Computerized Information System for Safety Valve Calibration
Each model of safety valve test bench can be optionally equipped with an information-based computer system for safety valve calibration.
Features and Benefits
- It can automatically generate inspection work orders, ledgers (safety valve summary tables), reports, and records, and supports printing.
- It can automatically generate safety valve tag parameters, reducing the risk of re‑entry errors and supporting automatic continuous tag printing.
- The graph curve displays the adjustment process, the digital pressure reading, and automatically captures the opening pressure.
- It can automatically determine whether a safety valve is compliant in accordance with the “Safety Technical Supervision Regulations for Safety Valves.”
- Supports remote import of safety valve information, automatic calculation of sealing pressure, remote approval, and electronic signatures.
- Automatic reminders for expiring safety valves; enables the aggregation and export of expired safety valve data.
- Supports power‑off verification of safety valves and, upon power restoration, independently manages safety valve information.
