1. Before installing the pressure reducer, open the cylinder valve to blow down dirt to prevent dust and moisture from entering the regulator and then install the regulator. When the cylinder valve is opened, the operator should not stand in front of the outlet of the bottle valve to prevent the high-pressure gas from bursting out to hurt people.
2. The pressure regulator screw should be loosened before opening the cylinder valve. When opening the cylinder valve, do not use excessive force to prevent the high pressure gas from damaging the pressure reducer and the high pressure meter.
3. After opening the cylinder valve, check whether there are any air leaks in the various parts and whether the pressure gauge is working properly. After the check is complete, connect the hose.
4. When adjusting the working pressure, slowly turn the regulator screw to prevent the high-pressure gas from damaging the diaphragm or damaging the low-pressure meter.
5, pressure reducer must not be contaminated with grease, if any grease must be controlled before use.
6. If a pressure reducer freezes during use, apply hot water or steam to thaw. Do not bake with fire.
7. When the work is stopped, the bottle valve should be closed, and the gas in the pressure reducer should be slowly exhausted, and the pressure regulating spring should be in a free state.
8. The pressure reducer must be inspected regularly and the pressure gauge must be regularly calibrated to ensure reliable pressure regulation and accurate readings.
9, oxygen regulator and acetylene reducer are not interchangeable with each other.
10. The working pressure of acetylene pressure reducer should not exceed 0.1 MPa.
In particular, note that oxygen regulators and oxygen cylinders must be banned from oil:
If grease is applied, when the oxygen cylinder valve is opened, oxygen is rapidly sprayed through the bottle mouth. The high-speed airflow will generate frictional heat with the grease, which will increase the temperature and promote the oxidation reaction. At the same time, the grease will be higher in pure pressure. Oxygen oxidizes faster in the environment, so the oil that dipped on the oxygen hemispherical mouth or on the reducer will burn, and even cause an explosion.
