description: This work provides a description of control valves, their types and main differences. The description of cage valves is given. The technical characteristics and operating parameters of the valve designed by RES Engineering LLC for installation on the pipeline of the cooling system of the QKC ventilation system of the UBA power supply building of Kursk NPP-2 are given. The work also describes the design of the valve, typical cage and plug profiles. In the course of the work, modified models of the cage and plug are being developed. For numerical simulation a mathematical model is described, the conditions for the calculation are given, and the geometry of the reinforcement is finalized in accordance with the standards. In order to refine the grid resolution, a grid convergence analysis is performed. For each cage option, an Ansys Fluent calculation is performed to obtain a flow characteristic. The optimal cage profile is selected and the calculation is carried out for a valve with a modified plug. To confirm the possibility of operation of the valve with a modified flow part a calculation is carried out, during which the permissible differential is determined, the excess of which causes the cavitation process. Based on the calculation, a graph of the dependence of the cavitation coefficient on the stroke of the stem is designed.
