Dab tsi yog cov teeb meem thiab kev daws teeb meem rau npauj npaim li qub thaum siv?
Npauj npaim valve vim nws qhov me me thiab cov qauv yooj yim, tau dhau los ua ib qho ntawm feem ntau siv li qub nyob rau hauv kev lag luam, ntau thiab ntau tau siv rau hydroelectric zog, irrigation, lub tsev dej mov thiab kua, municipal engineering thiab lwm yam piping systems, siv rau txiav tawm los yog kho kom haum cov circulating media flow mus siv. Tom qab ntawd npauj npaim valve hauv kev siv cov teeb meem uas xav tau kev saib xyuas thiab kev daws teeb meem rau dab tsi, hnub no peb yuav qhia tshwj xeeb kom nkag siab.
Npauj npaim valve installation tseem ceeb yuav tsum tau saib xyuas:
1.Ua ntej installation, thov paub meej tias cov khoom ua tau zoo thiab cov ntawv xov xwm ntws tau zoo ib yam nrog kev txav ntawm kev ua haujlwm, thiab yuav yog lub valve kab noj hniav ntxuav, tsis txhob cia impurities nyob rau hauv lub sealing nplhaib thiab npauj npaim phaj txuas nrog cov khoom txawv teb chaws, tsis ntxuav ua ntej los ntawm tsis muaj txhais tau tias tso cai rau kaw lub phaj npauj npaim, thiaj li tsis ua kom puas lub nplhaib sealing.
2.Disc phaj installation txhawb flange yog pom zoo kom siv tshwj xeeb flange npauj npaim valve.
3.Installed nyob rau hauv nruab nrab ntawm lub raj xa dej los yog txoj hauj lwm ntawm ob qhov kawg ntawm lub raj xa dej, txoj hauj lwm zoo tshaj plaws rau kev teeb tsa ntsug, tsis tuaj yeem ntsia tau rov qab.
4. Kev siv cov kev xav tau los tswj cov dej ntws, muaj cov phau ntawv, hluav taws xob, pneumatic actuators rau kev tswj.
5. Qhib thiab kaw ntau zaus npauj npaim valve, nyob rau hauv li ntawm ob lub hlis, yuav tsum tau qhib lub thawv iav npog npog, xyuas seb lub butter puas zoo li qub, yuav tsum khaws cov butter kom zoo.
6.Kuaj xyuas seb qhov txuas txuas puas raug nias, uas yog, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txuas yog nias lub pob sib txuas.
7.Metal seal npauj npaim valve cov khoom tsis haum rau kev teeb tsa ntawm qhov kawg ntawm lub raj xa dej, xws li yuav tsum tau muab tso rau ntawm qhov kawg ntawm cov kav dej, koj yuav tsum nqa lub qhov hluav taws xob haum flange, txhawm rau tiv thaiv lub nplhaib sealing ntawm lub siab, dhau. txoj hauj lwm.
8.Lub valve qia kev teeb tsa thiab siv cov lus teb kom tsis tu ncua xyuas cov txiaj ntsig ntawm lub valve, pom muaj qhov tsis raug raws sijhawm.
Tej yam ua rau tsis ua hauj lwm: sealing nto to
1.Valve phaj, sealing deg nplaub tshev khib nyiab
2.Valve phaj, sealing nto kaw txoj hauj lwm coincide nrog tsis raug
3.Outlet sab configuration mounting flange bolts tsis sib npaug zog los yog xoob bolts
4.Pressure test kev taw qhia tsis yog raws li qhov yuav tsum tau ntawm qhov nruab nrab ntws kev taw qhia.
Txoj kev tshem tawm
1. Tshem tawm impurities, ntxuav lub puab kab noj hniav ntawm lub valve
2. Kho cov cab iav los yog hluav taws xob, pneumatic actuator kho cov ntsia hlau kom ua tiav txoj haujlwm raug ntawm lub valve kaw
3.Kuaj xyuas lub dav hlau haum flange thiab ntsia liaj qhov rooj compression fastening, yuav tsum tau sib npaug compressed
4.Raws li tus xub sealing kev taw qhia rau siab
Valve ob kawg to tsis ua hauj lwm ua rau
1.Ob sab ntawm lub sealing gasket tsis ua hauj lwm
2. Cov yeeb nkab flange nruj tsis sib xws los yog tsis compressed
3.Sealing nplhaib los yog sealing nplhaib nyob rau hauv lub gasket tsis ua hauj lwm
Txoj kev tshem tawm
1. Hloov lub sealing gasket
2.Pressure flange bolts (lub cev muaj zog)
3. Tshem tawm lub valve siab nplhaib, hloov lub nplhaib sealing thiab tsis ua hauj lwm ntawm lub gasket.
Npauj npaim valve tuaj yeem muab faib rau hauv nruab nrab kab npauj npaim valve thiab eccentric npauj npaim valve raws li daim ntawv qauv. Raws li daim ntawv sealing tuaj yeem muab faib ua hom mos mos thiab tawv foob hom. Hom kev sib khi mos feem ntau siv roj hmab lub rooj zaum lossis roj hmab nplhaib sealing, nyuaj sealing hom feem ntau yog siv hlau nplhaib sealing. Raws li hom kev sib txuas, nws tuaj yeem muab faib ua flange kev twb kev txuas thiab wafer txuas; Raws li hom kev sib kis, nws tuaj yeem muab faib ua phau ntawv, hluav taws xob, pneumatic thiab hydraulic. Peb tuaj yeem xaiv cov actuators sib txawv raws li kev ua haujlwm.
