Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more specifically, to the valve body of a soft water valve. Background Technology

[0002] A water softener is a device that uses ion exchange to remove metal ions such as calcium and magnesium from water, effectively solving the problem of high water hardness. The softening valve is one of the key components ensuring the normal operation of the water softener. The softening valve has a valve body, and the valve core is installed inside the valve body. Controlling the movement of the valve core switches the water flow.

[0003] Existing soft water valves rely on a motor-driven valve core to reciprocate and control water circuit switching. The valve core needs to maintain accurate positioning and reliable sealing during this movement. However, valve cores typically have a certain length, making them prone to wobbling and misalignment during operation. Over time, this can lead to uneven gaps between the valve core's sealing end and the valve body's inner wall, increased resistance, insufficient motor thrust, and valve core jamming. Utility Model Content

[0004] This invention aims to solve the problem of easy wobbling of the valve core in existing technologies. Therefore, this invention provides a valve body for a soft water valve that improves the stability of the valve core during movement.

[0005] The valve body of the soft water valve of this utility model can be achieved through the following technical solutions:

[0006] A valve body for a soft water valve, the soft water valve including a valve core and a valve body, the valve core being movably disposed in the valve body to switch water circuits, the valve body including:

[0007] The valve seat includes a raw water inlet pipe and a soft water outlet pipe. The valve seat has an internal valve cavity and a water passage. The raw water inlet pipe communicates with the valve cavity, and the water passage also communicates with the valve cavity. The valve seat is equipped with a raw water outlet, a soft water inlet, a brine tank connection port, and a wastewater outlet. The raw water outlet and soft water inlet are used to communicate with a resin tank, and the soft water inlet is connected to the soft water outlet pipe. Both the brine tank connection port and the wastewater outlet are connected to the water passage.

[0008] An end cap is provided, which is connected to the valve seat and seals the valve cavity. The end cap is provided with a guide hole for the valve core to pass through, and the guide hole is located on the same horizontal line as the water passage.

[0009] In one embodiment, the guide hole extends toward at least one side of the end cap to form a guide tube.

[0010] In one embodiment, the end cap is provided with a plurality of support columns, which are located inside the valve cavity, and the plurality of support columns are circumferentially distributed along the periphery of the guide hole or guide tube.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0027] In the description of this utility model, the terms "first," "second," "third," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0028] Please see Figure 1-6 This embodiment provides a water softener valve body, which includes a valve core 200 and a valve body 100. The water softener valve is used to control the operation of a water softener. Figure 6This is a schematic diagram of the soft water valve in this embodiment. The valve core 200 is movably disposed in the valve body 100 to switch water paths, thereby realizing the switching of different working states of the water softener. In this embodiment, the valve body 100 includes a valve seat 11 and an end cap 12. The valve seat 11 includes a raw water inlet pipe 111 and a soft water outlet pipe 112. The raw water inlet pipe 111 is connected to the tap water end, and the soft water outlet pipe 112 is connected to the water user end. The valve seat 11 is provided with a raw water outlet 115, a soft water inlet 116, a brine tank connection port 1141, and a wastewater outlet 1142. The raw water outlet 115 and the soft water inlet 116 are used to communicate with the resin tank to form a water path in the resin tank. It should be noted that the water in the valve body 100 enters the resin tank from the raw water outlet 115, and the water after exchanging with the resin flows out from the soft water inlet 116. If water in valve body 100 enters the resin tank through soft water inlet 116, the water, after exchanging with the resin, flows out through raw water outlet 115. Valve seat 11 has a valve cavity 113 and a water passage 114 formed inside. One side of valve cavity 113 has an opening, and the other side is connected to the water passage 114. Raw water inlet pipe 111 is connected to valve cavity 113, allowing raw water to flow into valve cavity 113 from raw water inlet pipe 111. By controlling the opening and closing of water passage 114, the entry of raw water into the resin tank can be controlled. Soft water inlet 116 is connected to soft water outlet pipe 112, and brine tank connection port 1141 and wastewater outlet 1142 are both connected to water passage 114. When the water softener is in operation, raw water enters the resin tank from the raw water outlet 115. After ion exchange by the resin, the raw water becomes soft water. The soft water flows out of the resin tank from the soft water inlet 116 and is finally delivered to the user's end through the soft water outlet pipe 112.

[0029] End cap 12 is connected to valve seat 11, and end cap 12 seals valve cavity 113. Specifically, end cap 12 is installed at the opening of valve cavity 113 to form a leak-proof seal. End cap 12 has a guide hole 1211 for valve core 200 to pass through, and guide hole 1211 is located on the same horizontal line as water passage 114. After valve core 200 passes through guide hole 1211, it enters water passage 114. The reciprocating motion of valve core 200 controls its position in water passage 114, thereby achieving water circuit switching. During the movement, valve core 200 is supported and guided by end cap 12, causing valve core 200 to reciprocate along the horizontal line, limiting radial displacement of valve core 200, thereby reducing swaying and preventing offset of the part away from water passage 114. This makes valve core 200 less prone to jamming during movement, and the driving force required for water circuit switching is also smaller.

[0030] It should be noted that, in this embodiment, the movement of the valve core 200 can be controlled by a mechanical device or automatically controlled by an electric device, and the specific implementation method is not limited in this embodiment.

[0031] Please refer to the following: Figure 3 and Figure 5 The end cap 12 is provided with several support columns 122. The support columns 122 are located inside the valve cavity 113. The support columns 122 are distributed in a circle around the guide hole 1211. That is, the support columns 122 form a circle, so that when the valve cavity 113 is deep, the valve core 200 part located in the valve cavity 113 is limited by the support columns 122.

[0032] To ensure greater stability of the valve core 200 during movement and to accommodate a longer valve core 200, the guide hole 1121 extends towards at least one side of the end cover 12 to form a guide tube 112. This means the valve core 200 is always constrained by the guide tube 112 during movement. Since the valve core 200 needs to accommodate the length of the water passage 114, a longer water passage 114 typically results in a longer valve core 200. In this case, the valve core 200 is more prone to misalignment when moving away from the water passage 114. Therefore, the guide hole 1121 extends towards the side of the end cover 12 away from the valve cavity 113 to form a guide tube 112, thus better constraining the valve core 200 during movement and maintaining stability. In this embodiment, the guide hole 1121 extends towards both sides of the end cover 12 to form guide tubes 112, ensuring that one end of the valve core 200 remains within the guide tube 112 while the other end moves within the water passage 114. Since the axis of the guide hole 112 and the water passage 114 are on the same horizontal line, it ensures that the valve core 200 always moves along the horizontal line, is not prone to deviation, and is smoother when switching water circuits. It also prevents gaps from forming between the valve core 200 and the inner wall of the water passage 114, thus avoiding water leakage. At this time, several support columns 122 are circumferentially distributed around the periphery of the guide tube 121.

[0033] Specifically, there is a gap between the guide tube 121 and the port of the water passage 114, so that the valve chamber 113 and the water passage 114 are not blocked, ensuring that the water in the valve chamber 113 can enter the water passage 114 more smoothly. In this embodiment, the length of the support column 122 is greater than the length of the guide tube 121, so that the support column 122 can abut against the port of the water passage 114, further guiding the movement of the valve core 200.

[0034] In this embodiment, the support column 122 can be a reinforcing rib around the guide tube 121, so that the support column 122 can play a certain role in reinforcing and supporting the guide tube 121.

[0035] Please see Figure 3-5 The end cap 12 is provided with a flange 123, which is inserted into the valve cavity 113 and is sealed to the inner wall of the valve cavity 113.

[0036] Specifically, the flange 123 has an annular groove, and a sealing ring 124 is installed in the annular groove. The sealing ring 124 is in a sealing fit with the inner wall of the valve cavity 113, thereby sealing the valve cavity 113 with the end cover 12 and sealing the valve seat 11. By providing the flange 123 on the end cover 12, the flange 123 is inserted into the valve cavity 113 during the assembly of the valve body 100, so that the end cover 12 can fit tightly with the inner wall of the valve cavity 113. This simplifies the operation and ensures good sealing between the end cover 12 and the valve seat 11.

[0037] More specifically, the valve seat 11 is provided with a stepped surface 1131, which is located on the inner wall of the valve cavity 113. The end cover 12 is provided with a limiting surface 125. The stepped surface 1131 and the limiting surface 125 abut against each other, which further ensures the tight fit between the end cover 12 and the valve seat 11 and avoids water leakage caused by partial displacement of the end cover 12 when the valve core 200 moves.

[0038] Furthermore, a positioning post 117 is provided on the stepped surface 1131, and a first positioning groove 1251 is provided on the limiting surface 125. When the end cover 12 is connected to the valve seat 11, the positioning post 117 is located in the first positioning groove 1251, so that the end cover 12 can be completely embedded in the valve seat 11, and the valve body 100 can be smaller and more aesthetically pleasing. In actual assembly, a mounting hole can be opened on the first positioning groove 1251. The mounting hole is adapted to the positioning post 117, and the fastener passes through the mounting hole and the positioning post 117 in sequence to strengthen the connection between the end cover 12 and the valve seat 11.

[0039] The valve seat 11 is also provided with a positioning rib 118, and the end cover 12 is provided with a second positioning groove 126. The positioning rib 118 is confined within the second positioning groove 126. During assembly, by positioning the positioning rib 118 with the second positioning groove 126, the assembly is simplified, and other parts can be matched accordingly.

[0040] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. The protection scope of this utility model patent should be determined by the appended claims.
