The valve shall be used in water treatment system and installed at the highest point of pipeline or vessel. When the pump is stopped or the water is drained quickly, a vacuum will be generated in the pipeline. At this time, the atmospheric pressure outside the valve is higher than the pressure inside the container, and the air will enter the pipeline to prevent the pipeline from being compressed. When the pump is turned on, the air inside the pipe will be discharged through the micro vent valve, so as to prevent the generation of water hammer. Protect the safety of pipes and pumps.
