Application of vacuum negative pressure safety valve

The vacuum negative pressure safety valve is used in the negative pressure system. When the negative pressure in the negative pressure container exceeds the allowable value, the valve automatically opens to suck in air; When the negative pressure in the container decreases to the specified value, the valve will automatically close, so as to protect the safe operation of the equipment container and system.

Vacuum negative pressure safety valve is used for normal non negative pressure systems, and various corrosive media containers, such as absorption tower, storage tank, distillation tower, tank, etc. when steam is introduced for cleaning, if the blow off valve is not opened, steam condenses and generates negative pressure, patrol equipment to ensure equipment safety.
