Rotary Spindle Valve Channel for Precise Fluid Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional stopcocks have limited flow control functionality due to their configuration, which can lead to unintended fluid flow prevention or excessive flow, and they only provide approximately 30° of spindle rotation between fully open and closed positions.
Innovation Solution
A valve design featuring a spindle with a channel around its circumference, where the depth and width of the channel change as the flow regulator rotates between open and closed positions, allowing for improved control of fluid flow, with a 50° rotation range and a handle for user or machine operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional stopcock configuration is used, then device simplicity is maintained, but flow control precision deteriorates
Solution Approach 1:
The valve body is segmented into distinct functional zones: an inlet port, an outlet port, and a spindle assembly with a channel. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity. The spindle with its circumferential channel creates discrete flow control zones that can be independently adjusted through rotation.
Solution Approach 2:
The invention introduces rotational movement as an additional dimension of control. Instead of linear adjustment, the spindle rotates to vary the channel's depth and width dynamically. This rotational dimension enables continuous flow control adjustment without complicating the basic valve structure, resolving the contradiction between precision and simplicity.
2Adaptability or versatility
If spindle rotation range is limited to 30°, then device simplicity is maintained, but flow control adjustability deteriorates
Solution Approach 1:
The flow control function and the rotation mechanism are merged into a single integrated spindle assembly. The spindle combines the flow channel, the rotation capability, and the flow regulation function in one component. This merging allows for an extended 50° rotation range without requiring separate complex mechanisms for each function, thereby increasing adaptability while controlling complexity.
3Measurement precision
If channel depth and width are fixed, then manufacturing simplicity is maintained, but flow control precision deteriorates
Solution Approach 1:
The channel geometry transitions from a fixed structure to a dynamic one that changes with spindle rotation. The channel's depth and width are no longer static but vary continuously as the spindle rotates between 0° and 50°. This dynamic geometry enables precise flow control adjustment while the manufacturing process remains relatively simple, as it involves creating a rotatable spindle with a circumferential channel rather than multiple complex components.

AI summary
A system that regulates a flow of a fluid through a valve is disclosed. The system includes a flow regulator and a spindle housing. The flow regulator includes a spindle that includes a channel that extends around a portion thereof and a flow adjuster that extends from the spindle. The spindle housing includes an aperture extending therethrough that receives the spindle, an inlet that receives the fluid and an outlet that expels the fluid. The flow regulator is rotatable relative to the spindle housing when the spindle is disposed in the aperture.
