1. Tsa ntsej muag (RF):
Cov nplaim yog lub dav hlau du thiab tseem tuaj yeem muaj cov zerrated zawj. Cov qauv sib tsoo muaj cov qauv yooj yim, yog qhov yooj yim rau kev tsim khoom, thiab yog qhov tsim nyog rau kev tiv thaiv corrosion corrosion. Txawm li cas los xij, hom kev sib khi no muaj qhov chaw loj loj muaj qhov chaw sib cav loj, ua rau muaj kev phom sij ua kom nruj, uas ua rau nws tsis yooj yim ua kom tiav.
2. Txiv neej-Poj Niam (MFM):
Kev sib khi saum npoo muaj cov convex thiab concave nto uas haum ua ke. Ib lub gasket yog muab tso rau ntawm qhov sib txawv concave, tiv thaiv cov gasket los ntawm kev extruded. Yog li ntawd, nws yog tsim nyog rau cov ntawv thov siab siab.
3. Tus nplaig thiab Groove (TG):
Kev sib khi saum npoo av yog tsim ntawm cov nplaig thiab zawj thiab cov pa roj tso rau hauv cov zawj. Nws tiv thaiv cov gasket los ntawm kev tsiv chaw. Cov gaskets me me tuaj yeem siv, ua rau muaj cov ntsia hauv siab qis dua rau cov compression. Cov qauv tsim no yog ua tau zoo rau kev ua tiav lub foob zoo, txawm tias muaj cov kev mob siab. Txawm li cas los xij, cov drawback yog tias cov qauv thiab cov txheej txheem tsim kev tsim qauv yog qhov sib xyaw ua ke, thiab hloov cov gasket rau hauv cov zawj muaj qhov nyuaj. Ib qho ntxiv, feem ntawm cov xov xwm tshwj xeeb ua rau puas tsuaj, yog li ntawv ceev faj yuav tsum tau ua thaum sib dhos, tshem tawm, lossis kev thauj mus los. Tus nplaig thiab cov zawj frealing cov nplaim yog haum rau cov nplaim, tawg, tshuaj lom, thiab cov ntawv thov siab. Txawm hais tias nrog lub cheeb tsam loj dua, lawv tseem tuaj yeem muab lub foob thaum lub siab tsis siab dhau.
4. Saky Steel puv ntsej muag (FF) thiabNtiv nplhaib sib koom tes (RJ):
Tas nrho cov ntsej muag sib khi yog qhov haum rau cov ntawv thov cov kev siv hluav taws xob tsawg (PNT≤ 1.6MPA).
Ntiv nplhaib sib xyaw ua ke feem ntau yog siv rau caj dab-welded flanges thiab kev sib xyaw ua ke, haum rau siab yog li cas (6.3MPA).
Lwm yam ntawm Saleing Surfaces:
Rau cov hlab ntsha high-siab thiab cov xov hluav taws xob siab siab, conical sealing chaw lossis trapezoidal zuaj zeem muag tuaj yeem siv tau. Lawv tau ua khub nrog cov roj hlau sib xyaw hlau (Lens Gaskets) thiab hlau gaskets nrog elliptical lossis octagonal-ntu, feem. Cov chaw sealing no yog tsim nyog rau cov ntawv thov kev siab siab tab sis yuav tsum muaj qhov siab ntev thiab qhov sib tw kom nyuaj, ua rau lawv nyuaj rau lub tshuab.
