METHOD FOR CALIBRATING INDEPENDENT METERING VALVES
A method for calibrating a valve (26, 28, 30, 32) having a valve element (26a, 28a, 30a, 32a) movable between a flow blocking position and a flow passing position includes pressurizing fluid directed to the valve, increasing a current directed to the valve for controlling a position of the valve ele...

| description | A method for calibrating a valve (26, 28, 30, 32) having a valve element (26a, 28a, 30a, 32a) movable between a flow blocking position and a flow passing position includes pressurizing fluid directed to the valve, increasing a current directed to the valve for controlling a position of the valve element, and sensing a pressure of the fluid. The method for calibrating the valve also includes determining if a time-derivative of the sensed fluid pressure is greater than a predetermined threshold over a predetermined period of time, and determining a cracking point current command directed to the valve. The cracking point current command is directed to the valve when the time-derivative of the sensed fluid pressure is greater than the predetermined threshold.
L'invention concerne un procédé de calibrage d'une soupape (26, 28, 30, 32) ayant un élément de soupape (26a, 28a, 30a, 32a) mobile entre une position de blocage d'écoulement et une position de passage d'écoulement, comprenant la pressurisation du fluide dirigé à la soupape, l'augmentation d'un courant dirigé à la soupape pour commander une position de l'élément de soupape, et la détection d'une pression du fluide. Le procédé de calibrage de la soupape comprend également la détermination du fait de savoir si une dérivée en temps de la pression de fluide détectée est plus importante ou non qu'un seuil prédéterminé au cours d'une période prédéterminée de temps, et la détermination d'une commande en courant de point de fissuration donnée à la soupape. La commande en courant de point de fissuration est donnée à la soupape lorsque la dérivée en temps de la pression de fluide détectée est plus importante que le seuil prédéterminé. |
