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.
