Solenoid valve principle

Solenoid valve is used to control the flow of automation foundation components, belongs to the actuator. Solenoid valve is often used to control the hydraulic flow direction.

The factory is a mechanical device some by hydraulic cylinder control, so will be used solenoid valve. Solenoid valve  is in the closed cavity, its different position opened a hole, each holes are different pipeline to, is among the cavity, two sides are two pieces of solenoids, which the magnet coil electricity body will be attracted by the side of which, through the control valve body movement to block or leaks out different exhibit the holes, and oil import hole is often open, the hydraulic oil will enter each row of tubing, and then through the oil pressure to push oil cylinder piston, piston, piston rod and driving, driving the piston rod mechanical device move. So that through the control of the current you control the electromagnet mechanical movement.

Solenoid valve is mainly by the body and electromagnet component in pneumatic or hydraulic system  used to control the flow, the flow speed and hige. Open and close the valve by electromagnet promote rotary piston mobile manipulation, that control electromagnet is control solenoid valve. Solenoid valve general no auxiliary contacts, to use the logic relationship among relay transmission. Solenoid valve to use their structural position number and access number representation, "a" is a slide valve position, "tong" refers to the number of fluid channels, the commonly used two tee, two stone, three five, etc.dr
