在小編日常接到的詞盤中，經常會碰到這樣一種情況，客戶只說我想要多大口徑的蝶閥，但具體問到他需要哪種型號的蝶閥產品時，說不上來。在這里小編提醒一句，其實閥的型號也是我們給您報價的一個重要信息之一。蝶閥型號里面包含了很多內容，包括蝶閥的傳動方式、連接方式、結構形式、密封面材料、工作壓力甚至包括閥體的材料。為方便客戶在進行閥門采購時對蝶閥有更多的認知，本篇文章小編為您介紹蝶閥型號表示方法，希望對您有所幫助。

　　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. 

　　蝶閥型號表示方法:

　　Butterfly valve model representation method:

　　蝶閥型號按照順序由附加代號+編制代號+傳動方式代號+連接形式代號+結構形式代號+密封材料代號+工作壓力等級表示+閥體材質代號組成。具體每一個代號的表示方法如下:

　　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:

　　常見附加代號有BD保溫蝶閥、SD伸縮蝶閥、TLD脫硫蝶閥、DKS快速蝶閥、FDBD方形百葉蝶閥。根據蝶閥的類型在型號前面添加，如SD41X，就是代表是法蘭伸縮蝶閥。

　　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.

　　代表蝶閥類型的代號是字母:D:

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

　　常見傳動方式代號有:手動(省略不寫)、渦輪傳動代號3、氣動代號6、電動代號9;

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

　　常用的連接形式代號有:法蘭連接代號4、對夾式連接代號7、焊接代號6、內螺紋代號1、卡箍連接代號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:

　　蝶閥的結構形式代號有:1代表中線型、2代表雙心、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;

　　常見密封面材料代號: X-橡膠、F-聚四氣乙烯、H-不銹鋼、J-襯膠、T-銅合金、Y-硬質合金、W表示閥體直接加工

　　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

　　壓力等級表示:國內常用到的壓力等級有PN1.0Mpa(10公斤)、PN1.6mpa(16公斤)PN2.5mpa(25公斤)、PN4.0mpa(40公斤)、其中PN代表是國內壓力的代號，MPA是壓力的單位，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;

　　常用閥體材質代號有:鑄鋼-C、鑄鐵-Z、球墨鑄鐵-Q、不銹鋼304-P、不銹鋼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;
