Pipe box center is identical, and flexible sealing ring is provided between second pipe box and outer protection tube, and the flexible sealing ring is arranged on installation cavity
It is interior, be provided with the first pipe box at the pipe joint, first pipeline simultaneously movable set in two outer protection tubes, the first pipe
Set two ends are located at respectively the installation intracavity of two the second pipe boxes, and the first pipe box top and flexible sealing ring are compressed.
Further, the flexible sealing ring offers draw-in groove, first pipe box in one end that compression is covered with first pipe
End is installed in the draw-in groove.
Further, second pipe box is wound with thermotape away between the side of pipe joint and outer protection tube.
Further, described two pipeline weldings are tightly connected.
Further, described two pipelines are respectively kept with ring-type reserved place in joint, and the ring-type reserved place outside sets
There is shrink wrap layer, the shrink wrap layer is located in the first pipe box.
Relative to prior art, the insulation collocation structure at a kind of pipe joint described in the invention has following excellent
Gesture：
(1) in the insulation collocation structure at a kind of pipe joint described in the invention, arranged using first pipe is covered
In two second pipe inner rooms, and first pipe set compresses flexible sealing ring, therefore when the change of pipeline stress deforms, it is described soft
Property sealing ring can be recompensed by the Flexible change of its own, it is ensured that the sealing between the first pipe box and outer protection tube, Jin Erbao
Will not be corrosion-damaged by the external world at pipe joint during card use.
(2) in the insulation collocation structure at a kind of pipe joint described in the invention, at two pipe joints outside
Side is provided with shrink wrap layer, and on the one hand the shrink wrap layer prevents heat to be lost in by pipe joint, on the one hand because the shrink wrap layer has necessarily
Ductility, therefore, equally there is compensating action to the deformation of pipeline.

Below with reference to the accompanying drawings and in conjunction with the embodiments describing the invention in detail.
As shown in figure 1, the insulation collocation structure at a kind of pipe joint, including 4, two and of the second pipe box 6 of the first pipe box
The pipeline 1 that two welded seals connect and connect, the outside of the pipeline 1 is enclosed with heat-insulation layer, and the heat-insulation layer outside is enclosed with
One outer protection tube 7, described two second pipe boxes 6 are fixedly set in respectively in two outer protection tubes 7, and second pipe box 6 closes on pipe
Road 1 joint is arranged, described two second pipe boxes 6 just to be provided with installation cavity, be provided with flexible sealing ring 5 in the installation intracavity,
The flexible sealing ring 5 will be sealed between the second pipe box 6 and outer protection tube 7, and first pipe box 4 is arranged on the joint of pipeline 1, should
First pipe box 4 simultaneously movable set in two outer protection tubes 7, in the present embodiment, the first pipe box 4 and the gap of outer protection tube 7 coordinate, institute
State 4 two ends of the first pipe box and be pressed on flexible sealing ring 5 by stretching to installation intracavity, the end of the first pipe box 4；This
In embodiment, the flexible sealing ring 5 offers draw-in groove, the end card of first pipe box 4 in the one end being connected with the first pipe box 4
It is mounted in the draw-in groove, the sealing between the first pipe box 4 and flexible sealing ring 5 is realized by the elasticity of flexible sealing ring 5, works as pipeline
During 1 deformation, the position of the second pipe box 6 changes with the deformation of pipeline 1, now, right due to the elasticity of itself of flexible sealing ring 5
The deflection is recompensed, it is ensured that even if deformation, between the first pipe box 4 and flexible sealing ring 5, between the second pipe box 6 and outer protection tube 7
Sealing, prevents impurity from entering into the joint of pipeline 1 and causes damage, it is ensured that pipeline 1 is normally used.
It is the sealing further between the second pipe box 6 of increase and outer protection tube 7 in the present embodiment, deviates from second pipe box 6
Thermotape 3 is wound between the side of the joint of pipeline 1 and outer protection tube 7.
To improve the heat-insulating property of pipeline 1, described two pipelines 1 are respectively kept with ring-type reserved place, the ring in joint
Shape reserved place outside is provided with shrink wrap layer 2, and the shrink wrap layer 2 is located in the first pipe box 4, and the one side of shrink wrap layer 2 prevents heat by managing
Road joint is lost in, on the one hand because the shrink wrap layer 2 has certain ductility, therefore, the deformation to pipeline 1 equally has compensation
Effect.
The preferred embodiment of the invention is the foregoing is only, it is all at this not to limit the invention
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc. should be included in the invention
Protection domain within.
