摘要： A valve trim assembly configured to be disposed in a fluid flow control valve, including, a valve seat adapted to be disposed in a fluid passageway of the fluid flow control valve. The valve seat includes an annular flange and a seating surface spaced from the annular flange. The valve trim assembly additionally includes a fluid control member movable relative to the valve seat to control fluid flow through the fluid passageway, wherein the fluid control member is movable from a closed position, in which the fluid control member sealingly engages the seating surface of the valve seat, and an open position, in which the fluid control member is spaced from the seating surface, by moving the fluid control member away from the annular flange of the valve seat.

摘要： Techniques for diagnosing failures in a digital solenoid I/P converter are provided herein. A controller of the I/P converter may apply a fixed voltage to an I/P coil of the I/P converter, causing an armature to move from an off-position to an on-position in a properly-functioning I/P converter. The controller may receive an indication of whether a digital logic line trip has occurred, indicating that a current for the I/P coil has reached a desired maximum current level. The controller may remove the fixed voltage applied to the I/P coil when the maximum current level is reached or when a threshold period of time has elapsed from the application of the fixed voltage to the I/P coil. The controller may diagnose, based on whether the digital logic line trip occurred prior to removing the fixed voltage, a failure in the I/P converter.

摘要： An example method to obtain process data associated with a process control system received from a field device includes identifying, at a computing device, associated data and a payload included in the data packet, the associated data including a source bit, determining, at the computing device, a type of connection between the field device and the computing device based on the source bit, determining, at the computing device, an encryption key identifier and an initialization vector based on an auxiliary data packet received prior to the data packet, generating, at the computing device, a nonce value based on the source bit and the initialization vector, the nonce value indicative of an input to a data encryption algorithm used by the field device to encrypt the payload, and extracting, at the computing device, the process data associated with the process control system from the payload.

摘要： The claimed method and system develops a useful lifetime profile for a component of a process control device, such as a valve, and uses that lifetime profile to determine a projected remaining lifetime for the device component in operation. The lifetime profile is developed from using real world operational data of similar process control devices, used under substantially the same operating conditions as to be experienced during operation. Profiles may be developed for numerous device components, from which a projected lifetime profile for the entire process control device is developed. Based on the projected remaining lifetime, notification warnings may be sent to remote computers and maintenance scheduling may be automatically achieved.

摘要： A fluid flow control device includes a valve body defining an inlet, an outlet, and a fluid flow path extending therebetween, a valve seat ring coupled to the body that defines an orifice through which the fluid flow path passes, a cage coupled to the body that defines an interior bore, a control element slidably disposed within the interior bore of the cage, and a particle catcher at least partially disposed within an interior bore of the control element. The particle catcher includes a particle catcher body that defines an inner flow path and at least one particle catcher passage through which the fluid flow path passes. An outer surface of the particle catcher and an inner surface of the control element form a particle catching portion. The at least one particle catcher passage directs the fluid flow path downwardly into the particle catching portion.

摘要： Methods and apparatus to adjust operation of a fluid flow control assembly are disclosed. An example safety valve controller apparatus includes comparator circuitry to compare a current measurement to at least one of a first threshold associated with a first flow setting of a fluid flow control assembly or a second threshold associated with a second flow setting of the fluid flow control assembly, and determine a first drive signal associated with the first flow setting or a second drive signal associated with the second flow setting in response to satisfying a respective one of the first or second thresholds, and current modulating circuitry to determine a third drive signal based on the current measurement, the third drive signal to modulate the flow setting of the fluid flow control assembly between the first and second flow settings.
