The valve safety interlock control system for the petrochemical industry, by integrating IoT, intelligent sensing, and remote-control technologies, enables a one‑click remote self‑diagnosis function, thereby significantly enhancing the intrinsic safety of the process unit.
The valve safety interlock control system for the petrochemical industry integrates IoT, smart sensing, and remote-control technologies to enable one‑click remote self‑diagnostics, significantly enhancing the intrinsic safety of plant operations. Centered on intelligent electric valves and equipped with high‑precision sensors, the system continuously collects real‑time data on valve position, torque, leak‑prevention alerts, and other parameters, transmitting this information via a 5G private network or industrial Ethernet to a cloud‑based platform in the central control room. Operators can remotely initiate the self‑check procedure through the monitoring interface; the system automatically performs valve opening/closing tests, sealing‑integrity assessments, and actuator‑status diagnostics, with all process data fed back to the monitoring terminal in real time.
The system incorporates built-in interlock logic: when it detects valve sticking, seal failure, or actuator malfunction, it immediately triggers multi-level alarms and automatically activates the emergency response plan—such as closing upstream and downstream valves, starting backup equipment, or initiating an interlocked shutdown—to prevent hazardous conditions from escalating at their source. Leveraging digital twin technology, the system can analyze historical valve operating data, predict seal‑wear trends, and schedule maintenance in advance, thereby minimizing unplanned outages.
This solution leverages a digital closed-loop comprising “perception–transmission–decision–execution” to reduce the frequency of manual inspections by 80%, boost fault‑identification accuracy to 99.5%, and minimize personnel exposure in high‑risk areas. It establishes a safety defense system for petrochemical facilities that combines proactive prevention with rapid response, driving the industry toward intelligent operations and intrinsic safety.
