Flexible Telescopic Pipe Coupling Angular Deviation Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible telescopic pipe couplings fail to adequately compensate for angular deviations and changes in distance between connecting pipes, leading to excessive contact pressure on flange areas when fixing, especially under inclined conditions.
Innovation Solution
The use of spherical disks with convex sides, mounted in receiving holes, distributes fastening pressure evenly across flanges, allowing for adjustable and fixed angular positions without excessive stress, combined with a telescopic section for length compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixing elements are mounted directly in flanges without spherical disks, then the structure is simple, but excessive contact pressure is created on the flange areas when fixing at inclined positions
Solution Approach 1:
Spherical disks are introduced as intermediary elements between the fixing elements and the flanges. These disks have convex sides that engage with expansion millings in the flanges, allowing the fixing elements to be mounted at inclined positions while distributing the fastening pressure evenly across the flange surface, thus preventing excessive contact pressure at specific points
Solution Approach 2:
The spherical disks with convex sides provide a curved surface geometry that enables angular adjustment and inclination compensation. The spherical shape allows the fixing elements to be mounted at various angles while maintaining even pressure distribution through the convex engagement with the expansion millings in the flanges
2Device complexity
If the angular range for pipe coupling is limited, then the structure can be simpler, but a large number of different pipe elbows must be provided to cover all angular positions
Solution Approach 1:
The pipe coupling is designed with dynamic adjustment capabilities, allowing the angular position to be varied within a wide range (up to 360 degrees in some embodiments). The spherical disks and expansion millings enable the coupling to adapt to different angular positions while maintaining a secure connection, eliminating the need for multiple fixed-angle elbows
Solution Approach 2:
The pipe coupling design provides universal applicability across all angular positions by incorporating spherical disks that can engage with expansion millings at any orientation. This multi-functional capability allows a single coupling design to replace multiple specialized elbows, as it can accommodate any angular deviation between connecting pipes
3Productivity
If fixing elements are mounted at inclined positions without spherical disks, then the installation is faster, but the fastening pressure is not evenly distributed across the flanges
Solution Approach 1:
The spherical disks act as mediators that facilitate inclined mounting of fixing elements while ensuring even pressure distribution. The convex sides of the spherical disks engage with the expansion millings, allowing the fastening nuts to be screwed on without requiring precise alignment, thus maintaining both installation speed and pressure uniformity
