Elektromanyetik valf montaj makinesinin çalışma prensibi

Doğrudan etkili elektrik tonu: Güç uygulandığında, elektromanyetik bobin elektrik üretir ve doğrudan valf çekirdeğini çekerek çekirdeğin kaymasına neden olur. Elektrik kesildiğinde elektromanyetik kuvvet ortadan kalkar ve valf göbeği sarı yay sayesinde sıfırlanır.
Distributed direct acting solenoid valve: It is a combination of direct acting and pilot operated principles. Normally closed - when there is no pressure difference between the inlet and outlet, the electromagnetic force directly opens the pilot hole after being energized, and the piston of the main valve is lifted upwards in sequence to open the valve; When the starting pressure difference between the inlet and outlet is reached, after being energized, the electromagnetic force first opens the pilot hole, causing the pressure in the upper chamber of the main valve piston to decrease, thereby utilizing the pressure difference and electromagnetic force to pull the main piston and open the valve port; When the power is cut off, the pilot hole is closed by spring reset, and the upper chamber of the main piston is pressurized, pushing the main piston to move downwards, and the valve is closed. Normally open and normally closed are the opposite.
