Proportional type relief working principle of the pneumatic valve (3)

ratio type vacuum pneumatic valve working principle: the inlet pressure under the action of P, floating piston is pushed open, through the media. Due to the cross-sectional area on both ends of the piston pressure difference caused by different changed after pneumatic valve pressure, which is under the condition of the pipeline pressure, at the ends of the piston area ratio constitute the pneumatic valve pressure ratio before and after the pneumatic valve. No matter how change before the pneumatic valve pressure, pneumatic valve after static pressure and dynamic pressure can be reduced in proportion corresponding pressure value.
