High-Pressure Gas Fitting Leak Indicator for Hub Seal Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamp connectors in high-pressure gas systems face challenges in aligning hubs for a gas-tight seal, making it difficult to detect leaks, which can lead to hazardous situations due to undetected gas leaks and prolonged downtime.
Innovation Solution
A gas leak indication system comprising a ring with a flange and flow opening, an extender, an indicator, and a cap, which together form a flow detection system that exposes the indicator when a leak occurs, allowing immediate visual detection of leaks and controlling the gas flow to prevent hazardous conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamp connectors are used to join hubs in high-pressure gas systems, then gas transport is enabled, but alignment difficulty causes sealing failures and undetected leaks
Solution Approach 1:
The patent introduces a hub alignment tool as an intermediary device between the two hubs to be joined. This tool includes alignment features that physically guide the hubs into proper alignment during the clamping operation, eliminating the need for difficult manual alignment while ensuring reliable sealing contact between the hub surfaces.
Solution Approach 2:
The alignment tool is designed to establish proper hub alignment before the final clamping action occurs. By pre-positioning the hubs in correct alignment using the tool's guidance features, the sealing surfaces are guaranteed to be properly oriented before pressure is applied, preventing sealing failures.
2Reliability
If traditional leak detection methods are used, then system monitoring is possible, but detection delay leads to prolonged downtime and hazardous conditions
Solution Approach 1:
The clamp connector incorporates integrated leak detection features directly into its structure, such as visual indicators or pressure-sensing elements that automatically detect and signal leaks without requiring external monitoring equipment. This self-diagnostic capability enables immediate leak identification, eliminating detection delays and allowing rapid response to prevent hazardous conditions.
3Manufacturing precision
If manual alignment procedures are used for hubs, then assembly is possible, but alignment precision is insufficient for gas-tight seals
Solution Approach 1:
The hub alignment tool serves as a mechanical intermediary that translates rough manual positioning into precise alignment. The tool incorporates precision-machined alignment features such as tapered guides or keyed surfaces that automatically establish correct hub orientation when engaged, achieving high alignment precision while keeping the overall procedure simple through the use of this single specialized tool.

AI summary
Implementations of a gas leak indication system may include a ring including a flange extending from an interior surface of the ring, the flange including two seal channels on either side of the flange, and the ring including a flow opening extending into a projection extending from an exterior surface of the ring; an extender threadedly coupled into a side opening in the projection, the extender including a flow opening therethrough; an indicator threadedly coupled onto the extender, the indicator including a flow channel extending therethrough; and a cap coupled over an end of the indicator by a friction fit.
