Network optimization information:

Engine solenoid valve is electromagnetic control of industrial equipment, is the control of fluid automation basic components. Belong to the actuator, not limited to hydraulic and pneumatic. The solenoid valve consists of an electromagnetic coil and a magnetic core, with one or more holes on the valve body. When the core is opened or closed, it causes fluid to flow through the valve body or to be cut off, changing the direction of the fluid.

Working principle of solenoid valve: the solenoid valve has a sealed cavity inside, different positions have through holes, each through hole to different tubing, valve in the middle of the cavity, two electromagnets on both sides. Automotive air conditioning solenoid valve coil which side is energized, the valve body will be attracted to which side. By controlling the movement of the valve body, it will stop or leak oil. Often open different oil discharge holes, and the oil inlet hole is often open, so the hydraulic oil will enter different drainage pipes, promote the cylinder piston, and then drive the piston rod. Control the current of an electromagnet to control mechanical motion.

According to the principle, solenoid valve can be divided into three types: direct drive, distributed drive and pilot drive. According to the structure can be divided into diaphragm drive and piston drive.
