Abstract
The utility model discloses a kind of insulation pipe compensator, be characterized in that FlexbleJoint is sleeved on or is provided with in the pipe fitting overcoat of secondary steel bushing; Described secondary steel bushing is the sleeve pipe that two ends are provided with slope reducing; Described pipe fitting overcoat is straight tube, and secondary steel bushing is sleeved on pipe fitting and puts outward, and its slope reducing is fixedly connected with pipe fitting overcoat, and the interlayer between pipe fitting overcoat and FlexbleJoint and secondary steel bushing is respectively equipped with inner thermal insulating layer and external thermal insulation.The utility model compared with prior art has simple in structure, has eliminated preferably the main outer stress concentration point putting, and has effectively avoided temperature stress to concentrate and the heat distribution pipe network accident that causes, uses and easy for installation, and high insulating effect, greatly reduces the heat waste of pipe network.
Description
technical field
The utility model relates to pipeline heat-insulating technology field, especially a kind of insulation pipe compensator of steel overcoat.
Background technique
The steam line that heat distribution pipeline, especially heat medium temperature are higher, its operating temperature is poor to be reached more than 200 ℃.The working pipe of steam pipe system is mainly made by Common Straight Carbon Steel, and steel have the characteristic of expanding with heat and contract with cold, when pipeline long enough, considerable because of the pipeline elongation that temperature rise heat expansion causes, so be all provided with steam insulation pipe fitting on steam pipe system, compensates.
At present, use the compensator that generally all adopts outer sleeve insulation at the pipe fitting of directly buried installation steam insulation pipe, this insulating structure shape matching is complicated, and especially pipe fitting is enclosed within pipe network axial direction outward and has knuckle.When leakage occurs pipe network, pipe network outer sleeve temperature raises, and the temperature stress producing in outer steel pipe just forms stress and concentrates at knuckle place, and causes the accident generation of heat distribution pipe network.
Model utility content
The purpose of this utility model is a kind of insulation pipe compensator designing for the deficiencies in the prior art, adopt the pipe fitting thermal-insulation coat of major-minor steel sleeve structure, simple in structure, eliminated preferably the main outer stress concentration point putting, the heat distribution pipe network accident of effectively having avoided temperature stress to concentrate and having caused, use and easy for installation, high insulating effect, greatly reduces the heat waste of pipe network.
The purpose of this utility model is achieved in that a kind of insulation pipe compensator, is characterized in that FlexbleJoint is sleeved on or is provided with in the pipe fitting overcoat of secondary steel bushing; Described secondary steel bushing is the sleeve pipe that two ends are provided with slope reducing; Described pipe fitting overcoat is straight tube, and secondary steel bushing is sleeved on pipe fitting and puts outward, and its slope reducing is fixedly connected with pipe fitting overcoat, and the interlayer between pipe fitting overcoat and FlexbleJoint and secondary steel bushing is respectively equipped with inner thermal insulating layer and external thermal insulation.
Described slope reducing internal diameter equates with the external diameter of pipe fitting overcoat.
The utility model compared with prior art has simple in structure, has eliminated preferably the main outer stress concentration point putting, and has effectively avoided temperature stress to concentrate and the heat distribution pipe network accident that causes, uses and easy for installation, and high insulating effect, greatly reduces the heat waste of pipe network.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model is implemented illustration.
Embodiment
Consult accompanying drawing 1, the utility model is comprised of FlexbleJoint 1, inner thermal insulating layer 2, external thermal insulation 4 and the pipe fitting overcoat 3 that is provided with secondary steel bushing 5; Described secondary steel bushing 5 is provided with the sleeve pipe of slope reducing 6 for two ends; Described pipe fitting overcoat 3 is straight tube, and secondary steel bushing 5 is sleeved on pipe fitting overcoat 3, and its slope reducing 6 is fixedly connected with pipe fitting overcoat 3, and the interlayer between pipe fitting overcoat 3 and FlexbleJoint 1 and secondary steel bushing 5 is respectively equipped with inner thermal insulating layer 2 and external thermal insulation 4.The internal diameter of described slope reducing 6 equates with the external diameter of pipe fitting overcoat 3.When the operating temperature of pipe fitting overcoat 3 causes extraordinary temperature stress over design temperature, be arranged on pipe fitting overcoat 3 the pipe network destruction that secondary steel bushing 5 can avoid producing extending stress band is set, greatly eliminated the potential safety hazard of heat supply network.
Consult accompanying drawing 2, the utility model is comprised of FlexbleJoint 1, inner thermal insulating layer 2 and pipe fitting overcoat 3, and pipe fitting overcoat 3 is arranged on outside FlexbleJoint 1; Described inner thermal insulating layer 2 is arranged in the interlayer of pipe fitting overcoat 3 and FlexbleJoint 1, the thermal resistance performance of inner thermal insulating layer 2 should be better than the thermal insulating material that insulation pipe is used, to compensate the thermal insulation property decline of using straight-through rear caused inner thermal insulating layer 2 attenuates of pipe fitting overcoat 3 and causing pipe network.
More than just the utility model is further described, not in order to limit this patent, all is that the utility model equivalence is implemented, within all should being contained in the claim scope of this patent.
