¢Ù Gabatarwa na gasket
Polytetrafluoroethylene (PTFE) shirya gasket wani nau'i ne na matashin kushin da ba na ƙarfe ba, wanda gabaɗaya ya ƙunshi sassa biyu: murfin da abin sakawa. Babban aikin ambulan shine anti-lalata, wanda yawanci ana yin shi da polytetrafluoroethylene. Saka (filler) wani abu ne wanda ba na ƙarfe ba tare da ko ba tare da ƙarfafa ƙarfe ba, wanda yawanci ana yin shi da takardar roba na asbestos.
Polytetrafluoroethylene (PTFE) shirya gasket ne yafi dacewa da cikakken jirgin sama da tashe fuska karfe bututu flange dangane. Ya dace da matsakaici mai lalata tare da matsa lamba na PN na 0.6 ~ 5.0mpa da zafin aiki na 0 ~ 150 ¡æ ko matsakaici tare da buƙatun tsabta.
¢Ú Form na gasket
Polytetrafluoroethylene (PTFE) gasket ga bututu flange za a iya raba uku iri bisa ga masana'antu hanyoyin: yankan irin (s type), machining irin (M type) da kuma nadawa irin (F type).
Ga gasket ɗin da aka yi amfani da shi, diamita na ciki na marufi na iya zama daidai da diamita na ciki na flange, don hana ƙarancin halin yanzu na ruwa a flange. Amma ga folded packing gasket, an yi shi da 0.4-0.8 mm lokacin farin ciki polytetrafluoroethylene (PTFE) fim. Bayan rufewar zafi, duka ƙarshen gasket ɗin an nannade su a waje da ainihin abin da ke cikin siffar U. Yana da sauƙi don ƙirƙira kuma ya dace da babban rufewar flange.
