¢Ù Te whakataki o te peeke
Ko te polytetrafluoroethylene (PTFE) te peeke kapi he ahua o te urunga hiato-kore, e rua nga waahanga: te uhi me te whakauru. Ko te mahi matua o te envelope he anti-corrosion, he mea hanga ki te polytetrafluoroethylene. Ko te whakauru (whakakii) he mea whakarewa-kore me te whakakaha whakarewa ranei, he mea hanga mai i te pepa rapa asbestos.
Polytetrafluoroethylene (PTFE) tarapēke gasket he te nuinga e tika ana mo te katoa rererangi me te mata whakarewa hononga flange paipa maitai. He pai mo te reo kino me te PN whakaingoa o te 0.6 ~ 5.0mpa me te pāmahana mahi o 0 ~ 150 ¡æ ranei te reo me nga whakaritenga maemaa teitei.
¢Ú Te ahua o te peera
Polytetrafluoroethylene (PTFE) gasket mo flange putorino e taea te wehea ki toru momo rite ki te tikanga hanga: momo tapahi (s momo), momo machining (momo M) me te momo whakakopa (momo F).
Mo te peeke whakakakahu miihini, ka rite te diameter o roto o te paparanga ki te diameter o roto o te flange, kia kore ai e rere te rere o te wai i te flange. Ko te peeke takai takai, he mea hanga ki te 0.4-0.8 mm te matotoru polytetrafluoroethylene (PTFE) kiriata. Whai muri i te hiri wera, ka takai nga pito e rua o te peera ki waho o nga mea matua annular ki te ahua U. He ngawari ki te hanga me te pai mo te hiri piriti nui.
