Abstract
The utility model discloses a novel composite heat insulation pipe, which comprises a protection layer, a reinforcing layer which is arranged in the protection layer and a heat insulation layer which is arranged between the protection layer and the reinforcing layer. The novel composite heat insulation pipe has the effects of high-temperature resistance and high hardness.
Description
Technical field
The utility model relates to a kind of thermal insulation pipe, particularly a kind of novel composite thermal insulation pipe.
Background technique
At present; The thermal insulation pipe that occurs is on the market mainly formed by PPR (Pentatricopeptide Repeats is atactic copolymerized polypropene again) pipe with in the heat-preservation cotton that the PPR outer tube layer is enclosed with; After using for a long time, find that thermal insulation pipe with this structure is applied to when outdoor, run into when raining moist parcel; Need to use a large amount of glue to be wrapping to heat-preservation cotton on the PPR pipe, so there is the defective of waste glue and complex procedures.To above-mentioned defective, the claimant is in the model utility of application on October 26th, 2010, and name is called " a kind of novel heat insulation pipe ", and the patent No. is 201020579688.0, mainly be by PPR pipe, pvc pipe, and the thermal insulating material between PPR pipe and the pvc pipe is formed.During construction, do not need a large amount of glue just can thermal insulating material be installed between PPR pipe and the pvc pipe.But, cause the problem of the whole fracture of pipe easily because of PPR pipe hardness is not enough.In addition, when PPR pipe inside was passed through as if the water that high heat is arranged, heat resistance was strong inadequately, is prone to deformation defect.
The model utility content
In view of the above problems, the purpose of the utility model is to provide a kind of novel composite thermal insulation pipe.
Be to realize above-mentioned purpose, the utility model provides the novel composite thermal insulation pipe, wherein this pipe intensity layer of comprising protective layer, in protective layer, being provided with, and the thermal insulation layer that between protective layer and intensity layer, is provided with.Structure obtains thus, and the intensity layer has guaranteed that not only thermal insulation pipe integral body is harder, is difficult for breaking off.
In some embodiments, also be included in the refractory layer that the intensity layer is provided with.Structure obtains thus, and refractory layer has guaranteed when high-temperature fluid is passed through thermal insulation pipe, can not be distortion, and high temperature resistant.
In some embodiments, protective layer can be pvc pipe or other tubes of material.Can prevent that thus thermal insulation pipe is aging, can increase the service life.
In some embodiments, thermal insulation layer can be foaming thermal-insulating or fill insulant material.Guaranteed the high insulating effect of thermal insulation pipe thus.
In some embodiments, the intensity layer can be metal layer.
In some embodiments, metal layer can be galvanized pipe or stainless steel and carbon steel pipe or other.Adopt these materials, purpose is the hardness of proof strength layer.
Description of drawings
Fig. 1 is the structural representation of the novel composite thermal insulation pipe of the utility model one mode of execution;
Fig. 2 is a normal section structural representation shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Shown in Fig. 1 to 2, novel composite thermal insulation pipe, wherein this pipe intensity layer 2 of comprising protective layer 1, in protective layer 1, being provided with, and the thermal insulation layer 3 that between protective layer 1 and intensity layer 2, is provided with.In addition, protective layer 1 can be pvc pipe.Thermal insulation layer 3 can be foaming thermal-insulating (for example, polyurethane foam insulation) or fill insulant material.Intensity layer 2 can be metal layer, and metal layer can be galvanized pipe or stainless steel and carbon steel pipe or other.For example if adopt galvanized pipe, have the high characteristics of compressive strength, pressure can reach 16 kilograms.
Identical with embodiment 1 on the structure.Just at the intensity layer 2 inner one deck refractory layer 4 that increases.Refractory layer 4 is to adopt the PE-RT material to process, and can avoid hot water to contact with galvanized pipe effectively, has rust resistance and corrosion resistance, resistant to elevated temperatures characteristics.
During construction, because intensity layer 2 is metal layers, hardness is strong.Can lay the length of thermal insulation pipe arbitrarily.When the water of high temperature passed through, refractory layer 4 not only had the rust resistance and corrosion resistance effect, and has resistant to elevated temperatures characteristics.
Above-described only is some mode of executions of the utility model.For the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
