The compound exhaust interbody is barrel-shaped, and the inner parts include stainless steel float ball, lever and disc.Installed in the pump outlet or water distribution pipeline, used to remove the accumulated air in the pipeline, to improve theefficiency of the line and the pump, when there is a negative pressure in the pipe, the rapid inhalation of external air to prevent pipeline damage due to negative pressure.
When the pipe begins to fill with water, the disc is in the open position and a lot of air is drained. When the air is exhausted, the valve is filled with water. Float up and drive indirectly closed, stop the exhaust, when the pipe water normal transmission, if there is a small amount of air in the valve to a considerable degree, the water level in the valve dropped, when the air from the hole discharge. When the pump stops, the water flow in the pipe is empty or meets the pipe, the negative pressure is generated in the pipe, at which point the plug head is quickly opened and the air is inhaled to ensure the safety of the pipeline.
