Peb paub tias cov khoom lag luam desulfurization npauj npaim valve yog cov khoom lag luam npauj npaim valve uas yuav tsum tau ua raws li qhov yuav tsum tau muaj kev tiv thaiv corrosion, hnav tsis kam, txaus tus nqi, thiab cov kev cai kub sib xws, yog li kev xaiv ntawm nws cov khoom tseem ceeb heev. Yog li dab tsi cov khoom siv rau desulfurization npauj npaim valve? Tom ntej no, cia peb qhia ntxaws ntxaws rau peb cov phooj ywg.
Cov khoom siv ntawm lub cev valventawm desulfurization npauj npaim li qub tau muab faib ua: ductile hlau, cam khwb cia hlau, stainless hlau, thiab lwm yam. Los ntawm kev xav ntawm cov nqi tsim khoom, feem ntau yog xaiv cov hlau ntau dua. Yog hais tias nyob rau sab qaum teb, vim muaj ntau yam xws li huab cua thiab qhov kub thiab txias, lub valve lub cev cov khoom yuav tsum tau cam khwb cia hlau los yog saum toj no.
Lub rooj zaum valventawm desulfurization npauj npaim li qub feem ntau yog cov roj hmab, thiab cov khoom siv hauv ob sab phlu tam sim no yog EPDM (ethylene propylene diene monomer roj hmab).
Cov khoom siv ntawm lub valverau desulfurization npauj npaim li qub tuaj yeem xaiv tau: cov hlau nplaum, 304 stainless hlau, hlua nrog EPDM roj hmab, 1.4529, 2507 duplex stainless hlau, thiab lwm yam ntaub ntawv.
Rau desulfurization npauj npaim li qub siv hauv cov kav dej thiab cov kav dej ntws, cov khoom siv ntawm lub valve tuaj yeem ua cov hlau tsis zoo lossis 304 stainless hlau.
Lub desulfurization npauj npaim valve cov khoom siv nyob rau hauv cov txiv qaub slurry nruab nrab pipelines feem ntau yog ua los ntawm 2507 thiab 1.4529 duplex stainless hlau.
Txoj kev sib txuas ntawm desulfurization npauj npaim li qub feem ntau suav nrog hom wafer thiab flange kev twb kev txuas. Cov kab me me desulfurization npauj npaim li qub feem ntau yog siv wafer hom kev sib txuas, nrog lub cheeb ntawm DN50 thiab DN450. Rau desulfurization npauj npaim li qub nrog txoj kab uas hla tshaj DN500, nws raug nquahu kom siv flange txuas.
