APPARATUS FOR PIPELINE INSPECTION AND METHOD OF ASSEMBLY
First Claim
1. An in-line inspection tool for pipeline inspection, the tool comprising:
- a channel through which pipeline fluid can flow through the tool;
a flow control valve assembly comprising a valve member which is movable between a closed position and an open position for controlling the rate of flow of pipeline fluid through the channel, the flow control valve assembly further comprising a fluid-filled chamber; and
an electrical linear actuator assembly configured to control movement of the valve member from the closed position to the open position, wherein the electrical linear actuator assembly is located in the chamber of the flow control valve assembly, wherein the electrical linear actuator assembly comprises a motor configured to operate the valve member, and wherein the electrical linear actuator assembly defines a flow path to allow fluid from the chamber of the flow control valve assembly to flow through the motor.
