FPA, FPB gas flame arrester and ball Industrial Valves difference is bigger, we can distinguish from the function to go up and ball valve and FPA, different role of FPB gas pipeline flame arrester, from ball Industrial Valves and FPA, the structure of the FPB gas pipeline flame arrester. 【 Functional difference between 】 FPA, FPB gas pipeline flame arrester is suitable for installation in the transport of combustible gases such as regenerative furnace fuel gas, natural gas, liquefied petroleum gas, coal mine gas emission of pipe network, also applies to domestic gas pipeline, prevent under normal circumstances the flame in reverse transmission pipeline, to avoid a catastrophic accidents. Fire safety speed 1425 m/s; Limit fire speed 1605 m/s. This product is the use of metal corrugated board between slit gap for the spread of the pipeline subsonic or supersonic flame quenching effect of the original design and manufacturing. Ball valve and FPA, FPB gas flame arrester 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 】 FPA, FPB gas pipeline ball valve flame arrester 【 Summary 】 FPA, FPB gas flame arrester and ball valve and using 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, whether at design time, or in the purchase, must be in strict accordance with the relevant technical requirements.
