| Abstract: | A large flow lock valve is designed to meet the demands of pitch controllable adjusting and fixing for the pitch propeller which is used in a large flow controllable pitch propeller hydraulic system. The characteristics of the lock valve are analyzed in the virtual test system, including the working flow rate, the presetting lab of the poppet, the diameter and the mass of the control piston, and the open close characteristics of the lock valve which is affected by the fluid friction force, based on hydraulic simulation and virtual testing technology. The simulation results provide a guidance to the improvement and design of the large flow lock valve. |
