The working principle of electromagnetic pneumatic valve flange interface

flange solenoid pneumatic valve is made up of pair of pneumatic valve and the main two parts of the guide type pneumatic valve open secondary pneumatic valve solenoid pneumatic valve. By vice of pneumatic valve to control the on-off of the pneumatic valve opening and closing. Depending on the power of switch state, can be divided into pneumatic valve and normally open normally closed electromagnetic solenoid pneumatic valve. Normally closed electromagnetic air valve, when power is often a pair of pneumatic valve mouth closed, and the main pneumatic valve is open circuit, when the signals into the guide solenoid coil, core activity by the electromagnetic effect on absorption vice pneumatic valve to open the mouth, the pneumatic valve pneumatic valve pressure inside the cup is rapidly disappearing, medium pressure will be the main pneumatic valve pneumatic valve on the cup, pneumatic valve, open the main working medium hard negotiable. But when signals disappear, activity core reset, vice pneumatic valve mouth, closed live working medium self balancing hole into the pneumatic valve cup, when pressure into balance, the Lord of pneumatic valve spring, pneumatic valve cup of self-respect and medium pressure pneumatic valve cup down, tightly sealed pneumatic valve mouth, pneumatic valve is closed. Normally open solenoid pneumatic valve, power, often by spring action, deputy pneumatic valve to open the mouth, the main circulation of pneumatic valve. When electrical signal into the vice of pneumatic valve coil, core activity by the electromagnetic effect, absorption, deputy pneumatic valve closed mouth, medium temperature solenoid pneumatic valve working medium through balance hole into the pneumatic valve inside the cup, when pressure into balance, the Lord of pneumatic valve spring, pneumatic valve cup of self-respect and medium pressure pneumatic valve cup down, tight sealing pneumatic valve mouth, pneumatic valve is closed. Disappeared when the main power pneumatic valve, electromagnetic force, deputy pneumatic valve is opened, the pressure in the main pneumatic valve cup is quickly disappearing, medium pressure will be the main pneumatic valve pneumatic valve on the cup, pneumatic valve, open the main medium circulation, pneumatic valve is open.
