Working principle of 531 solenoid valve, the difference between 531 solenoid valve and 551

531 solenoid valve How it works

ASCO531 series is a pilot-operated solenoid valve that uses the air source from the air inlet to push the sliding of the valve core, and controls the force entering the slide valve (i.e. valve core) through the force generated by electromagnetic induction. The air source, thereby controlling the sliding of the valve core, is not the force generated by electromagnetic induction that directly controls the slide valve;

The air inlet 1 is connected to the air source, the air outlet 2 is connected to the lower chamber of the valve cylinder, and the air outlet 4 is connected to the upper chamber of the valve cylinder.< a href="https://www.diancifa.cc/diancifa/" target="_blank" title="Solenoid Valve">Solenoid valveWhen the solenoid valve loses power, the valve is in the open state;when the solenoid valve is powered on, the valve is in the closed state;

Solenoid valve power-off state:

When the solenoid valve is de-energized, the air inlet 1 is connected to the air outlet 2, the air outlet 4 is connected to the exhaust hole 5, the piston F is kept in the left position under the elastic force of the spring A in the valve, and the air inlet 1 is The air source is connected to the C air inlet in the chamber through the red arrow hole in the picture below (the air inlet is an independent hole and is only connected to the air inlet 1 and not to the air outlet 4);

Iron core E is under the action of elastic force Hold up the air inlet C and block the air inlet C;

Solenoid valve power status:

When the solenoid valve is energized, the iron core E moves to the left against the elastic force of the spring, and the air inlet C begins Intake air, and push piston F to move to the right against the elastic force of spring A under the pressure of the air source. The air inlet 1 is connected to the air outlet 4, the air outlet 2 is connected to the exhaust hole 3, and 4 is connected to the valvePrevious:What does the gas solenoid valve look like when it is open?
