Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure maintaining gas cylinder valves face challenges in manufacturing costs and volume due to complex manufacturing processes and eccentric axis alignment of pressure retaining devices, leading to increased production costs and larger valve sizes.
Innovation Solution
A pressure maintaining gas cylinder valve design where the pressure retaining device's axis is aligned vertically with the valve element's axis, featuring a laterally arranged mounting base with a spring and valve mechanism that allows for horizontal movement, reducing volume and manufacturing costs by eliminating intersections and optimizing gas circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the pressure retaining device is installed with its axis perpendicular to the valve element's axis, then the manufacturing process becomes simpler, but the volume and weight of the cylinder valve increase
Solution Approach 1:
The pressure retaining device is repositioned from a perpendicular mounting (requiring additional lateral space) to a collinear mounting along the same vertical plane as the valve element. This dimensional reconfiguration allows the pressure retaining device to be integrated within the existing valve body footprint, reducing overall valve volume while simplifying the manufacturing process by eliminating complex angular intersections.
2Ease of manufacture
If the pressure retaining device is installed with its axis perpendicular to the valve element's axis, then the manufacturing process becomes simpler, but the manufacturing costs increase
Solution Approach 1:
The pressure retaining device is merged with the valve element assembly by aligning their axes in the same vertical plane. This consolidation allows both components to share common mounting structures and support mechanisms, reducing the number of separate manufacturing operations and assembly steps required, thereby lowering overall manufacturing costs despite maintaining process simplicity.
3Volume of moving object
If the pressure retaining device is installed with its axis in the same vertical plane as the valve element, then the volume and manufacturing costs are reduced, but the gas circulation path becomes more complex
Solution Approach 1:
The gas circulation path is segmented into distinct zones: a front side gas channel and a rear side gas channel separated by the pressure retaining device cylinder. Gas flows through the front channel to the air outlet, while additional circulation occurs through the rear channel. This segmentation allows compact integration of the pressure retaining device while maintaining efficient, separate gas flow paths that do not interfere with each other.
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
The design reduces the cylinder valve's volume, saves manufacturing costs, and ensures smooth gas flow while maintaining effective pressure retention, preventing gas from being completely used up and ensuring gas purity.
Implementation Method 1
a spring and a valve are located in the mounting base described: The valve described is located in the valve element near the air outlet; the front section of the valve is near the air outlet for opening/closing the air outlet, while the rear section of the valve is located in the mounting base and can move laterally along the mounting base; the spring described is located between the valve and the mounting base for pushing the valve to close the air outlet.

AI summary
The invention relates to a pressure maintaining gas cylinder valve. It consists of a pressure retaining device: The axis of the pressure retaining device and that of the valve element are in the same vertical plane; the pressure retaining device has a mounting base, a spring and a valve are located in the mounting base: the valve is in the valve element near the air outlet; the front section of the valve is near the air outlet, while the rear section of the valve is in the mounting base; the spring is between the valve and the mounting base. Because the invention has no eccentricity, the gas channel is smoother and the volume of the cylinder valve is greatly reduced. The mounting seat of the pressure retaining device not only provides support for the valve and spring, but also ensures that the stroke of the valve element is not interfered.
