    Abstract:

    Due to the lack of high dynamic flow measurement methods,it is difficult to directly measure the flow of pilot stage.A dynamic flowmeter with flow-displacement conversion function was designed,and the flowmeter was applied to the pilot stage of the displacement-flow feedback type proportional direction valve to measure and control the flow of the pilot valve,and form a proportional direction flow valve with pilot flow amplification.The simulation model of the proportional directional flow valve with pilot flow amplification was built in SimulationX,and the dynamic and static characteristics of the valve were studied.The results show that the valve has good static control precision and can accurately control the output flow;the larger the pressure difference between the inlet and outlet of the main valve is,the faster the dynamic response of the spool is;the load change will cause the flow overshoot,but the adjustment time is short.
