Gas pressure reducing valve constant ratio reduced pressure principle, do you know?

Pneumatic valve gas pressure reducing valve set can be divided into gas pressure reducing valve than decompression principle is introduced by the medium oxygen nitrogen hydrogen pressure reducing valve, pressure reducing valve, relief valve, etc. Basic principle of the pressure reducing valve is to rely on port on the local resistance to reduce the water pressure in the valve, pneumatic valve pressure drop by connecting disc film or the scope of import and export pressure difference on both sides of the piston automatic adjustment. Constant ratio reduced pressure principle is to use the body floating in the piston of hydraulic ratio control, import and export side pressure ratio is inversely proportional to the import and export side piston area ratio, the pressure reducing valve work smooth and no vibration, pressure reducing valve production technology to further improve the country.
