Fire Extinguishing Nozzle Aperture Ring Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stationary fire extinguishing systems require significant time and structural adjustments to adapt to changing conditions, such as changes in space or extinguishing agents, and lack a straightforward method to verify the aperture diameter after installation, leading to potential misalignment and unnecessary nozzle replacements.
Innovation Solution
The extinguishing fluid nozzle system incorporates a grip portion with an identification element and an introduction opening that allows for easy installation and removal of apertures without removing the nozzle, featuring a guillotine-like movement and securement options like nuts and clamping elements, ensuring correct aperture size association and reducing maintenance complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If aperture openings are installed in the extinguishing nozzles to control flow quantity, then the flow rate can be limited, but it becomes difficult to verify the aperture diameter after installation and time-consuming to replace nozzles for adaptation
Solution Approach 1:
The aperture is separated from the nozzle body as an independent replaceable component. The aperture ring can be removed and replaced without removing the entire nozzle, allowing quick adaptation of flow characteristics by simply exchanging the aperture ring with different aperture diameters.
Solution Approach 2:
An identification element (such as a marking or code) is introduced as an intermediary between the aperture ring and the user. This identification element visible outside the nozzle indicates the aperture diameter, enabling verification without disassembly and preventing incorrect selection.
2Adaptability or versatility
If the nozzle structure is modified to adapt to changing space conditions or extinguishing agents, then the system can be customized, but significant structural adjustments and time are required
Solution Approach 1:
The nozzle system is designed with dynamic adaptability through the replaceable aperture ring. Instead of modifying the fixed nozzle structure, the system allows dynamic adjustment of flow characteristics by simply replacing the aperture ring, making the system adaptable to changing requirements without structural changes.
Solution Approach 2:
The nozzle body is designed as a universal component that can work with multiple aperture rings of different diameters. This multi-functionality allows the same nozzle body to be adapted to different flow rate requirements and application conditions by simply changing the aperture ring, eliminating the need for multiple specialized nozzle designs.
3Quantity of substance
If aperture rings are installed inside the nozzle to limit flow, then flow quantity can be controlled, but the aperture diameter cannot be easily verified after installation
Solution Approach 1:
An identification element serving as an intermediary is attached to the aperture ring and extends outwardly from the nozzle. This intermediary carries information about the aperture diameter in a visible form, allowing users to verify the aperture size without disassembling the nozzle or relying on memory.
Solution Approach 2:
The identification element may use color coding or visual markings to indicate different aperture diameters. This visual information system allows quick identification of the correct aperture size, preventing information loss and ensuring proper selection.

AI summary
An extinguishing fluid nozzle system (1, 100, 200), for stationary fire extinguishing systems, with an extinguishing fluid nozzle having a main body (3, 104, 204) which has an inlet opening (23, 123, 223) and can be fixed in fluid-conducting relationship to an extinguishing fluid line, a nozzle head (5, 106, 206) which has one or more outlet openings (25, 125, 225) connected in fluid-conducting relationship to the inlet opening for the discharge of the extinguishing fluid, and an aperture (7, 107, 207) having an aperture ring (15, 115, 215) for flow limitation, arranged in the fluid path between the inlet opening and the one or more outlet openings. The aperture has a grip portion (17, 117, 217) which is fixedly connected to the aperture ring and which extends outwardly from the aperture ring and which in the fitted condition of the aperture extends outside the extinguishing fluid nozzle.
