Dynamic response analysis of high speed locking valve

A high speed locking valve with the characteristics of fast response,high pressure,large flux and no leakage was introduced.The valve was composed of a pilot valve and a main valve.Firstly,the mathematical model of the high speed locking valve was established and analyzed in linearization.Secondly,using computer simulation tool Matlab,its step response of the process based on above model was analyzed.The simulation result shows that the locking valve has favorable dynamic characteristics and its response time is only 9 ms.The curves of experiments and simulation results are quite close to each other,which indicates that the locking valve responses rapidly.
