The air valve is a special valve used to prevent negative pressure in the tube caused by transient decompression waves. It is usually installed in the pipeline normal operation of the dynamic water pressure is low, the transient flow process, it is possible to produce liquid column separation of the high point. When the pressure in the pipeline is lower than atmospheric pressure, the air is inhaled, and when the pressure in the pipeline is higher than atmospheric pressure, the air is discharged. During the exhaust process, when the liquid in the pipe fills the pipe, the valve can automatically close and does not allow the liquid to leak into the atmosphere.
