Valve Control Assembly With Locking Positions for Precise Flow Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control assemblies for valves in cooling systems, particularly in data centers, lack the ability to provide customizable and cost-effective solutions for defining intermediate positions, are limited in application to specific orientations, and cannot accommodate the needs of three-way ball valves or valves requiring horizontal orientation, leading to issues with flow control accuracy and maintenance.
Innovation Solution
A control assembly featuring a guide body with locking features and a mounting structure that allows for customizable positioning of a valve handle, enabling precise alignment in various orientations, including three-way configurations, using a spring-biased plunger for secure engagement with the locking features, and is adaptable to both horizontal and vertical orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing control assemblies are used for valves, then the valve can be controlled for fluid flow, but the control assembly cannot provide customizable intermediate positions and is limited to specific orientations
Solution Approach 1:
The control assembly is segmented into distinct functional components: a guide body with multiple locking features, a handle with a locking member, and a valve member. The guide body is further segmented with multiple locking features at different angular positions, allowing the handle to be secured at various intermediate orientations. This segmentation enables customizable positioning while keeping each component relatively simple in structure.
Solution Approach 2:
The guide body serves multiple functions: it guides the handle rotation, provides multiple locking positions for intermediate orientations, and secures the handle in place. The locking member on the handle engages with different locking features to achieve various valve positions (fully open, fully closed, and intermediate positions). This multi-functionality increases adaptability without proportionally increasing overall device complexity.
2Manufacturing precision
If existing control assemblies are used for valves, then the valve can control fluid flow, but flow control accuracy is compromised due to inability to define intermediate positions
Solution Approach 1:
The guide body is pre-configured with multiple locking features at specific angular positions corresponding to desired valve orientations (fully open, fully closed, and intermediate positions). This preliminary arrangement of locking features ensures that when the handle is rotated, it will naturally align with and be secured at these pre-determined accurate positions, achieving both positioning accuracy and operational ease.
Solution Approach 2:
The locking member acts as an intermediary between the handle and the guide body's locking features. It engages with the specific locking feature corresponding to the desired valve position, providing positive mechanical alignment and securing the handle at the precise intermediate orientation needed for accurate flow control.
3Productivity
If existing control assemblies are used for valves, then the valve can be mounted, but maintenance efficiency is reduced due to lack of predefined flow configurations
Solution Approach 1:
The guide body is pre-configured with multiple locking features that correspond to predefined flow configurations (fully open, fully closed, and various intermediate positions). During maintenance, technicians can quickly return the valve to these pre-established configurations without needing to calculate or measure angles, significantly improving maintenance efficiency. The mounting structure includes a guide body that is pre-positioned relative to the valve.
Solution Approach 2:
The locking mechanism is designed to be self-aligning and self-securing. When the handle is rotated to a desired position, the locking member automatically engages with the corresponding locking feature on the guide body, providing positive mechanical feedback that confirms correct positioning. This self-service characteristic reduces the time and complexity of maintenance operations.

AI summary
A control assembly for a valve or any type of rotatable device can include a handle configured to rotate a valve member of the valve to control flow of fluid through the valve. The handle can include a locking member and a grip portion. The control assembly can include a guide body including a mounting surface, a central aperture, and a plurality of locking features. Each of the plurality of locking features can be spaced apart from a center of the central aperture by a first distance. Each of the plurality of locking features can be arranged to engage the locking member to releasably secure the handle at corresponding rotational orientations. Each rotational orientation can be associated with a corresponding flow configuration for the valve.
