I. Overview of sewage composite exhaust valve:
为圆桶式阀体,其内部主要有不锈钢浮球及塞头。 The sewage composite exhaust valve is a barrel-type valve body, which mainly contains stainless steel floats and plugs. 装设于泵浦出水口处或送配水管线中,用以大量排出管道中的集结之空气,以增进水管及抽水机使用效率,管内一旦出现负压时,此阀能迅速吸入空气, The composite exhaust valve is installed at the pump water outlet or in the water distribution pipeline to discharge a large amount of accumulated air in the pipeline to improve the efficiency of the water pipe and the pump. Once a negative pressure occurs in the pipe, the valve can quickly suck in air,
To ensure that the pipeline will not be damaged due to negative pressure, the pressure level is 1.0MPa.


Second, the role of sewage composite exhaust valve:

When the tube is filled with water, the plug stays in the open position for a large amount of exhaust. When the air is exhausted, the water accumulated in the valve body is floated, and the plug is driven to the closed position to stop a large amount of exhaust. During normal delivery,
If a small amount of air accumulates in the valve to a considerable extent, the water level in the valve drops, and the float drops with it. At this time, the air is discharged through the small hole. When the decanter stops, the water in the pipe is empty, or when negative pressure is generated in the pipe, the plug is opened at this time.
Inhale air to ensure line safety.
