QY347F stainless steel oxygen valve,

Shanghai crown ring Valve Manufacturing Co. production of stainless steel oxygen valve, QY347F stainless steel oxygen valve as in the metallurgical industry road transport oxygen tube opening and closing device, compared with many other common valve compared to particularly stringent requirements. Because oxygen is a flammable dangerous goods, it is necessary leak-proof, anti-static, fire flower, in order to avoid accidents. I. Product Overview: Oxygen Ball as the metallurgical industry in the road transport oxygen tube opening and closing device, than other common valve compared to many particularly stringent requirements. Because oxygen is a flammable dangerous goods, it is necessary leak-proof, anti-static, fire flower, in order to avoid accidents. Structurally, the design is: open and close the valve stem when lifting instead of just rotating, effectively reducing the wear of sealing, packing seal wear and abrasion; grounding screw flange mounted on the side, to avoid static sparks; stem It closed with plexiglass cover exposed parts for dust and oil. Technical Data Body material 1Cr18Ni9Ti Nominal PN (MPa) 2.5 Nominal diameter DN (mm) 15-400 Performance Description Features have good sealing performance, light and flexible, safe and reliable, long life and other advantages. Second, the implementation of standards: the design and manufacture of structural length flange size pressure - temperature test - test GB122237 GB12221 GB9113 JB79 GB9131 GB / T13927 JB / T9092 Third, the pressure test: Nominal 1.6 2.5 4.0 2.4 3.8 6.0 strength test water sealing test 1.8 2.8 4.4 0.4-0.7 stainless steel oxygen gas seal test ball valve http://www.ghval.com/productlist/qf-1.html http://www.ghval.com/product/qf/112.html Shanghai
