Embodiment
Below in conjunction with accompanying drawing 1～6 of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Shown in Fig. 1,2, in a kind of mode of execution of the present utility model, high-performance thermal insulation pipe, comprises, interior steel pipe 10, thermal insulation layer 20 and outer steel pipe 30.Interior steel pipe 10 is working pipe, thermal insulation layer 20, and outer steel pipe 30 is fixed on the outside of interior steel pipe 10 successively.On thermal insulation layer 20, radially offer multiple through holes 21, for making the ventilative more even of thermal insulation layer 20, multiple through holes 21 are distributed in the region of thermal insulation layer 20.Fill and fixing polystyrene foam plastics 22 at through hole 21, polystyrene foam plastics 22 at the two ends of through hole 21, that is, forms polystyrene and fills face 23,24 on the two sides of thermal insulation layer 20.Above-mentioned, the material of thermal insulation layer 20 can be preferably polyurethane heat insulation material.
Therefore,, in the time that interior steel pipe 10 carries out heating power transmission, the aqueous vapor producing can outwards evaporation or mobile smoothly from the through hole of thermal insulation layer 20 21.Avoid producing aqueous vapor in interior steel pipe 10 outsides and the accumulating in a large number of outer steel pipe 30 inner sides, therefore, improved gas permeability and the corrosion resistance of thermal insulation pipe.
For polystyrene foam plastics 22 can better be fixed in through hole 21, as shown in Fig. 3～5, in a kind of mode of execution of the present utility model, the concrete shape of the through hole 21 on thermal insulation layer 20 is taper hole, is oriented the corresponding direction of interior steel pipe 10 sides at the bottom of the cone of taper hole.Thereby, in interior steel pipe 10 processes, after interior steel pipe 10 expands, can further compress by p-poly-phenyl vinylic foam 22, avoid it from through hole 21, to come off.In addition, for polystyrene foam plastics 22 can be better fixed in through hole 21, wire rack 40, in through hole 21, also can be further set.Wire rack 40 is corresponding with hole depth and the aperture of through hole 21, is fixedly connected in through hole 21, is fixedly connected with polystyrene foam plastics.Wire rack 40 can adopt various ways to realize, as adopted the good cage type Stainless Steel Wire rack of distortion.The supporting structure that also can adopt the good supporting frame 41 of fixed effect and wire rack 40 to be mutually permanently connected.Wherein, the concrete shape of the structure of supporting frame 41 and through hole 21 is corresponding.Thereby filled polystyrene foamed plastics 22 in wire rack 40, makes polystyrene foam plastics 22 be fixedly connected in through hole 21 by wire rack 40.The order number of its wire rack 40 is: 10～20 orders.The material of wire rack 40 is stainless steel material.Therefore, make the structure in the utility model more compact, insulation and radiating effect are better.
For making thermal insulation layer 20 more tight with being connected of interior steel pipe 10 and outer steel pipe 30, in a kind of mode of execution of the present utility model, as shown in Figure 6, it is evagination arc shaped surface that its polystyrene is filled face 23,24.Therefore, when interior steel pipe 10 carries out heating power when transmission, along with the outside expansion of interior steel pipe 10 after being heated, arc polystyrene is filled face 23,24 can be on the surface of contact of interior steel pipe 10 and outer steel pipe 30, form multi-point support, thereby, the thermal insulation property of thermal insulation pipe further improved.
Hence one can see that, of the present utility model by offering multiple through holes at the thermal insulation layer of thermal insulation pipe inside, thereby make in thermal insulation layer, and the hot gas of assembling on interior steel pipe can be discharged in time, thereby the aqueous vapor of having improved in interior steel pipe and thermal insulation layer is assembled, reduce the corrosion of internal steel pipe, extended the working life of heating power transfer line, reduced using and keeping in repair of overall heating power transport tube.
The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
