Introduction to the working principle of explosion-proof solenoid valve

　　Explosion-proof solenoid valve is an automatic basic component used to control fluid, which belongs to the actuator; it is not limited to hydraulic and pneumatic. Solenoid valves are used to control the direction of hydraulic flow. The mechanical devices of valve actuator factories are generally controlled by hydraulic steel, so solenoid valves are used.

working principle

The explosion-proof solenoid valve has a closed cavity with through holes at different positions. Each hole leads to a different tubing. In the middle of the cavity is the valve. On both sides are two electromagnets. Which side of the magnet coil energizes the valve body Where will it be attracted? By controlling the movement of the valve body to block or leak out different drain holes, the oil inlet hole of the liquid level gauge is normally open, and the hydraulic oil will enter different drain pipes and then pass the oil The pressure to push the oil-gang piston, the piston drives the piston rod, and the piston rod drives the mechanical device to move. In this way, the mechanical movement is controlled by controlling the current of the electromagnet.

Normally closed: When the coil is energized, the electromagnet core pulls in, the pressure relief hole opens, and the main piston is pushed by the medium pressure.

Open the main valve port and the medium flows.

When the coil is de-energized, the main valve port is closed and the medium is cut off.

Normally open: When the coil is energized, the solenoid core is closed, the pressure relief hole is closed, and the main piston is pushed by the medium pressure.

Close the main valve port, and the solenoid valve media is cut off.

When the coil is de-energized, the main valve port opens and the medium flows.
