2.Feature

CARX composite exhaust valve body for round barrel, including stainless steel ball valve body, valve stem and disc. This valve is installed in the pump outlet or send water distribution pipeline, set is used to eliminate the air in the tube, to improve the efficiency of the use of the pipeline and water pump, when once produced negative pressure tube, this rapid inhalation outside air valve, in order to prevent the pipeline damage due to negative pressure.

When tube began to water injection, the disc in the open position, a large number of exhaust, when the air line up, the full of water in the valve, floating ball up and drive the valve closed, stop the exhaust, when water tube is normal transportation, if there is a small amount of air within the valve to a degree, water levels fall in the valve, floating ball drops, the air is being exhausted from the holes. When the pump stops, the tube water empty or negative pressure in the tube, the plug head quickly open, inhalation of air, to ensure pipeline safety.
