Description

Intelligent air valve

Technical Field

The utility model relates to an air valve technical field specifically is wisdom type air valve.

Background

The air valve is a special valve used to prevent transient decompression waves from generating negative pressure in the pipe. It is usually installed at the high point position where the dynamic water pressure is lower when the pipeline normally runs and the liquid column separation is possibly generated in the transient flow process. Air is drawn in when the pressure in the duct is below atmospheric pressure and is expelled when the pressure in the duct rises above atmospheric pressure. During the exhaust process, when the liquid in the pipe fills the pipeline, the valve can be automatically closed, and the liquid is not allowed to be discharged into the atmosphere.

However, the working state of the existing air valve during working is unknown all the time, and whether the existing air valve works normally cannot be judged; the float ball stroke is generally fixed in current air valve, and the float ball sets up inside the air valve usually moreover, and is inconvenient directly to be adjusted from the outside according to monitoring state.
