Quick pipeline connecting flange

Abstract

The invention relates to a quick pipeline connecting flange comprising a flange body. The flange body is cylindrical, and the outer edge of the front end is provided with screw holes and bolts being in butt joint with and fixed to a butt flange. The quick pipeline connecting flange is characterized by being further provided with a clamping component group clamping the flange body to the outer wall of a connected pipeline and a sealing component group sealing the flange body and the outer wall of the pipeline; the clamping component group is arranged on the inner wall of the outer end of the flange body, the sealing component group is arranged on the inner wall of the inner end of the flange body, and the outer periphery of the clamping component group is attached into the groove of the inner wall of the outer end of the flange body; the outer periphery of the sealing component group is fixed to the inner wall of the inner end of the flange body and connected and fixed to the flange body through the bolts at the rear end. The clamping component unit is provided with a slip and a slip sleeve; the sealing component group is provided with a locking ring, a rubber ring and a butting flange sequentially from outside to inside. The quick pipeline connecting flange is applicable to pipelines, in particular to maintenance of underwater submarine pipelines, and has the advantages of high working efficiency, reliable sealability and firmness, high adaptability, maintenance cost saving and the like.

Description

technical field [0001] The invention relates to a mechanical manufacturing technology, in particular to a quick connection flange for pipeline connection, which is suitable for the connection of various pipelines, especially for the quick connection of pipelines in operation, underwater and seabed pipelines. Background technique [0002] In marine engineering, the emergency repair of pipelines has always been a worldwide engineering problem. Because of the complex and changeable seabed environmental factors, the maintenance of pipelines becomes very difficult. In particular, the connection engineering of pipelines is particularly difficult. In order to solve the connection problem of the pipeline, it is often necessary to weld the flange at the end of the pipeline. The welding of the connecting flanges of underwater pipelines is a very big problem. It is often necessary to stop the production and operation of pipelines in a large area, and it is very difficult to move the ...

AI Technical Summary

Problems solved by technology

The welding of the connecting flanges of underwater pipelines is a very big problem. It is often necessary to stop the production and operation of the pipelines in a large area, and it is very difficult to move the pipelines and set up the welding environment.

The construction period is long and the investment is large, which brings great losses to production and the environment

There have been some maintenance and connection technologies and devices for underwater pipelines, but most of them are not very satisfactory in performance, and further improvement and improvement are urgently needed.
