Design and Research of Pressure Regulating Valve for Large Flow Fuel System
The fuel pressure regulating valve is an important component of the ship power system,which is mainly used to stabilize the fuel pressure of the fuel supply system and reduce the impact of system pressure fluctuation on the gas turbine.Based on the characteristics of long voyage and large volume of modern ships,a pressure control valve suitable for large flow fuel system was designed,its working principle was analyzed,the fuel flow model in the control valve was studied,and the internal flow field was analyzed by numerical simulation.A test system based on the actual fuel supply system was built,and the system parameters under two different working conditions were tested.The results show that the structure of the designed fuel pressure control valve is reasonable,and the flow,pressure and response time of the system meet the requirements of gas turbine after using the valve.
