Cask Vehicle Valve with Dual Elastic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cask vehicles face issues with material unloading due to pressure differences trapping material in conveying means, and existing gate-like valves are inefficient in sealing, especially with solid bodies, requiring cumbersome and time-consuming mechanical operations, and are costly to construct.
Innovation Solution
A cask vehicle with a valve system featuring a shutter body and dual elastic sealing means for two-way sealing, along with unloading means that automatically equalize pressure to facilitate trapped material release when the valve is closed, reducing the need for manual and stressful unloading procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gate-like valves with elastic outer profile are used for two-way sealing, then sealing capability is improved, but solid bodies can become trapped between the profile and shutter blade causing leakage
Solution Approach 1:
The single elastic outer profile is segmented into two separate elastic sealing elements positioned on opposite sides of the shutter blade. This segmentation prevents solid bodies from becoming trapped between the shutter and sealing surface, as each sealing element independently contacts its respective face without creating escape zones for solid contaminants.
Solution Approach 2:
The two elastic sealing elements act as intermediaries between the shutter blade and the valve body bore, providing a compliant sealing interface that accommodates solid bodies in the slurry without creating leakage paths. The elastic material deforms to maintain sealing contact while allowing solid particles to pass through.
2Ease of manufacture
If conventional valve designs are used, then construction cost is reduced, but unloading of trapped material requires time-consuming mechanical operations
Solution Approach 1:
The valve system provides self-service unloading functionality through the dual sealing element design. When the valve closes, the two elastic sealing elements compress the trapped material between them, automatically expelling it without requiring external mechanical intervention. This eliminates the need for time-consuming manual unloading operations while maintaining a relatively simple valve construction.
3Reliability
If pressure difference is maintained for sealing, then sealing effectiveness is improved, but material becomes trapped in conveying means
Solution Approach 1:
The pressure difference that normally causes material to be trapped in the conveying means is converted into a beneficial force by the dual sealing elements. When the valve closes, the elastic sealing elements compress the trapped material using the existing pressure differential, transforming the harmful trapping effect into a useful self-unloading mechanism that expels material efficiently.
