SCAR complex exhaust valve

Product description:

SCAR Composite Exhaust Valve The valve body is barrel-shaped, and the internal parts of the valve include stainless steel float, lever and disc. The 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. When negative pressure is generated in the pipe, the valve quickly sucks in the outside air to prevent the pipeline from leaking. Damaged by negative pressure. The composite exhaust valve is used at the highest point on the pipeline or where there is a closed air to remove the gas in the pipe to dredge the pipeline and achieve normal work. If the exhaust valve is not installed, the liquid flowing in the pipe will generate kinetic heat and cause gas to form a short circuit. The water outlet capacity of the pipeline cannot meet the requirements. Secondly, when the pipeline is running, there will be a power failure or a negative pressure in the pipeline when the pump is stopped, which will cause the pipeline to vibrate or rupture. The exhaust (suction) valve will quickly suck the air into the pipeline to prevent the pipeline from vibrating or rupture. Its working principle is: when the pipe starts to fill with water, the valve disc is in the open position, and a large amount of exhaust is carried out. When the air is exhausted, the valve is filled with water, and the floating ball rises and drives the valve disc to close, and stops exhausting. When water is delivered normally, if a small amount of air accumulates in the valve to a considerable extent, the water level in the valve will drop, and the air will be discharged from the small hole at this time. 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 suck in air to ensure the safety of the pipeline. Medium temperature: 0-80℃
