Bellows safety valves are suitable for equipment or pipelines with unstable back pressure or toxic or corrosive media at operating temperatures ≤ 200 ℃. They serve as overpressure protection devices and provide safety protection in the system. The working principle is: when the system pressure exceeds the specified value, the safety valve opens, and a part of the gas in the system is discharged into the atmosphere, ensuring that the system pressure does not exceed the allowable value, thereby ensuring that accidents do not occur due to excessive pressure.

Structure and principle of corrugated pipe safety valve

Bellows safety valves are used as overpressure protection devices on equipment or pipelines with unstable back pressure or toxic or corrosive media. Bellows can eliminate the impact of back pressure fluctuations on valve performance and also protect springs and other internal components from corrosion by the medium. And it can effectively prevent media leakage. Other safety valves are the same as ordinary spring safety valves.
