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(dá)到開啟與關(guān)閉的一種閥。 </p> <p> 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(dá)到啟閉或調(diào)節(jié)的目的。 </p> <p> 蝶閥是用圓盤式啟閉件往復(fù)回轉(zhuǎn)90°左右來開啟、關(guān)閉或調(diào)節(jié)介質(zhì)流量的一種閥門。蝶閥不僅結(jié)構(gòu)簡單，福建德國真空管道蝶閥重量、體積小、重量輕、材料耗用省、安裝尺寸小、驅(qū)動力矩小、操作簡便、迅速，并且還可以同時具有良好的流量調(diào)節(jié)功能和關(guān)閉密封特性，福建德國真空管道蝶閥重量，是近十幾年來發(fā)展**快的閥門品種之一。蝶閥的使用非常很多。其使用的品種和數(shù)量仍在繼續(xù)擴(kuò)大，并向高溫，福建德國真空管道蝶閥重量、高壓、大口徑、高密封性、長壽命、優(yōu)良的調(diào)節(jié)特性，以及一閥多功能發(fā)展。其可靠性及其他性能指標(biāo)均達(dá)到較高水平。
