Embodiment 1

[0035] see Figure 4-8 As shown, an axial crimping joint includes a looper flange 1 and a flexible pipe body 10; the looper flange 1 is a flange structure, and the flexible pipe body 10 includes inner rubber in turn from the inside to the outside layer 2, skeleton layer 3, and outer rubber layer 4, the crimp joint is located at the end of the flexible pipe body 10,

[0036] The buckle joint also includes an outer pressure ring 5 and an inner pressure ring 6, the outer pressure ring 5 and the inner pressure ring 6 are annular sleeve structures, and the outer pressure ring 5 is sheathed on the end of the flexible pipe body 10. Outside the inner rubber layer 2, an annular boss 21 is provided outside the end of the inner rubber layer 2, and the inner ring end of the outer pressure ring 5 is provided with a corresponding annular depression 51, and the boss 21 is embedded The sealing structure between the joint and the conveying medium in the pipe is formed in the depression 51; th...

Abstract

The invention relates to an axial buckling and pressing connector. The axial buckling and pressing connector comprises an intra-pipe glue layer, a framework layer and an extra-pipe glue layer which are all of cylindrical structures and are sequentially connected in a sleeved manner from inside to outside to form a pipe body; the intra-pipe glue layer and the framework layer extend out of the pipe body from the same end, and the framework layer is made of flexible materials; the buckling and pressing connector further comprises an outer pressing ring and an inner pressing ring, the front end of the extending-out end of the intra-pipe glue layer is sleeved with the outer pressing ring, and the back section of the framework layer is sleeved with the inner pressing ring; and the outer pressing ring, the front section of the framework layer, the inner pressing ring and a piston flange are sequentially pressed in a butting manner from the extending-out end to the other end in the axial direction of the pipe body and are integrally molded through vulcanization. Compared with a flexible connecting pipe with the same length, a connecting structure adopting the connector and the pipe body is characterized in that the connector size is small, the flexibility section of the pipe body is long, the structure is simple, installation is flexible, and the connector and the pipe body are more firmly combined through vulcanization integrated molding. The technical problems that a traditional axial buckling and pressing connector is low in connecting strength, poor in pulling and dropping resistance and free of the self-locking function are solved.

Description

technical field [0001] The invention relates to an axial crimping joint, in particular to an axial crimping joint structure of a flexible joint. The utility model belongs to the technical field of pipeline connectors and is mainly used for pipeline systems of various working media such as oil and water. Background technique [0002] At present, in the petroleum, chemical, shipbuilding and other industrial fields, a large number of pipeline systems using oil, water, etc. as working media are laid. force, vibration and displacement. Therefore, a large number of rubber flexible joints are used in the pipeline system to play the role of vibration reduction and noise reduction, impact resistance, displacement compensation and transmission medium. When the pipeline diameter is large (above DN32), the flange joint is generally used to connect the metal pipeline and the rubber flexible joint. In order to ensure the safety and reliability of the pipeline system, the flange joint st...
