Regulating Valve Rotating Disc Angular Position Gas Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Regulating valves for gas cooking appliances face challenges in efficiently adapting to different types of combustible gases without requiring modifications or replacements of the rotating disc, leading to increased costs and complexity.
Innovation Solution
The design allows the rotating disc to be positioned at different angular positions to accommodate various gases, with the operating means adjusted to change the disc's position relative to a reference, enabling easy adaptation to different gas types without replacing the disc, thus reducing the number of required parts and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rotating disc is replaced or modified to accommodate different gas types, then the valve can supply different types of combustible gas, but the number of parts increases and valve costs increase
Solution Approach 1:
The rotating disc is made adjustable in its angular position rather than being fixed. The disc can be rotated to different angular positions corresponding to different gas types, and operating means can change the disc's position relative to a reference position. This dynamic adjustment allows a single disc to serve multiple gas types without replacement or modification.
Solution Approach 2:
The angular position of the rotating disc is changed as a parameter to adapt to different gas types. By varying the angular position parameter, the valve can supply different combustible gases (natural gas, propane, butane) using the same physical disc, thereby avoiding the need to replace or modify the disc for each gas type.
2Adaptability or versatility
If the rotating disc is replaced or modified for different gas types, then the valve can be adapted to different gases, but valve costs increase
Solution Approach 1:
The rotating disc is designed to perform multiple functions by being adjustable to different angular positions. A single disc design can accommodate natural gas, propane, and butane supply by simply changing its angular position, making the valve universal for different gas types and eliminating the need for multiple specialized discs, thus reducing manufacturing costs.
Solution Approach 2:
The disc's angular position is made dynamic and adjustable rather than fixed for each gas type. This allows the same disc to be reused for different gases by repositioning, reducing the need for multiple disc inventories and lowering overall valve system costs.
3Device complexity
If the rotating disc position is fixed, then the valve structure is simple, but the valve cannot adapt to different gas types without replacement or modification
Solution Approach 1:
The rotating disc's angular position is made adjustable through operating means while maintaining a relatively simple overall valve structure. The disc can be rotated to different positions and locked, providing adaptability without requiring complex mechanisms. This dynamic positioning capability allows the valve to adapt to different gas types while keeping the structural complexity manageable.

AI summary
Regulating valve for a gas cooking appliance according to one embodiment includes a valve body with an inlet conduit, at least one outlet conduit and an inner cavity in fluid communication with the inlet conduit. The regulating valve also includes a rotating disc in contact with a wall of the valve body that partially defines the inner cavity. The rotating disc includes at least one connecting opening for regulating the gas flow between the inner cavity and the outlet conduit by means of rotation. Operating means is connected to the rotating disc for rotating it. The regulating valve is adapted for supplying different types of combustible gas, the rotating disc being arranged in a different angular position, depending on the type of gas to be supplied, when the operating means is arranged in a reference position.
