Example Embodiment

[0038] As an embodiment of the present invention, the step on the valve element 3 is provided with a sealing ring; the ring is located in the stepped side surface of the stepped lower end of the step 3 of the valve body; said ring 3 the valve body is located in step with the step seat between the two;

[0039] In operation, when the solenoid coil 411 in the power supply controller turns, pushing the spool 3 is inserted into the ladder after 2, step 3, the valve body a step on a stepped side surface of the seat ring provided with the step of the stepped seating step 2 step shaped side contact with each other, thereby enhancing the sealability between the valve body 3 and the stepped stepped seat, while the sealing ring can be guaranteed by the long time, resulting in a stepped valve body 3 between the stepped seat 2 badly worn, resulting in after the gap between them is increased, the sealing ring can still ensure the tightness between the two lines is qualified, effectively extend...

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. 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 followin...
