Custom Ductile Iron Sluice Valve: Tsim & Siv

Custom Ductile Iron Sluice Valve: Tsim thiab Daim Ntawv Thov Piav Qhia

✔️ Hauv kev sib txuas ntawm cov dej, cov kav dej, thiab kev tswj xyuas dej, covlub valveyog ib qho ntawm cov khoom siv tseem ceeb tshaj plaws thiab tseem ceeb tshaj plaws. Thaum cov phiaj xwm xav tau lub zog siab dua, kev tiv thaiv corrosion zoo dua, thiab qhov ntev customized, kev cai ductile hlau sluice valve tau dhau los ua qhov kev xaiv sab saum toj rau cov engineers thoob ntiaj teb.

✔️ Kab lus no txheeb xyuas cov txiaj ntsig tseem ceeb ntawm cov li qub no los ntawm plaub qhov loj: cov khoom siv, qhov sib txawv ntawm cov qauv, kev tshawb fawb hauv ntiaj teb, thiab cov txheej txheem xaiv.

1. DI Sluice Valve – Vim li cas thiaj xaiv Cov Hlau Hlau?

✅ Sijhawmnrum hlaumuab tus nqi qis dua, nws tsis muaj kev cuam tshuam thiab ductility.Hlau hlau (DI), los ntawm kev kho spheroidisation, faib graphite nyob rau hauv daim ntawv kheej kheej, txhim kho tensile zog (Ntau tshaj los yog sib npaug rau 420 MPa) thiab elongation (Ntau dua los yog sib npaug rau 10%) thaum khaws zoo castability.

 

✅Rau li qub nrog kev ntsuas siab PN10 ~ PN25 thiab qhov ntau thiab tsawg DN50 ~ DN600, DI cov khoom siv tau zoo tiv thaiv dej rauj thiab hauv av, ua rau nws tshwj xeeb tshaj yog tsim rau cov kav dej faus dej loj (sluice valve water main).

 

✅ Kev tsim kho tsis yog tsuas yog qhov loj thiab cov qauv flange (ANSI / BS / ISO) tab sis kuj nyob rau hauv kev xaiv ntawm cov tsis-nce spindle sluice valve (sab hauv ntsia hlau) los yog nce ntxaiv (sab nraum ntsia hlau) tsim, nrog rau cov add-ons xws li ncua stems, iav neeg teb xov tooj lub thawv, thiab xauv cov cuab yeej.

Rau qhov chaw-tso valve pits, qhov tsis-nce qia tsim txo qhov siab tag nrho thaum qhia valve txoj hauj lwm ntawm qia txiv ntoo tig, tiv thaiv kev ua haujlwm tsis zoo.

 

2. Sluice Valve vs Rooj vag Valve - Lub tswv yim nthuav dav thiab cov qauv sib txawv

✅ Ntau tus neeg siv kev lag luam tsis meej pem cov ntsiab lus "sluice" thiab "gate". Hauv kev xyaum, lawv xa mus rau tib hom valve - ib qho uas siv ntsug disc ( rooj vag) los kaw qhov ntws. Txawm li cas los xij, hauv kev xyaum ua haujlwm, qhov sib txawv ntawm qhov sib txawv ntawm qhov sluice valve vs lub rooj vag valve nyob rau hauv qhov "sluice valve" feem ntau yog hais txog qhov loj-inch, qis-siab li qub siv hauv kev kho dej, kev xa dej tsis zoo, thiab kev siv dej, qhov "qhov rooj valve" npog ntau yam kev lag luam (steam, roj, thiab lwm yam).

 

✅Furthermore, a resilient seated sluice valve (soft‑sealing gate valve) uses an EPDM or NBR rubber‑encapsulated disc to achieve zero leakage (bidirectional sealing), complying with EN 1074 and AWWA C509 standards, while metal‑seated versions are suitable for applications with particulates or elevated temperatures.

 

✅ Lwm qhov kev xaiv tseem ceeb rau kev cai ductile hlau sluice valve yog cov khoom qia - stainless hlau (2Cr13 lossis 304) ua ke nrog tooj liab-alloy txiv ntoo los tiv thaiv corrosion thiab seizing. Lub kaus mom packing siv cov graphite hloov tau los yog PTFE los xyuas kom yooj yim hloov lub caj pas packing txawm tias tom qab kev pab mus ntev.

 

3. Case Study: Agricultural Irrigation System Upgrade in Ho Chi Minh City

Xyoo 2023, cov cheeb tsam ua liaj ua teb ntawm Củ Chi thiab Hóc Môn nyob ib ncig ntawm Ho Chi Minh City, Nyab Laj tau ntsib kev xeb hnyav thiab kev ua haujlwm nyuaj ntawm cov qub cam khwb cia hlau rooj vag li qub, ua rau cov dej siv dej hauv qab 60%. Lub chaw lis dej num hauv zos, hauv kev koom tes nrog lub tuam txhab kev lag luam thoob ntiaj teb, tau xaiv cov kev cai ntawm cov hlau sluice li qub (DN200, PN16, tsis-nce qia + resilient zaum). Cov valve no tau tsim los rau cov kev cai hauv qab no:

• Lub cev:Ductile hlau QT450-10, sab hauv thiab sab nrauv txheej nrog fusion-bonded epoxy hmoov (FBE), thickness Ntau dua los yog sib npaug rau 250μm, los tiv thaiv tropical av corrosion.
• Disc:Tag nrho EPDM-encapsulated, dhau 50,000 lub voj voog kuaj nrog xoom to.
• Kev ua haujlwm:Haum nrog square qia txuas ntxiv thiab cov yuam sij hauv av, ua rau cov neeg ua liaj ua teb ua haujlwm tau yooj yim hauv cov av nkos.

Tom qab qhov project commissioning, lub irrigation system siab poob los ntawm 22%, thiab lub valve tu ncua ncua sij hawm los ntawm peb lub hlis twg mus rau ob lub xyoos, txuag kwv yees li 480 lab VND (ze li USD 20,000) txhua xyoo hauv cov nqi kho. Cov ntaub ntawv no qhia tau hais tias qhov kev hloov pauv ntawm lub rooj vag hlau qhov rooj muaj qhov ua tau zoo dua qub thiab kev sib khi kev ntseeg siab dua li cov khoom siv grey-hlau nyob rau hauv high-humidity, high-load ua liaj ua teb ib puag ncig.

 

4. Cov lus pom zoo xaiv thiab kev yuav khoom

Hauv kev tsim qauv engineering, xyuam xim rau cov ntsiab lus hauv qab no:

• Loj thiab Siab:Raws li tus nqi ntws thiab cov kav dej ua haujlwm siab, refrrau ISO 7259 lossis GB / T 24924 tus qauv.
• Hom qia:Rau lub qhov dej tob tshaj li 2 meters, xav txog qhov tsis nce spindle sluice valve nrog lub gearbox kom txo qis kev khiav hauj lwm torque.
• Sealing Khoom:Lub tshuab dej haus yuav tsum siv EPDM ntawv pov thawj rau WRAS lossis NSF61; Cov dej khib nyiab tuaj yeem siv NBR.
• Kev soj ntsuam xyuas:Plhaub xeem (1.5 × PN), xeem zaum (1.1 × PN), thiab cov ntaub ntawv spectrographic tsom xam (kom ntseeg tau tias nodularity Ntau tshaj los yog sib npaug rau 85%).

Raws li tus kws tshaj lij valve tsum, COVALVEmuaj cov kev pabcuam kev hloov kho tag nrho los ntawm CAD 3D qauv rau finite element tsom xam (FEA), nrog rau tag nrho cov khoom nrog cov ntaub ntawv pov thawj thiab cov ntaub ntawv ntsuas hydrostatic.
