二维插装式流量调节阀的理论分析和实验研究
Theoretical analysis and experimental study of two-dimensional cartridge flow control valve
摘要
Abstract
A novel two-dimensional cartridge flow control valve is proposed to address the problems of low power-to-weight ratio and large size of flow valves.The torque motor at the back of the valve body drives a two-dimensional piston with two degrees of freedom and amplifies the power to drive the spool movement,and the differential pressure feed-back lever on the valve body can accurately measure the inlet and outlet pressure difference without installing addi-tional pressure sensors.In this paper,the mathematical model of the valve is firstly established,and the stability analysis is carried out by using Matlab.Then the model is built by using AMESim,and the dynamic and static characteristics are simulated and analyzed.Finally,it is verified by experiment.This valve have a hysteresis loop of 4.4%,linearity of 1.6%,response time of about 44 ms,amplitude frequency width of about 17 Hz,phase fre-quency width of about 28 Hz,and the pressure difference measurement range is 8 MPa.Both theoretical analysis and experimental results show that two-dimensional cartridge flow control valve is a suitable solution not only for its simple structure and high work-to-weight ratio,but also for its good dynamic and static characteristics.关键词
