Mos foob:
Ntawm ob sab ntawm lub sealing khub, ib qho yog ua los ntawm cov khoom siv hlau, thiab lwm qhov yog ua los ntawm cov khoom siv elastic uas tsis yog xim hlau, hu ua "mos foob."
Hom foob no muaj kev sib khi zoo dua tab sis tsis tiv taus qhov kub thiab txias, hnav tau yooj yim, thiab muaj cov khoom siv tsis zoo. Xws li steel + roj hmab, steel + PTFE, thiab lwm yam.
Lub rooj zaum muag muag yog ua los ntawm cov khoom tsis yog xim hlau nrog lub zog tshwj xeeb, hardness, thiab kub tsis kam. Nws muaj kev sib khi zoo thiab tuaj yeem ua tiav xoom xoom, tab sis nws lub neej ntev thiab kev hloov pauv kub yog qhov tsis zoo.
Hard seal:
Ob sab ntawm lub sealing khub yog ua los ntawm cov hlau los yog lwm yam ntaub ntawv stiffer, hu ua "hard seals." Hom kev foob no muaj kev ua haujlwm tsis zoo tab sis muaj qhov kub thiab txias tsis kam, abrasive tsis kam, thiab cov khoom siv zoo.
Xws li steel + steel, steel + tooj liab, steel + graphite, thiab steel + alloy steel (cov hlau ntawm no kuj yog cam khwb cia hlau, cam khwb cia hlau, alloy steel, thiab tej zaum surfacing los yog sprayed alloy).
Cov ntsaws ruaj ruaj yog ua los ntawm cov ntaub ntawv hlau thiab muaj kev sib khi tsis zoo, txawm hais tias qee tus neeg tsim khoom thov lawv tuaj yeem ua tiav xoom xoom.
Cov ntsaws ruaj ruaj tsis tuaj yeem ua tau raws li kev ua haujlwm rau qee qhov kev tshaj tawm corrosive, tab sis cov ntsaws ruaj ruaj nyuaj tuaj yeem daws qhov teeb meem! Qhov zoo thiab qhov tsis zoo ntawm ob cov ntaub ntawv sib khi no tuaj yeem them nyiaj rau ib leeg. Nyob rau hauv cov nqe lus ntawm sealing kev ua tau zoo, cov ntsaws ruaj ruaj muag kuj zoo dua, tab sis tam sim no, sealing kev ua tau zoo ntawm cov ntsaws ruaj ruaj tseem tuaj yeem ua tau raws li qhov yuav tsum tau ua!
Qhov kom zoo dua ntawm cov mos mos yog qhov zoo sealing kev ua tau zoo, tab sis qhov tsis zoo yog tias nws yooj yim rau hnub nyoog thiab hnav thiab muaj lub neej ua haujlwm luv luv.
Cov ntsaws ruaj ruaj muaj lub neej ua haujlwm ntev, tab sis lawv cov sealing kev ua tau zoo yog qhov phem dua li cov ntsaws ruaj ruaj.
Lub ntsiab yam ntxwv txawv:
1. Kev sib txawv ntawm cov qauv: Cov npauj npaim muag muag feem ntau yog hom kab nruab nrab; hard-sealed npauj npaim li qub feem ntau yog ib leeg-eccentric, ob-eccentric, lossis triple-eccentric.
2. Temperature resistance: Cov ntsaws ruaj ruaj yog siv nyob rau hauv ib puag ncig kub. Cov ntsaws ruaj ruaj tuaj yeem siv rau hauv qhov qis, nruab nrab, siab, thiab lwm yam.
3. Siab: Cov ntsaws ruaj ruaj yog tsim nyog rau lub siab tsis tshua muaj siab, thiab cov ntsaws ruaj ruaj tseem tuaj yeem siv rau hauv nruab nrab thiab siab-siab. cov
4. Sealing kev ua tau zoo: Kev sealing kev ua tau zoo ntawm cov foob mos thiab triple eccentric nyuaj foob npauj npaim li qub yog qhov zoo dua. Lub triple eccentric npauj npaim valve tuaj yeem tswj tau zoo sealing nyob rau hauv high-pressure thiab high-temperature ib puag ncig.
