Product overview
SCAR composite exhaust valve, the valve body is barrel shaped, and the valve internals include stainless steel floating ball, valve stem and valve disc. The valve is installed at the pump outlet or in the water distribution pipeline to remove the air accumulated in the pipe. Once negative pressure is generated in the pipe, the valve quickly sucks in the external air to prevent the pipeline from being damaged due to negative pressure. When water is injected into the pipe, the valve disc is in the open position and a large amount of air is exhausted. When the water is discharged, the valve is filled with water, and the floating ball rises to drive the valve disc to close and stop exhaust. When the water in the pipe is normally transported, a small amount of air is accumulated. When the water level drops, the air is discharged from the small hole. When the water pump stops, the water flow in the pipe is empty or negative pressure is generated in the pipe. At this time, the plug is quickly opened to inhale air to ensure the safety of the pipeline.
