QB2 double exhaust valve and ball valve flange difference is large, we can distinguish from the function to go up and ball valve and flange duplex QB2 different role of exhaust valve, also from ball valve and QB2 flange double construction up to distinguish between the exhaust Industrial Valves. 【 Functional difference between 】 QB2 flange duplex exhaust valve is suitable for the working medium for water piping, to improve the efficiency of water equipment and protect the pipes from deformation, is an essential equipment for pipeline. For most of the store on the pipeline and the pump outlet or have a breath, eliminate gas in pipe line to dredge pipeline, to work properly. If you don't install exhaust valve, pipe a vapor lock at any time, make the pipe water capacity can not meet the design requirements; Second, pipe stop pump during operation, blackouts will produce negative pressure pipeline vibration or break, quick exhaust valve can quickly put the air suction tube, prevent the pipeline vibration or broken. Ball valve and flange duplex QB2 exhaust valve difference is bigger, ball valve, 球阀) Opening and closing is a sphere, driven by the valve stem, and for ball valve axis rotate 90 & deg; Open or closed. Can also be used on regulation and control of fluid, mainly used for cutting in line, distribution, and change the flow direction of medium, good sealing, convenient operation, opening and closing fast, simple structure, small volume, small resistance, light weight, etc. 【 Physical difference between 】 QB2 flange double mouth exhaust valve ball valve' Summary 】 QB2 flange double mouth exhaust valve and ball valve and the difference function, are quite different in application, in the selection of a certain need to pay special attention to diameter, pressure, material and use of media, no matter when the design, or in the purchase, must be in strict accordance with the relevant technical requirements.
