The working principle of the 220V solenoid valve is that there is a closed cavity in the solenoid valve, and there are through holes in different positions. Each hole leads to a different oil pipe. There is a valve in the middle of the cavity, and two electromagnets on both sides. The energized valve body will be attracted to which side, and the movement of the valve body is controlled to block or leak different oil discharge holes, and the oil inlet hole is normally open, and the hydraulic oil will enter different oil discharge pipes, and then pass through The pressure of the oil pushes the piston of the oil, 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 electric current of the electromagnet.
