Description
Technical Field
The utility model relates to a copper aluminum joint, in particular to a copper aluminum joint for refrigeration equipment.
Background
Many refrigeration plant now adopt copper pipe, the structure that the aluminum pipe is used for the heat transfer pipeline simultaneously, and copper aluminium joint need be used to this kind of structure, but current copper aluminium articulate copper pipe, aluminum pipe are the step more, and the operation is more difficult, and the axis of copper pipe, aluminum pipe is difficult to ensure with the axis that copper aluminium connects on same straight line, and current copper aluminium joint design intensity is lower simultaneously, receives vibration, external force influence drops from the pipeline easily, the reliability is poor.
Disclosure of Invention
The utility model aims at providing a copper aluminium joint for refrigeration plant that structural strength is high, connect copper pipe aluminum pipe simply.
Realize the utility model discloses the technical scheme of purpose as follows:
a copper aluminium connects for refrigeration plant, including the intervalve, suit in intervalve one end and can supply copper pipe male copper connecting pipe and suit in the intervalve other end and can supply aluminum pipe male aluminum connecting pipe, be equipped with a plurality of support rings in copper connecting pipe and the aluminum connecting pipe, the support ring forms the support to copper pipe and aluminum pipe respectively, the tip of intervalve is equipped with a plurality of openings towards the first spread groove of copper connecting pipe and the second spread groove of opening towards the aluminum connecting pipe, be equipped with the brazing filler metal layer in between the support ring, between support ring and the intervalve, first spread groove and the second spread groove, copper pipe, copper connecting pipe, intervalve, aluminum connecting pipe and aluminum pipe are through brazing filler metal layer fixed connection.
After adopting above-mentioned structure, when connecting copper pipe and aluminum pipe, the copper pipe inserts in the copper connecting pipe and supports and lean on the intervalve, and the aluminum pipe inserts in the aluminum connecting pipe and supports and lean on the intervalve, and the support ring plays the effect of support, centering, direction to copper pipe and aluminum pipe for copper pipe, aluminum pipe and copper aluminium connect the coaxial line, then through brazing filler metal braze welding fixed can, simple to operate is quick, the structure of intervalve combination copper connecting pipe and aluminum connecting pipe has improved structural strength and safe and reliable type, the utility model discloses structural strength is high, simple to operate, safe and reliable.
Preferably, for the convenience of installing the copper connecting pipe and the aluminum connecting pipe, the outer wall of the middle pipe is provided with an annular stop block, and one end of the copper connecting pipe and one end of the aluminum connecting pipe are both in contact with the annular stop block.
Preferably, in order to improve the stability of copper connecting pipe and aluminium connecting pipe, the both sides of annular dog all are equipped with a plurality of hemispheric archs, the tip of copper connecting pipe and aluminium connecting pipe all is equipped with a plurality of and the protruding one-to-one's of hemispheric hemispherical concave groove.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a structural view of the intermediate pipe of the present invention.
In the figure: the copper brazing filler metal comprises a middle pipe 1, a copper pipe 2, a copper connecting pipe 3, an aluminum pipe 4, an aluminum connecting pipe 5, a support ring 6, a first connecting groove 7, a second connecting groove 8, a brazing filler metal layer 9, an annular stop block 10, a hemispherical protrusion 11 and a hemispherical groove 12.
Detailed Description
As can be seen from FIGS. 1 and 2, the copper aluminum joint for refrigeration equipment of the present invention comprises an intermediate pipe 1, a copper connecting pipe 3 which is sleeved at one end of the intermediate pipe and can be inserted into a copper pipe 2, and an aluminum connecting pipe 5 which is sleeved at the other end of the intermediate pipe and can be inserted into an aluminum pipe 4, wherein a plurality of support rings 6 are arranged in the copper connecting pipe and the aluminum connecting pipe, the support rings respectively support the copper pipe and the aluminum pipe, the end of the intermediate pipe is provided with a plurality of first connecting grooves 7 whose openings face the copper connecting pipe and a plurality of second connecting grooves 8 whose openings face the aluminum connecting pipe, a brazing filler metal layer 9 is arranged between the support rings, between the support rings and the intermediate pipe, and in the first connecting grooves and the second connecting grooves, the copper pipe, the copper connecting pipe, the intermediate pipe, the aluminum connecting pipe and the aluminum pipe are fixedly connected by brazing filler metal layer, the outer wall of the intermediate, both sides of annular dog all are equipped with a plurality of hemispheric protrusions 11, the tip of copper connecting pipe and aluminium connecting pipe all is equipped with a plurality of and the protruding one-to-one's of hemispheric hemisphere recess 12.
After adopting above-mentioned structure, when connecting copper pipe and aluminum pipe, the copper pipe inserts in the copper connecting pipe and supports and lean on the intervalve, and the aluminum pipe inserts in the aluminum connecting pipe and supports and lean on the intervalve, and the support ring plays the effect of support, centering, direction to copper pipe and aluminum pipe for copper pipe, aluminum pipe and copper aluminium connect the coaxial line, then through brazing filler metal braze welding fixed can, simple to operate is quick, the structure of intervalve combination copper connecting pipe and aluminum connecting pipe has improved structural strength and safe and reliable type, the utility model discloses structural strength is high, simple to operate, safe and reliable.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
