[0002] A gas pressure reducer is a device that reduces the pressure of high-pressure oxygen gas stored in an oxygen cylinder to the low-pressure oxygen required for gas welding. Since the pressure in the cylinder is relatively high, while the pressure required for gas welding, gas cutting and the point of use is relatively low, a pressure reducer is needed to reduce the higher-pressure gas stored in the cylinder to low-pressure gas, and the required working pressure should be kept stable from beginning to end.

When using the existing calibration device, the air inlet pipe and the air outlet pipe need to be fixedly installed on the gas pressure reducer, which can easily damage the original sealing state of the calibration device, resulting in leakage and other problems when the gas pressure reducer is in use.
