Explosion-proof two-position three-way direct-acting precision electromagnetic valve

Abstract

The utility model provides a kind of explosion-proof two-position three-way direct-acting type precision solenoid valve, the solenoid valve includes end cover, first valve body, sealing block and second valve body, the inside of coil assembly is sequentially provided with static iron core and moving iron core from top to bottom, limit piece is arranged in second valve body;Moving iron core passes through limit piece, and end portion is provided with sealing assembly;When coil is energized, moving iron core can be driven to move towards the direction close to static iron core, to drive sealing assembly to move towards the direction close to limit piece, so that inlet flow passage and outlet flow passage are communicated, realize valve opening;Sealing assembly includes vulcanization formed metal valve core and sealing element, and the bonding surface shear strength is high, not only can improve the overall structural stability of sealing assembly, sealing reliability and service life;Meanwhile, in the process that solenoid valve opens and closes, the overall of sealing element participates in deformation, force distribution is on entire sealing element, avoid long-term local deformation and lead to sealing element failure.
