Scar sewage composite air exhaust valve


Description: Sewage raft valve body for the drum-shaped, valve parts, including stainless steel float, stem and the valve, the valve is installed in the pump outlet or water distribution pipelines used to exclude the product in a tube of air in order to improve efficiency in the use of pipelines and pumps, when the negative pressure tube, this valve rapidly inhalation of ambient air in order to prevent pipeline damage due to negative pressure. In the open position when the water injection tube, the valve braided a lot of exhaust charge dripping when the air is drained, the valve float to rise and drive the valve closed. To stop the exhaust when the normal transportation of water in the tube such as gathered a small amount of air in the valve and to a considerable extent, the water level drop within the valve, then the air discharged from the holes. When the pump stops, the negative pressure, flow empty tube or a case of tube plugs quickly open, inhaled air and ensure pipeline safety.
