A packer valve for regulating the fluid flow rate and pressure within a fluid conduit such as a well, includes a housing, and an inflatable packer element mounted on an elongated mandrel. The inside diameter of the housing is formed with an arrangement of annular grooves which circumscribe the inflatable packer element. The inflatable packer element is adapted to adjust an annulus between the housing and the inflatable packer element to provide complete shutoff of fluid flow or to provide a tortuous flow path for fluid flow within the annulus. The tortuo...
A packer valve for controlling a fluid flow rate in a conduit, comprising: a housing formed with an inside diameter and adapted to be placed within the conduit in fluid communication therewith; and an inflatable packer element mounted within the housing and adapted to be inflated to vary the annular area between the inside diameter of the housing and the outside diameter of the packer, thereby providing a flow path between the housing and inflatable packer element for regulating a fluid flow rate and pressure within the conduit.
