摘要： An intelligent actuator for a control valve includes an actuator body, an actuator rod, a biasing device, a controller, and at least one sensor. The actuator body includes an actuator casing defining a cavity. The actuator rod is adapted to be coupled to a control element of a control valve. The biasing device is disposed in the cavity of the actuator housing and operably coupled to the actuator rod for biasing the actuator rod into a predetermined position. The controller is carried by the actuator body and includes a memory, a processor, and logic stored on the memory. The at least one sensor is operably coupled to the controller for measuring various parameters of the actuator and transmitting those parameters to the controller. The at least one sensor can include one or more vibration sensors, one or more acoustic sensors, one or more temperature sensors, etc.

摘要： Methods and apparatus for acoustic fluid valve calibration are disclosed herein. An example method involves rotating a closure member of a valve to a involves rotating a closure member of a valve to a plurality of positions along a valve stroke, obtaining acoustic emission signals generated by a fluid passing through the valve using a sensor when the closure member is in the positions, and identifying, using a processor, a zero position of the closure member based on the acoustic emission signals.

摘要： Methods and apparatus for estimating a condition of a seal of a rotary valve are disclosed. An example method includes determining a seal wearing cycle of a flow control member of a rotary valve. The seal wearing cycle includes movement of the flow control member between a first position in contact with a seal and a second position. The example method further includes determining a torque of an actuator operating the flow control member for the seal wearing cycle and estimating a condition of the seal based on the torque.

摘要： Methods and apparatus for estimating useful life of a seal in a process control device are disclosed. An example method includes establishing a plurality of travel ranges of a stem or shaft of a process control device. Each travel range corresponds to different values corresponding to stresses experienced by the seal of the process control device during an operational cycle. The example further includes determining a count of operational cycles associated with each of the travel ranges and estimating a total amount of useful life of the seal consumed based on the counts.

摘要： A system and apparatus for detecting and monitoring cavitation inside a flow control device (10), such as a control valve, includes an acoustic emission sensor (26) coupled to the flow control device in a manner to acquire acoustic signals caused by cavitation. A processor (40) receives acoustic information from the acoustic emission sensor. The processor selectively identifies cavitation events from the acoustic information that meet certain predefined criteria. Cavitation levels are monitored based on at least one of a rate of cavitation events and intensity of individual cavitation events. The cavitation levels may be used to identify the presence of cavitation in the flow control device, to track accumulated cavitation in the flow control device, and/or to identify significant changes in the cavitation levels over time. This information may be used to reduce cavitation, estimate repair and maintenance, and/or monitor performance of the flow control device.
