Description

[0002] With the development of economy and the progress of society, people's demand for the quality of life is getting higher and higher, and various water treatment equipment is applied to people's life. Common water treatment equipment includes water softener and water purifier. Among them, the water softener is widely used in people's life because it can remove calcium and magnesium ions in water and reduce water hardness.

[0003] In the existing water softener, the multi-way valve is a core component for controlling the flow direction of water in the integrated waterway. By controlling the switching of the multi-way valve in different stations, the water flow can be controlled to flow in different directions in different structures. The multi-way valve generally includes a valve core assembly, a moving valve plate and a fixed valve plate. The fixed valve plate is attached to the bottom of the moving valve plate, and the valve core assembly is attached to the top of the fixed valve plate. In actual water supply, the fixed valve plate and the moving valve plate are tightly attached under the action of fluid pressure, and the valve core assembly and the moving valve plate are in a separated trend under the action of liquid pressure. Therefore, a corresponding sealing structure needs to be provided between the valve core assembly and the moving valve plate to ensure the sealing effectiveness of the two.

[0004] However, when the liquid pressure between the valve core assembly and the moving valve plate is too large, the gap between the two generates large fluctuations, which exceeds the effective sealing amount of the sealing structure, and the multi-way valve will leak, affecting the soft water performance of the water softener or wasting water sources, or even causing the phenomenon of soft water function failure due to too much leakage.

[0037] An embodiment of the present application provides a water softener (not shown in the figure), which removes calcium and magnesium ions in raw water through ion exchange resin in a resin tank, so as to reduce water hardness and provide soft water with low calcium and magnesium ion content for users. The water softener comprises an integrated water path, a water softening device and a salt supply device connected to the integrated water path, and a multi-way valve provided in the integrated water path and used for controlling water flow direction.

[0038] The multi-way valve has seven working positions, i.e., a water supply position, a backwashing position, a first regeneration position, a slow washing position, a second regeneration position, a water supplementing position and a forward washing position. The multi-way valve can be switched between the working positions, so that the water softener has seven states, i.e., a water supply state, a backwashing state, a first regeneration state, a slow washing state, a second regeneration state, a water supplementing state and a forward washing state.

[0039] Referring to Figures 1 to 6 An embodiment of the present application further provides a multi-way valve 100, which comprises a valve body 70, a valve core assembly 10, a moving valve plate 30 and a fixed valve plate 50. The valve body 70 has a valve cavity. The fixed valve plate 50 is attached to the bottom of the moving valve plate 30. The valve core assembly 10 is attached to the top of the fixed valve plate 50. The valve core assembly 10 is assembled on the valve body 70 together with the moving valve plate 30 and the fixed valve plate 50, and communicates with the valve cavity to form a water flow channel. When the valve core assembly 10 and the moving valve plate 30 rotate relative to the fixed valve plate 50, the multi-way valve 100 can communicate with different water flow channels, so as to be switched to different working positions.

[0040] As described in the background, when the water softener performs water supply work, raw water generally enters from the periphery of the moving valve plate 30, and a water outlet channel is arranged at the center of the moving valve plate 30 to flow waste water to the outside. Since the water outlet channel communicates with the outside, the raw water inlet is generally a high-pressure end, and the center water outlet is a low-pressure end. Under the action of liquid pressure, the fixed valve plate 50 and the moving valve plate 30 are pressed tightly, and the two are closely attached. Under the action of high and low pressure, a gap a is easily generated between the moving valve plate 30 and the valve core assembly 10, and the two are in a trend of separation.

[0041] To solve this problem, generally, a sealing structure is arranged between the moving valve plate 30 and the valve core assembly 10 to ensure the sealing connection between the moving valve plate 30 and the valve core assembly 10, so as to avoid the gap a between the moving valve plate 30 and the valve core assembly 10, thereby avoiding the leakage of the multi-way valve 100. However, when the pressure difference between the high pressure of the inlet water and the low pressure of the outlet water is too large, the gap a between the valve core assembly 10 and the moving valve plate 30 will also fluctuate greatly. When the gap a exceeds the effective sealing amount of the sealing structure, the multi-way valve 100 will still leak, which will affect the soft water performance of the water softener or waste water, and even cause the phenomenon of function failure of the water softener due to too much leakage.

[0042] To solve the above problems, referring to Figures 2 to 5 The application provides a multi-way valve 100, which comprises a valve core assembly 10, a moving valve plate 30 and a sealing member 40. The moving valve plate 30 is arranged on one side of the valve core assembly 10. The valve core assembly 10 has a first pipe section 14. The moving valve plate 30 has a second pipe section 31. The first pipe section 14 and the first pipe section 14 are in communication to form an outlet water flow channel of the multi-way valve 100, which can be used to flow out waste water.

[0043] The sealing member 40 is arranged between the valve core assembly 10 and the moving valve plate 30. The sealing member 40 comprises a body 41, a first sealing part 42 and a second sealing part 43 which are connected to the body 41 and protrude in a first direction. The first sealing part 42 is in sealing cooperation with the valve core assembly 10 in the first direction. The second sealing part 43 is in sealing cooperation with the moving valve plate 30 in the first direction. The first direction intersects the stacking direction of the moving valve plate 30 and the valve core assembly 10.

[0044] In this way, the sealing member 40 can seal the connection position of the moving valve plate 30 and the valve core assembly 10, so as to avoid the leakage of the first pipe section 14 and the second pipe section 31 at the connection position of the moving valve plate 30 and the valve core assembly 10. Further, the first sealing part 42 and the second sealing part 43 protrude in the first direction. The first sealing part 42 is in sealing cooperation with the valve core assembly 10 in the first direction. The second sealing part 43 is in sealing cooperation with the moving valve plate 30 in the first direction. In this way, when the valve core assembly 10 and the moving valve plate 30 have a large gap a in the stacking direction, the sealing compression amount of the first sealing part 42 and the second sealing part 43 in the first direction will not be affected, that is, the sealing performance of the sealing member 40 in the first direction will not be affected by the size of the gap a in the stacking direction. Therefore, the sealing member 40 can still ensure good sealing performance when the gap a between the valve core assembly 10 and the moving valve plate 30 fluctuates greatly.

[0045] Specifically, the sealing member 40 can be sleeved on the outer periphery of the second pipe section 31. On one hand, the first sealing part 42 protruding in the first direction is in sealing cooperation with the valve core assembly 10. On the other hand, the sealing member 40 is in sealing cooperation with the pipe wall forming the second pipe section 31, so as to seal the outlet water flow channel.

[0046] Further, referring to Figure 6 , the sealing member 40 is in a sealing ring structure, the first sealing part 42 is a part protrudingly arranged at the outer ring of the sealing ring, the second sealing part 43 is a part protrudingly arranged at the sealing ring towards the valve disc 30, and the sealing ring structure can be integrally formed, thereby making the processing of the sealing member 40 simple.

[0047] In one of the embodiments, referring to Figure 3 , the valve core assembly 10 comprises the gland 11, the valve core 12 and the reinforcing plate 13, the valve core 12 is rotationally press-fitted on the gland 11 and connected with the valve disc 30, when the multi-way valve 100 needs to switch to various stations, the valve core 12 drives the valve disc 30 to rotate relative to the valve core assembly 10, thereby rotating relative to the gland 11 to communicate different passages. It is worth noting that in these stations, the water outlet flow channel formed by the first pipe segment 14 on the valve core 12 and the second pipe segment 31 on the valve disc 30 is always kept unobstructed to discharge waste water. The reinforcing plate 13 is press-fitted on one side of the gland 11 and fixedly connected with the gland 11 and the valve body 70 to increase the connection strength of the valve core assembly 10 and the valve body 70.

[0048] Further, the multi-way valve 100 further comprises the valve body 70, the valve core assembly 10 and the valve disc 30 are assembled in the valve body 70, the gland 11 is fixedly connected with the valve body 70, and at least part of the valve core 12 protrudes out of the gland 11 to discharge water in the water outlet flow channel.

[0049] When the valve core 12 and the valve disc 30 are subjected to pressure, they will slightly move away from each other in the stacking direction, at this time, the first sealing part 42 slides relative to the valve core assembly 10 in the stacking direction, and the second sealing part 43 slides relative to the valve disc 30 in the stacking direction, however, the sealing state between the two and the valve core assembly 10 and the valve disc 30 in the first direction does not change, at this time, the water in the water outlet flow channel still cannot be discharged through the gap a to ensure the sealing effect of the sealing member 40.

[0050] In one of the embodiments, referring to Figures 4 to 5 , the sealing member 40 further comprises a third sealing part 44, the third sealing part 44 is connected with the body 41 and protrudes away from the first sealing part 42 in the stacking direction, and the third sealing part 44 is sealingly matched with the valve disc 30 in the stacking direction.

[0051] The third sealing part 44 and the second sealing part 43 are both used for sealingly matching with the valve disc 30, the second sealing part 43 seals in the first direction, and the third sealing part 44 seals in the stacking direction, thereby providing sealing in two directions to ensure that the valve disc 30 and the valve core assembly 10 are sealed in place.

[0052] When the gap a between the valve disc 30 and the spool assembly 10 fluctuates to a value greater than the compression amount of the third sealing portion 44, the sealing effect of the third sealing portion 44 is lost, and at this time, the second sealing portion 43 still has a sealing effect although it moves in the stacking direction.

[0053] Specifically, the spool assembly 10 and the valve disc 30 are in a trend of being separated under the action of liquid pressure, and due to the manufacturing tolerance of the spool assembly 10 and the valve disc 30 in the stacking direction, the gap a between the spool assembly 10 and the valve disc 30 finally fluctuates greatly. In the extreme case of the height dimension of each part after assembly, the fluctuation size of the gap a between the spool assembly 10 and the valve disc 30 is about 0.8 mm. Under the action of the limit pressure 3.2 MPa or water hammer, the related force parts deform, causing the distance between the spool assembly 10 and the valve disc 30 to further increase, and the deformation amount in the extreme case is about 1.1 mm.

[0054] At this time, if the compression amount of the third sealing portion 44 is less than 1.1 mm, after the gap a between the spool assembly 10 and the valve disc 30 becomes 1.1 mm, the third sealing portion 44 completely separates from the valve disc 30, and the first sealing portion 42 still seals with the valve disc 30 after sliding a distance of 1.1 mm in the stacking direction.

[0055] In this way, by adopting the double sealing structure design, on the one hand, the defects of a single sealing structure can be reduced, and in the extreme case, the single sealing can be lost and water leakage can occur. On the other hand, the compression amount of the single sealing can be prevented from being too large, which can cause the compression ratio of the first sealing portion 42 to exceed the limit value and cause the first sealing portion 42 to crack, and the problem of premature aging and failure of the sealing can be solved.

[0056] In one embodiment, the stacking direction is the axial direction L1 of the spool assembly 10, and the first direction is the radial direction L2 of the spool assembly 10. The first sealing portion 42 and the second sealing portion 43 seal the spool assembly 10 and the valve disc 30, respectively, along the radial direction L2 of the spool assembly 10, and are not affected by the movement of the spool assembly 10 and the valve disc 30 in the axial direction L1. The third sealing portion 44 seals the valve disc 30 along the axial direction L1 of the spool assembly 10 to form a double sealing with the second sealing portion 43.

[0057] Specifically, the second sealing portion 43 and the valve disc 30 are in interference fit in the first direction, and the third sealing portion 44 and the valve disc 30 are in interference fit in the stacking direction, so that the second sealing portion 43 and the third sealing portion 44 have a certain compression amount when they are in a sealing state. When the gap a between the valve disc 30 and the spool assembly 10 fluctuates greatly, the compression amount of the third sealing portion 44 has a large adjustment range and will not be easily lost.

[0058] In one embodiment, the valve core assembly 10 has a mating sealing groove, a first sealing part 42 is sealed and inserted into the mating sealing groove along a first direction, and the first sealing part 42 can slide back and forth in the mating sealing groove along the stacking direction.

[0059] The configuration of the mating sealing groove provides a limit to the movement of the first sealing part 42 in the stacking direction. The first sealing part 42 can only slide up and down within the mating sealing groove, thereby mitigating the fluctuation of the gap a between the valve core assembly 10 and the moving valve plate 30.

[0060] Furthermore, in conjunction with the formation of the sealing groove, a first-direction recess can be formed directly on the valve core assembly 10, or it can be formed in other ways.

[0061] In one embodiment, see [reference] Figure 5 The valve core assembly 10 has a receiving groove b facing the moving valve plate 30. At least a portion of the body 41 extends into the receiving groove b. A first sealing part 42 is formed on the outer edge of the body 41 extending into the receiving groove b and protrudes outward from the outer edge of the body 41. The groove wall of the receiving groove b is recessed to the side away from the body 41 to form a mating sealing groove.

[0062] The sealing member 40, which is located between the valve core assembly 10 and the moving valve plate 30, firstly inserts a portion of its body 41 into the receiving groove for sealing. Then, the first sealing part 42, which protrudes from its outer edge, seals and engages with the mating sealing groove on the wall of the receiving groove b, thereby improving the sealing effect. Even if there is a gap a fluctuation between the moving valve plate 30 and the valve core assembly 10, due to the limiting relationship between the mating sealing groove and the first sealing part 42, the part of the body 41 extending into the receiving groove b will not detach from the receiving groove b, thus ensuring the effective sealing function of the first sealing part 42.

[0063] Meanwhile, the other surfaces of the body 41 extending into the receiving groove b can seal with the groove wall of the receiving groove b to improve the sealing effect.

[0064] In one embodiment, see [reference] Figure 2 and Figure 3 The multi-way valve 100 also includes a fixed valve plate 50, which is mounted on the side of the movable valve plate 30 away from the valve core assembly 10. The fixed valve plate 50 is generally provided with multiple connecting holes. The movable valve plate 30 and the valve core assembly 10 rotate relative to the fixed valve plate 50 to connect different connecting holes so as to switch the multi-way valve 100 to different working positions.

[0065] According to another aspect of this application, a water softener is also provided, including the multi-way valve 100 in the above embodiments. Since the water softener includes any feature of any of the above multi-way valves 100, the water softener provided by this application has the advantages of any of the above embodiments, which will not be repeated here.

[0066] Any technical features in the above embodiments can be combined, and for the sake of brevity, not all possible combinations are described above, however, as long as the combinations do not conflict with each other, they should be considered to be within the scope of the present disclosure.

[0067] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
