Reversible Valve Presetting for Maximum Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valves either lack the ability to adjust maximum flow or cannot reverse flow direction, limiting their functionality and maintenance simplicity.
Innovation Solution
A valve design that incorporates a presetting element allowing independent control of maximum flow and flow direction reversal, ensuring preset settings are maintained during flow direction changes, utilizing a handle and valve top mechanism for rotation and locking to achieve these functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a valve allows flow direction reversal by rotating an insert, then the valve can adapt to different flow directions, but the maximum flow through the valve cannot be adjusted
Solution Approach 1:
The presetting element is designed to perform multiple functions: it adjusts the maximum flow through the valve and simultaneously prevents unwanted rotation of the insert. This multi-functionality resolves the contradiction by integrating flow adjustment capability into the existing flow reversal mechanism without adding separate complex components.
Solution Approach 2:
The patent combines the presetting element with the insert assembly, where the presetting element is received by the insert and rotates together with it. This merging of functions allows the valve to both reverse flow direction and adjust maximum flow through a unified mechanism, avoiding the need for separate adjustment devices.
2Productivity
If a presetting mechanism is added to adjust maximum flow, then the valve can control flow rate, but the valve cannot reverse flow direction
Solution Approach 1:
The presetting element serves dual purposes: controlling maximum flow rate and enabling flow direction reversal. When the insert rotates to change flow direction, the presetting element rotates with it, maintaining the flow control setting while adapting to the new direction. This resolves the contradiction by making a single component responsible for both functions.
Solution Approach 2:
The presetting element is designed to be dynamically coupled with the insert, rotating together when the insert changes orientation. This dynamic connection ensures that flow control settings are maintained during flow direction reversal, allowing the valve to adaptively maintain productivity across different operational modes.
3Adaptability or versatility
If the insert is rotated to reverse flow direction, then the valve adapts to different flow directions, but the presetting may be changed or lost
Solution Approach 1:
The presetting element is designed with a preliminary engagement mechanism that establishes a stable reference position before rotation occurs. The cut-out geometry is predetermined to engage with the housing at specific positions, ensuring that when rotation happens, the presetting returns to or maintains its intended configuration rather than becoming random or lost.
Solution Approach 2:
The interaction between the cut-out in the presetting element and the corresponding feature in the housing provides positional feedback during rotation. This feedback mechanism ensures that the insert and presetting element align correctly after rotation, maintaining the presetting stability while allowing flow direction reversal.
