摘要: TFW型调压阀是水电站中用来替代调压井的一种调压设备，在水电站运行过程中不可避免会遇到机组突甩负荷的情况，导致管道中压力升高，此时即通过调压阀对管道进行泄压，所以整个引水系统的压力调控效果将由调压阀的性能决定。本文借助CFX、Workbench等软件，基于流固耦合理论，建立了调压阀阀盘与流体的流固耦合计算模型并进行了流固耦合分析。经过数值计算得出阀盘的应力与变形随开度变化的分布规律，从而为调压阀的安装、维护及运行提供依据。
Abstract: TFW pressure regulating valve is a pressure regulating device used to replace the pressure regu-lating well in the hydropower station. During the operation of the hydropower station, it is that the unit will suffer sudden load rejection. As a result, the pressure in the pipeline will increase. At this time, pressure regulating valve will be used to relieve the pressure in the pipeline. Therefore, the effect of the pressure regulation in water diversion system will be determined by the performance of the the pressure regulating valve. Based on the fluid-solid coupling theory, this paper establishes the fluid-structure coupled calculation model of pressure regulator valve disc and fluid and analyzes the fluid-structure interaction by using CFX, Workbench and other software. After the numerical calculation, the distribution law of the stress and deformation of the valve disc changes with the opening degree are obtained, which provides the basis for the installation, maintenance and operation of the pressure regulating valve.
