Taw qhia ntawm npauj npaim valve

Npauj npaim valve, tseem hu ua nrov plig plawg valve, yog ib qho yooj yim regulating valve, uas kuj yuav siv tau rau on-off tswj ntawm tsawg-pressure pipeline nruab nrab. Npauj npaim valve yog ib hom valve uas nws kaw qhov (disc los yog npauj npaim phaj) yog ib tug disc thiab tig ib ncig ntawm lub valve axis kom qhib thiab kaw. Nws tsuas yog ua lub luag haujlwm ntawm kev txiav tawm thiab throttling hauv 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 hloov kho. Npauj npaim valve siv tau rau cov raj xa dej xa tawm ntau yam corrosive thiab tsis corrosive kua nruab nrab nyob rau hauv engineering system ntawm generator, gas, natural gas, liquefied petroleum gas, lub nroog gas, cua txias thiab kub, tshuaj smelting, hluav taws xob tsim thiab kev tiv thaiv ib puag ncig. Nws yog siv los tswj thiab txiav tawm qhov ntws ntawm qhov nruab nrab. Daim ntawv thov ntawm npauj npaim valve Npauj npaim valve yog tsim rau kev tswj kev khiav. Raws li lub siab poob ntawm npauj npaim valve hauv cov raj xa dej yog qhov loj, uas yog kwv yees li peb zaug ntawm lub rooj vag valve, thaum xaiv npauj npaim valve, kev cuam tshuam ntawm kev poob siab ntawm cov kav dej yuav tsum tau txiav txim siab tag nrho, thiab kev 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. Lub npauj npaim valve muaj qhov zoo ntawm cov qauv me me ntev thiab qhov siab tag nrho, qhib thiab kaw nrawm, thiab cov yam ntxwv tswj cov dej zoo. Lub hauv paus ntsiab lus ntawm tus npauj npaim valve yog qhov tsim nyog tshaj plaws rau kev ua lub taub loj loj. Thaum npauj npaim valve yuav tsum tau tswj qhov ntws, qhov tseem ceeb tshaj plaws yog xaiv qhov loj thiab hom npauj npaim valve kom 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) yog yuav tsum tau. Tsis tshua muaj siab txiav-tawm (tsis tshua muaj siab sib txawv), npauj npaim valve yog pom zoo. Npauj npaim valve yuav siv tau nyob rau hauv ob txoj hauj lwm hloov, necking channel, tsis tshua muaj suab nrov, cavitation thiab gasification, ib tug me me npaum li cas ntawm leakage rau cua thiab abrasive nruab nrab. Thaum siv npauj npaim valve nyob rau hauv tshwj xeeb ua hauj lwm tej yam kev mob, xws li throttling kev cai, nruj sealing yuav tsum tau, hnyav hnyav, tsis tshua muaj kub (cryogenic), thiab lwm yam, tshwj xeeb tri eccentric los yog Bi eccentric npauj npaim valve nrog tshwj xeeb tsim hlau sealing ntaus ntawv yuav tsum tau. Qhov nruab nrab kab npauj npaim valve yog tsim rau cov dej tshiab, dej phwj tuaj, dej hiav txwv, brine, chav, nkev, cov khoom noj, tshuaj, roj, ntau cov kua qaub thiab cov hauv paus thiab lwm cov kav dej uas yuav tsum tau ua kom tiav sealing, xoom xau hauv kev sim roj, kev ua haujlwm siab. thiab ua haujlwm kub ntawm -10 ~ 150 ℃. Mos foob eccentric npauj npaim valve yog tsim rau bidirectional qhib thiab kaw thiab kho qhov cua thiab plua plav tshem tawm pipeline. Nws yog dav siv nyob rau hauv gas pipeline thiab dej channel ntawm metallurgy, lub teeb kev lag luam, hluav taws xob fais fab thiab petrochemical system. Hlau rau hlau hlau kaw ob chav eccentric npauj npaim valve yog tsim rau hauv nroog cua sov, chav dej, dej thiab roj, roj, kua qaub thiab alkali pipelines, raws li regulating thiab intercepting li. Hlau rau hlau lub ntsej muag kaw triple eccentric npauj npaim valve tuaj yeem siv dav hauv roj av, petrochemical, tshuaj lom neeg, metallurgy, hluav taws xob fais fab thiab lwm yam kev lag luam ntxiv rau kev siv raws li kev tswj hwm valve ntawm PSA loj cais chav tsev. Nws yog ib qho zoo hloov rau lub rooj vag valve thiab nres valve. Kev xaiv lub hauv paus ntsiab lus ntawm npauj npaim valve 1. Piv nrog lub rooj vag valve, npauj npaim valve muaj qhov poob siab loj dua, yog li nws yog qhov tsim nyog rau cov kav dej nrog lax siab poob qhov yuav tsum tau 2. Raws li tus npauj npaim valve tuaj yeem siv rau kev khiav dej num, nws tsim nyog xaiv. nyob rau hauv cov raj xa dej uas xav tau kev khiav dej num 3. Vim yog qhov kev txwv ntawm npauj npaim valve qauv thiab cov khoom sib khi, nws tsis haum rau qhov kub thiab txias thiab siab siab pipeline system. Feem ntau, kev ua haujlwm kub yog qis dua 300 ℃ thiab qhov nominal siab yog qis dua PN40. 4. Vim hais tias 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 ntev yuav tsum tau lossis loj txoj kab uas hla valve (xws li ntau tshaj DN 1000), npauj npaim valve yuav tsum tau xaiv. 5. Vim tias npauj npaim valve tuaj yeem qhib lossis kaw tsuas yog los ntawm 90 ° kev sib hloov, nws tsim nyog siv npauj npaim valve nyob rau hauv qhov chaw uas yuav tsum tau qhib thiab kaw ceev.
