Description

Technical Field

[0001] The invention relates to the field of valves, and in particular to a dual-drive control valve. Background Art

[0002] Process gases used in SEMI, LCD, LED, and SOLAR industrial processes produce byproducts after the process is completed. These pollutants can cause vacuum pump failures and shutdowns. In particular, Furness equipment for the Diff process uses a large-capacity dome-shaped chamber for the process, so when a large amount of process gas is input, process byproducts are also produced. The DRY Pump that maintains the byproduct discharge and vacuum is faced with unpredictable shutdowns, resulting in large wafer contamination and huge cost losses.

[0003] The dual-valve system is used for control switching. When a vacuum pump fails or stops production, another spare vacuum pump can be used to avoid shutdown. However, after closing one of the valves in this dual-valve system, the by-product pollutant gas will no longer enter the failed vacuum pump through the valve, but the by-product pollutant gas will still flow into the closed valve body, causing corrosion damage to the valve body structure.

[0004] Therefore, in view of the situation that when one of the valves in the above-mentioned dual-valve system is closed when the vacuum pump fails, by-product pollutant gas may still enter the valve body and accumulate for a long time, causing structural corrosion damage. A dual-drive control valve can be designed to prevent pollutant gas from flowing into the valve and causing accumulation after one of the valves is closed. Summary of the invention
