AI Technical Summary

Technical Problem

Safety valves are prone to jamming and failure due to the strong adhesion of process media. Existing methods of periodic shutdown and maintenance affect production efficiency, while lack of maintenance poses an explosion risk, making it difficult to balance safety and efficiency.

Method used

Using wireless communication technology, the system monitors the valve core friction signal and valve stem displacement of the safety valve in real time through acoustic emission sensors. Combined with the LoRa+BLE dual-mode communication module, it transmits data, assesses risks using a medium viscosity-sticking risk model, automatically generates cleaning work orders, and performs customized cleaning. It also detects internal leaks in real time to ensure thorough and effective cleaning.

Benefits of technology

It enables intelligent monitoring of the operating status of safety valves, timely identification of failure signs, reduction of unnecessary downtime maintenance, improvement of production efficiency, reduction of explosion risk, and ensures the reliability of safety valves and cleaning effect.

Abstract

This invention discloses an intelligent monitoring method for the operating status of a safety valve based on wireless communication, belonging to the field of mechanical condition detection. This method includes the following steps: capturing friction signals generated by residual process media in the safety valve core in real time using an acoustic emission sensor, while simultaneously collecting millimeter-level displacement changes of the safety valve stem and dynamic valve inlet pressure; generating data every N seconds. Compared with existing technologies, the advantages of this invention are: by collecting the operating data of the safety valve, this invention specifically analyzes the friction signals generated by residual process media (such as syrup / fermentation broth). The data packet transmission strategy is primarily event-triggered, supplemented by timed reporting, ensuring that when the safety valve operates abnormally, the risk can be assessed promptly using a medium viscosity-sticking risk model, and analysis results can be obtained, without the need for periodic safety valve inspections that affect production efficiency, as required by existing technologies.
