Integrated Test and Drain Valve for Fire System Pressure Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire suppression systems lack a single component that efficiently facilitates testing, draining, and pressure venting, requiring separate components for each function.
Innovation Solution
A test valve integrating a drain, relief, and test assembly within a single component to manage fluid communication between inlet and outlet, allowing selective coupling and uncoupling for testing, draining, and pressure relief.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components are used for testing, draining, and pressure venting, then each function can be performed independently, but the device complexity and number of components increases
Solution Approach 1:
The patent combines three separate functional components (test valve, drain valve, and relief valve) into a single integrated test valve assembly. This merger reduces the total number of components and simplifies the system while maintaining all necessary functions for testing, draining, and pressure relief operations in fire suppression systems.
Solution Approach 2:
The integrated test valve assembly is designed to perform multiple functions simultaneously - it can conduct system testing, drain water, and provide pressure relief through a single component. This multi-functionality eliminates the need for separate dedicated components for each operation, reducing complexity while preserving functional independence.
2Reliability
If multiple separate valves are installed for testing, draining, and relief, then each function is optimized, but the ease of operation and system simplicity decreases
Solution Approach 1:
By merging the test, drain, and relief functions into a single integrated assembly, the system becomes simpler to operate and install. Operators no longer need to manage multiple separate valves, reducing operational complexity while maintaining the optimized functionality of each individual function through dedicated internal mechanisms.
3Device complexity
If a single integrated component is used for testing, draining, and pressure venting, then device complexity is reduced, but the functional versatility may be compromised
Solution Approach 1:
The integrated test valve assembly achieves true multi-functionality by incorporating separate internal mechanisms for testing, draining, and pressure relief within a single component. Each function maintains its full capability and can be operated independently, ensuring that the integration does not compromise functional versatility or adaptability.

AI summary
A test valve including a body, a test assembly, a relief assembly, and a drain assembly. The body includes an inlet, an outlet, an internal wall isolating the inlet from the outlet, and a drain opening, a relief opening, and a test opening defined by the internal wall and structured to facilitate fluid communication between the inlet and the outlet. The test assembly is structured to seal and unseal the test opening to selectively fluidly couple the inlet and the outlet. The relief assembly is structured to seal and unseal the relief opening to selectively fluidly couple the inlet and the outlet. The drain assembly is structure to seal and unseal the drain opening to selectively fluidly couple the inlet and the outlet.
