Abstract
This cryogenic miniature globe valve is used to transfer the liquified natural gas which temperature is $-169^{\circ}C$, supplied pressure is 30bar(3.0MPa). In the present work the temperature distribution and thermal deformation is calculated numerical the FE method is useful to predict the thermal matter of cryogenic miniature globe valve. For this reason, to optimum design of the cryogenic miniature globe valve the analysis of the parameter about bonnet has been studied. It's used 3-D modeling to analyze cryogenic globe valve, which is 1/2". Numerical study used 3-D modeling makes a decision of efficient process of product before producing in the factory. A commercial software(ANSYS 10.0) is used in the structural analysis for cryogenic globe valve.
