摘要： Process control instruments having local intrinsic safety barriers and methods of manufacturing the same are disclosed. An example field instrument for a process control assembly includes a non-protection compartment, intrinsically safe circuitry positioned in the non-protection compartment, a protection compartment, non-intrinsically safe circuitry positioned in the protection compartment, and local barrier circuitry positioned in the protection compartment to operatively couple the non-intrinsically safe circuitry to the intrinsically safe circuitry, the local barrier circuitry to prevent the intrinsically safe circuitry from receiving an electrical energy that is greater than an electrical energy threshold from the non-intrinsically safe circuitry.

摘要： Systems and techniques for accessing and controlling field devices to collect data and convert protocols are disclosed herein. An example system to access a field device includes one or more processors, a transmitter, a wireless network interface controller, and a memory storing instructions that, when executed, may cause the field communicator device to retrieve process parameter data encoded in a field device transmission protocol. The field communicator device may retrieve the process parameter data at a plurality of time intervals from a field device, and the process parameter data may correspond to a process parameter for the field device. The field communicator device may also store at least some of the process parameter data, analyze the process parameter data over the plurality of time intervals to identify a condition of the field device, and transmit an indication of the condition of the field device to a remote device.

摘要： A valve, such as a ball valve, can include a noise attenuation assembly to control fluid expansion through the valve and provide noise abatement. The valve can include a valve body and a valve stem and the noise attenuation assembly can include a flow control body and a trim body. The flow control body can be coupled to the valve stem and the flow control body can be configured to selectively permit fluid flow through the valve body in an axial direction. The trim body can include a plurality of channels to control fluid expansion during fluid flow through the valve body. The trim body can be engaged with the flow control body at first and second mounting structures of the flow control body to secure the trim within a fluid pathway of the flow control body.

摘要： Apparatus for noise reduction in valves are disclosed herein. An example valve disclosed herein includes a valve body defining a fluid passageway between an inlet and an outlet, a plug, and a cage in the fluid passageway. The plug is disposed in the cage. The plug is moveable in the cage to control fluid flow through the fluid passageway. The cage includes an inner wall having first openings, an outer wall having second openings, the outer wall disposed coaxially around the inner wall, and an insert having third openings. The insert is disposed between the inner wall and the outer wall.

摘要： A flow control device has a valve body having an inlet, an outlet, and a flow path connecting the inlet and the outlet and a unitary trim cartridge assembly secured to the valve body. The trim cartridge assembly has a cage disposed in the flow path, a bonnet coupled to the cage, and a retaining element disposed between the cage and the bonnet. The cage includes an exterior groove formed on an exterior surface of the cage, the bonnet includes an interior groove formed on an interior surface of the bonnet, and the retaining element extends into the interior groove and the exterior groove. A height of the interior groove and/or a height of the exterior groove is greater than a height of the retaining element to allow the cage to move longitudinally within the bonnet with the bonnet and cage assembled.

摘要： A flow control valve includes a valve body having a first section and a second section attached to the first section. A flow control member is positioned within the valve body and a shaft extends through the valve body and is connected to the flow control member to move the flow control member between an open position and a closed position. A sealing gasket is positioned within the valve body and engages the valve body to prevent the flow of fluid between the first section and the second section. The sealing gasket has an annular metallic body having an inner surface and an opposing outer surface, the outer surface defining a primary sealing surface, a groove formed in the outer surface, and an insert positioned within the groove, the insert defining a secondary sealing surface.
