Abstract: Fluid flow control apparatus for use with fluid valves are disclosed. An example apparatus disclosed herein includes a plug of a sliding stem fluid valve. The plug has a first portion slidably coupled to a second portion. The first portion includes a first bleed port. The second portion includes a second bleed port opposing the first bleed port. The second portion is to contact a seat of the fluid valve to close the fluid valve. The example apparatus further includes a cavity formed in an outer circumferential surface of the plug by the first portion and the second portion. An axial dimension of the cavity is to decrease when the first portion slides toward the second portion. The decrease is to radially outwardly displace a seal disposed in the cavity. The seal has a curved outer surface configured to engage an inner circumferential wall of a cage of the fluid valve in response to the second portion contacting the seat. The example apparatus further includes a pin disposed in the first bleed port and the second bleed port. The pin is to align the first portion and the second portion relative to a common longitudinal axis.

Abstract: Pistons are disclosed herein. An apparatus includes an actuator defining a first chamber; and a piston disposed in the first chamber, the piston including a second chamber and a seal groove in which a seal is disposed, the second chamber to receive fluid from the first chamber to enable a force imparted by the fluid within the second chamber to urge the seal into sealing engagement with a surface defining the first chamber.

Abstract: Pistons are disclosed herein. An example apparatus includes a piston defining a chamber and a circumferential groove in communication with the chamber. At least a portion of the chamber is to be substantially filled with a fluid. The example apparatus also includes a piston ring disposed in the chamber and the groove. The fluid is to apply a first pressure to the piston ring to enable the piston ring to apply a second pressure to a cylinder wall. The second pressure is to be greater than the first pressure.
Abstract translation: 活塞在这里公开。 示例性装置包括限定腔室的活塞和与腔室连通的周向凹槽。 腔室的至少一部分将基本上充满流体。 示例性装置还包括设置在腔室中的活塞环和凹槽。 流体是向活塞环施加第一压力，以使活塞环能够向缸壁施加第二压力。 第二压力应大于第一压力。

Abstract: Rotary shaft seals are disclosed herein. An example apparatus includes a valve body and a shaft extending into the valve body. The shaft is to rotate relative to the valve body. The example apparatus also includes a seal. The seal is disposed outside of the valve body and fixedly coupled to the valve body and the shaft to provide a fluid seal between the shaft and a cavity within the valve body.

Abstract: Methods and apparatus to load a valve packing are described. An example load apparatus to load a valve packing includes a guide including a flange and a wall protruding from the flange. The wall defines a cavity to receive a biasing element and a stop movable between a non-active state and an active state. The stop in the non-active state to enable movement of the guide in a first rectilinear direction relative to a longitudinal axis of a packing bore of a fluid valve and the stop in the active state to prevent movement of the guide in the first rectilinear direction. The stop to control an amount of deflection of the biasing element in the first rectilinear direction when the stop is in the active state.

Abstract: A piston actuator includes a transfer assembly and an actuator assembly connected to the transfer assembly. The actuator assembly has a cylinder assembly with a side wall and an end wall and defines a cavity. A piston assembly is disposed within the cavity and a screw guide assembly is secured to the end wall of the cylinder assembly such that the screw guide assembly is adjustable to limit the travel of the piston assembly.

Abstract: A process control apparatus includes a housing, a process control device disposed in the housing, and a temperature control device operably coupled to the housing for regulating a temperature of an atmosphere internal to the housing. The temperature control device includes a vortex tube and a flow control valve. The flow control valve is coupled to the vortex tube and includes a temperature sensing feature configured to sense a temperature of an atmosphere internal to the housing and configured to move a control element of the flow control valve based on the sensed temperature between a plurality of positions to selectively direct the flow of fluid from the first and second vortex outlets to the atmosphere internal to the housing.

Abstract: Apparatus are disclosed to bias a tube towards a seal. An example apparatus includes a pneumatic actuator having a diaphragm plate, a yoke housing, and a tube. The tube conveys pressurized fluid between the yoke housing and the diaphragm plate, wherein a first end of the tube extends through a first seal gland in the diaphragm plate to form a seal against an outer surface of the tube and a second end of the tube extends through a second seal gland in the yoke housing to form a seal against the outer surface of the tube. The first end of the tube has a first cross-sectional area that is greater than a second cross-sectional area of the second end of the tube to bias the tube toward the yoke housing during operation of the pneumatic actuator.
