Abstract: Mathematical models of pipe rupture valve in hydraulic elevator systems are established, the valve’s flow cut-off performance and step response characteristics in hydraulic elevator systems are analyzed on the simulink environment of matlab kits. A comprehensively experiment research is carried out using analogous test rig and hydraulic elevator experiment rig, the numerical simulations coincide with experiment results in general. The theory and experiment references are provided for designing pipe rupture valve.

Key words: Flow cut off, Hydraulic elevator, Pipe rupture valve
