Abstract
The utility model discloses a large pipe diameter heat supply pipeline with movable core pipes. The large pipe diameter heat supply pipeline comprises the core pipes positioned inside the pipeline, wherein a heat preservation layer is arranged on the outer side of each core pipe; a protective pipe is arranged on the outer side of each heat preservation layer; support frames are fixed on the outer sides of the core pipes at intervals; steel balls are distributed on the peripheries of the support frames in the circumferential direction; the protector pipes are supported by the steel balls. As each core pipe and each protective pipe on the outer side are relatively supported through supporting components, the heat preservation layer between each core pipe and each protective pipe is free of the gravity action of an inner pipe and an outer pipe and is effectively protected, the defect that the heat preservation layers under stress are easily damaged is overcome, the service life of the pipeline is prolonged, the overall structure is simple, and the assembling is convenient; besides, the core pipes can slightly move or rotate relative to the protective pipes on the outer sides through the steel balls after being subjected to thermal expansion, so that the structure of the pipeline is further effectively protected.
Description
Technical field
The utility model relates to a kind of structure of pipeline, particularly the movable Large Diameter Pipeline heat supply pipeline of a kind of core pipe.
Background technique
Heat supply pipeline mainly contains two kinds at present, and a kind of is the heat supply pipeline hanging in the sky by suspender member or supporting element, and another kind is that direct-burried is in underground heat supply pipeline.Usually said Large Diameter Pipeline heat supply pipeline refers to the pipeline of defeated heat pipe diameter more than 800 millimeters.The structure of this pipeline is that inside has a core pipe for defeated heat, has thermal insulation layer in core pipe outside, and there is protective tube in thermal insulation layer outside, and in order there to be good heat insulation effect, what have arranges multi-layer heat preserving.The pipeline of this structure due between each layer mutually continuously, between core pipe and outermost protective tube, support by thermal insulation layer, make thermal insulation layer stressed, in use easily damage, affected heat insulation effect, the while has also affected the working life of pipeline.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, thermal insulation layer does not stress, core pipe can relatively rotate and move with respect to outside protective tube, improve the movable Large Diameter Pipeline heat supply pipeline of core pipe in working life, overcome the deficiencies in the prior art.
The movable Large Diameter Pipeline heat supply pipeline of core pipe of the present utility model; comprise and be positioned at inner core pipe; outside at core pipe is provided with thermal insulation layer; outside at thermal insulation layer is provided with protective tube; outside core pipe, interval is fixed with supporting frame; periphery at supporting frame is along the circumferential direction distributed with steel ball, and described protective tube supports by each steel ball.
Described supporting frame comprises the retaining ring being welded on core pipe; on retaining ring excircle, be welded with two parallel support plates; between two parallel support plates, be welded with the intermediate plate of band gear platform; described steel ball is positioned on intermediate plate; described support plate, intermediate plate, steel ball has four groups and be uniformly distributed along the circumferencial direction of retaining ring, between thermal insulation layer and protective tube, has air layer.
The movable Large Diameter Pipeline heat supply pipeline of core pipe of the present utility model; owing to carrying out relative support by supporting part between core pipe and the protective tube in outside; make the do not stress effect of inner and outer pipes gravity of thermal insulation layer between core pipe and protective tube; effectively protect thermal insulation layer; overcome the drawback of the stressed rapid wear of thermal insulation layer; in the working life of having improved pipeline, overall structure is simple, easy to assembly.After core pipe expanded by heating, can there is relatively moving or rotating of trace with respect to outside protective tube by steel ball in addition, further effectively protect the structure of pipeline.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A section enlarged diagram shown in Fig. 1.
Embodiment
As shown in Figure 1, 2: 1 is core pipe, is provided with thermal insulation layer 2 in the outside of core pipe 1, and thermal insulation layer 2 can be multilayer, selects as required different thermal insulating materials that multilayer is set and is incubated.Be provided with protective tube 3 in the outside of thermal insulation layer 2.
Be fixed with multiple supporting frames at core pipe 1 interval, outside, be along the circumferential direction distributed with steel ball 5 at the periphery of supporting frame, protective tube 3 supports by each steel ball 5, between core pipe 1 and protective tube 3, utilizes spaced multiple supporting part to keep relative and coaxially arranges.
Supporting frame comprises the retaining ring 8 being welded on core pipe 1, is welded with two parallel support plates 7 on retaining ring 8 excircles, is welded with the intermediate plate 6 of band gear platform 9 between two parallel support plates 7, and steel ball 5 is positioned on intermediate plate 6, and both sides have gear platform 9 to stop.Support plate 7, intermediate plate 6, steel ball 5 have four groups and be uniformly distributed along the circumferencial direction of retaining ring 8, form supporting frame.Between thermal insulation layer 2 and protective tube 3, there is air layer 4, further improve heat insulation effect.
Between protective tube 3 due to core pipe 1 and outside, carry out relative support by supporting part; make the do not stress effect of inner and outer pipes gravity of thermal insulation layer 2 between core pipe 1 and protective tube 3; effectively protect thermal insulation layer 2; overcome the drawback of thermal insulation layer 2 stressed rapid wears; improve the working life of pipeline; overall structure is simple, easy to assembly.After core pipe 1 expanded by heating, can there is micro-distortion with respect to outside protective tube 3 by steel ball 5 in addition, further effectively protect the structure of pipeline.
