Abstract
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.
Claims20
An apparatus to install a valve packing comprising:
- a cartridge including packing components and a spring, the cartridge dimensioned to fit in a bore of a bonnet of a valve;
- and
- a retainer disposed in an aperture of the cartridge to prevent the spring from applying a compressive load to the packing components, the retainer, when removed from the aperture, to release the spring to apply a predetermined compressive load to the packing components.
An apparatus to install a valve packing, comprising:
- a cylindrical tube having a first end and a second end, the tube having an outer surface dimensioned to fit within a bore of a valve;
- a biasing member disposed within the tube at the first end of the tube;
- packing components disposed within the tube adjacent the biasing member;
- and
- a retainer to hold the biasing member in a compressed state to prevent the biasing member from contacting the packing components, wherein the retainer is to be moved to enable the biasing member to apply a load to the packing components after the cylindrical tube has been inserted into the bore of the valve.
An apparatus to install a valve packing comprising:
- means for applying a predetermined compressive load to packing components;
- and
- means for retaining the means for applying the predetermined compressive load.
