Description

Technical Field

[0001] The utility model relates to an electric valve, in particular to an electric valve capable of preventing interface water leakage. Background Art

[0002] The operating force of electric valves is greater than that of ordinary valves, and they are not easily stuck and damaged inside. Their control systems are relatively complex, and they are usually installed horizontally in pipelines. Although existing electric valves avoid manual opening and closing, liquid may leak when they are connected to adjacent pipes during use. When water leaks at the interface, the traditional approach is to replace the gasket or strengthen the fastening of the interface, but this approach can only temporarily relieve the problem for a period of time. After a while, water leakage will occur again. Moreover, as the number of times the gasket is replaced and the fastening of the interface is strengthened increases, the sealing of the connection will eventually become lower due to multiple disassembly or tightening of the interface, and water leakage will increase instead. Utility Model Content

[0003] The utility model aims to provide an electric valve for preventing interface water leakage, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: an electric valve with anti-interface water leakage protection, comprising an electric valve body, wherein the pipeline interface end of the electric valve body is fixedly connected to the main pipeline interface end through a flange via an anti-leakage component.

[0005] The end faces of the pipeline interface end of the electric valve body and the main pipeline interface end are adapted to the structure of the water leakage prevention component.

[0006] The anti-leakage component comprises a first pipe section, a middle pipe section and a second pipe section, and the surfaces of the first pipe section, the middle pipe section and the second pipe section are all frosted.

[0007] The diameter of the first pipeline section is smaller than the diameter of the middle pipeline section and is equal to the diameter of the second pipeline section.

[0008] The length of the first pipeline section is equal to the length of the second pipeline section.

[0009] Elastic sealing sleeves are arranged on the surfaces of the first pipeline section and the second pipeline section.

[0010] The elastic sealing sleeve is provided with a plurality of annular sealing protrusions at intervals.

[0011] The upper part of the annular sealing protrusion is embedded in the annular embedding groove arranged on the inner wall of the pipeline interface end of the electric valve body and the main pipeline interface end, and the lower part thereof is embedded in the embedding groove on the surface of the first pipeline section and the second pipeline section.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] 1. The utility model adopts a water-leakage-proof component, and a water-leakage-proof component is arranged at the connection between the pipeline interface end of the electric valve body and the main pipeline interface end. The water-leakage-proof component includes a first pipeline section, an intermediate pipeline section and a second pipeline section. The diameter of the first pipeline section is smaller than the diameter of the intermediate pipeline section and equal to the diameter of the second pipeline section, so that the first pipeline section, the intermediate pipeline section and the second pipeline section can form a stepped structure. Under the structure in which the end faces of the pipeline interface end of the electric valve body and the main pipeline interface end are matched, the distance of water leakage is increased and tortuous, thereby greatly reducing the leakage at the interface connection. At the same time, with the use of a sealing gasket, the sealing performance of the overall structure can be further improved to ensure the stable operation of the water flow without leakage. The overall surface is frosted to increase the contact friction and prevent water from penetrating into the gap to reduce the firmness of the installation of the water-leakage-proof component.

[0014] 2. In the utility model, an elastic sealing sleeve is provided on the surface of the first pipe section and the second pipe section, and a plurality of annular sealing convex parts are provided on the elastic sealing sleeve at intervals. The upper part of the annular sealing convex part is embedded in the annular embedding groove provided on the inner wall of the pipe interface end of the electric valve body and the main pipe interface end, and the lower part thereof is embedded in the embedding groove on the surface of the first pipe section and the second pipe section. The provision of the elastic sealing sleeve can improve the sealing performance of the contact between the first pipe section and the second pipe section and the inner wall of the pipe interface end of the electric valve body and the main pipe interface end, and the elastic sealing sleeve is provided with a plurality of annular sealing convex parts at intervals, which can further improve the sealing performance, effectively block the penetration of water flow, and ensure the stable operation of water flow without leakage.
