刀型閘閥/漿液閥 介紹

刀型閘閥又稱刀門(men)閘(zha)(zha)閥(fa)(fa)，刀型漿液閥(fa)(fa)，它的啟閉件是閘(zha)(zha)板(ban)(ban)(ban)(ban)，閘(zha)(zha)板(ban)(ban)(ban)(ban)的運動方向與流體方向相(xiang)垂直，靠(kao)可以(yi)(yi)切(qie)割纖維(wei)材(cai)料的刀刃形(xing)閘(zha)(zha)板(ban)(ban)(ban)(ban)來(lai)切(qie)斷介(jie)質，閘(zha)(zha)板(ban)(ban)(ban)(ban)有兩(liang)個密(mi)封面(mian),最(zui)常用(yong)的模式閘(zha)(zha)板(ban)(ban)(ban)(ban)閥(fa)(fa)的兩(liang)個密(mi)封面(mian)形(xing)成(cheng)(cheng)楔(xie)形(xing)、楔(xie)形(xing)角隨閥(fa)(fa)門(men)參數而異,通常為50,楔(xie)式刀型閘(zha)(zha)閥(fa)(fa)的閘(zha)(zha)板(ban)(ban)(ban)(ban)可以(yi)(yi)做(zuo)(zuo)成(cheng)(cheng)一個整(zheng)體，叫做(zuo)(zuo)剛性閘(zha)(zha)板(ban)(ban)(ban)(ban)；也可以(yi)(yi)做(zuo)(zuo)成(cheng)(cheng)能產生(sheng)微量變形(xing)的閘(zha)(zha)板(ban)(ban)(ban)(ban),以(yi)(yi)改善其工(gong)藝性,彌補密(mi)封面(mian)角度(du)在(zai)加工(gong)過程中產生(sheng)的偏差,這種(zhong)閘(zha)(zha)板(ban)(ban)(ban)(ban)叫做(zuo)(zuo)彈性閘(zha)(zha)板(ban)(ban)(ban)(ban)。閥(fa)(fa)體實際上不存在(zai)腔室，閘(zha)(zha)板(ban)(ban)(ban)(ban)在(zai)側面(mian)導向槽內(nei)升降，并(bing)由底部的凸耳緊(jin)壓在(zai)閥(fa)(fa)座上，如需達到較(jiao)高的介(jie)質密(mi)封性時(shi)，可選(xuan)用(yong)O形(xing)密(mi)封閥(fa)(fa)座實現雙向密(mi)封。刀閘(zha)(zha)閥(fa)(fa)具有較(jiao)小(xiao)的安裝空(kong)間，工(gong)作壓力低，不易堆積(ji)雜(za)物，價格較(jiao)低。
