Cov kav dej kub yog ib feem tseem ceeb ntawm peb lub neej txhua hnub. Lawv muab dej kub rau peb chav dej, chav ua noj, thiab lwm yam hauv cov kav dej kub, cov li qub ua lub luag haujlwm tseem ceeb. Lawv tuaj yeem tswj tau qhov ntws, siab, thiab kub ntawm cov dej kub. Yog li, hom valve twg yog siv rau cov kav dej kub?
Thaum xaiv lub raj xa dej kub, thawj qhov yuav tsum tau xav txog yog nws qhov kub tsis kam. Txij li cov dej kub ntws hauv cov kav dej, li qub yuav tsum tiv taus qhov kub thiab txias. Yog li ntawd, stainless hlau li qub yog ib qho kev xaiv. Stainless hlau li qub muaj cov yam ntxwv ntawm qhov kub thiab txias, tiv thaiv corrosion, sealing zoo, thiab lwm yam, thiab tuaj yeem hloov mus rau qhov chaw siv cov kav dej kub.
Tsis tas li ntawd, cov kav dej kub hauv cov kav dej kuj yuav tsum muaj kev tswj xyuas zoo. Kev khiav, siab thiab kub ntawm cov dej kub yuav tsum tau kho thiab tswj los ntawm li qub, yog li kev tswj hwm ntawm lub valve yog qhov tseem ceeb. Cov khoom siv tswj tau muaj xws li pob li qub, npauj npaim li qub thiab hluav taws xob tswj li qub. Pob li qub yog tsim rau cov kav dej me me thiab cov tshuab tsis tshua muaj siab. Lawv muaj cov yam ntxwv ntawm kev qhib thiab kaw nrawm thiab ua haujlwm yooj yim. Npauj npaim li qub yog qhov zoo tagnrho rau cov kav dej me me thiab nruab nrab thiab muaj cov yam ntxwv ntawm cov kua dej me me thiab yooj yim qhib thiab kaw. Hluav taws xob tswj li qub yog tsim rau cov kav dej loj loj uas xav tau kev tswj xyuas meej. Lawv muaj cov yam ntxwv ntawm kev hloov kho dav dav thiab kev tswj xyuas qhov tseeb.
Tsis tas li ntawd, cov kav dej kub hauv cov kav dej kuj yuav tsum xav txog kev nyab xeeb kev ua haujlwm. Cov dej kub cuam tshuam rau tib neeg kev nyab xeeb thiab kev noj qab haus huv, yog li lub valve yuav tsum muaj kev tiv thaiv kev nyab xeeb. Piv txwv li, lub anti-backflow valve tuaj yeem tiv thaiv qhov thim rov qab ntawm cov dej kub thiab tiv thaiv cov dej kub los ntawm kev sib kis ntawm cov dej txias. Lub overflow valve tuaj yeem tiv thaiv cov raj xa dej ntau dhau thiab tiv thaiv kev nyab xeeb ntawm cov kav dej. Cov kev nyab xeeb li qub no tuaj yeem ua kom muaj kev nyab xeeb ntawm cov dej kub thiab tsis txhob muaj xwm txheej.
Los ntawm txoj kev, qhov twg valve siv rau cov kav dej kub yog nyob ntawm ntau yam. Ua ntej, lub valve yuav tsum muaj cua sov-resistant thiab tiv taus kub thiab corrosion. Qhov thib ob, lub valve xav tau kev tswj xyuas zoo thiab kev tswj hwm ntawm cov dej kub ntws, siab, thiab kub. Thaum kawg, cov li qub tseem xav tau kev nyab xeeb kev ua haujlwm kom muaj kev nyab xeeb ntawm cov dej kub. Cov kav dej kub yuav tsum raug xaiv raws li ib puag ncig siv tshwj xeeb thiab xyuas kom muaj kev siv txhua hnub thiab kev ruaj ntseg ntawm cov dej kub.
