Piston type steam solenoid pneumatic valve working principle

the solenoid pneumatic valve piston steam to step-by-step actions directly guiding type pneumatic valve, electromagnetic power according to the open and closed status of different, can be divided into often closed solenoid pneumatic valve and often open solenoid pneumatic valve. After pneumatic valve, normally closed electromagnetic coil current and armature in under the action of electromagnetic force to drive the pneumatic valve pneumatic valve plug, the pneumatic valve pneumatic valve cup of fluid by the vice of pneumatic valve outflow, reduced the effects in the main pneumatic valve pneumatic valve pressure on the cup, when the main pneumatic valve pneumatic valve cup pressure was reduced to a certain value, the armature drives the main pneumatic valve pneumatic valve cup, and use the pressure difference and make the main pneumatic valve pneumatic valve cup opening, medium circulation. Coil after power, the electromagnetic force disappears, armature due to falling weight reduction. At the same time rely on the media pressure, main pneumatic valve to close and close.
piston pneumatic valve, normally open electromagnetic coil current due to the suction effect, after moving iron core down, the vice pneumatic valve pneumatic valve plug pressure, pneumatic valve closed, the pneumatic valve pneumatic valve pressure rise within cup, when the pressure rises to a certain value, the main pneumatic valve pneumatic valve cup of fluctuation pressure difference, due to the electromagnetic effect, moving iron core loss of the pneumatic valve pneumatic valve cup, the main pneumatic valve pneumatic clamping seat, pneumatic valve shut off. Coil power, electromagnetic suction is zero, pair of pneumatic valve pneumatic valve plug and the iron core is due to the spring lift, deputy pneumatic valve opens, the pneumatic valve pneumatic valve cup of fluid by the vice of pneumatic valve outflow, reducing the role in the main pneumatic valve pneumatic valve pressure on the cup, when the main pneumatic valve pneumatic valve cup pressure was reduced to a certain value, the use of differential pressure push the main pneumatic valve pneumatic valve cup, the main pneumatic valve open, medium circulation.
