At 5:30 pm on October 22, Xinhai Night University started on time at the conference and event center. After Xinhai News was broadcast, Huang Zhenqiang, the deputy general manager, brought the course of "Knowledge, Structure, Principle and Maintenance of Common Valves".

   Mr. Huang started from the basic knowledge of valves, introduced valve classification, main parts and materials in detail, and taught the valve characteristics, classification, and working principles of valves such as gate valves, valve bodies and bonnets, ball valves, check valves, and safety valves. The courses are highly specialized and rich in theoretical knowledge, which brings a high-quality course that lays a solid foundation and strong quality for employees.

   Through this course, I hope that the majority of employees will consolidate the basic knowledge structure, understand the principle of equipment, improve professional standards, and learn and accept new knowledge with a guilty mindset, adding glory to Xinhai's high-quality development.
