Integral increase of solenoid valve exhaust hole.

1, the size of the solenoid valve gas is related to the gas pressure and the size of the solenoid valve.

2. In the pneumatic system, when the gas pressure is determined, the gas output of the valve cannot be increased by increasing the gas pressure.

There is a closed cavity in the solenoid valve, and there are through holes in different positions. Each hole is connected with a different oil pipe. There is a piston in the middle of the cavity and two electromagnets on both sides. When the electromagnetic coil on which side is energized, the valve body will be attracted to which side. By controlling the movement of the valve body, different oil discharge holes will be opened or closed, while the oil inlet hole is always open. Hydraulic oil will enter different oil discharge pipes, and then the piston of the oil cylinder is pushed by the oil pressure, which in turn drives the piston rod, which drives the mechanical device. In this way, the mechanical movement is controlled by controlling the on-off of the electromagnet.
