Abstract
An assembly and method for a choke valve body having a choke valve to control flow of fluids. A sleeve positioned in and attached to the choke valve body to flow the fluids through an inner sleeve region internal to the sleeve instead of an outer sleeve region external to the sleeve.
Claims20
A choke valve assembly comprising:
- an inlet body configured to receive fluids flowed through an upstream flow line;
- an outlet body fluidically coupled to the inlet body, the outlet body configured to discharge fluids received at the inlet body out of the choke valve assembly into a downstream flow line;
- a choke valve body positioned between and attached to each of the inlet body and the outlet body, the choke valve body comprising a choke valve configured to be opened or closed to control flow of the fluids from the inlet body to the outlet body;
- and
- a sleeve positioned in an inner region defined by the choke valve body, wherein the sleeve is attached to the choke valve body via a seal and does not contact the choke valve body, the sleeve defining an inner sleeve region internal to the sleeve and an outer sleeve region comprising a volume external to the sleeve in the inner region defined by the choke valve body, the sleeve configured to flow the fluids from the inlet body through the inner sleeve region instead of through the outer sleeve region, wherein the outer sleeve region shares a longitudinal axis with the inner sleeve region.

A method comprising:
- receiving, from an upstream flow line, fluids at an inlet body of a choke valve assembly;
- flowing the fluids from the inlet body through a choke valve body to an outlet body of the choke valve assembly, wherein a sleeve is positioned in the choke valve body positioned between the inlet body and the outlet body, wherein the sleeve is attached to the choke valve body via a seal and does not contact the choke valve body, wherein the sleeve defines an inner region internal to the sleeve and an outer region as a volume external to the sleeve and internal to the choke valve body, the outer region sharing a longitudinal axis with the inner region, the choke valve body comprising a choke valve configured to be open or closed to control flow of the fluids from the inlet body to the outlet body, and wherein flowing comprises flowing, by the sleeve and in response to the choke valve being open, the fluids received at the inlet body to the outlet body through the inner region instead of through the outer region;
- and
- discharging the fluids from the outlet body to a downstream flow line.

A hydrocarbon flow line assembly comprising:
- an upstream flow line configured to flow well fluids comprising hydrocarbons extracted from a hydrocarbon reservoir in a subterranean zone;
- a choke valve assembly downstream of the upstream flow line, the choke valve assembly fluidically coupled to an outlet of the upstream flow line to receive the well fluids from the upstream flow line, the choke valve assembly comprising a sleeve positioned in an inner region of the choke valve assembly, the sleeve defining an inner sleeve region internal to the sleeve and an outer sleeve region comprising a space, the outer sleeve region external to the sleeve in the inner region of the choke valve assembly, wherein the sleeve is attached to a choke valve body of the choke valve assembly via a seal and does not contact the choke valve body, the sleeve configured to flow the well fluids through the inner sleeve region instead of through the outer sleeve region, wherein the outer sleeve region shares a longitudinal axis with the inner sleeve region;
- and
- a downstream flow line downstream of the choke valve assembly and configured to receive the well fluids from the choke valve assembly.
