Mos foob:
Ob sab ntawm lub sealing khub yog cov ntaub ntawv hlau, thiab lwm sab yog elastic non-metallic khoom, uas yog hu ua "soft seal". Lub sealing kev ua tau zoo ntawm lub foob foob rau npauj npaim valve yog qhov zoo, tab sis nws tsis tiv taus qhov kub thiab txias, thiab nws yooj yim rau abrase thiab cov khoom siv tshuab tsis zoo, xws li hlau, roj hmab, PTFE thiab lwm yam. Lub rooj zaum muag muag yog ua los ntawm cov khoom siv tsis yog hlau nrog qee lub zog, hardness thiab kub tsis kam. Nws muaj kev sib khi zoo thiab tuaj yeem ua tiav xoom xoom, tab sis nws lub neej kev pabcuam thiab kev hloov pauv mus rau qhov kub tsis zoo.
Hard seal:
Ob sab ntawm lub sealing khub yog cov khoom siv hlau lossis lwm yam khoom siv tawv, uas yog hu ua "hard seal". Lub sealing kev ua tau zoo ntawm hom tawv foob tsis zoo, tab sis nws muaj qhov kub thiab txias tsis kam, hnav tsis kam thiab kev ua haujlwm zoo, xws li hlau, hlau; hlau, tooj liab; hlau, graphite; hlau, hlau alloy; (steel ntawm no kuj yog cam khwb cia hlau, cam khwb cia hlau, hlau alloy kuj yuav surfacing, txau alloy). Lub zog foob yog ua los ntawm cov hlau, thiab nws sealing kev ua tau zoo kuj tsis zoo, tab sis ib txhia manufacturers hais tias nws yuav ua tau xoom to. Mos foob tsis tuaj yeem ua tau raws li cov txheej txheem rau qee cov ntaub ntawv corrosive, thiab tawv foob tuaj yeem daws qhov teeb meem! Ob hom ntsaws ruaj ruaj no tuaj yeem ua tiav rau ib leeg. Nyob rau hauv cov nqe lus ntawm sealing kev ua tau zoo, mos sealing kuj zoo, tab sis tam sim no lub sealing kev ua tau zoo ntawm lub sealing hard sealing kuj tseem ua tau raws li qhov yuav tsum tau ua! Qhov zoo ntawm cov foob mos yog qhov zoo sealing kev ua tau zoo, tab sis qhov tsis zoo yog yooj yim aging, hnav thiab luv luv kev pab cuam lub neej. Lub neej kev pab cuam ntawm lub foob tawv yog ntev, tab sis nws cov sealing kev ua tau zoo yog phem dua li ntawm cov foob mos.
Cov qauv sib txawv yog raws li nram no:
1. Cov qauv sib txawv: mos foobnpauj npaim valvefeem ntau yog nruab nrab linear, thiab lub foob tawv feem ntau yog ib qho eccentric npauj npaim li qub, ob chav eccentric npauj npaim li qub thiab triple eccentric npauj npaim li qub.
2. Kub tsis kam: mos foob rau ib puag ncig kub. Lub foob tawv tawv tuaj yeem siv rau hauv qhov kub thiab txias, qhov kub thiab txias ib puag ncig.
3. Siab: mos foob, tsis tshua muaj siab mus rau ib txwm siab, tawv foob kuj tuaj yeem siv rau hauv nruab nrab thiab siab siab.
4. sealing kev ua tau zoo: mos sealingnpauj npaim valvethiab peb eccentric nyuaj sealingnpauj npaim valvemuaj kev sealing zoo dua. Peb eccentric npauj npaim valve tuaj yeem ua kom zoo sealing kev ua tau zoo nyob rau hauv kev kub siab thiab kub ib puag ncig. Vim yog cov yam ntxwv ntawm kev yooj yim installation, txij nkawm thiab cov qauv yooj yim, npauj npaim valve hloovrooj vag valvethiabntiaj teb valvenyob rau hauv ntau thiab ntau zaus.
