A kind of fire pipe fitting and its installation method

Abstract

The application relates to a fire-fighting pipe fitting and its installation method, which includes several pipe monomers, the outer peripheral surface of one end of the pipe monomer is fixed with a first annular protrusion, and the outer peripheral surface of the other end is fixed with a second annular protrusion. The outer diameter of the first annular protrusion is greater than the outer diameter of the second annular protrusion; in the adjacent pipeline monomers, the first annular protrusion of one of the pipeline monomers is connected to the other pipeline monomer The second annular protrusion of the body is abutted against; the first annular protrusion is provided with several screws, and several of the screws are circumferentially distributed on the outer peripheral side of the pipeline unit; several of the screws run through in a direction parallel to the axis of the pipeline unit The first annular protrusion abuts against the outer peripheral side of the second annular protrusion of another pipe unit; several of the screws are threaded with threaded fasteners, and the threaded fasteners and the screw are used for locking The first annular protrusion and the second annular protrusion between adjacent pipe monomers. This application has the effect of reducing the work intensity of installers.

Description

technical field [0001] The application relates to the field of installation of fire-fighting facilities, in particular to a fire-fighting pipe fitting and an installation method thereof. Background technique [0002] Fire-fighting pipe fittings refer to the pipe materials used for fire-fighting, connecting fire-fighting equipment and equipment, transporting fire-fighting water, gas or other media, and are particularly important components in fire-fighting facilities. [0003] In the related technology, the extension and lengthening of the fire-fighting pipeline is realized by connecting several fire-fighting pipe fittings in sequence. Generally, the ends of the fire-fighting pipe fittings are equipped with flanges, and the flanges are prefabricated with several mounting holes. The fixing between adjacent pipe fittings The flange plates abutted against each other are fixed by bolts, and are fixed on the frame body of the floor slab through threaded connection.

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the connection of adjacent fire-fighting pipes needs to be aligned with the mounting holes of the adjacent flanges, and the bolts are locked one by one, and the process of aligning the mounting holes needs to pass Rotating the fire pipe fittings makes the installers work hard, so there is still room for improvement
