1. Tsa ntsej muag (RF):
Qhov saum npoo yog lub dav hlau du thiab tuaj yeem muaj serrated grooves. Lub sealing nto muaj cov qauv yooj yim, yooj yim rau kev tsim khoom, thiab haum rau kev tiv thaiv corrosion hauv ob sab phlu. Txawm li cas los xij, hom sealing nto no muaj qhov sib txuas loj ntawm gasket, ua rau nws yooj yim rau gasket extrusion thaum ua ntej nruj, uas ua rau nws nyuaj rau kev ua kom zoo compression.
2. Txiv neej- Poj Niam (MFM):
Lub sealing nto yog convex thiab concave nto uas haum ua ke. Lub gasket muab tso rau ntawm qhov chaw concave, tiv thaiv lub gasket los ntawm extruded. Yog li ntawd, nws yog haum rau high-pressure daim ntaub ntawv.
3. Tus nplaig thiab Groove (TG):
Lub sealing nto yog tsim los ntawm tus nplaig thiab grooves, nrog cov gasket tso rau hauv qhov zawj. Nws tiv thaiv lub gasket los ntawm kev hloov chaw. Cov gaskets me me tuaj yeem siv tau, uas ua rau lub zog qis qis uas yuav tsum tau ua rau compression. Qhov kev tsim no muaj txiaj ntsig zoo rau kev ua tiav lub foob zoo, txawm tias nyob rau hauv cov xwm txheej siab. Txawm li cas los xij, qhov tsis zoo yog tias cov qauv thiab cov txheej txheem tsim khoom yog qhov nyuaj, thiab kev hloov cov gasket hauv qhov zawj tuaj yeem nyuaj. Tsis tas li ntawd, qhov seem ntawm tus nplaig tuaj yeem raug puas tsuaj, yog li yuav tsum tau ceev faj thaum sib dhos, disassembly, lossis tsheb thauj mus los. Tus nplaig thiab zawj sealing qhov chaw yog tsim rau cov nplaim taws, tawg, muaj kuab lom, thiab cov ntawv thov siab. Txawm tias muaj txoj kab uas hla loj dua, lawv tseem tuaj yeem muab lub foob zoo thaum lub siab tsis dhau.
4. Saky Steel Full Face (FF) thiabLub nplhaib sib koom (RJ):
Tag nrho lub ntsej muag sealing yog tsim rau cov ntawv thov uas tsis tshua muaj siab (PN ≤ 1.6MPa).
Lub nplhaib sib koom ua ke feem ntau yog siv rau caj dab-welded flanges thiab ib qho flanges, haum rau qhov siab siab (6.3MPa ≤ PN ≤ 25.0MPa).
Lwm Hom Sealing Surfaces:
Rau cov hlab ntsha siab thiab cov kav dej muaj zog, cov khoom siv sib khi ntawm cov khoom siv los yog cov khoom siv trapezoidal groove sealing tuaj yeem siv tau. Lawv tau ua ke nrog cov hlau kheej kheej (lens gaskets) thiab cov khoom siv hlau nrog elliptical lossis octagonal cross-section, feem. Cov sealing saum npoo no yog tsim rau cov ntawv thov siab, tab sis yuav tsum muaj qhov tseeb qhov tseeb thiab qhov chaw tiav, ua rau lawv nyuaj rau tshuab.
