刀型閘閥/漿液閥 介紹

刀型閘閥又稱刀(dao)門(men)閘(zha)閥(fa)(fa)(fa)，刀(dao)型(xing)漿(jiang)液(ye)閥(fa)(fa)(fa)，它的(de)(de)啟(qi)閉件是閘(zha)板(ban)(ban)(ban)(ban)，閘(zha)板(ban)(ban)(ban)(ban)的(de)(de)運動方(fang)(fang)向(xiang)與流(liu)體方(fang)(fang)向(xiang)相垂直，靠可以(yi)(yi)切割纖維材料的(de)(de)刀(dao)刃形閘(zha)板(ban)(ban)(ban)(ban)來切斷介質，閘(zha)板(ban)(ban)(ban)(ban)有兩(liang)個(ge)密(mi)(mi)封(feng)(feng)(feng)面,最(zui)常用的(de)(de)模(mo)式(shi)閘(zha)板(ban)(ban)(ban)(ban)閥(fa)(fa)(fa)的(de)(de)兩(liang)個(ge)密(mi)(mi)封(feng)(feng)(feng)面形成楔(xie)形、楔(xie)形角隨閥(fa)(fa)(fa)門(men)參(can)數而異(yi),通常為50,楔(xie)式(shi)刀(dao)型(xing)閘(zha)閥(fa)(fa)(fa)的(de)(de)閘(zha)板(ban)(ban)(ban)(ban)可以(yi)(yi)做成一個(ge)整(zheng)體，叫做剛性(xing)閘(zha)板(ban)(ban)(ban)(ban)；也可以(yi)(yi)做成能產生(sheng)微量(liang)變(bian)形的(de)(de)閘(zha)板(ban)(ban)(ban)(ban),以(yi)(yi)改善其工藝性(xing),彌(mi)補密(mi)(mi)封(feng)(feng)(feng)面角度在(zai)(zai)加工過程中產生(sheng)的(de)(de)偏差,這種閘(zha)板(ban)(ban)(ban)(ban)叫做彈(dan)性(xing)閘(zha)板(ban)(ban)(ban)(ban)。閥(fa)(fa)(fa)體實(shi)(shi)際(ji)上(shang)(shang)不(bu)存在(zai)(zai)腔(qiang)室，閘(zha)板(ban)(ban)(ban)(ban)在(zai)(zai)側面導向(xiang)槽內升(sheng)降，并由底部的(de)(de)凸耳緊壓在(zai)(zai)閥(fa)(fa)(fa)座上(shang)(shang)，如(ru)需達到較高的(de)(de)介質密(mi)(mi)封(feng)(feng)(feng)性(xing)時，可選用O形密(mi)(mi)封(feng)(feng)(feng)閥(fa)(fa)(fa)座實(shi)(shi)現雙向(xiang)密(mi)(mi)封(feng)(feng)(feng)。刀(dao)閘(zha)閥(fa)(fa)(fa)具有較小的(de)(de)安裝空(kong)間(jian)，工作(zuo)壓力低(di)(di)，不(bu)易堆積雜(za)物，價(jia)格較低(di)(di)。
