description: This work describes the system for afterburning hydrogen from radioactive process vents of a 1200 MW reactor plant (VVER-1200), the specifics of the operation of control valves in this system. A brief overview of the types of valves, the principles of its operation is given. The development of a control valve for the hydrogen afterburning system of radioactive process vents is underway. The calculation of the wall thicknesses of the weak parts of the body is carried out in accordance with PNAE G 7â002â86, based on this calculation, the valve is modeled in Solidworks CAD. A brief description of the finite element method, which is used in the modeling of physical processes and calculations in the Ansys software package, is given. Using the Ansys software package, the stress state of the valve is calculated, stress fields are calculated under various loading conditions, such as: initial tightening of the bonnet studs, design pressure of the medium (without initial tightening), change in temperature of the medium at a rate of 150â/hour, load from weight of the pipeline, the load from the weight of the pipeline during design earthquake. Based on these data, a verification calculation for static strength is carried out. A hydraulic calculation of the valve is given, as a result of which the distribution fields of the speed and pressure of the working medium in the flow part of the valve are given, and the throughput characteristic is constructed.
