Research on Large Steam Butterfly Valve for Steam Turbine DFMEA Tool System Based on Knowledge Management

Failure Modes and Effects Analysis (FMEA) method has been used to study the reliability of many different power generation systems, making it easier to take actions to overcome such issues, thus enhancing the reliability through design. A FMEA Knowledge Base System was designed and realized in this paper, and this system was used to design new steam butterfly valve for steam turbine. Through the system designer will improve product quality, and reduce risk.
