Vim li cas siv pob valve nrog ntws?

Lub pob dej ntws ntws ntwsle valve ntxiv cov dej ntws ntawm cov khoom sib tsoo thiab cov teeb meem tseem ceeb ntawm cov tub ntxhais kawm ua haujlwm, txij nkawm kev phom sij thiab kev nyab xeeb thiab kev nyab xeeb thiab kev phom sij thiab kev nyab xeeb. Lawv yog tshwj xeeb tsis yog siv rau hauv cov ntawv thov nrog cov kev xav tau siab, tshwj xeeb kev ua haujlwm tshwj xeeb lossis kev ua haujlwm nyuaj. Ntawm no yog cov ncauj lus kom ntxaws txheeb xyuas ntawm nws cov kev xav tau thiab qhov zoo:
I. Cov kev xav tau: hais txog peb qhov kev phom sij ntawm Media Letention
Kev Nyab Xeeb Kev Nyab Xeeb
Mob: Thaum cov zaub mov thiab kev lag luam muag khoom siv hluav taws xob tsis txaus siab (xws li cov kab mob ua kua lossis cov kab mob ua kua), ua rau tus ntoo khaub thuas uas tsis muaj peev xwm ua kua rau.
Qhov tshwm sim: Tshaj cov microbial txwv, cov khoom lag luam raug kaw, thiab txawm tias muaj teeb meem kev nyab xeeb zaub mov muaj tshwm sim.
Kev daws: Pob valve nrog cov dej ntws tawm tso cai rau nruab nrab kom raug tso tawm tag los ntawm qhov chaw nres nkoj ntws hauv qab.
Corrosion puas
Mob: Residual acid, alkali thiab ntsev cov kua hauv cov tshuaj pipeline yuav crighde valior valfaces thiab shorten valve lub neej.
Kev Kawm Kev Kawm: Ib qho tshuaj pleev cov tshuaj tsis muaj kev tawm dag zog sulfuric acid, ua rau pob valve tsis muaj 3 hlis, ua rau muaj kev xau.
Kev daws: Nws muaj txoj haujlwm ntawm tshem txoj kev corrosive sai sai thiab tiv thaiv valve qauv. Khov thiab nthuav dav
Cov xwm txheej: Nyob hauv Suav teb, thaum cov kav dej sov raug kaw nyob rau lub caij ntuj sov, yog tias tsis muaj dej sov, cov dej seem tuaj yeem khov thiab o, pipes.
Qhov tshwm sim: tawg li qub thiab cov kav dej tawg, ua rau kev siv tus nqi tsawg.
Kev daws: pob li qub nrog dej tso cai rau dej yuav tsum tau nqus dej thaum lub sijhawm poob qis.
ii. Kev Txhim Kho Kev Yooj Yim: Yooj Yim Saib Xyuas thiab Kho Txheej Txheem
Kev Ntsuas Kom Ceev Txo Txo Downtime
Cov hau kev pab cuam: txhuav xov xwm cuam tshuam nrog kev tshem tawm ib lub valve lossis cov kav dej, lub sijhawm {{{}} noj haus ua haujlwm uas feem ntau yuav siv sijhawm ntau teev.
Ntws pob valve: txuas rau txoj kev hose lossis twj tso kua mis tso rau qhov chaw tso dej tso rau hauv cov xov xwm hauv qab 10 feeb, ib qho kev saib xyuas luv luv mus ncig.
Kev tshawb fawb ntaub ntawv: Kev ua beneries nrog cov dej ntws tau tuaj yeem cawm tau ntau dua ib nrab lab daus las ib xyoos nws yuav siv sijhawm kom ntxuav lub oob khab los ntawm plaub teev rau ib qho.
Txhawb tu nyob rau hauv qhov chaw (CIP) thiab kev tsis muaj menyuam hauv qhov chaw (SIP).
Kev ua kom huv: Cov zaub mov thiab tshuaj kev lag luam thiab kev lag luam yeeb tshuaj yuav tsum nres tsheb. Qhov tshwj xeeb txuas ntxiv: qee lub pob li qub nrog cov kav dej ntws uas txuas rau cov roj av uas txuas nrog rau cov dej khov kho thiab ntxuav tawm "
Cov zog: txo tib neeg raug paug rau kev paug thiab ua raws li FDA, GMP thiab lwm yam kev lees paub.
III. Kev Nyab Xeeb Kev Nyab Xeeb: Tswj cov kev pheej hmoo ntawm kev kub siab, qhov kub thiab txias thiab flammable media
Kev ruaj ntseg kev ua haujlwm siab;
Kev pheej hmoo: seem tawm los ntawm high {{0} pa taws lossis roj hauv cov kav dej yuav raug tso tawm sai sai thaum tu lossis tawg.
Kev daws: Pob li qub nrog cov kav dej ntws tawm ntawm cov tso tawm qeeb ntawm lub siab los ntawm kev ua haujlwm kom ntseeg tau.
Cov Qauv Yuav Tsum Tau: Ua raws li cov qauv thoob ntiaj teb xws li API 6D, ISO 17292, thiab muaj Doublicvalval thaiv.
Flammable Media Control
Zauv: Cov roj av uas nyob hauv roj thiab roj pipelines yuav tawg vim vim yog hluav taws xob zoo li qub lossis cov txim taws.
Kev daws: Cov dej ntws yuav tsum tau tsim los ua kom tau raws li cov ntawv pov thawj tawg (xws li ATEX ntawv pov thawj) thiab muaj cov ntawv pov thawj ntawm nitrogen purge chaw nres nkoj kom tshem tawm roj ntau. IV. Kev Taw Qhia Khoom Tsim Qauv Tsim Cov Lus Zoo: Kev Ua Haujlwm Zoo Tshaj Plaws, Kev Sib Koom Tes;
Minimizing khib nyiab
Cov ntsiab lus tshwj xeeb: lub qhov muag yog feem ntau nyob ntawm qhov qis tshaj plaws ntawm lub valve thiab txuas ncaj qha rau txoj kev sib txuas ntws los tiv thaiv kev tshaj xov xwm. Qee cov qauv qauv muaj cov kab pheeb ces kaum txoj kev tsim los kom txo qis me me.
Piv txwv li, lub ven ntawm lub suab nrov tawm hauv lub pob hluav taws xob nrawm nrawm thiab txuas nrog ISO cov qauv rau kev sib dhos sai sai thiab kev tshem tawm, nrog rau kev tu thiab ntxuav tawm.
Cov ntaub ntawv hloov kho tshiab, corrosion - tsis kam, yooj yim los ntxuav
Lub Cev Khoom 316L stainless hlau (zaub mov qib) PVC cov khoom siv qib siab) thiab lwm cov khoom siv corrosion resistant.
Sealants: Food-grade or chemical-grade sealants such as silicone and polytetrafluoroethylene.
Kev kho deg: Electrolytic polishing (roughness tsawg dua los yog sib npaug rau 0.4 μm) kom tau raws li cov kev xav tau.
Ntau hom kev sib xyaw ua ke nthuav cov ntawv thov kev xaiv
Plws + cov qauv: qee cov qauv tso kua dej kuj tseem siv tau raws li kev kuaj chaw nres nkoj rau kev soj ntsuam zoo.
Cov kab dej ntws + vents: nyob rau hauv chav nruab nrog, vents tuaj yeem txuas nrog lub valvecrop valve, paub ntau dua cov `` vents + vents + vents 'vents' '. V. Xaiv cov lus qhia: Yuav ua li cas xaiv txoj kev tso sab nraud
Nruab Nrab Sib Xws
Corrosive Media: 316L PTFE Sealing nplhaib 316L stainless hlau lub cev.
Siab viscosity nruab nrab: xaiv qhov loj ntawm cov hlab ntsha (xws li DN50 lossis loj dua) kom tsis txhob thaiv.
Nruab nrab muaj cov khoom: xaiv ib tus qauv nrog cov av ntws du thiab tsis muaj cov ces kaum tuag los txo cov kev nplua nuj.
Siab thiab kub tau
High-pressure application (>10 MPA): Xaiv cov pob zeb sealing pob Valve. Dej phwj dej yuav tsum tau nruab nrog lub siab - nyem pob khoom.
Ultra -} Cov Ntawv Thov Kub (<-50°C): select cryo-specific ball valve. The drain must be separated by ice.
High temperature applications (>200 degree): Xaiv lub siab - kub {2} {resistant sealing cov khoom (piv txwv li,- puv PTFE).
Kev lees paub thiab cov qauv
Kev lag luam khoom noj khoom haus: FDA, EC1935, triple - - Tus qauv kev noj qab haus huv.
Kws Kev Lag Luam: ASME BPE, GMP, ISO 15848 ntawv pov thawj.
Tshuaj Kev Lag Luam: API 6D, ISO 17292, ATEX TURNION - Cov ntawv pov thawj pov thawj.
Abstract: Digppipe Pob Valve yog kev xaiv Inev Txhim Kho ntawm `` ua haujlwm hloov kho ''.
Hauv cov ntawv thov nrog kev nyiam huv, tshwj xeeb cov xov xwm tshwj xeeb, dej ntws tawm, kev muaj kuab paug thiab kev nyab xeeb ntawm cov khoom lag luam uas ua neeg zoo li qub. Tsis tas li ntawd, los ntawm kev ua kom zoo thiab kev ua haujlwm ntawm lub valve, kev xaiv cov khoom siv rau kev lag luam lossis cov khoom muaj kev nyab xeeb vim kev xaiv tsis zoo.
