1. Cov qauv tsim qauv sib txawv
| Ntaus | Flange Npauj Npaim Valve | Lug Npauj Npaim Valve |
|---|---|---|
| Kev sib txuas qauv | Lub valve lub cev tuaj nrog flange tag nrho, uas tau ncaj qha nrawm rau cov yeeb nkab flange los ntawm bolts | Lub cev lub cev muaj pob ntseg tawm tsam (cov hlua) ntawm ob sab, thiab pob ntseg muaj los ntawm qhov lossis cov qhov threaded |
| Bolt Layout | Bolts nkag mus rau lub valve flange thiab yeeb nkab flange rau daim ntawv clamp | Phua kho: luv bolts txuas cov kav dej ntawm ob sab ntawm nws tus kheej tsis muaj dhau los ntawm lub cev valve |
| Sealing nto nyob rau hauv siab | Cov bolts nyem lub cev valve, thiab siv ntev yuav ua rau muaj kev cuam tshuam ntawm cov chaw sib khi | Bolts tsuas ruaj ntseg cov nyom, tiv thaiv kev tiv thaiv ntawm kev sib khi saum npoo thiab txuas ntxiv lub neej |
2. Txhim kho thiab txij nkawm nta
Flange Npauj Npaim Valve Installation:
Dlhos lub valve thiab yeeb nkab flange qhov thiab ruaj ntseg nrog cov bolts ntev.
Qhov tsis zoo: Txawb tawm tsam yuav tsum tau tshem cov bolts los ntawm cov kav dej ib txhij, ua kom muaj kev ywj pheej tsis yooj yim.
Lugged Npauj Npaim Valve Nruab Nrab:
Threaded lub hom (mainstream): luv bolts ntsia hlau rau hauv lub di xov rau ntawm tus kheej sab xis ib sab ntawm cov yeeb nkab.
Hom tau txais txiaj ntsig: Tso cai tshem tawm ib sab ntawm cov yeeb nkab (piv txwv li, rau kev kho) tsis muaj lub valve poob.
Siv cov ntawv thov: raj xa hluav taws xob xaus, thiab lwm qhov chaw uas nquag disassembly thiab kev sib dhos.
3. Kev Ua Haujlwm thiab Kev Lag Luam Kev Lag Luam
| Cov khoom |
Flange Npauj Npaim Valve |
Lug Npauj Npaim Valve |
|---|---|---|
| Ruaj khov | Hight (Feem Flace Flanged Qauv) | The thread o qhov muaj tib lub ruaj khov raws li hom flange |
| Kev Ntsuas Hluav Taws Xob | High (Pn10-PN40) | Nruab Nrab (PN6-PN16) |
| Tus nqi | Siab dua (suav nrog flange thiab ntau cov ntaub ntawv hlau) | Qis dua flange hom, siab dua wafer hom |
4. Cov ntaub ntawv raug cai
(Ntxig Daim Ntawv Teev Npe Thov Tso Cai Ntawm No: Tshuaj tua hluav taws, hluav taws tiv thaiv cov yeeb nkab tes hauj lwm, cov khoom noj ntau lawm, thiab lwm yam)
Flanged Npauj npaim li qub yog nyiam rau:
High-pressure (>PN16), High-ntws chav / Roj / Roj / Roj Roj;
Cov kav dej tsau yuav tsum tau saib xyuas ntev ntev.
Lug Npauj Npaim Li Qub yog nyiam rau:
Nruab nrab- thiab qis-siab (tsawg dua los yog sib npaug rau pn16) cov xov xwm corrosive (xws li cov kua qaub thiab cov roj av alkali);
Cov xwm txheej yuav tsum muaj ib leeg-tog disassembly, xws li rau qhov xaus soj ntsuam chaw nres nkoj thiab cov cuab yeej sim;
Chaw-txwv cov chaw (threaded lub qhov muaj ntau muaj ntau cov installation)
