In this paper, base on the operating principle of water press pull-up inlet valve, we model the mathematical model of inlet-valve and made a simulation on computer.By the method of simulation, get the curve of control pressure (up cavity pressure) and opening force in process of pull-up inlet valve opening.Changing the structural parameter of inlet valve and working pressure of water press, gain the relationship between pull-up inlet valve opening force changing tendency and the structural parameter of inlet valve and working pressure.
