Pressurized Gas Line Inversion for Dry Preload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for filling vessels fail to prevent liquid and foam particles from entering the pressurized gas line, leading to foam formation during the filling of carbonated or hot beverages, which compromises the 'dry preload' mechanism.
Innovation Solution
The pressurized gas line is designed with a short, open bottom section between the prestressing valve and the gas space, ensuring no liquid penetration, and is connected to a correction gas source via additional valves, allowing it to function as a parallel gas path to the return gas pipe, preventing liquid and foam entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pressurized gas line opens into the gas space with an upward-directed opening, then gas can be supplied to the vessel, but liquid and foam particles can penetrate into the gas line and collect above the clamping gas valve
Solution Approach 1:
The patent inverts the conventional design by making the pressurized gas line open at the bottom instead of the top. This reversal prevents liquid and foam particles from entering the gas line, as they naturally flow downward due to gravity而不能进入向上延伸的气路。The upwardly directed opening is replaced with a downwardly directed opening that discharges into the gas space, ensuring the gas line remains dry.
Solution Approach 2:
The patent extracts the harmful element (liquid and foam particles) from the gas line by redesigning the opening direction. The pressurized gas line is separated from the liquid phase by opening it in the opposite direction (upward discharge instead of downward intake), effectively removing the contamination risk while maintaining gas supply function.
2Reliability
If a separate pressurized gas line is used to bypass the return gas pipe, then liquid residue in the return gas pipe is avoided, but the pressurized gas line becomes vulnerable to liquid penetration through upward openings
Solution Approach 1:
The patent applies inversion by reversing the opening direction of the pressurized gas line. Instead of opening upward into the gas space (which would allow liquid entry), it opens downward and discharges upward, creating a physical barrier against liquid penetration while maintaining the separate gas supply path.
3Reliability
If the pressurized gas line has a long path from the prestressing valve to the gas space, then gas distribution is improved, but liquid penetration risk increases
Solution Approach 1:
The patent resolves this contradiction by inverting the opening direction. The pressurized gas line can extend to ensure proper gas distribution, but the upwardly directed opening prevents liquid from traveling up the line, effectively decoupling the length advantage from the liquid penetration risk.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design ensures absolutely dry prestressing of vessels, even under unfavorable conditions, by preventing liquid and foam particles from entering the gas line, maintaining the integrity of the 'dry preload' mechanism.
Implementation Method 1
The area of the pressurized gas line between the prestressing valve and the opening into the gas space is relatively short and open at the bottom, so that in practice no liquid parts can penetrate
