Lub luag haujlwm tseem ceeb & Kev Xaiv Cov Ntsiab Cai ntawm Valves

Valves yog ib qho tseem ceeb ntawm cov kav dej hauv kev lag luam thiab ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tsim khoom.

Ⅰ. Lub luag haujlwm tseem ceeb ntawm lub valve

1.1 Hloov thiab txiav tawm xov xwm:rooj vag valve, npauj npaim valve, pob valve tuaj yeem xaiv tau;

1.2 Tiv thaiv qhov backflow ntawm nruab nrab:kos valvetuaj yeem xaiv tau;

1.3 Kho lub siab thiab ntws tus nqi ntawm qhov nruab nrab: yeem kaw-off valve thiab tswj valve;

1.4 Kev sib cais, sib xyaw lossis faib tawm: ntsaws valve,rooj vag valve, tswj valve tuaj yeem xaiv;

1.5 Tiv thaiv kom tsis txhob muaj qhov nruab nrab ntawm qhov siab tshaj qhov ntsuas tus nqi txhawm rau ua kom muaj kev nyab xeeb ntawm cov kav dej lossis cov khoom siv: kev nyab xeeb valve tuaj yeem xaiv.

Kev xaiv ntawm li qub feem ntau yog los ntawm kev xav ntawm kev ua haujlwm tsis muaj teeb meem thiab kev lag luam.

Ⅱ. Kev ua haujlwm ntawm lub valve

Muaj ntau ntau yam tseem ceeb koom nrog, thiab ntawm no yog cov ncauj lus kom ntxaws txog lawv:

2.1 Qhov xwm ntawm cov kua conveying

Hom kua: Txawm tias cov kua dej yog kua, roj, lossis vapor ncaj qha cuam tshuam rau kev xaiv ntawm lub valve. Piv txwv li, cov kua yuav xav tau lub valve kaw, thaum cov pa roj tuaj yeem tsim nyog rau cov pob li qub. Corrosiveness: Corrosive kua yuav tsum tau corrosion-resistant cov ntaub ntawv xws li stainless hlau los yog tshwj xeeb alloys. Viscosity: Cov kua viscosity siab yuav xav tau cov kab uas loj dua los yog tsim tshwj xeeb li qub kom txo tau qhov txhaws. Cov ntsiab lus Particle: Cov kua dej uas muaj cov khoom siv yuav xav tau cov ntaub ntawv hnav-tiv taus lossis tsim tshwj xeeb li qub, xws li pinch li qub.

2.2 Kev ua haujlwm ntawm lub valve

Hloov tswj: Rau qee lub sijhawm uas tsuas yog qhov kev hloov pauv yuav tsum tau ua, pob li qub lossisrooj vag li qubyog tej kev xaiv.

Flow Regulation: Thaum yuav tsum muaj kev tswj xyuas kom meej, lub ntiaj teb li qub lossis tswj li qub yog qhov tsim nyog.

Kev Tiv Thaiv Backflow:Kuaj li qubyog siv los tiv thaiv cov kua dej rov qab.

Shunt los yog Merge: Ib txoj kev peb-txoj kev valve los yog ntau txoj kev valve yog siv rau diverting los yog merging.

2.3 Qhov loj ntawm lub valve

Yeeb Nkab Loj: Lub valve loj yuav tsum phim cov yeeb nkab loj kom ntseeg tau tias cov dej ntws zoo. Cov kev xav tau ntws: Qhov loj ntawm lub valve yuav tsum tau ua kom tau raws li qhov kev xav tau ntawm lub cev, thiab qhov loj lossis me dhau yuav cuam tshuam rau kev ua haujlwm. Installation Space: Kev teeb tsa qhov chaw tuaj yeem cuam tshuam qhov kev xaiv qhov loj ntawm lub valve.

2.4 Resistance poob ntawm valve

Kev poob siab: Lub valve yuav tsum txo qis qis kom tsis txhob cuam tshuam kev ua haujlwm ntawm lub cev.

Flow channel tsim: Tag nrho bore li qub, xws li tag nrho bore pob li qub, txo qis poob.

Valve Hom: Qee lub li qub, xws li npauj npaim li qub, muaj kev tiv thaiv tsawg dua thaum qhib, ua rau lawv haum rau lub sijhawm qis qis.

2.5 Qhov kub thiab txias ua haujlwm ntawm lub valve

Qhov kub thiab txias: cov khoom siv valve yuav tsum tau hloov mus rau qhov kub thiab txias, thiab cov ntaub ntawv kub-resistant yuav tsum tau xaiv nyob rau hauv qhov kub thiab txias ib puag ncig.

Qib siab: Lub valve yuav tsum muaj peev xwm tiv taus qhov siab tshaj plaws ua haujlwm ntawm lub cev, thiab lub siab-siab system yuav tsum xaiv lub valve nrog lub siab siab.

Kev sib xyaw ua ke ntawm qhov kub thiab txias: qhov kub thiab txias ib puag ncig yuav tsum xav txog tshwj xeeb ntawm cov khoom siv zog thiab cov khoom sib khi.

2.6 Cov khoom siv ntawm lub valve

Corrosion resistance: Xaiv cov khoom tsim nyog raws li cov kua dej corrosiveness, xws li stainless hlau, Hastelloy, thiab lwm yam.

Mechanical zog: Cov khoom siv valve yuav tsum muaj lub zog txhua yam txaus los tiv thaiv kev ua haujlwm siab.

Kub adaptability: Cov khoom yuav tsum tau hloov mus rau qhov ua hauj lwm kub, qhov kub thiab txias ib puag ncig xav tau cov ntaub ntawv kub-resistant, thiab qhov kub-kub ib puag ncig xav tau cov ntaub ntawv txias-resistant.

Economy: Nyob rau ntawm qhov chaw ua tau raws li qhov yuav tsum tau ua, xaiv cov khoom siv nrog kev lag luam zoo dua.
