Description
Technical Field
[0001] This utility model relates to a protective cap for fixing gas cylinders, belonging to the field of gas cylinder fixing technology. Background Technology
[0002] Gas cylinders are mobile pressure vessels used in many places, such as engineering construction and oil and gas production sites. High-pressure gas cylinders such as oxygen cylinders, acetylene cylinders, and positive pressure breathing apparatus cylinders are widely used. When using gas cylinders, a cap is needed on top to protect the cylinder valve. However, the caps of some existing gas cylinders are too short, which provides poor protection for the cylinder valve. The cylinder valve is easily damaged by impact. On the other hand, some large fixed caps allow the cylinder valve to be adjusted directly through the gaps in the cap, which poses a possibility of misoperation and is inconvenient for workers to use.
