Safety valve precision investment casting
The safety valve is in a normal shutdown state under the influence of external forces. When the pressure of the medium in the device or pipeline increases exceeds the specified value, the pressure in the pipeline or the device is prevented from exceeding the specified value of the specified value by discharge the medium to the outside of the system.
Essence The safety valve is an automatic valve class, which is mainly used for boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important protective role in personal safety and equipment operation. The safety valve must be tested by pressure.
Safety valves play a safe protection role in the system. When the system pressure exceeds the specified value, the safety valve is opened, and some of the gas/fluids in the system are discharged into the atmosphere/pipeline, so that the pressure of the system does not exceed the allowable value to ensure that the system does not cause an accident due to excessive pressure. According to different media emissions, the safety valve can be divided into three types: fully closed, semi -closed and open.
