Instruction manual for pressure reducer
usepressure reducerThe following rules should be followed:
(1) The action of releasing gas from the oxygen cylinder or opening the pressure reducer must be slow. If the valve opening speed is too fast, the temperature of the gas in the working part of the pressure reducer will greatly increase due to adiabatic compression, which may cause organic materials such as rubber packing and rubber film fiber pads to catch fire and burn out, and may also cause the pressure reducer to burn out. In addition, static sparks generated by rapid deflation and oil stains on the pressure regulator can also cause ignition, burning, and damage to the pressure regulator components.
（2）pressure reducerPrecautions before installation and when opening the gas cylinder valve: Before installing the pressure reducer, the valve should be slightly opened to blow away dirt and prevent dust and moisture from entering the pressure reducer. When opening the gas cylinder valve, the outlet of the valve should not be aimed at the operator or others to prevent high-pressure gas from suddenly rushing out and injuring people. The joint between the outlet of the pressure reducer and the gas rubber pipe must be tightened with a wire or clamp that has been overheated; Prevent the risk of detachment after air supply.
（3）pressure reducerPrecautions during loading and unloading and work: When loading and unloading the pressure reducer, attention must be paid to preventing the thread of the pipe joint from slipping, so as to avoid improper rotation and injection. During the work process, it is necessary to pay attention to observing the pressure value on the work pressure gauge. When stopping work, first loosen the pressure regulating screw of the pressure reducer, then close the oxygen cylinder valve, and slowly exhaust the gas inside the pressure reducer. This can protect the spring and pressure reducing valve from damage. After the work is completed, the pressure regulator should be removed from the gas cylinder and stored properly.
(4) The pressure regulator must be regularly calibrated, and the pressure gauge must be inspected regularly. This is done to ensure the reliability of pressure regulation and the accuracy of pressure gauge readings. If any air leakage or malfunction of the pressure gauge needle is found during use, it should be repaired in a timely manner.
（5）pressure reducerFreeze processing. If the pressure regulator freezes during use, use hot water or steam to thaw it, and never use flames or red iron to bake it. After the pressure regulator is heated, any residual moisture must be blown off.
(6) The pressure regulator must be kept clean. The pressure reducer must not be contaminated with grease or dirt. If there is grease, it must be wiped clean before use.
(7) Pressure reducers and gauges for various gases must not be interchanged, such as pressure reducers for oxygen, which cannot be used in systems such as acetylene and petroleum gas.
