Description

Technical Field

[0001] This utility model relates to a water softener, and more particularly to a flat valve for a water softener. Background Technology

[0002] A water softener softens water with high hardness, reducing its hardness. Water softeners typically use a planar valve to control the water flow. Generally, the planar valve in a water softener has a fixed valve plate and a movable valve plate. The planar valve selectively connects the through-holes of the fixed and movable valve plates to create different water flow channels and control the water flow. The planar valve in a water softener usually includes an ejector connected to the channel of the fixed valve plate in the valve core. This ejector connects to the brine tank to achieve functions such as regenerating the softening filter cartridge.

[0003] Many water softeners, especially industrial water softeners, use a planar valve structure. The valve stem presses against a moving valve plate, which in turn presses against a fixed valve plate. The fixed valve plate rests at the bottom of the valve chamber (bottom of the valve body). There is a hard seal between the moving and fixed valve plates, so no sealing element is used; instead, the surfaces directly seal. The seal between the fixed valve plate and the bottom of the valve chamber typically uses a sealing gasket. To achieve high flow rates, industrial water softeners often have a larger diameter planar valve. During operation, the planar valve is subjected to water pressure, causing deformation, especially in the vertical direction (axial deformation of the valve stem's central rotation axis). (Deformation in the vertical direction) At this time, the seal of the fixed valve plate and the sealing gasket structure at the bottom of the valve cavity will weaken or fail, and the seal between the channel in the fixed valve plate and the various openings at the bottom of the valve cavity will weaken or fail, causing water in the channel in the fixed valve plate or water in the valve cavity to leak into the various openings at the bottom of the valve cavity. This water leakage is divided into internal leakage and external leakage. Internal leakage is crossflow within the water system, affecting the filtration or softening effect, but does not cause water waste or flood hazards. External leakage is mainly due to the possibility of water leakage in the channel (or opening) at the bottom of the valve cavity that connects to the ejector. More specifically, generally, there are two reasons for water leakage in the channel of the plane valve of the water softener that connects to the ejector: one reason is that the wear of the fixed valve plate or moving valve plate of the plane valve causes the seal between the fluid control surface of the fixed valve plate and the fluid control surface of the moving valve plate to be damaged, causing water to flow from other channels into the jet water path of the plane valve of the water softener that connects to the ejector. This type of water leakage can be avoided by strengthening the seal between the fluid control surfaces of the stationary and moving valve plates of the water softener's planar valve. Another reason is that when the planar valve of the water softener is subjected to water pressure, the valve body deforms vertically, disrupting the good seal between the stationary valve plate and the valve body. Water from other channels will flow through the gap between the stationary valve plate and the valve body into the channel connecting the valve body to the ejector, and then through the ejector into the brine tank or brine container. In particular, the valve body of the planar valve is often made of plastic and has an asymmetrical internal structure. Due to the uneven shrinkage of the plastic material during cooling, the surface of the valve body that seals with the stationary valve plate is often uneven. This makes it more difficult to achieve a uniform seal between the valve body and the stationary valve plate when the planar valve of the water softener is subjected to water pressure, making leakage more likely. This type of leakage mostly occurs in the softening stage of the water softener (which is the stage where the raw water is softened, and where the water softener's flat valve is subjected to high water pressure). Prolonged leakage from the flat valve causes excessive water to flow into the brine tank, leading to a gradual rise in the water level. This results in excess dissolved brine being continuously discharged through the brine tank overflow, wasting regeneration salt and water.In water softeners with independent float-type brine valves, the continuous water supply caused by prolonged leakage from the ejector of the flat valve puts continuous water pressure on the float-type brine valve (which typically uses a soft seal made of rubber parts, and since it is placed in a brine tank containing a large number of salt crystal particles, these particles significantly affect the reliability of the soft seal on the rubber parts). This leads to a shortened lifespan of the float-type brine valve and leakage. The leaked water enters the brine tank, eventually causing the water level to gradually rise, resulting in the continuous discharge of brine through the overflow outlet, wasting regeneration salt and water.

[0004] Most existing industrial water softeners use a separate, electrically controlled external valve (not a float-type brine valve, typically an electrically controlled ceramic ball valve or electrically controlled ceramic plane valve) installed at the brine inlet of the injector to prevent leaks from flowing into the brine tank or brine solution tank. However, this separate electrically controlled external valve not only increases costs but also leads to a higher failure rate for the entire water softener. Furthermore, the separate electrically controlled external valve at the injector's brine inlet requires additional control to manage its opening and closing during different operating states (generally, it needs to be closed during softening and opened during regeneration and replenishment), increasing the overall control complexity of the water softener. Utility Model Content

[0005] The main advantage of this invention is that it provides a planar valve for a water softener, which can effectively prevent water from leaking into the ejector when the valve body of the planar valve for a water softener is under pressure.

[0006] Another advantage of this utility model is that the planar valve used in water softeners does not require changes to the number of holes, the arrangement of the holes, or the communication relationship between the fixed valve plate and the moving valve plate of the existing planar valve used in water softeners. The purpose of this utility model can be achieved simply by improving the existing planar valve used in water softeners.

The plurality of first water flow channels 100D are respectively connected to the plurality of water flow openings 1100D of the valve body 11D. The first jet channel 1011D is connected to the first jet opening 1111D of the valve body 11D. The second jet channel 1012D is connected to the second jet opening 1112D of the valve body 11D. The connecting portion 112... D forms multiple through holes 1120D, a first jet through hole 1121D, and a second jet through hole 1122D. Each of the multiple through holes 1120D is connected to a corresponding multiple first water flow channel 100D and multiple water flow openings 1100D. The first jet through hole 1121D is connected to the first jet channel 1011D and the first jet opening 1111D.

In other words, the first jet orifice 1121D and the first jet channel 1011D are connected via the first conduit 131D, and the second jet orifice 1122D and the second jet channel 1012D are connected via the second conduit 132D.

[0058] As shown in the attached image. Figures 2A to 6CAs shown, by way of example, in the planar valve 10D for a water softener according to an embodiment of the present invention, the first guide pipe 131D forms a first guide end 1311D and a first connection end 1312D, and the second guide pipe 132D forms a second guide end 1321D and a second connection end 1322D.

Accordingly, the first conducting end 1311D and the first connecting end 1312D of the first conducting tube 131D are respectively water-sealed within the first jet channel 1011D and the first jet orifice 1121D, thereby connecting the first conducting channel 1310D of the first conducting tube 131D to the first jet channel 1011D and the first jet orifice 1121D, respectively; the second conducting end 1321D and the second connecting end 1322D of the second conducting tube 132D are respectively water-sealed within the second jet channel 1012D and the second jet orifice 1122D, thereby connecting the second conducting channel 1320D of the second conducting tube 132D to the second jet channel 1012D and the second jet orifice 1122D, respectively. Correspondingly, even when the water softener softens the raw water, the flat valve 10D used in the water softener is subjected to a large water pressure, causing its valve body 11D to deform in the vertical direction and the longitudinal seal (or horizontal seal) between the fixed valve plate 121D and the guide portion 112D of the flat valve 10D of the water softener to be damaged. However, since the first guide end 1311D and the first connection end 1312D of the first guide pipe 131D are respectively water-sealed in the first jet channel 1011D and the first jet orifice 1121D, the second guide pipe 132 The second conductive end 1321D and the second connecting end 1322D of D are respectively water-sealed in the second jet channel 1012D and the second jet orifice 1122D. Water from other water channels (water between the conductive part 112D of the valve body 11D and the fixed valve plate 121D) cannot leak into the first jet channel 1011D, the first conductive pipe 131D, the first jet orifice 1121D, the second jet channel 1012D, the second conductive pipe 132D, and the second jet orifice 1122D.

[0059] As shown in the attached image. Figures 2A to 6CAs shown, by way of example, in the planar valve 10D for a water softener according to an embodiment of the present invention, the first conducting end 1311D of the first conducting pipe 131D is detachably disposed in the first jet channel 1011D, and the second conducting end 1321D of the second conducting pipe 132D is detachably disposed in the second jet channel 1012D.

Accordingly, the sealing between the first conducting end 1311D of the first conducting tube 131D and the first jet channel 1011D can be achieved by a sealing mechanism disposed between the first conducting end 1311D of the first conducting tube 131D and the first jet channel 1011D. Preferably, the sealing between the first conducting end 1311D of the first conducting tube 131D and the first jet channel 1011D can be achieved by a sealing mechanism disposed between the outer wall of the first conducting end 1311D of the first conducting tube 131D and the inner wall of the first jet channel 1011D. Currently, the seal between the second conducting end 1321D of the second conducting tube 132D and the second jet channel 1012D can be achieved by a sealing mechanism disposed between the second conducting end 1321D of the second conducting tube 132D and the second jet channel 1012D. Preferably, the seal between the second conducting end 1321D of the second conducting tube 132D and the second jet channel 1012D can be achieved by a sealing mechanism disposed between the outer wall of the second conducting end 1321D of the second conducting tube 132D and the inner wall of the second jet channel 1012D. Preferably, the seal between the first connecting end 1312D of the first conductive tube 131D and the conductive part 112D is achieved by integrally forming the first connecting end 1312D of the first conductive tube 131D with the inner wall of the first ejection orifice 1121D, and the seal between the second connecting end 1322D of the second conductive tube 132D and the conductive part 112D is achieved by integrally forming the second connecting end 1322D of the second conductive tube 132D with the inner wall of the second ejection orifice 1122D.

[0060] Existing planar valves for water softeners, made of materials such as plastic, deform (stretch) vertically under high water pressure, causing damage to the longitudinal (or horizontal) seal between the fixed valve plate and the guide section, resulting in leakage. This invention, using a planar valve 10D for water softeners, features an innovative and unique side-sealing structure formed by the fixed valve plate 121D, the guide section 112D, the first guide tube 131D, and the second guide tube 132D, solving the aforementioned leakage problem. Traditional hard-seal planar valves often require grinding of the fixed valve plate before use, typically involving double-sided grinding. The resulting seal between the fixed valve plate and the valve body is usually achieved using a planar pressure seal with a sealing gasket.

[0061] Accordingly, the planar valve 10D for water softeners of this invention solves the water leakage problem of the jet water path of the existing planar valve 10D for water softeners by using its fixed valve plate 121D and the guide part 112D to achieve a side seal between them and the first guide pipe 131D and the second guide pipe 132D.

The tube body 1323D extends outward, and the fixed valve plate 121D forms a first mounting hole 12110D and a second mounting hole 12120D, wherein the first mounting hole 12110D is disposed around the first jet channel 1011D, and the second mounting hole 12120D is disposed around the second jet channel 1012D, wherein the first holding portion 1314D of the first guiding tube 131D is adapted to be disposed within the first mounting hole 12110D; and the second holding portion 1324D of the second guiding tube 132D is adapted to be disposed within the second mounting hole 12120D.

[0063] As shown in the attached image. Figures 2B to 6CAs shown, exemplarily, the planar valve 10D for a water softener according to an embodiment of the present invention further includes at least one first sealing ring 141D and at least one second sealing ring 142D, wherein the at least one first sealing ring 141D is disposed within the first mounting hole 12110D, the at least one second sealing ring 142D is disposed within the second mounting hole 12120D, and the at least one first sealing ring 141D is watertightly held between the fixed valve plate 121D and the first conductive tube body 1313D, and the at least one second sealing ring 142D is watertightly held between the fixed valve plate 121D and the second conductive tube body 1323D. It can be understood that the at least one first sealing ring 141D is used to achieve a water seal between the fixed valve plate 121D and the first conductive tube 131D, and the at least one second sealing ring 142D is used to achieve a water seal between the fixed valve plate 121D and the second conductive tube 132D. It is worth noting that the first retaining portion 1314D helps to watertightly retain the at least one first sealing ring 141D within the first mounting hole 12110D, and the second retaining portion 1324D helps to watertightly retain the at least one second sealing ring 142D within the second mounting hole 12120D. Accordingly, the at least one first sealing ring 141D and the first retaining portion 1314D, and the at least one second sealing ring 142D and the second retaining portion 1324D, are used to ensure a lateral water seal between the fixed valve plate 121D and the conducting portion 112D, so that even if the longitudinal seal (or horizontal seal) between the fixed valve plate 121D and the conducting portion 112D of the planar valve 10D of the present invention for a water softener is broken, water flow cannot leak from the jet water path.

[0064] As shown in the attached image. Figures 4A to 6CAs shown, exemplarily, the fixed valve plate 121D of the planar valve 10D for a water softener according to an embodiment of the present invention forms a first sealing sidewall 1211D and a second sealing sidewall 1212D, wherein the first sealing sidewall 1211D surrounds the first mounting hole 12110D, the second sealing sidewall 1212D surrounds the second mounting hole 12120D, and the first retaining portion 1314D of the first connecting pipe 131D is laterally facing the first sealing sidewall 1211D, and the second retaining portion 1324D of the second connecting pipe 132D is laterally facing the second sealing sidewall 1212D, so that the at least one first sealing ring 141D and the at least one second sealing ring 142D is positioned higher than the bottom of the first sealing sidewall 1211D and the second sealing sidewall 1212D, respectively. This ensures that when leaked water (or water from other water passages of the valve body) flows from the bottom of the first sealing sidewall 1211D to the first guide pipe 131D and from the bottom of the second sealing sidewall 1212D to the second guide pipe 132D, the water pressure of the leaked water (or water from other water passages of the valve body) will first act on the first retaining portion 1314D of the first guide pipe 131D and the second retaining portion 1324D of the second guide pipe 132D, and then act on the at least one first sealing ring 141D and the at least one second sealing ring 142D, respectively. It is worth noting that if the at least one first sealing ring 141D and the at least one second sealing ring 142D are respectively lower than the bottom of the first sealing sidewall 1211D and the second sealing sidewall 1212D in terms of height, leaked water can easily leak from the position between the at least one first sealing ring 141D and the at least one second sealing ring 142D and the fixed valve plate 121D. In other words, the first sealing sidewall 1211D of the fixed valve plate 121D, the first retaining portion 1314D of the first guide tube 131D, and the at least one first sealing ring 141D form a reinforced lateral sealing structure, and the second sealing sidewall 1212D of the fixed valve plate 121D, the second retaining portion 1324D of the second guide tube 132D, and the at least one second sealing ring 142D form a reinforced lateral sealing structure to prevent water leakage through the jet water path.

[0065] As shown in the attached image. Figures 4A to 6CAs shown, by way of example, the fixed valve plate 121D of the planar valve 10D for a water softener according to an embodiment of the present invention forms a first sealing step 1213D and a second sealing step 1214D, wherein the first sealing step 1213D extends inward from the first sealing sidewall 1211D, the second sealing step 1214D extends inward from the second sealing sidewall 1212D, and the first sealing step 1213D is disposed opposite to the first retaining portion 1314D of the first connecting pipe 131D, the second sealing step 1214D is disposed opposite to the second retaining portion 1324D of the second connecting pipe 132D, wherein at least one first sealing ring 141D is disposed between the first sealing step 1213D and the first retaining portion 1314D of the first connecting pipe 131D, and at least one second sealing ring 142D is disposed between the second sealing step 1214D and the second retaining portion 1324D of the second connecting pipe 132D. Accordingly, when leaked water (or water from other water passages of the valve body) flows from the bottom of the first sealing sidewall 1211D to the first connecting pipe 131D and from the bottom of the second sealing sidewall 1212D to the second connecting pipe 132D, the water pressure of the leaked water (or water from other water passages of the valve body) will first act on the first retaining portion 1314D of the first connecting pipe 131D and the second retaining portion 1324D of the second connecting pipe 132D, and then act on the at least one first sealing ring 141D and the at least one second sealing ring 142D respectively. If the water pressure of the leaked water (or water from other water passages of the valve body) is large enough that the at least one first sealing ring 141D and the at least one second sealing ring 142D are driven to move, the at least one first sealing ring 141D and the at least one second sealing ring 142D will be pushed and pressed against the first sealing step 1213D and the second sealing step 1214D respectively. In other words, the first sealing step 1213D of the fixed valve plate 121D, the first retaining portion 1314D of the first conductive tube 131D, and the at least one first sealing ring 141D form a reinforced lateral sealing structure, and the second sealing step 1214D of the fixed valve plate 121D, the second retaining portion 1324D of the second conductive tube 132D, and the at least one second sealing ring 142D form a reinforced lateral sealing structure to prevent water leakage through the jet water path.

Figures 2B to 6CAs shown, exemplarily, the fixed valve plate 121D of the planar valve 10D for a water softener according to an embodiment of the present invention further includes a sealing gasket 1217D, wherein the sealing gasket 1217D is disposed between the valve core 12D and the valve body 11D. Further, the sealing gasket 1217D is disposed between the fixed valve plate 121D and the conductive portion 112D.

[0067] As shown in the attached image. Figures 1 to 3F As shown, exemplarily, the planar valve 10D for a water softener according to an embodiment of the present invention further includes an ejector 18D, wherein the ejector 18D has an outlet 182D communicating with the first ejection opening 1111D of the valve body 11D, an inlet 183D communicating with the second ejection opening 1112D of the valve body 11D, and a brine inlet 181D, wherein the brine inlet 181D is connected to the outlet 182D and the inlet 183D respectively. When water, such as tap water, flows from the outlet 182D of the ejector 18D to the inlet 183D of the ejector 18D, a negative pressure occurs at the brine inlet 181D of the ejector 18D, thereby allowing the regeneration solution to flow from the brine inlet 181D of the ejector 18D to the inlet 183D of the ejector 18D. Accordingly, the salt intake port 181D of the ejector 18D is connected to the ejection outlet 182D and the ejection inlet 183D of the ejector 18D, respectively.

[0068] As shown in the attached image. Figures 1 to 3F As shown, exemplarily, the planar valve 10D for a water softener according to an embodiment of the present invention further includes a brine suction pipe 184 and a brine tank 31, wherein one end of the brine suction pipe 184 is connected to the brine suction port 181D, and the other end of the brine suction pipe 184 is connected to the brine tank 31, so that brine can be supplied to the brine suction port 181D through the brine suction pipe 184, or water can flow out sequentially from the first jet opening 1111D, the jet outlet 182D and the brine suction port 181D (or water can flow out sequentially from the second jet opening 1112D, the jet inlet 183D and the brine suction port 181D) and flow through the brine suction pipe 184 to the brine tank 31 to replenish the brine tank 31.

[0069] It is worth noting that the fixed valve plate 121D of the planar valve 10D can be detachably disposed on the inner wall 111D of the valve body 11D, or it can be integrally formed with the inner wall 111D of the valve body 11D of the planar valve 10D. Those skilled in the art will understand that when the fixed valve plate 121D is detachably disposed within the valve body 11D, a fixing mechanism maintains synchronization between the fixed valve plate 121D and the valve body 11D. For example, as shown in the attached figures... Figures 3B to 4B As shown, the fixed valve plate 121D has a braking element 123D protruding outward from the edge of the fixed valve plate 121D, and the inner wall 111D of the valve body 11D has a braking portion 1110D. The braking element 123D of the fixed valve plate 121D is configured to engage with the braking portion 1110D of the inner wall 111D of the valve body 11D to ensure synchronization between the fixed valve plate 121D and the valve body 11D (or to prevent relative rotation) and to ensure that the various channels provided in the fixed valve plate 121D communicate with the corresponding openings provided in the valve body 11D. It can be understood that when the fixed valve plate 121D is detachably disposed within the valve body 11D, the fixed valve plate 121D (or detachably disposed in the conductive portion 112D) can be manufactured separately. In other words, the fixed valve plate 121D can be made of wear-resistant plastic or ceramic material, thereby improving the service life of the fixed valve plate 121D (or the entire flat valve 10D). Preferably, the first fluid control surface 1210D of the fixed valve plate 121D is smoothed to reduce its roughness.

Accordingly, the seal between the first conducting end 1311H of the first conducting tube 131H and the first jet channel 1011H can be achieved by integrally forming the first conducting end 1311H of the first conducting tube 131H and the inner wall of the first jet channel 1011H. Similarly, the seal between the second conducting end 1321H of the second conducting tube 132H and the second jet channel 1012H can be achieved by integrally forming the second conducting end 1321H of the second conducting tube 132H and the inner wall of the second jet channel 1012H. The seal between the first connecting end 1312H of the first conducting tube 131H and the conducting portion 112H can be achieved by a sealing mechanism disposed between the first connecting end 1312H of the first conducting tube 131H and the first jet orifice 1121H. Preferably, the... The sealing between the first connecting end 1312H of the first conductive tube 131H and the conductive part 112H can be achieved by a sealing mechanism disposed between the outer wall of the first connecting end 1312H of the first conductive tube 131H and the inner wall of the first ejection orifice 1121H. The sealing between the second connecting end 1322H of the second conductive tube 132H and the conductive part 112H can be achieved by a sealing mechanism disposed between the second connecting end 1322H of the second conductive tube 132H and the second ejection orifice 1122H. Preferably, the sealing between the second connecting end 1322H of the second conductive tube 132H and the conductive part 112H can be achieved by a sealing mechanism disposed between the outer wall of the second connecting end 1322H of the second conductive tube 132H and the inner wall of the second ejection orifice 1122H.

The second water flow channels 200F are respectively disposed on the moving valve plate 122F and extend from the second fluid control surface 1220F of the moving valve plate 122F. The plurality of first water flow channels 100F are respectively connected to the plurality of water flow openings 1100F of the valve body 11F. The first jet channel 1011F is connected to the first jet opening 1111F of the valve body 11F. The second jet channel 1012F is connected to the second jet opening 1112F of the valve body 11F. The connecting portion 112... F forms a plurality of through holes 1120F, a first jet through hole 1121F, and a second jet through hole 1122F, wherein each of the plurality of through holes 1120F is respectively connected to the corresponding plurality of first water flow channels 100F and the plurality of water flow openings 1100F, the first jet through hole 1121F is respectively connected to the first jet channel 1011F and the first jet opening 1111F, and the second jet through hole 1122F is respectively connected to the second jet channel 1012F and the second jet opening 1111F. The first and second conductive pipes 131F and 132F are respectively water-sealed between the fixed valve plate 121F and the conductive portion 112F of the valve body 11F. The first conductive channel 1310F of the first conductive pipe 131F is connected to the first jet orifice 1121F and the first jet channel 1011F, respectively. The second conductive channel 1320F of the second conductive pipe 132F is connected to the second jet orifice 1122F and the second jet channel 1012F, respectively. In other words, the first jet orifice 1121F and the first jet channel 1011F are connected through the first conductive pipe 131F, and the second jet orifice 1122F and the second jet channel 1012F are connected through the second conductive pipe 132F.

[0074] As shown in the attached image. Figures 8 to 13CAs shown, by way of example, in the planar valve 10F of a water softener according to an embodiment of the present invention, the first conductive pipe 131F forms a first conductive end 1311F and a first connecting end 1312F, and the second conductive pipe 132F forms a second conductive end 1321F and a second connecting end 1322F. The first conductive end 1311F and the first connecting end 1312F of the first conductive pipe 131F are respectively water-sealed in the first jet channel 1011F and the first jet orifice 1121F, and the second conductive end 1321F and the second connecting end 1322F of the second conductive pipe 132F are respectively water-sealed in the second jet channel 1012F and the second jet orifice 1122F. Accordingly, the first conducting end 1311F and the first connecting end 1312F of the first conducting tube 131F are respectively water-sealed within the first jet channel 1011F and the first jet orifice 1121F, thereby connecting the first conducting channel 1310F of the first conducting tube 131F to the first jet channel 1011F and the first jet orifice 1121F, respectively; the second conducting end 1321F and the second connecting end 1322F of the second conducting tube 132F are respectively water-sealed within the second jet channel 1012F and the second jet orifice 1122F, thereby connecting the second conducting channel 1320F of the second conducting tube 132F to the second jet channel 1012F and the second jet orifice 1122F, respectively. Correspondingly, even when the water softener softens the raw water, the flat valve 10F of the water softener is subjected to a large water pressure, causing its valve body 11F to deform in the vertical direction and the longitudinal seal (or horizontal seal) between the fixed valve plate 121F and the guide portion 112F of the flat valve 10F of the water softener to be damaged. However, since the first guide end 1311F and the first connection end 1312F of the first guide pipe 131F are respectively water-sealed in the first jet channel 1011F and the first jet orifice 1121F, the second guide pipe 132... The second conductive end 1321F and the second connecting end 1322F of F are respectively water-sealed in the second jet channel 1012F and the second jet orifice 1122F. Water flow from other water flow channels (water flow between the conductive part 112F of the valve body 11F and the fixed valve plate 121F) cannot leak into the first jet channel 1011F, the second jet channel 1012F, the first conductive pipe 131F, the second conductive pipe 132F, the first jet orifice 1121F and the second jet orifice 1122F.

[0075] As shown in the attached image. Figures 8 to 13CAs shown, by way of example, in the embodiment of the present invention, the first conducting end 1311F and the first connecting end 1312F of the first conducting pipe 131F of the planar valve 10F for a water softener are respectively detachably disposed in the first jet channel 1011F and the first jet orifice 1121F, and the second conducting end 1321F and the second connecting end 1322F of the second conducting pipe 132F are respectively detachably disposed in the second jet channel 1012F and the second jet orifice 1122F.

The sealing mechanism between the inner walls of F is achieved; the sealing between the second conducting end 1321F of the second conducting tube 132F and the second jet channel 1012F can be achieved by a sealing mechanism disposed between the second conducting end 1321F and the second jet channel 1012F. Preferably, the sealing between the second conducting end 1321F of the second conducting tube 132F and the second jet channel 1012F can be achieved by a sealing mechanism disposed between the outer wall of the second conducting end 1321F and the inner wall of the second jet channel 1012F; .... The sealing between the second connecting end 1322F of the conduit 132F and the second jetting hole 1122F can be achieved by a sealing mechanism disposed between the second connecting end 1322F and the second jetting hole 1122F of the second conduit 132F.

The portions of F and the first jet passage 1121F have sufficient length. The second conducting end 1321F and the second connecting end 1322F of the second guiding pipe 132F are respectively water-sealed within the portions of the second jet channel 1012F and the second jet passage 1122F, having sufficient length to prevent the first guiding pipe 131F from detaching from the first jet channel 1011F or the first jet passage 1121F when the valve body 11F deforms (stretches), and to prevent the second guiding pipe 132F from detaching from the second jet channel 1012F or the second jet passage 1122F. Accordingly, the communication between the jet channel of the fixed valve plate 121F and the jet passage of the guiding part 112F in the planar valve 10F of the water softener of this utility model is sealed by the side of the first guiding pipe 131F and the second guiding pipe 132F, solving the water leakage problem of the jet water path of the existing planar valve 10F for water softeners.

Figures 10A to 13CAs shown, according to an embodiment of the present invention, the first guide pipe 131F of the planar valve 10F for a water softener has a first guide pipe body 1313F and a first retaining portion 1314F; the second guide pipe 132F has a second guide pipe body 1323F and a second retaining portion 1324F; the fixed valve plate 121F forms a first mounting space 12101F and a second mounting space 12102F; the guide portion 112F forms a third mounting space 12103F and a fourth mounting space 12104F; wherein the first retaining portion 1314F is disposed in the middle portion of the first guide pipe body 1313F and extends outward from the first guide pipe body 1313F; the second retaining portion 1324F is disposed in the middle portion of the second guide pipe body 1323F and extends outward from the second guide pipe body 1323F; and the first mounting space 12101F is provided with... A second mounting space 12102F is disposed around the first jet channel 1011F, a third mounting space 12103F is disposed around the first jet orifice 1121F, and a fourth mounting space 12104F is disposed around the second jet orifice 1122F. The first mounting space 12101F and the third mounting space 12103F are disposed correspondingly to form a first mounting hole 12110F, and the second mounting space 12102F and the fourth mounting space 12104F are disposed correspondingly to form a second mounting hole 12120F. The first holding portion 1314F of the first conductive tube 131F is adapted to be disposed within the first mounting hole 12110F, and the second holding portion 1324F of the second conductive tube 132F is adapted to be disposed within the second mounting hole 12120F. In other words, the first mounting hole 12110F of the fixed valve plate 121F is partially formed in the fixed valve plate 121F and partially formed in the conductive portion 112F, and the second mounting hole 12120F of the fixed valve plate 121F is partially formed in the fixed valve plate 121F and partially formed in the conductive portion 112F, so as to ensure that the first conductive end 1311F and the first connecting end 1312F of the first conductive tube 131F are respectively disposed in the first jet channel 1011F and the first jet orifice 1121F, and the second conductive end 1321F and the second connecting end 1322F of the second conductive tube 132F are respectively disposed in the second jet channel 1012F and the second jet orifice 1122F.

Figures 8 to 13CAs shown, the planar valve 10F for a water softener according to an embodiment of the present invention further includes two first sealing rings 141F and two second sealing rings 142F. The two first sealing rings 141F are respectively disposed in the first mounting hole 12110F and located on opposite sides of the first retaining portion 1314F. The two second sealing rings 142F are respectively disposed in the second mounting hole 12120F and located on opposite sides of the second retaining portion 1324F. Specifically, the two first sealing rings 141F are respectively located within the first mounting space 12101F and the third mounting space 12103F, and the two second sealing rings 142F are respectively located within the second mounting space 12102F and the fourth mounting space 12104F. It can be understood that the two first sealing rings 141F are used to achieve water sealing between the fixed valve plate 121F and the first conductive pipe 131F and the conductive part 112F and the first conductive pipe 131F, respectively, and the two second sealing rings 142F are used to achieve water sealing between the fixed valve plate 121F and the second conductive pipe 132F and the conductive part 112F and the second conductive pipe 132F, respectively. Accordingly, the two first sealing rings 141F and the first retaining portion 1314F, and the two second sealing rings 142F and the second retaining portion 1324F are used to ensure lateral water seals between the fixed valve plate 121F and the first and second connecting pipes 131F and 132F, and between the connecting portion 112F and the first and second connecting pipes 131F and 132F, so that even if the longitudinal seal (or horizontal seal) between the fixed valve plate 121F and the connecting portion 112F of the planar valve 10F of the water softener of this invention is damaged, water flow cannot leak from the jet water path. It can be understood that the first retaining portion 1314F helps to water-tightly retain the two first sealing rings 141F within the first mounting hole 12110F, and the second retaining portion 1324F helps to water-tightly retain the two second sealing rings 142F within the second mounting hole 12120F.

[0079] As shown in the attached image. Figures 10A to 13CAs shown, in an embodiment of the present invention, the fixed valve plate 121F of the planar valve 10F for a water softener forms a first sealing sidewall 1211F and a second sealing sidewall 1212F, and the guide portion 112F forms a third sealing sidewall 1213F and a fourth sealing sidewall 1214F. The first sealing sidewall 1211F surrounds the first mounting space 12101F, the second sealing sidewall 1212F surrounds the second mounting space 12102F, the third sealing sidewall 1213F surrounds the third mounting space 12103F, and the fourth sealing sidewall 1214F surrounds the fourth mounting space 12104F. The first sealing sidewall 1211F and the third sealing sidewall 1213F are respectively partially aligned with the first guide pipe 131F. The first retaining portion 1314F, the second sealing sidewall 1212F, and the fourth sealing sidewall 1214F are respectively partially aligned with the second retaining portion 1324F of the second conduit 132F. This ensures that when leaked water flows from the gap between the first sealing sidewall 1211F and the third sealing sidewall 1213F to the first conduit 131F or from the gap between the second sealing sidewall 1212F and the fourth sealing sidewall 1214F to the second conduit 132F, the water pressure of the leaked water will first act on the first retaining portion 1314F of the first conduit 131F and the second retaining portion 1324F of the second conduit 132F, and then act on the two first sealing rings 141F and the two second sealing rings 142F, respectively. In other words, the first sealing sidewall 1211F, the first retaining portion 1314F of the first conductive tube 131F, and the first sealing ring 141F form a reinforced lateral sealing structure; the second sealing sidewall 1212F, the second retaining portion 1324F of the second conductive tube 132F, and the second sealing ring 142F form a reinforced lateral sealing structure; the third sealing sidewall 1213F, the first retaining portion 1314F of the first conductive tube 131F, and the first sealing ring 141F form a reinforced lateral sealing structure; and the fourth sealing sidewall 1214F, the second retaining portion 1324F of the second conductive tube 132F, and the second sealing ring 142F form a reinforced lateral sealing structure to prevent water leakage through the jet water path.

[0080] As shown in the attached image. Figures 10A to 13CAs shown, exemplarily, in the planar valve 10F of a water softener according to an embodiment of the present invention, the fixed valve plate 121F forms a first sealing step 12131F and a second sealing step 12132F, and the conducting portion 112F forms a third sealing step 12133F and a fourth sealing step 12134F. The first sealing step 12131F extends inward from the first sealing sidewall 1211F, the second sealing step 12132F extends inward from the second sealing sidewall 1212F, and the third sealing step 12133F... A sealing step 1213F extends inward from the third sealing sidewall 1213F, and a fourth sealing step 12134F extends inward from the fourth sealing sidewall 1214F. The first sealing step 12131F and the third sealing step 12133F are respectively positioned opposite two opposite sides of the first retaining portion 1314F of the first conductive tube 131F. The second sealing step 12132F and the fourth sealing step 12134F are respectively positioned opposite two opposite sides of the second retaining portion 1324F of the second conductive tube 132F. Further, a first mounting hole 12110F is formed between the first sealing step 12131F and the third sealing step 12133F, and a second mounting hole 12120F is formed between the second sealing step 12132F and the fourth sealing step 12134F. Accordingly, the two first sealing rings 141F are respectively disposed between the first sealing step 12131F and the third sealing step 12133F and the first retaining portion 1314F of the first conductive tube 131F, and the two second sealing rings 142F are respectively disposed between the second sealing step 12132F and the fourth sealing step 12134F and the second retaining portion 1324F of the second conductive tube 132F. Accordingly, when leaked water flows from the gap between the first sealing sidewall 1211F and the third sealing sidewall 1213F to the first conduit 131F and from the gap between the second sealing sidewall 1212F and the fourth sealing sidewall 1214F to the second conduit 132F, the water pressure of the leaked water will first act on the first retaining part 1314F of the first conduit 131F and the second retaining part 1324F of the second conduit 132F, and then act on the two first sealing rings 141F and the two second sealing rings 142F respectively. If the water pressure of the leaked water is high enough that the two first sealing rings 141F and the two second sealing rings 142F are driven to move, the two first sealing rings 141F will be pushed and pressed against the first sealing step 12131F and the third sealing step 12133F respectively, and the two second sealing rings 142F will be pushed and pressed against the second sealing step 12132F and the fourth sealing step 12134F respectively.In other words, the first sealing step 12131F, the third sealing step 12133F, the first retaining portion 1314F of the first conduit 131F, and the two first sealing rings 141F form a reinforced lateral sealing structure to prevent water leakage through the first jet channel 1011F and the first jet orifice 1121F; the second sealing step 12132F, the fourth sealing step 12134F, the second retaining portion 1324F of the second conduit 132F, and the two second sealing rings 142F form a reinforced lateral sealing structure to prevent water leakage through the second jet channel 1012F and the second jet orifice 1122F. Accordingly, the first retaining portion 1314F helps to watertightly retain the two first sealing rings 141F within the first mounting hole 12110F, and the second retaining portion 1324F helps to watertightly retain the two second sealing rings 142F within the second mounting hole 12120F to ensure lateral sealing.

[0081] As shown in the attached image. Figures 10A to 13C As shown, in an embodiment of the present invention, the first guide pipe 131F of the planar valve 10F for a water softener is suspended by the first holding part 1314F, and the second guide pipe 132F is suspended by the second holding part 1324F.

[0082] As shown in the attached image. Figures 10A to 13C As shown, the first jet channel 1011F and the first jet orifice 1121F are respectively adapted to the first conducting end 1311F and the first connecting end 1312F of the first conducting tube 131F, so that the first conducting tube 131F can be held suspended by the first holding part 1314F; the second jet channel 1012F and the second jet orifice 1122F are respectively adapted to the second conducting end 1321F and the second connecting end 1322F of the second conducting tube 132F, so that the second conducting tube 132F can be held suspended by the second holding part 1324F. It is worth noting that the first conductive tube 131F and the second conductive tube 132F are kept suspended, which makes the first conductive tube 131F and the second conductive tube 132F less susceptible to stress and deformation (if the first conductive tube 131F and the second conductive tube 132F are deformed, it may damage the first conductive channel 1310F formed by the first conductive tube 131F and the second conductive channel 1320F formed by the second conductive tube 132F, and may also damage the fixed valve plate 121F and the conductive part 112F, and may also make it impossible for the fixed valve plate 121F and the conductive part 112F to be pressed tightly and sealed, which may further lead to internal leakage between other channels other than the jet channel).

Figures 8 to 13C As shown, optionally, the planar valve 10F for a water softener according to an embodiment of the present invention further includes a sealing gasket 1217F, wherein the sealing gasket 1217F is disposed between the valve core 12F and the valve body 11F.
