Detailed Description
The composite splicing pipeline comprises a first pipeline body and a second pipeline body 1 which is assembled with the first pipeline body in a butt joint mode, wherein a movable joint 4 is arranged at one end, opposite to the second pipeline body 1, of the first pipeline body, the first pipeline body comprises an inner pipe 8 and an outer pipe 6, the outer pipe 6 is sleeved outside the inner pipe 8, one end of the inner pipe 8 extends out of the outer pipe 6, an elastic air bag 3 is sleeved on the outer side face of the extending end of the inner pipe 8, one side end face of the elastic air bag 3 is in contact with one side end face of the outer pipe 6, the other side of the elastic air bag 3 is in contact with the end face of the movable joint 4, a filling air bag 7 is arranged inside the outer pipe 6, more than one through hole is formed in one side face, opposite to the inner pipe 8, of the outer pipe 6 is provided with the through holes, an inflation convex part 72 is arranged at the position, opposite to the through holes, of the filling air bag 7, the inflation, the inflatable convex part 72 of the expansion bulge is buckled in the positioning hole and used for limiting the displacement of the outer pipe 6 and the inner pipe 8 in the length direction, and the first pipeline body and the second pipeline body 1 are directly assembled and sealed through an elastic air bag or assembled and sealed through a movable joint.
As shown in fig. 3, the movable joint 4 includes a first connecting portion 41 and a second connecting portion 42, the outer wall surfaces of the first connecting portion 41 and the second connecting portion 42 are all provided with external threads, the inner tube 8 is provided with a first discharge passage 9, the movable joint 4 is provided with a butt joint passage 5 with openings at two ends, the second pipeline body 1 is provided with a second discharge passage 2 inside, the butt joint passage 5 connects the first discharge passage 9 and the second discharge passage 1 in a butt joint manner, the open ends of the first discharge passage 9 and the second discharge passage 2 are both provided with internal threads, and the outer diameter of the first connecting portion 41 is equal to the outer diameter of the first pipeline body.
Example 1
As shown in fig. 1 and 4, when the outer diameter of the first connection portion 41 is equal to the inner diameter of the second discharge channel 2, the first connection portion 41 is engaged and sealed with the thread section in the second discharge channel 2, a side end face of the elastic airbag 3 is extruded through the second pipeline body 1, so that the elastic airbag 3 generates expansion deformation, and through transitional rotation, the second discharge channel continuously extrudes the elastic airbag 3, so that the elastic airbag 3 generates elastic deformation, the sealing at the interface is realized by using elastic bounce, and meanwhile, the looseness of the thread engagement part is prevented. Furthermore, receive the shearing after destroying in first pipeline, because the contact of 3 side end faces of elasticity gasbag and 6 terminal surfaces of outer tube, like this when filling gasbag 7 when being destroyed, inside gas is gone out from damaged mouthful department, the convex part of aerifing no longer expands the protrusion this moment, and then inside the withdrawal outer tube, separate with the locating hole, this moment under the elasticity promotion of elasticity gasbag, make the outer tube along the length direction displacement of inner tube, make damaged mouthful dislocation, realize self-sealing with this, use safelyr, and when filling the gasbag and not having the damage and when normally using, by aerifing convex part and locating hole location, make between the interior outer tube at length direction location, the elasticity gasbag just can not promote the outer tube like this.
Example 2
As shown in fig. 2, when the inner diameter of the second discharge passage 2 of the second pipeline body 1 is larger than the outer diameter of the first connection portion 41, the elastic airbag 3 between the movable joint 4 and the outer tube 6 is compressed by rotating the movable joint 4, the outer diameter of the compressed elastic airbag 3 is increased, the outer diameter of the elastic airbag 3 is adjusted to be larger than the inner diameter of the second discharge passage 2, and then the entire first pipeline body is installed in the second discharge passage 2, and the entire second discharge passage 2 is sealed by the elastic airbag 3. In order to increase the sealing performance after assembly, more than one O-shaped sealing ring 31 is wrapped on the outer wall surface of the elastic air bag and is in sealing contact with the inner wall surface of the second discharge channel 2 through the O-shaped sealing ring 31.
It will be noted that when the resilient bladder 3 is installed in the second discharge passage 2, it avoids the internal thread section and seals against the smooth face end of the second discharge passage, otherwise leakage may occur. In this embodiment, the first pipe body also has the self-sealing capability in embodiment 1, but it makes the elastic airbag recover deformation, so that the first pipe body is no longer assembled with the second pipe body in a sealing manner, and there is leakage at the interface, so in order to prevent this situation, it is necessary to fill a layer of glass glue layer 10 between the outer wall surface of the first pipe body and the inner wall surface of the second discharge channel, and sealing is achieved through glass glue, and the glass glue only contacts the inner wall of the second discharge channel and the outer wall surface of the outer pipe, at this time, after the air-free inside of the filled airbag, the elastic airbag can only push out the movable joint towards the depth of the second discharge channel, because the movable joint is engaged with the thread of the inner pipe, after the elastic airbag recovers, its outer diameter becomes small and its width becomes large, at this time, the movable joint is used to drive the inner pipe to displace relative to the outer pipe, which is a little different from embodiment 1, meanwhile, the sealing performance can be further improved by utilizing the glass cement in the embodiment.
The invention has the beneficial effects that: when the apertures of the two pipelines are not matched, the assembly can be completed by adjusting the elastic air bag, so that the problem that the two pipelines cannot be mutually butted and assembled due to different apertures is solved;
in addition, the elastic air bag can be extruded by adjusting the movable joint, so that the length of the first pipeline body can be adjusted, and fine adjustment treatment on certain lengths can be met;
when the two pipelines can be mutually matched and butted, the second pipeline body can be used for extruding the elastic air bag, the elastic deformation force of the elastic air bag is used for sealing the butted joint, the sealing performance after thread assembly is improved, and the looseness of the pipelines is further prevented; simultaneously first pipeline body can utilize elastic deformation's elasticity gasbag to come the outer tube along inner tube length direction displacement after taking place the damage, and then utilizes the dislocation of interior outer tube to realize self-sealing, need not the manual work and maintains, prevents the leakage of inside emission.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
