Henan Jinkong Tianqing Coal Chemical Industry obtained patent authorization for "a calibration device for a flow meter" and "a connection device for a flow regulating valve"

Thread Content

Recently, "a calibration device for flow meters" and "a connection device for flow regulating valves" independently developed by Henan Jinkong Tianqing Coal Chemical Co., Ltd. were officially approved* * The Intellectual Property Office reviewed and obtained utility model patent authorization. The acquisition of this patent is not only the result of Tianqing Company's innovative work practice concept of "from production to production", but also adds another "sharp tool" for efficient operation and maintenance of factory equipment. Jinkong Tianqing Company has always adhered to the purpose of serving production, taking innovation-driven development as its core, and carried out scientific and technological innovation management around solving problems in production system bottlenecks, energy conservation and consumption reduction, safety and environmental protection. The two patents approved this time are directed at problems that can be seen everywhere in chemical production sites - flowmeters are the core equipment for chemical production process control, and their accuracy is directly related to the stability of the production process. However, existing flow meter calibration devices mostly use flange connection, which makes disassembly and assembly before and after calibration cumbersome and inconvenient, seriously affecting calibration efficiency. ； At the same time, the flow regulating valve is a key device for controlling the flow of media. The conventional connection method is complex, time-consuming and labor-intensive, and cannot meet the needs of chemical production that requires frequent disassembly and installation. It not only increases operation and maintenance costs, but also restricts production progress. In response to these two major industry problems, the R&D team of Jinkong Tianqing Company is based on actual production and seeks breakthroughs from structural optimization and convenient use. To solve the problem of flow meter calibration, a support plate with a positioning rod is added to the rear end of the front pipeline to match the hydraulic cylinder and pressure block to quickly position and fix the flow meter to be calibrated. The rear pipeline is equipped with a movable plate and a telescopic bellows, which can be quickly connected and disassembled without a flange connection. It is equipped with a protective support plate to increase stability and protect equipment, successfully solving the problems of tedious disassembly and low efficiency of traditional flow meter calibration. ； In response to the problem of connecting the flow regulating valve, the R&D team designed an adaptable connection device. Support plates with positioning boxes are set at both ends of the pipeline. Together with a motor, an electric push rod and a rotatable pressure plate, the flow regulating valve can be quickly disassembled and assembled through precise positioning and rotation locking. At the same time, a protective cover and sealing structure are added. This device is not only easy to operate and has a stable connection, but also greatly reduces the labor intensity of maintenance personnel. The two patents approved this time are strong proof that the company focuses on the pain points on the front line of production and deepens the practice of innovation-driven development strategy. In the future, Jinkong Company will continue to focus on the real needs of the front line of production, promote the implementation of more practical and efficient innovation results, empower safe production, reduce costs and increase efficiency, and lay a solid foundation for high-quality development of the company.
