Valve models should normally be expressedGate Valves valve type, drive type, connection type, structural features, sealing surface material, body material and the nominal pressure and other factors. Standardization of the valve Globe Valves type of valve design, use, sale offer convenience. Valve types and materials of today are more and more valves for the model even more complex. Although the valve of China unified standard Plug Valves for the model, but increasingly unable to meet the needs of industrial development in the valve. At present, the valve manufacturer generally uniform numbering; who can not adopt a unified code of the method, the factory Junan their need for numbering. Play a role on the industry Web site, industry Balance Valves information to inform the work of "Valve models methodology" used for industrial pipe valve, throttle valve, ballAPI Cast Steel Valves valve, butterfly valve, diaphragm valve, plunger valve, plug valve, check valve, safety valve, reducing valve, steam trap. It includes the preparation of the valve and valve type naming.

译文：阀门的型号编制方法以及知识介绍
阀门型号通常应表示出深井泵阀门类型、驱动方式、连接形式、结构特点、密封面材料、阀体离心泵材料和公称压力等要素。阀门型号的标准化对阀门的设计、选用、销售提供了方便。当今阀门的类型和材料越来越多，阀门的型号编制也愈来愈复杂。我国虽有阀门型号编制的统一标准，但愈来愈不能适应阀门工业发展的需要。目前，阀门管道泵制造厂一般采用统一编号方法；凡不能采用统一编号的方法，各制造厂均按自己的螺杆泵需要制订编号方法。关于发挥行业网站作用、推进行业信息隔膜泵工作的通知　《阀门型号编制方法》适用于工业管道用闸阀、节流阀、球阀、蝶阀、隔磁力泵膜阀、柱塞阀、旋塞阀、止回阀、安全阀、减压阀、疏水阀。它包括阀门的型号编制和阀门的命名。
