Modelling and Simulation of Pressure Limiting Valve Based on Input and Output Data
Journal Title: RECENT - Year 2014, Vol 15, Issue 42
Abstract
The article presents an original mathematic model of a direct drive pressure limiting valve, establishing the status of each variable as input or output data, respectively, underling the two stages of the valve: before and after opening. It is deduced time and complex mathematical model, and transient behaviour of the valve is analysed after the numeric simulation done in Simulink-Matlab. There are considered the two stages of the valve, before and after opening, highlighting their different frequencies and different upstream pressure and piloting pressure of the spool.
