Description

Bulb and pipeline welding

Technical Field

The utility model belongs to the technical field of bulb and pipeline are brazed, especially relate to the brazing of metal pipeline.

Background

With the rapid development of the industry in China, the application of pipeline brazing in the industry is wider and wider, but the brazing of the pipeline always has the problems of complex processing of a butt joint part or insufficient welding strength.

As in the manner of patent 201110361784.7, the joint portions are beveled at complex machining and the weld thickness is not uniform. As in the mode of patent 201220518999.5, two pipelines are connected by interference fit, the solder can only form a weld joint at the end face and the small annular extension part, the welding length is small, and the welding strength is insufficient, while in the mode of patent 201420762390.1, the protruding edge of the pipe orifice has poor stability during molding, the rejection rate is high, and the precision requirement on a molding die is high.

SUMMERY OF THE UTILITY MODEL

For solving the technical problem, the utility model provides a processing is simple, and stability is good, and the full rate of welding seam is high, and welding length is big, bulb and the pipeline welding that welding strength is big.

The utility model discloses a bulb and pipeline welding, including pipeline, solder and bulb, the body of pipeline is the tubulose, and the top of bulb is provided with the bulb hole communicating pipe, and the bottom of pipeline passes through the bulb top and inserts in the bulb hole, and the bottom of pipeline contacts with the bottom of bulb hole, and the solder is filled between pipeline outer wall and bulb hole inner wall; the welding material is filled on the inner wall of the ball head hole in the ball head, the bottom end of the pipeline is inserted into the ball head hole, the pipeline, the welding material and the ball head are placed into a brazing furnace after installation or directly heated to melt the welding material to complete welding, the welding mode of the pipeline, the welding material and the ball head is adopted, the processing cost is low, the operation is convenient, all the ball heads can be suitable for being connected with the pipe fittings, the welding seam thickness is uniform and even, the welding plumpness is high, the welding length is large, and the welding strength can be greatly improved.

The utility model discloses a bulb and pipeline welding, the inner wall of bulb hole evenly is provided with the multiunit bump, the inner of multiunit bump evenly the outer wall interference contact of pipeline; when the bottom of pipeline was inserted in the inside in bulb hole, the mode that can adopt external withhold equipment to carry out the suppression pressed the pipeline downwards, and the outer wall of pipeline is connected with the downthehole multiunit bump interference of bulb, through setting up the multiunit bump, can effectively improve the fastness that pipeline and bulb are connected, improves welding quality.

The utility model discloses a bulb and pipeline welding, the welding flux can use different forms of welding flux such as welding ring, welding mud, etc. when selecting materials; due to the diversity of the selected materials of the welding flux, the welding mode can be effectively simplified, and the welding applicability is improved.

The utility model discloses a bulb and pipeline welding, the inner diameter of the bulb hole can be adjusted according to the actual raw material and the process requirement; by adjusting the inner diameter of the ball head hole, the gap between the inner wall of the ball head hole and the outer wall of the pipeline can reach the optimal value conveniently, and the welding strength is improved conveniently.

The utility model discloses a bulb and pipeline welding, the height of multiunit bump can be adjusted according to actual raw materials and technological requirements; through the height of adjustment multiunit bump, can conveniently adjust the magnitude of interference between multiunit bump inner and the pipeline outer wall to conveniently make the magnitude of interference reach the optimal value, improve the practicality.

Compared with the prior art, the beneficial effects of the utility model are that: the welding material is filled on the inner wall of the ball head hole in the ball head, the bottom end of the pipeline is inserted into the ball head hole, the pipeline, the welding material and the ball head are placed into a brazing furnace after installation or directly heated to melt the welding material to complete welding, the welding mode of the pipeline, the welding material and the ball head is adopted, the processing cost is low, the operation is convenient, all the ball heads can be suitable for being connected with the pipe fittings, the welding seam thickness is uniform and even, the welding plumpness is high, the welding length is large, and the welding strength can be greatly improved.
