Rooj vag Valve vs Riam Valve: Qhov txawv & Siv

Nyob rau hauv industrial pipeline systems, kev xaiv ntawm rooj vag valvethiabriam valvencaj qha cuam tshuam rau kev tswj hwm kev tshaj tawm thiab cov nqi tu. Txawm hais tias lub rooj vag li qub thiab riam rooj vag li qub tshwm sim zoo sib xws hauv kev ua haujlwm, lawv muaj qhov sib txawv hauv cov qauv sab hauv, sealing mechanisms, thiab cov xwm txheej siv tau.

✔️ Rooj vag valvecia siab rau ib qho kev sib txuas lossis ib lub voj voog - zoo li lub rooj vag uas txav mus rau qhov chaw kom ua tiav qhov qhib lossis kaw tag nrho, muab txoj hauv kev du thiab tsis tshua muaj siab poob. Lawv cov rooj zaum hlau tuaj yeem ua tiav ANSI Chav Kawm VI cov pa xau (rau cov mos- rooj zaum), ua rau lawv tsim nyog rau cov kua dej huv xws li roj, nkev, lossis chav. Txawm li cas los xij, thaum lub rooj vag thiab lub rooj zaum nyob rau hauv kev sib cuag nrog cov xov xwm abrasive (xws li, xuab zeb- cov roj crude), lub rooj vag valve sealing kev ua tau zoo degrades vim particle embedment, ua rau sab hauv to.

✔️ Riam rooj vag li qubntiav riam ntse- zoo li lub rooj vag uas muaj peev xwm "slice los ntawm" fibers, pulp, los yog lumpy cov ntaub ntawv nyob rau hauv sludge, thaum elastic rooj zaum (xws li, PTFE los yog roj hmab) muab bidirectional npuas - nruj kaw. Piv txwv li, nyob rau hauv riam rooj vag valve rau slurry daim ntaub ntawv (slurry concentration Ntau tshaj los yog sib npaug rau 40%, particle loj Tsawg tshaj los yog sib npaug zos rau 10mm), lub U-zoo li tus los yog V-zoo li tus chaw nres nkoj tsim enables nws tus kheej- ntxuav ntawm lub sealing ntsej muag, tsis txhob clogging. Standard riam rooj vag li qub feem ntau ua tiav ANSI Class IV to, tab sis hloov cov rooj zaum tuaj yeem ncav cuag Chav V.

Kev sib piv tseem ceeb:

• Sealing mechanism:Rooj vag li qub cia siab rau ntsug; riam rooj vag li qub siv shearing nkaus thiab elastic deformation.
• Muaj feem xyuam media:Lub rooj vag li qub yog siv rau cov dej tsis zoo - abrasive; riam rooj vag li qub ua tau zoo nrog cov khib nyiab, fibers, lossis siab - cov kua dej viscosity (xws li, kev kho dej khib nyiab, ntawv zeb).
• Siab sib txawv thiab kev taw qhia: For high-pressure scenarios (>1500 psi), rooj vag li qub yog nyiam; rau qhov tsis tshua muaj siab (tsawg dua lossis sib npaug li 150 psi) thiab loj - txoj kab uas hla (DN100–DN600) slurry pipelines, riam rooj vag li qub tau pom zoo.

📌 Cov lus nug thiab kev daws teeb meem

Q1: Hauv kev tshaj tawm abrasive, lub valve twg muab kev kaw haujlwm ruaj khov dua?
A: Riam rooj vag li qub muaj qhov zoo dua. Lawv cov ntug txiav tuaj yeem txiav cov khoom, thiab lub rooj zaum elastic tuaj yeem kos cov khib nyiab me me thaum tswj kev sib khi. Nws raug nquahu kom xaiv ib qho kev sib xyaw ntawm cov riam tawv tawv (HRC Ntau dua lossis sib npaug ntawm 55) + lub rooj zaum roj hmab hloov tau, uas tuaj yeem txuas lub neej kev pabcuam los ntawm 3-5 zaug piv rau cov rooj vag qub qub.

Q2: If the pipeline requires frequent cycling (>10 zaug hauv ib teev), qhov twg yog qhov tsim nyog - rooj vag valve lossis riam rooj vag valve?
A: Riam rooj vag valve. Lub rooj vag qhia hauv lub rooj vag valve yog nquag hnav thiab jamming vim kev ua haujlwm nquag; whereas riam rooj vag li qub yog tsim los nrog cov lus qhia thaiv thiab tus kheej -lubricating bushings, thiab qee cov qauv tuaj yeem tiv taus20,000 cycleslossis ntau dua (xws li DeZURIK lossis Orbinox series). Rau siab - zaus pulse tej yam kev mob, riam rooj vag valve nrog apneumatic actuatoryog nyiam.

Cov ntsiab lus xaiv:

📝 Ua raws li cov lus qhia xaiv lub valve rau cov kav xa dej - yog tias qhov nruab nrab yog huv, siab-siab, thiab ua haujlwm tsis tu ncua, xaiv lub rooj vag valve; Yog hais tias qhov nruab nrab muaj impurities, fibers, los yog yuav tsum tau nquag on-off cycles, riam rooj vag valve yog ib tug nqi-zoo thiab txhim khu kev qha tshuaj.COVALVEmuab cov kev hloov kho li qub raws li API 600 thiab MSS SP-81 cov qauv, thiab tuaj yeem muab 3D simulation sealing tsom xam raws li koj cov txheej txheem tsis (kub, viscosity, cov ntsiab lus ntawm cov khoom khib nyiab).
