Abstract
The utility model relates to a butt-joint welded joint for a copper tube and an aluminum tube, which comprises the copper tube and the aluminum tube, and is characterized in that the inside diameter and the outside diameter of the copper tube are the same as the inside diameter and the outside diameter of the aluminum tube; and a port of the copper tube is butted with a port of the aluminum tube through pressure welding to form a welding zone on a butt-joint position. The butt-joint welded joint for the copper tube and the aluminum tube with the structure does not need additionally process or treat the copper tube and the aluminum tube; the radial dimension of the appearance of the butt-joint welded joint for the copper tube and the aluminum tube is consistent; and the inside diameters of the tubes are not changed, and the flow of a connecting tube is not influenced.
Description
Technical field
The utility model relates to a kind of dock copper aluminum pipe welded joint.
Background technique
At present, the welding to the copper aluminum pipe has several different methods, and wherein pressure welding is a kind of technological method of environmental protection practicality.But the present inserting type joint that adopts, for making things convenient for patching of copper pipe and aluminum pipe, must earlier copper pipe one end be closed up, the external diameter after copper pipe closes up can be slightly less than the internal diameter of aluminum pipe, this just causes the internal diameter at copper-aluminium tube joint place, welding back littler than the internal diameter of former pipeline, has influence on the flow of pipeline.
The model utility content
The purpose of this utility model is the shortcoming that overcomes prior art, a kind of dock copper aluminum pipe welded joint is provided, when working pressure welder skill is carried out copper and aluminium welding and is connect, not needing has extra processing request or processing to copper pipe and aluminum pipe, can not change the caliber of copper pipe and aluminum pipe, and can effectively improve the quality of joint.
In order to achieve the above object, the utility model is achieved in that it is a kind of dock copper aluminum pipe welded joint, comprises copper pipe and aluminum pipe; The inside and outside footpath that it is characterized in that the inside and outside footpath of copper pipe and aluminum pipe is all identical, and the port of copper pipe and the port of aluminum pipe dock by pressure welding, have formed the welding zone in the docking site, and copper aluminium spreads mutually in the welding zone.
Be provided with a lead angle in the port of described copper pipe, be provided with a round platform outside the port of described aluminum pipe, round platform inserts in the lead angle and by the pressure welding butt joint, has formed the welding zone in the docking site.
Be provided with a round platform in the port of described copper pipe, be provided with a lead angle outside the port of described aluminum pipe, round platform inserts in the lead angle and by the pressure welding butt joint, has formed the welding zone in the docking site.
The utility model advantage compared with prior art is, not needing has extra processing request or processing to copper pipe and aluminum pipe, and its joint outward appearance radial dimension unanimity does not change the internal diameter of pipe, does not influence the flow of connecting tube.
