Z973刀型閘閥 不銹鋼調節閥
閘(zha)(zha)閥(fa)又(you)稱刀門閘(zha)(zha)閥(fa)，刀型(xing)漿液(ye)閥(fa)，它的(de)(de)(de)啟(qi)閉件是(shi)閘(zha)(zha)板(ban)(ban)(ban)(ban)(ban)，閘(zha)(zha)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)運動方(fang)向(xiang)與(yu)流體方(fang)向(xiang)相垂(chui)直，靠可以切割(ge)纖維材料的(de)(de)(de)刀刃(ren)形閘(zha)(zha)板(ban)(ban)(ban)(ban)(ban)來(lai)切斷介質(zhi)，閘(zha)(zha)板(ban)(ban)(ban)(ban)(ban)有(you)兩個密(mi)封面,最常用(yong)的(de)(de)(de)模式(shi)閘(zha)(zha)板(ban)(ban)(ban)(ban)(ban)閥(fa)的(de)(de)(de)兩個密(mi)封面形成(cheng)楔(xie)形、楔(xie)形角隨閥(fa)門參數而(er)異,通常為50,楔(xie)式(shi)刀型(xing)閘(zha)(zha)閥(fa)的(de)(de)(de)閘(zha)(zha)板(ban)(ban)(ban)(ban)(ban)可以做成(cheng)一個整體，叫(jiao)做剛(gang)性閘(zha)(zha)板(ban)(ban)(ban)(ban)(ban)；也可以做成(cheng)能產生微(wei)量變(bian)形的(de)(de)(de)閘(zha)(zha)板(ban)(ban)(ban)(ban)(ban),以改善其工(gong)藝性,彌補密(mi)封面角度在(zai)(zai)加工(gong)過程中產生的(de)(de)(de)偏差,這種閘(zha)(zha)板(ban)(ban)(ban)(ban)(ban)叫(jiao)做彈性閘(zha)(zha)板(ban)(ban)(ban)(ban)(ban)。閥(fa)體實際(ji)上(shang)不(bu)存在(zai)(zai)腔室，閘(zha)(zha)板(ban)(ban)(ban)(ban)(ban)在(zai)(zai)側(ce)面導(dao)向(xiang)槽內升降(jiang)，并由底(di)部(bu)的(de)(de)(de)凸耳(er)緊壓(ya)在(zai)(zai)閥(fa)座上(shang)，如(ru)需達到(dao)較(jiao)高的(de)(de)(de)介質(zhi)密(mi)封性時，可選用(yong)O形密(mi)封閥(fa)座實現雙向(xiang)密(mi)封。刀閘(zha)(zha)閥(fa)具有(you)較(jiao)小的(de)(de)(de)安裝(zhuang)空間，工(gong)作(zuo)壓(ya)力(li)低，不(bu)易堆積雜(za)物(wu)，價格較(jiao)低。
