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

The dock copper aluminum pipe welded joint
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.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
Embodiment one
As shown in Figure 1, 2, it is a kind of dock copper aluminum pipe welded joint, comprises copper pipe 1 and aluminum pipe 4; 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, the port 2 of copper pipe and the port of aluminum pipe 3 are flat mouthful, and it docks by pressure welding, has formed welding zone 5 in the docking site, copper, aluminium spread mutually in the welding zone, thereby copper, aluminum pipe are connected.This structure does not need that copper pipe and aluminum pipe are had extra processing request or processing, its joint outward appearance radial dimension unanimity, and do not change the internal diameter of pipe, do not influence the flow of connecting tube.
Embodiment two
Shown in Fig. 3,4, it is a kind of dock copper aluminum pipe welded joint, comprises copper pipe 1 and aluminum pipe 4; 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, there is a lead angle 21 port 2 inside of copper pipe, the port 3 outer round platforms 31 that are provided with of aluminum pipe, round platform inserts in the lead angle and by pressure welding and docks, formed welding zone 5 in the docking site, copper, aluminium spread mutually in the welding zone, thereby copper, aluminum pipe are connected.
Embodiment three
Shown in Fig. 5,6, itself and embodiment two are basic identical, and different is to be provided with a round platform 22 outside copper pipe end 2, is provided with a lead angle 32 in aluminum pipe port 3, and round platform inserts in the lead angle.
