Description

Technical Field

[0001] This utility model belongs to the field of valve technology, specifically relating to a plug multi-way valve that is easy to maintain. Background Technology

[0002] A plug valve is a type of valve that switches between multiple inlets and outlets by rotating an internal valve core (plug) to change the fluid flow path. A plug typically consists of a valve body and a valve core that rotates inside the valve body. Sealing plates are installed between the valve body and the valve core to create a seal and ensure stable flow. In practical applications, the valve core is usually rotated to regulate the flow. Because the plates are attached to the valve core, they wear down during use, eventually becoming less effective at blocking liquid flow. This requires opening the valve body to replace the plates. However, existing plug valves require removing the valve core from the valve body before replacing the plates, which is complex and inconvenient for plate replacement during actual operation. Utility Model Content

[0003] This utility model provides a plug valve that is easy to maintain, aiming to solve the problem that the plug valve is inconvenient to operate and maintain during the later maintenance and replacement of the valve plates in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a plug multi-way valve that is easy to maintain, comprising: The valve body has an inlet at one end and multiple outlets arranged circumferentially on the side wall of the valve body. The valve core is inserted inside the valve body and rotatably mounted on the valve body. The valve core has a cylindrical structure and a valve port for communicating with the water outlet is provided on the side wall of the valve core. A tile is installed between the valve body and the valve core, and a limiting platform for limiting the tile is provided at the end of the valve body away from the water inlet; A limiting ring is threaded to the inner wall of the water inlet on the valve body and is used to limit the tile inside the valve body.

[0005] In one possible implementation, a valve stem is fixedly mounted on the end of the valve core, and a valve cap for mounting the valve stem is provided at the end of the valve body away from the water inlet. The valve stem is rotatably disposed inside the valve cap and is sealed to the valve cap.

[0006] In one possible implementation, a plurality of limiting strips protrude from the inner wall of the valve core, the plurality of limiting strips being arranged at intervals along the circumference of the valve body, and the tile being installed between two adjacent limiting strips.

[0007] In one possible implementation, the ends of the plurality of limiting strips near the water inlet are located on the same plane, and the limiting ring can abut against the ends of the limiting strips.

[0008] In one possible implementation, when the limiting ring abuts against the end of the limiting strip, the valve core slides in conjunction with the limiting ring.

[0009] In one possible implementation, a sealing ring protrudes from the center of the tile, the thickness of the sealing ring being greater than the gap between the valve body and the valve core, and the sealing ring protruding from both the inner and outer sides of the tile.

[0010] In one possible implementation, the end of the limiting ring is provided with a plurality of vertical ribs, which are evenly spaced along the circumference of the limiting ring.

[0011] In one possible implementation, a plurality of drainage grooves are recessed on the outer side wall of the limiting ring, and the plurality of drainage grooves are arranged at intervals along the circumference of the limiting ring.

[0012] The solution shown in this application, compared with the prior art, features a cylindrical structure for both the valve body and valve core. The valve body is fitted onto the outside of the valve core, and the valve core is installed inside the valve body through the inlet and rotatably positioned within it. A sealing mechanism is achieved between the valve body and valve core by installing a retaining ring between them. Rotating the valve core allows switching between multiple outlet states. This application utilizes a limit ring threaded onto one end of the valve body inlet. After the valve core and retaining ring are installed inside the valve body, the limit ring secures them within the valve body. Furthermore, during prolonged use, if the retaining ring wears down and needs replacement, it can be removed from the valve body by disassembling the limit ring. No other structural components need to be disassembled. The structure is simple, operation is convenient, and maintenance of the multi-way valve is easy. Attached Figure Description

Detailed Implementation To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] Please refer to the following: Figures 1 to 4 The present invention provides a maintenance-friendly multi-way stopcock valve. The maintenance-friendly multi-way stopcock valve includes a valve body 1, a valve core 2, a valve plate 3, and a limiting ring 4. One end of the valve body 1 has an inlet, and multiple outlets are arranged circumferentially on the side wall of the valve body 1. The valve core 2 is inserted inside the valve body 1 and rotatably mounted on the valve body 1. The valve core 2 has a cylindrical structure, and its side wall has a valve port for communicating with the outlets. The valve plate 3 is installed between the valve body 1 and the valve core 2. A limiting platform 12 for limiting the valve plate 3 is provided at the end of the valve body 1 away from the inlet. The limiting ring 4 is threadedly connected to the inner wall of the inlet on the valve body 1 to limit the valve plate 3 inside the valve body 1.

[0016] The easy-to-maintain multi-way stopcock valve provided in this embodiment, compared with the prior art, has a cylindrical structure for both the valve body 1 and the valve core 2. The valve body 1 is fitted onto the outside of the valve core 2, and the valve core 2 is installed inside the valve body 1 through the inlet and rotatably disposed inside the valve body 1. A sealing mechanism is achieved between the valve body 1 and the valve core 2 by installing a plate 3 between them. Rotating the valve core 2 allows switching the water outlet states of multiple outlets. In this application, a limiting ring 4 is threadedly connected to one end of the valve body 1's inlet. After the valve core 2 and the plate 3 are installed inside the valve body 1, the limiting ring 4 limits the valve core 2 and the plate 3 within the valve body 1. Furthermore, during prolonged use, if the plate 3 wears and needs replacement, it can be removed from the valve body 1 by disassembling the limiting ring 4 for replacement. No other structural components need to be disassembled. The structure is simple, the operation is convenient, and it facilitates the maintenance of the multi-way valve.

[0017] Specifically, in this embodiment, when the tile 3 is installed between the valve body 1 and the valve core 2, the through hole on the tile 3 is connected to the water outlet, and a tile 3 is installed at each individual water outlet. When the valve port on the valve core 2 rotates to the corresponding water outlet, the remaining water outlets are sealed by the sealing between the remaining tiles 3 and the valve core 2.

[0018] In some embodiments, the valve core 2 may be adopted as follows: Figure 2 The structure shown. See also Figure 2A valve stem 21 is fixedly installed at the end of the valve core 2. A valve cap 11 for installing the valve stem 21 is provided at the end of the valve body 1 away from the inlet. The valve stem 21 is rotatably disposed inside the valve cap 11 and is sealed to the valve cap 11. The valve stem 21 is fixedly installed at the end of the valve core 2 and is coaxial with the valve core 2. The valve cap 11 is fixedly installed at the end of the valve body 1 and is coaxial with the valve body 1. When the valve core 2 is installed inside the valve, the valve stem 21 slides into the valve cap 11 and extends through the valve cap 11 to the outside of the valve body 1. A rotating part is provided in the middle of the valve stem 21 and is rotatably disposed inside the valve cap 11. A sealing ring is fitted on the outside of the rotating part to achieve a seal between the valve stem 21 and the valve cap 11.

[0019] Preferably, in this embodiment, the valve stem 21 and the valve core 2 are integrally formed. The valve body 1 and the valve cap 11 are integrally formed.

[0020] Specifically, in this embodiment, the valve cap 11 is located on the limiting platform 12 on the valve body 1.

[0021] In some embodiments, the valve core 2 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 Multiple limiting strips 13 protrude from the inner wall of the valve core 2, and are arranged at intervals along the circumference of the valve body 1. The tile 3 is installed between adjacent limiting strips 13. The length direction of the limiting strips 13 is along the axis of the valve body 1, and the limiting strips 13 and the valve body 1 are integrally formed. When the tile 3 is installed inside the valve body 1, its two sides abut against the side walls of adjacent limiting strips 13, thereby limiting the installation position of the outer canopy. This facilitates aligning the installation position of the tile 3, and when the valve core 2 rotates inside the valve body 1, it prevents the tile 3 from rotating with the valve core 2, improving the stability of the tile 3's installation position.

[0022] Specifically, in this embodiment, two limiting strips 13 located on both sides of the outlet on the valve body 1 form a group. The two limiting strips 13 form an installation gap for installing the tile 3. A support rib is provided protruding from the side of the limiting strip 13 near the outlet. The support rib protrudes from the limiting platform 12 on the valve body 1. When the tile 3 is installed between the two limiting strips 13, the end of the tile 3 abuts against the support rib. Thus, if the tile 3 is installed in the wrong position, it can be detected in time by the height difference between the tile 3 and the valve core 2.

[0023] In some embodiments, the aforementioned limiting strip 13 may be adopted as follows: Figure 2 , Figure 3 and Figure 4 The structure shown. See also... Figure 2 , Figure 3 and Figure 4Multiple limiting strips 13 are located on the same plane near the inlet, and the limiting ring 4 can abut against the end of the limiting strip 13. The end faces of the multiple limiting strips 13 form a limiting surface for limiting the movement of the limiting ring 4 into the valve body 1. When the limiting ring 4 is rotated to move into the valve body 1, the end face of the limiting ring 4 abuts against the end of the multiple limiting strips 13, thereby fixing the limiting ring 4 tightly inside the valve body 1, which facilitates fixing the position of the limiting ring 4.

[0024] In some embodiments, the aforementioned limiting ring 4 can be adopted as follows: Figure 2 , Figure 3 and Figure 4 The structure shown. See also... Figure 2 , Figure 3 and Figure 4 When the limiting ring 4 abuts against the end of the limiting strip 13, the valve core 2 slides against the limiting ring 4. When the limiting ring 4 abuts against the end face of the limiting strip 13, the valve core 2 is limited between the limiting ring 4 and the limiting platform 12 of the valve body 1, and the end face of the valve core 2 slides against the limiting ring 4. Therefore, tightening the limiting ring 4 will not affect the rotation of the valve core 2. The limiting strip 13 can be used to position the limiting ring 4, thus satisfying the limitation of the installation position of the valve core 2 without affecting the operation of the valve core 2 in the working state.

[0025] In some embodiments, the aforementioned tile 3 may be adopted as follows: Figure 3 , Figure 4 The structure shown. See also... Figure 3 , Figure 4 A sealing ring 31 protrudes from the center of the tile 3. The thickness of the sealing ring 31 is greater than the gap between the valve body 1 and the valve core 2, and the sealing ring 31 protrudes from both the inner and outer sides of the tile 3. The two sides of the sealing ring 31 protrude from the inner and outer sides of the tile 3, respectively. When the tile 3 is installed inside the valve body 1, the sealing ring 31 surrounds the outer ring of the outlet on the valve body 1, and the outer side of the sealing ring 31 abuts against the inner wall of the valve body 1. The inner side of the sealing ring 31 abuts against the outer surface of the valve core 2. This achieves a seal between the valve body 1 and the valve core 2. When the valve port on the valve core 2 rotates to the corresponding outlet on the valve body 1, communication is established between the corresponding outlet and the interior of the valve core 2.

[0026] Specifically, in this embodiment, the sealing ring 31 on the tile 3 protrudes from both the outer and inner sides of the tile 3. After the tile 3 is installed inside the valve body 1, both sides of the sealing ring 31 are deformed by compression to achieve a seal between the sealing ring 31 and the inner wall of the valve body 1 and the outer surface of the valve core 2. During use, the side of the sealing ring 31 closest to the valve core 2 is prone to wear and dimensional changes. The elastic deformation of the side of the sealing ring 31 closest to the inner wall of the valve body 1 pushes the tile 3 towards the valve core 2, achieving a self-repairing function and improving the service life of the multi-way valve.

[0027] In some embodiments, the aforementioned limiting ring 4 can be adopted as follows: Figure 2 The structure shown. See also Figure 2 The end of the limiting ring 4 has multiple vertical ribs 41 protruding outwards, and the multiple vertical ribs 41 are evenly spaced along the circumference of the limiting ring 4. An annular rib is protruding outwards at the end of the limiting ring 4 away from the valve core 2, and the vertical ribs 41 are fixedly installed between the annular rib and the limiting ring 4. The design of multiple vertical ribs 41 can enhance the overall strength of the limiting ring 4, and at the same time make it convenient for the operator to use tools to push the limiting ring 4 to rotate.

[0028] Specifically, in this embodiment, the limiting ring 4, the annular rib, and the vertical rib 41 are all integrally formed structures.

[0029] In some embodiments, the aforementioned limiting ring 4 can be adopted as follows: Figure 1 The structure shown. See also Figure 1 The outer wall of the limiting ring 4 is recessed with multiple drainage grooves 42, which are arranged at intervals along the circumference of the limiting ring 4. With the limiting ring 4 installed inside the valve body 1, the gap between the valve body 1 and the valve core 2 is connected to the water inlet through the drainage grooves 42. This allows residual water and sediment between the valve body 1 and the valve core 2 to be discharged after water supply is stopped, preventing sediment from accumulating inside the valve body 1.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
