유한요소법을 이용한 서지 릴리프 밸브의 디스크 시일 최적설계

The mega-projects that are Ocean plant, seawater desalination, nuclear power generation, etc are recently gaining the world's interest. The projects are certain to need surge relief valve that is one of the elements for the safety of the plant system. The surge relief valve is a safety device to protect surge pressure such as water hammer. Water Hammer is caused by sudden changes in flow. In recent years Pumping Systems have become large scale and surge relief valve have become large scale. disc seal that is important parts of surge relief valve have effect on quality. Disc seal with disc and disc seat are served as sealing function in the surge relief valve. The sealing force on the disc seal is analyzed by the FEM and design values are optimized by using the Taguchi method.
