The valve body of the CARX composite exhaust valve is barrel-shaped, and the internal parts of the valve include stainless steel float, lever and valve clack. This valve is installed at the outlet of the pump or in the water distribution pipeline to remove the air accumulated in the pipe to improve the efficiency of the pipeline and the pump. Once negative pressure is generated in the pipe, the valve quickly sucks in outside air to prevent the pipeline Damaged by negative pressure. When the pipe starts to inject water, the valve flap is in the open position, and a large amount of exhaust is performed. When the air is exhausted, the valve is filled with water, the float rises and drives the valve flap to close, stopping the exhaust. When the water in the pipe is normally transported, If a small amount of air accumulates 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. Medium temperature: 0-80℃.
