GJQ(X)-DF-II Single Sphere Flexible Rubber Expansion Joint
GJQ(X)-DF-II Single Sphere Flexible Rubber Expansion Joint is a kind of full face rubber joint, it’s made of rubber joint sphere and flange or flat union. Rubber joint sphere is a recombination of inner & outer glue line and enhancement layer.
GJQ (X) -DF-II type single sphere flexible rubber joint is a kind of single sphere end face full sealing flexible rubber joint. " DF " in the " GJQ (X) -DF " shows a single sphere, and "II" refers to the end of the whole seal. A small edge along the card slot type is on the opposite（side）of the end face of the full sealed rubber joint. The edge of the rubber joint is relatively wide, which has been extended to the outer edge of the flange.Above the outer edge of the rubber joint ,there are bolt holes corresponding to flange.
GJQ (x) -DF-II type single sphere flexible rubber joint has same inner layer and outer layer rubber material with GJQ (x) -DF-I type flexible rubber joint,which can choose any kind of rubber material ,such as IIR, CR, EPDM, NR, NBR and so on. The external and internal layers of rubber material can be different. But skeleton layer of rubber joint are produced by polyester fabric and enhancement layer has a steel wire ring. Flange material is also diverse, common material is like Q235 SS304 and SS316. Flange Standard is also varied, different countries have different standards and commen standard is like GB standard, JIS standard ,ANSI Standard, DIN standard.GB flange standard can use GB/T 9119-2010 as a reference.
