Abstract
The utility model discloses a reducing connector-free corrugated connection pipe. The reducing connector-free corrugated connection pipe is of an integrated structure and sequentially comprises a first opening (1), a first corrugated pipe (2), an unthreaded pipe (3), a second corrugated pipe (4) and a second opening (5), wherein the first opening (1), the first corrugated pipe (2), the unthreaded pipe (3), the second corrugated pipe (4) and the second opening (5) are of an integrated structure; the outer diameter of the unthreaded pipe (3) is smaller than the outer diameter of the first corrugated pipe (2) and the outer diameter of the second corrugated pipe (4), the wall thickness of the unthreaded pipe (3) is greater than that of the second corrugated pipe (2) and that of the second corrugated pipe (4), and the transitions among all parts are subjected to arc transitional reducing. The reducing connector-free corrugated connection pipe is of the integrated structure, so that the leakage can be avoided; since the wall thickness of the unthreaded pipe is large and greater than that of the corrugated pipe, the reducing connector-free corrugated connection pipe is unlikely to bend and deform in installation, and the normal circulation of a medium inside the connection pipe can be guaranteed.
Description
Technical field
The utility model relates to copper pipe field, especially relates to a kind of reducing endless corrugated connecting tube and manufacture method thereof.
Background technique
Split-type air conditioner is a kind of very universal household electric appliance, and its indoor units realizes system with outdoor unit by connecting tube and is connected, and the connecting tube typical structure of prior art is equal pipe, and its caliber carries the pipe of refrigerant identical with joined compressor.The restriction of machine structure by compression, the connecting tube caliber of prior art is partially thin, and structural strength is low, and when wiring connects, particularly one section through walls is easily out of shape by bending and reduces the circulation of refrigerant in pipe.At present, in industry, there is a kind of reducing connecting tube to be fitted on split-type air conditioner, by slightly thick one section, be placed on the position being easily out of shape by bending, this structure connecting tube has overcome the shortcoming and defect that waits caliber effectively, but, this kind of reducing connecting tube adopts welding method to realize the pipe connection of different tube diameters, welded joint has the hidden danger of leakage, and when welding the scale that produces of pipe joint inwall be difficult for removing, under the impact of refrigerant stream, scale comes off and sneaks into wherein, easily stops up refrigeration system and causes the accident.In addition, Chinese patent CN200820185933.2 discloses a kind of reducing endless corrugated connecting tube, because its whole wall thickness is identical, if wall is too thick, cost is very expensive, if wall is too thin, when wiring connects, particularly one section through walls is easily out of shape by bending and reduces the circulation of refrigerant in pipe.
Model utility content
The utility model the first object is in order to solve the connecting tube in current split-type air conditioner, caliber is out of shape by bending and reduces the problem of circulation of refrigerant in pipe, a kind of reducing endless corrugated connecting tube is provided, comprise successively the first port one, the first bellows 2, light pipe 3, the second bellows 4 and the second port 5, described the first port one, the first bellows 2, light pipe 3, the second bellows 4 and the second port 5 are structure as a whole; The external diameter of described light pipe 3 is less than the external diameter of the first bellows 2 and the second bellows 4, and the wall thickness of light pipe 3 is greater than the wall thickness of the first bellows 2 and the second bellows 4; Described the first port one dwindles formation by the outer end of the first bellows 2, and the second port 5 dwindles formation by the outer end of the second bellows 4; The transition position of the transition position of the transition position of the transition position of described the first port one and the first bellows 2 outer ends, light pipe 3 and first bellows 2 the inners, light pipe 3 and second bellows 4 the inners and the second bellows 4 outer ends and the second port 5 is all by arc transition reducing.Because the wall thickness of light pipe 3 is larger, when bending, light pipe 3 can not be out of shape, thereby guarantees medium clear.
Wherein, the tube wall of described light pipe 3 is than more than the thickness of pipe wall 0.1mm of the first bellows 2 and the second bellows 4, and the first port one and the second port 5 are horn mouth.Because found through experiments, the tube wall of light pipe 3, than more than the thickness of pipe wall 0.1mm of the first bellows 2 and the second bellows 4, just can be avoided bending distortion better.
The beneficial effects of the utility model are:
Reducing endless corrugated connecting tube in the utility model is structure as a whole, and can not leak, and because the tube wall of light pipe section is thicker, and be greater than the wall thickness of corrugated pipe segment, is therefore difficult for when mounted bending distortion, has guaranteed that in pipe, medium can normally circulate.In view of the tube wall at bellows place thin, thereby guaranteed the raising of bellows place number of bends.
Accompanying drawing explanation
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the schematic diagram of reducing endless corrugated connecting tube in the utility model;
Fig. 2 is the sectional view of reducing endless corrugated connecting tube in the utility model.
