Product description:

This product is used for the pipeline where the highest point or elbow or breath, and to exclude gas pipe to clear the pipeline, to work properly. If you do not install the valve, the pipeline at any time air resistance, so that the water capacity of the pipeline does not appear to design requirements, and secondly; pipeline outage occurs during operation, stop the pump piping timely negative pressure can cause pipe vibration or broken exhaust, intake valves quickly put air into the pipe to prevent pipe vibration or breakage of principle: when the water. when entering the pipeline, stopping plugs in the lower spacer, extensive venting, when the air is drained, the water enters the valve ball float, drive plugs into closed to stop the exhaust. naturally arises in the normal operation of pipeline a small amount of gas, the gas will be gathered into the upper tube, to a considerable extent, the water level dropped valve, float sailing decrease gas discharged from the hole, where there is a power failure, stop the pump at any time there will be a negative pressure within the pipeline flow is empty, the float sailing decline, driven by large open pores lot intake hole to ensure pipeline safety .
