Description

Technical Field

[0001] The utility model relates to the technical field of instrument protection equipment, in particular to a protection device for an oxygen cylinder pressure gauge. Background Art

[0002] Due to the strong oxidizing property of oxygen, a special pressure gauge is needed to measure oxygen pressure. The main difference between an oxygen pressure gauge and a general pressure gauge is that an oxygen pressure gauge is an oil-free gauge, that is, the final calibration of the pressure gauge is to calibrate the instrument pressure by gas or water, while an ordinary pressure gauge is calibrated by oil. Because oxygen cannot self-ignite but it can support combustion, oxygen will react violently with grease at a pressure above 2.462MPa, so oil is prohibited.

[0003] For the equipment carried on the ambulance, protective settings are made based on safety considerations, including the protection of the pressure gauge of the oxygen cylinder. However, the existing pressure gauge protection only covers the outer wall, and lacks protection for the instrument panel of the pressure gauge. When the ambulance is driving, it is often accelerated or braked suddenly, which can easily break the glass panel of the instrument panel. Not only will the pressure gauge be damaged and unable to read, but there is also a risk of high-pressure oxygen spraying out from the instrument panel. For this reason, we propose a protective device for the oxygen cylinder pressure gauge to solve the above problems. Utility Model Content
