¢Ù Hoʻolauna ʻana i ka pahu
ʻO ka polytetrafluoroethylene (PTFE) packing gasket he ʻano cushion composite non-metallic, i haku ʻia i ʻelua ʻāpana: ka uhi a me ka hoʻokomo. ʻO ka hana nui o ka envelopp he anti-corrosion, i hana mau ʻia me ka polytetrafluoroethylene. ʻO ka mea hoʻokomo (filler) he mea metala ʻole me ka hoʻoikaika metala ʻole, ka mea maʻamau i hana ʻia me ka asbestos rubber sheet.
ʻO ka polytetrafluoroethylene (PTFE) packing gasket ka mea kūpono no ka mokulele holoʻokoʻa a hoʻokiʻekiʻe i ke alo kila paipu flange pili. He kūpono ia no ka corrosive medium me ka nominal pressure PN o 0.6 ~ 5.0mpa a me ka mahana hana o 0 ~ 150 ¡æ a i ʻole medium me nā koi hoʻomaʻemaʻe kiʻekiʻe.
¢Ú Ke ʻano o ka pahu
Polytetrafluoroethylene (PTFE) gasket no ka paipu flange hiki ke hoʻokaʻawale ʻia i ʻekolu ʻano e like me nā ʻano hana: ʻoki ʻano (s type), machining type (M type) a me ke ʻano pelupili (F type).
No ka mīkini packing gasket, hiki ke kūlike ke anawaena o loko o ka papa packing me ke anawaena o loko o ka flange, i mea e pale ai i ka eddy au o ka wai ma ka flange. ʻO ka pahu pahu hoʻopili i hoʻopili ʻia, hana ʻia ia me ke kiʻiʻoniʻoni polytetrafluoroethylene (PTFE) mānoanoa 0.4-0.8 mm. Ma hope o ka hoʻopaʻa ʻana i ka wela, ua wahī ʻia nā ʻaoʻao ʻelua o ka gasket ma waho o ka mea annular core ma ke ʻano U. He maʻalahi ke hana a kūpono no ka hoʻopaʻa ʻana i ka flange nui.
