Dab tsi ntawm Sanitary Check Valves Muaj?

Sanitary check li qub yog ib -txoj kev li qub uas tsim tshwj xeeb rau cov khoom noj, tshuaj thiab kev lag luam lom neeg. Nws lub luag haujlwm tseem ceeb yog los tiv thaiv kev thim rov qab thiab kev ua qias tuaj los ntawm kev qhib thiab kaw lub disc lossis diaphragm kom paub txog qhov unidirectional ntws ntawm kev tshaj tawm. Nyob ntawm cov qauv, kev sib txuas hom thiab cov yam ntxwv ntawm cov khoom, nws tuaj yeem muab faib ua ntau hom hauv qab no:
I. Kev faib tawm los ntawm hom qauv
Lift Check Valve
Nta: Disc plam raws qhov chaw ntsug ntawm lub cev valve, sealing npog ntawm lub rooj zaum valve. Thaum cov dej ntws mus rau pem hauv ntej, lub disc yog lifted; thaum cov kua txav mus rau qhov sib txawv, lub disc poob rov qab los txiav tawm qhov nruab nrab.
Lub zog: kev ua tau zoo sealing zoo, haum rau me me ntws, siab sealing yuav tsum (xws li kev faib tshuaj, khoom noj khoom haus, thiab lwm yam).
Kev txwv: Cov kua dej yog nqaim, lub siab poob siab yog qhov loj thiab yuav tsum muaj kab rov tav installation.
Khoom siv: Valve lub cev feem ntau yog 304 stainless hlau (lub hom phiaj dav dav) lossis 316L stainless hlau (siab corrosivity / siab huv). Disc muaj nyob rau hauv 316L stainless hlau, zaub mov- qib silicone roj hmab lossis PTFE.
Swinging Check Valve
Nta: Disc yog disc -zoo li tus thiab tig ib ncig ntawm lub qhov rooj ntawm lub rooj zaum channel. Lub valve qhib thaum cov kua dej ntws mus rau pem hauv ntej thiab kaw thaum cov kua ntws tawm ntawm qhov sib txawv.
Lub zog: Streamlined flow channel, tsis tshua muaj kev tiv thaiv, haum rau loj, tsis tshua muaj txaus tus nqi los yog pulsating txaus scenarios (xws li, kho dej loj, concentrated kua txiv, thiab lwm yam).
Kev txwv: Kev ua haujlwm foob yog me ntsis qis dua li nqa hom foob. pulsating ntws yuav tsum zam.
Khoom siv: Lub cev yog tib yam li lub elevator thiab lub disc tuaj yeem ua los ntawm 316L stainless hlau lossis PTFE.
Diaphragm Check Valve
Nta: qhib thiab kaw los ntawm deformation ntawm elastic diaphragm (xws li silicone roj hmab), tsis muaj kev sib cuag, muaj zog los tiv thaiv - kev ua qias tuaj.
Lub zog: Haum rau kev ua kom huv thiab corrosive media (xws li kab lis kev cai nruab nrab ntawm tes, kua qaub), txhawb kev tu ntau zaus.
Txwv: Tus nqi ntws yog qhov kawg; feem ntau yog siv rau me me mus rau nruab nrab diameters.
Khoom siv: Valve lub cev feem ntau yog 316L stainless hlau, diaphragm rau zaub mov qib silicone roj hmab lossis PTFE.
ii. Los ntawm Txoj Kev Sib Txuas
Ceev-Mount (Clamp Txuas)
Nta: ISO tus qauv clamp tsim, kev them nyiaj yug ceev disassembly, yooj yim los ntxuav thiab tswj.
Lub hom phiaj: Tsawg ntws, nruab nrab ntws, siab zaus yuav tsum tau tu (xws li cov khoom noj siv mis, kab haus lub raj mis).
Specification: Nominal txoj kab uas hla DN15-DN100, chav kawm siab PN 1.6-3.0 MPA.
Hom Flanged
Nta: huv flanges ntawm ob kawg ntawm lub cev valve, txuas nrog cov yeeb nkab los ntawm bolts, muaj zog sealing.
Lub hom phiaj: Txoj kab uas hla loj, kev kub siab, cov kav dej loj uas yuav tsum tau muaj kev txhim kho ruaj khov (xws li, cov chaw xa tshuaj, cov kav dej huv).
Specification: Nominal txoj kab uas hla DN50-DN150, siab ntsuas PN1.6-3.0 MPA.
Welded Hom
Nta: Lub cev valve yog tsau ntawm ob qho kawg ntawm cov yeeb nkab los ntawm vuam (lub taub qab vuam / lub qhov (socket) vuam), tsis muaj qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob, thiab siab ntev - lub sijhawm ruaj khov.
Kev siv: ntev- lub sij hawm ruaj ruaj, siab sealing yuav tsum, tsis tas yuav tshem tawm ntau zaus (xws li cov kav dej tsis muaj menyuam, siab - siab huv dej mains).
Specification: DN50 thiab saum toj no rau pob tw vuam thiab DN50 thiab hauv qab no rau lub qhov (socket) vuam.
III. Los ntawm Cov Khoom Siv thiab Ntawv Pov Thawj
304 Stainless hlau Valve lub cev
Daim Ntawv Thov: Cov txheej txheem ua zaub mov niaj hnub (piv txwv li, lub raj mis dej haus, cov khoom noj khoom haus tso rau hauv lub tank).
Kev lees paub: ua tau raws li FDA cov qauv kev noj qab haus huv.
316L Stainless hlau Valve lub cev
Lub Hom Phiaj: Ib puag ncig zoo corrosive lossis huv huv (piv txwv li, kev xa tshuaj acidic, kev xa khoom ntawm cov kab lis kev cai ntawm tes).
Daim ntawv pov thawj: Ua raws li 3A cov qauv ntawv pov thawj, qee cov qauv tau txais EC1935 daim ntawv pov thawj qib zaub mov.
Khoom tshwj xeeb Valve Disc / Diaphragm
Silicone Roj Hmab: Flexible foob, kub resistant (saum txwv rau 200 degree), haum rau aseptic scenarios.
Polytetrafluoroethylene (PTFE): Kub thiab corrosion resistant (sab sauv txwv 260 degree), haum rau heev corrosive media.
IV. INTRODUCTION Daim ntawv thov Scenarios thiab xaiv cov lus pom zoo
Pharmaceutical: lub ntsiab 316L valve lub cev + silicone roj hmab diaphragm (3A daim ntawv pov thawj) thiab lwm yam tshuaj xa cov kav dej.
Kev ua zaub mov: yeem 304/316L valve lub cev + stainless hlau valve (FDA ntawv pov thawj), feem ntau yog rau cov kua txiv hmab txiv ntoo, thiab lwm yam.
Loj -tej dej kho dej: Kev siv viav vias flanges lossis kev sib txuas welded, xws li cov kav dej huv hauv cov chaw kho dej, raug pom zoo.
High-ntau zaus tu scene: Kev sib txuas ceev yog yooj yim dua, xws li cov kab feeder hauv cov kab ntau lawm.
Muaj zog corrosive nruab nrab: 316L valve lub cev + PTFE valve disc rau acidic tshuaj xa pipelines, thiab lwm yam.
