Solenoid valve Encyclopedia

Electromagnetic valve is an electromagnetic control industrial equipment, is used to control the automation of the basic components of the fluid, is an actuator, not limited to hydraulic, pneumatic. Adjust the direction, flow, speed and other parameters of the medium in the industrial control system. Solenoid valve can cooperate with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed. There are many kinds of solenoid valves, different solenoid valves play different roles in the control system, the most commonly used are one-way valve, safety valve, directional control valve, speed control valve, etc..
Working principle
Solenoid valve in a closed chamber, in different locations to open a hole, each hole connecting different pipe, cavity intermediate piston, both sides are two electromagnets, which face the magnet coils body will be attracted to which side, to open or close the oil drain hole through different control valve moves, and the oil inlet hole Shichang opened, hydraulic oil will enter the drain pipes of different, then the oil pressure to push the piston cylinder, piston and piston rod, the piston rod drives the mechanical device. Thus, the mechanical motion is controlled by controlling the current breaking of the electromagnet.
