Abstract

The invention discloses a reducing pipeline part of an air conditioning system. The reducing pipeline part of the air conditioning system is an integral reducing pipeline part, accordingly, the various quality problems of welding blockage or welding leakage and the like of the pipeline part due to welding in the prior art are effectively avoided, and the product quality is improved; and moreover, compared with the prior art in which the processing process of flaring or necking is performed at first, and then welding and annealing are performed, the reducing pipeline part of the air conditioning system disclosed by the invention is the integral reducing pipeline part, and only a drawing process and the annealing process are needed or only the flaring process is needed, so the processing processes of the reducing pipeline part are relatively less, and accordingly, the production efficiency is increased.

Description

A kind of air-conditioning system reducing pipeline fitting

Technical field

The present invention relates to field of air conditioning, particularly a kind of air-conditioning system reducing pipeline fitting.

Background technique

Air conditioner is in design process, and is optimum in order to make complete machine refrigeration performance and heating performance, and Energy Efficiency Ratio is the highest, and the whole system pipeline need to be mated by the pipe fitting of a plurality of different tube diameters, to form air-conditioning system reducing pipeline fitting.For example, arm in the pipeline fitting such as liquid collecting pipe or liquide separating tube, namely mate each other for the copper pipe by different tube diameters and the air-conditioning system reducing pipeline fitting through being welded, as shown in Figure 1, mate respectively the relatively large capillary tube of caliber at the two ends of capillary tube 1 and go out pipe 2, and connect by the mode with tie point welding, its manufacturing process sees also Fig. 2.

But, make by this kind mode and to obtain system pipeline spare and have following drawback: connect needs between the copper pipe of different tube diameters and adopt gas brazing to weld, through the place of welding, namely easily there is the hidden danger that weldering is stifled or weldering is leaked qualitatively in soldering point 3, thereby brings impact to quality of product; Each tie point need to manually carry out gas brazing, and manufacturing efficiency is low, and simultaneously, welding surroundings also has certain negative effect to employee's health; In order to guarantee welding quality, also need the employee to utilize equipment butt welding contact 3 before welding, to carry out expanding or reducing processing, as seen, its manufacturing procedure is more, and manufacturing efficiency is low.

Therefore, how reducing the system pipeline spare of air conditioner because the various hidden danger of quality that cause of welding, improving the quality of products, and how to reduce manufacturing procedure to enhance productivity, is the technical problem that those skilled in the art need to be resolved hurrily.

Summary of the invention

In view of this, the invention provides a kind of air-conditioning system reducing pipeline fitting, its integrated reducing pipeline fitting, thereby Effective Raise quality of product, reduced manufacturing procedure.

For achieving the above object, the invention provides following technological scheme:

A kind of air-conditioning system reducing pipeline fitting, the integrated reducing pipeline fitting of described air-conditioning system reducing pipeline fitting.

Preferably, in above-mentioned air-conditioning system reducing pipeline fitting, described integrated reducing pipeline fitting forms through drawing process and annealing process manufacturing.

Preferably, in above-mentioned air-conditioning system reducing pipeline fitting, manufacturing forms described integrated reducing pipeline fitting through enlarging technique.
