Problems solved by technology

Subsequent temperature drop or when the fluid flow is exhausted, the thermally expanded resin valve body 230 begins to shrink, causing loosening of screws during assembly, which in turn causes leakage around the isolation diaphragm 210
[0006] Therefore, there is a need to provide a solenoid valve with an isolating diaphragm structure, which can overcome the above-mentioned situation of easy leakage around the isolating diaphragm.

Embodiment Construction

[0017] Such as figure 2 As shown, the diaphragm structure two-way solenoid valve 100 of the present invention includes a valve body 10, an electromagnetic drive part 21 installed on the valve body 10, an electromagnetic coil 22 installed on the electromagnetic drive part 21, and an electromagnetic coil 22 installed on the valve body 10 and the solenoid valve. The diaphragm 30 is separated between the driving parts 21 , and a sealing ring 40 is arranged between the electromagnetic driving part 21 and the valve body 10 . In the present invention, the electromagnetic driving part 21 and the valve body 10 are assembled and fixed by screws. Furthermore, the sealing ring 40 is disposed between the electromagnetic driving part 21 and the isolation diaphragm 30 . The sealing ring 40 is an O-ring. The part of the valve body 10 in contact with the liquid is made of anti-corrosion material. The anti-corrosion material is an anti-corrosion resin material.

Abstract

The invention discloses a two-way electromagnetic valve with a diaphragm structure, comprising a valve body, an electromagnetic driving part, an electromagnetic coil and an isolation diaphragm. The electromagnetic driving part is arranged on the valve body; the electromagnetic coil is arranged on the electromagnetic driving part; the isolation diaphragm is arranged between the valve body and the electromagnetic driving part; and a sealing ring is arranged between the electromagnetic driving part and the valve body. As the sealing ring is arranged between the electromagnetic driving part and the valve body, when high-temperature liquid flows through the two-way electromagnetic vale in the diaphragm structure, the leakage of the two-way electromagnetic vale with the diaphragm structure, which is caused by thermal expansion, is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of a two-way solenoid valve with a diaphragm structure, in particular to a sealing structure of a two-way solenoid valve with a diaphragm structure. Background technique [0002] Solenoid valves use energized coils to generate electromagnetic force to drive the movement of the isolation diaphragm to open or close the valve and change the flow direction of the fluid, so as to achieve the purpose of the actuator to change the direction of fluid movement. It has many types and wide uses, and is the most important type of control valve. Among them, the isolation diaphragm type two-way reversing solenoid valve is widely used in the field of medical and environmental analysis and detection, as well as in the field of life science. It includes a valve body with a fluid inlet and outlet, a valve seat, a cylindrical shell-type coil drive part with a built-in energized coil, and a circular isolation diaphragm made of...
