Abstract
Fluid flow control devices and related systems and methods may include a body or housing and a plug at least partially positioned in the body or housing to define a flow path. In a position of the plug, the plug and the body or housing may collectively define a fluid flow path.
Claims20
A fluid flow control device, comprising:
- a body defining at least one fluid inlet, at least one fluid outlet, and a portion of a fluid flow channel connecting the at least one fluid inlet and the at least one fluid outlet;
- and
- a plug positioned at least partially within the body and defining at least one aperture through the plug, the at least one aperture of the plug defining another portion of the fluid flow channel, wherein:
- in a first position of the plug, the at least one aperture is configured to be aligned with the fluid flow channel to define an at least partially tortuous path between the at least one fluid inlet and the at least one fluid outlet;
- and
- in a second position of the plug, the at least one aperture is configured to at least partially block the fluid flow channel to at least partially inhibit fluid flow along the fluid flow channel.

A fluid flow control system, comprising:
- a fluid inlet;
- a fluid outlet;
- and
- a valve having a fluid flow control device positioned between the fluid inlet and the fluid outlet, the fluid flow control device defining a fluid pathway between the fluid inlet and the fluid outlet, the fluid flow control device comprising:
- a housing having at least one connecting passageway defined in the housing;
- and
- a plug positioned at least partially within the housing, wherein:
- in a first position of the plug, one or more openings in the plug and the at least one connecting passageway in the housing are configured to define the fluid pathway having three or more stages between the fluid inlet and the fluid outlet;
- and
- in a second position of the plug, the plug is configured to at least partially inhibit fluid flow along the fluid pathway between the fluid inlet and the fluid outlet.
7 more elements
A method of reducing a pressure in a fluid with a fluid flow control device, the method comprising:
- positioning a plug in a housing in a first closed position to at least partially inhibit fluid flow through the fluid flow control device;
- and
- positioning the plug in the housing in a second open position to enable the fluid flow through the fluid flow control device, comprising:
- directing the fluid flow through an inlet in the fluid flow control device;
- directing the fluid flow through an aperture in the plug;
- altering direction of the fluid flow;
- and
- directing the fluid flow through an outlet in the fluid flow control device.
