Vacuum Gate Valve with Light-Transmission Plate for Optical Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum gate valves in existing systems hinder visual inspection of apparatuses on the opposite side when closed and limit optical system alignment in a vacuum environment.
Innovation Solution
A vacuum gate valve with a light-transmission plate installed on the blocking plate, allowing visual inspection and optical system alignment in a vacuum state by transmitting light through the closed valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blocking plate is used to close the fluid passage in a vacuum gate valve, then the valve sealing performance is improved, but the ability to visually check apparatuses on the opposite side deteriorates
Solution Approach 1:
The blocking plate is segmented by introducing a through-hole, dividing it into regions that can accommodate different functional elements (light transmission components, inspection components) while maintaining the overall sealing function of the valve body
Solution Approach 2:
A light transmission plate is introduced as an intermediary component installed on the blocking plate. This plate allows light to pass through the closed valve, enabling visual inspection of apparatuses on the opposite side without compromising the valve's sealing performance
