Title:
DEVICE AND SYSTEM FOR PREDICTING FAILURES OF ACTUATED VALVES
Document Type and Number:
WIPO Patent Application WO/2013/183059
Kind Code:
A8
Abstract:
The invention relates to a system for determining a potential future failure of an actuated valve controlling fluid flow in a line by causing an angular change between two states of a stem of said valve, which comprises: (a) a sensor for, upon receipt a control command at said actuator, continuously sensing the angular position of the stem, and conveying to a monitoring unit a respective angular variation signal; and (b) a monitoring unit which comprises: (bl) a sampling unit for receiving said angular variation signal, and producing a transition vector which comprises periodical samples from said signal; (b2) a local storage for storing nominal transitional values for said actuator- valve pair; and (b3) a local comparator unit for comparing at least a portion of said transitional vector with the corresponding stored nominal transitional values, and if a difference above one or more predefined threshold values is determined, issuing an alert for a potential failure of said actuator.
