Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire extinguishing system valves require significant installation space and effort for functional checks of pressure gauges, necessitating external fittings and complex venting mechanisms.
Innovation Solution
Integrate the venting function into the housing of the fire extinguishing system valve, incorporating a piston that moves between pressure transmission and venting positions to facilitate pressure gauge checks with minimal space and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external ball valves and fittings are used to vent pressure gauges, then pressure gauge functionality can be checked, but installation space and installation effort increase significantly
Solution Approach 1:
The venting function is merged with the valve housing by integrating a venting device directly into the housing structure. This eliminates the need for separate external ball valves and fittings, thereby reducing installation space while maintaining the ability to check pressure gauge functionality.
Solution Approach 2:
The valve housing is designed to serve multiple functions: it not only controls fluid flow through the closing body but also incorporates a venting device for pressure gauge checking. This multi-functionality reduces the need for additional external components and simplifies the overall system.

3Area of stationary object
If the venting function is integrated into the valve housing, then installation space and complexity are reduced, but the functional complexity of the housing increases
Solution Approach 1:
The venting device is designed as a separate, modular component that can be integrated into the valve housing. This segmentation allows the housing to maintain its primary function while adding the venting capability as a distinct functional module, making the overall design more manageable despite increased complexity.
Solution Approach 2:
A piston is introduced as an intermediary element within the venting device. This piston mediates between the pressure gauge and the external environment, controlling the venting process in a simple and reliable manner without requiring complex control mechanisms.

AI summary
The invention relates to a fire extinguishing system valve (1), having a housing (2), a fluid inlet chamber (11) provided in the housing (2), a fluid outlet chamber (13) provided in the housing (2), and a closing body (9) which can be moved back and forth between a blocked state and a released state. In the blocked state, the closing body (9) prevents a direct flow of fluid between the fluid inlet chamber (11) and the fluid outlet chamber (13) and in the released position, said closing body (9) connects the fluid inlet chamber (11) to the fluid outlet chamber (13) directly in a fluid-conducting manner. According to the invention, the fire extinguishing system valve (1) has at least one manometer (15, 17), which is operatively connected to the fluid inlet chamber (11) or fluid outlet chamber (13) and is mounted on the housing (2), and a ventilation device (21) for the at least one manometer (15, 17), said ventilation device (21) being integrated in the housing (2).
