Kuaj li qubyuav tsum tau muab ntsia rau ntawm cov cuab yeej siv, cov khoom siv thiab cov kav dej txhawm rau txhawm rau tiv thaiv qhov nruab nrab countercurrent.
Qhov tsawg kawg nkaus qhib siab ntawm daim tshev valve yog 0.002-0.004mpa.
Kuaj li qubfeem ntau yog tsim nyog rau kev ntxuav cov xov xwm, tsis yog rau cov xov xwm uas muaj cov khoom siv thiab cov viscosity siab.
Covko taw valvefeem ntau yog ntsia rau ntawm txoj kab ntsug ntawm lub twj tso kua mis inlet, thiab qhov nruab nrab ntws los ntawm hauv qab mus rau saum.
Hom lifting muaj kev sib khi zoo dua li hom viav vias, thiab muaj cov kua dej loj dua.Kab rov tav hom yuav tsum tau ntsia rau hauv kab rov tav raj, thiab ntsug hom yuav tsum tau muab ntsia rau hauv txoj kab ntsug.
Kev txhim kho txoj haujlwm ntawm viav vias kos valve tsis txwv.Nws tuaj yeem ntsia tau rau hauv kab rov tav, ntsug lossis inclined pipelines.Yog tias ntsia rau hauv cov kav dej ntsug, qhov ntws ntawm qhov nruab nrab yuav tsum yog los ntawm hauv qab mus rau sab saum toj.
Lub rooj vag valveyuav tsum tsis txhob ua rau me me caliber li qub, thiab tuaj yeem ua rau kev ua haujlwm siab.Lub nominal siab tuaj yeem ncav cuag 42 MPa, thiab lub nominal txoj kab uas hla tuaj yeem loj, mus txog 2000 mm.Nws tuaj yeem siv rau txhua qhov kev ua haujlwm nruab nrab thiab txhua qhov kev ua haujlwm kub raws li cov khoom siv ntawm lub plhaub thiab foob.Qhov nruab nrab yog dej, chav, roj, corrosive nruab nrab, roj, tshuaj, thiab lwm yam. Qhov kev ua haujlwm kub ntawm qhov nruab nrab yog - 196 - 800 C.
Lub viav vias kos valve yog tsim rau qhov tsis tshua muaj siab thiab loj caliber, thiab nws qhov kev teeb tsa raug txwv.
Lub installation txoj hauj lwm ntawm wafer kos valve tsis txwv.Nws tuaj yeem ntsia tau rau hauv kab rov tav raj lossis hauv ntsug lossis inclined pipeline.
Pob check li qubyog tsim rau nruab nrab thiab tsis tshua muaj siab pipelines thiab yuav ua tau rau hauv loj caliber.
Lub plhaub khoom ntawm lub pob kos valve tuaj yeem ua los ntawm cov hlau tsis muaj steel, thiab lub hollow sphere ntawm lub foob tuaj yeem qhwv hauv PTFE engineering plastics.Yog li ntawd, nws kuj tseem siv tau rau hauv cov kav dej ntawm cov xov xwm corrosive.Kev ua haujlwm kub yog nyob nruab nrab ntawm - 101 - 150 C, lub nominal siab yog tsawg dua 4.0 MPa, thiab lub nominal pass range ntawm DN200 - DN1200.
Kuaj li qubyuav tsum tau ua raws li qhov loj me.Cov neeg muab khoom siv valve yuav tsum muab cov ntaub ntawv ntawm qhov ntau thiab tsawg xaiv kom pom qhov loj ntawm li qub thaum lawv qhib tag nrho ntawm tus nqi txaus.
