The function of the safety valve of Shanghai Mingjing Anti corrosion Valve Manufacturing Co., Ltd.:

Sanitary safety valves play a safety protection role in the system. When the system pressure exceeds the specified value, the sanitary safety valve opens to release a portion of the gas/fluid in the system into the atmosphere/pipeline, ensuring that the system pressure does not exceed the allowable value and preventing accidents due to excessive pressure.

There are two main types of safety valve structures: spring type and lever type. Spring type refers to the sealing between the valve disc and the valve seat relying on the force of the spring. The lever type relies on the force of the lever and heavy hammer. With the demand for large capacity, there is another type of pulse type safety valve, also known as pilot operated safety valve, which consists of a main safety valve and an auxiliary valve. When the pressure of the medium in the pipeline exceeds the specified pressure value, the auxiliary valve opens first, and the medium enters the main safety valve along the pipeline, and the main safety valve is opened to reduce the increased medium pressure.

The discharge capacity of a safety valve is determined by the diameter of the valve seat and the opening height of the valve disc, and can also be divided into two types: the micro opening opening height is (1/15) to (1/20) of the inner diameter of the valve seat, and the full opening height is (1/3) to (1/4).

In addition, depending on the usage requirements, there are enclosed and non enclosed types. Closed type means that the discharged medium does not leak out and is completely discharged along the designated outlet. It is generally used for toxic and corrosive media. Non enclosed type is generally used for non-toxic or non corrosive media.
