蝶(die)(die)(die)閥(Butterfly Valve)：蝶(die)(die)(die)閥是(shi)指關(guan)(guan)閉件(jian)(閥瓣或(huo)蝶(die)(die)(die)板(ban))為(wei)圓盤，圍繞(rao)閥軸(zhou)旋轉來(lai)達到開(kai)啟(qi)(qi)(qi)與關(guan)(guan)閉的一(yi)種(zhong)閥，在管道上主(zhu)要(yao)起切(qie)斷和節流(liu)用(yong)(yong)。蝶(die)(die)(die)閥啟(qi)(qi)(qi)閉件(jian)是(shi)一(yi)個圓盤形(xing)的蝶(die)(die)(die)板(ban)，在閥體內繞(rao)其自(zi)身(shen)的軸(zhou)線旋轉，從而(er)達到啟(qi)(qi)(qi)閉或(huo)調節的目的。蝶(die)(die)(die)閥全(quan)開(kai)到全(quan)關(guan)(guan)通常(chang)是(shi)小于90° ，蝶(die)(die)(die)閥和蝶(die)(die)(die)桿(gan)本(ben)身(shen)沒有自(zi)鎖能(neng)力(li)，為(wei)了蝶(die)(die)(die)板(ban)的定位，要(yao)在閥桿(gan)上加(jia)裝蝸輪減(jian)速器。采(cai)用(yong)(yong)蝸輪減(jian)速器，不僅可以使(shi)蝶(die)(die)(die)板(ban)具有自(zi)鎖能(neng)力(li)，使(shi)蝶(die)(die)(die)板(ban)停止在任意位置上，還能(neng)改(gai)善閥門的操(cao)作(zuo)性能(neng)。工(gong)業(ye)專(zhuan)用(yong)(yong)蝶(die)(die)(die)閥的特點能(neng)耐高(gao)溫，適用(yong)(yong)壓力(li)范圍也較(jiao)高(gao)，閥門公(gong)稱通徑大(da)，閥體采(cai)用(yong)(yong)碳鋼制(zhi)造(zao)，閥板(ban)的密封圈采(cai)用(yong)(yong)金屬環代替橡(xiang)膠環。大(da)型高(gao)溫蝶(die)(die)(die)閥采(cai)用(yong)(yong)鋼板(ban)焊接(jie)制(zhi)造(zao)，主(zhu)要(yao)用(yong)(yong)于高(gao)溫介質的煙風道和煤氣(qi)管道。
蝶閥的優點如(ru)下(xia)：1、啟閉方便迅速、省力、流體阻力小，可以經常操(cao)作。2、結構(gou)簡單，體積小，重量輕(qing)。3、可以運送泥漿，在管道口積存(cun)液體最少。4、低壓下(xia)，可以實現良(liang)好(hao)的密(mi)封。5、調節性能好(hao)。
蝶閥(fa)的缺點如(ru)下(xia)：1、使(shi)用壓力(li)和工(gong)作(zuo)溫度范圍小。2、密封性較(jiao)差。
蝶閥按結構(gou)形式(shi)可分為(wei)偏置(zhi)板(ban)式(shi)、垂直(zhi)板(ban)式(shi)、斜板(ban)式(shi)和(he)杠桿式(shi)。按密(mi)封(feng)(feng)(feng)形式(shi)可分為(wei)較密(mi)封(feng)(feng)(feng)型(xing)和(he)硬密(mi)封(feng)(feng)(feng)型(xing)兩種(zhong)。軟密(mi)封(feng)(feng)(feng)型(xing)一(yi)般采用橡膠(jiao)環(huan)密(mi)封(feng)(feng)(feng)，硬密(mi)封(feng)(feng)(feng)型(xing)通(tong)常采用金屬環(huan)密(mi)封(feng)(feng)(feng)。按連接型(xing)式(shi)可分為(wei)法蘭連接和(he)對夾式(shi)連接；按傳(chuan)動(dong)方(fang)式(shi)可分為(wei)手動(dong)、齒輪傳(chuan)動(dong)、氣(qi)動(dong)、液動(dong)和(he)電動(dong)幾種(zhong)。
蝶閥(fa)的安(an)裝與維護應注意以下事項：1、在安(an)裝時，閥(fa)瓣要停在關閉的位置上。2、開啟位置應按(an)蝶板的旋轉角度來確定。3、帶(dai)有旁通(tong)閥(fa)的蝶閥(fa)，開啟前(qian)應先打(da)開旁通(tong)閥(fa)。4、重量大的蝶閥(fa)，應設置牢固的基礎(chu)。
