 I. Overview 

 P41X series of quick exhaust valve for the drum-shaped valve, the valve parts, including stainless steel float, stem and disc. The valve installed at the outlet of the pump or water distribution pipeline, set to exclude the air volume in the pipeline to improve the efficient use of pipelines and pumps, when the pipeline once the negative pressure, the valve quickly inhaled the outside air, to prevent pipeline damage due to negative pressure. When the pipeline began to water, the valve flap in the open position, a lot of exhaust, the air drained, the valve is filled with water, the float valve shut up and drive, stop the exhaust, when the normal delivery of water pipe When, if gathered in a small amount of air to a considerable extent within the valve, the valve the water level dropped, this time the air discharged from the hole. When the pump stops, the air flow tube or a case of negative pressure tube, then quickly open the plug head, inhaled the air, to ensure pipeline safety.
