Qhov sib txawv ntawm cov qauv ntawm npauj npaim valve distinguishes plaub hom npauj npaim li qub, uas yog:concentric npauj npaim valve, ib leeg eccentric npauj npaim valve,ob chav eccentric npauj npaim valvethiab triple eccentric npauj npaim valve.Lub tswvyim ntawm no eccentricity yog dab tsi?Yuav ua li cas txiav txim siab thaum twg siv concentric npauj npaim valve, thaum twg siv ib qho eccentric npauj npaim valve, thaum twg siv ob chav eccentric npauj npaim valve thiab triple eccentric npauj npaim valve?Ntau tus neeg siv tsis meej tshwj xeeb.Cia peb kawm ua ke.
Concentric npauj npaim li qub, ib leeg eccentric npauj npaim li qub, ob npaugeccentric npauj npaim li qubthiab triple eccentric npauj npaim li qub tau qhia txog cov txheej txheem ntawm kev qhib thiab kaw nrog tsawg dua thiab siv zog tsawg dua thiab tsawg dua hnav ntawm qhov chaw sib khi.Los ntawm kev teeb tsa txoj hauj lwm ntawm lub rotating ncej ntawm npauj npaim valve phaj, lub sealing thiab qhib lub xeev ntawm npauj npaim valve tuaj yeem hloov pauv.Nyob rau hauv tib yam kev mob, lub torque ntawm lub valve thaum qhib yog nce nyob rau hauv ib ntus.Thaum lub valve qhib, lub kaum sab xis uas yuav tsum tau rau lub valve phaj cais los ntawm lub foob yog me dua nyob rau hauv ib ntus.
Cov yam ntxwv ntawm lub concentric npauj npaim valve yog qhov chaw nruab nrab ntawm lub valve qia, qhov nruab nrab ntawm lub phaj npauj npaim thiab qhov nruab nrab ntawm lub cev valve yog nyob rau tib txoj haujlwm.Feem ntau hais lus, yog concentric npauj npaim li qub tuaj yeem siv tau, nws yuav tsum siv ntau li ntau tau.Vim tias hom concentric tsis xav tau kev sib khi ua haujlwm siab ntawm cov qauv lossis kev ua haujlwm, nws yog cov khoom siv sib xyaw.Yuav kom kov yeej extrusion, scraping, thiab xyuas kom meej sealing kev ua tau zoo, lub rooj zaum valve ntawm concentric npauj npaim valve yog tsim los ntawm roj hmab los yog PTFE thiab lwm yam ntaub ntawv elastic, uas yog ib tug mos sealing npauj npaim valve.Qhov no ua rau kev siv concentric npauj npaim li qub raws li qhov kub thiab txias.Yuav kom daws tau qhov teeb meem extrusion ntawm npauj npaim phaj thiab lub rooj zaum valve, ib qho eccentric npauj npaim valve tau tsim.Nws cov yam ntxwv tshwj xeeb yog qhov chaw nruab nrab ntawm lub valve qia deviates los ntawm qhov chaw ntawm npauj npaim phaj.
Ob chav eccentric npauj npaim valve yog qhov siv dav tshaj plaws.Nws cov yam ntxwv tshwj xeeb yog qhov chaw nruab nrab ntawm lub valve qia deviates los ntawm qhov chaw ntawm npauj npaim phaj thiab qhov nruab nrab ntawm lub cev valve.Nws deviates los ntawm ob txoj haujlwm hauv nruab nrab, yog li nws yog hu ua ob chav eccentric npauj npaim valve.Feem ntau ntawm lawv yog kab kaw.Thaum lub sealing nto raug kaw, muaj kev sib txhuam ntawm lub phaj disc thiab lub rooj zaum valve, thiab cov nyhuv sealing zoo heev.Nws muaj cov yam ntxwv ntawm thaj chaw me me thiab muaj zog siab.Tom qab lub valve qhib, lub phaj npauj npaim tuaj yeem tawg tam sim ntawd ntawm lub rooj zaum valve, uas tshem tawm qhov tsis tsim nyog extrusion thiab scraping ntawm lub phaj thiab lub rooj zaum, txo qhov qhib qhov deb, hnav, thiab txhim kho kev pab cuam lub neej ntawm lub rooj zaum valve.
Lub triple eccentric npauj npaim valve muaj qhov thib peb eccentricity ntawm lub hauv paus ntawm ob lub eccentric npauj npaim valve.Cov duab ntawm lub sealing khub tsis yog lub khob zoo, tab sis lub khob hliav qab oblique.Feem ntau ntawm lawv yog luv luv quab yuam thiab nto foob.Lub qia ncej ntawm triple eccentric npauj npaim valve yog peb ntu ncej qauv.Ob lub ncej ntawm peb-seem ncej valve qia yog concentric, thiab qhov nruab nrab ntawm qhov nruab nrab ncej ncej deviates ntawm lub axis ntawm ob kawg los ntawm ib qho chaw nyob deb, thiab tus npauj npaim phaj yog nruab rau hauv nruab nrab.ntawm tus ncej.Xws li cov qauv eccentric ua rau npauj npaim phaj ob lub ntsej muag eccentric thaum nws qhib tag nrho, thiab ib qho eccentric zoo li thaum npauj npaim phaj tig mus rau qhov chaw kaw.Vim yog cov nyhuv ntawm eccentric ncej, thaum nws nyob ze rau kaw, npauj npaim phaj txav mus deb ntawm lub sealing cone nto ntawm lub rooj zaum valve, thiab tus npauj npaim phaj phim lub sealing nto ntawm lub rooj zaum valve kom ua tiav kev sealing zoo.Nws ua rau qhov tsis sib haum xeeb tias lub foob tawv tawv muaj lub foob tsis zoo, thiab cov foob mos muag muaj qhov sib khi zoo tab sis tsis tiv taus qhov kub thiab txias.
Thaum twg siv lub concentric npauj npaim valve, thaum xaiv ob chav eccentric npauj npaim valve lossis triple eccentric npauj npaim valve, feem ntau yog nyob ntawm kev ua haujlwm thiab nyiaj txiag.
