Technical field
The utility model relates to pipe insulation, cold insulation technical field, specifically telescopic thermal insulation pipe.
Background technique
Thermal insulation pipe is widely applied to city thermal pipeline, crude oil pipeline, on the pipeline of natural-gas transfer pipeline and central air-conditioner.On market today, common pipeline is incubated, cold insulation mainly contains two kinds of patterns.
The first pattern is prefabricated direct-buried jacket (high density polyethylene (HDPE)) thermal insulation pipe.Mainly be enclosed within outside medium pipeline by black yellow jacket leather, and then inject the structure that polyurethane foam material carries out as thermal insulating material being incubated in centre.This structural advantages is: thermal insulation layer and medium pipeline are built integral, and sealing thermal insulation is effective, can effective corrosion-resistant thermal insulation; Jacket leather is moistureproof, and Anti-moth-eating is antirust.Shortcoming is the sun-proof poor performance of jacket leather, and fire-protection rating is low, and when UV sunlight is tanned by the sun, working life is short.Due to the insufficient strength of jacket, causing can not pressure-bearing, thus thermal insulating material density is not reached, and cold insulation function cannot be ensured.
The second is shell of pipe type (having another name called tile type).Heat-insulation system.Need a point two-layer construction, outer brushing matizhi when protecting ultralow temperature pipeline, as vapor barrier, and then metallized aluminum skin is as protective layer.Advantage to adapt to building site demand, after pipeline construction, carry out heat preservation construction again.But the method formality is loaded down with trivial details, executes man-hour requirement seven road formality and just can complete whole construction.Because need to construct at the scene, because the material such as matizhi, adhesive can cause secondary pollution to scene, also need to clear up, cause the increase of expense; Because just can isothermal holding be done after needing construction technology to complete, so can total time of construction be extended; Need gap to be processed many, the crack etc. between vertical masonry joint, circumferential weld, two-layer shell simultaneously, have process situation not in place unavoidably and occur, cold draining leakage enthusiasm condition can be caused, insulation cold insulation effect is had a greatly reduced quality; Site operation, can cause personnel, material, tool for subsequent use come and go etc. expense; In some cases, as the situation such as high-lift operation, pit work, insulation, cold insulation construction get up expense comparatively greatly, and risk factor is high, long in time limit.
Model utility content
The utility model, in order to solve the problems of the technologies described above, provides a kind of novel structure, easy and simple to handle, time saving and energy saving, insulation, the effective telescopic thermal insulation pipe of one of cold insulation.
To achieve these goals, the utility model provides telescopic thermal insulation pipe, thermal insulation pipe comprises the tubular thermal insulation layer of hollow, protective coating is enclosed with outside thermal insulation layer, described thermal insulation layer one end is provided with female part, its the other end is provided with the insertion part corresponding to described female part, and described protective coating is stainless steel or carbon steel.

Embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and working principle are described in detail: as Figure 1-4, the telescopic thermal insulation pipe of the utility model, thermal insulation pipe comprises the tubular thermal insulation layer 2 of hollow, protective coating 1 is enclosed with outside thermal insulation layer 2, described thermal insulation layer 2 one end is provided with female part 3, and its other end is provided with the insertion part 4 corresponding to described female part 3.
According to the needs of actual duct length, thermal insulation pipe can use one or more, in time using many, needs the female part 3 of a thermal insulation layer to dock with the insertion part 4 of another root thermal insulation layer 2.
The internal diameter of pipe hole 5 designs in advance according to outer diameter tube, and the internal diameter of pipe hole 5 is greater than the external diameter 1-4mm of pipeline.
First embodiment is as follows: the annular projection of female part 3 we select annular projection shaft section outer rim to be the annular projection parallel with axle, as shown in Figure 2, the internal diameter of pipe hole 5 is greater than the external diameter 2mm of pipeline, axially external force is applied to thermal insulation pipe during Specific construction, thermal insulation pipe is pushed in pipeline from pipe hole 5, then, again another root thermal insulation pipe is also pushed in pipeline, and ensure that its insertion part 4 connects with the female part 3 of another root thermal insulation layer 2 pushed before, because this structure just has circumferential weld two thermal insulation pipe junctions, ensure that the medium temperature in pipeline is scattered and disappeared minimum, also be provided with cushion two thermal insulation pipe junctions, the first-selected PEF cushion of cushion, can avoid the appearance of the flexible annular vertical masonry joint that pipeline contraction or expansion produces when pipe temperature changes like this, finally stick with glue agent at two thermal insulation pipes in conjunction with gap place more bonding, make the thermal insulation pipe coupled together form the splendid integral heat insulation system of sealing, thus greatly improve insulating efficiency.In order to improve life-span and heat insulation effect further, being also provided with seal ring two thermal insulation pipe protective coating 1 junctions, the protective coating 1 of seal ring and two thermal insulation pipes being welded together, effectively extends pipeline life and sealability.Condition of construction according to scene can to the length combination in any of thermal insulation pipe, easy construction.
