The exhaust hole can balance air pressure, and the phenomenon that the sealing gasket cannot move upwards due to the fact that the air pressure in the mounting groove rises when the sealing gasket moves is avoided. The buffer spring in the structure can relieve the impact force of the sealing gasket on the top wall of the mounting groove. When the sealing gasket cannot recover to the original shape due to excessive compression, the buffer spring can drive the sealing gasket to move, so that the sealing gasket is effectively prevented from losing the effect of sealing the air outlet channel. The structure can effectively increase the sealing effect and the service life of the electromagnetic valve.
Because the groove opening at the bottom end of the mounting groove is provided with the protrusion, the bottom end surface of the sealing gasket can push against the protrusion. The bulge can prevent the sealing gasket from reducing the moving stroke of the movable iron core assembly under the thrust action of the buffer spring, so that the opening (closing) response time of the electromagnetic valve can be influenced.
Because the top end face of the movable iron core is provided with the buffer cushion, the movable iron core is in flexible top contact with the valve cover through the buffer cushion. The structure prevents the movable iron core from being rigidly pressed against the valve cover after moving. Thereby prolonging the service life and reducing the working noise.
