Metal Sealing Disk With Elastomeric Backing For Fluid Regulators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid regulators face challenges with elastomeric sealing disks that wear quickly in severe service conditions and metal sealing disks that fail to provide a reliable seal due to perpendicularity issues, leading to leakage and contamination.
Innovation Solution
A metal sealing disk with an elastomeric backing that allows the metallic ring to shift and self-align with the valve seat, minimizing misalignment and ensuring a robust, durable seal in harsh conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an elastomeric sealing disk is used, then flexibility and resilience are improved, but wear resistance and durability deteriorate in severe service conditions
Solution Approach 1:
The sealing disk is constructed as a composite structure with a metal substrate providing wear resistance and durability, combined with an elastomeric coating layer providing flexibility and sealing capability. This composite construction allows the disk to withstand severe service conditions while maintaining operational flexibility and sealing effectiveness.
2Reliability
If an elastomeric sealing disk is used, then sealing capability is improved, but susceptibility to erosion and damage increases in severe service conditions
Solution Approach 1:
The composite structure protects the elastomeric sealing layer by providing a durable metal substrate that resists erosion from high-velocity fluids and particulate matter. The metal substrate acts as a protective barrier, allowing the elastomeric coating to maintain its sealing capability without being directly exposed to erosive conditions.
