Abstract
Description
Technical Field
[0001] This utility model belongs to the field of safety valve calibration and testing technology, specifically relating to a digital intelligent monitoring system for safety valves. Background Technology
[0002] Special equipment is a crucial foundation for building a modern industrial system. With socio-economic development, my country's special equipment is trending towards larger sizes, higher parameters, and higher risks. It is characterized by its large quantity, wide application, long supply chain, numerous responsible parties, and lengthy regulatory chains, making its safety a serious concern. Safety valves, as essential safety accessories for pressure-bearing special equipment such as boilers, pressure vessels, and pressure pipelines, are widely used in various industries including power generation, oil and gas, refining, chemicals, steel, papermaking, and pharmaceuticals. They are not only subject to mandatory annual inspections by the government but also serve as the last line of defense against overpressure for pressure-bearing equipment.
[0003] However, the current management and supervision model for safety valves has many prominent problems. First, information traceability is difficult. Safety valve supervision relies on manual paper records or simple electronic ledgers, which are prone to data errors, omissions, and tampering, making it difficult to trace information throughout the entire life cycle. Moreover, the relationship between safety valves and their respective special equipment is unclear. Second, the authenticity of verification data is insufficient. Data during the safety valve verification process is mostly entered manually, posing a risk of human intervention and affecting the accuracy of equipment safety assessments. Third, supervision efficiency is low. Regulatory departments need to grasp the status of safety valves through on-site inspections and review of paper reports, making it difficult to monitor the verification progress in real time, resulting in risks of overdue inspections and delayed early warnings. Fourth, enterprise management is extensive. Users rely on manual records for daily inspections and maintenance of safety valves, lacking digital tools, and the ledgers are not updated in a timely manner, easily leading to missed inspections and neglected maintenance.
[0004] Chinese patent CN208520570U discloses an online calibration interface device and an online testing system for safety valves. The online calibration interface device includes an isolation valve, a three-way valve, and a pressure tapping pipe. The isolation valve is located between the safety valve and the protective container. Two ports of the three-way valve are connected to the safety valve and the isolation valve, respectively, and the other port is connected to the pressure tapping pipe. The pressure tapping port of the pressure tapping pipe is connected to the calibration interface, so that the calibration interface is located in a position convenient for operators to operate. This patent addresses the risks of high-altitude operations and disassembly / reassembly issues during safety valve calibration, focusing only on the operational convenience of the safety valve calibration process. It does not cover the recording and associated management of information throughout the entire lifecycle of the safety valve, from manufacturing, installation, daily use to disposal.
