Abstract
The utility model discloses a splicing copper aluminium pipe joint which belongs to a pipe joint. The utility model solves the technical problem that the utility model designs a splicing copper aluminium pipe joint with large contact area and low leakage rate. The utility model has the technical scheme that the splicing copper aluminium pipe joint comprises a copper pipe and an aluminum pipe, and the copper pipe inserted into an aluminum pipe hole is a cone. The utility model is mainly used for connecting pipes of refrigerators, and can also be used in other refrigeration devices.
Description
Technical field:
The utility model relates to a kind of pipe joint, particularly a kind of chiller plant plug-in type copper aluminum pipe joint.
Background technique:
Leak is a big technical barrier of puzzlement refrigerator producer always, and the connection interface in the pipe-line system of refrigerator is the main place that refrigerator leaks, existing pipeline connecting mode is for butt joint and friction is welded or stored energy welding fuses, owing to adopt docking mode, area of contact between copper pipe and the aluminum pipe is little, thereby this joint in use is easy to generate leakage.
Summary of the invention:
The utility model technical issues that need to address are a kind of plug-in type copper aluminum pipe joints of design, and the area of contact of this joint is big, and leak-down rate is low.The technical solution of the utility model is, a kind of plug-in type copper aluminum pipe joint, and it includes copper pipe and aluminum pipe, it is characterized in that: the copper pipe that inserts in the aluminum pipe hole is a cone.The utility model has been owing to taked reducing inserting mode and resistance welding, thus this joint to have area of contact compared with the prior art big, the advantage that leak-down rate is low.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
In conjunction with above accompanying drawing the utility model is elaborated, to need the termination of the copper pipe 3 that connects to shorten one section cone 2 into earlier, can shrinkage cavity in the shrinkage cavity machine, in the hole of 2 sections reeve aluminum pipes 1 of cone of copper pipe 3, intubate also can be undertaken by instrument, because the hardness of aluminum pipe is little than copper pipe, in the copper pipe insertion process, the hole wall of aluminum pipe and copper pipe extrusion-deformation and cone its external diameter that matches is constant, can carry out resistance welding then, makes copper-aluminium tube joint.
