VORRICHTUNG UND VERFAHREN ZUR ABNÜTZUNGSÜBERWACHUNG IN AUFLAGEMATERIAL VON VENTILEN

摘要

Systems and methods are discussed that monitor wear in seat materials of a valve. One aspect of the present invention includes a system. The system includes sensors to sense the open/closed status of the valve within a desired range. The system also includes a set of counters to count each time the desired range is adjusted to characterize the valve as having the open/closed status if the valve was not within the desired range. The count of each counter is indicative of wear in seat materials of the valve. Another aspect of the present invention includes a method. The method includes determining an open/closed status of the valve within a desired range, and adjusting adaptively the desired range so as to characterize the valve as having the open/closed status if the valve was not within the desired range. Each iteration of adjusting is indicative of wear in seat materials of the valve.
