蝶閥知識：氣動蝶閥的工作原理
氣(qi)(qi)(qi)動(dong)蝶(die)(die)閥(fa)是(shi)由一個氣(qi)(qi)(qi)動(dong)執行(xing)機(ji)構和蝶(die)(die)閥(fa)組(zu)合而成的閥(fa)門(men)，氣(qi)(qi)(qi)動(dong)蝶(die)(die)閥(fa)因為(wei)在(zai)蝶(die)(die)閥(fa)上(shang)安裝了氣(qi)(qi)(qi)動(dong)執行(xing)器(qi)，電磁閥(fa)線圈，空氣(qi)(qi)(qi)過濾(lv)減(jian)壓(ya)閥(fa)，信號反饋裝置，使其能(neng)夠(gou)適應一些(xie)高危(wei)的工況環(huan)境，減(jian)小了人力操(cao)作可能(neng)帶來(lai)的危(wei)險，特別是(shi)在(zai)低壓(ya)大中口徑管道(dao)上(shang)，氣(qi)(qi)(qi)動(dong)蝶(die)(die)閥(fa)的使用越(yue)來(lai)越(yue)多，除此之外(wai)大口徑的氣(qi)(qi)(qi)動(dong)蝶(die)(die)閥(fa)相(xiang)對(dui)于其他氣(qi)(qi)(qi)動(dong)閥(fa)門(men)（氣(qi)(qi)(qi)動(dong)球閥(fa)，氣(qi)(qi)(qi)動(dong)切斷閥(fa)，氣(qi)(qi)(qi)動(dong)閘(zha)閥(fa)，氣(qi)(qi)(qi)動(dong)截止閥(fa)）也(ye)更經濟實惠。

氣(qi)(qi)動(dong)(dong)(dong)蝶閥使用(yong)(yong)(yong)(yong)范(fan)圍廣泛，是因為其結構簡單(dan)，更方便檢修和維(wei)護，并且啟閉(bi)迅速，不(bu)僅可(ke)以(yi)大(da)大(da)提(ti)高工(gong)作(zuo)的(de)(de)效(xiao)率，還能(neng)夠減少檢修和維(wei)護時(shi)間，降低人力(li)成本。另外，氣(qi)(qi)動(dong)(dong)(dong)蝶閥可(ke)根據顧客的(de)(de)要求，選用(yong)(yong)(yong)(yong)不(bu)同(tong)(tong)材質(zhi)的(de)(de)密封圈和零部件，以(yi)適應不(bu)同(tong)(tong)的(de)(de)介質(zhi)和工(gong)況(kuang)環(huan)境，從而使氣(qi)(qi)動(dong)(dong)(dong)蝶閥發(fa)揮其使用(yong)(yong)(yong)(yong)效(xiao)果。氣(qi)(qi)動(dong)(dong)(dong)蝶閥的(de)(de)執行(xing)器(qi)有單(dan)作(zuo)用(yong)(yong)(yong)(yong)（常(chang)閉(bi)式）和雙(shuang)作(zuo)用(yong)(yong)(yong)(yong)（常(chang)開式）形式之分，單(dan)作(zuo)用(yong)(yong)(yong)(yong)執行(xing)器(qi)具有彈(dan)簧復位(wei)的(de)(de)功能(neng)，可(ke)以(yi)在(zai)失(shi)(shi)去氣(qi)(qi)源時(shi)自動(dong)(dong)(dong)關閉(bi)或開啟，安全系數更高！而雙(shuang)作(zuo)用(yong)(yong)(yong)(yong)氣(qi)(qi)動(dong)(dong)(dong)執行(xing)器(qi)，在(zai)失(shi)(shi)去氣(qi)(qi)源時(shi)，氣(qi)(qi)動(dong)(dong)(dong)執行(xing)器(qi)失(shi)(shi)去動(dong)(dong)(dong)力(li)，閥位(wei)會保持在(zai)失(shi)(shi)氣(qi)(qi)時(shi)所在(zai)的(de)(de)位(wei)置。
氣動蝶閥的工作原理：
氣(qi)動(dong)(dong)蝶閥(fa)(fa)(fa)是(shi)給蝶閥(fa)(fa)(fa)安裝了氣(qi)動(dong)(dong)執行器，來替(ti)代人力(li)(li)操作。它的工作原(yuan)理(li)是(shi)以壓縮空氣(qi)為(wei)動(dong)(dong)力(li)(li)源，驅動(dong)(dong)閥(fa)(fa)(fa)桿(gan)(gan)轉動(dong)(dong)，閥(fa)(fa)(fa)桿(gan)(gan)又帶動(dong)(dong)圓盤形蝶板(ban)旋轉，蝶板(ban)的初始位置根據實際需求而(er)定，蝶板(ban)從(cong)初始位置旋轉，當蝶板(ban)旋轉到(dao)與閥(fa)(fa)(fa)體呈(cheng)90°時(shi)，氣(qi)動(dong)(dong)蝶閥(fa)(fa)(fa)為(wei)全開狀(zhuang)態，當蝶閥(fa)(fa)(fa)旋轉到(dao)與閥(fa)(fa)(fa)體呈(cheng)0°或180°時(shi)，氣(qi)動(dong)(dong)蝶閥(fa)(fa)(fa)為(wei)關閉(bi)狀(zhuang)態。
