The working principle of gas solenoid pneumatic valve

the working principle of gas solenoid pneumatic valve:
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 pneumatic valve, power outages, often by weight of armature and seal spring and medium pressure pneumatic valve mouth sealed, cutting off is accused of medium flow.

the electromagnetic coil after electrify, overcoming armature self-respect and pneumatic valve seal spring core, medium pressure forces will activities, together with the pneumatic valve gasket on the suction mouth, open the pneumatic valve mouth, was charged with medium negotiable.

power normally open solenoid pneumatic valve, electromagnetic suction is equal to zero, in the spring under the action of moving iron core, pneumatic valve lever up and, pneumatic valve is opened, medium circulation. When electricity due to the suction effect moving iron core down, promote the pneumatic valve stem, pneumatic valve closed, medium is broken.

solenoid pneumatic valve nature of work: general circulation coefficient is very small, and the work pressure difference is very small. Such as average diameter than the diameter of the solenoid pneumatic valve flow coefficient of the electric pneumatic valve ball. Electromagnetic pneumatic valve driven by electromagnetic coil, more easily damaged by voltage surge. Equivalent to the role of the switch is on or off a role.

gas solenoid pneumatic valve is suitable for city gas, liquefied petroleum gas, natural gas and other gas pipeline for two type on-off switch for automatic control of actuators. It is widely used in textile, dyeing of gas heat styling, bulb and glass kiln heating gas heating control system and other industries. Structural principles:



this solenoid pneumatic valve has simple structure, large flow, long life, safe and reliable, etc.

gas pneumatic valves direct-acting electromagnetic type low voltage solenoid pneumatic valve. On-off control medium of pneumatic valve seal mouth, through the pneumatic valve rod directly connected to the core activity.

DN diameter above the gas solenoid pneumatic valve, should adopt the secondary structure of pneumatic valve open. （ The working principle of gas solenoid pneumatic valve)
