氣動陶瓷旋轉出料閥主要適用于火電廠干灰系統灰、渣出料的啟閉之用，也適用于礦山、石灰廠、水泥廠等有磨損、腐蝕的粉塵介質的進料啟閉。本閥門具有密封性能好，耐高溫，耐磨性強，啟閉靈活，無卡灰及積灰現象，使用壽命長等特點。
氣動陶瓷旋轉出料閥,氣動出料閥特點說明: 的(de)(de)(de)啟閉件是(shi)閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)，閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)的(de)(de)(de)運(yun)(yun)動方向與流體(ti)(ti)方向相垂直，閘(zha)(zha)(zha)(zha)(zha)閥(fa)(fa)只能(neng)(neng)(neng)作全開(kai)(kai)和(he)(he)全關(guan)(guan),不(bu)能(neng)(neng)(neng)作調(diao)節(jie)和(he)(he)節(jie)流。閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)有(you)兩個(ge)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)面(mian),最常(chang)用的(de)(de)(de)模(mo)式閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)閥(fa)(fa)的(de)(de)(de)兩個(ge)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)面(mian)形(xing)成(cheng)楔(xie)形(xing)、楔(xie)形(xing)角(jiao)隨參數(shu)而異,通(tong)(tong)常(chang)為(wei)(wei)(wei)50,介質溫度(du)不(bu)高(gao)時(shi)為(wei)(wei)(wei)2°52'。楔(xie)式閘(zha)(zha)(zha)(zha)(zha)閥(fa)(fa)的(de)(de)(de)閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)可(ke)以(yi)做成(cheng)一個(ge)整 體(ti)(ti)，叫(jiao)做剛性(xing)閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)；也可(ke)以(yi)做成(cheng)能(neng)(neng)(neng)產(chan)生微(wei)量(liang)變形(xing)的(de)(de)(de)閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban),以(yi)改善其工藝性(xing),彌補密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)面(mian)角(jiao)度(du)在(zai)加工過程(cheng)中產(chan)生的(de)(de)(de)偏差,這種(zhong)閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)叫(jiao)做彈性(xing)閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)。閘(zha)(zha)(zha)(zha)(zha)閥(fa)(fa)關(guan)(guan)閉時(shi),密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)面(mian)可(ke)以(yi)只依靠(kao)(kao)介質壓(ya)(ya)力來密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng),即依靠(kao)(kao)介質壓(ya)(ya)力將(jiang)閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)的(de)(de)(de)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)面(mian)壓(ya)(ya)向另一側的(de)(de)(de)閥(fa)(fa)座來保證(zheng)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)面(mian)的(de)(de)(de)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)，這就是(shi)自密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)。大(da)部(bu)分是(shi)采用強(qiang)制密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de),即閥(fa)(fa)門關(guan)(guan)閉時(shi)，要依靠(kao)(kao)外(wai)力強(qiang)行(xing)將(jiang)閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)壓(ya)(ya)向閥(fa)(fa)座,以(yi)保證(zheng)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)面(mian)的(de)(de)(de)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)性(xing)。閘(zha)(zha)(zha)(zha)(zha)閥(fa)(fa)的(de)(de)(de)閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)隨閥(fa)(fa)桿(gan)一起作直線運(yun)(yun)動的(de)(de)(de)，叫(jiao)升(sheng)降(jiang)桿(gan)閘(zha)(zha)(zha)(zha)(zha)閥(fa)(fa)亦叫(jiao)明(ming)桿(gan)閘(zha)(zha)(zha)(zha)(zha)閥(fa)(fa)。通(tong)(tong)常(chang)在(zai)升(sheng)降(jiang)桿(gan)上有(you)梯形(xing)螺紋，通(tong)(tong)過閥(fa)(fa)門頂端(duan)的(de)(de)(de)螺母以(yi)及閥(fa)(fa)體(ti)(ti)上的(de)(de)(de)導槽，將(jiang)旋轉(zhuan)(zhuan)運(yun)(yun)動變為(wei)(wei)(wei)直線運(yun)(yun)動,也就是(shi)將(jiang)操作轉(zhuan)(zhuan)矩變為(wei)(wei)(wei)操作推力。開(kai)(kai)啟閥(fa)(fa)門時(shi)，當閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)提(ti)升(sheng)高(gao)度(du)等于閥(fa)(fa)門通(tong)(tong)徑的(de)(de)(de)1：1倍時(shi)，流體(ti)(ti)的(de)(de)(de)通(tong)(tong)道(dao)完(wan)全暢通(tong)(tong)，但在(zai)運(yun)(yun)行(xing)時(shi)，此位(wei)置(zhi)是(shi)無法監視的(de)(de)(de)。實際(ji)使用時(shi)，是(shi)以(yi)閥(fa)(fa)桿(gan)的(de)(de)(de)頂點(dian)(dian)作為(wei)(wei)(wei)標志(zhi)，即開(kai)(kai)不(bu)動的(de)(de)(de)位(wei)置(zhi)，作為(wei)(wei)(wei)它的(de)(de)(de)全開(kai)(kai)位(wei)置(zhi)。為(wei)(wei)(wei)考慮(lv)溫度(du)變化出現鎖(suo)死現象(xiang),通(tong)(tong)常(chang)在(zai)開(kai)(kai)到頂點(dian)(dian)位(wei)置(zhi)上,再倒回1/2－1圈,作為(wei)(wei)(wei)全開(kai)(kai)閥(fa)(fa)門的(de)(de)(de)位(wei)置(zhi)。因此,的(de)(de)(de)全開(kai)(kai)位(wei)置(zhi)，按閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)的(de)(de)(de)位(wei)置(zhi)即行(xing)程(cheng)來確定(ding)。有(you)的(de)(de)(de)閘(zha)(zha)(zha)(zha)(zha)閥(fa)(fa),閥(fa)(fa)桿(gan)螺母設在(zai)閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)上，手輪(lun)轉(zhuan)(zhuan)動帶動閥(fa)(fa)桿(gan)轉(zhuan)(zhuan)動,而使閘(zha)(zha)(zha)(zha)(zha)板(ban)(ban)(ban)提(ti)升(sheng),這種(zhong)閥(fa)(fa)門叫(jiao)做旋轉(zhuan)(zhuan)桿(gan)閘(zha)(zha)(zha)(zha)(zha)閥(fa)(fa)或叫(jiao)暗桿(gan)閘(zha)(zha)(zha)(zha)(zha)閥(fa)(fa)。
