Study on Chain Relationship between Condenser and Vacuum Isolation Valve

In the condenser unilateral isolation conditions,the corresponding vacuum isolation valve should be shut down at the same time,and in any case,it is not recommended to open the valve,otherwise some consequences would occur,such as the increasing of non-condensable gas of the condenser,and degrading of vacuum pump performance and condenser performance.This paper makes a comparison of unilateral isolated condition and the normal operation condition,and analyzes the condenser leakage,non-condensing gas accumulation trends,vacuum pump performance,and the performance of the condenser.
