Valve System for Gas Bottle Bundle with Bellows Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve systems for gas cylinder bundles are not permanently technically tight, requiring continuous monitoring for leak tightness, which is time-consuming and costly, and are not compatible with all gas supply systems, especially those that do not allow permanent connections.
Innovation Solution
A valve system with permanently technically tight connections using screw connections, such as internal and external threads, and sealing units like ball valves or diaphragm seals, allowing for both permanent and non-permanent connections, ensuring the system remains leak-tight without continuous monitoring, and is compatible with various gas supply systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional valve systems are used for gas cylinder bundles, then the system can be filled and discharged, but continuous monitoring for leak tightness is required which is time-consuming and costly
Solution Approach 1:
The patent replaces mechanical sealing systems with bellows seals and diaphragm seals that provide inherent leak tightness. The bellows seal (19) and diaphragm seal (20) create a permanently technically tight connection that eliminates the need for continuous monitoring, substituting mechanical monitoring requirements with self-sealing mechanical design.
Solution Approach 2:
The patent changes the sealing parameter from traditional valve seals to bellows and diaphragm seals that achieve a process index of 0.25, representing a permanently technically tight connection. This parameter change in sealing technology eliminates the need for continuous monitoring and reduces both time and cost.
2Reliability
If traditional valve systems are used for gas cylinder bundles, then the system can be filled and discharged, but continuous monitoring and regular servicing are required which increases cost
Solution Approach 1:
The patent replaces traditional mechanical valve seals with bellows seals (19) and diaphragm seals (20) that provide inherent leak tightness. This mechanical substitution eliminates the need for regular servicing and monitoring, significantly reducing maintenance costs while improving reliability.
Solution Approach 2:
The bellows seal and diaphragm seal designs are self-sealing and do not require external monitoring or regular servicing. The system serves itself by maintaining permanent technical tightness through its inherent mechanical design, eliminating the need for continuous human intervention and reducing maintenance costs.
3Reliability
If permanent connections are used for gas supply systems, then leak tightness is improved, but compatibility with mobile gas filling systems is reduced
Solution Approach 1:
The patent creates a universal connection system that can function in both permanent and mobile applications. The valve system with bellows seal and diaphragm seal provides permanent technical tightness while being compatible with various gas supply systems including mobile filling systems, achieving multi-functionality across different application scenarios.
Solution Approach 2:
The valve system acts as an intermediary that bridges permanent and mobile connection requirements. The bellows seal (19) and diaphragm seal (20) provide a permanent technical tight connection that can interface with both fixed gas supply infrastructure and mobile filling systems, mediating between these two application types.

AI summary
The invention relates to a valve system (10; 10'; 10''; 10'''; 10a, 10b) for a transportable, refillable gas bottle bundle (12a, 12b) and/or to a gas bottle group (100) comprising – a first gas line connection (18; 18') having a screw connection (30; 31) suitable for durably gas-tight connections, which screw connection is designed to connect the first gas line connection (18; 18') to a first outward line (44; 44a, 44b, 44c, 44d) in a durably gas-tight manner, – at least one second gas line connection (22, 22a, 22b) having a screw connection (30; 31) suitable for durably gas-tight connections, which screw connection is designed to connect the second gas line connection (22, 22a, 22b) to an inward line (42), a gas line connection unit (38) and/or a gas bottle (14a, 14b) in a durably gas-tight manner, and – at least one valve system line (20) connecting the first gas line connection (18; 18') and the at least one second gas line connection (22, 22a, 22b) in a durably gas-tight manner, wherein the valve system (10; 10'; 10''; 10a, 10b) has a connection sealing unit (32) which has a closed state and at least one open state and is arranged and designed such that, in the closed state, it prevents a gas flow through a lumen (36) of the first gas line connection (18; 18') and, in the at least one open state, permits a gas flow through the lumen (36) of the first gas line connection (18; 18').
