1. When the pipeline starts to fill with water, the exhaust valve is required to discharge a large amount of air in the pipeline to ensure that there is no air in the pipeline when the pipeline is filled with water. The exhaust valve is required to match the large amount of water filled and the amount of water filled, which can shorten the filling time.
2. In the pipeline operation stage, the exhaust valve is required to discharge the moisture released in the micro air (about 2% of the volume) in time under the high pressure of the micro exhaust valve, so as to prevent the accumulation of air pockets in the pipeline from hindering the water flow and improve the water supply efficiency.
3. In the pipeline emptying stage, the exhaust valve is required to add a large amount of air to prevent negative pressure in the pipeline. At this time, the suction volume of the exhaust valve is required to match the drainage volume of the pipeline. When a local accident occurs in the pipeline, due to the inclination of the short knife, the water flow of the drainage flow is very large, requiring the exhaust valve to quickly add a large amount of air to prevent the pipeline from rupturing due to negative pressure.
