Niaj hnub no peb tseem tham txog kev ceev faj txog kev teeb tsa valve:
Taboo 12
Cov kev qhia tshwj xeeb thiab cov qauv ntawm lub valve ntsia tsis tau raws li cov qauv tsim.
Piv txwv li, lub nominal siab ntawm lub valve yog tsawg tshaj li qhov system xeem siab;lub rooj vag valve rau pub dej ceg yeeb nkab thaum cov yeeb nkab txoj kab uas hla yog tsawg dua los yog sib npaug li 50 hli;qhuav thiab risers rau cov dej kub cua sov;thiab qhov hluav taws kub twj tso kua mis suction yeeb nkab adoptsnpauj npaim valve.
Cov txiaj ntsig: cuam tshuam rau qhov qub qhib thiab kaw ntawm lub valve thiab kho qhov tsis kam, siab thiab lwm yam haujlwm.Txawm tias ua rau lub cev ua haujlwm, lub valve puas raug yuam kom kho.
Kev ntsuas: Paub txog daim ntawv thov ntawm ntau yam li qub, thiab xaiv cov kev qhia tshwj xeeb thiab cov qauv ntawm cov li qub raws li cov qauv tsim.Lub nominal siab ntawm lub valve yuav tsum ua tau raws li qhov yuav tsum tau ntawm lub kaw lus ntsuas siab.Raws li txoj cai kev tsim kho: nres valve yuav tsum tau siv thaum cov yeeb nkab txoj kab uas hla yog tsawg dua los yog sib npaug li 50 hli;Lub rooj vag valve yuav tsum tau siv thaum lub yeeb nkab txoj kab uas hla yog ntau tshaj 50mm.Cov dej kub cua sov kom qhuav, ntsug tswj valve yuav tsum tau siv lub rooj vag valve, hluav taws kub twj tso kua mis suction yeeb nkab yuav tsum tsis txhob siv npauj npaim valve.

Cov ntaub ntawv tseem ceeb, cov cuab yeej siv thiab cov khoom siv hauv kev tsim kho tsis muaj cov ntaub ntawv pov thawj zoo lossis cov ntawv pov thawj cov khoom uas ua tau raws li lub teb chaws tam sim no lossis cov qauv kev cai lij choj.
Qhov tshwm sim: tsis tsim nyog qhov project zoo, muaj peev xwm raug xwm txheej, tsis tuaj yeem xa tuaj raws sijhawm, yuav tsum rov ua dua thiab kho dua tshiab;ua rau kev tsim kho qeeb thiab nce kev ua haujlwm thiab cov khoom siv nkag.
Kev ntsuas: Cov ntaub ntawv tseem ceeb, cov khoom siv thiab cov khoom siv hauv cov dej thiab cov cua sov yuav tsum muaj cov ntaub ntawv ntsuas kev ua haujlwm zoo lossis cov ntawv pov thawj cov khoom ua raws li cov qauv tam sim no los ntawm lub xeev lossis Ministry;lub caij no, cov khoom npe, qauv, specification, lub teb chaws zoo tus qauv code, hnub yug, chaw tsim tshuaj paus npe thiab qhov chaw, soj ntsuam daim ntawv pov thawj los yog code yuav tsum tau qhia.
Taboo 14
Valve inverted
Qhov tshwm sim: kos lub valve, lub valve valve, lub siab txo lub valve, kos valve thiab lwm yam li qub muaj cov kev taw qhia, yog tias ntsia tau rov qab, lub throttle valve yuav cuam tshuam rau kev pabcuam thiab lub neej;Lub siab txo valve tsis ua hauj lwm tag nrho, lub check valve yuav ua rau muaj kev phom sij.
Kev ntsuas: dav dav valve, nrog kev taw qhia kos npe rau ntawm lub cev valve;Yog tias tsis yog, yuav tsum raug txheeb xyuas raws li txoj cai ua haujlwm ntawm lub valve.Lub valve kab noj hniav ntawm qhov nres valve yog asymmetric, cov kua yuav tsum cia nws dhau los ntawm lub qhov ncauj valve los ntawm hauv qab mus rau sab saum toj, kom cov dej tsis kam yog me me (txiav txim siab los ntawm cov duab), qhib kev txuag nyiaj (vim qhov nruab nrab siab. up), kaw qhov nruab nrab tsis txhob nias lub ntim, yooj yim txij nkawm.Qhov no yog vim li cas qhov nres valve tsis tuaj yeem daws tau.
Taboo 15
Lub valve tsis ua cov rwb thaiv tsev kub thiab txias ntsuas
Kev ntsuas: qee qhov li qub yuav tsum muaj cov chaw tiv thaiv sab nraud, qhov no yog thermal rwb thaiv tsev thiab kev tiv thaiv txias.Thermal rwb thaiv tsev chav pipeline yog qee zaum ntxiv rau txheej rwb thaiv tsev.Dab tsi ntawm valve yuav tsum tau insulated los yog txias, raws li qhov yuav tsum tau ua.Raws li txoj cai, qhov nruab nrab hauv lub valve txo qhov kub thiab txias ntau dhau, yuav cuam tshuam rau kev tsim khoom lossis khov lub valve, nws xav tau kev rwb thaiv tsev, txawm tias cua sov tracing;qhov twg lub valve raug, tsis zoo rau ntau lawm los yog ua rau Frost thiab lwm yam adverse tshwm sim, nws yog tsim nyog los ua kom txias.Cov ntaub ntawv thermal rwb thaiv tsev muaj xws li asbestos, slag paj rwb, iav ntaub plaub, perlite, diatom av, vermiculite;Cov khoom siv tiv thaiv txias muaj xws li cork, perlite, ua npuas ncauj, yas, thiab lwm yam.
Taboo 16
Lub valve tsis tau ntsia los ntawm bypass
Kev ntsuas: qee qhov li qub, ntxiv rau cov chaw tiv thaiv tsim nyog, tab sis kuj tseem muaj kev hla thiab ntsuas.Lub bypass yog ntsia los pab txhim kho cov cuab yeej dej.Lwm yam li qub, kuj tau nruab bypass.Seb puas yuav nruab bypass yog nyob ntawm qhov xwm txheej ntawm lub valve, qhov tseem ceeb thiab kev tsim khoom yuav tsum tau ua.
Taboo 17
Lub muab tub lim tsis hloov tsis tu ncua
Kev ntsuas: cov khoom lag luam valve, qee qhov muab tub lim tsis zoo, qee qhov tsis ua raws li kev siv xov xwm, uas yuav tsum tau hloov cov muab tub lim.
Lub valve ntsib ntau txhiab yam ntawm cov xov xwm sib txawv, thiab daim ntawv sau yog ib txwm sau nrog cov hauv paus hniav zoo tib yam, tab sis thaum siv, cov ntim yuav tsum tau hloov mus rau qhov nruab nrab.
Thaum hloov cov muab tub lim, nias nws nyob rau hauv ib puag ncig thiab puag ncig.Txhua lub puab tsaig yog 45 degrees, thiab lub nplhaib thiab lub nplhaib sib koom yog 180 degrees.Qhov siab ntawm cov ntim yuav tsum xav txog chav tsev rau kev txuas ntxiv ntawm lub hau, thiab tam sim no, qhov qis ntawm lub hau yuav tsum muaj qhov tob uas tsim nyog, uas feem ntau tuaj yeem yog 10-20% ntawm tag nrho qhov tob ntawm lub ntim chamber.
Dhau li ntawd, Tianjin Tanggu Dej Foob Valve Co., Ltd. yog ib tug technologically advanced elastic rooj valve txhawb kev lag luam, cov khoom yog elastic rooj zaum wafer npauj npaim valve,lug npauj npaim valve,ob flange concentric npauj npaim valve, ob flangeeccentric npauj npaim valve, balance valve,wafer dual phaj kos valve, Y-Strainer thiab lwm yam.Ntawm Tianjin Tanggu Dej Foob Valve Co., Ltd., peb txaus siab rau peb tus kheej ntawm kev muab cov khoom lag luam thawj zaug uas ua tau raws li cov qauv kev lag luam siab tshaj plaws.Nrog peb ntau yam ntawm li qub thiab fittings, koj tuaj yeem tso siab rau peb los muab cov kev daws teeb meem zoo tshaj plaws rau koj qhov system dej.Tiv tauj peb hnub no kom paub ntau ntxiv txog peb cov khoom thiab peb tuaj yeem pab koj li cas.
