One exempts from welded formula expansion valve connecting tube, including air-conditioning inlet pipe, air-conditioning go out pipe, inlet pipe docking nipple and
Going out pipe docking nipple, one end of described air-conditioning inlet pipe and described air-conditioning go out one end of pipe and connect by locking pressure plate is fixing,
Described air-conditioning inlet pipe and air-conditioning go out pipe and are all connected by screw is fixing with between locking pressure plate, and described air-conditioning inlet pipe is away from locking
One end of pressing plate is provided with inlet pipe riveted structure, and described air-conditioning inlet pipe is provided with into tube seal structure, institute near one end of locking pressure plate
Stating air-conditioning to go out pipe and be provided with out pipe riveted structure away from one end of locking pressure plate, described air-conditioning goes out pipe and sets near one end of locking pressure plate
There is discharge pipe sealing structure；Described inlet pipe docking nipple and the inside going out pipe docking nipple are respectively equipped with and inlet pipe rivets
Structure and go out riveted structure one and the riveted structure two that pipe riveted structure matches.
Further, described air-conditioning inlet pipe and air-conditioning go out pipe and are the aluminum pipe of Φ 16*1.2mm.
The beneficial effects of the utility model: air-conditioning inlet pipe and air-conditioning go out pipe and use riveting form, locking with nipple
Pressing plate and air-conditioning inlet pipe and air-conditioning go out employing screw type of attachment between pipe, and the improvement of said structure instead of traditional Welder
Skill, improves the air-tightness of pipeline, decreases material, improve product quality, facilitates replacing and the installation in pipeline later stage, and
The maintenance cost in pipeline later stage and the replacing number of times of product can be reduced.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
The accompanying drawing used required in is briefly described, it should be apparent that, the accompanying drawing in describing below is the most of the present utility model
Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to according to this
A little accompanying drawings obtain other accompanying drawing.
Fig. 1 is according to the structural representation exempting from welded formula expansion valve connecting tube described in this utility model embodiment.
In figure:
1, air-conditioning inlet pipe；2, inlet pipe riveted structure；3, inlet pipe docking nipple；4, air-conditioning goes out pipe；5, pipe riveting knot is gone out
Structure；6, pipe docking nipple is gone out；7, inlet pipe Butt sealing structure；8, locking pressure plate；9, discharge pipe sealing structure.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained, all belong to
Scope in this utility model protection.
As it is shown in figure 1, exempt from welded formula expansion valve connecting tube according to the one described in embodiment of the present utility model, bag
Include air-conditioning inlet pipe 1, air-conditioning goes out pipe 4, inlet pipe docks nipple 3 and go out pipe docking nipple 6, the one of described air-conditioning inlet pipe 1
End and described air-conditioning go out one end of pipe 4 and connect by locking pressure plate 8 is fixing, and described air-conditioning inlet pipe 1 and air-conditioning go out pipe 4 and locking
All connecting by screw is fixing between pressing plate 8, described air-conditioning inlet pipe 1 is provided with inlet pipe riveted structure away from one end of locking pressure plate 8
2, described air-conditioning inlet pipe 1 is provided with near one end of locking pressure plate 8 into tube seal structure 7, and described air-conditioning goes out pipe 4 away from locking pressure plate
One end of 8 is provided with out pipe riveted structure 5, and described air-conditioning goes out pipe 4 and is provided with discharge pipe sealing structure 9 near one end of locking pressure plate 8；Institute
State inlet pipe docking nipple 3 and go out the inside of pipe docking nipple 6 and be respectively equipped with and inlet pipe riveted structure 2 and go out pipe and rivet
Riveted structure one that structure 5 matches and riveted structure two.
In a specific embodiment, described air-conditioning inlet pipe 1 and air-conditioning go out pipe 4 and are the aluminum pipe of Φ 16*1.2mm.
When specifically used, structurally inlet pipe docking nipple 3 and the making going out pipe docking nipple 6 use riveting
Connect formula, by three-dimensional termination equipment inlet pipe docked nipple 3 and go out pipe docking nipple 6 respectively with inlet pipe riveted structure
