在小编日常接到的词盘中，经常会碰到这样一种情况，客户只说我想要多大口径的蝶阀，但具体问到他需要哪种型号的蝶阀产品时，说不上来。在这里小编提醒一句，其实阀的型号也是我们给您报价的一个重要信息之一。蝶阀型号里面包含了很多内容，包括蝶阀的传动方式、连接方式、结构形式、密封面材料、工作压力甚至包括阀体的材料。为方便客户在进行阀门采购时对蝶阀有更多的认知，本篇文章小编为您介绍蝶阀型号表示方法，希望对您有所帮助。

　　In the daily vocabulary that the editor receives, we often encounter a situation where the customer only says what size of butterfly valve they want, but when asked specifically which model of butterfly valve product they need, they cannot say. Here, the editor would like to remind you that the model of the valve is also one of the important information we provide for your quotation. The butterfly valve model includes many contents, including the transmission mode, connection mode, structural form, sealing surface material, working pressure, and even the material of the valve body. To facilitate customers to have a better understanding of butterfly valves when purchasing, this article introduces the method of representing butterfly valve models, hoping to be helpful to you.

　　蝶阀型号表示方法:

　　Butterfly valve model representation method:

　　蝶阀型号按照顺序由附加代号+编制代号+传动方式代号+连接形式代号+结构形式代号+密封材料代号+工作压力等级表示+阀体材质代号组成。具体每一个代号的表示方法如下:

　　The butterfly valve model is composed of additional code+programming code+transmission mode code+connection form code+structural form code+sealing material code+working pressure rating representation+valve body material code in order. The specific representation method for each code is as follows:

　　常见附加代号有BD保温蝶阀、SD伸缩蝶阀、TLD脱硫蝶阀、DKS快速蝶阀、FDBD方形百叶蝶阀。根据蝶阀的类型在型号前面添加，如SD41X，就是代表是法兰伸缩蝶阀。

　　Common additional codes include BD insulated butterfly valve, SD telescopic butterfly valve, TLD desulfurization butterfly valve, DKS quick butterfly valve, FDBD square louver butterfly valve. Add the model number before the butterfly valve type, such as SD41X, which represents a flange expansion butterfly valve.

　　代表蝶阀类型的代号是字母:D:

　　The code representing the type of butterfly valve is the letter D:

　　常见传动方式代号有:手动(省略不写)、涡轮传动代号3、气动代号6、电动代号9;

　　Common transmission mode codes include: manual (omitted), turbo transmission code 3, pneumatic code 6, electric code 9;

　　常用的连接形式代号有:法兰连接代号4、对夹式连接代号7、焊接代号6、内螺纹代号1、卡箍连接代号8:

　　The commonly used connection form codes include: flange connection code 4, clamp type connection code 7, welding code 6, internal thread code 1, clamp connection code 8:

　　蝶阀的结构形式代号有:1代表中线型、2代表双心、3代表三偏心;

　　The structural form codes of butterfly valves are: 1 represents medium line type, 2 represents double center, and 3 represents triple eccentricity;

　　常见密封面材料代号: X-橡胶、F-聚四氣乙烯、H-不锈钢、J-衬胶、T-铜合金、Y-硬质合金、W表示阀体直接加工

　　Common sealing surface material codes: X-rubber, F-polytetrafluoroethylene, H-stainless steel, J-lining rubber, T-copper alloy, Y-hard alloy, W indicates direct processing of valve body

　　压力等级表示:国内常用到的压力等级有PN1.0Mpa(10公斤)、PN1.6mpa(16公斤)PN2.5mpa(25公斤)、PN4.0mpa(40公斤)、其中PN代表是国内压力的代号，MPA是压力的单位，1公斤=0.1Mpa;

　　Pressure level representation: The commonly used pressure levels in China include PN1.0Mpa (10 kg), PN1.6mpa (16 kg), PN2.5mpa (25 kg), PN4.0mpa (40 kg), where PN represents the code for domestic pressure, MPA is the unit of pressure, and 1 kg=0.1Mpa;

　　常用阀体材质代号有:铸钢-C、铸铁-Z、球墨铸铁-Q、不锈钢304-P、不锈钢316-R;

　　Common valve body material codes include: cast steel - C, cast iron - Z, ductile iron - Q, stainless steel 304-P, stainless steel 316-R;
