Stainless hlau rooj vag li qub & Stainless hlau riam rooj vag Valve

Stainless hlau rooj vag li qub vs. Riam rooj vag li qub: Kev sib txawv, xaiv cov ntsiab lus tseem ceeb, thiab kev daws teeb meem

✔️ Hauv kev lag luam piping systems, stainless hlau li qub tau dhau los ua tus qauv kev xaiv hauv cov tshuaj, mining, dej kho, thiab cov ntaub ntawv thiab ntawv kev lag luam vim lawv cov corrosion kuj thiab txhua yam muaj zog. Ntawm lawv,stainless hlau rooj vag valvesthiabstainless hlau riam rooj vag valveqhia cov npe zoo sib xws tab sis muaj qhov sib txawv tseem ceeb hauv cov qauv txheej txheem, kev tshaj xov xwm siv tau, thiab kev saib xyuas yuav tsum tau ua.

I. Core Structure thiab Technical Parameter Comparison

✅Tseem niaj hnub stainless hlau rooj vag li qub siv lub rooj vag qhov rooj lossis lub rooj sib txig sib luag, nrog cov qia txav mus rau qhov chaw kom ua tiav kaw - tawm. 🌈 Lawv qhov chaw sib khi yuav tsum muaj kev sib raug zoo, ua rau lawv haum rau cov kua dej huv lossis cov pa roj. Kev ntsuas siab feem ntau npog Chav Kawm 150 txog Chav Kawm 600.🌈 Rau ib qho DN150 (6-}inch) bore, lub ntsej muag - rau- lub ntsej muag qhov ntev ntawm lub qhov rooj stainless hlau ua raws li ASME B16.10, kwv yees li 292 hli. 🌈 Lub sijhawm qhib thiab kaw yog qhov ntev, thiab nws tsis haum rau cov xov xwm uas muaj cov khoom siv - cov khoom tuaj yeem yooj yim nkag rau hauv qab ntawm lub rooj zaum, ua rau tsis zoo kaw.

✅ Ib qho ntxiv,riam li qub(piv txwv li, riam rooj vag li qub) siv lub qhov rooj ntse -edged. Lub rooj vag ntug yog hardened, feem ntau 6-12 hli tuab, muab ntau dua hardness thiab hnav tsis kam tshaj lub rooj vag zoo tib yam.
✅ Standard6″ riam rooj vag valve(DN150) muaj lub ntsej muag -rau- lub ntsej muag dimension tsim raws li ISO 5752 Series 3, tsuas yog 114 hli (wafer hom) lossis 210 hli (lug hom), uas yog ntau dua 50% luv dua li lub rooj vag valve ntawm tib lub bore.
✅ Cov riam phom ntawm lub qhov rooj riam txiav ncaj nraim rau hauv nruab nrab thaum kaw, shearing fibers, slurry, los yog granular cov ntaub ntawv. Qhov no yog vim li cas nws thiaj li feem ntau hu ua aguillotine valve- ib lo lus tshwj xeeb tshaj yog nyob rau hauv mining thiab kev kho dej khib nyiab, hais txog nws cov guillotine-zoo li txiav txiav.

II. Tej teeb meem thiab kev daws teeb meem engineering

✅ Teeb meem 1:Tom qab rov ua haujlwm hauv kev tshaj xov xwm uas muaj cov khoom sib txuas, lub rooj vag riam lub qhov rooj muaj kev sib khi tsis ua haujlwm - cov khoom ntim rau hauv qab ntawm lub valve lub cev tiv thaiv lub rooj vag los ntawm kev kaw tag nrho.

✅Root Cause Analysis:Coarse hais los yog ntev fibers nyob rau hauv lub slurry nyob rau hauv lub rooj zaum zawj nyob rau hauv qab ntawm lub valve lub cev. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau wafer-hom riam rooj vag li qub, uas nws lub rooj zaum qis tau nthuav tawm hauv qhov dej ntws thiab tsis muaj tus qauv tu tus kheej. Raws li daim ntawv tshaj tawm teb tau tshaj tawm hauvValve ntiaj teb(2021), kwv yees li 33% ntawm riam rooj vag valve tsis ua hauj lwm nyob rau hauv tailings pipelines yog vim stratified tsub zuj zuj ntawm cov khoom nyob rau hauv qab.

📌 Kev daws:
Xaiv lub rooj vag valve tsim nrog ib daim ntawv qhia kev ntxuav tus kheej (scraper). Cov ntawv qhia phaj haum nruj rau ob sab ntawm lub rooj vag, scraping tawm cov khoom siv thaum lub sijhawm qhib txhua qhov mob stroke. Nyob rau tib lub sijhawm, siv cov kab noj hniav uas tsis muaj kab noj hniav hauv qab kom tsis txhob muaj qhov tso tawm.

Teeb meem 2:Yuav ua li cas xaiv txhim khu kev qhariam rooj vag valve lwm tus neegthiab tsis txhob yuav cov khoom tsis zoo uas tsis haum rau kev ua haujlwm?

📌 Kev daws:
Thaum ntsuam xyuas cov neeg muab khoom, thov cov ntaub ntawv hauv qab no plaub yam:

• Kev ntsuas ntsuas siab- Ua raws li API 598. Plhaub ntsuas siab ntawm 1.5 npaug ntawm qhov ntsuas siab (piv txwv li, PN10 valve kuaj rau 15 bar), lub rooj ntsuas siab ntawm 1.1 zaug, nrog lub sijhawm tuav tsis pub tsawg dua 60 vib nas this.
• Cov ntaub ntawv pov thawj traceability (EN 10204 3.1)- Ua pov thawj cov tshuaj muaj pes tsawg leeg (xws li Ni cov ntsiab lus 10–14%, Mo 2–3% rau 316 stainless hlau) thiab cov khoom siv kho tshuab (lub zog tensile Ntau dua lossis sib npaug rau 485 MPa, yield zog ntau dua lossis sib npaug li 170 MPa) ntawm lub cev, rooj vag, thiab qia.
• Lub ntsej muag-to-fab dimension pov thawj- Ntsuas ntev ntawm wafer-hom riam rooj vag valve yuav tsum ua raws li cov chaw tsim khoom thov ISO 5752 tus qauv, nrog kev sib txawv tsawg dua lossis sib npaug li ± 1.5 hli; txwv tsis pub, nws tsis tuaj yeem ua phooj ywg zoo nrog cov kav dej flanges.
• Cov ntaub ntawv tshawb fawb hauv cov ntawv thov zoo sib xws- Tus neeg muag khoom yuav tsum muab tsawg kawg yog ob qhov kev qhia nrog tib qhov nruab nrab (piv txwv li, alumina liab av nkos, dej cawv dub los ntawm papermaking) uas tau ua haujlwm rau ntau tshaj 12 lub hlis, thiab tso cai rau koj hu rau cov kws ua haujlwm hauv teb los txheeb xyuas tus nqi xau thiab qhov sib txawv ntawm lub zog.

III. Khoom siv thiab txheej txheem ntawm cov khoom tseem ceeb - "Valve Riam"

✔️Qhov kev ua tau zoo ntawm cov riam rooj vag valve yog nruab nrab ntawm lub pob valve (piv txwv li, lub rooj vag hniav). Cov txheej txheem kev coj ua yog vuam cov hniav ua los ntawm AISI 420 martensitic stainless hlau mus rau lub rooj vag 316, tom qab ntawd kub kho rau HRC 48-52. Ib tug tsim nyog 6 "riam rooj vag valve yuav tsum tau 500 tag nrho-stroke tsis-load kuaj ua ntej tawm hauv lub Hoobkas, thiab cov hniav yuav tsum tau soj ntsuam los ntawm dye penetrant testing kom tsis txhob muaj kab nrib pleb.

IV. Cov ntsiab lus

📝 Seb seb yuav xaiv lub rooj vag stainless hlau lossis lub rooj vag riam yog nyob ntawm seb qhov nruab nrab puas muaj cov khoom lossis cov fibers. Rau cov dej huv, chav, lossis roj, cov rooj vag qub qub tseem yog cov kev daws teeb meem zoo tshaj plaws. Rau sludge, pulp, ore slurry, thiab cov kev siv zoo sib xws, riam rooj vag li qub - nrog lawv cov qauv luv, kev ntxuav tus kheej riam ntug, thiab kev saib xyuas yooj yim - dhau los ua qhov kev xaiv tsis tau.

📝 Thaum lub sij hawm kev yuav khoom, nruj me ntsis xyuas cov ntaub ntawv kev txawj ntse thiab teb cov ntaub ntawv hais txog ntawm riam rooj vag li qub rau cov neeg muag khoom, thaum tseem ua tib zoo saib xyuas qhov hardness tsis ntawm guillotine valve thiab riam valve, yuav ua kom muaj kev ruaj ntseg ntev ntawm cov kav dej.
