Kev kho dej khib nyiab hauv kev lag luam yog ib qho tseem ceeb thiab txoj haujlwm nyuaj hauv kev tiv thaiv ib puag ncig, uas tseem tso tseg cov kev cai tshwj xeeb rau kev xaiv cov li qub. Hauv kev kho cov dej khib nyiab, cov li qub yuav tsum muaj corrosion-resistant, kaw, thiab yoog raws qhov sib txawv, qhov kub thiab txias. Yog li ntawd, xaiv cov khoom siv valve yog qhov tseem ceeb los xyuas kom meej thiab ruaj khov ntawm kev kho dej khib nyiab. Yog li, dab tsi li qub siv hauv kev kho dej khib nyiab?
Cov dej khib nyiab feem ntau muaj ntau yam khoom corrosive, tshuaj thiab cov khoom siv. Cov khoom xyaw no txwv nruj rau cov khoom siv valve. Cov khoom siv valve feem ntau hauv kev kho dej khib nyiab muaj xws li stainless hlau, fluoroplastics, thiab lwm yam.
1. Stainless hlau yog ib qho khoom siv thiab tseem ceeb rau kev kho dej khib nyiab li qub. Nws muaj kev tiv thaiv corrosion zoo heev thiab txhua yam muaj zog thiab tuaj yeem tiv taus kev yaig ntawm ntau yam tshuaj hauv dej khib nyiab. Tshwj xeeb tshaj yog thaum kho cov dej khib nyiab uas muaj cov tshuaj acidic lossis alkaline, stainless hlau li qub ua tau zoo heev los xyuas kom lub sijhawm ua haujlwm ruaj khov ntawm lub cev. Feem ntau siv stainless hlau li qub rau kev kho dej khib nyiab muaj xws li npauj npaim li qub, steel rooj vag li qub, thiab cov lim dej.
2. Vim tias cov khoom siv fluoroplastic muaj kev tiv thaiv corrosion zoo, yog lub teeb yuag, thiab tus nqi qis, nws kuj tau siv dav hauv kev kho dej khib nyiab. Cov ntaub ntawv yas muaj xws li polypropylene, Polyvinyl chloride, polytetrafluoroethylene, thiab lwm yam, thiab feem ntau siv fluorine-lined li qub rau cov dej khib nyiab muaj xws li fluorine-lined gate li qub, fluorine-lined npauj npaim li qub, fluorine-lined pob li qub, fluorine-lined nres li qub, thiab lwm yam. Lawv tuaj yeem hloov mus rau ntau qhov chaw dej khib nyiab thiab ua tiav cov txiaj ntsig kev lag luam tseem ceeb ntawm qee lub sijhawm tshwj xeeb.
Kev xaiv valve hauv qhov kev kho dej khib nyiab yuav tsum tau teeb tsa thiab xaiv raws li cov dej khib nyiab tshwj xeeb, txheej txheem kev kho thiab kev ua haujlwm. Los ntawm kev xav txog yam xws li kev tiv thaiv corrosion, cov khoom siv kho tshuab, thiab kev lag luam ntawm cov khoom siv valve, kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov dej khib nyiab tuaj yeem ua kom ntseeg tau, ua kom muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig.
