蝶閥又叫翻板閥,是一種結(jié)構(gòu)簡單的調(diào)節(jié)閥,可用于低壓管道介質(zhì)的開關(guān)控制的蝶閥是指關(guān)閉件(閥瓣或蝶板)為圓盤,圍繞閥軸旋轉(zhuǎn)來達到開啟與關(guān)閉的一種閥。

閥門可用于控制空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品、液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動。在管道上主要起切斷和節(jié)流作用。蝶閥啟閉件是一個圓盤形的蝶板,在閥體內(nèi)繞其自身的軸線旋轉(zhuǎn),從而達到啟閉或調(diào)節(jié)的目的。

Butterfly valves, also known as flap valves, are regulating valves with a simple structure. They can be used for switching control of low-pressure pipeline media The closing parts (discs) are discs that rotate to open and close the valve.

Valves can be used to control the flow of various types of fluids such as air, water, steam, corrosive media, mud, oil, liquid metals and radioactive media. They are mainly used to cut off and throttle flow in pipelines.
