Description

Technical Field

[0001] The utility model relates to the technical field of municipal construction, in particular to a pipeline connection and positioning mechanism for relocating a tap water pipeline. Background Art

[0002] Water pipeline relocation refers to the relocation and installation of existing water pipelines to meet user needs or adapt to new land use requirements, ensuring the safety and stability of new land use while protecting the normal operation of the original infrastructure;

[0003] When relocating existing water pipelines, the direction of the pipeline network needs to be changed. The old pipeline network needs to be connected to the new pipeline network multiple times with connecting pipes, which makes the pipeline connection more inconvenient and affects the efficiency of the water pipeline relocation.

[0004] Due to the relocation of the original water pipes, the original water pipes will be corroded or aged after long-term use. After being connected to the new pipes, the connection strength is poor, and the connection is directly exposed to the outside, and its sealing cannot be guaranteed;

[0005] Therefore, the present application provides a pipe connection and positioning mechanism for relocating a water pipeline to meet the needs. Utility Model Content

[0006] The purpose of the present utility model is to solve the problems existing in the above-mentioned background technology, and to propose a pipeline connection and positioning mechanism for relocating a tap water pipeline.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A pipe connection and positioning mechanism for relocating a tap water pipeline comprises: an outer protective tube, a connecting inner tube, a tap, a pipe plug cover, a limiting ring, a supporting seat, a threaded column and a nut; the connecting inner tube is installed inside the outer protective tube, one end of the connecting inner tube is provided with a docking port, the other end of the connecting inner tube is provided with a receiving port, a tap is integrally provided on the side of the connecting inner tube, a pipe plug cover is installed on the outer end of the tap, a limiting ring is installed on the outer end of the outer protective tube, a supporting seat is integrally provided on the outer end of the limiting ring, a limiting hole is provided on the surface of the limiting ring, a threaded column is installed in the limiting hole, and a nut is installed on the outer end of the threaded column.

[0009] Preferably, the diameter of the outer protective tube is larger than the diameter of the connecting inner tube, and the connecting inner tube passes through the outer protective tube and extends outward to the outer end of the outer protective tube.

[0010] Preferably, the side surface of the connecting inner tube is integrally provided with two sets of joints, and the two sets of joints are mirror-symmetrically located at the left and right ends of the side surface of the connecting inner tube.

[0011] Preferably, the tap is close to one end of the receiving port, and the tap is located at the outer end of the outer protective tube.

[0012] Preferably, the diameter of the tap is smaller than the diameter of the connecting inner pipe.

[0013] Preferably, the limiting ring is nested at the outer end of the outer protective tube, and the surface of the limiting hole is provided with a threaded surface, and the threaded column and the limiting ring are threadedly connected.

[0014] Preferably, the threaded column extends inwardly along the limiting hole to the interior of the outer protective tube, and the other end of the threaded column abuts against the outer end of the connecting inner tube.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] 1. The butt joint of the inner pipe can be connected to the old water pipe by hot melting, and the socket joint can be connected to the new water pipe. The two sets of joints and the socket joint form a tee, which can facilitate the connection of pipes in all directions of the new pipeline when relocating the line, making the relocation of the water pipeline more convenient;

[0017] 2. After the inner connecting pipe is hot-melt connected to the old water pipe, insert the connecting point between the inner connecting pipe and the old water pipe into the outer protective pipe. By adjusting the insertion length of the threaded column, press the threaded column against the inner connecting pipe and tighten the nut to fix the connecting end of the old water pipe inside the inner connecting pipe. This not only protects the ports of old pipes of different diameters, but also improves the connection strength and sealing of the relocated pipes. BRIEF DESCRIPTION OF THE DRAWINGS
