1 球阀基础知识:
Basic knowledge of ball valves:

球阀即以球体作为启闭件的阀门。随着加工技术、检测技术与智能控制技术的突飞猛进，以及各种密封新材料的不断涌现，球阀产品将得到越来越广泛的应用。目前球阀产品在一般工业管道得到广泛应用。
We are 1 pc ball valve supplier, ball valve is a valve with sphere as opening and closing parts. With the rapid development of processing technology, detection technology and intelligent control technology, as well as the emergence of various new sealing materials, ball valve products will be more and more widely used. At present, ball valve products are widely used in general industrial pipelines.

早在19世纪80年代美国就开始设计球阀，但是当时缺乏适当的密封圈材料，限制了球阀产品的发展。直到本世纪50年代，聚四氟乙烯等弹性密封材料的出现以及机床工业的发展才使球阀产品的发展出现转机并得到飞速发展。
As early as the 1980s, the United States began to design ball valves, but the lack of appropriate sealing ring materials limited the development of ball valve products. Until the 1950s, the emergence of elastic sealing materials such as polytetrafluoroethylene and the development of machine tool industry made the development of ball valve products turn around and get rapid development.
