The sewage composite exhaust valve is a barrel The valve body is mainly composed of stainless steel float and plug. The sewage composite exhaust valve is installed at the pump outlet or in the water distribution pipeline to remove a large amount of accumulated air in the pipeline. It is used at the highest point on the pipeline or in places where air is blocked to remove the gas in the pipe to clear the pipeline
to achieve normal operation. If the exhaust valve is not installed, the liquid flowing in the pipe

The generation of dynamic heat causes gas, forming a short circuit, causing the water outlet capacity of the pipeline to fail to meet the requirements. Secondly, if there is a power outage or pump stop during the operation of the pipeline, negative pressure will appear in the pipeline, which will cause the pipeline to vibrate or rupture, and the exhaust (suction) valve will quickly Draw air into the pipe to prevent the pipe from vibrating or bursting.
When the pipe starts to be filled with water, the plug stays in the open position and a large amount of exhaust is carried out. When the air is exhausted, the water float ball in the valve is floated and the plug is driven to the closed position to stop the large amount of exhaust. When the water in the pipe is transported normally, if a small amount of air accumulates in the exhaust valve to a considerable extent, the water level in the valve will drop, and the float will drop accordingly. At this time, the air will be discharged through the small hole. When the water pump stops and the water in the pipe is empty, or when negative pressure occurs in the pipe, the plug opens and air is sucked in to ensure the safety of the pipeline.
