The working principle of electromagnetic pneumatic valve what kind is it? What are those

solenoid pneumatic valve is used to control the direction of the fluid automation components, belonging to the actuator; Above are normally used for mechanical control and industrial pneumatic valve, to control the direction of the medium, so as to achieve control of the pneumatic valve switch.


mixer works
has sealed cavity, open a hole in different position, every 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 body to blocked or leakage of different discharge of oil hole, and the 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. So that by controlling the electric current of the electromagnet to control the mechanical movement.

pieces classification. In principle can be divided into three categories:
( ） Direct acting solenoid pneumatic valve:
principle: electricity, electromagnetic force open the pilot hole, the chamber pressure drops rapidly, in closed form around the high low differential pressure, fluid pressure push close up, pneumatic valve open; Power off, the spring force to close the guide hole, inlet pressure chamber through the bypass hole quickly shut in pneumatic valve using a form around on high pressure difference, fluid pressure push close move down, close the pneumatic valve.
characteristics: in a vacuum, negative pressure, can work properly when the zero pressure, but size is generally not more than the mm.
( ） Straight acting distribution:
features: on the zero differential pressure or vacuum and high pressure, to * action, but power is larger, requirements must be installed level.
( ） Guiding type:
features: high fluid pressure range limit, can be arbitrary installation ( Need to customize) But fluid differential pressure conditions must be met.
. From the pneumatic valve structure and material of different on the principle of distinction, is divided into six branches small classes:
diaphragm structure, step by step of moving heavy piece of membrane structure, the structure, the forerunner in straight moving piston structure, step by step piston structure, the forerunner of moving piston structure.
