Abstract
An one-piece integrated coke drum de-heading seat machined from a single forced metal block. The seat has bias members and expansion chambers stacked and aligned to increase the load force from about 250 PSI to over 850 PSI when activated by gasses.
Claims6
A valve seat comprising:
- a wall with an inward facing surface facing a flow way, the inward facing surface comprising a plurality of interior expansion chambers formed in the inward facing surface wherein the interior expansion chambers are configured to axially expand when pressure from coking process flowing through the flow way builds in the flow way;
- an outward facing surface facing a steam chamber, the outward facing surface comprising a plurality of exterior expansion chambers formed in the outward facing surface wherein the exterior expansion chambers are configured to axially expand as steam pressure builds in the steam chamber;
- and
- wherein the interior expansion chambers are configured to be activated independently of the exterior expansion chamber.
1 more element
A valve seat comprising:
- a wall dividing an exterior steam chamber and an interior flow way wherein the wall facing the steam chamber comprises a plurality of exterior expansion chambers and the wall facing the interior flow way comprises a plurality of interior expansion chambers wherein the exterior expansion chambers and the interior expansion chambers are configured to be activated by steam independently of the exterior expansion chamber that are configured to be activated by process pressure;
- and
- wherein the expansion chambers are stacked so as to substantially overlap and configured to complimentary create an axially expanding force.
