What is the difference between safety valve and relief valve in structure
Safety valve is an important safety accessory on boilers, pressure vessels and other pressure equipment. The reliability and performance of the device are directly related to the safety of the device and human body, and are closely related to energy conservation and environmental protection.
Safety valve, an automatic pressure relief device driven by the static pressure of the medium in front of the valve. It is characterized by a full opening action with sudden opening. Used of gas or steam
Relief valve, also known as relief valve an automatic pressure relief device driven by the static pressure of the medium in front of the valve. It opens proportionally as the pressure exceeds the opening force. Mainly used in fluid situations.
Safety valves are required to have better reliability than relief valves.
Safety valves and relief valves are similar in structure and performance, both of which automatically discharge the internal media when the opening pressure is exceeded to ensure the safety of the production unit. Because of this intrinsic similarity, people tend to confuse the two when they are used, and some production devices also have rules that specify which one to choose.
