1.Centerline npauj npaim valvethiab eccentric npauj npaim valve
Centerline npauj npaim valve thiab eccentric npauj npaim valve muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, Thaum xaiv tus qauv, nws yuav tsum tau txiav txim siab ua ke nrog nws cov nqi ua haujlwm.Feem ntau hais lus, qhov nruab nrab kab npauj npaim valve yog pheej yig dua li eccentric npauj npaim valve.Centerline npauj npaim li qub yog dav siv nyob rau hauv kuv lub teb chaws lub me-inch npauj npaim li qub, thiab cov nyhuv kuj zoo.Nws lub foob kaw yog qhov tseem ceeb ntawm cov roj hmab hauv ob sab phlu nyem foob, tshwj xeeb tshaj yog nyob ze ntawm lub valve ncej yog ntau nyem, kom lub neej kev pab cuam ntawm lub valve raug cuam tshuam, thiab qhib thiab kaw torque ntawm lub valve yog loj heev.Txhawm rau txo qhov tsis txaus ntawm qhov no, eccentric npauj npaim valve tshwm sim.Lub theoretical sealing xeev yog lub xeev kev sib cuag.Ntau manufacturers tau tsim qhov nam no.Lub eccentric npauj npaim valve yog kev taw qhia hauv kev coj tus kheej dej siab, tshwj xeeb tshaj yog peb-dimensional eccentric npauj npaim valve.Qhov rov qab siab bearing muaj peev xwm tsis muaj zog.Vim hais tias cov yeeb nkab network yog lub nplhaib-puab, qhov yuav tsum tau rau lub valve kom dais siab nyob rau hauv ob qho tib si cov lus qhia yog tib yam, yog li qhov yuav tsum tau yuav tsum tau hais txog thaum xaiv lub valve.
2.Vertical thiab kab rov tav npauj npaim li qub
Hauv nruab nrab thiab loj npauj npaim li qub, muaj qhov sib txawv ntawm ntsug thiab kab rov tav valve shafts.Feem ntau, ntsug npauj npaim li qub yog npog nrog cov av sib sib zog nqus, thiab cov khib nyiab hauv cov dej zoo li yuav qhwv ib ncig ntawm cov ncej kawg thiab cuam tshuam rau qhov qhib thiab kaw;qhov sib txawv ntawm qhov sib kis ceev ntawm kab rov tav npauj npaim li qub yog nyob rau sab.Lub valve zoo nyob hauv txoj haujlwm dav dav ntawm txoj kev, uas cuam tshuam rau kev teeb tsa ntawm lwm cov kav dej.Yog li ntawd, nyob rau hauv kev pom ntawm cov teeb meem saum toj no, nws yuav tsum tau meej meej nyob rau hauv cov txheej txheem xaiv valve: nruab nrab-inch npauj npaim li qub feem ntau yog ntsug, thiab loj-inch npauj npaim li qub yuav tsum xub ua kab rov tav yog tias qhov xwm txheej ntawm txoj haujlwm dav hlau tau tso cai.Qhov no tsis tsuas yog txhim kho cov dej ntws ntawm lub valve, tab sis kuj daws qhov teeb meem ntawm sundries nyob rau hauv cov dej entangled nrog lub valve ncej.
3.Soft foob thiab hlau foob.
Feem ntau ntawm cov npauj npaim li qub siv hauv kev lag luam dej yogsoft-sealed npauj npaim li qub.Vim muaj qee qhov teeb meem hauv kev siv txoj kev sib khi no, ntau lub tuam txhab tau qhia cov hlau nplaum npauj npaim li qub los hloov cov roj hmab-sealed butterfly li qub.Thaum peb xaiv cov foob mos thiab hlau foob li qub, peb tseem yuav tsum tau xav txog cov nqi-zoo ntawm ob.
① Cov teeb meem tseem ceeb ntawm kev siv lub ntsej muag npauj npaim valve yog: cov roj hmab tsis zoo, lub hnub nyoog yooj yim, lub sij hawm ntev compression deformation, thiab extrusion tawg.Yog li ntawd, qee cov tuam ntxhab feem ntau xaiv EPDM roj hmab thiab cov roj hmab nitrile thiab siv cov roj hmab ntuj me me.Nws yog nruj me ntsis txwv tsis pub muab cov roj hmab rov qab los txhim kho qhov hnav tsis kam thiab kev laus ua haujlwm ntawm lub nplhaib sealing.
② Cov hlau nplaum npauj npaim valve feem ntau siv cov qauv eccentric, tshwj xeeb tshaj yog cov qauv eccentric peb sab, vim qhov me me elasticity ntawm lub foob.Cov hlau-sealed npauj npaim valve yog Ameslikas siv nyob rau hauv high-pressure steam pipelines, thiab tus nqi kuj kim heev.Nws lub sealing nto tsis yooj yim rau kev puas tsuaj thaum lub sijhawm ua haujlwm, tab sis nws cov khoom raug siab, thiab thaum nws ntws tawm, nws nyuaj rau kho.
