Cold-producing medium tube connector in the existing air-conditioning is copper pipe and links to each other, because copper material price height, makes copper pipe price height, has improved the manufacturing cost of air-conditioning.At present in the tube connector field, the scheme that a lot of material substitutions aspect has been arranged, carbon steel replacement scheme for example, but substituting, carbon steel must solve problem of rustiness, need be coated with corrosion resistant coating, tube interior also will carry out anticorrosion, and product can not be placed in the air too of a specified duration, therefore cause product cost still than higher, have hidden danger of quality simultaneously.Use the product of aluminum pipe replacement scheme to relate to copper and aluminium welding contact processing electrochemical corrosion problem, cause cost too high, the quality instability, life of product is low.
When adopting stainless steel tube with mode that copper pipe links to each other, if the stainless steel tube tube wall is blocked up, then increased the rigidity of stainless-steel pipe, increased material cost.When the stainless steel tube tube wall was thin, its tube wall linked to each other with copper pipe, and it is short to be in contact with one another distance, connect firm inadequately, and when the end of copper pipe linked to each other with the tube wall of stainless steel tube, because the stainless steel tube tube wall is a circular arc, it welded difficulty, welding is burnt the stainless steel tube tube wall easily, weld strength is not high, and influence is used, therefore, existing stainless steel tube links to each other more with copper pipe be that the end links to each other with the end, and this connected mode makes stainless steel tube that certain limitation be arranged when using.
The utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of novel stainless steel pipe tube connector, it is welded on tube connector on the thin wall type stainless steel tube tube wall that can be used in the cold-producing medium connecting line, annular protrusion end face and stainless steel tube planar wall contact-making surface are big and even, its firm welding, and stainless steel tube is cheap, reduced manufacturing cost, be used in the cold-producing medium connecting line, effectively anticorrosion prolongs product service life.
The scheme that the utility model solve the technical problem is:
A kind of novel stainless steel pipe tube connector comprises stainless steel tube and tube connector, forms one or more through hole on the tube wall of described stainless steel tube, and the tube wall of the stainless steel tube around the through hole is shaped to planar wall; Described tube connector forms annular protrusion near on the outer wall of end, and through hole is stretched in the end of tube connector, and the end outer wall of tube connector and the welding of the sidewall of through hole are fixing, and the end face of annular protrusion is weldingly fixed on the planar wall of the stainless steel tube around the through hole.
The end face of described annular protrusion is the plane, it presses and be weldingly fixed on by high silver wire or bronze welding wire on the planar wall of the stainless steel tube around the through hole.
The pipe wall thickness of described stainless steel tube is 0.1～1.0mm; Tube connector is a copper tube.
Described end is for connecting tube head, and its diameter is less than the diameter of tube connector.
Outstanding effect of the present utility model is:
1, it is welded on tube connector on the thin wall type stainless steel tube tube wall that can be used in the cold-producing medium connecting line, annular protrusion end face and stainless steel tube planar wall contact-making surface are big and even, its firm welding, be used in the cold-producing medium connecting line, can reduce the pipeline bending point in the cold-producing medium connecting line, reduced the manufacturing cost of air-conditioning refrigerant connecting line, enhanced productivity.
2, the utility model can replace the connecting line in the existing air-conditioning refrigerant connecting line, and stainless steel is cheap, has reduced the manufacturing cost of air-conditioning refrigerant connecting line, simultaneously, and effectively anticorrosion, prolongation product service life.
