Compressible Rupture Disk Flange for Leak-Tight Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of rupture disks often results in damage to the membrane due to the lack of a secure sealing mechanism, and existing methods using lubricants are not always effective in preventing leakage and ensuring a tight seal.
Innovation Solution
A rupture disk design featuring a compressible flange with perimetrically extending voids that expand radially upon axial compression, allowing for a tight seal without the need for lubricants, and can be easily inserted into a housing with minimal risk of damage, utilizing a compression mechanism to secure the disk in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rupture disk is installed in a housing to prevent fluid leakage, then sealing performance is improved, but the risk of damaging the membrane during installation increases
Solution Approach 1:
The flange is segmented with radially extending voids that allow the material to compress and expand in a controlled manner during installation, enabling the flange to deform into a sealing position without exerting excessive force on the membrane
Solution Approach 2:
The flange material undergoes parameter changes through compression, transitioning from a larger diameter state during installation to a compressed state that forms the seal, with the voids enabling this transformation without damaging the membrane
2Ease of operation
If the rupture disk diameter is reduced for easier handling, then ease of operation is improved, but sealing effectiveness may be compromised
Solution Approach 1:
The flange is designed to be dynamic in size, allowing the rupture disk to have a larger diameter for easy handling during installation, then compressing to a smaller diameter to form an effective seal once in position
Solution Approach 2:
The sealing mechanism operates in the radial dimension through flange compression, allowing the disk to be inserted easily in one dimension while achieving sealing in another dimension through material deformation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enables a secure, leak-proof installation of rupture disks, facilitating quick and damage-free insertion, and ensures effective pressure relief by forming a tight seal between the disk and the housing, even in high-pressure applications.
Implementation Method 1
The flange of the rupture disk may be compressed in use, allowing significant expansion of the flange to be achieved parallel to the disk when the flange is compressed perpendicularly to the disk
Implementation Method 2
the provision of such a void within the flange of the rupture disk allows significant expansion of the flange to be achieved parallel to the disk when the flange is compressed perpendicularly to the disk
