Abstract

The high temperature flow-rate control valve is a key component to control the flow rate of fuel supply for scramjet engines. In this paper, a bellow-type flow rate control valve for high temperature working fuel is developed. The construction and working principle of the valve are introduced and the mathematical models of the valve are established. The dynamic characteristics of displacement are simulated by using Matlab/Simulink platform and experimented simultaneously. By comparing the simulation and experiment results, the dynamic response characteristics of flow rate can be studied, so the working reliability of the valve can be guaranteed. As a result, the flow rate of the valve can be controlled accurately according to the needs of fuel supply for scramjet engine.
一种高温流量控制阀动态特性研究
高温流量控制阀是控制超燃冲压发动机供油流量的关键部件。本文研制了一种适用于高温工作燃料的波纹管式流量控制阀。介绍了该阀的结构和工作原理,建立了该阀的数学模型。利用Matlab/Simulink平台对位移的动态特性进行了仿真,并进行了实验。通过仿真与实验结果的对比,研究了流量的动态响应特性,保证了阀门的工作可靠性。从而可以根据超燃冲压发动机供油的需要精确控制气门的流量。
