Vertical Stainless Hlau Check Valve
Lift type check valve
GB / T12235 tsim, bolted valve bonnet, nqa valve disc
Txheej txheem cej luam
Kos valve yog hais txog lub valve uas nws qhib thiab kaw qhov chaw yog cov voj voog ncig thiab tso siab rau lawv tus kheej qhov hnyav thiab nruab nrab siab los ua kom thaiv qhov rov qab ntws ntawm qhov nruab nrab. Nws belongs rau pawg valve tsis siv neeg, tseem hu ua check valve, ib-txoj kev valve, rov qab valve los yog cais valve. Lub zog hom ntawm lub valve disc tau muab faib ua hom nqa thiab viav vias hom. Cov qauv ntawm lub tshuab nqa lub valve zoo ib yam li lub ntiaj teb valve, tshwj tsis yog tias nws tsis muaj lub valve qia uas tsav lub valve disc. Qhov nruab nrab ntws los ntawm qhov kawg inlet (sab qis) thiab ntws tawm ntawm qhov hluav taws xob kawg (sab sauv). Thaum lub siab nkag siab ntau dua qhov sib npaug ntawm qhov hnyav ntawm lub valve disc thiab nws cov dej tsis kam, lub valve qhib. Ntawm qhov tsis sib xws, lub valve raug kaw thaum nruab nrab ntws rov qab. Lub viav vias kos valve muaj qhov inclined disc uas tuaj yeem tig ib ncig ntawm nws qhov axis, thiab nws txoj haujlwm ua haujlwm zoo ib yam li lub tshuab nqa nqa. Kos li qub feem ntau siv los ua ko taw li qub hauv cov twj siv dej los tiv thaiv cov dej rov qab. Kos li qub thiab nres li qub yog siv ua ke los muab kev sib cais zoo. Qhov tsis zoo yog qhov tsis kam yog qhov loj thiab lub sealing tsis zoo thaum kaw.
Kev xaiv cov qauv rau cov tshev valve
1. Txhawm rau tiv thaiv qhov rov qab ntawm qhov nruab nrab, cov tshev valve yuav tsum tau nruab rau ntawm cov khoom siv, cov khoom siv thiab cov kav dej;
2. Kos li qub feem ntau haum rau cov xov xwm huv si thiab tsis haum rau cov xov xwm uas muaj cov khoom siv thiab cov viscosity siab;
3. Feem ntau, kab rov tav nqa daim tshev li qub yuav tsum tau siv rau cov kav dej kab rov tav nrog lub nominal txoj kab uas hla ntawm 50mm;
4. Qhov ncaj-dhau ntawm nqa daim tshev valve tuaj yeem ntsia tau rau ntawm cov kav dej kab rov tav xwb;
5. Rau cov dej twj tso kua mis inlet pipeline, yuav tsum tau siv lub valve hauv qab. Lub hauv qab valve feem ntau tsuas yog ntsia rau ntawm cov yeeb nkab ntsug ntawm lub twj tso kua mis inlet, thiab qhov nruab nrab ntws los ntawm hauv qab mus rau saum;
6. Hom lifting muaj kev sib khi zoo dua thiab ua kom muaj dej ntau dua li lub viav vias hom. Hom kab rov tav yuav tsum tau muab ntsia rau ntawm cov kav dej kab rov tav, thiab hom ntsug yuav tsum tau muab ntsia rau ntawm cov kav dej ntsug;
7. Lub installation txoj hauj lwm ntawm lub viav vias kos valve tsis txwv. Nws tuaj yeem ntsia tau rau ntawm kab rov tav, ntsug lossis inclined pipelines. Yog hais tias nws yog ntsia rau ntawm ib tug ntsug raj, qhov nruab nrab ntws kev taw qhia yuav tsum yog los ntawm hauv qab mus rau sab saum toj;
8. Lub viav vias kos valve yuav tsum tsis txhob ua rau hauv lub valve me me. Nws tuaj yeem ua rau kev ua haujlwm siab heev. Lub nominal siab tuaj yeem ncav cuag 42MPa, thiab lub nominal txoj kab uas hla tuaj yeem loj heev, mus txog 2000mm lossis ntau dua. Nyob ntawm cov ntaub ntawv ntawm lub plhaub thiab cov ntsaws ruaj ruaj, nws tuaj yeem siv rau txhua qhov chaw ua haujlwm thiab txhua qhov chaw ua haujlwm kub. Qhov nruab nrab yog dej, chav, roj, nruab nrab corrosive, roj, tshuaj, thiab lwm yam. Qhov kub thiab txias ntawm qhov nruab nrab yog nyob nruab nrab ntawm -196--800 degree;
9. Lub viav vias kos valve yog tsim rau qhov tsis tshua muaj siab thiab txoj kab uas hla loj, thiab qhov chaw teeb tsa raug txwv;
10. Lub installation txoj hauj lwm ntawm npauj npaim kos valve tsis txwv thiab tuaj yeem ntsia tau rau ntawm cov kav dej kab rov tav, lossis ntawm cov kav dej ntsug lossis inclined;
