Description
Technical field
The present invention relates to a kind of air heat insulation (or vacuum heat-insulation) high-temperature pipe fixed support, more particularly to major diameter, remote
The fixation of the high-temperature pipe of distance conveying.The invention further relates to high-temperature pipe fixing means.
Background technology
Conveyance conduit has phenomenon of expanding with heat and contract with cold, therefore pipeline can produce displacement when running into temperature and changing, for
For the major diameter high-temperature pipe (such as more than DN1000) of long-distance sand transport, pipeline because phenomenon of expanding with heat and contract with cold brought it is negative
Influence is bigger, and big displacement, which occurs, for pipeline to be damaged to whole conveyance conduit.To avoid conveyance conduit from occurring big displacement,
Ensure that local weak component is, it is necessary in pipe in the stability of heat supply pipeline pipe-line system under external force, protective conduit system
Sincere buttress is set to carry out pressure fixation to pipeline on certain position in line.In order to which conveyance conduit is fixed, existing skill
It is typically that cement anchor block is set in the relevant position of pipeline in art, using cement anchor block come fixed -piping.But use water
The volume that mud anchor block fixed -piping has anchor block is larger (for example, according to design specification, when heat supply pipeline is DN1000, water
The volume of mud anchor block is 9m3), limited by the space that road piping is integrated, it is impossible to realize, and there is waste of material, cost is high,
Primary concreting is difficult, the defect such as long construction period；In addition, during using cement anchor block fixed -piping, because it is by coagulation
Native buttress and pipeline location ring group are into pipeline location ring is directly contacted with concrete, and the heat of working steel tube can be fixed by pipeline
Position ring is directly conducted to concrete buttress, causes concrete buttress expanded by heating uneven and ruptures, loses the fixation to pipeline
Effect；Further, since the high-temperature pipe of major diameter because the thrust produced by when temperature changes compared to small diameter pipeline its
Produced thrust is bigger, and thrust is up to tens tons, and pipeline fixing bracket of the prior art is often difficult to bear so big
Thrust.
The content of the invention
For the above-mentioned problems in the prior art, the invention provides a kind of new high-temperature pipe fixed support, its
High-temperature pipe can be effectively fixed, is not limited by road piping general space, and load ability is big, can effectively reduce heat bridge
Effect, easy construction, cost are low.
The technical solution adopted for the present invention to solve the technical problems is：A kind of high-temperature pipe fixed support, its it is special it
Place is：Including an outer shroud, two annular inner ring, two outer steel pipes, the outer shroud is main by two blocks of annular side ring plates
And inner ring plate and outer ring plate composition between two blocks of side ring plates are fixedly installed on, two described outer steel pipes are respectively fixedly connected with
In the axial both sides of the outer shroud, the outer shroud and outer steel pipe are sleeved on the outside of working steel tube, and the inner ring suit is simultaneously
The outside of working steel tube is fixed on, two inner ring are respectively positioned at the both sides of the outer shroud and in outer steel pipe, the outer shroud
Thermal insulation layer A is provided between the outer wall of working steel tube, is left between the inner ring and outer shroud and between inner ring and outer steel pipe
Gap, is provided with heat insulation layer B between the outer steel pipe and working steel tube.
In the present invention, because two inner ring and working steel tube are fixed together and can not by the limitation of outer shroud in axial direction
It is moved, so that working steel tube can not be moved, is fixed.The thermal insulation layer A set in the present invention is used to prevent
Heat transfer between working steel tube and outer shroud, prevents outer shroud temperature distortion.In the present invention outer steel pipe and working steel tube it
Between set heat insulation layer B play a part of insulation and support outer steel pipe.Pass through the setting of heat insulation layer, energy
Enough heat transfer effectively blocked between working steel tube and outer shroud and outer steel pipe, can greatly reduce heat bridge effect.
Further, the outside of the outer steel pipe be set with away from the outer shroud certain distance be secured to together plus
Qiang Huan, is fixedly connected with some ribs A between the outer shroud and reinforcing ring.Due to working steel tube meeting when temperature changes
Expand with heat and contract with cold, the outer shroud can be by very big thrust, and the position that outer steel pipe is connected with outer shroud is easy to push away at this
It is broken off in the presence of power, by setting reinforcing ring and ribs A effectively can prevent outer steel pipe from fractureing, it is ensured that fixed support
Use safety；Meanwhile, reinforcing ring is sleeved on outside outer steel pipe, can prevent outer steel pipe from deforming by reinforcing ring.
In order to improve the bulk strength of outer shroud, it is fixedly installed between the inner ring plate and outer ring plate of the outer shroud some uniform
Ribs C.
In order to improve the load ability of inner ring, some uniform reinforcements are fixedly installed between the inner ring and working steel tube
Rib B.
In order to avoid heat transfer, high-strength heat-insulation layer is provided with the gap between the inner ring and outer shroud.
In order to improve the intensity of outer steel pipe, the outer steel pipe outer cover equipped with strengthening steel pipe, the reinforcement steel pipe with
Outer steel pipe and outer shroud are fixedly connected.
Present invention also offers a kind of fixing means of high-temperature pipe, it is to utilize above-mentioned high-temperature pipe fixed support pair
High-temperature pipe is fixed.
The beneficial effects of the invention are as follows：The present invention is simple in construction, and intensity is high, practical using reliable, easy construction,
It can effectively fix high-temperature pipe；Its intensity of the outer shroud of the fabricated structure used in the present invention is high, and load ability is big, can
Larger pipeline thrust is born, major diameter high-temperature pipe is can adapt to because of the high thrust produced by temperature change, and combined type
The outer shroud of structure is easy to process, saves material；The present invention strengthens steel pipe, reinforcing ring, ribs etc. by setting, and is effectively ensured
Support bracket fastened overall construction intensity, so as to ensure that the security of pipe-line system；The present invention is by unique between inner and outer rings
Structure design, using set heat insulation layer, can effectively block the heat of service pipe to outer shroud and outer steel pipe
Conduction, effectively reduces heat bridge effect.Overall structure of the present invention is simple, and small volume is not limited by a space, and cost of the present invention
It is low, it is to use cement using its cost during fixed support in the present invention when same major diameter high-temperature pipe is fixed
/ the 10 of anchor block, therefore, it is possible to substantially reduce construction investment.
