The safety valve is a kind of safety protection valve, whose opening and closing parts are normally closed under the action of external forceThe ConduitInmediumWhen the pressure increases, it opens automatically when the pressure exceeds the specified value, and the pressure of the medium in the pipeline or equipment exceeds the specified value by releasing the medium outside the system. Safety valve belongs toAutomatic valveClass, mainly used inboiler、pressureContainer andThe ConduitThe control pressure does not exceed the specified value, and plays an important role in the protection of personal safety and equipment operation.
Safety valves are important safety accessories for pressure vessels and other pressure equipment. Its reliability and performance are directly related to the safety of equipment and people, and closely related to energy conservation and environmental protection. And some users and design departments in the selection, always choose the wrong type. Therefore, the selection of safety valve is analyzed in this paper.
Safety valve，Pressure relief valve，It's based on the pressure systemWorking pressureAutomatic opening and closing, generally installed in the closed system equipment or pipeline protection system security. When equipment orThe ConduitWhen the internal pressure or temperature exceeds the setting pressure of the safety valve, the pressure or temperature can be automatically opened to ensure the inside of the equipment and the pipelinemediumPressure (temperature) under setting pressure (temperature), protection equipment and pipeline work normally, to prevent accidents, reduce losses.
The safety valve plays a safety role in the system. When the system pressure exceeds the specified value, the safety valve is opened and a part of the gas in the system is opened/Fluid flows into the atmosphere/Outside the pipeline, the pressure of the system does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.A21H-16T、A47H、A27W-10T4Branch,A27W-10T6Branch,A27W-10T1Inch,A27W-10T1.2Inch,A27W-10T1.5Inch,A28X-16T 9kg4Branch,A28X-16T 9kg6Branch,A28X-16T 9kg1Inch,A28X-16T 9kg1.2Inch,A28X-16T 10kg4Branch,A28X-16T 9kg1.5Inch,A28X-16T 10kg6Branch,A28X-16T 12kg4Branch,A28X-16T 12kg6Branch,A28X-16T 12kg1Inch,A21W-16T 30kg4branchA21W-16T 30kg6Branch,A21W-16T 30kg1Inch,A42Y、VF-31、VF-31
