Utility model content
The purpose of this utility model is to provide a kind of expansion valve of automobile air conditioner connectors, to solve to mention in above-mentioned background technique Existing joint structure out is complicated, and installation is inconvenient, and inner nosepiece wall is easily oxidized, the low problem of service life.
To achieve the above object, the utility model provides the following technical solutions: a kind of expansion valve of automobile air conditioner connector, including Connecting tube, the connecting tube include inner and outer tubes, and the inner wall of said inner tube is coated with polyethylene anti oxidation layer, said inner tube and Enhancement layer and insulating layer are provided between outer tube, and enhancement layer is located at the inner wall of insulating layer, the left and right ends of the connecting tube are equal It is welded with link block, the other end of the link block is welded with sealing flange, is connected with out on the left of the sealing flange of left side Mouthful, be connected with import on the right side of the sealing flange of right side, the inlet and outlet outer wall mutually depending on one end be socketed with sealing Circle.
Preferably, said inner tube and outer tube are stainless-steel pipe.
Preferably, the insulating layer is rock wool heat-preservation layer.
Preferably, the enhancement layer is that two groups of steel wires are formed by connecting, and pass through welded connecting between two groups of steel wires.
Compared with prior art, the utility model has the beneficial effects that the utility model proposes a kind of air conditioning for automobiles is swollen Swollen valve union effectively improves the antioxygenic property of inner tube wall, by the way that Sealing Method is arranged by the way that polyethylene anti oxidation layer is arranged Orchid is fixedly connected it by screw, easy for removal and installation, by setting insulating layer, effectively improves its thermal insulation property, The utility model is structurally reasonable, easy to use, and inner and outer tubes are all made of stainless-steel pipe, effectively prolongs its service life.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model;
Fig. 2 is the side view of the utility model connecting tube.
In figure: 1 connecting tube, 11 inner tubes, 12 outer tubes, 13 polyethylene anti oxidation layers, 14 enhancement layers, 15 insulating layers, 2 connections Block, 3 sealing flanges, 4 imports, 5 outlets, 6 sealing rings.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of expansion valve of automobile air conditioner connector, including even Adapter tube 1, the connecting tube 1 include inner tube 11 and outer tube 12, and the inner wall of said inner tube 11 is coated with polyethylene anti oxidation layer 13, institute It states and is provided with enhancement layer 14 and insulating layer 15 between inner tube 11 and outer tube 12, and enhancement layer 14 is located at the inner wall of insulating layer 15, institute The left and right ends for stating connecting tube 1 are welded with link block 2, and the other end of the link block 2 is welded with sealing flange 3, left side institute The left side for stating sealing flange 3 is connected with outlet 5, and the right side of the right side sealing flange 3 is connected with import 4, the import 4 and goes out Mouthful 5 outer walls mutually depending on one end be socketed with sealing ring 6.
Wherein, said inner tube 11 and outer tube 12 are stainless-steel pipe, effectively improve its corrosion resistance, the insulating layer 15 be rock wool heat-preservation layer, effectively improves its thermal insulation property, the enhancement layer 14 is formed by connecting for two groups of steel wires, and two groups of steel wires By being welded to connect between net, its intensity and hardness are effectively improved, is allowed to be unlikely to deform.
