QPCARX composite exhaust valve

Structural features and uses

 

The QPCARX composite exhaust valve body is in the shape of a barrel, and the valve internals include stainless steel floats, levers and discs. The valve is installed at the pump outlet or in the water distribution pipeline to remove the air accumulated in the pipe to improve the efficiency of the pipeline and the water pump. When a negative pressure is generated in the pipe, the valve quickly inhales the outside air to prevent the pipeline. Damaged due to negative pressure. When the water injection starts in the tube, the valve flap is in the position of opening the account, and a large amount of exhaust is performed when the air is exhausted. The valve is filled with water, the float rises and the flap closes, stopping the exhaust. When the water in the pipe is normally transported, if a small amount of air collects 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 is stopped. The water in the pipe is empty or a negative pressure is generated inside the pipe. At this time, the plug quickly opens the account and draws in air. Make sure the pipeline is safe.
