Abstract
A fluid flow inhibitor for use with increased fluid flow. The fluid flow inhibitor has a fluid tubular which contains a chamber with at least one fluid plug and at least one fluid barrier with an aperture or orifice. When increased fluid flows through the system, the fluid plug or plugs move to block the flow of fluid through the orifice(s) or aperture(s) thereby reducing or eliminating fluid flowing through the system. When the fluid flow rate returns to normal flow rate, the fluid plug(s) resume their standby position and fluid flows through the orifice or aperture at a normal rate.
Claims25
An apparatus for impeding the flow of fluid through a body comprising:
- a fluid barrier having at least one orifice therethrough;
- a hollow body having a maximum predetermined fluid flow through rate;
- the hollow body having an interior and an exterior surface with the fluid barrier disposed about the interior surface,
- at least one fluid plug;
- wherein the hollow body contains the at least one fluid plug positioned in the interior of the hollow body;
- whereby when a fluid of a specified viscosity and specific gravity is flowing through the hollow body exceeding the predetermined flow rate, said at least fluid plug is moved and wedged into said at least one orifice in said fluid barrier thereby impeding the flow of the fluid through the body.
A method for impeding the flow of fluid through a tubular comprising;
- moving a fluid through a body, wherein
- the body contains an interior and an exterior;
- at least one fluid plug in the interior of the body;
- and the body contains a fluid barrier with an orifice disposed about the interior circumference of the interior,
- whereby when the fluid is moving through the body at a flow rate in excess of a predetermined flow rate, the at least one fluid plug is moved and wedged into the fluid barrier orifice disposed about the interior surface thereby impeding the flow of the fluid through the body.
