Test Port Assembly for Sealed Annular Gap Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method to inspect the pressure within the sealed annular space between a pipe and a wall type structure, as well as to evaluate the sealing performance of seals on both sides of the structure, which is not effectively addressed by existing solutions.
Innovation Solution
A test port assembly that replaces a bolt in the Innerlynx® Modular Mechanical Seals system, featuring a drilled hole and counterbore to accommodate a nipple for pressure application, allowing for the attachment of an inlet assembly with a pressure gauge, enabling periodic inspection and evaluation of the sealed annular gap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealed annular gap is created between two seals to prevent matter traversal, then sealing performance is improved, but the ability to inspect pressure and evaluate seal performance deteriorates
Solution Approach 1:
A test port assembly serves as an intermediary device that provides access to the sealed annular gap without compromising the seal integrity. The test port includes a body with a sealed chamber that can be connected to pressure gauges or other inspection devices, allowing pressure measurement and seal evaluation while maintaining the sealed condition of the annular gap.
2Reliability
If seals are installed on both sides of a wall type structure to prevent matter traversal, then sealing reliability is improved, but device complexity increases
Solution Approach 1:
The test port assembly is designed as a multi-functional device that combines several functions into a single unit: it provides pressure measurement capability, seal evaluation functionality, and maintains sealed annular gap integrity. This universal design reduces the need for multiple separate components and simplifies the overall system while maintaining high sealing reliability.
