Npauj npaim li qub siv feem ntau siv li qub nyob rau hauv cov tshuab dej. Lawv yog cov li qub nrog cov nqi ua tau zoo thiab dhau los ua qhov qub rau cov kav xa dej. Cov khoom tseem ceeb ntawm npauj npaim li qub yog clamped muag muag npauj npaim li qub thiab flanged npauj npaim li qub. Txawm hais tias npauj npaim li qub tsawg dua li rooj vag li qub, muaj ntau qhov sib txawv ntawm lawv kom haum rau cov xwm txheej sib txawv. Tshooj lus no Shanghai npauj npaim valve chaw tsim tshuaj paus - Shanghai zeb valve yuav nug koj kom paub npauj npaim valve kev ua tau zoo, npauj npaim valve qauv, npauj npaim valve qauv, npauj npaim valve kev faib tawm, kom pab koj zoo dua nqa npauj npaim valve xaiv.
Npauj npaim valve kaw - npauj npaim phaj yog disc zoo li tus kheej, tig ib ncig ntawm lub qag qhov rooj ntawm lub rooj zaum 90 degrees tuaj yeem pib thiab kaw thiab kho qhov nruab nrab. Nws yog dav siv nyob rau hauv nruab nrab thiab qis siab loj caliber pipelines. Cov qauv ntawm npauj npaim valve yog pom tias muaj.
1, kev faib tawm ntawm npauj npaim li qub:
Raws li cov qauv kev faib tawm, npauj npaim li qub tau muab faib ua nruab nrab thiab eccentric, suav nrog eccentric, eccentric, ob chav eccentric thiab peb eccentric npauj npaim li qub.
Muaj feem rau npauj npaim valve khoom: clip npauj npaim valve, teeb liab npauj npaim valve, flange npauj npaim valve, loj txoj kab uas hla flange npauj npaim valve thiab li ntawm.
2, cov qauv kev ua tau zoo ntawm npauj npaim valve
Npauj npaim valve siv lub pob valve raws qhov nruab nrab ntawm kev sib hloov qauv, yog li ntawd lub valve me me. Los ntawm tig tus kov 90 degrees los yog lub vauj log thiab lwm hom kev tsav tsheb, lub phaj valve thiab nruab nrab ntws kev taw qhia tib si tuaj yeem qhib lub valve. Yog li no, npauj npaim valve muaj cov yam ntxwv ntawm cov qauv yooj yim, me me, lub teeb yuag, kev teeb tsa me me, kev lag luam yooj yim thiab kev qhib nrawm thiab kaw. Nyob rau tib lub sijhawm, nws tseem muaj cov yam ntxwv ntawm kev khi thiab ntws kev tswj. Txawm li cas los xij, vim muaj qhov loj ntawm disc, nruab nrab lub siab muaj qhov cuam tshuam loj ntawm kev qhib valve thiab kaw, yog li nws tsis haum rau qhov chaw siab hloov siab.
Cov qub npauj npaim valve tau txwv los ntawm cov thev naus laus zis thiab cov khoom sib khi, feem ntau ntawm cov qauv yog nruab nrab thiab cov kab muag muag muag, uas yog, lub rooj zaum feem ntau yog roj hmab, yas, npauj npaim phaj li hlau lossis hlau coated roj hmab lossis yas. Nyob rau hauv xyoo tas los no, nrog txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, npauj npaim valve tau tsim txoj kev qauv tshiab. Lub eccentric hlau muab npauj npaim valve yog ib qho ntawm lawv. Lub puab tsaig lub rooj zaum thiab npauj npaim phaj foob lub ntsej muag ntawm eccentric hlau foob yog tsim los ntawm cov khoom siv hlau cemented carbide, lossis npauj npaim phaj yog ua los ntawm cov khoom muag muag thiab tawv (tsis yog hlau txheej clip hlau txheej). Tus npauj npaim valve tuaj yeem tiv taus qhov kub thiab txias, tsis tshua muaj kub tsis kam, tsis kam tiv taus, yaig tsis kam, ua haujlwm zoo sealing thiab kev pab lub neej ntev, yog li nws tau siv dav.
Npauj npaim li qub tau hloov lub rooj vag li qub, ntiaj teb li qub, lub qhov ncauj qhib lub pob thiab lub pob hauv pob ntau yam. Lawv yog ib qho ntawm cov khoom siv ntau yam uas tau loj hlob sai heev nyob rau hauv xyoo tas los no.
(1) kev sib piv kev ua tau zoo ntawm npauj npaim valve:
Cov kev ua tau zoo ntawm npauj npaim valve yog qhov tseem ceeb hauv cov ntim me me, cov qauv yooj yim, qhib sai thiab kaw ntawm peb lub ntsiab lus no, qhov tsis zoo kuj pom tseeb tias lub siab poob ntawm cov yeeb nkab ntws nruab nrab yog qhov loj, thiab lub siab qhov chaw siab yog qhov nyuaj. qhib thiab kaw.
(2) tus qauv sib txawv ntawm npauj npaim valve kev faib tawm thiab qhov sib txawv:
Kev sib khi ua tiav ntawm nruab nrab kab npauj npaim valve, ib qho eccentric npauj npaim valve, ob chav eccentric npauj npaim valve thiab peb eccentric npauj npaim valve tau nce ntau ntxiv, thiab lub neej ncua tseem nce nyob rau hauv lem, tab sis tus qauv nyuaj dua thiab tus nqi nce ntxiv. Yog li ntawd, tshwj tsis yog muaj cov kev cai tshwj xeeb, nws feem ntau pheej yig dua thiab haum rau npauj npaim li qub.
