Monitoring system for actuator devices in fluid pipelines
The granted patent US12072041B2 describes a sophisticated monitoring system designed for on/off actuator devices that control valves in fluid pipelines. This system is engineered to facilitate the movement of a valve member between two distinct positions: a normal operating condition (open) and an emergency condition (closed). Central to the system is an actuator device that utilizes at least one fluid cylinder to drive a linear actuator rod. The monitoring system incorporates a variety of sensors, including pressure, temperature, linear position, and deformation sensors, which collectively monitor critical operating parameters of the actuator. An electronic processing and control unit is responsible for activating the actuator to perform micro-movements of the valve member, detecting sensor signals during these movements, and estimating the actuator's capability to generate sufficient torque or force for complete valve operation.
Additionally, the monitoring system is designed to automatically assess the actuator's performance immediately after the micro-movement, ensuring that any anomalies can be detected in real-time. The system can identify specific components that may be causing performance issues, such as a lower-than-expected torque output. It also includes provisions for remote monitoring and control, allowing for communication between the actuator and a control station via wired or wireless connections. This capability enables the system to manage multiple actuator devices simultaneously, enhancing operational efficiency and safety in fluid pipeline management. Overall, the patent outlines a comprehensive approach to monitoring and controlling valve actuators, ensuring reliable operation in both normal and emergency conditions.
