Abstract

The invention provides a self-adaptive double-sealing-steel-ball clamping underwater pipeline connector. A spherical base body has three rotation freedom degrees relative to an outer cavity of the base body. When two pipelines with axes not coinciding with each other are connected, the relative positions of the spherical base body and the outer cavity of the base body are adjusted, so that the first pipeline and the second pipeline are smoothly placed into a first spherical cage and a second spherical cage, the tail ends of the pipelines reach pipeline thrust surfaces, nuts on a double-end stud are fastened, a flange ring and the outer cavity of the base body are tightly pressed on the spherical face of the spherical base body through axial force, and the relative positions of the spherical base body and the outer cavity of the base body are fixed; meanwhile, a metal sealing ring is tightly pressed on the spherical face of the spherical base body through axial force, so that reliable sealing operation between the spherical base body and the outer cavity of the base body is achieved. The two pipelines with an axis angle ranging from -10 degrees to 10 degrees can be connected through the self-adaptive double-sealing-steel-ball clamping underwater pipeline connector.

Description

technical field [0001] The invention relates to a pipeline connector, in particular to an underwater pipeline connector. Background technique [0002] For the repair and connection methods of submarine pipelines, there are mainly: underwater dry warehouse welding, bolt flange connection, clamp connection, etc. The connection process of these methods is complicated to operate and requires high relative position of the connected pipeline. Fast connections cannot be achieved, and the probability of failure is high, preventing efficient and reliable connections of pipes. Contents of the invention [0003] The purpose of the present invention is to provide an adaptive double-sealed steel ball clamping underwater pipeline connector suitable for the connection of two underwater pipelines. [0004] The purpose of the present invention is achieved like this: [0005] The self-adaptive double-sealed steel ball clamping underwater pipeline connector of the present invention is char...
