Contoured Support Ring Arrangement for High-Pressure Seals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-pressure seals in containers face challenges with maintaining sealing integrity under extreme pressures up to 10,000 bar, as they are prone to deformation and leakage due to compressive and tensile stresses, and the container's expansion or contraction creates gaps that allow the seal to creep or flow.
Innovation Solution
A support ring arrangement with contoured molded parts featuring parallel, conical mating surfaces that abut each other, providing axial fixation and preventing gaps, and can be made from high-strength alloys like copper, titanium, or steel, with a clamping device to secure the assembly under pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high-pressure seal is used to seal the cylindrical part of the high-pressure container, then sealing effectiveness is improved, but the seal is prone to deformation and leakage under extreme pressures up to 10,000 bar
Solution Approach 1:
The support ring arrangement is divided into multiple contoured molded parts (at least two) that are mutually supporting. This segmentation allows each part to bear specific portions of the radial load, distributing the stress and preventing deformation of the high-pressure seal under extreme pressures up to 10,000 bar.
Solution Approach 2:
The support ring arrangement uses contoured molded parts made from high-strength alloys such as copper, titanium, or steel. These composite material structures provide the necessary strength and rigidity to maintain sealing integrity under extreme pressure conditions while resisting deformation.
2Stress or pressure
If the container and container closure expand or compress under high pressure, then the container can withstand the pressure, but gaps or crevices form that allow the seal to creep or flow
Solution Approach 1:
The support ring arrangement features contoured molded parts with parallel, conical mating surfaces that allow for dynamic adjustment. As the container and closure expand or compress under pressure, the support rings can shift and adjust their position while maintaining contact through the conical surfaces, preventing gaps and crevices that would allow seal creep.
Solution Approach 2:
The parallel, conical mating surfaces of the support rings are designed with specific geometric parameters (cone angle, surface orientation) that enable the structure to adapt to dimensional changes in the container and closure. This parameter optimization ensures structural stability is maintained even as the container volume changes under extreme pressure.
3Reliability
If multiple support elements are added to prevent gaps and support the seal, then sealing reliability is improved, but device complexity increases
Solution Approach 1:
The support ring arrangement combines multiple contoured molded parts into a single integrated assembly that works together to support the high-pressure seal. The parts are mutually supporting with parallel, conical mating surfaces that allow them to function as a unified structure, providing reliable seal support without excessive complexity.
Solution Approach 2:
The contoured molded parts of the support ring arrangement serve multiple functions simultaneously: they provide structural support, prevent gap formation, distribute radial loads, and accommodate dimensional changes in the container. This multi-functionality reduces the need for additional separate components, maintaining simplicity while ensuring sealing reliability.
