Through the study of the stability mechanism of fluid induced vibration of the regulator valve, a new idea can be provided for the vibration reduction of the regulator valve, that is, to avoid the negative damping effect of the system, and consume the energy generated by the vibration through the positive damping of the system itself, so as to prevent the vibration from continuing to expand. This method has a distinct theoretical guidance for the vibration prevention and vibration reduction.On the basis of the relationship between static fluid force and opening and pressure difference, the vibration displacement of valve core and the relationship between dynamic fluid unbalance force and opening and pressure difference under different opening and pressure difference are analyzed.The results show that the larger the opening and the smaller the pressure difference, the smaller the spool displacement and the smaller the fluid unbalance force. By comparing the simulation analysis results of the two models, it can be seen that the nonlinear model is more consistent with the actual vibration of the valve core, so the nonlinear model is more accurate for the design of the regulating valve.The temperature field in the valve refers to the general name of the temperature distribution at each position in the valve at each time. The temperature field is divided into two kinds, one is the stable state temperature field, the temperature everywhere remains constant, this temperature field is called the steady state temperature field. The other is the temperature field under changing working conditions, the temperature distribution changes with time, and this temperature field is called the unsteady temperature field. The steady-state temperature field is studied in this chapter. When the heat generated in the valve is equal to the heat lost, the temperature field in the valve reaches the steady-state.
