Valve packing installation apparatus and related methods for use with fluid valves are disclosed. An apparatus includes a tube to receive a stack of packing components. The tube has a first end and a second end. A plunger is disposed within the tube adjacent the second end. The plunger is slidable toward the first end to expel the stack of packing components into a valve in a predetermined order associated with an installation sequence.

Methods, apparatus, systems, and articles of manufacture of valve packing apparatus and related methods. An apparatus includes a cartridge including packing components and a spring. The cartridge is dimensioned to fit in a bore of a bonnet of a valve. A retainer is disposed in an aperture of the cartridge. The retainer is removable from the aperture to release the spring to apply a predetermined compressive load to the stack of packing components.

A fluid end block for a reciprocating pump defines a fluid chamber and a packing bore. An outlet fluid passage is formed in the fluid end block in communication with the fluid chamber and includes an outlet valve. An inlet fluid passage is formed in the fluid end block in fluid communication with the fluid chamber and includes an inlet valve. A plunger is reciprocally disposed in the packing bore. Packing in the packing bore is positioned to contact the plunger and a packing sleeve is disposed between the packing and the packing bore. The packing sleeve is a hollow cylinder with inner and outer surfaces and an inner end configured to be inserted into the packing bore. The inner end includes a bevel extending between the outer surface and the inner end, the outer surface including a notch formed therein adjacent the inner end.

A progressive sealing system for a reciprocating machine includes a pressure breaker having a first seal, and one or more additional seals between the pressure breaker and an end plate. One or more seal housings hold the seals between the first seal and the end plate. The end plate couples the progressive sealing system to a housing of a cylinder of the reciprocating machine such that a surface of the first seal faces a chamber of the cylinder. A housing for the second one of the seals includes a bore having an inner surface. The inner surface of the bore of the second seal housing and an outer surface of a rod of the reciprocating machine define an annular space when the rod is received in the bore. The packing case includes an expansion chamber adjoining the annular space.

An improved bearing or bushing body extraction from a stuffing box using jack screws is provided. The bearing or bushing seal body includes at least one jack screw on each half of a split body. The jack screw passes axially through the sidewall of the body to the inner flange of the stuffing box and turning the jack screw against the inner flange to lift the body from the stuffing box. A single inner threaded or double threaded insert with a reverse outer thread and standard inner thread is inserted into the bottom wall of the body so that the body may be installed flush against the inner flange. By turning the jack screw through the insert and against the flange, the seal body is pushed out rather than pulled.
