Product Description
The valve body of the compound exhaust valve is barrel-shaped, and the internal parts include stainless steel float, lever and valve clack. Installed at the outlet of the pump or in the water distribution pipeline to remove the air accumulated in the pipe and improve the efficiency of the pipeline and the pump. When negative pressure is generated in the pipe, the outside air is quickly sucked in to prevent the pipeline from being damaged due to negative pressure. When the pipe starts to fill with water, the valve flap is in the open position and a large amount of air is exhausted. When the air is exhausted, the valve is filled with water. The floating ball rises and drives the valve to close to stop the exhaust. When the water in the pipe is normally transported, if a small amount of air gathers in the valve to a considerable extent, the water level in the valve drops, and the air is discharged from the small hole. When the water pump stops, the water in the pipe is empty or negative pressure is generated in the pipe. At this time, the plug opens quickly to inhale air to ensure the safety of the pipeline.
