Pressure relief valve with stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of pressure relief valves is time-consuming and labor-intensive due to the need for precise alignment and proper tightening of components, which affects their functionality and requires frequent replacement every five years.
Innovation Solution
A pressure relief valve with a stop feature ensures proper alignment and tightening of components, reducing installation time and labor through alignment indicators and sealing mechanisms like chamfers and stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pressure relief valves are installed without alignment indicators, then the installation process requires manual alignment which is time-consuming and labor-intensive, but adding alignment indicators increases device complexity
Solution Approach 1:
The stop features are pre-integrated into the valve body and valve head during manufacturing, providing built-in alignment indicators that guide proper positioning before installation. This preliminary preparation eliminates the need for manual alignment adjustments during installation, directly improving installation speed without requiring additional external alignment devices
Solution Approach 2:
The stop features automatically indicate when the valve components are properly aligned through their physical geometry. The installer simply needs to observe when the stops align, and the valve self-indicates its correct positioning without requiring external tools or complex adjustment mechanisms, thus improving productivity while maintaining simple structure
2Ease of operation
If pressure relief valves lack proper alignment features, then installation requires more labor and time for precise alignment, but adding such features increases manufacturing complexity
Solution Approach 1:
The alignment indication function is segmented into distinct stop features on different components (valve body and valve head). These segmented stops work together to provide comprehensive alignment guidance, making the installation process easier while keeping each individual component's manufacturing relatively simple
Solution Approach 2:
The stop features utilize asymmetric geometric shapes that naturally guide the valve components into the correct relative positioning. This asymmetric design provides intuitive alignment guidance during installation while being straightforward to manufacture using conventional machining processes
3Reliability
If pressure relief valves are installed without built-in alignment indicators, then frequent replacements occur due to improper installation, but adding indicators increases device complexity
Solution Approach 1:
The stop features are pre-configured during manufacturing to indicate the correct installation position. This preliminary setup ensures that when the installer positions the stops correctly, the valve is guaranteed to be properly aligned and sealed, thereby ensuring reliable functionality and reducing failures due to improper installation
Solution Approach 2:
The stop features provide immediate visual and tactile feedback during installation, allowing the installer to know when proper alignment has been achieved. This feedback mechanism ensures correct installation without requiring complex monitoring systems, thereby improving reliability while maintaining simple structure

AI summary
A pressure relief valve with a stop disposed thereon to ensure components of the pressure relief valve are properly aligned and tightened properly. This allows the components and pressure relief valve to be properly installed and the pressure relief valve to function properly. The stop feature also reduces the time of installation and amount of labor needed to install pressure relief valves and their components.
