Abstract
The utility model discloses a thermal insulation pipe contains at least: the inner pipe body has a certain extending length, a thin pipe layer is coated on the outer surface of the inner pipe body after the inner pipe body is molded, a foaming heat-insulating layer is filled between the thin pipe layer and the outer protection pipe, the foaming heat-insulating layer has proper thickness, so that a proper heat-insulating effect can be generated, the temperature of liquid or gas flowing in the inner pipe body is prevented from being influenced by external temperature, and normal conveying is ensured.
Description
Technical field
The utility model is about thermal insulation pipe, and espespecially a kind of light wall pipe layer that is provided with between interior tube body and insulating foam layer, is prevented that insulating foam layer from directly sticking the surface in interior tube body, so, and when adjacent thermal insulation pipe will overlap; Or to overlap with pipe joint; Or will overlap with other equipment time, when builder removes aforementioned insulating foam layer, removed aforementioned light wall pipe layer simultaneously, to keep the smooth state on interior tube body surface, be able to linking person smoothly.
Background technique
According to known thermal insulation pipe, as the TaiWan, China patent of invention that is entitled as " three-in-one foam insulated pipes " for No. 200424468 disclosed, be mainly coated with foaming layer in the outer surface of inner tube, then establish external pipe in foaming layer outer surface, with foaming material extrusion molding simultaneously.And aforementioned known techniques, because foaming layer is the outside that is directly coated on inner tube, therefore, can directly be attached to the outer surface of inner tube, when builder will overlap adjacent thermal insulation pipe, or thermal insulation pipe and pipe joint are overlapped, or by thermal insulation pipe and other equipment, while overlapping as switch valve, must first external pipe and the foaming layer of part be removed, as aforementioned, because foaming layer meeting is directly attached to the outer surface of inner tube, cause inner tube surface to be stained with the glutinous foam material that has, must be with sand paper to the action of polishing of the outer surface of inner tube, thereby removed, be stained with the foam material sticking in inner tube surface, cause work progress slowly complicated, and through the inner tube of grinding, outer surface is short of well-balanced degree, afterwards, when being connected mutually with adjacent thermal insulation pipe or pipe joint or other equipment, to cause problem closely, this is namely connected the main cause of part seepage.
For this reason, this case inventor, long-pending design and the manufacturing experience of various products for many years, spy is studied for the shortcoming on aforementioned insulation pipe structure, is invention this case again.
Model utility content
The purpose of this utility model is to provide a kind of construction that can promote thermal insulation pipe to be connected speed, can guarantee to be again connected the part structure innovation of the thermal insulation pipe of leakage accidentally.
For reaching aforementioned object; thermal insulation pipe described in the utility model; be the interior tube body in thermal insulation pipe, there is certain extended length, and after interior tube body moulding; again in the coated light wall pipe layer of outer surface of interior tube body; between aforementioned light wall pipe layer and outside protective pipe, be filled with insulating foam layer, aforementioned insulating foam layer also has suitable thickness, is produced suitable heat insulation effect; prevent that extraneous thermal effect from, in the temperature of liquid or the gas of interior tube body internal flow, guaranteeing normal conveying.
Thermal insulation pipe described in the utility model, wherein interior tube body must be plastic tube or metal tube, all without can not.
Accompanying drawing explanation
From to the following description of the preferred embodiments and drawings of purport of the present utility model and use thereof is described, above and other objects, features and advantages of the present utility model will be apparent, in the accompanying drawings:
Fig. 1 is the sectional view of thermal insulation pipe described in the utility model.
Fig. 2 is the setting position view of each element of the utility model.
Fig. 3 is described in the utility model by the film tube of the segment length view separated with inner tube.

Embodiment
So, for making the public be able to fully understand thermal insulation pipe described in the utility model, hereby depend on graphic explanation as follows:
As shown in Fig. 1 and 2; thermal insulation pipe described in the utility model; at least comprise: interior tube body 1; have certain length and extend, aforementioned interior tube body 1 is able to plastic material or metal material by moulding in advance, after aforementioned interior tube body 1 moulding; be able to forming equipment in the coated light wall pipe layer 2 of outer surface 10 of aforementioned interior tube body 1; aforementioned thin layer 2, to be shaped to the best by plastic material, is able to produce with aforementioned thin layer 2 advantage of the outer surface 10 of protection interior tube body 1, prevents that the outer surface of interior tube body 1 is stained.Between aforementioned light wall pipe layer 2 and outside protective pipe 4, be filled with insulating foam layer 3 again; aforementioned insulating foam layer 3 is by PU polyurethane or polyurethane foam material (Polyurethane; be called for short PU) make; or made by PE polyethylene (Polyethylene) foam material; or by PVC PVC＝polyvinyl chloride (Poly Vinyl Chloride; PVC) foam material is made, or is made by other applicable foamed heat insulating materials, all without can not.Aforementioned insulating foam layer 3 also has suitable thickness, is produced suitable heat insulation effect, prevents that extraneous thermal effect is positioned at the temperature of liquid or the gas of interior tube body internal flow, to guarantee the normal conveying of liquid or gas.
As shown in Fig. 3 and 4, thermal insulation pipe described in the utility model, as overlapped adjacent thermal insulation pipe; Or thermal insulation pipe and pipe joint are overlapped; Or thermal insulation pipe and general pipe fitting are overlapped; Or when thermal insulation pipe and other equipment are overlapped; when builder cuts with cutting tool; be able to rapidly aforementioned thin layer 2, insulating foam layer 3 and outside protective pipe 4 be removed in advance; and because be coated with film tube 2 in the outer surface 10 of aforementioned interior tube body 1; therefore; the foam material of aforementioned insulating foam layer 3 can be stained with the outer surface 10 (as shown in Figure 4) sticking in aforementioned interior tube body 1; after removing aforementioned thin layer 2, insulating foam layer 3 and outside protective pipe 4, kept outer surface 10 clean and smooth of aforementioned interior tube body 1.So, after adjacent thermal insulation pipe overlaps; Or after thermal insulation pipe and pipe joint overlap; Or after thermal insulation pipe and general pipe fitting overlap; Or after thermal insulation pipe and other equipment overlaps, the interface position in being connected, is kept optimum engagement state, guarantee that junction point can seepage, and lifting construction speed.
To sum up refer to old, thermal insulation pipe described in the utility model, between interior tube body 1 and insulating foam layer 3, take film tube 2 as intermediary, except guaranteeing the insulation effect of thermal insulation pipe, prevent that thermal insulation pipe is subject to outside the impact of external temperature, more can assure the tightness of joining place, really possess progressive, be the composition of this case.
