Gate valve is one of the most widely used valves in various fluid transportation projects. Traditional gate valves generally have phenomena such as easy fluid leakage and serious corrosion of internal parts. In the ordinary soft seal gate valves on the market, the stem shaft seal is easy to leak, and it is impossible to replace the sealing ring under continuous water and at any opening degree.
