Lub Triple-eccentric Npauj Npaim Valve ua tiav cov qauv hluav taws xob hauv thaj chaw ntawm peb lub ntsej muag
1. Cov Tub Ntxhais thev naus laus zis
| Cov Nta | Kev Siv Ua Haujlwm |
|---|---|
| thawj eccentric | Lub valve cov qia roj axis deviates los ntawm nruab nrab ntawm lub cev valve channel, txo qhov kev sib tiv tauj lub zog ntawm tus npauj npaim phaj thiab lub rooj zaum |
| thib ob Eccentric | Lub chaw ua haujlwm disc hloov kho los ntawm cov sealing nto centre Center, sib sau ua ib qho kev tawm suab tsis muaj kev sib cav sib ceg. |
| thib peb eccentric | Lub khob khob lub kaum sab xis ntawm txoj kev sib nraus nto |
2. Qhov tseem ceeb piv
Xoom so ntswg kev ua tau zoo
Qhov kev sib cuag siab ntawm cov chaw sib khi yog qhov sib cuam tshuam nrog qhov nruab nrab siab. Nws tseem tuaj yeem mus txog Ansi Vir VI Dowage txheem hauv PN160 (Cl900) Kev ua haujlwm tsis zoo, thiab cov hlau hluav taws xob ua haujlwm to<0.001%.
Ultra-Tsawg Txhuam Txhuam Kev Plawv
Qhov ua kom zoo ntawm tus npauj npaim suab traijory txo cov kev sib txhuam sib ze ntawm {% piv nrog ob chav eccentric valve. Lub zog ntawm DN600 valve hluav taws xob actuator tuaj yeem txo rau 1.5kw qib.
Kev yoog raws li kev ua haujlwm hnyav
Qhov Kub Kub Ntau: {{-196 degree (ua kua nitrogen) rau {{1} degree (he degree (he degree flue roj)
Media Compatibility: Cov kua muaj cov khoom seem (particle loj dua lossis sib npaug ntawm 3,}}}), thiab siab viscosity (tsawg dua lossis sib npaug zos
Lub sij hawm ntev kev saib xyuas-dawb
Tus nqi ntawm tus khub nyuaj foob yog<0.005mm/year, and the service life under typical working conditions can reach 15-20 years (opening and closing >500, 000} sijhawm).
3. Raug ntawv thov cov xwm txheej
| Muaj Daim Teb | Qhov tseem ceeb Daim Ntawv Thov Cov Ntsiab Lus | Qhov taw qhia kev ua haujlwm |
|---|---|---|
| Petrochemical Kev Lag Luam | Reventeration Nplaim Roj Roj Kev Cai ntawm Catalytic Crushing Ua Tsev (Qhov Kub Kuj 600 Degree + Particle Yaig Vision) | Sealing nto hardness ntau dua los yog sib npaug ntawm HRC60 |
| Nuclear Fais Fab | Lub tsev loj rho tawm valve (hluav taws xob tsis kam + xoom sokage) | ASME NQA -1 Daim Ntawv Pov Thawj |
| LNG Cia Thiab Tsheb Thauj Mus Los | -162 degree ultra-tsawg kub roj ultra-tsawg kub liquefied nkawv ntuj pipeline txiavoff | Cov khoom siv tsawg kub cuam tshuam kev nruj me ntsis ntau dua los yog sib npaug rau 100j @ -196 degree |
| Metallurgical Kev Lag Luam | Moj tej tawg ua kom sov rauv roj residual high zog zog tiam (TRT) system tswj | Withstand kev kub siab ± 1Mpa \/ thib ob |
4. Cov ntsiab lus tseem ceeb rau kev xaiv thiab siv
Txhim kho ntawm kev teeb tsa kev teeb tsa
Kev kub siab ua haujlwm: Inconel 625 valig zaum + Stellite 6 nyuaj alloy txheej yog nyiam
Corrosive Media: Hastelloy C276 Valve Lub Cev + PTFE qhwv Valve Qia
Tsav Tsheb Sib Tw
Txoj kab uas loj loj tshaj plaws (dn ntau dua los yog sib npaug rau 800) yuav tsum tau cov actuator hydraulic nrog cua ntau dua lossis sib npaug rau 200kn
Thaum pneumatic acuatators tau raug xaiv hauv qhov tawg-pov thawj thaj chaw, ATEX \/ IECEX ntawv pov thawj yuav tsum tau ua tiav
Teeb tsa thiab tshuaj xyuas cov lus qhia tshwj xeeb
Flange parallelialism sib txawv tsawg dua los yog sib npaug rau 0. 1mm \/ 100mm kom tsis txhob raug foob los ntawm eccentric load
Ntau tshaj 3, {000 cua thuv mis ({{}}} degree ↔650 degree) yuav tsum ua ntej tawm hauv lub hoobkas
Lub valve hom no siv Torque sealte sealing mechanism coj los ntawm cov qauv npauj npaim ntawm cov kev ua haujlwm hauv kev ua haujlwm xws li kub, thiab kev mob siab. Nws cov tseem ceeb tus nqi nyob rau hauv txo cov nqi zog tag nrho ntawm ntau dua 40%, thiab nws yog cov khoom siv tseem ceeb rau kev txhim kho cov txheej txheem ntawm cov txheej txheem.
