[0002] Gas cylinder sealing connectors use low-quality sealing materials, which are prone to airtight failure due to deformation and aging of the seals. The processing and assembly of the device are also common causes of airtight failure. Under high temperature and high pressure environments, the materials of the device will expand and contract, thereby affecting the airtightness. Failure to consider changes in temperature and pressure, and failure to make comprehensive considerations and sealing designs can easily lead to airtight failures due to these factors. Existing gas cylinder sealing connectors are prone to gas leakage when the sealing ring is damaged or fails. Therefore, a gas cylinder sealing connector with leak-proof function is proposed.
