Abstract

The invention is a two-way crimping joint with fatigue resistance, impact resistance and pull-out resistance, comprising a crimping joint, a looper flange and a flexible pipe body; the crimping joint includes an outer pressure ring and an inner pressure ring; Structure, the flexible pipe body is provided with an inner rubber layer, a skeleton layer, at least two fatigue-resistant buffer layers, and an outer rubber layer in order from the inside to the outside at the connection between the crimping joint and the pipe body. The outer pressure ring is outside the fatigue-resistant buffer layer, and the outer pressure ring is turned out of the dovetail groove to enclose the annular disk of the inner pressure ring. 270°, the bidirectional crimping joint and the pipe body are integrally formed by vulcanization, the joint of the invention is firmly combined with the pipe body, and the fatigue-resistant buffer layer can effectively relieve and release the impact stress from the flexible pipe body to the rigid joint. The technical effects of high connection strength, strong pull-out resistance, and high fatigue and impact resistance are achieved.

Description

technical field [0001] The invention relates to a bidirectional crimping joint with fatigue resistance, impact resistance and pull-off resistance, in particular to a crimping joint structure of a flexible connecting pipe. 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 petroleum, chemical industry, hydraulic machinery, shipbuilding and other industrial fields, a large number of pipeline systems using oil and water as working media are widely used. Under the action of equipment operation, thermal expansion and contraction, vibration and shock, etc. Corresponding forces, vibrations, noises and displacements are produced. Therefore, a large number of rubber hoses are used in the pipeline system to play the role of vibration reduction and noise reduction, fatigue resistance and impact resistance, displacement compensation a...
