Abstract
The stress and deformation behavior of an alarm valve has been analyzed using a finite element method. The strength safety of an alarm valve is calculated for the given maximum test pressure of 2.0MPa. The FEM computed maximum stress of an alarm valve is only 6.1% of yield strength, 370MPa and 4.6% of tensile strength, 485MPa, which are occurred at the corner part between a cover flange and a valve body. And the maximum deformation of $12{\mu}m$ was developed at the middle part of an alarm valve. These results mean that a typical alarm valve was designed with a excessively high strength safety, which may lead to an increase of a weight and a dimension.
