Abstract
The utility model discloses a novel steam straight-buried pipe support structure which comprises a working pipe and an outer casing pipe. An insulating layer is arranged between the working pipe and the outer casing pipe. The novel steam straight-buried pipe support structure is characterized in that a support is arranged between the insulating layer and the outer casing pipe, the support comprises a galvanized steel sheet and a polyfluortetraethylene plate, and the polyfluortetraethylene plate is locked on the galvanized steel sheet. Compared with the prior art, the novel steam straight-buried pipe support structure has the advantages that the support is wrapped on the outer surface of the insulating layer so that no thermal bridge effect exists, material selection is easy, concentricity of the working pipe and the outer casing pipe can be ensured, the requirements for outer sliding of a pipe is well met, and load-bearing of the insulating layer can be relieved.
Description
Technical field
The utility model relates to a kind of Novel steam direct buried pipe supporting structure.
Background technique
At present, in the steam direct-buried conveying technology of domestic thermoelectric industry, inner sliding type heat-insulating structure form adopts the outer slip form of inorganic hard heat insulation layer structure thermal insulating material to adopt the glass wool heat insulation layer structure more more, and in order to reach the purpose of outer slip, commonly used is Steel Bracket.Outer sliding type heat-insulating structure form adopts the glass wool thermal insulation layer more, sums up this structural disadvantages in actual the use as follows: 1. glass wool compressive strength is hanged down and is not possessed supporting effect.Steel Bracket can only be welded on the interior working pipe as supporting, the place of support can not be wrapped up, and affect heat insulation effect, cause local dispel the heat excessive; 2. Steel Bracket directly is welded on the interior working pipe, can cause heat bridge effect, makes outer steel pipe partial excess Temperature, causes hull-skin temperature not reach requirement, also can accelerate the loss of heat in the transportation process; 3. in realizing outer process of sliding, Steel Bracket guide wheel and outer sleeve inner wall friction, self does not have plasticity Steel Bracket, runs for a long time, can affect pipeline working life; 4. Steel Bracket is from the selection to the making, complex process, and cost is higher.
The model utility content
The utility model provides a kind of Novel steam direct buried pipe supporting structure in order to solve the above-mentioned deficiency of prior art.
Above-mentioned purpose of the present utility model realizes by following technological scheme: a kind of Novel steam direct buried pipe supporting structure, comprise working pipe and outer sleeve, be provided with thermal insulation layer between described working pipe and the outer sleeve, it is characterized in that: be provided with support between described thermal insulation layer and the outer sleeve, described support comprises galvanized steel plain sheet and polyfluortetraethylene plate, and described polyfluortetraethylene plate is locked on the galvanized steel plain sheet.
Be provided with vulcanizing silicone rubber between described galvanized steel plain sheet and the polyfluortetraethylene plate.
Described thermal insulation layer comprises inside and outside two-layer, and internal layer is the cotton layer of nanometer, and skin is the phenolic foam layer.
The utility model advantage compared with prior art is:
(1) material of heat-insulating bracket adopts teflon, and is high temperature resistant, and rub resistance can not impact outer sleeve inner wall when guaranteeing outer the slip, can guarantee that also thermal insulation layer can not produce friction and lose efficacy;
(2) the bottom cushion block of support adopts vulcanizing silicone rubber, and the load ability is large, the heatproof rub resistance, and good toughness is arranged, and can guarantee that poling easily advances, also leave another guarantee for the outer sliding friction of pipeline simultaneously;
(3) mode that adopts galvanized steel plain sheet to tie up between support and support.Need only tighten up by rivet, simplify technique, be convenient to dismounting, galvanized steel plain sheet guarantees that well the pressure of outer sleeve is dispersed on each support uniformly simultaneously, is unlikely to damage by pressure to be incubated to deposit, and affects heat insulation effect;
(4) compare with the conventional steel support, support of the present utility model is to be wrapped in the thermal insulation layer outer surface, do not have heat bridge effect, simultaneously selection is easy, can guarantee the concentricity between working pipe and outer sleeve, the outer requirement of sliding of pipeline can well be guaranteed again, the problem of thermal insulation layer load-bearing can also be alleviated.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of Novel steam direct buried pipe supporting structure, comprise working pipe 1 and outer sleeve 2, be provided with thermal insulation layer 3 between described working pipe 1 and the outer sleeve 2, it is characterized in that: be provided with support 4 between described thermal insulation layer 3 and the outer sleeve 2, described support 4 comprises galvanized steel plain sheet 41 and polyfluortetraethylene plate 42, and described polyfluortetraethylene plate 42 is locked on the galvanized steel plain sheet 41, and described galvanized steel plain sheet 41 is around thermal insulation layer 3; Be provided with vulcanizing silicone rubber 43 between described galvanized steel plain sheet 41 and the polyfluortetraethylene plate 42.
Described thermal insulation layer 3 comprises inside and outside two-layer, and internal layer is the cotton layer of nanometer, and skin is the phenolic foam layer.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
