Quick-Opening Valve Layout to Minimize Extinguisher Recoil
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Quick-opening valves for pressurized extinguishing fluid vessels often cause lateral movement of the vessel due to the angle of fluid exit, posing a safety risk and requiring larger dimensions to manage pressure loss and flow resistance.
Innovation Solution
The extinguishing fluid inlet and outlet are oriented substantially parallel or coaxial to minimize lateral movement, with a resetting mechanism, a differential pressure piston design, and an overpressure safety device to ensure safe and efficient fluid discharge without uncontrolled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the extinguishing fluid inlet and outlet are arranged at right angles in known quick-opening valves, then the valve structure is compact, but lateral movement impetus is generated causing safety risks and uncontrolled vessel movement
Solution Approach 1:
The patent inverts the conventional right-angle arrangement of inlet and outlet by orienting them substantially parallel to each other. This inversion eliminates the lateral impetus generation while maintaining valve functionality, directly resolving the safety issue without requiring complex additional components
2Reliability
If the extinguishing fluid inlet and outlet are arranged at right angles, then the valve can be compact, but the extinguishing fluid vessel may spin around or move laterally in uncontrolled fashion
Solution Approach 1:
By inverting the conventional angular arrangement to a parallel arrangement, the patent eliminates lateral movement impetus while preserving controlled fluid discharge. The parallel orientation ensures that reaction forces act along the longitudinal axis, maintaining both stability and operational control
3Device complexity
If conventional quick-opening valves are used with angular inlet/outlet arrangement, then the valve structure is simpler, but larger dimensions are required to manage pressure loss and flow resistance
Solution Approach 1:
The patent inverts the conventional angular geometry to a parallel configuration, which reduces flow resistance and pressure loss by eliminating sharp directional changes in fluid flow. This geometric inversion allows for more compact dimensions while maintaining efficient fluid discharge
