Abstract:

The plug molded line equation plays an important part in the pressure drop of the control valve. Based on the finite element analysis software ANSYS, a control valve simulation model was established, the plugs with different molded lines were analyzed, and the effects of different molded lines on the pressure drop were presented. At the same time, the stress analysis of the control valve body was shown by considering the fluid-structure interaction. This study provides theoretical guidance for shortening the optimization design cycle of the control valve.

Key words: control valve; plug molded lines; ANSYS; fluid-structure interaction
