摘要： An apparatus for overriding a valve actuator to move a valve stem to a second position includes an override body with a central axis. A piston is located within the override body. A bushing is non-rotatably carried within the override body. An override shaft is in threaded engagement with the bushing and extends through a sealed orifice in the override body. Fluid pressure applied to the piston causes the bushing to engage the valve actuator and push the valve stem, and alternatively, rotation applied to the override shaft causes the bushing to move linearly to engage the valve actuator and push the valve stem.

摘要： A system for securing a valve actuator to body of a valve assembly includes an actuator housing having housing lugs protruding radially to define a plurality of housing slots therebetween. A bonnet has bonnet lugs protruding radially to define a plurality of bonnet slots therebetween. Each of the housing lugs are sized to pass axially through a respective one of the bonnet slots when the actuator housing is in a released position and, after passing through the bonnet slots, the actuator housing is rotatable to a locked position where at least a portion of one or more of the housing lugs is axially aligned with a portion of a respective bonnet lug to prevent axial movement of the actuator housing, the actuator housing rotating less than one full revolution between the released and locked positions. A securing mechanism prevents relative rotation between the actuator housing and the bonnet.

摘要： A system for securing a valve actuator to a valve assembly includes an actuator housing with a plurality of housing lugs protruding radially. A cylinder assembly is located within the actuator housing and has a horseshoe connector to engage a valve stem nub of a valve stem and transfer axial movement of the horseshoe connector to axial movement of the valve stem. A bonnet has a plurality of bonnet lugs protruding radially from the bonnet to define a plurality of bonnet slots therebetween, wherein each of the plurality of housing lugs are sized to pass axially through a respective one of the plurality of bonnet slots when the actuator housing is in a released position, the actuator housing being rotatable to a locked position such that the plurality of bonnet lugs prevent axial movement of the actuator housing in at least one direction.

摘要： A locking apparatus for attaching to an end of a valve actuator includes an assembly body, the assembly body releasably securable to a valve actuator. The assembly body has a stem bore for receiving an actuator stem, and a plunger orifice through a sidewall of the assembly body. An immobilizer assembly has a plunger extending through the plunger orifice, and biased radially outward and moveable between a radially inner position where the immobilizer assembly extends over the stem bore, and a radially outer position where an inner end of the immobilizer assembly is radially outward of the stem bore. A segmented housing circumscribes the assembly body and is moveable between a first position where the plunger is in the radially outer position and a second position where the plunger is in the radially inner position. A fusible band selectively retains the segmented housing in engagement with the immobilizer assembly.

摘要： A gate valve includes a valve body with a How passage intersected by a gate cavity. The gate valve also includes, a gate with an axis, a downstream gate face, and an upstream gate face on an opposite side. The gate is axially movable in the gate cavity between a gate closed position and a gate open position. A seat ring is located between each gate face and the valve body, at the intersection of the flow passage and the gate cavity. An annular seal is located between each of the seat rings and the valve body. At least one annular filter is located between at least one of the seat rings and the valve body, each of the at least one filters being located radially inward from one of the seals relative to an axis of the flow passage.

摘要： A bonnet assembly for assisting to move a valve stem to a retracted position includes a bonnet body. The bonnet body has a bonnet valve end selectively connected to a valve, a bonnet actuator end opposite the bonnet valve end selectively connected to a valve actuator. A valve stem extends through the central bore of the bonnet body. A booster piston seal circumscribes the valve stem and engages an inner diameter of the central bore. The booster piston seal selectively defines an extent of a pressure cavity containing pressure media. An effective stem pressure surface faces in a direction towards the valve and is in fluid communication with the valve when the bonnet body is connected to the valve. A booster pressure surface faces in a direction towards the valve when the bonnet body is connected to the valve and is selectively acted on by the pressure media.

摘要： Embodiments of the present disclosure include a valve assembly including a supply housing with a first bore and an injectable housing coupled to the supply housing with a second bore. The valve assembly further includes a piston extending through at least a portion of the first and second bores, the piston being reciprocable axially along a longitudinal axis. The valve assembly also includes a first inlet at a first end of the supply housing for directing a working fluid toward a first end of the piston. The valve assembly includes a second inlet extending through the injectable housing toward a cavity that receives an injectable material. The valve assembly also includes a second outlet at a second end of the injectable housing that directs the injectable material out of the injectable housing as the piston moves axially along the longitudinal axis.

摘要： Embodiments of the present disclosure include a method of replacing valve operation methods during fracturing operations including installing a first operator on a first valve of a first fracturing tree. The method also includes installing a second operator on a second valve of a second fracturing tree, the second fracturing tree being adjacent the first fracturing tree. The method also includes removing the first operator from the first valve, the first valve maintaining a position on the first fracturing tree after the first operator is removed. The method further includes removing the second operator from the second valve, the second valve maintaining a position on the second fracturing tree after the second operator is removed. The method also includes installing the first operator on the second valve after the first operator is removed from the first valve and after the second operator is removed from the second valve.
