Description

Technical Field

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

[0002] Pipeline connection refers to connecting prefabricated pipe sections into a complete system according to the requirements of the design drawings. During construction, different connection methods should be selected according to the material of the pipe used. The connection methods of ordinary steel pipes include threaded connection, flange connection, welding connection, socket connection, pipe bonding connection, etc. The selection of these methods is based on the material of the pipe, the use environment and the specific needs of the connection.

[0003] When connecting existing large-diameter pipes that have been cut or are not provided with connecting structures such as docking flanges, they can generally only be connected by welding or bonding. When welding or bonding, auxiliary tools such as docking devices are required for auxiliary operations. During the connection process, welding or bonding operations are also required, which makes the connection of large-diameter pipes very inconvenient and inefficient, affecting the progress of pipeline laying. Therefore, a pipe connecting device is proposed. Utility Model Content

[0010] Furthermore, the two movable rings both include a threaded ring, and the threaded ring is threadedly sleeved on the outer surface of the annular seat, a shielding ring is fixedly connected to one side of the outer surface of the threaded ring, and the auxiliary rod is threadedly connected to the shielding ring, and the shielding ring has a shielding effect to prevent the installation groove from being exposed.

[0011] Furthermore, the two pushing components both include a rotating ring, and the rotating ring is rotatably embedded in the inner wall of the shielding ring. The inner surface of the rotating ring is fixedly connected with a plurality of inclined push blocks, and the inclined push blocks are slidingly connected to adjacent mounting grooves and fit with the inclined surfaces of adjacent inclined pressure blocks. The mounting grooves have a limiting effect on the movement of the inclined push blocks, thereby ensuring the stability of their movement.

[0012] Furthermore, a conical groove is provided at the entrance of the two annular butt joint grooves to increase the entrance diameter of the annular butt joint grooves and facilitate the insertion of the pipeline into the annular butt joint grooves.

[0013] Furthermore, a plurality of sealing rings are fixedly connected to the inner walls of one side of the two annular butt joint grooves, and the sealing rings abut against the inner walls of the adjacent pipes, thereby ensuring the sealing of the connection between the annular butt joint grooves and the pipes.
