Abstract
The utility model relates to a connecting pipe for an air conditioner. The utility model is composed of a copper pipe and a thermal insulation layer enclosed on the outer side of the copper pipe. The utility model is characterized in that the thermal insulation layer is composed of an inner heat insulating layer and an outer heat insulating layer, wherein, the inner heat insulating layer is arranged on the outer side of the copper pipe. The outer heat insulating layer is arranged on the outer side of the inner heat insulating layer. Furthermore, an embossed film layer is also arranged on the periphery of the outer heat insulating layer. Compared with the prior art, the service life of the utility model is enhanced at least ten years because the utility model adopts a three-layer structure. The utility model has the advantages of outdoor temperature of-50 DEG C-60 DEG C without change of physical properties, ultralow water absorption rate, oil resistance, acid resistance, alkali resistance and chemical corrosion resistance.
Description
Technical field
The utility model relates to a kind of tube equipment, particularly a kind of air conditioner connecting pipe.
Background technique
At present, the open market connecting tube can divide rubber and plastic, EVA, no bridge formation PE etc., but all have many different defectives: temperature tolerance, 80 ℃-90 ℃ of rubber and plastics, EVA, the average heatproof of no bridge formation PE material, can't satisfy the cold coal of novel environment friendly (HRC) the high temperature that produces use for 110 ℃-120 ℃ long-term; Ageing-resistant performance, rubber and plastic, EVA do not have bridge formation PE material and place outdoor mean lifetime 2-3 will produce situations such as face checking, fragmentation, have a strong impact on the air conditioner life-span, increase waste of energy, to influence the city attractive in appearance; Easy construction, open market connecting tube length is 4M-1.8M at present, because of long situation site operation can't penetrate copper pipe, this situation influences speed of application, quality.
Summary of the invention
Technical problem to be solved in the utility model is: because different defectives and deficiency that the air conditioner connecting pipe spare in the existing count word exists aspect temperature tolerance, ageing-resistant performance, easy construction.
The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to provide a kind of air conditioner connecting pipe, constitute by a copper pipe and the thermal insulation layer that is enclosed in the described copper pipe outside, it is characterized in that: described thermal insulation layer is made of inner insulating layer and outer thermal-protective coating, described inner insulating layer is arranged on the outside of described copper pipe, described outer thermal-protective coating is arranged on the outside of described inner insulating layer, further, the periphery of thermal-protective coating also is provided with the stamping foil layer outside described, described inner insulating layer is a water bridge formation polythene material, described water bridge formation polythene material is to make polythene material produce the bridge formation key by a kind of bridging agent, foam performance and resistance to high temperature have so just been improved, increase heatproof than original polythene material and can reach 110-120 ℃, described outer thermal-protective coating is the IXPE polythene material, described IXPE polythene material is by electron accelerator exposure polythene material, make polythene material produce the bridge formation key, changed the performance of original polythene material like this, the periphery of thermal-protective coating also is provided with the stamping foil layer outside described, described stamping foil can be so that air conditioner connecting pipe when bending, makes that the surface is wrinkle resistant, increase attractive in appearance, anti-aging.
The utility model and prior art contrast, because the periphery at copper pipe also is provided with one deck inner insulating layer, described inner insulating layer is a kind of water bridge formation polythene material, can bear the high temperature more than 120 ℃ for a long time, 120 ℃ of runnings in continuous 168 hours, average shrinkage ratio is below 35%, cater to the new cold coal of international environmental protection (HFC) requirement, simultaneously, because the utility model adopts three-decker, thereby improved more than 10 years in the utility model life-span, outdoor temperature-50 does not change rerum natura by ℃-60 ℃, ultralow water absorption rate, but oil resistant, acidproof, alkaline-resisting, chemicals-resistant corrosion.
Description of drawings
Fig. 1 is the structural representation of a kind of air conditioner connecting pipe of the utility model.
Embodiment
As shown in Figure 1, a kind of air conditioner connecting pipe of the utility model, constitute by a copper pipe 1 and the thermal insulation layer that is enclosed in the described copper pipe outside, it is characterized in that: described thermal insulation layer is made of inner insulating layer 2 and outer thermal-protective coating 3, described inner insulating layer 2 is arranged on the outside of described copper pipe 1, described outer thermal-protective coating 3 is arranged on the outside of described inner insulating layer 2, the periphery of thermal-protective coating 3 also is provided with stamping foil layer 4 outside described, described inner insulating layer 2 is a water bridge formation polythene material, described water bridge formation polythene material is to make polythene material produce the bridge formation key by a kind of bridging agent, foam performance and resistance to high temperature have so just been improved, increase heatproof than original polythene material and can reach 110-120 ℃, described outer thermal-protective coating 3 is the IXPE polythene material, described IXPE polythene material is by electron accelerator exposure polythene material, make polythene material produce the bridge formation key, changed the performance of original polythene material like this, described stamping foil 4 can be so that air conditioner connecting pipe when bending, makes that the surface is wrinkle resistant, increase attractive in appearance, anti-aging.
