Modeling static and dynamic characteristics of pressure reducing valves

Abstract


The article deals with mathematic simulation of static and dynamic characteristics of a pressure reducing valve installed at the outlet of a noise suppression device. A mathematical model implemented in Matlab/Simulink softwar complex is developed. As a result of simulation dependences of the main operating parameters of a pressure control valve on the area of the orifice flow section are obtained.
