SKCARX compound exhaust valve

The SKCARX composite exhaust valve body is round and oval. The internal parts of the valve include stainless steel float ball, lever and disc. The valve is installed at the outlet of the pump or in the water distribution pipeline to exclude the air collected in the pipe to improve the efficiency of the pipeline and the water pump. Once the negative pressure is generated in the pipe, the valve quickly sucks in the outside air to prevent The pipeline is damaged by negative pressure. When the tube begins to fill water, the valve flap in the open position, a large amount of exhaust, when the air is exhausted, the valve is filled with water, floating ball rises and drives the valve flap to close, stop exhaust, when the water in the tube is normally transported, if there is a small amount of air gathered in the valve to a considerable extent, the water level in the valve drops, at this time the air is discharged by a trace exhaust valve or small hole. When the water pump stops, the water in the pipe is empty or negative pressure is generated in the pipe, and the air is quickly sucked in to ensure the safety of the pipeline.
