Oxygen use method 1, according to the requirement of the pressure reducing valve is different, there are many specifications oxygen pressure reducing valve. Most of the highest inlet pressure for the minimum inlet pressure not less than 2 of outlet pressure. 5 times. 2, installing a pressure reducing valve shall determine whether the connection specification is consistent with the sub cylinder and use the system. Pressure reducing Industrial Valves and cylinder adopt the half spherical connection, 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. 3, oxygen pressure reducing valve should be forbidden contact grease, in order to avoid fire accidents. 4, stop work, pressure reducing Industrial Valves should be residual air in the net, then loosen the adjusting screw to avoid elastic element compression deformation for a long time. 5, pressure reducing valve should avoid impact vibration, cannot be in contact with corrosive substances. Other gas pressure reducing valve, some gases, such as the permanent gas such as nitrogen, air, argon, oxygen pressure reducing valve can be used. But there are some gases, corrosive gases such as ammonia, requires special pressure reducing valve. Common on the market there are nitrogen, air, hydrogen, ammonia, acetylene, propane, steam and other special pressure reducing valve. Use method and matters needing attention of the pressure reducing valve and oxygen pressure reducing valve are basically the same. However, should also be pointed out that: special pressure reducing Industrial Valves is generally not to be used for other gases. In order to prevent misuse, and some special pressure reducing valve between the cylinder and the use of special connectors. Such as hydrogen and propane adopt left thread, also known as a reverse thread, when installation should pay special attention to.
