Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Embodiment 1
In the present embodiment, the concrete restrictive condition of institute's connecting tube by: connected two pipelines, the end of one of them pipeline is removable.
To shown in Figure 6, the utility model pipeline is with comprising connecting sleeve 1, seal ring 2, lining 3, retaining ring 4 in the fast connected components like Fig. 1.
During assembling, move the end of a pipeline, enlarge the distance between two pipes, 5,6 ends; In pipeline 6 ends; Suit retaining ring 4, lining 3, seal ring 2, connecting sleeve 1 successively, then at pipeline 5 ends suit retaining ring 4 successively, lining 3, seal ring 2, two pipelines, 5,6 ends of aliging.
At first; On pipeline 5, lining 3 is located; Lining 3 outboard end screw threads 305 are docked with retaining ring 4 internal threads 401 tighten; The conical surface 402 is through the conical surface 303 of roof pressure lining 3 outboard end ends on the retaining ring 4, makes lining 3 outboard ends, 302 radial contraction and is locked with pipeline 5 in the hole, lining, realizes the location of lining 3 on pipeline 5 and fixing thus.The seal ring 2 of on connecting sleeve 1 an end toper section 102 positions, packing in the face of fixing lining 3; Moving connecting sleeve 1 then docks with fixing lining 3; Internal thread 103 docks with the outside thread 301 of lining 3 inboard ends and tightens on the connecting sleeve 1; Lining 3 inboard end end face 304 inside pushing tow seal rings 2 compress the taper fit face 202 on seal ring 2 internal surfaces 201 and the outer surface respectively, thereby pipeline 5 and connecting sleeve 1 are tightly connected with the outer surface of pipeline 5 and the conical section 102 on the connecting sleeve 1.
Then; In pipeline 6 one sides; Suit seal ring 2, lining 3 successively on the position of connecting sleeve 1 conical section 102, screw thread 103, and tighten lining 3, lining 3 inboard end 304 inside pushing tow seal rings 2; Make seal ring 2 internal surfaces 201 and outer surface 202 respectively with pipeline 6 outer surfaces and connecting sleeve 1 on conical section 102 compress, realize being tightly connected of connecting sleeve 1 and pipeline 6.
At last; The retaining ring 4 of pipeline 6 one sides is tightened with the outboard end outside thread 305 of lining 3; The conical surface 303 on the conical surface 402 extruding linings 3 on the retaining ring 4 makes that lining 3 is outer then to be held 302 radial contraction and be locked with pipeline 6 in the hole, lining, and accomplishes pipeline 5 thus and be connected with the quick of pipeline 6.
In order to make seal ring 2 and to be arranged in the pipeline external surface in hole in it and 102 reliable airtight the joining of conical section in 1 li hole of connecting sleeve; As shown in Figure 7; Also be spaced several bulge loops 204 in the seal ring 2 on the sidewall of hole vertically, be spaced several bulge loops 203 on the fitting surface 202 on seal ring 2 outer surfaces equally vertically.
Embodiment 2
The concrete restrictive condition of this programme institute connecting tube is: connect two pipelines, the ends of tubes fixed distance can not move.
Like Fig. 8, shown in Figure 9, connecting sleeve by about two sections 8A, 8B butt joint form, left side section 8A and right section 8B are through screw thread 805 butt joints on the screw thread 804 on the section 8A of a left side and the right section 8B.
During assembling; Inspection two pipes 5,6 tip spacings are from being not less than lining 3, connecting sleeve radial length; Therein on the pipeline 6; Successively suit retaining ring 4, lining 3, seal ring 2, left side section 8A, right section 8B dock left side section 8A after adding sealing material on the screw thread 805 of right section 8B then and tighten with a right side section 8B; Priority suit retaining ring 4, lining 3, seal ring 2 in pipeline 5 ends.
On pipeline 5, lining 3 is located; Lining 3 outboard end screw threads 305 dock with retaining ring 4 internal threads 401 to be tightened; The conical surface 402 on the retaining ring 4 is through the conical surface 303 on the compressing lining 3, makes lining 3 outboard ends, 302 radial contraction and is locked with pipeline 5 in the hole, lining.End face 304 in the face of fixing lining 3; The seal ring 2 of on an end toper section 802 positions of combined type connecting sleeve, packing into; Then the internal thread on the connecting sleeve 803 is docked with the outside thread 301 of lining 3 inboard ends and tighten; Make seal ring 2 internal surfaces 201, outer surface 202 under the pushing tow of lining 3 inboard ends 304 respectively with pipeline 5 outer surfaces, connecting sleeve on conical section 802 compress, thereby realize being tightly connected of connecting sleeve and pipeline 5.
Subsequently, the seal ring 2 of on opposite side conical section 802 positions of connecting sleeve, packing into, and press step mounting bush 3, the retaining ring 4 of the foregoing description 1, accomplish remaining connection procedure.
Embodiment 3
Shown in figure 10, different is with the foregoing description, also is provided with on connecting sleeve 7 sidewalls among this embodiment to supply the flow-guiding mouth that is connected with external pipe.
