Problems solved by technology

Conventional solenoid valves are generally only suitable for clean media. If the media contains fine impurities, it is easy for the valve to close tightly or the moving parts to be stuck, especially when the gas circulating through the gas solenoid valve contains dust and particles, etc. When there are impurities, the impurities will adhere to the inside of the gas solenoid valve, which will cause the moving parts to be blocked during the movement, which will affect the service life and working efficiency of the gas solenoid valve

Abstract

The invention discloses a medium isolation type gas electromagnetic valve used for isolating solid impurities in gas. The medium isolation type gas electromagnetic valve comprises a valve body assembly, a movable iron core assembly, a fixed iron core assembly and a wire wrapping shell assembly, wherein the valve body assembly is connected with the wire wrapping shell assembly through a valve deck;the movable iron core assembly is partially arranged in the valve body assembly; the fixed iron core assembly is arranged in the wire wrapping shell assembly; and the movable iron core assembly is partially arranged in a fixed iron core cavity of the fixed iron core assembly and driven by the wire wrapping shell assembly to slide relative to the fixed iron core assembly. According to the medium isolation type gas electromagnetic valve, the solid impurities in the circulating gas are isolated through an isolation membrane, and therefore the impurities cannot be attached to the interior of thegas electromagnetic valve, a movement device cannot be blocked in the movement process, the service life of the gas electromagnetic valve is prolonged, and the work efficiency of the gas electromagnetic valve is improved.

Description

technical field [0001] The invention belongs to the technical field of gas solenoid valves, and in particular relates to a medium isolation type gas solenoid valve. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic. It is an automatic basic component used to control fluid. It belongs to actuator and is used to adjust the direction, flow, speed and other parameters of medium in industrial control system. Solenoid valves can cooperate with different circuits to achieve the expected control, and the control accuracy and flexibility can be guaranteed. Conventional solenoid valves are generally only suitable for clean media. If the media contains fine impurities, it is easy for the valve to close tightly or the moving parts to be stuck, especially when the gas circulating through the gas solenoid valve contains dust and particles, etc. When the impurities are removed, the impurities will adhere to the inside of the gas solenoid...
