Oxygen valve use 1, according to the different requirements, oxygen valve has many specifications. The maximum import pressure is mostly the minimum import pressure is not less than 2.5 times the outlet pressure. 2, the installation of the valve should be determined whether the connection specifications and the cylinder and the use of the system connector consistent. Pressure reducing valve and cylinder with hemispherical connection, by tightening the nut so that the two completely match. Therefore, the use of the two hemispherical surfaces should be kept clean to ensure a good airtight effect. Use high-pressure gas to blow off the dust before installation. If necessary, PTFE and other materials can also be used for gaskets. 3, oxygen valve should be prohibited contact with grease, so as to avoid fire accidents. 4, stop working, the pressure relief valve should be more than net release, and then loosen the adjustment screw to prevent long-term compression of elastic deformation. 5, pressure relief valve should be to avoid vibration, not in contact with corrosive substances. Other gas pressure relief valve Some gases, such as nitrogen, air, argon and other permanent gases, you can use oxygen valve. But there are some gases, such as ammonia and other corrosive gases, you need a special pressure relief valve. Common on the market are nitrogen, air, hydrogen, ammonia, acetylene, propane, steam and other special pressure relief valve. The use of these valves and precautions and oxygen valve is basically the same. However, it should also be noted that special pressure relief valves are generally not used for other gases. In order to prevent misuse, some special pressure reducing valve with a special connection between the cylinder. For example, hydrogen and propane are used left-tooth thread, also known as reverse thread, installation should pay special attention.
