Embodiment Construction

[0008] Solution 1 is to preset the brazing material 1 in the socket of the pipe joint 2 by a press. When connecting the pipes, the connected pipe 3 is inserted into the socket of the pipe joint 2 that has been pre-prepared with the brazing material 1, and the part to be brazed is welded at high temperature, and the brazing material 1 is in a molten state, and the brazing is completed. Scheme 2 is that the brazing material 5 is preset in the socket of the pipe joint 4 through a die-casting machine. When connecting the pipes, the connected pipe 3 is inserted into the socket of the pipe joint 4 which has been pre-prepared with the brazing material 5, and the part to be brazed is welded at high temperature, and the brazing material 5 is in a molten state, and the brazing is completed.

[0009] Both the molding of the powdered brazing material and the die-casting molding belong to the known technology, which will not be repeated here.

Abstract

A pipe joint pre-soldered. In order to overcome the inconvenience of inhomogeneous melting of brazing material and adding brazing material in the brazing process, the present invention adopts the scheme of presetting brazing material at the socket position of the pipe joint, making it a pipe joint with pre-set brazing material . During the brazing process of the pipe connection, the socket part of the pipe joint 2 is heated by the flame, and the brazing material 1 preset at the socket position of the pipe joint 2 first melts and is evenly fused, and the connected pipe 3 and The connecting portion of the pipe joint 2 is uniformly contained by the brazing material. This not only avoids missing welding caused by uneven distribution of brazing material, but also frees up the operator to do other things, which not only improves the welding quality but also improves the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of pipeline brazing, and in particular relates to pipeline brazing connectors in heating, ventilation, refrigeration and thermal engineering. Background technique [0002] In traditional construction, brazing between pipes and between pipes and other pipe joints needs to add brazing material between the two. The operator holds the brazing material and adds the brazing material while heating it. Sometimes Because the limitation of the operating angle will also cause the brazing material to melt unevenly, resulting in missing soldering. Secondly, both hands are occupied in actual operation, which is very inconvenient especially when working at heights. The solution of the present invention is to solve these two problems , so that the brazing process of the pipeline is very convenient. Contents of the invention [0003] In order to overcome the inconvenience of inhomogeneous melting of brazing material and a...
