Fire Extinguisher Valve Mechanical Actuator Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manually operated fire extinguishing systems rely on human intervention for activation, which can be unreliable in detecting and responding to fires effectively.
Innovation Solution
A fire extinguisher valve with a mechanical actuator, comprising an elastic element and trigger mechanism, allows for automated or remote activation by moving a manual lever from a closed to an open position, enhancing the reliability of fire extinguishing systems without requiring integration with other system components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manually operated fire extinguishing system is used, then the system structure remains simple, but the reliability of fire detection and activation deteriorates due to dependence on human intervention
Solution Approach 1:
The fire extinguishing system performs self-activation through the mechanical actuator that automatically moves the manual lever from closed to open position when the actuator is triggered, eliminating the need for human intervention while maintaining system simplicity
Solution Approach 2:
The manual lever is pre-positioned in the closed position and the mechanical actuator is pre-configured to automatically open the valve when activated, allowing the system to be ready for immediate automated response without requiring complex pre-programming
2Extent of automation
If a mechanical actuator is added to enable automated operation, then the extent of automation improves, but the device complexity increases due to additional components
Solution Approach 1:
The mechanical actuator is designed as a separate, modular component that can be independently mounted to the valve body, allowing the automation function to be added without redesigning the entire valve system and enabling easier maintenance and replacement
Solution Approach 2:
The mechanical actuator serves multiple functions: it provides automated valve opening capability, maintains a compact structure through integrated mounting, and enables both manual and automated operation modes, making the system versatile

AI summary
A fire extinguisher valve for controlling a flow of a fire extinguishing agent in a fire extinguishing system comprises a valve body; a manual lever, which is manually movable between an open position, in which a fire extinguishing agent discharge path through the valve body is established, and a closed position, in which the fire extinguishing agent discharge path through the valve body is closed; and a mechanical actuator, which is mounted to and supported by the valve body. The mechanical actuator comprises an actuation element for acting upon the manual lever for moving the manual lever from its closed position to its open position; an elastic element for moving the actuation element, and a trigger mechanism for holding the actuation element in a preloaded position, in which the elastic element is preloaded, and for releasing the actuation element, when the mechanical actuator is activated.
