Valve Control System Dual-Timing Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve control systems lack a reliable mechanism to ensure fluid valves are closed in power failure scenarios, as they often rely on motor or solenoid-based mechanisms that may fail or require manual intervention, leading to potential fluid leaks or uncontrolled flow.
Innovation Solution
A dual-timing system comprising a primary and secondary valve timing system, where the primary system closes the valve after a first period and the secondary system, which includes a secondary vent valve, automatically closes the valve after a longer second period, ensuring fluid control even in power failures or primary system malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single valve timing system is used, then the device complexity is reduced, but the reliability of valve closure in power failure conditions deteriorates
Solution Approach 1:
The valve timing system is segmented into two independent subsystems: a primary valve timing system with a first vent valve and timing control module, and a secondary valve timing system with a second vent valve and timing control module. Each subsystem can independently control the valve closure timing, ensuring that if one system fails, the other can still reliably close the valve even in power failure conditions.
Solution Approach 2:
The two timing systems are configured with different timing parameters - the primary system closes the valve after a first period of time, while the secondary system closes the valve after a second period of time that is longer than the first period. This parameter differentiation ensures that the secondary system provides a backup closure mechanism with extended timing, maintaining reliability without requiring identical complex systems.
2Ease of operation
If motor or solenoid-based closing mechanisms are used, then the ease of operation is improved, but the reliability in power failure scenarios deteriorates
Solution Approach 1:
The valve closing mechanism utilizes pneumatic principles through vent valves that control fluid pressure to actuate the valve closure. The timing control modules regulate the venting of fluid pressure over specific time periods, enabling automatic valve closure without relying on motor or solenoid mechanisms that fail during power outages. The pneumatic system maintains operational reliability by using stored fluid pressure as the energy source.
3Productivity
If automatic valve closure is implemented, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The timing control modules are pre-configured with predetermined time periods (first period for primary system, second period for secondary system) that automatically trigger valve closure after valve opening. This preliminary timing setup eliminates the need for complex real-time decision-making during operation, enabling automatic valve control with simplified logic while maintaining high productivity through rapid automated response.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dual-timing system ensures reliable valve closure in both normal and power failure conditions, preventing fluid leaks and maintaining control over fluid flow by automatically switching to the secondary system if the primary system fails.
Implementation Method 1
The secondary vent valve may be operable to communicate fluid from the environment to the valve such that the valve moves from the open position to the closed position
Data Source
AI summary
A fluid control system includes a valve, an actuator, a primary valve timing system, and a secondary valve timing system. The valve is operable in an open position and a closed position. The actuator is operable to move the valve from the closed position to the open position. The primary valve timing system is in communication with the actuator and is operable to move the valve from the open position to the closed position after a first period of time. The secondary valve timing system is in communication with the actuator and is operable to move the valve from the open position to the closed position after a second period of time.
