Adjustable Cage Assembly for Variable Flow Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flow control devices often require adjustable flow restrictions to manage fluid flow rates effectively, but existing solutions are either costly or complex, necessitating the replacement of entire devices to achieve desired flow rates.
Innovation Solution
An adjustable restriction cage assembly comprising two cage bodies with locking features, allowing for rotational alignment to vary the flow opening size, providing a range of flow control settings without replacing the entire device, and incorporating features like ribs and grooves for secure alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If entire flow control devices are replaced to achieve desired flow rates, then flow control precision is improved, but device complexity and cost increase
Solution Approach 1:
The flow control device is segmented into a stationary body and a rotatable cage assembly with multiple independently adjustable restrictors. Each restrictor can be adjusted separately to control flow through different passages, allowing precise flow rate control without replacing the entire device. The cage body is divided into multiple radial positions, each with adjustable restrictors that can be independently positioned.
Solution Approach 2:
The restrictors are made dynamically adjustable through rotational movement of the cage body relative to the stationary body. The cage assembly can rotate to different angular positions, allowing the restrictors to align with different passages and create variable flow restrictions. This dynamic adjustment mechanism enables continuous flow rate control without device replacement.
2Adaptability or versatility
If multiple flow control settings are implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The cage assembly serves multiple functions: it houses multiple restrictors, provides rotational adjustment mechanism, and controls flow through multiple passages simultaneously. The same cage body structure enables control over different fluid streams or pathways by rotating to different angular positions, providing universal flow control capability without requiring separate devices for each function.
Solution Approach 2:
The restrictors are nested within the cage body structure, with each restrictor positioned in a radial slot that allows independent adjustment. The cage assembly is nested within the stationary body, creating a compact multi-layered structure where multiple flow control elements are integrated into a single compact unit, reducing overall device complexity while maintaining multiple settings.

AI summary
An adjustable cage assembly for a flow control device can include a first cage body and a second cage body. The first cage body can be rotationally fixed relative to the second cage body at a plurality of alignments to provide a flow opening of variable size for adjustable control of fluid flow areas through the adjustable cage assembly.
