Abstract：The pulse generation process of the rotary valve pulse generator used in pulsed extraction column was theoretically analyzed and studied. The theoretical model including the inflating and deflating through the rotary valve and the location variation of liquid surface due to the effect of pulsed gas in the pulse leg was derived. The experimental results of single phase flow, which is produced by the large-scale rotary valve pulse generator used in the no-plate extraction column with the inertial diameter of 0.3 m and height of 5.6 m, are in good agreement with those calculated by the theoretical model.
