Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
In a specific embodiment, with reference to Fig. 1~3, a kind of dismountable bump joint, including flange body 1 and
Back-up ring 2；Include pipe hole 11 and screw 12 in the flange body 1；The lower end of the flange body 1 is provided with the step trough 13 of annular
And the groove 14 of annular；The groove 14 is used to accommodate the back-up ring 2.
The pipe hole 11 is used to be socketed pipeline, can be docked with other kinds of flange after socket pipeline, now leads to
Cross and bolt is fastened through screw 12.Step trough 13 may be contained within the inwall of the lower end of the flange body 11 with groove 14
On.
In a specific embodiment, with reference to Fig. 4, Fig. 5, a kind of pipeline docking facilities, including bump joint and pipe end
3；The pipe end 3 includes straight-through pipeline section 31 and bulge loop 32, the bulge loop 32 and the joining distal ends of straight-through pipeline section 31；The bulge loop
32 external diameters are more than the straight-through pipeline section 31, and the bulge loop 32 is coaxial with the straight-through pipeline section 31；The bulge loop 32 and the ladder
