Industry Safety valves, also known as relief valves, play a protective role in the system, when the pressure exceeds the set value, it would be opened to release the pressure, so as to make sure the system avoides any accidents due to high pressure. Its opening and closing by the external force in a normally closed state, there should be no resistance at the outlet, to avoid the phenomenon of pressure. Generally used in toxic and corrosive media. For air and steam with safety, the adoption of non-closed safety valves.

Safety valves are protective devices for pressure vessels and other equipment. When the protected pressure vessel, the fluid pressure in the body reaches slightly higher than the normal working pressure of a specified value, the safety valve automatically opens, discharging part of the fluid, so that the pressure drops. When the pressure drops to a value slightly below the normal working pressure, the safety valve automatically closes, stops discharging fluid and maintains the seal. The function of safety valves is to prevent the medium pressure in the pipeline or device from exceeding the specified value, so as to achieve the purpose of safety protection. Safety valve is a kind of safety protection valve, its opening and closing parts are normally closed under the action of external force, when the equipment or pipeline medium pressure rises, exceeding the specified value automatically open, through the discharge of media to the outside of the system to prevent the pipeline or equipment medium pressure exceeds the specified value. Safety valve belongs to the automatic valve category, mainly used in boilers, pressure vessels and pipelines, control pressure does not exceed the prescribed value, for personal safety and equipment operation plays an important role in protecting.
