Dab tsi yog riam rooj vag valves
Riam rooj vag valve (KGVs)- tseem hu ua qhov rooj vag swb lossis riam valves - yog cov khoom siv tswj kev ntws tshwj xeeb uas tau tsim los tswj cov khoom siv viscous, abrasive, thiab fibrous hauv cov chaw ua haujlwm hnyav. Phau ntawv qhia no tshuaj xyuas lawv cov qauv tsim, cov ntsiab cai ua haujlwm, thiab cov ntawv thov tshwj xeeb rau cov lag luam.
Tsim Qauv Tseem Ceeb & Kev Ua Haujlwm Mechanism
Lub qhov rooj vag riam siv lub qhov rooj ntse, zoo li hniav kom txiav cov slurries thiab cov khoom khov. Cov khoom tseem ceeb suav nrog:
√ Rooj Vag Hniav:Phaj zoo li wedge (lub kaum sab xis 5°) txiab cov khib nyiab.
√Lub kaw lus kaw:Cov rooj zaum hlau/elastomer ua kom tsis muaj qhov xau.
√Cov Kev Xaiv Tsav Tsheb:Kev ua haujlwm ntawm tes, pneumatic, hluav taws xob, lossis hydraulic.
Kev Ua Haujlwm:
→ Xaus:Cov hniav hniav nqis los, txiav los ntawm cov xov xwm thiab nias rau ntawm lub rooj zaum rau lub foob npuas-nruj.
→Qhib:Kev rub rov qab sai sai ua rau txoj kev ntws tawm tam sim ntawd, txo qhov tsis ua haujlwm.
Cov txiaj ntsig tseem ceeb ntawm kev ua tau zoo
→Kev Tiv Thaiv Kev Sib Txhuam:Cov ntaub ntawv tawv (piv txwv li, cov rooj zaum polyurethane) tiv taus kev yaig ntawm cov khoom me me.
→Tsim Qauv Me:Kev tsim kho uas sib dua thiab tsis hnyav ua rau txuag tau qhov chaw hauv cov nroj tsuag uas muaj neeg coob coob.
→Xoom To:Siv tshuab dual-seal rau cov kua dej siab/viscous.
→Kev Txij Nkawm Tsawg:Cov qauv yooj yim txo qhov zaus kho.
→Kev ntws ob txoj kev:Ruaj ntseg cov kav dej tiv thaiv kev rov qab los.
Kev Nkag Siab Txog Kev Lag Luam: Cov KGVs uas muaj polyurethane zaum ntev dua 300% hauv cov kab slurry abrasive piv rau cov roj hmab foob.
Cov Ntawv Thov Kev Lag Luam
Cov qhov rooj vag riam zoo dua qhov uas cov qhov rooj ib txwm ua tsis tau zoo:
Kev khawb av& Cov Khoom Noj Khoom Haus:
Kev thauj cov slurry, kev tswj cov tailings, kev tswj cov thee slurry.
Kev daws teeb meem uas nyiam tshaj plaws:Cov KGVs uas muaj polyurethane tiv taus kev yaig ntawm silica / xuab zeb.
Kev Kho Dej Pov Tseg:
Tswj cov dej phwj tuaj nrog cov fibers, grit, thiab cov khoom khov.
Kev Tsim Hluav Taws Xob:
Kev tswj cov hmoov tshauv ya hauv cov nroj tsuag uas siv hluav taws xob.
Cov Ntawv thiab Cov Ntawv:
Kev tswj hwm cov kua nplaum uas muaj zog heev.
Roj thiab Roj Av:
Kev hloov roj crude nrog xuab zeb / sediment.
Vim Li Cas Thiaj Qhia Txog Riam Gate Valves
Kev Tiv Thaiv Khib Nyhiab: Kev tsim cov hniav tiv thaiv kev txhaws los ntawm cov ntaub, cov ntoo me me, lossis cov pob zeb.
Cov Kev Xaiv Huv Si: Cov ntaub ntawv ua raws li FDA rau cov khoom noj / tshuaj (piv txwv li, kev ua cov mis nyuj).
Kev Siv Nyiaj Txiag Zoo: 30% qis dua tus nqi siv tas mus li piv rau lub pob li qub hauv kev pabcuam slurry.
Cov Lus Qhia Txog Kev Xaiv
Cov Khoom Siv Abrasive: Xaiv cov rooj zaum polyurethane (Shore A 95+ hardness).
Cov Kua Uas Muaj Kev Kub Ntxhov: Qhia kom meej tias yog 316SS lossis duplex steel lub cev.
Lub Luag Haujlwm Siab: Cov actuators tsis siv neeg rau >100 lub voj voog / hnub.
