Angle Valve Handwheel Securing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner valves with handwheels suffer from unintentional separation from the valve housing, especially in tight spaces, leading to difficulties in removal or reinstallation, as the handwheel can be accidentally pushed away during valve plunger movement.
Innovation Solution
A valve design featuring a securing element that can be moved from a release position to a securing position, preventing unintentional separation by engaging with the valve housing, ensuring conscious manipulation is required for separation, and incorporating a groove and stop mechanism to secure the actuator element, allowing only rotational movement while preventing longitudinal displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the handwheel is mounted on the valve housing without a securing element, then the device complexity is reduced and ease of manufacture is improved, but the handwheel can be accidentally separated from the valve housing during operation
Solution Approach 1:
The securing element is designed as a separate, movable component that can be independently actuated. This segmentation allows the securing function to be added without complicating the overall structure, as the securing element operates independently from the handwheel and valve body.
Solution Approach 2:
The securing element acts as an intermediary component between the handwheel and the valve housing. It provides a controlled connection mechanism that prevents accidental separation while allowing intentional removal, thus improving reliability without significantly increasing complexity.
2Reliability
If a securing element is added to prevent handwheel separation, then the handwheel attachment reliability is improved, but the device complexity increases
Solution Approach 1:
The securing element is designed to be self-securing through its movable nature. When engaged, it automatically secures the handwheel without requiring additional fastening operations or complex locking mechanisms, thus improving reliability with minimal added complexity.
Solution Approach 2:
The securing element changes the state of connection between the handwheel and valve housing from permanently fixed to controllably secured. By changing the parameter of connection stability from static to dynamically controllable, reliability is improved while keeping the structural addition minimal.
3Reliability
If the handwheel is securely fixed to the valve housing, then the handwheel attachment reliability is improved, but the ease of operation for removal and reinstallation deteriorates
Solution Approach 1:
The securing element transforms the static connection between handwheel and valve housing into a dynamic, controllable connection. The movable securing element allows the connection state to be changed from secured to released on demand, making removal and reinstallation easy while maintaining security during normal operation.
Solution Approach 2:
The securing element is designed to be预先 positioned and easily actuated. Before removal is needed, the securing element is already in place to prevent accidental separation. When removal is intended, the preliminary positioning of the securing element allows for quick and easy disengagement without requiring complex removal procedures.
