What Is Principle Of Solenoid Valve Body?

Dec. 20, 2018

There are closed chambers in the Solenoid Valve Body. There are through holes in different positions. Each hole is connected with different oil pipes. The middle part of the cavity is a piston. On both sides are two electromagnets. Which side of the magnet coil is energized? Side, by controlling the movement of the valve body to open or close different oil drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil drain pipes, and then the pressure of the oil pushes the piston of the oil cylinder, and the piston Drive the piston rod, and the piston rod drives the mechanical device. This controls the mechanical motion by controlling the current through and off of the electromagnet.

Principle: It is a combination of direct motion and pilot type. When there is no pressure difference between the inlet and the outlet, after energization, the electromagnetic force directly lifts the pilot small valve and the main valve closing member upward, and the OEM Solenoid Valve Body opens. When the inlet and outlet reach the starting pressure difference, after the energization, the electromagnetic force leads the small valve, the pressure of the lower chamber of the main valve rises, and the pressure of the upper chamber drops, so that the main valve is pushed upward by the pressure difference; when the power is off, the pilot valve uses the spring The force or medium pressure pushes the closure and moves down to close the valve.

Features: It can be operated at zero pressure difference or vacuum or high pressure, but the power is large, and it must be installed horizontally.
