Los ntawm Kev Tsim Kho Rau Kev Xaiv: Saib Ntawm Cov Txheej Txheem Txheej Txheem Tseem Ceeb Ntawm Cov Pob Valve

Hauv cov khoom noj, tshuaj, bioengineering thiab lwm yam kev lag luam uas xav tau kev huv huv, huv pob li qub yog qhov tseem ceeb ntawm kev tswj cov kua dej, thiab nws qhov tseeb tsim thiab kev xaiv muaj txiaj ntsig ncaj qha cuam tshuam rau kev ruaj ntseg thiab cov khoom zoo. Hauv daim ntawv no, cov qauv tsim, cov ntsiab lus tseem ceeb thiab kev xaiv cov logic yog siv los txheeb xyuas cov ntsiab lus ntawm kev huv pob valve.
I. Design Principple: structural innovation centered on cleanness.
Tus qauv tsim ntawm lub pob huv huv yog kom paub txog peb lub hom phiaj ntawm 'xoo muaj kuab lom, ntxuav yooj yim thiab ua haujlwm ntev" los ntawm kev ua kom zoo dua cov khoom siv, cov dej ntws thiab cov qauv sib khi.
1.Material Systems: Sib npaug ntawm corrosion kuj thiab Biocompatibility
Cov khoom tseem ceeb: 316L stainless hlau nrog rau molybdenum yog nyiam. Nws yog peb zaug ntau cov tshuaj chlorine- tiv taus ntau dua li 304 stainless hlau thiab tsim nyog rau kev ua haujlwm hauv ntsev thiab kua qaub. Piv txwv li, ib lub tuam txhab mis nyuj mis ua yuam kev siv 304 stainless hlau li qub hauv nws cov tshuaj chlorine -muaj CIP tu system. Rau lub hlis tom qab, tag nrho cov kab ntau lawm tau raug kaw vim muaj cov poholes thiab perforations.
Sealing khoom: raws li tus yam ntxwv ntawm nruab nrab xaiv.
PTFE (polytetrafluoroethylene (PTFE)): Kub-50℃rau 200 degree, tau tshaj acidic thiab alkaline xov xwm, zoo tshuaj stability.
Silicone roj hmab: Resistant mus rau qhov kub ntawm -60℃mus rau 230℃rau kev thauj mus los ntawm sterile tshuaj daws nyob rau hauv high-purity media xws li tshuaj tiv thaiv.
EPDM roj hmab: Resistant mus rau qhov kub ntawm -40℃thiab 150 degree, haum rau chav ua kom tsis muaj menyuam, xws li pasteurization hauv kev ua zaub mov.
2. kwj tsim: Qhov kawg Quest rau Deadless Lub kaum sab xis thiab qis Residue
Tag nrho cov qauv caliber: txoj kab uas hla ntawm tus kheej yog zoo ib yam nrog lub puab txoj kab uas hla ntawm lub raj, txo qhov nruab nrab deposition. Piv txwv li, cov yeeb nkab tseem ceeb rau cov kua txiv hmab txiv ntoo hauv lub tshuab ua kua txiv hmab txiv ntoo siv aa DN125 puv - pob valve, uas txo cov dej tsis kam los ntawm 40% piv rau li qub, yog li tsis txhob muaj kev pheej hmoo ntawm kev lwj los ntawm cov kua txiv hmab txiv ntoo ntxiv.
Kev kho deg: 0.5μM (Ra Tsawg dua lossis sib npaug ntawm 0.8 μM) electron polishing tau siv rau sab hauv phab ntsa rau daim iav nyhuv. Tom qab daim ntawv thov ntawm cov txheej txheem no nyob rau hauv lub aseptic kua tshuaj xa pipeline ntawm ib tug kws Hoobkas, tus pass tus nqi ntawm microbial nrhiav kom tau nce los ntawm 92% mus rau 99.9%.
Kev tswj lub kaum sab xis: weld hloov chaw R lub kaum sab xis Ntau dua lossis sib npaug li 3 hli, kab noj hniav qhov tob Tsawg dua lossis sib npaug li 1.5 npaug ntawm txoj kab uas hla. Los ntawm kev ua kom zoo dua qhov tuag-lub kaum sab xis tsim, tag nrho cov yeeb nkab tu lub sij hawm ntawm lub brewery lim pipeline raug txo los ntawm 2 teev mus rau 40 feeb.
3. Sealing qauv: Dual lav ntawm xoom to thiab puas kuj
PTFE npog tag nrho: Tag nrho cov phaj npog yog tsim los tiv thaiv kev sib cuag nrog hlau. Tus kab mob sib kis tau txo qis qis dua 0.01% tom qab cov qauv tau txais kev pom zoo hauv cov kav dej nruab nrab ntawm lub chaw kuaj kab mob lom.
Muab ob npaug rau Stud Filling: Muab lub siab disc caij nplooj ntoos hlav rau kev sib khi zoo. Tom qab ib nrab lab qhib thiab kaw cov kev xeem, cov dej tseem ceeb regulator valve leakage ntawm cov dej phwj tuaj kho cov nroj tsuag tseem ua tau raws li theem ntawm rau (tsawg dua los yog sib npaug rau 0.01% rated flow).
ii. Core Parameters: Quantitative indicators, As txhais cov kev ua tau zoo ciam teb
Kev ua tau zoo ntawm lub pob valve yuav tsum tau ntsuas ntau los ntawm cov ntsiab lus hauv qab no:
Nominal inch (DN) thiab Rated Pressure (PN)
Txoj kab uas hla: DN15 txog DN200, feem ntau DN20 txog DN100. Piv txwv li:
Haus Dej Cog Filling Supervisor: DN 50 rau cov kev cai loj filling;
Pharmaceutical Hoobkas aseptic kua xa: DN25, ua tau raws li kev tswj xyuas qhov tseeb.
Kev ntsuas siab: PN1.6 txog 4.0 MPA. Rau cov xwm txheej siab (xws li autoclaving), PN4.0MPa yuav tsum raug xaiv. Lub qhov hluav taws xob tseem ceeb ntawm lub tank cia cov mis nyuj nyoos yog nruab nrog PN1.6MPa valve, uas ua rau muaj kev ruaj ntseg foob txawm tias muaj kua ntau.
2. Kub adaptability
Ua haujlwm kub: -40℃txog 200℃(nyob ntawm cov khoom sib khi). Piv txwv li:
Silicone roj hmab foob: -60℃rau 230 degree, haum rau ultra-tsawg kub xov xwm;
PTFE foob: haum rau -50℃rau 200 degree, rau feem ntau huv si ua hauj lwm tej yam kev mob.

Xaus:
Kev xaiv ntawm lub pob valve yog ib qho kev sib tham raws nraim ntawm qhov yuav tsum tau ua -tsis muaj- cov kev daws teeb meem. Los ntawm kev xaiv cov khoom siv rau kev tsim cov raj xa dej, los ntawm cov qauv ntawv pov thawj mus rau txoj kev tsav tsheb, txhua qhov kev ntsuas yuav tsum ua kom haum rau qhov tob ntawm cov txheej txheem. Los ntawm kev txheeb xyuas cov ntsiab lus tseem ceeb thiab ua raws li kev xav ntawm kev xaiv, cov tuam txhab tsis tuaj yeem tsuas yog zam kev pheej hmoo xws li "kev tsis sib haum ntawm cov ntaub ntawv" thiab "kev suav tsis raug ntawm Cv qhov tseem ceeb"', tab sis kuj tseem txhim kho kev tsim khoom thiab cov khoom zoo los ntawm tus nqi- cov kev daws teeb meem zoo. Niaj hnub no, kev tsim khoom huv huv tau dhau los ua tus qauv kev lag luam, qhov tob ntawm kev huv huv pob li qub txiav txim siab qhov siab ntawm kev lag luam.
