A flexible pipeline connection device

Abstract

This utility model discloses a pipeline protection technology, specifically a flexible pipeline connection device, including an arc-shaped frame. Four sets of arc-shaped frames are arranged in pairs facing each other, forming a chamber between the pairs of opposing arc-shaped frames to accommodate the pipeline. A base plate is integrally formed on the outer side of the arc-shaped frame. Multiple buffer components are arranged between the pairs of opposing arc-shaped frames to protect the connected pipelines. The four sets of arc-shaped frames, arranged in pairs facing each other and connected to the buffer components via the outer base plate, form a stable frame structure. This ensures secure installation and evenly distributes loads from all directions, improving the entire connection device's resistance to bending, torsion, and lateral impact, and ensuring the stability of pipeline alignment.

Description

Technical Field

[0001] This utility model relates to the field of pipeline protection technology, specifically a flexible pipeline connection device. Background Technology

[0002] In industrial fluid transportation, construction engineering, and machinery equipment, pipeline connections are an essential component. Traditional pipeline connections mostly employ rigid methods such as flanges and threads. However, these rigid connections lack the necessary compensation capacity when faced with foundation settlement, equipment vibration, thermal expansion and contraction, or external impacts. This can easily lead to significant stress concentration at the connection points, causing pipeline joints to loosen, welds to crack, or even the pipeline itself to be damaged, resulting in media leakage. This not only affects the normal operation of the system but also poses serious safety hazards.

[0003] To address the aforementioned issues, existing technologies have developed flexible connectors such as rubber expansion joints and metal bellows. While these components offer some compensation, they also have significant limitations. For instance, rubber expansion joints have poor pressure resistance, temperature resistance, and corrosion resistance, are prone to aging, and have a limited service life. Metal bellows, on the other hand, require precise installation alignment and have weak bending and lateral load resistance, making them susceptible to instability or fatigue damage under complex operating conditions. Therefore, there is an urgent need for a flexible pipeline connection device. Utility Model Content

[0009] In a preferred embodiment of the flexible pipeline connection device described in this utility model, a spring is fitted on the buffer, and the two ends of the spring are respectively arranged corresponding to the two ends of the substrate.

[0010] As a preferred embodiment of the flexible pipeline connection device described in this utility model, a corrugated pipe is connected inside the arc-shaped frame, and rubber pads are glued to both ends of the inner side of the corrugated pipe, with anti-slip grooves provided on the rubber pads.
