ZFQ - 1 n breathing Industrial Valves and ball Industrial Valves sealing difference is large, we can distinguish ball valve and ZFQ - from function 1 n the different function of respiration valve, from ball valve and ZFQ - 1 n breathing valve sealing structures. 【 Functional difference between 】 ZFQ - 1 nitrogen sealed breathing valve set flame arrestor and breather valve, its novel structure for domestic initiative. Is a new type of safety equipment in petrochemical tank necessary, its biggest advantage is breathing fire performance is good, light weight, easy to use. The product is suitable for storage in something less than 28 ℃ a oil and flash point is lower than 60 ℃ b product, such as gasoline, stupid, stupid, kerosene, light diesel oil, engine oil, crude oil and oil products and chemical products, all of the same character storage tank is used. A fire also single or single suction valve. Ball valve and ZFQ - 1 n breathing valve sealing 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 】 ZFQ - 1 n breather valve sealing ball valves 【 Summary 】 ZFQ - 1 n breathing Industrial Valves and ball valve sealing difference on and use 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.
