Abstract
A seat pocket insert for a valve block may include an insert body extending, in an axial length, between a first end surface and a second end surface. Additionally, the second end surface may have a profile configured to sealingly engage with a seat of a valve. Further, a bore may be provided axially extending through the first end surface to the second end surface of the insert body.
Claims24
A method comprising:
- disposing a first seat in a flow bore of a valve block;
- inserting a first seat pocket insert into an outlet or an inlet of the flow bore, wherein the first seat pocket insert comprises;
- an insert body extending, in an axial length, between a first end surface and a second end surface, the insert body comprising:
- an inner diameter defining a bore extending axially through the insert body along the axial length of the insert body;
- an axial protrusion, comprising:
- the second end surface at an end of the axial protrusion, and
- a protrusion inner surface defining a protrusion inner diameter greater than the inner diameter of the bore;
- and
- a seat pocket having a profile defined by the protrusion inner surface and a protrusion shoulder surface;
- aligning the first end surface to be flush with an outer surface of the valve block;
- and
- using a pressure from a valve to sealingly engage the first seat against the profile of the seat pocket and abut the second end surface of the axial protrusion against a shoulder of the first seat.
