¢Ù Taw qhia ntawm gasket
Polytetrafluoroethylene (PTFE) packing gasket yog ib hom non-metallic composite cushion, uas feem ntau yog tsim los ntawm ob qhov chaw: lub hau thiab qhov ntxig. Lub luag haujlwm tseem ceeb ntawm lub hnab ntawv yog los tiv thaiv corrosion, uas feem ntau yog ua los ntawm polytetrafluoroethylene. Lub insert (filler) yog cov khoom siv tsis yog xim hlau nrog lossis tsis muaj hlau ntxiv, uas feem ntau yog ua los ntawm cov ntaub ntawv roj hmab asbestos.
Polytetrafluoroethylene (PTFE) packing gasket yog tsim rau tag nrho cov dav hlau thiab tsa lub ntsej muag steel yeeb nkab flange kev twb kev txuas. Nws yog haum rau corrosive nruab nrab nrog nominal siab PN ntawm 0.6 ~ 5.0mpa thiab ua hauj lwm kub ntawm 0 ~ 150 ¡æ los yog nruab nrab nrog siab huv si.
¢Ú Daim ntawv gasket
Polytetrafluoroethylene (PTFE) gasket rau yeeb nkab flange tuaj yeem muab faib ua peb hom raws li kev tsim khoom: txiav hom (s hom), machining hom (M hom) thiab folding hom (F hom).
Rau machined packing gasket, lub puab txoj kab uas hla ntawm lub packing txheej yuav ua tau raws li lub puab txoj kab uas hla ntawm lub flange, thiaj li yuav tiv thaiv lub eddy tam sim no ntawm cov kua ntawm lub flange. Raws li rau folded packing gasket, nws yog ua los ntawm 0.4-0.8 hli tuab polytetrafluoroethylene (PTFE) zaj duab xis. Tom qab cua sov sealing, ob qhov kawg ntawm lub gasket yog qhwv sab nraum lub annular core khoom nyob rau hauv U zoo. Nws yog ib qho yooj yim los tsim thiab haum rau loj flange sealing.
