Abstract
The invention relates to an air conditioner connecting pipe structure. The air conditioner connecting pipe structure comprises a copper pipe, an aluminum pipe, pipe joints and a heat insulating sleeve, wherein a joint is arranged at a welded position between the copper pipe and the aluminum pipe and comprises an outer sleeve and an inner sleeve, one end of the inner sleeve is connected with the copper pipe in a sealed manner, and the wall of the end part of the aluminum pipe is clamped between the outer sleeve and the inner sleeve. The air conditioner connecting pipe structure has the advantages of convenience in connection and reliable performance.
Description
Technical field
The present invention relates to a kind of air conditioner connecting pipe structure.
Background technique
Air conditioner connecting pipe is the pipe connected between air conditioner outdoor machine and indoor set, and its effect is mainly the passage of refrigerant circulation between indoor apparatus of air conditioner and outdoor unit.The air conditioner connecting pipe used at present, its structure is: comprise copper pipe, pipe joint, thermal insulation casing, pipe joint is arranged on the end of copper pipe, and thermal insulation casing is sleeved on the outside of copper pipe, also is set with the protection spring on copper pipe.The air conditioner connecting pipe of this structure is by the protective action of protection spring, and in the assembly process of air conditioner, copper pipe is not easy flatly to fall, and has both facilitated the installation of connecting tube, has stopped again to descend because of the heat pump performance that the connecting tube distortion causes.
Because above-mentioned copper pipe adopts the red copper manufacture with, red copper has good corrosion resistance, but cost is higher, in order to reduce manufacture cost, some copper pipes adopt metal composite pipe to replace the stage casing body of air conditioner connecting pipe, effectively reduce the copper consumption, save cost, as the stage casing body adopts aluminum pipe, tube head adopts copper pipe, between aluminum pipe and copper pipe, adopts welding technique to be connected.But the situations such as solder skip, rosin joint appear in welding unavoidably, cause coolant leakage, and also more inconvenient when body aging needs in stage casing are changed.
Summary of the invention
For above-mentioned technical problem, main purpose of the present invention is for providing a kind of air conditioner connecting pipe structure of easy to connect, reliable performance.
The technological scheme solved the problems of the technologies described above is as follows:
The air conditioner connecting pipe structure, comprise copper pipe, aluminum pipe, pipe joint, thermal insulation casing, copper pipe and Al pipe butt welding are fixed, pipe joint is arranged on the end of copper pipe, thermal insulation casing be set in copper pipe and outside, be provided with a joint at the weld of copper pipe and aluminum pipe, described joint comprises overcoat and inner sleeve, the described inner sleeve one end described copper pipe that is tightly connected, the end tube wall of described aluminum pipe is clamped between described overcoat and described inner sleeve.
Adopted such scheme, adopted joint to connect copper pipe and the aluminum pipe of air conditioner connecting pipe, there is flexible operation, connect characteristics reliable, good seal performance, when aluminum pipe is aging while needing to change, also can very easily it have been disassembled.
Further, the outer surface of described inner sleeve is comprised of conical surface and cylndrical surface, cylndrical surface is provided with screw thread, pressure pipe is positioned on the conical surface of inner sleeve and aluminum pipe is pushed down, the internal surface of described overcoat is comprised of conical surface section and cylinder section, the cylinder section is provided with internal thread, the internal thread put outward with in the outside thread that puts interconnect, the conical surface section put is outward pushed down described pressure pipe.When rotary sleeve is threaded with inner sleeve, along with the displacement of overcoat, the conical surface section of overcoat is put with pressure pressure pipe, and pressure pipe presses to aluminum pipe like this, thereby aluminum pipe is clamped between overcoat and inner sleeve tightly.
Further, be set with spring on copper pipe and aluminum pipe.By the protective action of spring, in the assembly process of air conditioner, copper pipe is not easy flatly to fall, and has both facilitated the installation of connecting tube, has stopped again to descend because of the heat pump performance that the connecting tube distortion causes.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
1 is copper pipe, and 2 is aluminum pipe, and 3 is pipe joint, and 4 is thermal insulation casing, and 5 is overcoat, and 6 is inner sleeve, and 7 is pressure pipe, and 8 is spring.
Embodiment
With reference to Fig. 1, a kind of air conditioner connecting pipe structure of the present invention, comprise copper pipe 1, aluminum pipe 2, pipe joint 3, thermal insulation casing 4.Copper pipe 1 is welded and fixed with aluminum pipe 2, and pipe joint 3 is arranged on the end of copper pipe 1, thermal insulation casing 4 be set in copper pipe and outside.Be set with spring 8 on copper pipe 1 and aluminum pipe 2, thermal insulation casing 4 is enclosed within the outer surface of spring 8.Weld at copper pipe and aluminum pipe is provided with a joint, and described joint comprises overcoat 5 and inner sleeve 6, the described inner sleeve 6 one ends described copper pipe 1 that is tightly connected, and the end tube wall of described aluminum pipe 2 is clamped between described overcoat 5 and described inner sleeve 6.The outer surface of described inner sleeve 6 is comprised of conical surface and cylndrical surface, and cylndrical surface is provided with screw thread, and pressure pipe 7 is positioned on the conical surface of inner sleeve and aluminum pipe is pushed down.The internal surface of described overcoat 5 is comprised of conical surface section and cylinder section, and the cylinder section is provided with internal thread, the internal thread put outward with in the outside thread that puts interconnect, the conical surface section put is outward pushed down described pressure pipe 7.
