Gate Valve Actuator Bracket for Adjustable Stroke Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gate valve systems with actuators lack a secure and efficient mechanism to adjust the position of the valve handle, leading to potential misalignment and reduced operational reliability.
Innovation Solution
The proposed gate valve and actuator system incorporates a securement mechanism with slots of varying lengths in the second bracket, allowing for adjustable securement of the connecting member and handle, ensuring precise alignment and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed securement mechanism is used for the valve handle, then the structure is simple, but the adaptability to different stroke lengths is poor
Solution Approach 1:
The securement mechanism transitions from a fixed position to an adjustable position along the slot, allowing the bracket to adapt to different valve handle stroke lengths while maintaining a relatively simple overall structure. The slot provides a guided range of motion without requiring complex mechanisms.
Solution Approach 2:
The bracket with slot design serves multiple functions: it secures the valve handle, accommodates different stroke lengths, and provides a mounting interface for the actuator. This multi-functional design improves adaptability without proportionally increasing complexity.
2Reliability
If the valve handle position is not precisely adjusted, then the structure is simpler, but the operational reliability is reduced
Solution Approach 1:
The invention replaces complex mechanical adjustment mechanisms with a simpler slot-based positioning system. The slot geometry itself provides the alignment and securement function, eliminating the need for additional adjustment mechanisms while maintaining operational reliability.
3Adaptability or versatility
If multiple adjustment positions are provided for the valve handle, then the flexibility is improved, but the device complexity increases
Solution Approach 1:
The bracket is segmented into functional zones through the slot design, creating multiple potential securement positions along the slot length. This segmentation provides flexibility without requiring separate components for each position, as the continuous slot allows selection of appropriate positions based on specific application requirements.

AI summary
A gate valve and actuator for selectively opening and closing the gate valve. The gate valve has a housing having a passageway therethrough, a valve member moveable in the housing to selectively open and close the gate valve, and a connecting member connected to the valve member. The actuator has a linear actuator having a housing, a shaft selectively extendable from and retractable into the housing, a motor, and a bracket for connecting the linear actuator to the valve member. The bracket has a first pair of opposed slots having a length, and a second pair of opposed slots having a length greater than the length of the first pair of opposed slots. A securement mechanism selectively secures the connecting member between either the first pair of opposed slots or the second pair of opposed slots.
