Dab tsi yog Kev Siv Cov Diaphragm Valves?

Kev siv cov diaphragm li qub
Diaphragm valve (tseem hu ua daim ntawv valve) yog lub valve uas siv cov diaphragm hloov pauv (daim ntawv) ua qhov qhib thiab kaw lub ntsiab kom txiav tawm cov xov xwm ntws. Nws cov yam ntxwv loj tshaj plaws yog qhov nruab nrab yog sib cais los ntawm diaphragm thiab tsis tuaj yeem sib cuag nrog txhua qhov txav ntawm lub cev valve. Yog li ntawd, nws yog thawj qhov kev xaiv valve uas tsis tuaj yeem hloov tau raws li ntau yam haujlwm tshwj xeeb.
I. Core Applications (vim li cas?)
1.Conveying Corrosive Media
Qhov no yog qhov tseem ceeb tshaj plaws thiab classic daim ntawv thov ntawm diaphragm valve. Txij li thaum lub diaphragm tag cais cov kua corrosive (xws li muaj zog acid, muaj zog alkalis, aqua regia, hydrofluoric acid, concentrated sulfuric acid, sodium hypochlorite, thiab lwm yam) los ntawm cov hlau ib feem ntawm lub valve valve lub cev, lub cev tsis corroded; tsuas yog lub diaphragm thiab lub rooj zaum tuaj rau hauv kev sib cuag nrog nruab nrab. Yog li, diaphragm valve yog yuav luag tus qauv teeb tsa ntawm cov kua qaub thiab alkali pipelines hauv kev lag luam tshuaj.
2.Kev thauj mus los ntawm cov xov xwm uas muaj cov khoom, Fibers thiab High Viscosity
Txoj kev khiav ntawm lub diaphragm valve yog ncaj nraim tsis muaj lub kaum sab xis tuag. Thaum lub diaphragm kaw, nws tuaj yeem ua tiav thiab kaw cov khoom thiab cov fibers, tsis yog cov khoom tau daig zoo li pob li qub thiab lub rooj vag li qub. Yog li ntawd, tshwj xeeb tshaj yog tsim rau kev thauj cov sludge, av nkos, pulp, fiber ntau ncua kev kawm ntawv, khoom noj khoom haus jam, chocolate phoov thiab lwm yam "qhuav" xov xwm.
3. Sanitary Control nyob rau hauv cov zaub mov, tshuaj thiab tshuaj lom neeg kev lag luam
Qhov no yog lwm qhov tseem ceeb daim ntawv thov scenario rau diaphragm li qub. Txij li thaum lub diaphragm valve tsis muaj lub thawv ntim khoom (tsis zoo li lub rooj vag li qub, tsis muaj qhov teeb meem ntawm cov khoom xau), qhov nruab nrab tau ntim tag nrho los ntawm lub diaphragm valve kom tiv thaiv kom tsis txhob muaj kuab paug thiab nkag mus rau sab nraud. Yog li ntawd, diaphragm li qub (tshwj xeeb tshaj yog huv diaphragm li qub) yog ib qho ntawm feem ntau siv li qub nyob rau hauv kev lag luam uas muaj siab huv yuav tsum tau xws li tshuaj, zaub mov thiab dej haus, khoom noj siv mis, brewing, thiab kev kho dej ntshiab.
4. Kev xa cov tshuaj lom neeg ntau, nplaim taws, tawg thiab muaj txiaj ntsig tshaj tawm
Txij li lub diaphragm valve yog tib hom valve uas muaj peev xwm ua tiav xoom xau (diaphragm yog kaw tag nrho tsis muaj cov ntsiab lus to ntawm lub qia), nws yog qhov kev xaiv nyab xeeb tshaj plaws rau kev xa cov pa roj carbon monoxide (xws li chlorine thiab phosgene), flammable thiab explosive media (xws li hydrogen thiab natural gas), thiab cov xov xwm muaj txiaj ntsig (xws li cov khoom siv ultrapure 6).
ii. Piv txwv ntawm kev thov kev lag luam tshwj xeeb
Kev lag luam tshuaj lom neeg: tswj kev pub noj thiab tso tawm los ntawm cov kua qaub- lub hauv paus tso tsheb hlau luam, reactor hauv qab tso tawm, cov dej khib nyiab, thiab lwm yam.. Diaphragm li qub yog thawj qhov kev xaiv rau yuav luag txhua daim ntawv thov uas muaj corrosive heev.
Kev lag luam kev kho dej: cov chaw kho dej khib nyiab Sludge thauj, cov tshuab xa tshuaj (PAC, PAM, acid-cov khoom siv hauv qab, thiab lwm yam) cov tshuaj siv tshuaj, dej ntshiab, dej deionized tswj kav.
Kev lag luam tshuaj: pub thiab tso tawm hauv fermentation tso tsheb hlau luam, CIP (hauv qhov chaw tu), nruab nrab tswj hauv cov kav dej aseptic. Sanitary diaphragm li qub yog cov khoom siv hauv GMP kev cob qhia.
Kev lag luam zaub mov thiab dej haus: tswj kev thauj mus los ntawm jams, syrups thiab chocolate syrup; pub thiab tawm hauv npias fermentation tanks; kaw cov kua mis thiab kua txiv kab.
Semiconductor thiab electronics industries: Ultrapure dej (UPW) pipelines, siab -purity tshuaj thauj thiab tshwj xeeb gas pipeline tswj; daim ntawv thov yuav tsum tau muaj kev xau siab heev.
Daim ntawv kev lag luam: Diaphragm li qub yog qhov ruaj khov dua li lwm cov li qub vim lawv cov khoom siv fiber ntau thiab abrasive thiab siv los thauj thiab tswj cov dej ntws ntawm cov ntaub so ntswg thiab cov khoom tshem tawm.
Metallurgy: Diaphragm li qub yog tsim rau kev xa cov ore slurry, tswj tailings slurry thiab ntxiv flotation reagents. Cov xov xwm no yog corrosive thiab muaj cov khoom loj.
Kev lag luam fais fab: Diaphragm li qub feem ntau yog siv rau kev sib ntxiv ntawm cov tshuaj nyob rau hauv tshuaj kho dej hauv cov nroj tsuag fais fab (ammonia ntxiv, hydrazine ntxiv, kua qaub- puag ncig, thiab lwm yam).
III. Kev txwv ntawm Diaphragm Valves: Thaum tham txog cov ntawv thov, lawv cov kev txwv yuav tsum tau hais kom meej:
Tsis haum rau qhov kub thiab txias siab. Cov ntaub ntawv diaphragm (rubber, PTFE, thiab lwm yam) muaj kev txwv thermal tsis kam. Feem ntau, mos sealing diaphragm li qub yog tsim rau siv ntawm qhov kub ntawm -20℃thiab 150 degree. Tsis tas li ntawd, lub diaphragm muaj hnub nyoog thiab deforms. Tsis tas li ntawd, cov diaphragm li qub feem ntau tsis muaj qhov ua haujlwm siab thiab feem ntau nyob ze ntawm PN10 txog PN16, ua rau lawv tsis haum rau kev siv nyob rau hauv cov xwm txheej siab.
Tsis haum rau cov kav dej loj loj. Diaphragm li qub feem ntau yog nruab nrab ntawm DN50 thiab DN300 nyob rau hauv txoj kab uas hla. Loj dua txoj kab uas hla, tus nqi siab dua thiab kev ua haujlwm tsis zoo.
Lawv tsis haum rau kev tshaj tawm uas muaj cov tawv tawv, cov khoom loj. Thaum lub diaphragm li qub tuaj yeem tuav cov fiber ntau thiab av nkos, qhov loj, ntse, tawv hauv nruab nrab (xws li shards iav los yog chunks ntawm ore) tuaj yeem tsoo lub diaphragm valve.
IV. Kev Taw Qhia Hauv luv luv, lub hom phiaj tseem ceeb ntawm cov diaphragm li qub tuaj yeem suav nrog hauv ib kab lus: nyob rau hauv plaub yam kev tiv thaiv corrosion, cov khoom me me, kev nyiam huv siab thiab tsis muaj qhov to, diaphragm li qub yog qhov kev xaiv zoo tshaj plaws, irreplaceable rau lwm yam li qub.
Nov yog qhov koj tuaj yeem nco qab:
Rau corrosive media → siv diaphragm li qub
Yog tias qhov nruab nrab (muaj cov khoom, fibers lossis av nkos) tsis huv, → siv cov diaphragm li qub
Zero to yuav tsum tau (khoom noj khoom haus, tshuaj) → siv diaphragm li qub
Toxic, flammable lossis muaj txiaj ntsig tshaj tawm → siv cov diaphragm li qub
