Integrated Ball Valve Gear Ring for Compact Core Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of the electric ball valve structure due to the separation of the transmission mechanism and valve core by the valve body, which also requires a valve cover to limit the up-and-down displacement of the valve core ball, complicates the design and functionality.
Innovation Solution
A compact ball valve design integrating a drive mechanism, a transmission mechanism, and a valve body assembly, where the transmission mechanism includes a first gear ring and the valve core is partially connected to or positioned with the gear ring, eliminating the need for a separate valve cover by directly contacting the gear ring with the valve core component, thus simplifying the structure and reducing parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmission mechanism and valve core are separated by the valve body, then the valve core can be independently positioned, but the structure becomes more complex and requires additional valve cover components
Solution Approach 1:
The patent merges the transmission mechanism and valve core into a single integrated assembly where the valve core component directly engages with the gear ring. The valve core component includes a platform part that abuts against the gear ring, eliminating the need for separate positioning mechanisms and valve covers, thus reducing structural complexity while maintaining reliable positioning
2Reliability
If a valve cover is added to limit the up-and-down displacement of the valve core ball, then the valve core positioning is improved, but the number of parts and assembly complexity increases
Solution Approach 1:
The valve core component is designed as an integrated structure that combines the valve core ball, platform part, and positioning features into a single component. The platform part directly abuts against the gear ring to limit displacement, eliminating the need for separate valve covers and reducing the total number of parts
Solution Approach 2:
The valve core component serves multiple functions simultaneously: it controls fluid flow through the valve core ball, limits up-and-down displacement through the platform part abutting the gear ring, and provides rotational engagement. This multi-functionality eliminates the need for separate valve cover components
3Force
If the transmission mechanism directly contacts the valve core component, then the driving force required is reduced, but the structure becomes more compact and requires precise positioning
Solution Approach 1:
The transmission mechanism is directly integrated with the valve core component, with the gear ring abutting against the platform part of the valve core component. This direct contact eliminates intermediate transmission elements, reducing the driving force required while the precise geometric features built into the integrated structure ensure accurate positioning
