The compound exhaust valve is a barrel-shaped valve body, which mainly contains a set of stainless steel balls (STAINLESS STEEL BALL), rods (FLOAT ARM) and plugs (POPPET). The valve is installed at the pump outlet or in the water distribution pipeline to remove a large amount of air collected in the pipe, or to discharge a small amount of air collected at a higher point of the pipeline to the atmosphere, so as to improve the efficiency of the pipeline and the pump, and When a negative pressure is generated in the pipe, the valve quickly inhales the outside air to protect the pipeline from damage caused by the negative pressure.
