Abstract
The utility model discloses an use muffler in air conditioning equipment, whole shaping has a sleeve pipe of the copper pipe that is used for plugging into on the muffler, and the whole shaping of sheathed tube inner wall has and supplies the copper pipe to support the boss that leans on on it. This muffler can guarantee that the copper pipe is overlapping the intraductal sufficient degree of depth that has, has improved the sealed firm nature between muffler and the copper pipe from this, has improved welding quality when welding copper pipe. If stainless steel material makes for the muffler, more showing welding quality's improvement.
Description
Technical field
This utility model relates to the deafener applied in air-conditioning equipment.
Background technology
Apply the deafener in air-conditioning equipment, install in refrigerant line system.This kind of deafener needs
Copper pipe is welded at its sleeve pipe.In the prior art, the internal surface of sleeve pipe of this kind of deafener is the smooth face of cylinder,
The degree of depth that copper pipe inserts sleeve pipe is wayward, and the gap between internal surface of sleeve pipe and copper pipe is narrow and small, welding
During solder be difficult to be deep in sleeve pipe, cause the sealing between deafener and copper pipe the most firm,
It is susceptible to cold-producing medium leakage.If deafener stainless steel material is made, between deafener and copper pipe more
Add and be difficult to solder to, seal illusive defect more prominent.
Utility model content
The purpose of this utility model is to provide a kind of deafener applied in air-conditioning equipment, and this deafener can
Improve the quality welded with copper pipe.
This utility model is achieved in that a kind of deafener applied in air-conditioning equipment, at deafener
Upper global formation has to plug into the sleeve pipe of copper pipe, and the inwall global formation of sleeve pipe has and is resisted against it for copper pipe
On boss.
As preferred forms, described sleeve pipe is that internal diameter is tapered to be gradually reduced in sleeve pipe from sleeve pipe
Pipe.
The inwall cone angle of described sleeve pipe is 0.4 °～0.7 °.
The internal diameter of the small-caliber end of described sleeve pipe is less than the external diameter of the copper pipe plugged into so that be resisted against described
Copper pipe on boss forms interference fit, the internal diameter of the heavy caliber end of described sleeve pipe with the small-caliber end of sleeve pipe
Bigger than the external diameter of the copper pipe plugged into.
The utility model has the advantages that, the boss of the internal surface of sleeve pipe of deafener plays positioning action, in welding
During copper pipe, as long as copper pipe being injected sleeve pipe until being resisted against on boss, it is ensured that copper pipe has in sleeve pipe
Enough degree of depth, thus ensure that the sealing fixing between deafener and copper pipe, improve welding quality.
If deafener stainless steel material is made, the improvement of welding quality is the most notable.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the A portion cutaway view Amplified image of Fig. 1；
Fig. 3 is the schematic diagram after the sleeve pipe insertion copper pipe of deafener.
Detailed description of the invention
See Fig. 1, a kind of deafener applied in air-conditioning equipment provided according to this utility model, bag
Include two sleeve pipes 1,2 in order to copper pipe of plugging into.Two sleeve pipes are all global formations on deafener 3.Two
The structure of individual sleeve pipe 1,2 is identical.As a example by one of them sleeve pipe 1, see Fig. 2, sleeve pipe 1 interior
Wall global formation has confession copper pipe to be resisted against boss 4 thereon.When welding copper pipe, as it is shown on figure 3, only
Copper pipe 5 is injected sleeve pipe until being resisted against on boss 4, it is ensured that copper pipe 5 has foot in sleeve pipe 1
Enough degree of depth.
As preferred forms, sleeve pipe 1 is that one section of internal diameter is gradually reduced gradually from sleeve pipe in sleeve pipe
The draw.As in figure 2 it is shown, the inwall cone angle beta of sleeve pipe 1 is preferably 0.4 °～0.7 °.Sleeve pipe 1 uses
Reducing pipe structure so that the solder of fusing is easy to deeply flow in sleeve pipe, makes internal surface of sleeve pipe and copper pipe
Between gap uniformity ground be full of solder.The internal diameter of the small-caliber end of sleeve pipe 1 most cans be compared to plugged into copper pipe
Smaller about the 0.02mm of external diameter of 5 so that the copper pipe 5 being resisted against on boss 4 is small-bore with sleeve pipe 1
End forms interference fit, close-fitting when ensureing assemble welding with this, will not dislocate.The heavy caliber end of sleeve pipe 1
Internal diameter can be compared to most bigger about the 0.1mm of external diameter of plugged into copper pipe 5, be beneficial to solder infiltration.This
Section is as a example by sleeve pipe 1, and described structure is equally applicable to sleeve pipe 2.
Whole deafener 3 can be processed by flow forming and molding process with hollow stainless steel tube.Utilize spinning
Cylindrical stainless steel pipe rolling is become the shape shown in Fig. 1 by the roller of forming machine, formed two sleeve pipes 1,
2, and in rolling process, utilize a plug inserting stainless steel tube so that two sets formed
Pipe 1,2 is rolled into the structure shown in Fig. 2 between roller and plug, forms boss 4 and cone angle is β
Reducing pipe.
In actual production, can resale after integrally welded to copper pipe and deafener.
Above-described embodiment is preferred embodiment of the present utility model, all structures similar with this utility model and
The equivalence change made, all should belong to protection category of the present utility model.
