Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline side joint. Background Art

[0002] In current piping systems, pipes are mostly made of PVC, aluminum-plastic composites, and plastic materials. During construction, as the main pipeline is laid, it is often necessary to branch out branches using tees or crosses. The layout of these branches requires pre-designed design, with the main pipeline cut off and connected to the tees or crosses. Furthermore, installing these tees and crosses increases the number of pipe connections, increasing the risk of leaks.

[0003] Furthermore, these connectors are only suitable for use on the end faces of tubular components. After pipeline installation, some pipelines may need to be temporarily branched. This requires drilling a hole in the circumference of the main pipe to directly connect a branch pipe. Currently, most side pipe connections are made using hot-melt technology, where a connector is secured to the pipe opening via welding or hot-melt. Over time, these welded or hot-melt connections are prone to water seepage, loosening, or even being directly washed away by water pressure, resulting in a short service life. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a pipeline side joint, which can be used to connect a branch pipe to the main pipeline, is easy to operate and is not prone to water leakage.

[0005] To this end, the technical solution of the present invention is: a pipe side joint, comprising a tubular body, a connecting surface with a curved structure at one end of the tubular body, and a pipe interface at the other end; a protruding connecting column is provided in the middle of the connecting surface, and a mounting groove is also provided on the connecting surface around the outside of the connecting column; a sealing sleeve is provided on the outside of the connecting column, and a first sealing surface and a second sealing surface are provided at both ends of the sealing sleeve, the first sealing surface is placed in the mounting groove, and the second sealing surface is flush with the connecting column.

[0006] On the basis of the above solution and as a preferred solution of the above solution: the radial cross-section of the sealing sleeve is an I-shaped structure, and the first sealing surface and the second sealing surface are both curved structures.

[0007] On the basis of the above solution and as a preferred solution of the above solution: the sealing sleeve is made of rubber.

[0008] On the basis of the above solution and as a preferred solution of the above solution: the height difference between the first sealing surface and the second sealing surface is consistent with the thickness of the pipe wall at the pipe opening.

[0009] On the basis of the above solution and as a preferred solution of the above solution: the pipeline interface is provided with an external thread structure or an internal thread structure.

[0010] During use, a hole is drilled on the pipe, and the size of the hole is adapted to the outer diameter of the connecting column on the joint; after drilling the hole, the connecting column and the sealing sleeve are inserted into the hole. Since the sealing sleeve is made of rubber, the second sealing surface can be bent and inserted into the hole. The connecting column and the hole are tightly fitted through the sealing sleeve. The first sealing surface and the second sealing surface of the sealing sleeve are just clamped on the wall of the pipe hole, which plays a further sealing role; the connecting surface of the curved structure is fitted with the outer surface of the pipe and fixed by hot melting.

[0011] Compared with the prior art, the beneficial effects of the present invention are: a connecting column is provided on the connecting surface of the side joint, and an I-shaped sealing sleeve is sleeved on the outside of the connecting column, and the sealing sleeve is used to improve the sealing between the joint and the pipe hole, reduce the risk of water leakage, and extend the service life of the pipe.
