When water is injected into the pipe, the valve disc is in the open position for a large amount of exhaust. When the air is exhausted, the valve is full of water, the floating ball rises and drives the valve to close, and the exhaust stops. When the water in the pipe is normally transported, if a small amount of air accumulates in the valve to a considerable extent, the water level in the valve drops, and the air is discharged from the small hole at this time. When the water pump stops, the water flow in the pipe is empty or negative pressure is generated in the pipe. At this time, the plug is quickly opened to inhale air to ensure the safety of the pipeline.
