【Ten Years of Rapid Development in Chemical Processing Equipment】Wear- and corrosion-resistant high-frequency tight-shut ball valves, 1996–2023
Thread Content
Ten years of rapid development in chemical processing equipment – praising the prosperity and strength of modern China. This is just a starting point; more participation from everyone will make things even more lively. Haichuan becomes even better with your involvement; we welcome everyone to join in the forum discussions. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* On May 5, 2023, the regional science and technology awards ceremony was held in Yinchuan, where achievements in scientific and technological innovation from 2021 were recognized and rewarded. A total of 5 such achievements received the first prize for scientific and technological progress. Wu Zhong Instrument Co., Ltd.’s project on independent innovation and industrialization of key technologies and equipment for wear-resistant, corrosion-resistant high-frequency tight-shut ball valves won the first prize for scientific and technological progress in the autonomous region for the year 2021.
“The project on independent innovation and industrialization of key technologies and equipment for wear-resistant, corrosion-resistant high-frequency tight-shut ball valves was carried out by Wuzhong Instrument Co., Ltd. with the support of the Ningxia Intelligent Control Valve Engineering Technology Research Center. Ball valves that are wear-resistant, corrosion-resistant and capable of high-frequency tight shutting were developed for use in facilities such as coal chemical industry, metallurgy, and petroleum refining. This project overcame the problems associated with high-frequency operation of ball valves under conditions of high temperature, high pressure, severe corrosion, and intense erosion, such as erosion, wear, sticking, seizure, and sealing leaks, thereby ensuring the safe, stable, and efficient operation of process facilities over extended periods of time. Through independent innovation, the project developed various design elements such as a seat sealing structure for high-frequency, tight-shutting ball valves that are resistant to wear and corrosion ； By overcoming challenges such as the casting process for large, thick-walled valve bodies involving pouring from the bottom of the mold, the process of metallurgical bonding between the alloy ceramic coating on the ball core and the substrate to achieve hardening, the ultra-precision machining of the high-hardness ball core surface along with online inspection technologies, as well as life-test simulations under high pressure differences, key manufacturing equipment for casting, machining, and inspection was developed ； It solved the problem of plant shutdowns and damage caused by frequent failures of high-end control valves under complex and harsh operating conditions, playing an important role in the development of automatic control technology in China’s process industry. All products of the project have been industrialized, with 16 authorized patents obtained, yielding significant economic and social benefits.
