Benefits of technology
The patent describes a device called a barrier that can be used to control drilling operations in downhole operations. The barrier has a housing, a valve, and a flow tube that rotates independently of other components. This allows for smooth drilling without causing any rotational input to other components of the barrier. The technical effect of this device is that it provides better control and reliability during drilling operations, and reduces the risk of damage to the wellbore.
Problems solved by technology
In industries where barriers are common and sometimes where other tools are rotated while passing through barriers, such as in downhole industries, there is potential for damage to barriers that then would require repair or replacement at not inconsiderable expense.

embodiment 1
[0021] A barrier comprising: a housing; valve member disposed in the housing; a flow tube within the housing; and an actuator disposed in the housing and in operable communication with the flow tube, the flow tube configured to rotate within other components of the barrier without imparting rotational torque to the actuator or the other components.
embodiment 2
[0022] The barrier of embodiment 1 further comprising an actuator coupling operatively connected to the flow tube through a bearing or bushing so that the flow tube is rotationally independent of the actuator coupling.
embodiment 3
[0023] The barrier of embodiment 2 wherein the actuator coupling is operatively connected to the actuator.

Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. provisional application No. 62 / 143,906, filed Apr. 7, 2015, the entire contents of which are incorporated herein by reference.BACKGROUND[0002]In industries where barriers are common and sometimes where other tools are rotated while passing through barriers, such as in downhole industries, there is potential for damage to barriers that then would require repair or replacement at not inconsiderable expense. In view hereof, the relevant arts would be receptive to alternative configurations that reduce or eliminate damage to barriers while rotating other tools therethrough.BRIEF DESCRIPTION[0003]A barrier includes a housing; valve member disposed in the housing; a flow tube within the housing; and an actuator disposed in the housing and in operable communication with the flow tube, the flow tube configured to rotate within other components of the barrier without imparting rotational torque to the actua...
