[0002] A multi-stage sealing valve is a valve with a multi-sealing structure, which is designed to provide higher sealing performance and safety. This valve is usually used in situations where fluid leakage needs to be strictly controlled, such as chemical, petroleum, natural gas and other industries. Multi-stage sealing valves reduce the possibility of leakage by increasing the sealing level. Even if a sealing layer fails, the other sealing layers can still maintain the sealing state of the valve. Traditional multi-stage sealing valves are often fixed to the pipeline through multiple sets of bolts during use, which makes it inconvenient for staff to quickly install and disassemble them, thereby greatly reducing the installation and disassembly efficiency of multi-stage sealing valves.
