Abstract

The invention relates to a pipeline connector. The pipeline connector is characterized in that a tubular connection body (3) is arranged, the front end of the tubular connection body is provided with a flange connection tray (2) while the rear end is provided with a flange pressure plate (6), the inner chamber of the connection body is internally provided with a sealing element that and a clasping element, wherein the sealing element consists of sealing rings (11.1, 11.2) and sealing ring retainer rings (12, 12.1, 12.2) arranged in parallel or at intervals, and the clasping element consists of a tubular slip (9) and a slip sleeve (8), the slip sleeve is sheathed outside the slip, the outer wall of the slip and the inner wall of the slip sleeve are respectively provided with chucking teeth(9.1, 8.1) matched with each other, the rear end of the slip sleeve is tightly pressed by the flange pressure plate, and the flange pressure plate and the rear end of the connection body are fixed byan axial bolt (7). The invention has advantages of simple and smart structure, quick and convenient operation and good leakage-proof effect; and particularly, by adopting the invention, broken pipelines can be removed flexibly, available pipelines can be reserved to the largest extent, the restoration work is simple and convenient, the materials can be saved, and the restoration cost can be reduced greatly.

Description

Technical field [0001] The invention belongs to a pipeline repairing technology, in particular to a repairing technology for underwater pipelines, especially subsea pipelines, and is a pipeline connector used to quickly connect a truncated pipe and a joint pipe in a repair operation. Background technique [0002] With the development of economy, more and more pipelines are laid underwater and under the sea. Due to the poor, even harsh, underwater and seabed environment, it has caused great difficulties for pipeline repair. Therefore, how to repair underwater and submarine pipelines quickly and with quality and quantity is an increasingly important issue. For this reason, it is necessary to provide a pipeline connecting device for rapid repair of underwater pipelines. Summary of the invention [0003] The purpose of the present invention is to solve the above technical problems and propose a pipeline connector, which has a simple structure, is very convenient to use, can quickly ...
