During the operation of the pipeline, the gas in the water will escape and accumulate in the elevated part of the pipeline, and even form a gas block. When the water flow in the pipe fluctuates, the air bag formed in the raised part will be continuously compressed and expanded, and the gas will be compressed. The pressure generated afterwards is dozens or even hundreds of times stronger than the pressure generated after water is compressed. At this time, the pipeline is prone to rupture.
Therefore, the Brass Air Vent Valve is designed during the pipeline design. Generally, in plain areas with small fluctuations, the pipeline should be artificially designed to undulate during trenching, which is cyclically rising or falling, with a slope of not less than 1/500, and set at the highest point per kilometer. 1-2 Brass Air Vent Valves. In hills or mountains with large undulations, a Brass Air Vent Valve should be set at the highest point of each undulation. The specification of the Brass Air Vent Valve is 1/8-1 of the original pipe diameter. /10.
