Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum valves require complex control mechanisms to achieve high switching frequencies between suction and discharge, limiting their efficiency in applications requiring rapid changes.
Innovation Solution
A vacuum valve design utilizing rotatable control disks to alternately open and close flow paths, allowing for simple control of high switching frequencies between vacuum and ambient pressure, enabling rapid switching between suction and discharge.

If complex valve control is used to achieve high switching frequencies, then switching frequency is improved, but device complexity increases
Solution Approach 1:
The valve body is segmented into multiple flow paths (first flow path and second flow path) that can be independently controlled. Each flow path has its own control disk (first control disk and second control disk) that can be rotated to open or close the respective flow path, enabling high-frequency switching through distributed control rather than a single complex control mechanism
Solution Approach 2:
The control disks are designed to be rotatable, providing dynamic control of the flow paths. By rotating the control disks, the flow paths can be quickly opened or closed, enabling high switching frequencies. The dynamic rotational movement allows for rapid state changes without complex control mechanisms

AI summary
The vacuum valve (1) has a housing (2) that is provided with two connection ports (3,4). A primary flow path is formed between primary connection port and secondary connection port. A secondary flow path is formed between the housing opening (5) and the secondary connection port. The flow paths are set with the control discs respectively. The control discs are controlled such that the flow paths are alternately opened and closed.
