Quick butt-joint bend unit for conduit

Abstract

The invention discloses a quick butt-joint bend unit for a conduit. A socket female port is arranged at at least one port of the bend unit, wherein the internal diameter of the socket female port matches an external diameter of a conduit; and a flange is arranged at the inner wall of the pipe cavity of the socket female port. A mark is arranged at the quick butt-joint bend unit and is used for marking a radius value of a corner of the bend unit; and a mark is also arranged at the butt-joint bend unit and is used for marking a caliber value of the bend unit. According to the bend unit in mechanical moulding, because of the socket female port, the pipe can be extended when a straight pipe is inserted into the port, so that the operation becomes convenient and rapid. The radius value of the corner of the bend unit is marked, so that the location sequence of the bend unit can be identified based on the radius value. The bend unit and the straight pipe are connected in a socket mode and a chamber is arranged for transition, quick butt joint is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of threading pipes for decoration, in particular to a quick butt joint elbow of threading pipes. 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 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; During the process, the pipe may be cracked or broken, resulting in failure of the bend. This operation method is labor-intensive and time-consuming, and the size of the hand-made elbows is ever-changing, and there are traces of stretching at the bending parts, which affects the appearance of the overall layout. Contents of the invention [0003] In order to solve the abo...
