| Abstract: | In order to improve operation characteristics of control system for high-pressure feed-and back-water circulation so as to achieve energy-saving purpose,a self-driven multifunctional circumference valve has been developed.Integrating 4 control functions such as the flux induction,backflow prevention,by-pass control and multi-stage pressure reduction,the valve makes previously complicated by-pass system reasonably simplified and the jump adjustment gentled,which helps to keep normal operation of relevant pum... |
