Internal Valve Tank Connection Structure for Leak-Safe Gas Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-pressure gas tank connection structures require significant time and effort to connect the tank to a supply member due to the external placement of valves and pipes, leading to inefficiencies in gas supply and potential leaks.
Innovation Solution
A high-pressure gas tank connection structure featuring a tubular tank main body with internal connectors and a valve body positioned deeper within the tank, allowing for easy connection to a supply member without external valves, and incorporating sealing members to prevent gas leaks and pressure release through orthogonal lateral holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plural pipes and valve are provided externally to form gas flow paths, then gas supply function is achieved, but connection time and effort increase significantly
Solution Approach 1:
The patent merges the valve body and connection connectors into a single integrated structure. The first connection connector is formed integrally with the valve body, and the second connection connector is formed integrally with the tank mouthpiece, eliminating the need for separate external pipes and reducing connection steps to merely joining these integrated components.
Solution Approach 2:
The valve body serves multiple functions simultaneously: it controls gas flow through the valve mechanism and provides connection points for both the first and second connection connectors. This multi-functional design consolidates what would traditionally require separate components, reducing overall connection complexity.
2Device complexity
If valve body is positioned externally, then gas flow control is achieved, but connection complexity increases
Solution Approach 1:
The valve body and connection connectors are merged into one integral component. The first connection connector is formed as part of the valve body structure, reducing the number of separate parts that need to be assembled and sealed, thereby simplifying the overall connection structure.
Solution Approach 2:
The first connection connector is nested within or integrated with the valve body structure, with the valve mechanism positioned deeper inside the tank. This nested arrangement reduces external complexity while maintaining all necessary functions within a compact integrated unit.
3Reliability
If multiple external components are used for gas supply, then flow path functionality is achieved, but potential leak points increase
Solution Approach 1:
By integrating the connection connectors with the valve body and tank mouthpiece, the patent reduces the number of separate connection interfaces. Fewer interfaces mean fewer potential leak points, improving sealing reliability while maintaining gas flow control functionality.
Solution Approach 2:
The patent extracts and eliminates unnecessary external pipes and intermediate components from the traditional gas supply system. By removing these extra external elements and replacing them with integrated connectors, the design reduces potential leak sources while maintaining essential gas supply functionality.

AI summary
A high-pressure gas tank connection structure including: a tank main body; a tank side connector; a connection side connector; and a valve body, the valve body being provided further toward a deep side along the axial direction of the tank main body than the tank side connector, the valve body being urged toward the connection side connector, and, in a case in which the valve body is pushed by a distal end of the convex portion in a state in which the convex portion is joined with the concave portion, the valve body being opened from a closed state, and communicating the interior of the tank main body with the exterior to the tank main body.
