Safety valves provide safety protection in the system. When the system pressure exceeds the specified value, the safety valve is opened, and a part of the gas/fluid in the system is discharged into the atmosphere/pipe, so that the system pressure does not exceed the allowable value, thereby ensuring that the system does not cause an accident due to excessive pressure.
The safety valve is an important accessory for safety protection of pressure limiting and pressure relief on special equipment (boilers, pressure vessels, pressure pipes, etc.). Safety valves are generally installed directly on special equipment. His design, manufacture, installation, use, inspection, etc. must comply with the requirements of special equipment, because its operational reliability and performance are directly related to equipment and personnel. Safe and closely related to energy conservation and environmental protection.
