Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment：
It can be seen from Fig. 1 to Fig. 4, the utility model includes the flange 1 at two ends, it is characterised in that the phase of the flange 1 at two ends
Running-on 2 is provided with to position, the outside of running-on 2, which is provided with opening 3, flange 1, is socketed with compensation pipe 4, and the two ends of compensation pipe 4 are provided with closing in
6, hand button outside is provided with straight tube 5, and straight tube 5 is socketed in running-on 2, and close up 6 and the cooperation of opening 3, closing in 6 are identical with open 3 angle,
It can be good at being coordinated during mating connection, between straight tube 5 and running-on 2, close up is set with sealing ring 7 between 6 and opening 3,
Sealing ring 7 can prevent the leakage of air and fluid, and compensation pipe 4 and the flange 1 of one end are fitted close, compensation pipe 4 and the other end
