Description

Technical Field

[0001] The present application relates to the technical field of electric valve manufacturing, and in particular to an electric valve with multi-point positioning. Background Art

[0002] At present, the valve body of the electric valve is generally made of copper, and the valve body is manufactured by casting or forging, but the manufacturing cost of the copper material is relatively high.

[0003] Since copper has product regulations on the valve body structure of the electric valve, it is not easy to use other materials. When the valve body structure is split for production, the valve body can be designed as a valve body seat and a valve cover. It can be seen that the valve body seat still needs to be made of copper, and we found that the valve cover can be produced with copper material, of course, other materials can also be used, and among the existing materials, stainless steel can also be used, but the valve cover made of stainless steel cannot meet the structural assembly requirements. The cost of forged stainless steel valve covers is still very high, and processing is difficult. The upper assembly can effectively close the valve body seat opening.

[0004] Therefore, the technical problem that needs to be solved is how to improve the structure of the stainless steel valve cover and the copper valve body seat to enable better assembly, reduce production costs and improve production efficiency. Utility Model Content

[0005] In view of the above-mentioned shortcomings (problems) of the prior art, in order to improve production efficiency and reduce manufacturing costs, the present application provides an electric valve with multi-point positioning.

[0007] The valve cover is formed by stamping to have at least one positioning column and one positioning strip, and the outer edge of the positioning strip is consistent with the assembly opening.

[0008] Preferably, the valve cover is provided with a riveted sleeve, a rotating shaft is rotatably connected in the riveted sleeve, a swing arm is fixedly connected to the lower end of the rotating shaft, and a ball valve is fixedly connected to the other end of the swing arm. The rotating shaft is not located at the center of the valve cover.

[0009] The positioning bar is in the shape of a ring with a notch, and the rotating shaft is located at the notch.

[0010] Preferably, two positioning columns are provided, respectively close to two opposite sides of the valve cover.

[0011] Preferably, the assembly platform and the valve cover are both rectangular structures, and fixing holes are provided at the four corners of the rectangle.

[0012] Preferably, rivets or bolts are installed in the fixing holes to fix the valve body seat and the valve cover.

[0013] In summary, the present application includes at least one of the following beneficial technical effects:

[0014] Compared with copper valve covers, stainless steel valve covers have lower production costs and can be reliably processed and assembled. Positioning posts and positioning strips are used to achieve rapid positioning to improve assembly efficiency. Multiple points and edge positioning of positioning strips are used to improve positioning stability and avoid position deviation during the initial positioning process.

The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0024] The following is combined with Figure 1-4 The specific implementation methods of this application are further described. Example

[0025] The present application embodiment discloses a multi-point positioning electric valve, referring to Figure 1 As shown, it includes a valve body seat 1 made of copper and a valve cover 2 made of stainless steel (not limited to copper). The use of stainless steel can reduce the production cost (compared to copper processing). Alternatively, an injection-molded plastic valve cover 2 can be used.

[0026] The valve body seat 1 is provided with an inner cavity 11, an assembly port 12, and an assembly platform 13. The assembly platform 13 has a horizontal mounting surface 14, so that the mounting surface 14 can fully contact the valve cover 2. The assembly port 12 is located at the center of the mounting surface 14, and a plurality of positioning holes 15 are provided on the mounting surface 14. The mounting surface 14 is also provided with a sealing groove 16. The sealing ring 9 is assembled in the sealing groove 16, and the sealing ring 9 is elastic. The sealing here is achieved by pressing the valve cover 2.

[0027] The valve cover 2 is formed by stamping to have at least one positioning column 22 and positioning strip 21, and the outer edge of the positioning strip 21 is consistent with the assembly opening 12. Since the valve cover 2 is made of stainless steel, the sheet metal manufacturing process can be used to stamp the positioning column 22 and the positioning strip 21, which greatly improves production efficiency.

[0028] exist Figure 2 , Figure 3 and Figure 4In the embodiment, a riveted sleeve 3 is provided on the valve cover 2, a rotating shaft 4 is rotatably connected in the riveted sleeve 3, a swing arm 5 is fixedly connected to the lower end of the rotating shaft 4, a ball valve 6 is fixedly connected to the other end of the swing arm 5, and the rotating shaft 4 is not located at the center of the valve cover 2. When the rotating shaft 4 rotates, the swing arm 5 can realize the swing of the ball valve 6, and the ball valve 6 can realize action.

[0029] The positioning strip 21 is annular with a notch 23, and the rotating shaft 4 is located at the notch 23. This design can effectively realize the assembly positioning function. During assembly, the initial positioning and the depth positioning can be quickly realized. The initial positioning can be realized by the positioning column 22. The depth positioning relies on the edge cooperation of the positioning strip 21, so that the installation position of the valve cover 2 is more accurate.

[0030] Specifically, two positioning posts 22 are provided, respectively close to two opposite sides of the valve cover 2. The positioning posts 22 pass through two points, that is, the preliminary positioning can be completed. Of course, more can be provided, but the cost will increase. Therefore, considering the cost control, two positioning posts 22 are the preferred solution.

[0031] In this solution, the assembly platform 13 and the valve cover 2 are both rectangular structures, and fixing holes 7 are provided at the four corners of the rectangle. Specifically, they can be square. Finally, rivets or bolts 8 are installed in the fixing holes 7 to achieve the fixing of the valve body seat 1 and the valve cover 2.

[0032] In summary, it can be seen that the stainless steel valve cover 2 has a lower production cost than the copper valve cover 2, and can be reliably processed and assembled. The positioning column 22 and the positioning strip 21 are used to achieve rapid positioning to improve assembly efficiency. Multiple points and edge positioning of the positioning strip 21 are used to improve the stability of positioning and avoid position deviation during the initial positioning process. The eccentric rotating shaft 4 position and the swing arm 5 are used to achieve the swinging movement of the ball valve 6, thereby realizing the opening and closing of the valve body seat 1 channel by the ball valve 6. The positioning of the valve cover 2 is used to improve the position reliability of the ball valve 6 assembly.

[0033] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
