Introduce
The safety valve is a special valve in that the opening and closing parts are normally closed under the action of external force. When the medium pressure in the equipment or pipeline increases beyond the specified value, the medium pressure in the pipeline or equipment is prevented from exceeding the specified value by discharging the medium outside the system. Safety valve belongs to the automatic valve category, which is mainly used in boiler, pressure vessel, and pipeline. The control pressure does not exceed the specified value, which plays an important role in protecting personal safety and equipment operation. Note the safety valve can only be used after the pressure test.
Explain
The safety valve plays a role in safety protection in the system. When the system pressure exceeds the specified value, the safety valve will be opened to discharge part of the gas/fluid in the system out of the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, to ensure that the system will not have an accident due to the high pressure.
