摘　　要：研制一种远程、先导式高压大流量减压阀;介绍了该减压阀特点,建立了减压阀数学模型,利用Matlab进行该减压阀动力学仿真,研究各个参数对减压阀性能的影响。根据仿真结果,加工了一台实物产品。搭建了减压阀性能测试试验台,分析了压力、流量特性,并和仿真做了比较。结果表明:仿真和试验符合的比较好,说明仿真对减压阀的研制与分析具有指导作用。该减压阀使用方便,安全、可靠,已经用于数个试验中。A new kind of remote and pilot-operated type high-pressure mass flow reducing valve was developed. The characteristics of this reducing valve are introduced. A mathematical model of the reducing valve was built. Dynamic simulation of the reducing valve was done with Matlab. The effect of each parameter on the reducing valve performance was studied. According to the simulation result, a real reducing valve was manufactured. A reducing valve capability test bed was built. The pressure and flux characteristic were analyzed and compared with the simulation. The result demonstrates that the test result is coincident with simulation results quite well, which indicates that the simulation has guiding function for development and analysis of the reducing valve. The reducing valve is easy to use, safe and credible. It has been employed in a number of tests.
