蝶阀的种类
Types of butterfly valves
蝶阀的分类有很多种，不同的分类形式可以把蝶阀分成不同的种类。下面咱们具体来说说。
There are many kinds of butterfly valves. Different types of butterfly valves can be divided into different types. Let's talk about it in detail.
1.按照连接形式的不同，可以分为对夹式蝶阀、法兰式蝶阀、焊接蝶阀、丝扣蝶阀、卡箍蝶阀等等。最常用的连接形式有对夹式蝶阀和法兰式蝶阀。
1. According to the different connection forms, butterfly valves can be divided into pair-clamp butterfly valves, flange butterfly valves, welding butterfly valves, Button Butterfly valves, clamp butterfly valves and so on. The most commonly used connection forms are butterfly valves with pair clamps and flanged butterfly valves.
2.按照传动方式的不同，可以分为手柄蝶阀、涡轮蝶阀、气动蝶阀、电动蝶阀、液动蝶阀、电磁阀等。最常见到的传动方式有手柄、涡轮、气动和电动。而手柄蝶阀和涡轮蝶阀统称为手动蝶阀。
2. According to the different transmission modes, it can be divided into handle butterfly valve, turbine butterfly valve, pneumatic butterfly valve, electric butterfly valve, hydraulic butterfly valve, solenoid valve, etc. The most common transmission modes are handles, turbines, pneumatic and electric. Handle butterfly valve and turbine butterfly valve are collectively called manual butterfly valve.
3.按照密封面材质的不同，可以分为软密封蝶阀和硬密封蝶阀。软密封蝶阀密封性能好于硬密封蝶阀，软密封蝶阀密封面常用材质有EPDM、丁腈橡胶、PTFE。硬密封蝶阀主要用在高温高压的工况中。
3. According to the different material of sealing surface, it can be divided into soft sealing butterfly valve and hard sealing butterfly valve. Soft-sealed butterfly valves have better sealing performance than hard-sealed butterfly valves. The common materials used for sealing surface of soft-sealed butterfly valves are EPDM, NBR and PTFE. Hard-sealed butterfly valves are mainly used in high temperature and high pressure conditions.
4.按照结构形式的不同，可以分为中线蝶阀、单偏心蝶阀、双偏心蝶阀和三偏心蝶阀。其中中线蝶阀一般用软密封；偏心蝶阀用硬密封。三偏心蝶阀是目前性能最好的阀门，既有软密封蝶阀优异的密封性能，又有硬密封蝶阀耐高温高压耐腐蚀的特点。
4. According to the different structural forms, it can be divided into midline butterfly valve, single eccentric butterfly valve, double eccentric butterfly valve and three eccentric butterfly valve. The middle line butterfly valve is generally soft sealed, while the eccentric butterfly valve is hard sealed. Tri-eccentric butterfly valve is the best valve at present. It not only has excellent sealing performance of soft-sealed butterfly valve, but also has the characteristics of high temperature, high pressure and corrosion resistance of hard-sealed butterfly valve.
