Product Description Product DescriptionProduction introductionThis product is used at the highest point of pipeline,the place where air is shout off, or the outlets of pumps in order to eliminate air and dredge pipeline, if the vent valve is not set, the air in the pipeline will be possibly shutoff at any time,and the water content willnot meet the design requirement, if the electricity is suddenly cut off when pipeline is at work, the negative pressure in the pipeline willcause vibration or cracking.In this case.the vent valve can quickly inhale air into the pipeline and prevent the vibration and cracking of it. Operating PrincipleThere are two holes in the compound vent valve,one big, one small.the diameter nearly equals DN, the frist time water is passed in the pipeine a large amount of air will be released through the big hole,immediately the air is completely removed,the big hole stops working, when the pipeline is at work air cells will be generated, and air cells will grow bigger while move to the upper part of the pipeline, which willhave a negative influence on the flow in the pipeline,at this moment these air cells can be removed through the smallhole. Therefore no air can exist in the pipeline, in order to inhale a lot of air, a foating ball will fall and open the small hole which will drive the opening of the big hole. Warning:the working pressure of vent valve cannot be over 0.02MP,if not water will be leaked, andThis valve should be equipped with another valve for its maintenance.Technical Parameters 1.
