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.
Claims19
A valve seat comprising:
- a plurality of alternating expansion chambers and bias members configured to bias a valve seat to expand axially,
- wherein the bias members comprise a portion of the inner diameter of the seat;
- wherein the bias members are configured to exert an axial force;
- wherein the expansion chambers and bias members are stacked so as to substantially overlap and configured to complimentary create the axially expanding force;
- and
- wherein the walls of the expansion chambers are configured to selectively expand the axial dimensions of the seat when activated with a gas to compliment the axial force created by the bias members.

A valve seat comprising:
- a plurality of biased members configured to bias the seat to expand axially so that the seat is compressed prior to insertion into a valve, and upon placement in the valve axially expands and is secured in position against a gate and a retainer by the force of the bias.
A valve seat comprising:
- a system of alternating expansion chambers and bias members configured to bias the seat to expand axially,
- wherein the bias members comprise a portion of the inner diameter of the seat;
- wherein the bias members are configured to exert an axial force;
- wherein the expansion chambers and bias members are stacked so as to substantially overlap and configured to complimentary create the axially expanding force;
- wherein the walls of the expansion chambers form a portion of the interior wall of the seat and wherein the chambers are configured to selectively expand the axial dimensions of the seat when activated with a gas to compliment the axial force created by the bias members;
- wherein at least one expansion chamber comprises a steam chamber formed between a plurality of bias members wherein the steam chamber is isolated from the inner diameter of the seat.
