Usually, there is a valve in the ventilation component, and the valve is opened by rotating the handwheel. To prevent hydrogen leakage, a sealing ring is set at the connection between the rotating shaft of the handwheel and the ventilation pipe. Since the rotating shaft needs to move frequently, after long-term use, the sealing ring will be damaged and leakage will occur. Summary of the Invention
