Abstract
The utility model discloses an aluminium joint pipe for air conditioners, which comprises a heat insulation layer pipe wrapped out of the pipe and inner screw joints which are arranged on flanges on both ends of the pipe with enough length. The surfaces of the inner pipe wall and the outer pipe wall of the aluminium joint pipe are provided with protective layer films which are alumina coating films, the alumina coating films with spiral threads or engineering plastic appendage films. Because of the thick quality and corrosion resistance of the alumina coating films or the engineering plastic appendage films, the inner pipe wall and the outer pipe wall of the aluminium joint pipe can not be rusted, and the invention aims of long service life, no or little corrosion and low price are realized. After experiment, the using and operating effect of the aluminium joint pipe is the same as the copper joint pipe.
Description
(1) technical field
The utility model relates to the improvement of air conditioner attachment technique, specifically is a kind of air conditioner aluminium joint pipe, and it belongs to the air conditioner technical field.
(2) background technique
The inside and outside machine machine of the air conditioner of prior art pipe generally all is the copper pipe.This copper connects the machine pipe except costing an arm and a leg, and gets rusty easily in using, and then the corrosion seepage, causes the loss of refrigeration agent.
(3) technology contents
The purpose of this utility model is to provide a kind of cheap, long service life, not or the air conditioner aluminium joint pipe of few corrosion.
Task of the present utility model is finished by following technological scheme, has developed a kind of air conditioner aluminium joint pipe, and it comprises the thermal insulation layer pipe that is wrapped in outside the pipe, is arranged on the female adapter at flange flange place, sufficient length pipe two ends.Inner and outer pipe wall surface at this aluminium joint pipe is provided with the protection tunic.
The described protection tunic of this air conditioner aluminium joint pipe, it is a plating aluminium oxide film, or has the plating aluminium oxide film of spiral lines, or the engineering plastics membrane.
Advantage of the present utility model is: owing to be provided with the protection tunic at the inner and outer pipe wall surface of this aluminium joint pipe.This protects tunic, and it is a plating aluminium oxide film, or has the plating aluminium oxide film of spiral lines, or the engineering plastics membrane.Because plating aluminium oxide film or the matter of engineering plastics membrane are close, corrosion-resistant, make the inner and outer pipe wall surface of this aluminium joint pipe can not realized long service life by corrosion, not or few corrosion, cheap goal of the invention.Through experiment, it is identical that the utilization and operation effect and the copper of aluminium joint pipe connects the machine pipe.
(4) accompanying drawing and embodiment
Embodiment's accompanying drawings of the present utility model is as follows:
Fig. 1 is an air conditioner aluminium joint pipe structural representation.
Fig. 2 is an air conditioner aluminium joint pipe cross-sectional structure schematic representation.
Referring to Fig. 1, the 2 air conditioner aluminium joint pipes of making, external diameter Φ 9.52mm, wall thickness 1mm, it comprises the thermal insulation layer pipe 1 that is wrapped in outside the pipe, is arranged on the female adapter 3 at flange flange 2 places, sufficient length pipe two ends.Inner and outer pipe wall surface at this aluminium joint pipe is provided with protection tunic 4,5.
The described protection tunic 4,5 of this air conditioner aluminium joint pipe, it is a plating aluminium oxide film, or has the plating aluminium oxide film of spiral lines, or the engineering plastics membrane.
This air conditioner aluminium joint pipe is applicable to that the inside and outside machine of all air conditioners connects the usefulness of machine, and its using effect is good.
Claims (2)
1, a kind of air conditioner aluminium joint pipe, it comprises the thermal insulation layer pipe that is wrapped in outside the pipe, is arranged on the female adapter at flange flange place, sufficient length pipe two ends, it is characterized in that: the inner and outer pipe wall surface of this aluminium joint pipe is provided with the protection tunic.
2, according to the described air conditioner aluminium joint pipe of claim 1, it is characterized in that: described protection tunic, it is a plating aluminium oxide film, or has the plating aluminium oxide film of spiral lines, or the engineering plastics membrane.
