Regulating working principle of the pneumatic valve is what

regulating pneumatic valve profile
in the transition process can be used to decrease the pressure rise, in the case of accident can discharge the pneumatic valve pressure pipe in the water. Pneumatic valve type

adjustment according to the purpose and function, main parameters, pressure, medium temperature, special purpose ( Namely, special, special pneumatic valve, drive in the form of energy, the structure and the classification, one of the most commonly used classification is according to the structure of regulating pneumatic valve can be divided into nine categories, for straight travel, for Angle.
regulating working principle of the pneumatic valve
basic can be reduced pressure pneumatic valve, pneumatic valve regulating pressure pneumatic valve working principle is as follows:
high pressure medium through a small hole in a relatively large cavity filling realize the decompression, is actually by intercepting the reduced pressure, both sides of the diaphragm or piston side is out of the mouth, is human to stress, and pore size of pneumatic control valve stem and diaphragm ( Piston is linked together, such as long as give a fixed pressure, so the oral cavity pressure is equal to the pressure, the think of the given pressure can have a spring or air or hydraulic source to provide.
