Line pipe butt joint elbow

Abstract

The invention discloses a line pipe butt joint elbow. The pipe diameters of the two ports of the elbow are different. At least one port of the elbow is provided with a socket female interface. The inner diameter of the socket female interface is the same as The outer diameter of the line pipe is adapted, and the inner wall of the cavity of the socket female interface is provided with a flange. Marks are respectively provided at the two ports of the butt elbow to mark the pipe diameter values ​​at the two ports of the elbow; marks are provided on the butt elbow to mark the radius value of the corner of the elbow. The two ports of the invention can adapt to the butt joint of straight pipes with different pipe diameters, and the mechanically formed elbow has its own socket female interface. The straight pipe can be inserted to extend the pipeline, which is convenient and quick. The butt elbow is provided with marks for identifying the pipe diameter at the two ports of the elbow and the radius value of the corner of the elbow. Easy to identify and easy to connect with straight conduit.

Description

technical field [0001] The invention belongs to the technical field of decoration wire pipes, in particular to a wire pipe butt joint elbow. Background technique [0002] At present, the pipe elbow joints on the construction site are all handmade and bent. After bending and forming, then use a straight-through to connect with the pipe, figure 1 It is a schematic diagram of the structure of the 90-degree elbow in the prior art. The steps are: first measure the size, then cut the pipe and cut the material, and start bending with the pipe bender. After bending, the size is wrong and continue to adjust; During the process, the pipe may be cracked or broken, resulting in failure of the bend. This method of operation is labor-intensive and time-consuming, and the size of the hand-made elbows is ever-changing, and there are stretch marks in the bending parts, which affects the appearance of the overall layout. [0003] The pipe diameters at both ends of the existing butt joint e...

After bending and forming, then use a straight-through to connect with the pipe, figure 1 It is a schematic diagram of the structure of a 90-degree elbow in the prior art. The steps are: first measure the size, then cut the pipe, and start bending with the pipe bender. After bending, the size is wrong and continue to adjust; The pipe may be cracked or broken during the process, resulting in failure of the bend

This method of operation is labor-intensive and time-consuming, and the size of the hand-made elbows is ever-changing, and there are stretch marks on the bending parts, which affects the appearance of the overall layout

[0003] The pipe diameters at both ends of the existing butt joint elbow are the same, and it cannot adapt to the case where the diameters of the line pipes at the two ports are different.
