Multi-Surface Coupling Gasket for Pressure-Resistant Pipe Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe coupling technologies face challenges in providing a reliable and efficient sealing mechanism for joining pipe elements, particularly due to issues with gasket deformation and fluid pressure, which can lead to leakage and damage from fluid buildup.
Innovation Solution
A pipe coupling system featuring a gasket with annular body and radially inwardly extending sealing ribs, designed to compress and deform uniformly around pipe elements, providing a cylindrical sealing surface that adapts to the pipe diameter and enhances sealing efficacy by utilizing fluid pressure for a more effective seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional single-sealing-surface gasket is used, then the structure is simple, but the sealing reliability is insufficient under fluid pressure
Solution Approach 1:
The gasket is divided into multiple sealing surfaces (first sealing surface on the first gasket face, second sealing surface on the second gasket face) instead of using a single sealing surface. This segmentation allows the sealing function to be distributed across multiple contact points with the pipe, improving overall sealing reliability while maintaining a relatively simple overall structure.
2Reliability
If the gasket is tightly compressed to prevent leakage, then sealing effectiveness improves, but fluid buildup and damage risk increase
Solution Approach 1:
By providing multiple sealing surfaces, the gasket creates multiple narrow sealing zones rather than one large compressed area. This allows fluid pressure to be distributed across multiple smaller contact points, maintaining sealing effectiveness while reducing the risk of fluid buildup and associated damage.
Solution Approach 2:
Different regions of the gasket (first gasket face vs. second gasket face) provide sealing functions with potentially different characteristics. The local sealing properties can be optimized for specific pressure conditions, allowing effective sealing without excessive compression that would cause fluid buildup.
3Adaptability or versatility
If the gasket diameter is reduced to fit smaller pipes, then adaptability improves, but sealing surface area decreases
Solution Approach 1:
The sealing function is segmented across two separate gasket faces, each providing its own sealing surface. This allows the gasket to maintain adequate total sealing surface area even when the overall gasket diameter is reduced for smaller pipe adaptability.

AI summary
A coupling sized for use with a pipe having a pipe outer diameter, the coupling including a pair of segments; and a gasket positioned between the pair of segments, the gasket including an annular body; and a pair of sealing ribs each extending substantially radially inwardly from the annular body, each sealing rib of the pair of sealing ribs defining a cylindrical sealing surface at an innermost radial extent in an uncompressed state, the cylindrical sealing surfaces each defining an inner gasket diameter that is larger than the pipe outer diameter when the gasket is in the uncompressed state.
