Chuanna Hydraulic Editor would like to introduce the working principle of solenoid valves to everyone!
The solenoid valve has a sealed chamber with through holes at different positions, each connected to a different oil pipe. The middle of the chamber is a piston, and there are two electromagnets on both sides. The valve body will be attracted to which side when the magnet coil on the other side is energized. By controlling the movement of the valve body, different oil discharge holes can be opened or closed. The oil inlet hole is normally open, and hydraulic oil will enter different oil discharge pipes. Then, the pressure of the oil will push the piston of the oil cylinder, which in turn drives the piston rod, which drives the mechanical device. In this way, the mechanical motion is controlled by controlling the current on and off of the electromagnet.
