Structure and Fluid Dynamic Characteristics Analysis of Enclosed Nuclear Electric Valve

Abstract:

The electric valve, cutting off or connecting pipeline of nuclear equipment, is an essential component of nuclear facilities for safe operation. The structure of self-developed enclosed nuclear electric valve is introduced in the paper firstly, and dynamics analysis of steam fluid in valve is carried out to tackle typical problems including leakage in the rapid open-close process of valve for high-temperature and high-pressure steam fluid. It can be determined that dynamic characteristic of steam fluid will directly affect force suffered by valve in the rapid open-close process, greatly influencing movement and ultimate position accuracy of valve gate.
