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.
Claims20
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;
- 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 a region external to the damper housing;
- 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 disposed between a first damper valve inlet and a first damper valve outlet;
- a first damper valve member, a first damper biasing member retainer, and a first damper biasing member disposed in the first damper valve flowpath biasing the first damper valve member into a checked position;
- and
- a second damper check valve having:
- a second damper valve flowpath disposed between a second damper valve inlet and a second damper valve outlet;
- a second damper valve member, a second damper biasing member retainer, and a second damper biasing member disposed in the second damper valve flowpath biasing the second damper valve member into a checked position.

- and
- a damper valve assembly disposed in the damper housing and comprising:
- a first damper check valve configured to allow fluid flow through the damper valve assembly in one direction and restrict fluid flow through the damper valve assembly in an opposite direction;
- and
- a second damper check valve configured to allow fluid flow through the damper valve assembly in one direction and restrict fluid flow through the damper valve assembly in an opposite direction,
- wherein the one direction that the second damper check valve allows fluid flow is opposite the one direction that the first damper check valve allows fluid flow.
