Embodiment
For the technical characterstic of this programme can be clearly demonstrated, below by embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As depicted in figs. 1 and 2, a kind of flange, comprise flange body 1.1, described flange body 1.1 is provided with central through bore 1.2, the periphery of described central through bore 1.2 is provided with connecting through hole 1.3, an end face of described flange body 1.1 is provided with circular groove 1.4, the width of rebate of described circular groove 1.4 is less than the slot bottom width of circular groove 1.4, elastic seal ring 2 is provided with in described circular groove 1.4, the cross section of described elastic seal ring 2 is circular, the degree of depth of described circular groove 1.4 is less than the diameter of elastic seal ring 2, the width of rebate of described circular groove 1.4 is less than the diameter of elastic seal ring 2.During use, elastic seal ring 2 is squeezed in circular groove 1.4, when two Flange joint, due to the fastening effect between flange, elastic seal ring 2 is made to be subject to the extruding of high strength, and after elastic seal ring 2 is squeezed, major part elastic seal ring 2 is pressed in circular groove 1.4, elastic seal ring 2 is got up by circular groove 1.4 seal protection, decrease the exposed aerial area of elastic seal ring 2, slow down the aging speed of elastic seal ring 2, described elastic seal ring 2 is built in circular groove 1.4, not easily drop, and the phenomenon of neglected loading elastic seal ring 2 can be avoided, reduce the duplication of labour.
