The working principle of cast steel solenoid pneumatic valve

cast steel solenoid pneumatic valve applicable to steam for heating medium, automatic temperature control of actuators. For steam heater, radiator, dryer steam equipment and all kinds of temperature control instrument, such as steam setting machine, steam engine, damping machine such as complete sets of equipment of boiler steam pipelines for two type automatic control and remote control.

cast steel solenoid pneumatic valve is a pair of pneumatic valve and the main two parts of pneumatic valve guiding type 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.

in the cast steel solenoid pneumatic valve closed cavity, in a different location to open a hole, each hole leads to different tubing, cavity pneumatic valve is among, both sides are two electromagnets, which face the magnet coil electricity pneumatic valve will be attracted to which side, by controlling the movement of the pneumatic valve to block or leak hole, different discharge of oil and oil hole is always open, hydraulic fluid will enter the different oil drain, and then through the oil pressure to push the cylinder piston, piston drives the piston rod, piston rod drive mechanism. This flow of electricity by controlling the electromagnet fault controls the mechanical movement.
