Apparatus, systems and methods for a flow control device

摘要

A flow control device for control of fluid flow through a tubular member comprises a control chamber having a piston disposed therein, where the piston is moveable from an open piston position to a closed piston position by the application of a first fluid pressure, and a valve chamber having a valve therein, where the valve is moveable from a closed valve position to an open valve position by the application of a second fluid pressure. A seal preventing fluid flow through the control chamber into the tubular member is formed in the closed piston position, and a flow path through the valve chamber and into the tubular member is formed in the open valve position.

1. A flow control device comprising:
a tubular member having an interior passageway for conveying fluids; a housing disposed about the tubular member and forming a chamber between the housing and the tubular member, wherein the housing is divided into a control chamber and a valve chamber; a piston disposed within the control chamber and moveable between a first piston position and a second piston position that is displaced from the first piston position, wherein
the piston divides the control chamber into first and second portions, andthe piston is moveable between the first piston position and the second piston position by the application of pressure on at least one face of the piston in fluid communication with the interior passageway; and a valve disposed within the valve chamber and moveable between a first valve position and a second valve position that is displaced from the first valve position, wherein the valve provides for selective fluid communication between a first portion of the valve chamber and a second portion of the valve chamber, wherein the piston provides a first flow path between the control chamber and interior passageway of the tubular member in the first piston position, and wherein the valve provides a second flow path between the valve chamber and interior passageway of the tubular member in the second valve position.
