Lub npauj npaim valve siv rau tus kais dej kub?

Npauj Npaim Valve valve tuaj yeem siv rau cov kais dej kub yuav tsum tau raug suav nrog cov khoom siv dej hiav txwv ntev, tsis yog siv rau cov khoom siv dej ntev li qub, Tshwj xeeb tsim kev kub siab muag npauj npaim li qub lossis hlau foob npauj npaim li qub, tab sis tus nqi thiab sib xyaw yuav tsum muaj kev sib npaug. Qhov kev tsom xam tshwj xeeb yog raws li hauv qab no:
1.Hub foob npauj npaim valve: haum rau dej kub kav dej
{- Rico Foob Npauj Npaim Li Qub Siv Hlau (xws li Stainless Hlau (uas yog muab ntim rau ntawm qhov chaw sib ze, uas tau sib khi los ntawm kev sib cuag ntawm nruab nrab thiab hlau. Cov ntsiab lus muaj xws li:
Cov dej kub siab kuj: Cov hlau sealing nto tuaj yeem tiv thaiv cov dej kub (xws li saum toj no 150}}}}} kev siv tsis yooj yim los yog laus.
Lub neej ntev kev pabcuam: piv nrog cov muag muag npauj npaim li qub,
Siv dav: nws tuaj yeem siv rau hauv liaj teb chaws hauv nroog loj, lag luam kub ncig thiab yog li ntawm, thiab ua kom tau raws li kev xav tau ntawm cov dej kub ntws tswj.
Cov xwm txheej ib txwm:
HARDRAULED NPLOOJ YUAV TSUM TAU SIV RAU KEV HLAU KUB KUB RAU HAUV KUB KUB HAUV INRBAN Central Cua Sov Tshuab. Lawv cov qauv hlau khi tuaj yeem tiv thaiv cov dej kub ntawm 80-150 degrees Celsius tau ntev. Hauv kev muaj cov dej dej kub, lub foob pob hluav taws xob tsis muaj zog yuav tiv thaiv cov hlau tshuab hluav taws xob hauv dej kub, yog li ua kom muaj kev ntseeg tau ntawm lub foob.
2. Mos Coob Npauj Npaim Li Qub: Ceev faj thaum siv hauv dej kub
Mos Sealing Npauj Npaim li qub yog muab ntim nrog roj hmab (piv txwv li cov roj hmab nitrile, EPDM) lossis fluorinated plastics (piv txwv li polytetrostorauruoroethylene). Nws cov kev txwv yog:
Cov Khoom Siv Roj Hmab:
Cov roj hmab li qub muaj qhov kub tsis kam ntawm nruab nrab ntawm-20 degree, tab sis raws li kev siv dej kub (piv txwv li ntawm 70 qib.
Cov dej kub raug rau cov dej kub tuaj yeem ua rau cov roj hmab kom tawv tawv, tawg thiab txawm tias poob tawm, ua rau muaj kev txi.
Tus nqi thiab thiav:
High - cov roj hmab tiv thaiv roj hmab, xws li cov roj hmab uas tsis tshua muaj zog thiab muaj ntau dua cov khoom siv luv luv dua li nyuaj- Ciam Npauj Npaim li qub.
Hauv cov ntawv thov kub, muag - Ciam Npaim yuav tsum tau muab cov nqi hloov tsis tu ncua, ua rau cov nqi txij nkawm. Muaj feem cuam tshuam cov xwm txheej:
Npauj npaim li qub nrog kub resistant roj hmab ntsaws ruaj ruaj rau kev siv luv lossis sib txawv dej kub, xws li kev kuaj dej kub dej.
Mos Sealing Npauj Npaim li qub yuav yog kev xaiv tau nyiaj txiag rau cov ntawv thov kub kub (piv txwv li ntau dua li 70 degree) thiab tsis tshua muaj kev sib luag.
III. Kub Dej Kais Hlau Valve Xaiv cov lus pom zoo
Hard Foob yog qhov nyiam:
Cov dej kub kub tau qhib thiab tawm, thiab nyuaj {} liew- pob zeb sib thooj uas muaj cov abrasive ntxiv thiab ntev dua.
Piv txwv li, hauv cov dej kub hauv tsev, tawv tawv - Sealed pob kev ua tau zoo thiab tus nqi tswj qis dua li Npauj Npaim li qub.
Zam kev ntev ntev ntawm cov mos mos -} CIA SOLDEFE Npaim Npaim li qub rau dej kub:
Yog tias daim ntaub muag muag npauj npaim li qub, xaiv cov roj hmab kub siab tiv taus roj hmab thiab tshuaj xyuas lub foob tsis tu ncua.
Piv txwv li, hauv cov kav dej kub rau kev lag luam kub, muag- Ciam Yuav Tsum Saib Xyuas kom tiv thaiv cov roj hmab tsis ua haujlwm kom tiv thaiv cov roj hmab tsis ua haujlwm.
Xav Txog Cov Dej Kub Dag:
Cov kais dej kub tuaj yeem siv lub valve tshwj xeeb (xws li ceramic valve kwjet). Nws cov khoom siv sealing (xws li ceramics) yog cua sov thiab hnav tiv taus, thiab ntau dua haum rau kev ua haujlwm ntev-}}}}}}}} tsav dej kub. Cov Hluav Taws Xob Hluav Taws Xob, piv txwv, muaj cov pa hluav taws xob, muaj cov khoom siv hluav taws xob ceramic uas tuaj yeem tiv thaiv cov cua sov tsim los ntawm cov cua sov instantaneous thiab muab cov khoom sib khi uas ruaj khov.
