Abstract
The utility model relates to the technical field of pipe body connection, and in particular relates to a copper pipe connection structure of a compressor. The connection structure comprises a copper pipe and a compressor housing, wherein one end of the copper pipe is connected with a connecting member which is fixed with the compressor housing; the connecting member is hollow and cylindrical; and one end of the copper pipe is inserted into a middle hole of the connecting member and is fixed by welding by a silver-free solder. As the volume of the connecting member is small, the heat absorbing surface of the connecting member is small, so that heating time is effectively reduced, and the temperature of the surroundings cannot be excessively high; as a result, the connecting member and the copper pipe can be fixed by welding by the silver-free solder, thus cost is reduced, the crystal size of the copper pipe is effectively ensured, and the connecting member and the copper pipe are closely connected so that crack leak cannot occur; as the connecting member is made of an iron material consistent with the compressor housing, cost is low, and by fixing by welding, investment cost is greatly reduced, good tightness is obtained, and the cost performance of a product is improved; and besides, the copper pipe connection structure is simple in structure, scientific, reasonable, easy to make, fit for industrial utilization, and beneficial to enterprise development.
Description
Technical field
The utility model relates to body interconnection technique field, especially relates to the copper pipe syndeton of compressor.
Background technology
Traditional compressor is connected with copper pipe, to offer through hole at compressor housing, and copper pipe is directly to inserting by through hole, then between copper pipe and compressor housing by being welded and fixed, the compressor housing welding of copper pipe and irony, the general silver solder that adopts heats to realize welding by flame, trace it to its cause is because of compressor in the running, reason owing to its deflection axle, the vibration of axial cyclic will occur in compressor, and the part of its most fragile will be the welding position, so welding portion to the grain size number of its copper pipe have obvious specification requirement (industry standard is 0. below 15), if grain size number is excessive, then crackle easily occurs and reveals in copper pipe during vibration of compressor.For reaching its grain size number requirement, its welding material must adopt silver solder, because the fusing point of copper pipe is about 1000 ℃, the fusing point of spelter solder also is between 900 ℃ one 1000 ℃, and as adopting spelter solder, its welding temperature is too high, simultaneously because compressor housing sheet material is thicker, cause copper one iron its heat time heating time in when welding will be very long, cause the grain size number of copper pipe to require to be difficult to guarantee, therefore must adopt and the copper pipe fusing point differs silver solder far away as its welding material.Adopt silver solder, its welding cost is very expensive, is unfavorable for the development of enterprise, also greatly reduces the market competitiveness, requires further improvement for this reason.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of syndeton of improving is provided, and reduces the copper pipe syndeton of the compressor of cost.
For achieving the above object, the utility model adopts following technical scheme:
The copper pipe syndeton of compressor includes copper pipe, compressor housing, an end winding one convergence piece of copper pipe, and convergence piece and compressor housing are fixed together.
Described convergence piece is hollow tube-shape, in the mesopore of the end insertion convergence piece of copper pipe and to be welded and fixed without silver solder; Described convergence piece is embedded in the connecting hole of compressor housing and to be welded and fixed.
One end periphery of described convergence piece is provided with the tapering, holds the tapering that is provided with cone mouth cooperation convergence piece closely to rabbet within the connecting hole of described compressor housing.
The utility model is to increase by a convergence piece grafting between copper pipe and compressor housing, the convergence piece volume is little, thereby heat-absorbent surface is little, effectively shorten heat time heating time, do not allow ambient temperature too high, be welded and fixed thereby can adopt without silver solder between satisfied and the copper pipe, reduce cost, and effectively guarantee the grain size number of copper pipe, connect closely, be difficult for occuring crackle and reveal; And convergence piece adopts the iron material consistent with compressor housing to make, and cost is low, and employing is welded and fixed, thereby greatly reduces cost of investment, also obtain simultaneously good sealing property, the cost performance of improving product, simple in structure, scientific and reasonable, make easily, meet the industry utilization, be beneficial to enterprise development.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model one embodiment;
Accompanying drawing 2 is copper pipe and convergence piece connection diagram.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Consult shown in Fig. 1,2, the copper pipe syndeton of the compressor that the utility model provides includes copper pipe 1, compressor housing 2, an end winding one convergence piece 3 of copper pipe 1, and convergence piece 3 is fixed together with compressor housing 2.The hollow tube-shape that described convergence piece 3 is made for ferrous material, the material consistent with compressor housing made, and easy-formation is made.In the mesopore 31 of the one end insertion convergence piece 3 of copper pipe 1 and to be welded and fixed without silver solder, the insertion end termination of copper pipe 1 is concordant with a termination of convergence piece 3, another termination of convergence piece 3 then is welded and fixed with copper pipe 1, the gap between the mesopore 31 of the corresponding sealing copper pipe 1 of weld part and convergence piece 3.Convergence piece 3 volumes are little, thereby heat-absorbent surface is little, effectively shortens heat time heating time, do not allow ambient temperature too high, be welded and fixed thereby can adopt without silver solder between satisfied and the copper pipe, reduce cost, and effectively guarantee the grain size number of copper pipe, connect closely, be difficult for occuring crackle and reveal.Described convergence piece 3 is embedded in the connecting hole 21 of compressor housing 2 and to be welded and fixed, and this welding can be soldering commonly used, and cost is low.
Shown in Fig. 1,2, an end periphery of described convergence piece 3 is provided with tapering 32, holds the tapering 32 that is provided with cone mouth cooperation convergence piece closely to rabbet within the connecting hole 21 of described compressor housing 2.Utilize the taper interlocking, in conjunction with tightr, sealing is better, promotes serviceability.
The utility model is to increase a convergence piece 3 graftings between copper pipe 1 and compressor housing 2, and convergence piece 3 volumes are little, thereby heat-absorbent surface is little, can effectively shorten heat time heating time, is fit to adopt be welded and fixed without silver solder, greatly reduces cost; And convergence piece 3 adopts iron material to make with compressor housing 2, easy-formation, cost is low, adopts common soldering to fix between the two and gets final product, thereby greatly reduce cost of investment, also obtain simultaneously good sealing property, the cost performance of improving product, simple in structure, scientific and reasonable, make easily, meet the industry utilization, be beneficial to enterprise development.
