Abstract
The invention discloses a tube connector with preset brazing filler metal. To overcome the situation that brazing filler metal is not uniformly molten and the brazing filler metal is inconvenient to add in the brazing process, a scheme that the brazing filler metal is preset in a holding position of a tube connector, and thus the tube connector with the preset brazing filler metal is developed. In the brazing process for pipeline connection, the holding part of the tube connector 2 is heated with flame, the brazing filler metal 1 preset in the holding position of the tube connector 2 can be firstly molten and is uniformly welded, and the connecting part of a connected tube 3 and the tube connector 2 is uniformly coated by the brazing filler metal. By adopting the tube connector, both welding omission caused by non-uniform distribution of the brazing filler metal is avoided, and hands of an operator can be released to handle other things, so that both the welding quality and the production efficiency are improved.
Description
Technical field
The invention belongs to pipeline soldering tech field, be specifically related to the pipeline soldered joint in HVAC, refrigeration and thermal technology's engineering.
Background technology
In traditional construction, between pipeline and pipeline, soldering between pipeline and other pipe joints needs to add between cored solder, the hand-held cored solder of operator, while cored solder is added on limit of heating it, sometimes because the restriction of work angle also can cause cored solder to melt uneven thus produce solder skip, secondly, in practical operation, two hands are all occupied, especially very inconvenient during work high above the ground, the solution of the present invention is to solve the two problem, and the brazing process making pipeline is very convenient.
Content of the invention
In order to overcome owing to cored solder melts inconvenience that is uneven and that add cored solder in brazing process, present invention employs the scheme in the preset cored solder of pipe joint bellmouth part, make the pipe joint of preset cored solder, specific as follows:
Scheme of the present invention is: the 1st, powdery cored solder presets to meet the shape of pipe joint bellmouth by forcing press and mould；Then the bellmouth part being preset in pipe joint by forcing press, is characterized in that pipe joint has been prefixed cored solder, the 2nd, is to melt cored solder and be preset at pipe joint bellmouth part by die casting machine；It is characterized in that pipe joint has been prefixed cored solder, the pipe joint made by any of the above-described scheme has been prefixed cored solder, in implementing the brazing process that pipeline connects, bellmouth part is heated by flame, first melting less than the cored solder of pipe joint fusing point and by welding equably, the coupling part of two pipe joints is brazed material and uniformly contains.Do so had both avoided the solder skip causing due to cored solder skewness, makes again operator free hand to do other things, not only improves brazing filler metal quality but also improve production efficiency.
Brief description
Below by drawings and Examples, the present invention is further described.
In FIG, by forcing press, powdery cored solder is pressed into cored solder 1, is then preset in the bellmouth of pipe joint 2.When carrying out pipeline soldering, connected tube 3 inserts in the bellmouth of pipe joint 2.
In fig. 2, it is preset at the cored solder 5 melted in the bellmouth of pipe joint 4 by die casting machine.When carrying out pipeline soldering, connected tube 3 inserts pipe joint 4, bellmouth in.
Detailed description of the invention:
Scheme 1 is by forcing press, cored solder 1 to be preset in the bellmouth of pipe joint 2.When carrying out pipeline connection, connected tube 3 inserts in the bellmouth of the pipe joint 2 being prefixed cored solder 1, carries out high temperature welding to the part needing soldering, and cored solder 1 is in molten condition, completes soldering.Scheme 2 is that cored solder 5 is preset in the bellmouth of pipe joint 4 by die casting machine.When carrying out pipeline connection, connected tube 3 inserts in the bellmouth of the pipe joint 4 being prefixed cored solder 5, carries out high temperature welding to the part needing soldering, and cored solder 5 is in molten condition, completes soldering.
The shaping of powdery cored solder and die cast are belonged to known technology, does not repeats them here.
Claims (1)
1. a pipe joint for preset cored solder, including pipe joint and cored solder, is characterized in that being prefixed cored solder on pipe joint.
