CARXComposite exhaust valveUsed at the highest point or where there is a closed valve on the pipeline, to remove the gas inside the pipeline to clear it and achieve normal operation. If an exhaust valve is not installed, the liquid flowing inside the pipeline will generate kinetic heat and cause gas to form a short circuit, resulting in insufficient water discharge capacity of the pipeline. Secondly, when there is a power outage or pump stop during pipeline operation, the pipeline will experience negative pressure, which can cause pipeline vibration or rupture. The exhaust (suction) valve will quickly suck air into the pipeline to prevent pipeline vibration or rupture.

When water starts to be injected into the pipe, the plug stays in the open position for a large amount of exhaust. When the air is exhausted, the accumulated water in the valve floats up, and the plug is driven to the closed position to stop a large amount of exhaust; When the water in the pipe is transported normally, if a small amount of air accumulates in the valve to a considerable extent, the water level in the valve drops, and the float ball also drops. At this time, the air is discharged through the small hole. When the pump stops and the water flow in the pipe is empty, or when negative pressure is generated in the pipe, the plug opens to suck in air to ensure the safety of the pipeline.

Composite exhaust valveStructure and Application

The CARX composite exhaust valve has a cylindrical valve body, mainly consisting of stainless steel floating balls and plugs inside.

The CARX composite exhaust valve is installed at the outlet of the pump or in the water supply and distribution pipeline to remove a large amount of accumulated air in the pipeline, in order to improve the efficiency of the water pipe and pump. Once negative pressure occurs inside the pipeline, this valve can quickly suck in air to prevent damage to the pipeline caused by negative pressure.
