Raws li cov xwm txheej sib txawv thiab kev xav tau, lub twj tso kua mis valve tuaj yeem muab faib ua ntau hom, feem ntau suav nrog: cov tshuab foob, ntim foob, roj foob thiab kua foob.Txhua hom foob muaj nws tus yam ntxwv tshwj xeeb thiab daim ntawv thov ntau yam.
1, mechanical seal: mechanical seal yog ib hom twj tso kua mis valve foob, nws muaj precision siab, siab zog, siab hnav tsis kam thiab lwm yam zoo, haum rau high-speed rotation thiab siab sealing zaus.Lub tshuab foob tau txais cov qauv ntawm kev sib txhuam dynamic thiab zoo li qub nplhaib sib txhuam, thiab qhov kawg ntawm lub ntsej muag ntawm lub nplhaib dynamic thiab zoo li qub yog perpendicular rau ib leeg thiab muaj cov txheeb ze zawv zawg kev sib txhuam, uas tuaj yeem ua tiav xoom to.Mechanical seals muaj lub neej ua haujlwm ntev thiab cov nqi kho mob tsawg.
2, packing seal: packing seal yog lub twj tso kua mis yooj yim valve foob, nws muaj qhov zoo ntawm cov qauv yooj yim, yooj yim txij nkawm, haum rau atmospheric siab lossis tsis tshua muaj siab sealing zaus.Lub foob ntim khoom yog tsim los ntawm cov khoom ntim mos, xws li asbestos fiber, graphite, thiab lwm yam, uas yog compressed thiab nruj nreem txuas rau sab hauv ntawm lub twj tso kua mis lossis valve kom ua tiav cov nyhuv sealing.Tus nqi ntawm cov ntim ntim khoom yog pheej yig dua, thiab nws yog qhov tsim nyog rau qee qhov kev thov qis qis.
3, roj foob kua foob: roj foob kua foob yog lub twj tso kua mis tshwj xeeb valve foob, nws tuaj yeem tiv thaiv cov pa tawm ntawm cov pa los yog kua tawm.Cov kua foob tau txais cov qauv tsim tshwj xeeb, uas tuaj yeem ua kom lub siab ntawm cov pa roj los yog kua nruab nrab nyob rau hauv ib qho chaw, thiaj li ua tiav cov nyhuv sealing.Gas seal kua foob yog tsim rau qee qhov tshwj xeeb daim ntawv thov scenarios xws li flammable thiab explosive, lom thiab teeb meem lub sij hawm.
