The working principle of the electric discharge pneumatic valve

electric discharge pneumatic valve because of its compact structure, small volume, light quality, sealed performance is superior to wait for a characteristic, is now widely used in chemical, petroleum, pharmaceutical, light industry, such as automatic control, has the market the user's attention and love.
electric discharge pneumatic valve working principle:
directly depend on the effects of the force to help the medium pressure in the pneumatic disc of the mechanical load on the seal, the mechanical load acting in pneumatic disc is mainly from the compression spring, this is almost fixed mechanical load. Although for compression spring, loading of pneumatic valve can be adjust the spring force to achieve good sealing, but the seal differential pressure must be strong enough, to ensure enough sealing force, thus the normal operation of pneumatic valve to seal. Seal differential pressure should also be smaller than the opening and closing pressure difference, in order to ensure open and flexible.
