Pipeline Device Isolation Portion with Slits for Leak Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In refrigeration systems, detecting leaks between adjacent cavities in pipeline devices is challenging due to the lack of visible indicators, making post-sales repairs difficult and inefficient.
Innovation Solution
The pipeline device incorporates an isolation portion with slits and spacing portions on the fitting plates, allowing for accurate detection of leaks by ensuring that any inleakage overflows through the slits, facilitating quick identification of leak points without affecting adjacent cavity performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If welding is used to fix the upper cover and lower cover, then the pipeline device achieves strong connection and sealing, but inleakage detection becomes difficult and post-sales repair becomes inefficient
Solution Approach 1:
The isolation portion is divided into multiple slits (first slits and second slits) that are spaced apart by spacing portions. This segmentation allows the isolation portion to maintain structural integrity while providing multiple potential leak detection points, making it easier to detect and locate inleakage without compromising the welded connection strength.
Solution Approach 2:
The isolation portion acts as an intermediary element between the first cavity and second cavity. It includes first slits penetrating the first fitting plate and second slits penetrating the second fitting plate, with spacing portions between adjacent slits. This intermediary structure allows refrigerant to potentially leak through the slits in a controlled manner, making inleakage detectable while maintaining the overall sealing of the welded connection.
2Measurement precision
If the isolation portion includes multiple slits with spacing portions, then inleakage detection precision is improved, but the device structure becomes more complex
Solution Approach 1:
The first slits and second slits are merged into a single isolation portion structure that spans across both the first fitting plate and second fitting plate. The spacing portions are integrated into this unified structure, allowing multiple detection functions to be achieved through a single combined component rather than separate elements, thereby reducing overall device complexity.
Solution Approach 2:
The isolation portion serves multiple functions simultaneously: it acts as a barrier between cavities, provides multiple leak detection points through its slits, and maintains structural integrity through its spacing portions. This multi-functionality reduces the need for additional separate components, simplifying the overall device structure while improving detection precision.
3Measurement precision
If the first slits and second slits are aligned to form arrangement path, then leak detection accuracy is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The spacing portions are designed with predetermined dimensions and positions before the actual slit formation process. By establishing the spacing portions first as reference features, subsequent slit machining can be positioned relative to these pre-established references, reducing the cumulative error and making the alignment process more manageable during manufacturing.
Solution Approach 2:
The isolation portion is designed to accommodate reasonable variations in slit alignment through its spacing portions. The spacing portions act as flexible elements that can absorb minor misalignments, allowing the system to maintain effective leak detection functionality even when manufacturing precision varies within acceptable tolerances, thereby reducing the stringency of precision requirements.
