The use of the oxygen pressure pneumatic valve guide

the use of the reduced pressure pneumatic valve
, according to the different using requirements, oxygen pressure pneumatic valve has many specifications. Most of the highest inlet pressure for the minimum inlet pressure of not less than outlet pressure. Times.
and installing a vacuum pneumatic valve shall determine whether the connection specification is consistent with the sub cylinder and use the system. Reduced pressure pneumatic valve and cylinder connected by half spherical, screw the nut on the two perfectly match. Therefore, when use should remain on the surface of the two hemispheres is bright and clean, in order to ensure a good airtight effect. Before the installation can use high pressure gas blowing dust. When necessary, can be materials such as ptfe gasket.
, oxygen pressure pneumatic valve should be forbidden contact grease, in order to avoid fire accidents.
, stop work, should put a net the pressure-relief residual air in the pneumatic valve, then loosen the adjusting screw to avoid elastic element compression deformation for a long time.
pneumatic valve, decompression should avoid impact vibration, cannot be in contact with corrosive substances.

some other gas reduced pressure pneumatic valve gas, such as the permanent gas such as nitrogen, air, argon, oxygen pressure pneumatic valve can be used. But there are some gases, corrosive gases such as ammonia, requires special vacuum pneumatic valve. Common on the market there are nitrogen, air, hydrogen, ammonia, acetylene, propane, steam and other special pneumatic valve.
the reduced pressure of the pneumatic valve use method and matters needing attention and oxygen pressure pneumatic valve is basically the same. However, should also be pointed out that: vacuum pneumatic valve is generally not used in other gases. In order to prevent misuse, and some special vacuum pneumatic valve and the use of special connection between the cylinder. Such as hydrogen and propane adopt left thread, also known as a reverse thread, when installation should pay special attention to
