Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas sampling technologies face challenges in efficiently collecting, transporting, and analyzing gas samples from pressurized containers, particularly in industrial contexts like oil and gas exploration and natural gas storage, where periodic sampling is required for data acquisition and chemical tag identification.
Innovation Solution
A valve assembly and chuck system for a gas sampling apparatus, comprising a first core valve with a biased pin, a second core valve with a biased pin, and a transfer tube that isolates fluid communication paths between these valves, allowing for controlled fluid transfer and sealing mechanisms to maintain pressurized conditions during sampling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pressurized gas sampling system uses multiple core valves with fluid communication paths, then gas sample collection and transfer capability is improved, but the risk of fluid leakage and loss of pressurized conditions increases
Solution Approach 1:
The system divides the fluid communication path into separate isolated segments, with each core valve (first core valve, second core valve) operating in its own isolated fluid pathway. The transfer tube provides a dedicated isolated channel for sample transfer between valves, preventing cross-contamination and maintaining sealing integrity in each segment independently.
Solution Approach 2:
The transfer tube acts as an intermediary component that facilitates controlled fluid communication between the first and second core valves while maintaining isolation from other fluid paths. This intermediary structure enables reliable sample transfer without direct exposure to multiple pressurized pathways simultaneously.
2Reliability
If the system maintains isolated fluid communication paths between core valves, then sealing reliability is improved, but device complexity increases
Solution Approach 1:
The transfer tube is integrated into the chuck system housing, combining the transfer function with the existing structural framework. The first and second core valves are mounted on the same chuck system, allowing shared support structures and control mechanisms while maintaining isolated fluid paths through the integrated design.
Solution Approach 2:
The chuck system serves multiple functions: it houses the transfer tube, provides mounting for both core valves, and maintains the isolated fluid communication paths. This multi-functional design reduces the need for separate dedicated components for each function, thereby reducing overall system complexity despite the multiple valves and isolated paths.

AI summary
A valve assembly and chuck system for a gas sampling apparatus. In one embodiment, the apparatus may comprise a valve assembly comprising a first core valve, wherein a pin of the first core valve is biased to a first closed position; a chuck system comprising a second core valve, wherein a pin of the second core valve is biased to a first closed position; and a transfer tube housed within the chuck system, wherein the transfer tube provides a means of displacing the pins of the first and second core valves to a second open position; wherein the transfer tube isolates a fluid communication path between the first and second core valves. In an alternate embodiment, the chuck system may not comprise a second core valve, and the transfer tube may isolate a fluid communication path between the first core valve and the chuck system.
