FIELD: machine building.
SUBSTANCE: method for preventing hydrodynamic disturbance at operation of filling control valve involves the change of operating mode of shutoff device of control filling valve by short-term stops of movement of gate valve of filling valve at opening and closing. Frequency of stops at the beginning of opening period is higher than that at the end of opening period, and frequency of stops at the beginning of closing period is lower than that at the end of closing period.
EFFECT: improving operating reliability of pipelines of filling systems by reducing the intensity of pressure pulses or hydraulic impacts occurring at the changes of filling efficiency.
