existing planar control valve with continuous water supply, so that the conducting through holes participating in the softened water supply and the raw water supply arranged on the water flow control surface of the fixed valve plate are distributed in a single circle, thereby allowing the control valve of the water softener of the utility model to significantly improve the utilization rate of the water flow control surface of the fixed valve plate.

[0008] Another advantage of the utility model is that it provides a water softener, wherein the control valve of the water softener of the utility model is further configured to significantly increase the proportion of the cross-sectional area of ​​the channel for raw water inflow and softened water outflow (the area of ​​the opening on the flow control surface of the fixed valve plate) to the total flow control surface area of ​​the fixed valve plate when controlling the softening of raw water.

[0009] Another advantage of the utility model is that it provides a water softener, in which the control valve of the water softener of the utility model forms two parallel soft water supply passages, so that when the water softener softens raw water, the total cross-sectional area of ​​the inlet channel for supplying raw water to the softening device of the water softener and the total cross-sectional area of ​​the outflow channel for the obtained softened water both become larger as a proportion of the total flow control surface area of ​​the fixed valve plate.

[0010] Another advantage of the utility model is to provide a water softener, wherein the water softener of the utility model is configured to automatically add a regeneration solution, such as a saline solution (sodium chloride solution), into the interior thereof under the driving action of water flow, so that the water softener of the utility model, more specifically, its softening material can be better regenerated to increase the service life of the water softener.

[0011] Another advantage of the utility model is to provide a control valve for a water softener, which can provide a relatively larger channel (an opening formed on the flow control surface of the fixed valve plate) for raw water to flow in and softened water to flow out when controlling raw water to be softened. In particular, the conductive through holes participating in the supply of softened water and raw water on the water flow control surface of the fixed valve plate of the control valve for a water softener of the utility model are distributed in a single circle, thereby further significantly improving the utilization rate of the water flow control surface of the fixed valve plate.

[0206] As shown in the attached picture Figure 3AAs shown, when the water softener according to the first embodiment of the utility model is subjected to downstream regeneration treatment, under the control of the control valve 10, the regeneration solution, such as a salt solution (sodium chloride solution), flows to the first connecting opening 201 of the softening device 20 of the water softener of the utility model, and the regeneration solution flows through the first connecting opening 201, the softening material 23, the second end 222, the first end 221 and the second connecting opening 202 in sequence, and in this process, the softening material 23 of the water softener of the utility model is subjected to downstream regeneration treatment. The waste liquid generated during the downstream regeneration process of the softening material 23 of the water softener of the utility model is discharged from the second connecting opening 202. The downstream regeneration of the utility model means that when the softening device 20 is subjected to regeneration treatment, the flow direction of the regeneration solution in the softening device 20 is substantially the same as the flow direction of the water flow in the softening device 20 when the softening device 20 is subjected to softening treatment on raw water.

[0207] As shown in the attached picture Figure 3B As shown, when the water softener according to the first embodiment of the utility model is subjected to countercurrent regeneration treatment, under the control of the control valve 10, the regeneration solution, such as a salt solution (sodium chloride solution), flows to the second connecting opening 202 of the softening device 20 of the water softener of the utility model, and the regeneration solution flows through the second connecting opening 202, the first end 221, the second end 222, the softening material 23 and the first connecting opening 201 in sequence, and in this process, the softening material 23 of the water softener of the utility model is subjected to countercurrent regeneration treatment. The waste liquid generated during the countercurrent regeneration process of the softening material 23 of the water softener of the utility model is discharged from the first connecting opening 201. The countercurrent regeneration of the utility model means that when the softening device 20 is subjected to regeneration treatment, the flow direction of the regeneration solution in the softening device 20 is substantially opposite to the flow direction of the water flow in the softening device 20 when the softening device 20 is subjected to softening treatment on raw water.

[0208] As shown in the attached picture Figures 2 to 6I As shown, the control valve 10 of the water softener according to the first embodiment of the utility model includes a valve body 11 and a valve core 12, wherein the valve body 11 forms a valve cavity 110, a first opening 1101, a second opening 1102, a first jet opening 1111, a second jet opening 1112, a water outlet 1104, a water inlet 1106 and a sewage opening 1113, wherein the valve core 12 is arranged in the valve cavity 110, wherein the first opening 1101 of the valve body 11 is suitable for being connected to the first connecting opening 201 of the softening device 20, the second opening 1102 of the valve body 11 is suitable for being connected to the second connecting opening 202 of the softening device 20, and the water inlet 1106 of the valve body 11 is suitable for being connected to a raw water source (for example, a tap water pipe).

[0209] As shown in the attached picture Figures 4 to 6IAs shown, the control valve 10 of the water softener according to the first embodiment of the utility model further has an ejector 18, wherein the ejector 18 has an ejection port 182 suitable for being connected to the first ejection opening 1111 of the valve body 11, an ejection port 183 suitable for being connected to the second ejection opening 1112 of the valve body 11, and a salt absorption port 181 respectively connected to the ejection port 182 and the ejection port 183. When water flow, such as tap water flow, flows from the ejection port 182 of the ejector 18 to the ejection port 183 of the ejector 18, negative pressure occurs at the salt absorption port 181 of the ejector 18, so that the regeneration solution can flow from the salt absorption port 181 of the ejector 18 to the ejection port 183 of the ejector 18. Correspondingly, the salt absorption port 181 of the ejector 18 is communicated with the ejection port 182 and the ejection port 183 of the ejector 18 respectively.

[0210] As shown in the attached picture Figure 1 and Figure 2 As shown, the water softener according to the first embodiment of the utility model further includes a salt absorption pipe 184 and a salt solution tank 31, wherein one end of the salt absorption pipe 184 is connected to the salt absorption port 181, and the other end of the salt absorption pipe 184 is connected to the salt solution tank 31, so that the salt solution can be provided to the salt absorption port 181 through the salt absorption pipe 184 or the water flow can flow from the salt absorption port 181 and flow through the salt absorption pipe 184 to the salt solution tank 31 to replenish the salt solution tank 31.

[0211] As shown in the attached picture FIG. 11A to FIG. 11C and Fig. 12AAs shown, the control valve 10 of the water softener according to the first embodiment of the utility model has a softening working position, wherein when the control valve 10 is in the softening working position, the valve core 12 of the control valve 10 forms a first softening flow channel 10011, a second softening flow channel 10012 and a third softening flow channel 10013, wherein the first softening flow channel 10011 is respectively connected to the water inlet 1106 and the first opening 1101 of the valve body 11, the second softening flow channel 10012 is respectively connected to the second opening 1102 and the water outlet 1104, and the third softening flow channel 10013 is respectively connected to the second opening 1102 and the water outlet 1104. Correspondingly, when the control valve 10 is in the softening working position, the raw water flows in from the water inlet 1106 of the valve body 11 of the control valve 10 under the action of water pressure, flows to the first opening 1101 of the valve body 11 through the first softening flow channel 10011, and further flows into the softening device 20 from the first connecting opening 201 of the softening device 20. The softened water after softening treatment by the softening device 20 flows out from the second connecting opening 202 of the softening device 20 and further flows into the second opening 1102. Since the second opening 1102 and the water outlet 1104 are respectively connected through the second softening flow channel 10012 and the third softening flow channel 10013, the softened water flowing into the second opening 1102 flows to the water outlet 1104 and is provided through the second softening flow channel 10012 and the third softening flow channel 10013 respectively. It can be understood that when the control valve 10 of the water softener according to the first embodiment of the utility model is controlled to be in the softening working position, the water softener of the utility model is controlled to be in its softening working state.

[0212] It is worth noting that most of the existing control valves for water softeners, or even all existing control valves for water softeners, use a single softening flow channel for softened water outflow and supply. Under the same volume, the single softening flow channel limits the flow of the control valve, and the size of the softened water outflow further limits the speed of the entire water softener to soften raw water. The control valve 10 of the water softener of the utility model increases the cross-sectional area of ​​the raw water supply flow channel (first softening flow channel 10011) while increasing the softening speed of the entire water softener by adding a softening flow channel to increase the outflow flow of soft water.

[0213] As shown in the attached picture FIG. 11D to FIG. 11F and Fig. 12BAs shown, the control valve 10 of the water softener according to the first embodiment of the utility model has a regeneration working position, wherein when the control valve 10 is in the regeneration working position, the valve core 12 of the control valve 10 forms a first regeneration flow channel 10021, a second regeneration flow channel 10022 and a third regeneration flow channel 10023, wherein the first regeneration flow channel 10021 is respectively connected to the water inlet 1106 and the first jet opening 1111 of the valve body 11, the second regeneration flow channel 10022 is respectively connected to the second opening 1102 and the second jet opening 1112, and the third regeneration flow channel 10023 is respectively connected to the first opening 1101 and the sewage opening 1113. Correspondingly, when the control valve 10 is in the regeneration working position, the raw water flows in from the water inlet 1106 of the valve body 11 of the control valve 10 under the action of water pressure, flows through the first regeneration flow channel 10021 to the first jet opening 1111 of the valve body 11, and then flows into the ejection port 182 of the ejector 18, passes through the ejector 18, and is mixed with the salt solution (such as sodium chloride solution) from the salt absorption port 181 to form a regeneration solution, and the regeneration solution flows into the second ejection port 183 of the ejector 18 into the second ejection port 182 of the valve body 11. The jet opening 1112, then flows into the second opening 1102 of the valve body 11 through the second regeneration flow channel 10022, and the regeneration solution flows into the softening device 20 from the second communication opening 202 of the softening device 20, countercurrently regenerates the water treatment material or mechanism of the softening device 20, such as the softening resin, and the waste water generated after regeneration flows out from the first communication opening 201 of the softening device 20, and then flows out through the first opening 1101 of the valve body 11, the third regeneration flow channel 10023 and the sewage opening 1113 in sequence. It can be understood that when the control valve 10 of the water softener according to the first embodiment of the utility model is controlled to be in the regeneration working position, the water softener of the utility model is controlled to be in its regeneration working state. It is worth noting that the waste water generated after regeneration flows out from the sewage opening 1113. In addition, when the control valve 10 is in the regeneration working position, the valve core 12 of the control valve 10 further forms a first raw water supply channel 10001, wherein the first raw water supply channel 10001 is respectively connected with the water inlet 1106 and the water outlet 1104 of the valve body 11, so that when the control valve 10 is in the regeneration working position, raw water can flow in from the water inlet 1106 of the valve body 11 of the control valve 10 under the action of water pressure, and flow to the water outlet 1104 through the first raw water supply channel 10001, so as to supply raw water when the water softener of the utility model is controlled to be in its regeneration working state.

That is to say, the water flow of the water inlet 1106 is parallelly supplied to the second opening 1102 for backwashing through the first backwash flow channel 10031 and the third backwash flow channel 10033, forming a dual-channel backwash water supply effect. Accordingly, when the control valve 10 is in the backwash working position, the raw water flows in from the water inlet 1106 of the valve body 11 of the control valve 10 under the action of water pressure, and flows to the second opening 1102 of the valve body 11 through the first backwash flow channel 10031 and the third backwash flow channel 10033, so that the raw water flows to the second connecting opening 202 of the softening device 20 through the second opening 1102, so as to reversely wash the softening material of the softening device 20, and the obtained sewage further flows out through the first connecting opening 201 and flows to the sewage discharge opening 1113 through the second backwash flow channel 10032. When the control valve 10 of the water softener according to the first embodiment of the utility model is controlled to be in the backwash working position, the water softener of the utility model is controlled to be in its backwash working state. In addition, when the control valve 10 is in the backwash working position, the valve core 12 of the control valve 10 further forms a second raw water supply flow channel 10002, wherein the second raw water supply flow channel 10002 is respectively connected with the water inlet 1106 and the water outlet 1104 of the valve body 11, so that when the control valve 10 is in the backwash working position, raw water flows in from the water inlet 1106 of the valve body 11 of the control valve 10 under the action of water pressure, and flows to the water outlet 1104 through the second raw water supply flow channel 10002, so that when the water softener of the utility model is controlled to be in its backwash working state, raw water can be supplied.

Correspondingly, when the control valve 10 is in the water replenishment working position, raw water flows in from the water inlet 1106 of the valve body 11 of the control valve 10 under the action of water pressure, and flows to the first opening 1101 of the valve body 11 through the first water replenishment channel 10041, so that the raw water flows to the first connecting opening 201 of the softening device 20 through the first opening 1101, so that it is softened to obtain softened water, and the obtained softened water further flows out through the second connecting opening 202 and flows to the second jet opening 1112 through the second opening 1102 and the second water replenishment channel 10042, and then flows into the brine tank 31 through the injection port 183 of the ejector 18, the salt absorption port 181 and the salt absorption pipe 184 in turn for water replenishment. When the control valve 10 of the water softener according to the first embodiment of the utility model is controlled to be in the water replenishment working position, the water softener of the utility model is controlled to be in its water replenishment working state. In addition, since the water replenished to the salt liquid tank has been softened and processed into softened water, the water replenished to the salt liquid tank is soft water, and the softened water replenishment is beneficial to reducing the hardness of the regeneration solution itself, which is beneficial to saving salt when regenerating the softening material. Finally, when the control valve 10 is in the water replenishment working position, the valve core 12 of the control valve 10 further forms a third raw water supply channel 10003, wherein the third raw water supply channel 10003 is respectively connected with the water inlet 1106 and the water outlet 1104 of the valve body 11, so that when the control valve 10 is in the water replenishment working position, raw water flows in from the water inlet 1106 of the valve body 11 of the control valve 10 under the action of water pressure, and flows to the water outlet 1104 through the third raw water supply channel 10003, so that when the water softener of the utility model is controlled to be in its water replenishment working state, raw water can be supplied.

When the control valve 10 of the water softener according to the first embodiment of the utility model is controlled to be in the forward washing position, the water softener of the utility model is controlled to be in its forward washing working state. In addition, when the control valve 10 is in the normal wash working position, the valve core 12 of the control valve 10 further forms a fourth raw water supply channel 10004, wherein the fourth raw water supply channel 10004 is respectively connected with the water inlet 1106 and the water outlet 1104 of the valve body 11, so that when the control valve 10 is in the normal wash working position, raw water flows in from the water inlet 1106 of the valve body 11 of the control valve 10 under the action of water pressure, and flows to the water outlet 1104 through the fourth raw water supply channel 10004, so that when the water softener of the utility model is controlled to be in its normal wash working state, raw water can be supplied.

As shown in the accompanying drawings Fig. 10B and Fig. 12B As shown, when the plane valve 10 is in the regeneration working position, the seventh channel 107 is connected to the first channel 101, and the third channel 103 and the fourth channel 104 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122. Although the seventh channel 107 is connected to the first channel 101, a flow channel allowing water to flow through cannot be formed.

[0223] It is worth noting that Fig.9A and Fig. 10AAs shown, when the planar valve 10 is in the softening working position, the generated soft water flows from the second channel 102 through the seventh channel 107 to the fourth channel 104, and from the third channel 103 through the eighth channel 108 to the fifth channel 105, and the first channel 101, the fourth channel 104, the second channel 102, the second jet channel 1012, the third channel 103, the fifth channel 105 and the first jet channel 1011 of the planar valve 10 are arranged in this order clockwise (or counterclockwise) on the edge portion 12102 of the first fluid control surface 1210 of the fixed valve plate 121. Therefore, according to the first embodiment of the utility model, the corresponding channels of the plane valve 10 of the water softener participating in the softened water supply and the raw water supply (the first channel 101, the fourth channel 104, the second channel 102, the third channel 103 and the fifth channel 105 of the fixed valve plate 121 of the plane valve 10, and the sixth channel 106, the seventh channel 107 and the eighth channel 108 of the movable valve plate 122 of the plane valve 10) are respectively distributed in a single circle on the first fluid control surface 1210 of the fixed valve plate 121 and the second fluid control surface 1220 of the movable valve plate 122, and the second channel 102 and the third channel 103 are arranged at intervals from each other, and the seventh channel 107 and the eighth channel 108 are conducting blind holes. The water pressure carried by the softened water obtained after the raw water is softened by the softening device 20 acts on two widely separated parts of the movable valve plate 122 of the plane valve 10 of the water softener according to the first embodiment of the utility model, so that the two different parts of the movable valve plate 122 are subjected to the softened water pressure, thereby effectively offsetting the part of the raw water pressure in the opposite direction on which the movable valve plate 122 is subjected. This not only makes it easier for the movable valve plate 122 of the plane valve 10 of the water softener according to the first embodiment of the utility model to rotate, but also overcomes the defect that the movable valve plate of the existing plane valve used for the water softener is subjected to the softened water pressure on only one side, resulting in unstable rotation, so that the rotation of the movable valve plate 122 of the plane valve 10 of the water softener according to the first embodiment of the utility model is more stable. Secondly, according to the first embodiment of the utility model, the corresponding channels participating in the softened water supply and the raw water supply of the planar valve 10 of the water softener are distributed in a single circle on the first fluid control surface 1210 of the fixed valve plate 121 and the second fluid control surface 1220 of the movable valve plate 122. Not only can the corresponding channels participating in the softened water supply and the raw water supply of the planar valve 10 be extended radially as much as possible to improve the utilization rate of the first fluid control surface 1210 of the fixed valve plate 121 and the second fluid control surface 1220 of the movable valve plate 122 and increase the softened water flow rate, but also the shape of the corresponding channels of the planar valve 10 can be made more regular and the water sealing effect of the corresponding channels can be improved, thereby solving the problem of water leakage of the planar valve.Thirdly, the softened water supply channel of the plane valve 10 of the water softener according to the first embodiment of the utility model is split into two independent water outlet channels (the fourth channel 104 and the fifth channel 105), which also reduces the difficulty of water sealing when the single aperture of the water outlet channel is large, and helps to solve the problem of easy leakage of the plane valve. Therefore, the plane valve 10 of the water softener according to the first embodiment of the utility model not only overcomes the technical bias of the multi-circle distribution of the channels involved in the softened water supply and the raw water supply of the fixed valve plate of the existing control valve for the water softener, but also further has advantages that all existing control valves for water softeners do not have. Accordingly, the planar valve 10 of the water softener according to the first embodiment of the utility model can not only control a higher raw water treatment speed and softened water supply flow, significantly improve the utilization rate of the first fluid control surface 1210 of the fixed valve plate 121 and the second fluid control surface 1220 of the movable valve plate 122, but also enable the movable valve plate 122 to rotate more easily and more smoothly when switching from the softening working position to the adjacent working position or from the corresponding adjacent working position to the softening working position, and even help prevent water leakage.

[0224] As shown in the attached picture Fig. 10C , FIG. 11G to FIG. 11J and Fig. 12C As shown, according to the first embodiment of the utility model, the movable valve plate 122 of the plane valve 10 of the water softener can rotate relative to the fixed valve plate 121 so that the plane valve 10 has a backwash working position. When the plane valve 10 is in the backwash working position, the sixth channel 106 of the plane valve 10 is connected with the third channel 103, thereby forming the first backwash flow channel 10031 respectively connected to the water inlet 1106 and the second opening 1102; the sixth channel 106 of the plane valve 10 is further connected to the fifth channel 105, and the fifth channel 105 is connected to the fourth channel 104 through the conducting channel 113, and the eighth channel 108 is respectively connected to the second channel 102 and the fourth channel 104, thereby forming the first backwash flow channel 10031 respectively connected to the water inlet 1106 and the second opening 1102. The third backwash flow channel 10033 connected to the second opening 1102, that is, the raw water entering the water inlet 1106 flows to the fourth channel 104 through the sixth channel 106, the fifth channel 105 and the conducting channel 113 in sequence, and then flows into the second channel 102 and flows to the second opening 1102 through the eighth channel 108; the sewage channel 1013 is connected to the first channel 101, thereby forming the second backwash flow channel 10032 connected to the first opening 1101 and the sewage opening 1113 respectively; the sixth channel 106 of the plane valve 10 is connected to the fifth channel 105, thereby forming the second raw water supply flow channel 10002 connected to the water inlet 1106 and the water outlet 1104 of the valve body 11 respectively. As shown in the attached figure Fig. 10C and Fig. 12C As shown, when the plane valve 10 is in the backwash working position, the seventh channel 107 is connected to the first jet channel 1011, and the second jet channel 1012 is blocked by the second fluid control surface 1220 of the movable valve plate 122. Although the seventh channel 107 is connected to the first jet channel 1011, a flow channel allowing water to flow through cannot be formed.

[0225] As shown in the attached picture Fig. 10D , Figure 11K and Fig.12D As shown, according to the first embodiment of the utility model, the movable valve plate 122 of the plane valve 10 of the water softener can rotate relative to the fixed valve plate 121 so that the plane valve 10 has a water replenishment working position. When the plane valve 10 is in the water replenishment working position, the sixth channel 106 of the plane valve 10 is connected with the first channel 101, thereby forming the first water replenishment flow channel 10041 respectively connected to the water inlet 1106 and the first opening 1101, and the seventh channel 107 is respectively connected to the second channel 102 and the second jet channel 1012, thereby forming the second water replenishment flow channel 10042 respectively connected to the second opening 1102 and the second jet opening 1112. The sixth channel 106 of the plane valve 10 is further connected to the fourth channel 104, thereby forming the third raw water supply channel 10003 which is connected to the water inlet 1106 and the water outlet 1104 of the valve body 11 respectively. Fig. 10D and Fig.12D As shown, when the plane valve 10 is in the water replenishment working position, the eighth channel 108 is connected to the fifth channel 105, the first jet channel 1011 and the third channel 103 are blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sewage channel 1013 is blocked by the first fluid control surface 1210 of the fixed valve plate 121. Although the eighth channel 108 is connected to the fifth channel 105, a flow channel that allows water to flow cannot be formed.

[0226] As shown in the attached picture Fig. 10E , Fig.11L , Fig.11M and Fig.12EAs shown, the movable valve disc 122 of the plane valve 10 of the water softener according to the first embodiment of the utility model can rotate relative to the fixed valve disc 121 so that the plane valve 10 has a positive wash working position. When the plane valve 10 is in the positive wash working position, the sixth channel 106 of the plane valve 10 is connected with the first channel 101, thereby forming the first positive wash flow channel 10051 respectively connected with the water inlet 1106 and the first opening 1101, and the sewage channel 1013 is connected with the second channel 102, thereby forming the second positive wash flow channel 10052 respectively connected with the second opening 1102 and the sewage opening 1113. As shown in the accompanying drawings Fig. 10E , Fig.11L , Fig.11M and Fig.12E As shown, the sixth channel 106 of the plane valve 10 is connected to the first channel 101, and the seventh channel 107 of the plane valve 10 is respectively connected to the first channel 101 and the fourth channel 104, thereby forming the fourth raw water supply channel 10004 respectively connected to the water inlet 1106 and the water outlet 1104 of the valve body 11, that is, the raw water entering the water inlet 1106 flows to the water outlet 1104 through the sixth channel 106, the first channel 101, the seventh channel 107, the fourth channel 104, and the conducting channel 113 in sequence. As shown in the accompanying drawings Fig. 10E and Fig.12E As shown, when the plane valve 10 is in the normal wash working position, the eighth channel 108 is connected to the third channel 103, and the fifth channel 105, the first jet channel 1011 and the second jet channel 1012 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122. Although the eighth channel 108 is connected to the third channel 103, a flow channel allowing water to flow through cannot be formed.

[0227] In summary, the plane valve 10 of the water softener according to the first embodiment of the utility model can not only control the water softener to supply water (softened water or raw water) in each working state, but also improve the softening efficiency and generate a larger flow of softened water, while making the movable valve plate 122 easier to rotate and more stable, and reducing the possibility of water leakage. Therefore, a single plane valve 10 of the water softener of the utility model can control the water softener of the utility model to realize the functions of raw water softening, softening material regeneration, adding softened water to the salt liquid tank and backwashing softening materials. What is particularly rare is that a single plane valve 10 of the water softener of the utility model can realize the above functions without changing any structure of the existing double-opening softening device.

[0228] As shown in the attached picture 7A to 9BAs shown, the first fluid control surface 1210 of the fixed valve plate 121 of the plane valve 10 of the water softener according to the first embodiment of the utility model has a center portion 12101 shown by a dotted line in the figure and an edge portion 12102 extending outward from the center portion 12101, wherein the center portion 12101 and the edge portion 12102 are arranged at the top end portion 1214 of the fixed valve plate 121, and the edge portion 12102 of the first fluid control surface 1210 (or the portion outside the center portion 12101) is equally divided into a first portion 1201 shown by a dotted line, a second portion 1202, a third portion 1203, a fourth portion 1204, a fifth portion 1205, a sixth portion 1206, a seventh portion 1207, an eighth portion 1208, a ninth portion 1209 and a tenth portion 1210. The second fluid control surface 1220 of the movable valve plate 122 of the planar valve 10 has a central area 12201 shown by a dashed line in the figure and an edge area 12202 extending outward from the central area 12201, wherein the central area 12201 and the edge area 12202 are arranged at the bottom end 1221 of the movable valve plate 122, and the edge area 12202 (the part outside the central area 12201) of the second fluid control surface 1220 is equally divided into a first area 2001 shown by a dashed line, a second area 2002, a third area 2003, a fourth area 2004, a fifth area 2005, a sixth area 2006, a seventh area 2007, an eighth area 2008, a ninth area 2009 and a tenth area 20010;The first channel 101 extends downward from the first part 1201 and the second part 1202 of the first fluid control surface 1210 of the fixed valve plate 121, the fourth channel 104 extends downward from the third part 1203 of the first fluid control surface 1210 of the fixed valve plate 121, the second channel 102 extends downward from the fourth part 1204 of the first fluid control surface 1210 of the fixed valve plate 121, the second jet channel 1012 extends downward from the fifth part 1205 of the first fluid control surface 1210 of the fixed valve plate 121, the third channel 103 extends downward from the seventh part 1207 of the first fluid control surface 1210 of the fixed valve plate 121, the fifth channel 105 extends downward from the seventh part 1208 of the first fluid control surface 1210 of the fixed valve plate 121 The eighth portion 1208 extends downward, the first jet channel 1011 extends downward from the ninth portion 1209 of the first fluid control surface 1210 of the fixed valve disc 121, the sixth channel 106 extends upward from the first area 2001 and the second area 2002 of the second fluid control surface 1220 of the movable valve disc 122, the seventh channel 107 extends upward from the third area 2003 and the fourth area 2004 of the second fluid control surface 1220 of the movable valve disc 122, the drain channel 1013 extends upward from the fifth area 2005 of the second fluid control surface 1220 of the movable valve disc 122, and the eighth channel 108 extends upward from the seventh area 2007 and the eighth area 2008 of the second fluid control surface 1220 of the movable valve disc 122. ;

[0229] Therefore, according to the first embodiment of the utility model, the first channel 101, the fourth channel 104, the second channel 102, the second jet channel 1012, the third channel 103, the fifth channel 105 and the first jet channel 1011 of the plane valve 10 of the water softener are arranged on the first fluid control surface 1210 and the sixth channel 106, the seventh channel 107, the drain channel 1013 and the eighth channel 108 of the plane valve 10 are arranged on the second fluid control surface 1220 of the movable valve plate 122. When the first channel 101 of the plane valve 10 of the water softener according to the first embodiment of the utility model is distributed at two equally divided positions of the first fluid control surface 1210 (two of the 10 equally divided positions of the first fluid control surface 1210), the second channel 102 and the fourth channel 104 of the plane valve 10 are respectively distributed at one equally divided position of the first fluid control surface 1210, and the third channel 103 and the fifth channel 105 of the plane valve 10 are respectively distributed at one equally divided position of the first fluid control surface 1210. The six channels 106 are distributed at two equally divided positions of the second fluid control surface 1220 (two of the 10 equally divided positions of the second fluid control surface 1220), the seventh channel 107 of the plane valve 10 is distributed at two equally divided positions of the second fluid control surface 1220, and the eighth channel 108 of the plane valve 10 is distributed at two equally divided positions of the second fluid control surface 1220, which can realize the sixth channel 106, the seventh channel 107, the drain channel 1013, the eighth channel 108 of the plane valve 10 and the first channel 10 The fourth channel 101, the fourth channel 104, the second channel 102, the second jet channel 1012, the third channel 103, the fifth channel 105, and the first jet channel 1011 are selectively connected at different working positions, and when the water softener of the utility model softens raw water, most of the area of ​​the first fluid control surface 1210 of the planar valve 10 of the water softener of the utility model (excluding the intervals between the channels distributed on the first fluid control surface 1210 and the central part 12101 that does not participate in the conduction, which is close to 6 / 10 of the area) participates in the flow of water. Since the raw water channel for providing raw water to the softening device 20 of the water softener of the utility model is composed of the first channel 101 and the sixth channel 106, wherein the first channel 101 occupies 2 equal parts of the first fluid control surface 1210 (close to 1 / 5 of the total area of ​​the first fluid control surface 1210), and the sixth channel 106 occupies 2 equal parts of the second fluid control surface 1220 (close to 1 / 5 of the total area of ​​the second fluid control surface 1220), it is significantly higher than the ratio of the total area of ​​the first fluid control surface and the second fluid control surface of the planar valve occupied by the raw water channel for providing raw water in the existing planar valve for water softeners.Correspondingly, the outlet channel (the second channel 102 and the third channel 103) connected to the softening device 20 also occupies 2 equal parts of the first fluid control surface 1210 (close to 1 / 5 of the total area of ​​the first fluid control surface 1210), and the soft water supply channel (the fourth channel 104 and the fifth channel 105) connected to the water outlet 1104 also occupies 2 equal parts of the first fluid control surface 1210 (close to 1 / 5 of the total area of ​​the first fluid control surface 1210). At this time, the movable valve plate 122 needs to have a The seventh channel 107, which is mutually conductive with the second channel 102 and the fourth channel 104, and the eighth channel 108, which is mutually conductive with the third channel 103 and the fifth channel 105, can realize the dual-channel water supply function. The seventh channel 107 also occupies 2 equal parts of the second fluid control surface 1220 (close to 1 / 5 of the total area of ​​the second fluid control surface 1220), and the eighth channel 108 also occupies 2 equal parts of the second fluid control surface 1220 (close to 1 / 5 of the total area of ​​the second fluid control surface 1220). Therefore, most of the areas (close to 6 / 10 of the area) of the first fluid control surface 1210 and the second fluid control surface 1220 of the plane valve 10 of the water softener of the utility model participate in the flow of water. It can be understood that only when most of the areas of the first fluid control surface 1210 and the second fluid control surface 1220 cooperate with each other to participate in the flow of water can the water supply capacity with a large flow rate be realized. In other words, the total cross-sectional area of ​​the inflow channel of the plane valve 10 of the water softener of the utility model that supplies raw water to the softening device of the water softener and the total cross-sectional area of ​​the outflow channel of the softened water obtained can become larger as a proportion of the total flow control surface area of ​​the fixed valve plate and the movable valve plate, thereby significantly improving the softening water processing speed and softened water flow rate of the water softener of the utility model. That is to say, the above-mentioned arrangement of the first channel 101, the fourth channel 104, the second channel 102, the second jet channel 1012, the third channel 103, the fifth channel 105 and the first jet channel 1011 of the plane valve 10 of the water softener of the utility model on the first fluid control surface 1210, the above-mentioned arrangement of the sixth channel 106, the seventh channel 107, the sewage channel 1013 and the eighth channel 108 of the plane valve 10 on the second fluid control surface 1220 of the movable valve plate 122, the plane The equally divided positions of the first fluid control surface 1210 occupied by the first channel 101, the fourth channel 104, the second channel 102, the second jet channel 1012, the third channel 103, the fifth channel 105 and the first jet channel 1011 of the face valve 10 and the equally divided positions of the second fluid control surface 1220 of the movable valve plate 122 occupied by the sixth channel 106, the seventh channel 107, the sewage channel 1013 and the eighth channel 108 of the plane valve 10 determine the selective connection mode thereof in different working positions.

[0230] As shown in the attached picture 7A to 9B As shown, exemplarily, the edge portion 12102 of the first fluid control surface 1210 is divided into the first portion 1201, the second portion 1202, the third portion 1203, the fourth portion 1204, the fifth portion 1205, the sixth portion 1206, the seventh portion 1207, the eighth portion 1208, the ninth portion 1209 and the tenth portion 12010 in a clockwise direction, and the edge area 12202 of the second fluid control surface 1220 of the movable valve plate 122 of the planar valve 10 is divided into the first area 2001, the second area 2002, the third area 2003, the fourth area 2004, the fifth area 2005, the sixth area 2006, the seventh area 2007, the eighth area 2008, the ninth area 2009 and the tenth area 20010 in a clockwise direction. In other words, the first fluid control surface 1210 of the fixed valve plate 121 of the plane valve 10 is divided into ten equal parts, and the second fluid control surface 1220 of the movable valve plate 122 of the plane valve 10 is divided into ten equal parts. 7A to 9B , Fig. 10A and Fig. 12AAs shown, when the movable valve plate 122 of the plane valve 10 is rotated to the point where the first and second portions (the first area 2001 and the second area 2002) of the second fluid control surface 1220 of the movable valve plate 122 are aligned with the first and second portions (the first portion 1201 and the second portion 1202) of the first fluid control surface 1210 of the fixed valve plate 121, the third and fourth portions (the third area 2003 and the fourth area 2004) of the second fluid control surface 1220 of the movable valve plate 122 of the plane valve 10 are aligned with the third and fourth portions (the third portion 1201 and the second portion 1202) of the first fluid control surface 1210 of the fixed valve plate 121, respectively. 203 and the fourth portion 1204), the fifth equal portion (the fifth region 2005) of the second fluid control surface 1220 of the movable valve plate 122 of the plane valve 10 is directly opposite to the fifth equal portion (the fifth portion 1205) of the first fluid control surface 1210 of the fixed valve plate 121, and the seventh and eighth equal portions (the seventh region 2007 and the eighth region 2008) of the second fluid control surface 1220 of the movable valve plate 122 of the plane valve 10 are directly opposite to the seventh and eighth equal portions (the seventh portion 1207 and the eighth portion 1208) of the first fluid control surface 1210 of the fixed valve plate 121, respectively, so that the sixth channel 106 of the plane valve 10 The seventh channel 107 is connected to the first channel 101, the seventh channel 107 is connected to the second channel 102 and the fourth channel 104 respectively, the sewage channel 1013 is blocked by the first fluid control surface 1210 of the fixed valve plate 121, the eighth channel 108 is connected to the third channel 103 and the fifth channel 105 respectively, and the first jet channel 1011 and the second jet channel 1012 are blocked by the second fluid control surface 1220 of the movable valve plate 122 respectively, so as to allow raw water to flow in from the water inlet 1106 of the valve body 11, flow to the first opening 1101 through the sixth channel 106 and the first channel 101, and further flow into the first communication opening 201 of the softening device 20. The softening device 20, after being softened by the softening device 20, flows out from the second connecting opening 202 of the softening device 20 and further flows into the second opening 1102. The water flowing into the second opening 1102 is divided into two paths and flows to the water outlet 1104. One path flows through the second opening 1102, the second channel 102, the seventh channel 107, the fourth channel 104, and the conducting channel 113 in sequence to flow to the water outlet 1104. The other path flows through the second opening 1102, the third channel 103, the eighth channel 108, and the fifth channel 105 in sequence to flow to the water outlet 1104. The softened water flowing out of the water outlet 1104 is further provided to the user. Accordingly, the water softener is in the softening working state at this time. As shown in the accompanying drawing 7A to 9B , Fig. 10B and Fig. 12BAs shown, when the movable valve plate 122 of the plane valve 10 is rotated to the point where the first and second portions (the first area 2001 and the second area 2002) of the second fluid control surface 1220 of the movable valve plate 122 are aligned with the eighth and ninth portions (the eighth portion 1208 and the ninth portion 1209) of the first fluid control surface 1210 of the fixed valve plate 121, the third and fourth portions (the third area 2003 and the fourth area 2004) of the second fluid control surface 1220 of the movable valve plate 122 of the plane valve 10 are aligned with the tenth and first portions (the tenth portion 12010 and the first portion 12011) of the first fluid control surface 1210 of the fixed valve plate 121, respectively. The fifth equal part (the fifth area 2005) of the second fluid control surface 1220 of the movable valve plate 122 of the plane valve 10 is directly opposite to the second equal part (the second part 1202) of the first fluid control surface 1210 of the fixed valve plate 121, and the seventh equal part and the eighth equal part (the seventh area 2007 and the eighth area 2008) of the second fluid control surface 1220 of the movable valve plate 122 of the plane valve 10 are directly opposite to the fourth equal part and the fifth equal part (the fourth part 1204 and the fifth part 1205) of the first fluid control surface 1210 of the fixed valve plate 121, respectively, so that the sixth channel 106 of the plane valve 10 is directly opposite to the fifth channel 105 and the first channel 106, respectively.

[0247] As shown in the attached picture 9A to 10E , FIG. 18A to FIG. 19E , Fig.20F , Fig. 20J and Figure 20MAs shown, the structural difference between the plane valve 10 and the plane valve 10A of the water softener according to the first embodiment of the utility model lies in that the drain channel 1013 of the plane valve 10 is different from the drain channel 1013A of the plane valve 10A, and the drain channel 1014A of the plane valve 10A participates in draining: the drain channel 1014A is arranged in the central portion 12101A of the first fluid control surface 1210A, the drain channel 1013A is arranged in the fifth area 2005A and the central area 12201A of the second fluid control surface 1220A, and the drain channel 1013A is connected to the drain channel 1014A, and the drain channel 1013A is a conducting blind hole. Therefore, when the plane valve 10 and the plane valve 10A of the water softener according to the first embodiment of the utility model are in the corresponding working positions, the alignment method of the equal parts of the second fluid control surface 1220 of the movable valve plate 122 of the plane valve 10 and the equal parts of the first fluid control surface 1210 of the fixed valve plate 121 is the same as the alignment method of the equal parts of the second fluid control surface 1220A of the movable valve plate 122A of the plane valve 10A and the equal parts of the first fluid control surface 1210A of the fixed valve plate 121A. As described above, the difference in the functional realization of the plane valve 10 and the plane valve 10A of the water softener according to the first embodiment of the utility model is that the plane valve 10A of the water softener according to the first embodiment of the utility model discharges sewage through the sewage discharge channel 1013A, the discharge channel 1014A and the sewage discharge opening 1113A, and the discharge channel 1014A is arranged in the central part 12101A of the first fluid control surface 1210A, the sewage discharge channel 1013A is arranged in the fifth area 2005A and the central area 12201A of the second fluid control surface 1220A, the sewage discharge channel 1013A is connected to the discharge channel 1014A, and the sewage discharge opening 1113A is connected to the drain channel 1014A. The sewage channel 1013A is a conducting blind hole. Accordingly, when the plane valve 10A is in the regeneration working position, the third regeneration flow channel 10023A is formed by the first channel 101A, the sewage channel 1013A and the discharge channel 1014A being connected; when the plane valve 10A is in the backwash working position, the second backwash flow channel 10032A is formed by the first channel 101A, the sewage channel 1013A and the discharge channel 1014A being connected; when the plane valve 10A is in the forward wash working position, the second forward wash flow channel 10052A is formed by the second channel 102A, the sewage channel 1013A and the discharge channel 1014A being connected.

[0248] In addition, the first channel 101, the fourth channel 104, the second channel 102, the second jet channel 1012, the third channel 103, the fifth channel 105 and the first jet channel 1011 of the plane valve 10 of the water softener according to the first embodiment of the utility model are arranged on the first fluid control surface 1210 and the sixth channel 106, the seventh channel 107, the drain channel 1013 and the eighth channel 108 of the plane valve 10 are arranged on the second fluid control surface 1220 of the movable valve plate 122, and the first channel 101A, the fourth channel 104A, the second channel 102A, the second jet channel 1012A, the third channel 103A, the fifth channel 105A and the first jet channel 1011 of the plane valve 10A of the water softener according to the first embodiment of the utility model are arranged on the first fluid control surface 1210 and the sixth channel 106, the seventh channel 107, the drain channel 1013 and the eighth channel 108 of the plane valve 10 are arranged on the second fluid control surface 1220 of the movable valve plate 122. The above-mentioned arrangement of the channel 1011A on the first fluid control surface 1210A is basically the same as the above-mentioned arrangement of the sixth channel 106A, the seventh channel 107A, the drain channel 1013A and the eighth channel 108A of the planar valve 10A on the second fluid control surface 1220A of the movable valve plate 122A (except that the drain channel 1013A extends from the fifth area 2005A of the second fluid control surface 1220A to the central area 12201A). Therefore, when the water softener of the present invention softens raw water, most of the area of ​​the first fluid control surface 1210A of the planar valve 10A of the water softener of the present invention (excluding the intervals between the channels distributed on the first fluid control surface 1210A and the central part 12101A that does not participate in conduction, which is close to 6 / 10 of the area) participates in the flow of water. Since the raw water channel for providing raw water to the softening device 20 of the water softener of the utility model is composed of the first channel 101A and the sixth channel 106A, wherein the first channel 101A occupies 2 equal parts of the first fluid control surface 1210A (close to 1 / 5 of the total area of ​​the first fluid control surface 1210A), and the sixth channel 106A occupies 2 equal parts of the second fluid control surface 1220A (close to 1 / 5 of the total area of ​​the second fluid control surface 1220A), it is significantly higher than the ratio of the total area of ​​the first fluid control surface and the second fluid control surface of the planar valve occupied by the raw water channel for providing raw water in the existing planar valve for water softeners.Correspondingly, the outlet channel (the second channel 102A and the third channel 103A) connected to the softening device 20 also occupies 2 equal parts of the first fluid control surface 1210A (close to 1 / 5 of the total area of ​​the first fluid control surface 1210A), and the soft water supply channel (the fourth channel 104A and the fifth channel 105A) connected to the water outlet 1104 also occupies 2 equal parts of the first fluid control surface 1210A (close to 1 / 5 of the total area of ​​the first fluid control surface 1210A). At this time, the movable valve plate 122A needs to have a connection with the The seventh channel 107A, which is mutually conductive with the second channel 102A and the fourth channel 104A, and the eighth channel 108A, which is mutually conductive with the third channel 103A and the fifth channel 105A, can realize the dual-channel water supply function. The seventh channel 107A also occupies 2 equal parts of the second fluid control surface 1220A (close to 1 / 5 of the total area of ​​the second fluid control surface 1220A), and the eighth channel 108A also occupies 2 equal parts of the second fluid control surface 1220A (close to 1 / 5 of the total area of ​​the second fluid control surface 1220A). Therefore, most of the areas (close to 6 / 10 of the area) of the first fluid control surface 1210A and the second fluid control surface 1220A of the plane valve 10A of the water softener of the utility model participate in the flow of water. It is understandable that only when the first fluid control surface 1210A and the second fluid control surface 1220A both have a large area that cooperates with each other to participate in the flow of water, can the water supply capacity with a large flow rate be achieved. In other words, the total cross-sectional area of ​​the inflow channel of the plane valve 10A of the water softener of the utility model that supplies raw water to the softening device of the water softener and the total cross-sectional area of ​​the outflow channel of the softened water obtained can be increased as a proportion of the total area of ​​the flow control surface of the fixed valve plate and the moving valve plate, thereby significantly improving the softening water processing speed and softening water flow rate of the water softener of the utility model.

[0249] As shown in the attached picture FIG. 22A to FIG. 24J As shown, the control valve 10B of the water softener according to the second embodiment of the utility model is explained, and the control valve 10B includes a valve body 11B and a valve core 12B, wherein the valve body 11B forms a valve cavity 110B, a first opening 1101B, a second opening 1102B, a first jet opening 1111B, a second jet opening 1112B, a water outlet 1104B, a water inlet 1106B and a The sewage opening 1113B, wherein the valve core 12B is arranged in the valve cavity 110B, wherein the first opening 1101B of the valve body 11B is suitable for being connected with the first connecting opening 201 of the softening device 20, the second opening 1102B of the valve body 11B is suitable for being connected with the second connecting opening 202 of the softening device 20, and the water inlet 1106B of the valve body 11B is suitable for being connected with a raw water source (for example, a tap water pipe).

[0250] As shown in the attached picture FIG. 22A to FIG. 23B As shown, the control valve 10B of the water softener according to the second embodiment of the utility model further has an ejector 18B, wherein the ejector 18B has an ejection port 182B suitable for being connected to the first ejection opening 1111B of the valve body 11B, an ejection port 183B suitable for being connected to the second ejection opening 1112B of the valve body 11B, and a salt absorption port 181B respectively connected to the ejection port 182B and the ejection port 183B. When water flow, such as tap water flow, flows from the ejection port 182B of the ejector 18B to the ejection port 183B of the ejector 18B, negative pressure occurs at the salt absorption port 181B of the ejector 18B, so that the regeneration solution can flow from the salt absorption port 181B of the ejector 18B to the ejection port 183B of the ejector 18B. Correspondingly, the salt absorption port 181B of the ejector 18B is respectively connected with the ejection port 182B and the ejection port 183B of the ejector 18B.

[0251] As shown in the attached picture Fig.22A As shown, the water softener according to the second embodiment of the utility model further includes a salt absorption pipe 184 and a salt solution tank 31, wherein one end of the salt absorption pipe 184 is connected to the salt absorption port 181B, and the other end of the salt absorption pipe 184 is connected to the salt solution tank 31, so that the salt solution can be provided to the salt absorption port 181B through the salt absorption pipe 184 or the water flow can flow from the salt absorption port 181B and flow through the salt absorption pipe 184 to the salt solution tank 31 to replenish the salt solution tank 31.

[0252] As shown in the attached picture FIG. 29A to FIG. 29C and Fig. 30AAs shown, the control valve 10B of the water softener according to the second embodiment of the utility model has a softening working position, wherein when the control valve 10B is in the softening working position, the valve core 12B of the control valve 10B forms a first softening flow channel 10011B, a second softening flow channel 10012B, a third softening flow channel 10013B and a fourth softening flow channel 10014B, wherein the first softening flow channel 10011B is respectively connected to the valve body The water inlet 1106B of the valve body 11B is connected to the first opening 1101B, the fourth softening flow channel 10014B is respectively connected to the water inlet 1106B and the first opening 1101B of the valve body 11B, the second softening flow channel 10012B is respectively connected to the second opening 1102B and the water outlet 1104B, and the third softening flow channel 10013B is respectively connected to the second opening 1102B and the water outlet 1104B. Accordingly, when the control valve 10B is in the softening working position, since the water inlet 1106B and the first opening 1101B are connected through the first softening flow channel 10011B and the fourth softening flow channel 10014B respectively, the raw water flows in from the water inlet 1106B of the valve body 11B of the control valve 10B under the action of water pressure, flows to the first opening 1101B of the valve body 11B through the first softening flow channel 10011B and the fourth softening flow channel 10014B respectively, and further flows from the first connecting opening of the softening device 20 201 flows into the softening device 20, and the softened water after the softening treatment of the softening device 20 flows out from the second connecting opening 202 of the softening device 20 and further flows into the second opening 1102B. Since the second opening 1102B and the water outlet 1104B are connected through the second softening flow channel 10012B and the third softening flow channel 10013B respectively, the softened water flowing into the second opening 1102B flows to the water outlet 1104B through the second softening flow channel 10012B and the third softening flow channel 10013B respectively and is provided. It can be understood that when the control valve 10B of the water softener according to the second embodiment of the utility model is controlled to be in the softening working position, the water softener of the utility model is controlled to be in its softening working state.

[0253] As shown in the attached picture Fig.29D , Fig.29E and Fig. 30BAs shown, the control valve 10B of the water softener according to the second embodiment of the utility model has a regeneration working position, wherein when the control valve 10B is in the regeneration working position, the valve core 12B of the control valve 10B forms a first regeneration flow channel 10021B, a second regeneration flow channel 10022B and a third regeneration flow channel 10023B, wherein the first regeneration flow channel 10021B is respectively connected to the water inlet 1106B and the first jet opening 1111B of the valve body 11B, the second regeneration flow channel 10022B is respectively connected to the first opening 1101B and the second jet opening 1112B, and the third regeneration flow channel 10023B is respectively connected to the second opening 1102B and the sewage opening 1113B. Correspondingly, when the control valve 10B is in the regeneration working position, the raw water flows in from the water inlet 1106B of the valve body 11B of the control valve 10B under the action of water pressure, flows to the first jet opening 1111B of the valve body 11B through the first regeneration flow channel 10021B, and then flows into the jet outlet 182B of the ejector 18B, passes through the ejector 18B jet, and is mixed with the salt solution (such as sodium chloride solution) from the salt absorption port 181B to form a regeneration solution, and the regeneration solution flows into the valve body 11B through the jet outlet 183B of the ejector 18B. The second jet opening 1112B then flows into the first opening 1101B of the valve body 11B through the second regeneration flow channel 10022B, and the regeneration solution flows into the softening device 20 from the first communication opening 201 of the softening device 20, and regenerates the water treatment material or mechanism of the softening device 20, such as softening resin, downstream, and the waste water generated after regeneration flows out from the second communication opening 202 of the softening device 20, and then flows out through the second opening 1102B of the valve body 11B, the third regeneration flow channel 10023B and the sewage opening 1113B in sequence. It can be understood that when the control valve 10B of the water softener according to the second embodiment of the utility model is controlled to be in the regeneration working position, the water softener of the utility model is controlled to be in its regeneration working state. It is worth noting that the waste water generated after regeneration flows out from the sewage opening 1113B. In addition, when the control valve 10B is in the regeneration working position, the valve core 12B of the control valve 10B further forms a first raw water supply channel 10001B, wherein the first raw water supply channel 10001B is respectively connected with the water inlet 1106B and the water outlet 1104B of the valve body 11B, so that when the control valve 10B is in the regeneration working position, raw water can flow in from the water inlet 1106B of the valve body 11B of the control valve 10B under the action of water pressure, and flow to the water outlet 1104B through the first raw water supply channel 10001B, so that when the water softener of the utility model is controlled to be in its regeneration working state, raw water can be supplied.

[0254] As shown in the attached picture Fig.29F , Figure 29G and Fig. 30C As shown, the control valve 10B of the water softener according to the second embodiment of the utility model further has a backwash working position, wherein when the control valve 10B is in the backwash working position, the valve core 12B of the control valve 10B forms a first backwash flow channel 10031B and a second backwash flow channel 10032B, wherein the first backwash flow channel 10031B is respectively connected to the water inlet 1106B and the second opening 1102B of the valve body 11B, and the second backwash flow channel 10032B is respectively connected to the first opening 1101B and the sewage opening 1113B of the valve body 11B.

Optionally, the first channel 101B, the fourth channel 104B, the second channel 102B, the tenth channel 1010B, the second jet channel 1012B, the first jet channel 1011B, the third channel 103B and the fifth channel 105B of the planar valve 10B are arranged counterclockwise in this order on the edge portion 12102B of the first fluid control surface 1210B of the fixed valve plate 121B, and the sixth channel 106B, the seventh channel 107B, the ninth channel 109B, the sewage channel 1013B and the eighth channel 108B of the planar valve 10B are arranged counterclockwise in this order on the second fluid control surface 1220B of the movable valve plate 122B. Preferably, the first channel 101B and the tenth channel 1010B, the second channel 102B and the third channel 103B, the fourth channel 104B and the fifth channel 105B, the first jet channel 1011B, and the second jet channel 1012B of the planar valve 10B are separately arranged on the first fluid control surface 1210B of the fixed valve plate 121B; the sixth channel 106B and the ninth channel 109B, the seventh channel 107B, the sewage channel 1013B, and the eighth channel 108B of the planar valve 10B are separately arranged on the second fluid control surface 1220B of the movable valve plate 122B.

[0261] As shown in the attached picture Fig.28A , FIG. 29A to FIG. 29C and Fig. 30AAs shown, according to the second embodiment of the utility model, the movable valve plate 122B of the plane valve 10B of the water softener can rotate relative to the fixed valve plate 121B so that the plane valve 10B has a softening working position. When the plane valve 10B is in the softening working position, the sixth channel 106B of the plane valve 10B is connected with the first channel 101B, thereby forming the first softening flow channel 10011B respectively connected with the water inlet 1106B and the first opening 1101B, and the seventh channel 107B is respectively connected with the second channel 102B and the fourth channel 104B, from The second softening flow channel 10012B is formed to be connected to the second opening 1102B and the water outlet 1104B respectively, the eighth channel 108B is connected to the third channel 103B and the fifth channel 105B respectively, thereby forming the third softening flow channel 10013B connected to the second opening 1102B and the water outlet 1104B respectively, and the ninth channel 109B of the plane valve 10B is connected to the tenth channel 1010B, thereby forming the fourth softening flow channel 10014B connected to the water inlet 1106B and the first opening 1101B respectively. Fig.28A and Fig. 30AAs shown, when the planar valve 10B is in the softening working position, the first jet channel 1011B and the second jet channel 1012B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, and the sewage discharge channel 1013B is blocked by the first fluid control surface 1210B of the fixed valve plate 121B. Accordingly, when the control valve 10B is in the softening working position, since the water inlet 1106B and the first opening 1101B are connected through the first softening flow channel 10011B and the fourth softening flow channel 10014B respectively, the raw water flows in from the water inlet 1106B of the valve body 11B of the control valve 10B under the action of water pressure, flows to the first opening 1101B of the valve body 11B through the first softening flow channel 10011B and the fourth softening flow channel 10014B respectively, and further flows from the first connecting opening of the softening device 20 201 flows into the softening device 20, and the softened water after the softening treatment by the softening device 20 flows out from the second connecting opening 202 of the softening device 20 and further flows into the second opening 1102B. Since the second opening 1102B and the water outlet 1104B are respectively connected through the second softening flow channel 10012B and the third softening flow channel 10013B, the softened water flowing into the second opening 1102B flows to the water outlet 1104B and is provided through the second softening flow channel 10012B and the third softening flow channel 10013B respectively. In other words, the softened water after the raw water is softened by the softening device 20 flows out from the second connecting opening 202 of the softening device 20 and further flows into the second opening 1102B, and then flows out through the second softening flow channel 10012B formed by the second channel 102B, the seventh channel 107B and the fourth channel 104B and the third softening flow channel 10013B formed by the third channel 103B, the eighth channel 108B and the fifth channel 105B.

[0262] As shown in the attached picture Fig.28B , Fig.29D , Fig.29E and Fig. 30BAs shown, the plane valve 10B of the water softener according to the second embodiment of the utility model further has a regeneration working position. When the plane valve 10B is in the regeneration working position, the ninth channel 109B of the plane valve 10B is connected with the first jet channel 1011B, thereby forming the first regeneration flow channel 10021B respectively connected with the water inlet 1106B and the first jet opening 1111B, and the seventh channel 107B is respectively connected with the second jet channel 1012B and the tenth channel 1010B, thereby forming the second jet opening 1111B respectively connected with the water inlet 1106B and the first jet opening 1111B. The second regeneration flow channel 10022B is connected to the first opening 1101B, the sewage channel 1013B is connected to the third channel 103B, thereby forming the third regeneration flow channel 10023B connected to the second opening 1102B and the sewage opening 1113B, respectively, and the sixth channel 106B of the plane valve 10B is further connected to the fourth channel 104B, thereby forming the first raw water supply flow channel 10001B connected to the water inlet 1106B and the water outlet 1104B of the valve body 11B. As shown in the accompanying drawings Fig.28B and Fig. 30B As shown, when the plane valve 10B is in the regeneration working position, the eighth channel 108B is connected to the first channel 101B, and the second channel 102B and the fifth channel 105B are blocked by the second fluid control surface 1220B of the movable valve plate 122B. Although the eighth channel 108B is connected to the first channel 101B, a flow channel that allows water to flow cannot be formed.

[0263] It is worth noting that Fig.27A and Fig.28AAs shown, when the planar valve 10B is in the softening working position, the generated softened water flows from the second channel 102B through the seventh channel 107B to the fourth channel 104B, and from the third channel 103B through the eighth channel 108B to the fifth channel 105B, and the first channel 101B, the fourth channel 104B, the second channel 102B, the tenth channel 1010B, the second jet channel 1012B, the first jet channel 1011B, the third channel 103B and the fifth channel 105B of the planar valve 10B are arranged clockwise (or counterclockwise) in this order on the edge portion 12102B of the first fluid control surface 1210B of the fixed valve plate 121B. Therefore, according to the second embodiment of the utility model, the corresponding channels of the plane valve 10B of the water softener participating in the softened water supply and the raw water supply (the first channel 101B, the fourth channel 104B, the second channel 102B, the tenth channel 1010B, the third channel 103B and the fifth channel 105B of the fixed valve plate 121B of the plane valve 10B, the sixth channel 106B, the seventh channel 107B, the ninth channel 109B and the eighth channel 108B of the movable valve plate 122B of the plane valve 10B) are respectively distributed in a single circle on the first fluid control surface 1210B of the fixed valve plate 121B and the second fluid control surface 1220B of the movable valve plate 122B, and the second channel 102B and the third channel 103B are spaced apart from each other (the two are even in symmetrical or substantially symmetrical positions), and the seventh channel 107B is arranged at a distance from each other. When B and the eighth channel 108B are conducting blind holes, the water pressure carried by the softened water obtained after the raw water is softened by the softening device 20 can act on the two far-away parts of the movable valve plate 122B of the plane valve 10B of the water softener according to the second embodiment of the utility model, and the upward pressure of the softened water is basically the same, so that the two different parts of the movable valve plate 122B are subjected to the softened water pressure, thereby effectively offsetting the part of the raw water water pressure acting in the opposite direction on the movable valve plate 122B, which not only makes the movable valve plate 122B of the plane valve 10B according to the second embodiment of the utility model easier to rotate, but also overcomes the defect that the movable valve plate of the existing plane valve used for the water softener is only subjected to the softened water pressure on one side, resulting in the unstable rotation, so that the rotation of the movable valve plate 122B of the plane valve 10B of the water softener according to the second embodiment of the utility model is more stable.Secondly, according to the second embodiment of the utility model, the corresponding channels participating in the softened water supply and the raw water supply of the planar valve 10B of the water softener are distributed in a single circle on the first fluid control surface 1210B of the fixed valve plate 121B and the second fluid control surface 1220B of the movable valve plate 122B. Not only can the corresponding channels participating in the softened water supply and the raw water supply of the planar valve 10B be extended radially as much as possible to improve the utilization rate of the first fluid control surface 1210B of the fixed valve plate 121B and the second fluid control surface 1220B of the movable valve plate 122B and increase the softened water flow rate, but also the shape of the corresponding channels of the planar valve 10B can be made more regular and the water sealing effect of the corresponding channels can be improved, thereby solving the problem of water leakage that is prone to occur in the planar valve. Thirdly, the softened water supply channel of the plane valve 10B of the water softener according to the second embodiment of the utility model is split into two independent water outlet channels (the fourth channel 104B and the fifth channel 105B), which also reduces the difficulty of water sealing when the single aperture of the water outlet channel is large, and helps to solve the problem of easy leakage of the plane valve. Therefore, the plane valve 10B of the water softener according to the second embodiment of the utility model not only overcomes the technical bias of the multi-circle distribution of the channels involved in the softened water supply and the raw water supply of the fixed valve plate of the existing control valve for the water softener, but also further has advantages that all existing control valves for water softeners do not have. Accordingly, the plane valve 10B of the water softener according to the second embodiment of the utility model can not only control a higher raw water treatment speed and softened water supply flow, significantly improve the utilization rate of the first fluid control surface 1210B of the fixed valve plate 121B and the second fluid control surface 1220B of the movable valve plate 122B, but also enable the movable valve plate 122B to rotate more easily and more smoothly when switching from the softening working position to the adjacent working position or from the corresponding adjacent working position to the softening working position, and even help prevent water leakage.

When the plane valve 10B is in the backwashing working position, the sixth channel 106B of the plane valve 10B is connected to the third channel 103B, thereby forming the first backwashing flow channel 106B connected to the water inlet 1106B and the second opening 1102B respectively. 031B; the sewage channel 1013B is connected to the tenth channel 1010B, thereby forming the second backwash flow channel 10032B connected to the first opening 1101B and the sewage opening 1113B respectively; the ninth channel 109B of the plane valve 10B is connected to the fourth channel 104B, thereby forming the second raw water supply flow channel 10002B connected to the water inlet 1106B and the water outlet 1104B of the valve body 11B respectively. As shown in the attached figure Fig.28B and Fig. 30B As shown, when the plane valve 10B is in the backwash working position, the seventh channel 107B is connected to the first channel 101B, the eighth channel 108B is connected to the first jet channel 1011B, and the second channel 102B, the fifth channel 105B and the second jet channel 1012B are blocked by the second fluid control surface 1220B of the movable valve plate 122B. Although the seventh channel 107B is connected to the first channel 101B and the eighth channel 108B is connected to the first jet channel 1011B, a flow channel allowing water to flow through cannot be formed.

[0265] As shown in the attached picture Fig.28D , Fig.29H and Fig.30D As shown, according to the second embodiment of the utility model, the movable valve plate 122B of the plane valve 10B of the water softener can rotate relative to the fixed valve plate 121B so that the plane valve 10B has a water replenishment working position. When the plane valve 10B is in the water replenishment working position, the sixth channel 106B of the plane valve 10B is connected with the second jet channel 1012B, thereby forming the first water replenishment flow channel 10041B respectively connected with the water inlet 1106B and the second jet opening 1112B. The ninth channel 109B of the plane valve 10B is further connected with the fifth channel 105B, thereby forming the third raw water supply flow channel 10003B respectively connected with the water inlet 1106B and the water outlet 1104B of the valve body 11B. As shown in the accompanying drawings Fig.28D and Fig.30DAs shown, when the plane valve 10B is in the water replenishment working position, the seventh channel 107B is connected to the third channel 103B, the eighth channel 108B is connected to the second channel 102B and the tenth channel 1010B respectively, the sewage channel 1013B is connected to the first channel 101B, and the fourth channel 104B and the first jet channel 1011B are blocked by the second fluid control surface 1220B of the movable valve plate 122B. Although the seventh channel 107B is connected to the third channel 103B, the eighth channel 108B is connected to the second channel 102B and the tenth channel 1010B respectively, and the sewage channel 1013B is connected to the first channel 101B, a flow channel that allows water to flow through cannot be formed. As shown in the accompanying drawings Fig.28E , Fig.29I , Fig.29J and Fig.30E As shown, according to the second embodiment of the utility model, the movable valve plate 122B of the plane valve 10B of the water softener can rotate relative to the fixed valve plate 121B so that the plane valve 10B has a positive wash working position. When the plane valve 10B is in the positive wash working position, the ninth channel 109B of the plane valve 10B is connected with the first channel 101B, thereby forming the first positive wash flow channel 10051B respectively connected with the water inlet 1106B and the first opening 1101B, and the sewage channel 1013B is connected with the second channel 102B, thereby forming the second positive wash flow channel 10052B respectively connected with the second opening 1102B and the sewage opening 1113B. The ninth channel 109B of the plane valve 10B is connected to the first channel 101B, and the seventh channel 107B of the plane valve 10B is respectively connected to the first channel 101B and the fifth channel 105, thereby forming the fourth raw water supply channel 10004B respectively connected to the water inlet 1106B and the water outlet 1104B of the valve body 11B, that is, the raw water entering the water inlet 1106B flows to the water outlet 1104B through the ninth channel 109B, the first channel 101B, the seventh channel 107B, and the fifth channel 105 in sequence. Fig.28E and Fig.30E As shown, when the plane valve 10B is in the normal washing working position, the eighth channel 108B is connected to the first jet channel 1011B and the second jet channel 1012B respectively, the third channel 103B, the fourth channel 104B and the tenth channel 1010B are blocked by the second fluid control surface 1220B of the movable valve plate 122B respectively, and the sixth channel 106B is blocked by the first fluid control surface 1210B of the fixed valve plate 121B. Although the eighth channel 108B is connected to the first jet channel 1011B and the second jet channel 1012B respectively, it cannot form a flow channel allowing water to flow through.

[0266] In summary, the plane valve 10B of the water softener according to the second embodiment of the utility model can not only control the water softener to supply water (softened water or raw water) in each working state, but also improve the softening efficiency, generate a larger flow of softened water, make the movable valve plate 122B easier to rotate and rotate more smoothly, and reduce the possibility of water leakage. Therefore, a single plane valve 10B of the water softener of the utility model can control the water softener of the utility model to realize the functions of raw water softening, softening material regeneration, adding softened water to the salt liquid tank and backwashing softening materials. What is particularly rare is that a single plane valve 10B of the water softener of the utility model can realize the above functions without changing any structure of the existing double-opening softening device.

[0268] Therefore, according to the second embodiment of the utility model, the first channel 101B, the fourth channel 104B, the second channel 102B, the tenth channel 1010B, the second jet channel 1012B, the first jet channel 1011B, the third channel 103B and the fifth channel 105B of the plane valve 10B of the water softener are arranged on the first fluid control surface 1210B and the sixth channel 106B, the seventh channel 107B, the ninth channel 109B, the drain channel 1013B and the eighth channel 108B of the plane valve 10B are arranged on the second fluid control surface of the movable valve plate 122B. The above arrangement of 1220B determines that when the first channel 101B of the plane valve 10B of the water softener according to the second embodiment of the present utility model, the first part 1201B and the tenth channel 1010B of the first fluid control surface 1210B are respectively distributed at one equally divided position of the first fluid control surface 1210B, the second channel 102B and the fourth channel 104B of the plane valve 10B are respectively distributed at one equally divided position of the first fluid control surface 1210B, and the third channel 103B and the fifth channel 105B of the plane valve 10B are respectively distributed at one equally divided position of the first fluid control surface 1210B. The sixth channel 106B and the ninth channel 109B of the plane valve 10B are respectively distributed at one equally divided position of the second fluid control surface 1220B, the seventh channel 107B of the plane valve 10B is distributed at two equally divided positions of the second fluid control surface 1220B, and the eighth channel 108B of the plane valve 10B is distributed at two equally divided positions of the second fluid control surface 1220B, which can realize the sixth channel 106B, the seventh channel 107B, the ninth channel 109B, the sewage channel 1013B, the eighth channel 108B of the plane valve 10B and the seventh channel 107B of the plane valve 10B. The first channel 101B, the fourth channel 104B, the second channel 102B, the tenth channel 1010B, the second jet channel 1012B, the first jet channel 1011B, the third channel 103B and the fifth channel 105B are selectively connected at different working positions, and when the water softener of the utility model softens raw water, most of the area of ​​the first fluid control surface 1210B of the planar valve 10B of the water softener of the utility model (excluding the intervals between the channels distributed on the first fluid control surface 1210B and the central part 12101B that does not participate in the conduction, which is close to 6 / 10 of the area) participates in the flow of water.Since the raw water channel for providing raw water to the softening device 20 of the water softener of the utility model is composed of the sixth channel 106B and the first part 1201B of the first fluid control surface 1210B of the first channel 101B, as well as the ninth channel 109B and the tenth channel 1010B, wherein the first part 1201B of the first fluid control surface 1210B of the first channel 101B and the tenth channel 1010B occupy 2 equal parts of the first fluid control surface 1210B (close to 1 / 5 of the total area of ​​the first fluid control surface 1210B), the sixth channel 106B and the ninth channel 109B occupy 2 equal parts of the second fluid control surface 1220B (close to 1 / 5 of the total area of ​​the second fluid control surface 1220B), which is significantly higher than the ratio of the total area of ​​the first fluid control surface and the second fluid control surface of the plane valve occupied by the raw water channel for providing raw water in the existing plane valve for water softener. Correspondingly, the outlet channel (the second channel 102B and the third channel 103B) connected to the softening device 20 also occupies 2 equal parts of the first fluid control surface 1210B (close to 1 / 5 of the total area of ​​the first fluid control surface 1210B), and the soft water supply channel (the fourth channel 104B and the fifth channel 105B) connected to the water outlet 1104B also occupies 2 equal parts of the first fluid control surface 1210B (close to 1 / 5 of the total area of ​​the first fluid control surface 1210B). At this time, the movable valve plate 122B needs to have a contact with the The seventh channel 107B, which is mutually conductive with the second channel 102B and the fourth channel 104B, and the eighth channel 108B, which is mutually conductive with the third channel 103B and the fifth channel 105B, can realize the dual-channel water supply function. The seventh channel 107B also occupies 2 equal parts of the second fluid control surface 1220B (close to 1 / 5 of the total area of ​​the second fluid control surface 1220B), and the eighth channel 108B also occupies 2 equal parts of the second fluid control surface 1220B (close to 1 / 5 of the total area of ​​the second fluid control surface 1220B). Therefore, most of the areas (close to 6 / 10 of the area) of the first fluid control surface 1210B and the second fluid control surface 1220B of the plane valve 10B of the water softener of the utility model participate in the flow of water. It is understandable that only when the first fluid control surface 1210B and the second fluid control surface 1220B have most of their areas cooperate with each other to participate in the flow of water, can the water supply capacity with a large flow rate be achieved. In other words, the total cross-sectional area of ​​the inflow channel of the plane valve 10B of the water softener of the utility model supplying raw water to the softening device of the water softener and the total cross-sectional area of ​​the outflow channel of the obtained softened water can be increased as a proportion of the total flow control surface area of ​​the fixed valve plate and the moving valve plate, thereby significantly improving the softening water processing speed and softened water flow rate of the water softener of the utility model.That is to say, the first channel 101B, the fourth channel 104B, the second channel 102B, the tenth channel 1010B, the second jet channel 1012B, the first jet channel 1011B, the third channel 103B and the fifth channel 105B of the plane valve 10B of the water softener of the utility model are arranged on the first fluid control surface 1210B, the sixth channel 106B, the seventh channel 107B, the ninth channel 109B, the drain channel 1013B and the eighth channel 108B of the plane valve 10B are arranged on the second fluid control surface 1220B of the movable valve plate 122B, and the plane The equally divided positions of the first fluid control surface 1210B occupied by the first channel 101B, the fourth channel 104B, the second channel 102B, the tenth channel 1010B, the second jet channel 1012B, the first jet channel 1011B, the third channel 103B and the fifth channel 105B of the face valve 10B and the equally divided positions of the second fluid control surface 1220B of the movable valve plate 122B occupied by the sixth channel 106B, the seventh channel 107B, the ninth channel 109B, the sewage channel 1013B and the eighth channel 108B of the plane valve 10B determine its selective connection mode in different working positions.

[0286] As shown in the attached picture FIG. 27A to FIG. 28E , FIG. 36A to FIG. 37E , Fig.38E , Fig.38F and Fig.38JAs shown, the structural difference between the plane valve 10B and the plane valve 10C of the water softener according to the second embodiment of the utility model lies in that the drain channel 1013B of the plane valve 10B is different from the drain channel 1013C of the plane valve 10C, and the drain channel 1014C of the plane valve 10C participates in draining: the drain channel 1014C is arranged in the central part 12101C of the first fluid control surface 1210C, the drain channel 1013C is arranged in the seventh area 2007C and the central area 12201C of the second fluid control surface 1220C, and the drain channel 1013C is connected to the drain channel 1014C, and the drain channel 1013C is a conducting blind hole. Therefore, when the plane valve 10B and the plane valve 10C of the water softener according to the second embodiment of the utility model are in the corresponding working positions, the alignment method of the equal parts of the second fluid control surface 1220B of the movable valve plate 122B of the plane valve 10B and the equal parts of the first fluid control surface 1210B of the fixed valve plate 121B is the same as the alignment method of the equal parts of the second fluid control surface 1220C of the movable valve plate 122C of the plane valve 10C and the equal parts of the first fluid control surface 1210C of the fixed valve plate 121C. As described above, the difference in the functional realization of the plane valve 10B and the plane valve 10C of the water softener according to the second embodiment of the utility model is that the plane valve 10C of the water softener according to the second embodiment of the utility model discharges sewage through the sewage discharge channel 1013C, the discharge channel 1014C and the sewage discharge opening 1113C, and the discharge channel 1014C is arranged in the central part 12101C of the first fluid control surface 1210C, the sewage discharge channel 1013C is arranged in the seventh area 2007C and the central area 12201C of the second fluid control surface 1220C, the sewage discharge channel 1013C is connected to the discharge channel 1014C, and the sewage discharge opening 1113C is connected to the sewage discharge channel 1014C. The sewage channel 1013C is a conducting blind hole. Accordingly, when the plane valve 10C is in the regeneration working position, the third regeneration flow channel 10023C is formed by the third channel 103C, the sewage channel 1013C and the discharge channel 1014C being connected; when the plane valve 10C is in the backwash working position, the second backwash flow channel 10032C is formed by the tenth channel 1010C, the sewage channel 1013C and the discharge channel 1014C being connected; when the plane valve 10C is in the forward wash working position, the second forward wash flow channel 10052C is formed by the second channel 102C, the sewage channel 1013C and the discharge channel 1014C being connected.

[0287] In addition, according to the second embodiment of the utility model, the first channel 101B, the fourth channel 104B, the second channel 102B, the tenth channel 1010B, the second jet channel 1012B, the first jet channel 1011B, the third channel 103B and the fifth channel 105B of the plane valve 10B of the water softener are arranged on the first fluid control surface 1210B and the sixth channel 106B, the The seventh channel 107B, the ninth channel 109B, the drain channel 1013B and the eighth channel 108B are arranged on the second fluid control surface 1220B of the movable valve plate 122B, and the first channel 101C, the fourth channel 104C, the second channel 102C, the tenth channel 1010C, the second jet channel 1012C, the first jet channel 1010C, the second jet channel 1012C, the first jet channel 1010B, the second jet ... first jet channel 1010B, the second jet channel 1012C, the The above-mentioned arrangement of the sixth channel 106C, the seventh channel 107C, the ninth channel 109C, the drain channel 1013C and the eighth channel 108C of the plane valve 10C on the second fluid control surface 1220C of the movable valve plate 122C is basically the same (except that the drain channel 1013C extends from the seventh area 2007C of the second fluid control surface 1220C to the central area 12201C). Therefore, when the water softener of the present invention softens raw water, most of the area of ​​the first fluid control surface 1210C of the plane valve 10C of the water softener of the present invention (excluding the intervals between the channels distributed on the first fluid control surface 1210C and the central part 12101C that does not participate in conduction, which is close to 6 / 10 of the area) participates in the flow of water. Since the raw water channel for providing raw water to the softening device 20 of the water softener of the utility model is composed of the sixth channel 106C and the first part 1201C of the first fluid control surface 1210C of the first channel 101C, as well as the ninth channel 109C and the tenth channel 1010C, wherein the first part 1201C of the first fluid control surface 1210C of the first channel 101C and the tenth channel 1010C occupy 2 equal parts of the first fluid control surface 1210C (close to 1 / 5 of the total area of ​​the first fluid control surface 1210C), the sixth channel 106C and the ninth channel 109C occupy 2 equal parts of the second fluid control surface 1220C (close to 1 / 5 of the total area of ​​the second fluid control surface 1220C), which is significantly higher than the ratio of the total area of ​​the first fluid control surface and the second fluid control surface of the existing planar valve for water softeners occupied by the raw water channel for providing raw water.Correspondingly, the outlet channel (the second channel 102C and the third channel 103C) connected to the softening device 20 also occupies 2 equal parts of the first fluid control surface 1210C (close to 1 / 5 of the total area of ​​the first fluid control surface 1210C), and the soft water supply channel (the fourth channel 104C and the fifth channel 105C) connected to the water outlet 1104B also occupies 2 equal parts of the first fluid control surface 1210C (close to 1 / 5 of the total area of ​​the first fluid control surface 1210C). At this time, the movable valve plate 122C needs to have a contact with the The seventh channel 107C, which is mutually conductive with the second channel 102C and the fourth channel 104C, and the eighth channel 108C, which is mutually conductive with the third channel 103C and the fifth channel 105C, can realize the dual-channel water supply function. The seventh channel 107C also occupies 2 equal parts of the second fluid control surface 1220C (close to 1 / 5 of the total area of ​​the second fluid control surface 1220C), and the eighth channel 108C also occupies 2 equal parts of the second fluid control surface 1220C (close to 1 / 5 of the total area of ​​the second fluid control surface 1220C). Therefore, most of the areas (close to 6 / 10 of the area) of the first fluid control surface 1210C and the second fluid control surface 1220C of the plane valve 10C of the water softener of the utility model participate in the flow of water. It is understandable that only when the first fluid control surface 1210C and the second fluid control surface 1220C have most of their areas cooperate with each other to participate in the flow of water, can the water supply capacity with a large flow rate be achieved. In other words, the total cross-sectional area of ​​the inflow channel of the plane valve 10C of the water softener of the utility model supplying raw water to the softening device of the water softener and the total cross-sectional area of ​​the outflow channel of the obtained softened water can be increased as a proportion of the total flow control surface area of ​​the fixed valve plate and the moving valve plate, thereby significantly improving the softening water processing speed and softened water flow rate of the water softener of the utility model.
