01. InstallationOxygen pressure regulatorPreviously, it was necessary to slightly open the valve of the gas cylinder to blow down dirt and prevent dust and moisture from entering the pressure regulator before installing it. When opening the gas cylinder valve, the operator should not stand in front of the valve outlet to prevent high-pressure gas from suddenly rushing out and injuring people.

02. The pressure regulator screw should be loosened before opening the gas cylinder valve. When opening the gas cylinder valve, it should be done slowly without excessive force to prevent damage to the pressure regulator and high-pressure gauge caused by high-pressure gas.

03. After opening the gas cylinder valve, check whether there is any air leakage in various parts and whether the pressure gauge is working properly. After the inspection is completed, connect the hose.

When adjusting the working pressure, the pressure regulating screw should be slowly rotated to prevent high-pressure gas from damaging the diaphragm or the low-pressure gauge.

05. The pressure reducer must not be contaminated with grease. If there is grease, it must be wiped clean before use.

06. If the pressure reducer freezes during use, it should be thawed with hot water or steam. Do not use fire for baking.

When stopping work, the bottle valve should be closed and the gas in the pressure reducer should be slowly released, and the pressure regulating spring should be in a free state.

08. The pressure regulator must be checked regularly, and the pressure gauge must be calibrated regularly to ensure reliable pressure regulation and accurate readings.

09. Oxygen pressure reducers and acetylene pressure reducers should not be interchanged.

10. The working pressure of acetylene pressure reducer should not exceed 0.1 MPa.
