Design-Analysis and Optimization of Cryogenic Gate Valve

Abstract

The project include Design-Analysis and Optimization of the cryogenic gate valve. Cryogenic gate valve is the component used in low temperature application like trans- fer of Nitrogen, Hydrogen and Oxygen. The detail design of the cryogenic gate valve is studied thoroughly with the help of manuals of the valves of the company. In this project detail design of cryogenic gate valve components namely stem, wedge and body is carried out which meets the design requirements stipulated by various relevant standards. Assembly model of the gate valve and detail drawing of the com- ponents has been created using PRO/E software. Analysis (Thermal/Structural) is carried out for stem, body and wedge in ANSYS workbench and the stress values are compared with acceptance criteria. Design Optimization of the stem has been carried out to reduce the stresses generated in the stem.
