Abstract
A flow control assembly for subsea applications comprises a valve assembly and a damper assembly configured to control fluid flow between an external region and the valve assembly. The damper assembly comprises a damper housing, a damper flowpath extending between the inlet and the outlet of the damper housing, and a flow restrictor apparatus disposed in the damper flowpath to control a damper coefficient of the damper assembly.
Claims17
A flow control assembly for subsea applications, comprising:
- a valve comprising:
- a valve housing having a flowpath extending from an inlet to an outlet of the valve housing;
- a valve member movable between a first position and a second position in the flowpath;
- and
- a damper interface flowpath disposed in the valve housing;
- and
- a damper assembly configured to control fluid flow between an external region and the valve, the damper assembly comprising:
- a damper housing having an inlet in fluid communication with the damper interface flowpath of the valve housing and an outlet in fluid communication with the external region;
- a damper flowpath extending between the inlet and the outlet of the damper housing;
- and
- a flow restrictor apparatus disposed in the damper flowpath to control a damper coefficient of the damper assembly.

A flow control assembly for subsea applications, comprising:
- a valve housing having an inlet port and an outlet port forming a valve flowpath through the valve housing;
- a valve member movable within the valve flowpath between a first position and a second position;
- a valve biasing member configured to urge the valve member towards the first position;
- and
- a damper interface flowpath disposed in the valve housing;
- and
- a damper assembly comprising:
- a damper housing having an inlet in fluid communication with the damper interface flowpath and an outlet in fluid communication with an external region;
- a damper flowpath extending between the inlet and the outlet of the damper housing;
- and
- a damper valve assembly disposed in the damper housing and comprising:
- a first damper check valve having a first damper valve flowpath, wherein the first damper check valve is positionable between an outflow unchecked position and an inflow checked position;
- a second damper check valve having a second damper valve flowpath, wherein the second damper check valve is positionable between an outflow checked position and an inflow unchecked position, and wherein the damper flowpath includes the first damper valve flowpath and the second damper valve flowpath;
- and
- a flow restrictor apparatus disposed in the damper flowpath to control a damper coefficient of the damper assembly.
