The function of air valve is as follow.

Air valve is a breathing apparatus for pipelines and a safeguard for pipeline safety. It is also known as a ventilation valve or exhaust valve, but it has a suction function, so it is more accurate to call it an air valve. The air valve is a small caliber air valve with a single exhaust function, also known as a micro exhaust valve; Large caliber air valves with both exhaust and intake functions, including high-speed intake and exhaust air valves, composite air valves, etc; Air valve with single intake function, also known as suction valve or vacuum breaking valve. When filling the pipeline with water, the faster the gas inside the pipeline is discharged, the faster the water filling speed will also be; If the water pressure for filling is too high, the flow rate is too fast, and the air valve quickly seals the ball, it is easy to produce water hammer; When the pipeline is in the drainage process, if air is not timely sucked into the pipeline through the air valve or suction valve (vacuum breaking valve), on the one hand, the drainage is not smooth, and on the other hand, negative pressure (forming a vacuum phenomenon) is prone to occur. For commonly used pipes, this negative pressure will not cause harm. If the stiffness of some pipes is insufficient, such as large thin-walled steel pipes, it is easy to cause geometric deformation of the pipes, causing water leakage faults. At the same time, sewage and sludge outside the pipes will be sucked into the pipes, endangering water supply safety.
