METHOD OF OPERATING AND OPERATION SYSTEM FOR CONSUMPTION REGULATION VALVE Russian patent published in 2012 - IPC G05D7/06 

FIELD: operation of gas and liquid consumption regulation valve.

SUBSTANCE: method of operation of the consumption regulation valve determines the current valve openness, pressure difference and valve new opening rate on the basis of the valve Cv curve, set consumption value, current openness of the valve, and the valve pressure difference; the above valve pressure difference includes computation of the pressure difference by means of the valve Cv curve, current valve openness and shifted consumption; the operating system of the consumption regulation valve comprises a controller for defining a valve new opening rate on the basis of the valve Cv curve, preset consumption value, current openness of the valve and the valve pressure difference; besides the operating system additionally contains a meter for measuring consumption; the controller is executed to compute the above pressure difference through the valve Cv curve, current valve openness and measured consumption.

EFFECT: enhancement of the consumption control performed by the regulating valve.
