Npauj npaim valve tseem hu ua nrov plig plawg valve, yog cov qauv yooj yim ntawm kev tswj lub valve, tab sis kuj tuaj yeem siv rau kev siv hluav taws xob qis qis nruab nrab hloov tswj. Npauj npaim valve yog hais txog ib hom valve uas nws kaw qhov (disc lossis disc) yog lub disc, uas tig ib ncig ntawm lub valve kom qhib thiab kaw. Nws tsuas yog ua lub luag haujlwm ntawm kev txiav tawm thiab throttling ntawm cov kav dej. Qhov qhib thiab kaw ib feem ntawm npauj npaim valve yog lub phaj zoo li npauj npaim disc, uas tig ib ncig ntawm nws tus kheej axis hauv lub cev valve, thiaj li ua tiav lub hom phiaj ntawm kev qhib thiab kaw lossis kho. Npauj npaim valve siv tau rau cov raj xa dej xa tawm ntau yam corrosive thiab tsis corrosive fluid media hauv lub tshuab hluav taws xob, roj, roj av, roj av roj, lub nroog roj, cua txias thiab kub, tshuaj smelting thiab hluav taws xob tsim thiab kev tiv thaiv ib puag ncig engineering, uas yog siv los ua tswj thiab txiav tawm qhov ntws ntawm nruab nrab.
Kev siv npauj npaim valve
Npauj npaim li qub yog tsim rau kev khiav dej num. Txij li thaum lub siab poob ntawm npauj npaim valve hauv lub raj xa dej yog qhov loj, uas yog kwv yees li peb zaug ntawm lub rooj vag valve, qhov cuam tshuam ntawm kev poob siab ntawm cov kav dej yuav tsum tau txiav txim siab thaum xaiv npauj npaim valve, thiab qhov ruaj khov ntawm npauj npaim phaj bearing pipeline. nruab nrab siab thaum kaw yuav tsum tau txiav txim siab. Tsis tas li ntawd, kev ua haujlwm kub txwv ntawm cov khoom siv lub rooj zaum ntawm qhov kub siab yuav tsum raug txiav txim siab.
Tus qauv ntev thiab tag nrho qhov siab ntawm npauj npaim valve yog me me, qhov qhib thiab kaw ceev yog ceev, thiab nws muaj cov yam ntxwv zoo tswj cov dej. Cov qauv hauv paus ntsiab lus ntawm npauj npaim valve yog qhov tsim nyog tshaj plaws rau kev ua lub taub loj loj. Thaum npauj npaim valve yuav tsum tau siv rau kev tswj ntws, qhov tseem ceeb tshaj plaws yog xaiv qhov loj thiab hom npauj npaim valve, kom nws tuaj yeem ua haujlwm tau zoo thiab zoo.
Feem ntau, nyob rau hauv throttling, regulating tswj thiab av nkos nruab nrab, luv qauv ntev thiab ceev qhib thiab kaw ceev (1 / 4R) yuav tsum tau. Tsis tshua muaj siab txiav-tawm (qhov sib txawv me me), npauj npaim valve raug pom zoo.
Npauj npaim valve tuaj yeem siv tau thaum muab ob npaug rau txoj haujlwm hloov, kev cog lus channel, tsis tshua muaj suab nrov, cavitation thiab gasification tshwm sim, ib qho me me ntawm cov pa tawm mus rau qhov chaw, thiab nruab nrab abrasive.
Thaum lub npauj npaim valve siv nyob rau hauv tshwj xeeb kev ua hauj lwm, xws li throttling kev cai, nruj sealing, hnyav hnyav thiab tsis kub (tso txias), tshwj xeeb npauj npaim valve nrog tshwj xeeb tsim hlau sealing siv regulating ntaus ntawv yuav tsum tau siv.
Qhov nruab nrab kab npauj npaim valve yog tsim rau cov dej tshiab, dej phwj tuaj, dej hiav txwv, dej ntsev, chav, nkev, khoom noj, tshuaj, roj thiab ntau yam kua qaub-puag thiab lwm yam kav dej uas yuav tsum tau ua kom tiav sealing, xoom gas test to, siab lub neej yuav tsum. , thiab ua haujlwm kub ntawm -10 ~ 150 ℃.
Nws yog dav siv hauv metallurgy, lub teeb kev lag luam, hluav taws xob fais fab, petrochemical system gas pipeline thiab dej channel.
Hlau rau hlau hlau kaw ob chav eccentric npauj npaim valve yog tsim rau lub nroog tshav kub, chav mov, dej thiab roj, roj, kua qaub thiab alkali pipelines raws li regulating thiab intercepting li.
Hlau rau hlau foob triple eccentric npauj npaim valve tsis yog tsuas yog siv raws li kev tswj hwm lub valve ntawm lub siab viav vias adsorption (PSA) roj cais tawm, tab sis kuj siv dav hauv roj av, petrochemical, tshuaj, metallurgy, hluav taws xob thiab lwm yam haujlwm. Nws yog ib qho zoo hloov rau lub rooj vag valve thiab nres valve.
Xaiv txoj cai ntawm npauj npaim valve
1. Muab piv nrog lub rooj vag valve, lub siab poob ntawm npauj npaim valve yog qhov loj dua, yog li nws tsim nyog rau cov kav dej uas tsis muaj qhov yuav tsum tau ua.
2. Txij li thaum npauj npaim valve tuaj yeem hloov kho los ntawm kev ntws, nws yog qhov tsim nyog los xaiv rau hauv cov kav dej uas xav tau kev khiav dej num.
3. Vim qhov kev txwv ntawm cov qauv thiab cov khoom sib khi ntawm npauj npaim valve, nws tsis haum rau qhov kub thiab txias thiab kub siab pipeline system. Qhov kev ua haujlwm dav dav yog qis dua 300 ℃ thiab qhov nominal siab yog qis dua PN40.
4. Raws li tus npauj npaim valve qauv ntev yog luv luv, thiab tuaj yeem ua rau hauv txoj kab uas hla loj, yog li nyob rau hauv cov ntaub ntawv ntawm cov qauv luv luv lossis loj txoj kab uas hla valve (xws li ntau tshaj DN 1000), npauj npaim valve yuav tsum tau xaiv.
5. Txij li thaum npauj npaim valve tuaj yeem qhib lossis kaw tsuas yog los ntawm 90 ° kev sib hloov, nws yog qhov tsim nyog los xaiv cov npauj npaim valve hauv thaj teb uas yuav tsum tau qhib thiab kaw.
