Kev txhim kho yav tom ntej ntawm stainless hlau npauj npaim valve
Stainless hlau npauj npaim li qub yog dav siv. Qhov ntau thiab ntau ntawm nws cov kev siv txuas ntxiv nthuav dav, thiab nws tab tom txhim kho mus rau qhov kub thiab txias, siab siab, txoj kab uas hla loj, sealing siab, lub neej ntev, kev hloov kho zoo heev, thiab ib lub valve nrog ntau lub zog. Nws txoj kev ntseeg siab thiab lwm yam kev ntsuas kev ua tau zoo tau mus txog qib siab. Nrog rau kev siv tshuaj corrosion-resistant hluavtaws roj hmab hauv npauj npaim li qub, kev ua haujlwm ntawm stainless hlau npauj npaim li qub tau txhim kho. Vim tias cov roj hmab hluavtaws muaj cov yam ntxwv ntawm kev tiv thaiv corrosion, yaig tsis kam, qhov ruaj khov, zoo resilience, yooj yim tsim, tsis tshua muaj nqi, thiab lwm yam., thiab hluavtaws roj hmab nrog kev ua tau zoo sib txawv tuaj yeem xaiv raws li kev siv sib txawv kom tau raws li kev siv ntawm npauj npaim li qub. . Txij li thaum polytetrafluoroethylene (PTFE) muaj zog corrosion kuj, ruaj khov kev ua tau zoo, tsis yooj yim rau lub hnub nyoog, tsis tshua muaj kev sib txhuam coefficient, yooj yim rau kev tsim, ruaj khov loj, thiab tuaj yeem sau thiab ntxiv nrog cov ntaub ntawv tsim nyog los txhim kho nws cov kev ua tau zoo, stainless hlau npauj npaim valve sealing. cov khoom siv nrog lub zog zoo dua thiab qis kev sib txhuam coefficient tuaj yeem tau txais, kov yeej cov kev txwv ntawm cov roj hmab hluavtaws. Yog li ntawd, cov ntaub ntawv siab molecular polymer sawv cev los ntawm polytetrafluoroethylene thiab nws cov khoom ntim thiab hloov kho cov ntaub ntawv tau siv dav hauv stainless hlau npauj npaim li qub, yog li ntxiv kev txhim kho kev ua haujlwm ntawm stainless hlau npauj npaim li qub thiab tsim stainless hlau npauj npaim li qub nrog qhov dav ntawm qhov kub thiab txias, txhim khu kev qha sealing. kev ua tau zoo thiab kev ua haujlwm ntev dua.
Nrog rau daim ntawv thov ntawm kub resistant, tsis kub resistant, muaj zog corrosion resistant, muaj zog yaig resistant thiab siab zog alloy cov ntaub ntawv nyob rau hauv stainless hlau npauj npaim li qub, hlau kaw stainless hlau npauj npaim li qub tau lug siv nyob rau hauv siab thiab tsis kub, muaj zog yaig, ntev. lub neej thiab lwm yam kev lag luam, thiab txoj kab uas hla loj (9 ~ 750mm), siab siab (42.0MPa) thiab qhov kub ntawm qhov dav (-196 ~ 606 ℃) stainless hlau npauj npaim li qub tau tshwm sim, nqa cov thev naus laus zis ntawm stainless hlau npauj npaim li qub rau ib qho tshiab qib.
Feem ntau stainless hlau faults
Cov roj hmab elastomer hauv npauj npaim valve yuav tsim kua muag, hnav, hnub nyoog, perforate lossis txawm poob thaum siv tas li. Cov txheej txheem kub vulcanization yog qhov nyuaj rau kev hloov kho raws li qhov xav tau ntawm kev kho ntawm qhov chaw. Cov cuab yeej tshwj xeeb yuav tsum tau siv los kho, uas siv cov cua sov thiab hluav taws xob ntau, thiab siv sijhawm ntev thiab siv zog ntau.
