Compound exhaust valve
I. Introduction:
The CARX composite air release valve has a cylindrical valve body. The internal components of the valve include a stainless steel float, a lever, and a valve disc. This valve is installed at the pump outlet or in the water supply pipeline, used to exhaust air accumulated in the pipeline, so as to improve the service efficiency of the pipeline and the water pump. Once negative pressure is generated in the pipeline, this valve quickly inhales external air to prevent the pipeline from being damaged due to negative pressure. When water starts to be injected into the pipeline, the valve disc is in the open position to exhaust a large amount of air. When the air is exhausted, the valve is filled with water, the float rises and drives the valve disc to close, stopping the exhaust. When water is transported normally in the pipeline, if a small amount of air accumulates in the valve to a considerable extent, the water level in the valve drops, and at this time, the air is exhausted through the small hole. When the water pump stops, the water in the pipeline is emptied or negative pressure is generated in the pipeline. At this time, the plug opens quickly to inhale air, ensuring the safety of the pipeline.
