Description

Technical Field

[0001] The utility model belongs to the technical field of valves and relates to a solenoid valve, in particular to a novel solenoid valve body. Background Art

[0002] The valve body of the existing solenoid valve has a lower connecting plate, the top of the lower connecting plate is fixedly connected to the upper connecting plate, which is in turn connected to the upper structure of the solenoid valve, and the upper and lower connecting plates are connected by bolts. However, in the batch assembly process of the existing solenoid valve, it is found that when the upper and lower connecting plates are installed in position, the screw holes of the upper and lower connecting plates need to be positioned, and then the bolts are installed. Such a positioning process requires manual identification, because once there is an offset, although the bolts can be driven in, it will cause problems with the sealing of the upper and lower connecting plates, and the assembly process is more troublesome. Summary of the invention

[0003] The utility model aims to solve the above problems existing in the prior art and provides a solenoid valve body with a self-positioning effect during the assembly process.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a new type of solenoid valve body, including a valve body with a lower connecting plate, characterized in that a positioning groove is provided inwardly on the top surface of the lower connecting plate, and the upper connecting plate is installed in the positioning groove. The plurality of screw holes on the lower connecting plate correspond to the plurality of screw holes on the upper connecting plate as the upper connecting plate is installed, and the upper and lower connecting plates are connected by bolts. A sealing groove is provided on the inner wall of the lower connecting plate, and a sealing device is installed in the sealing groove. The sealing device is L-shaped and consists of a positioning end and a bent end. The top of the positioning end is inserted into the sealing groove and fits against the groove wall of the sealing groove. The outer end of the bent end extends outward and contacts with the upper connecting plate. When contacting the upper connecting plate, the outer end portion of the bent end bends downward along the installation direction of the upper connecting plate.

[0005] In the above-mentioned novel solenoid valve body, a process groove is provided on the inner wall of the lower connecting plate and located below the sealing groove.

[0006] In the above-mentioned novel solenoid valve body, the lower connecting plate and the upper connecting plate are rectangular or circular structures.

[0007] Compared with the prior art, the new solenoid valve body has the advantages of accurate screw hole positioning, stable and convenient structural installation and good sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a three-dimensional diagram of the valve body of the novel solenoid valve.

[0009] Figure 2 It is a cross-sectional view of the upper and lower connecting plates.

[0010] In the figure, 1, lower connecting plate; 2, valve body; 3, positioning groove; 4, screw hole; 5, sealing groove; 6, positioning end; 7, bending end; 8, process groove; 9, upper connecting plate. DETAILED DESCRIPTION

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0012] like Figure 1 , Figure 2 As shown, the valve body of the new solenoid valve comprises a valve body 2 having a lower connecting plate 1, a positioning groove 3 is provided inwardly on the top surface of the lower connecting plate 1, an upper connecting plate 9 is installed in the positioning groove 3, a plurality of screw holes 4 on the lower connecting plate 1 and a plurality of screw holes 4 on the upper connecting plate 9 are formed correspondingly with the installation of the upper connecting plate 9, and the upper and lower connecting plates 1 are connected by bolts. In order to ensure the sealing stability of the positioning structure, as shown in FIG. Figure 2 As shown, a sealing groove 5 is opened on the inner wall of the lower connecting plate 1, and a sealing device is installed in the sealing groove 5. The sealing device is L-shaped and consists of a positioning end 6 and a bending end 7. The top of the positioning end 6 is inserted into the sealing groove 5 and fits against the groove wall of the sealing groove 5. The outer end of the bending end 7 extends outward and contacts with the upper connecting plate 9. When contacting the upper connecting plate 9, the outer end portion of the bending end 7 bends downward along the installation direction of the upper connecting plate 9.

[0013] To be more specific, a process groove 8 is provided on the inner wall of the lower connecting plate 1 and below the sealing groove 5 to facilitate the outer end of the bending end 7 to bend downward, thereby forming a downward bending space for the outer end and fitting and sealing with the upper connecting plate 9.

[0014] Since the sealing device itself is made of rubber material, after the upper connecting plate 9 is positioned and assembled, the L-shaped sealing device presents an S-shape.

[0015] The bottom end of the sealing groove 5 is chamfered to prevent the bent end 7 from being damaged when being bent.

[0016] A slot for the top of the positioning end 6 to be inserted into is provided on the slot wall of the sealing slot 5 .

[0017] To further elaborate, the lower connecting plate 1 and the upper connecting plate 9 are rectangular or circular structures. The positioning and sealing structure can be applied to connecting plates of various shapes and has strong versatility.

[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0019] Although the terms such as lower connecting plate 1, valve body 2, positioning groove 3, screw hole 4, sealing groove 5, positioning end 6, bent end 7, process groove 8, upper connecting plate 9 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
