Abstract
The utility model relates to a pipe for connecting an indoor unit and an outdoor unit of an air conditioner. The utility model comprises an aluminum alloy connection pipe section (1), copper connection pipe sections (2, 3), and copper nuts (4, 5), wherein, the copper connection pipe sections (2, 3) are respectively welded on both ends of the aluminum alloy connection pipe section (1). The copper nuts (4, 5) are respectively sheathed at the ends of the copper connection pipe sections (2, 3). Anticorrosive materials (6) is sheathed in a welding position between the copper connection pipe sections (2, 3) and the aluminum alloy connection pipe section (1) or an antiseptic treatment is implemented for the welding position. The utility model has the advantages that a cost is reduced; no corrosion is generated because the copper nuts are contacted with connection valves (or connectors) of the indoor unit and the outdoor unit still by a copper pipe; the connection reliability between connection pipes and the connection valves (or connectors) of the indoor unit and the outdoor unit can be ensured. In addition, the utility model is characterized in that a contact point between aluminium and copper (namely a position where corrosion can be generated) is shifted to the welding position. Then, the antiseptic treatment is implemented for the welding position. Thereby, the problem of galvanic corrosion of an aluminium alloy pipe can be solved. The utilization reliability of the aluminium alloy pipe is enhanced.
Description
1, technical field:
The utility model is a kind of connecting tube that is used for air conditioner indoor and outdoor machine, belongs to the renovation technique of the used connecting tube of air conditioner indoor and outdoor machine.
2, background technique:
The existing used connecting tube of air conditioner indoor and outdoor machine all adopts copper pipe, in copper pipe 2 two ends enlargings and load onto copper nut 4,5, as shown in Figure 1.During installation, copper pipe is connected with the valve (or joint) of indoor and outdoor machine by copper nut.In order to reduce cost, some producer considers to use copper pipe instead the aluminum alloy connecting tube, but, because what air conditioner generally used at present is copper valve (or joint), it must be connected with copper nut, if directly use Al-alloy pipe instead, Al-alloy pipe and copper nut contacting point can produce electrochemical corrosion, thereby cause the joint Al-alloy pipe to be corroded, directly influence its usability.
3, summary of the invention:
The purpose of this utility model is to consider the problems referred to above and provides a kind of both can reduce cost, and can guarantee that again connecting tube is connected the connecting tube that is used for air conditioner indoor and outdoor machine of the connection reliability of valve (or joint) with indoor and outdoor machine.
Structural representation of the present utility model as shown in drawings, include aluminum alloy and connect pipeline section (1), copper connecting tube section (2,3), copper nut (4,5), wherein copper connecting tube section (2,3) is welded on the two ends that aluminum alloy connects pipeline section (1) respectively, and copper nut (4,5) is set in the end of copper connecting tube section (2,3) respectively.
Above-mentioned copper connecting tube section (2,3) is connected pipeline section (1) with aluminum alloy weld is arranged with anti-corrosion material (6) or carries out preservative treatment.
Above-mentioned anti-corrosion material (6) can be heat-shrink tube, and heat-shrink tube is nested with the weld that is connected pipeline section (1) in copper connecting tube section (2,3) with aluminum alloy.
The utility model is owing to adopted the structure of welding a bit of copper connecting tube section at aluminum alloy connection pipeline section two ends, both can reduce cost, again because copper nut is connected the contacted copper pipe that remains of valve (or joint) with indoor and outdoor machine, can not corrode, guarantee that connecting tube is connected the connection reliability of valve (or joint) with indoor and outdoor machine.In addition, the utility model has been transferred to the welding part with the point of contact (i.e. the position that may corrode) of aluminium and copper, again the welding part is carried out preservative treatment, thereby solved the problem of the electrochemical corrosion of Al-alloy pipe, improve the reliability of using the aluminum alloy connecting tube greatly.The utility model is that a kind of design is ingenious, the connecting tube that is used for air conditioner indoor and outdoor machine rational in infrastructure.
4, description of drawings:
Fig. 1 is the structural representation of existing connecting tube;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 connects the sectional view of pipeline section (1) and copper connecting tube section (2,3) joint for the utility model aluminum alloy.
5, embodiment:
Embodiment:
Structural representation of the present utility model is shown in Fig. 2,3, include aluminum alloy and connect pipeline section (1), copper connecting tube section (2,3), copper nut (4,5), wherein copper connecting tube section (2,3) is welded on the two ends that aluminum alloy connects pipeline section (1) respectively, and copper nut (4,5) is set in the end of copper connecting tube section (2,3) respectively.
Above-mentioned copper connecting tube section (2,3) is connected pipeline section (1) with aluminum alloy weld is arranged with anti-corrosion material (6) or carries out preservative treatment.
Above-mentioned anti-corrosion material (6) can be heat-shrink tube, and heat-shrink tube is nested with the weld that is connected pipeline section (1) in copper connecting tube section (2,3) with aluminum alloy.
When the utility model uses, be connected and get final product with the valve (or joint) that is connected of indoor and outdoor machine respectively by copper nut (4,5).
Claims (3)
