다이어프램 구동형 글로브 밸브의 진단장비 개발

  • Published : 2007.09.01


Air-operated valve is one of principal valves that are used to control fluid flow in nuclear power plants. A periodic diagnosis for the safety of power plants is necessary. But there are many difficulties such as economic loss caused by income of high cost devices and a matter hard to deal with users. In this study, we developed the diagnostic system that users of power plants are easy to handle. The diagnostic system is composed of database module, diagnosis test module and analysis module.
