Low-rigidity anti-impact large-displacement compensation balance type double-arc-shaped flexible connecting pipe

Abstract

The invention discloses a low-rigidity anti-impact large-displacement compensation balance type double-arc-shaped flexible connecting pipe. The low-rigidity anti-impact large-displacement compensationbalance type double-arc-shaped flexible connecting pipe comprises a flexible pipe body and a buckling connector, the buckling connector comprises an outer pressing ring, an inner pressing ring and aloose flange, and the flexible pipe body is composed of straight pipe sections with the buckling connector arranged at the two ends and a double-arc-shaped pipe body between the straight pipe sections; the double-arc-shaped pipe body is formed by connecting a transition connecting section pipe body in the middle with single arc-shaped pipe body which are symmetrically arranged at the two ends of the double-arc-shaped pipe body and arch outwards in the radial direction, the flexible pipe body sequentially comprises an inner rubber layer, a framework layer and an outer rubber layer from inside to outside, and a fatigue-resistant buffer section, a low-rigidity compensation section, an impact-resistant enhancement section and a fatigue-resistant balance constraint section are symmetrically arranged in the middle; and the outer pressing ring and the inner pressing ring clamp the overturned and reversely-wrapped framework layer and then are integrally formed with the flexible pipe body through vulcanization, and a loop flange is arranged outside the inner pressing ring. In a pipeline system with the drift diameter DN125 or above, and the technical effects of compressive strength, vibration and noise reduction, low rigidity, impact resistance, fatigue resistance, pull-out resistance, large displacement compensation, balance, stability and reliability can be achieved at the same time.

Description

technical field [0001] The invention relates to a low-rigidity and anti-impact large-displacement compensation balanced double-arc 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] In various industrial fields such as petroleum, chemical industry, hydraulic machinery, shipbuilding, etc., a large number of pipeline systems using oil, water, etc. as working media are widely used. , will produce corresponding force, vibration, noise and displacement. Therefore, a large number of rubber hoses are used in the pipeline system to play the role of vibration reduction and noise reduction, displacement compensation, impact resistance, fatigue resistance and transmission medium. In the design and use of flexible joints, it is necessary to consider the compressive strength of the pipe body, fatigue resistance, rigidity of...
