Bidirectional electromagnetic valve

Abstract

The invention belongs to the technical field of electromagnetic valves, and particularly relates to a two-way electromagnetic valve which comprises a valve body. A first mounting opening and a secondmounting opening are formed in the left side and the right side of the valve body correspondingly; a middle partition plate is installed in the valve body; a stepped base is mounted in the middle of the middle partition plate; an upper mounting base is mounted on the valve body; a coil is mounted in the upper mounting base; a fixed iron core is mounted in the upper mounting base; a stepped valve core is mounted in the upper mounting base; the end, close to the fixed iron core, of the stepped valve core has magnetism; the lower end of the stepped valve core is arranged to be in a stepped shape;and the stepped valve core is right opposite to the stepped base and can be inserted into the stepped base. The electromagnetic valve is simple in structure, flexible in action, low in production cost and high in working reliability.

Description

technical field [0001] The invention belongs to the technical field of solenoid valves, in particular to a two-way solenoid valve. Background technique [0002] The two-way solenoid valves on the market generally have two valve discs, so the processing and assembly conditions of the two valve discs are extremely demanding, otherwise it is not conducive to the sealing of the medium, making the structure of the solenoid valve more complicated and increasing the production cost. In addition, if one of the two valve discs is damaged, the leakage of the medium will occur, resulting in unreliable work. [0003] There are also some technical solutions in the prior art, such as the Chinese patent with the application number CN201821343709.1, which includes electromagnetic components and valve body components.

[0002] Two-way solenoid valves on the market generally have two valve discs, so the processing and assembly conditions of the two valve discs are extremely demanding, otherwise it is not conducive to the sealing of the medium, making the structure of the solenoid valve more complicated and increasing the production cost

In addition, if one of the two valve discs is damaged, the leakage of the medium will occur, resulting in unreliable work.

[0003] There are also some technical solutions in the prior art, such as the Chinese patent with the application number CN201821343709.1, which includes electromagnetic components and valve body components. The above-mentioned electromagnetic valve can effectively prevent the backflow of the medium in the process of controlling the use of the fluid, but There is also the following problem. When controlling the flow, the solution can only adjust the diversion channel through the valve body in one direction, and cannot perform dual-channel adjustment and control according to the flow direction of the liquid. In addition, the solenoid valve is used for a long time. The internal sealing plug is prone to wear and aging, which will reduce the sealing effect of the solenoid valve, cause leakage, and reduce the reliability of the solenoid valve when it is working.
