Benefits of technology

The present invention is a shutoff valve device that can be used to control fluid flow in a production string. The device includes a body, a flow tube, a bi-directional actuator, and a flapper valve. The flow tube is capable of axial movement within the body's borehole and is dragged back and forth by the actuator to open or close the valve. The valve is hingedly coupled to the bottom sub and can be fully opened or closed. The device allows for easy control of fluid flow in the production string.

Abstract

A shutoff valve device for permitting and preventing fluid flow in a production string. In one embodiments, the shutoff valve device comprising: a body comprising a borehole, wherein the body is a top sub coupled to a bottom sub via a threaded fastener; a flow tube disposed within the body's borehole and capable of axial movement within the body's borehole, comprising a flow tube borehole; a bi-directional actuator attached to a bottom opening of the flow tube, comprising flexible flaps; and a flapper valve disposed within the body's borehole, wherein the flapper valve is hingedly coupled to a top surface of the bottom sub and capable of moving between a fully opened and fully closed position.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a non-provisional application that claims the benefit of U.S. Application Ser.
