ʻEhiku ʻano o ka flange sealing surfaces: piha ka maka FF, hāpai ʻia ka maka RF, hāpai ʻia ka maka M, concave alo FM, tenon alo T, groove alo G, a apo apo alo alo RJ.
I waena o lākou, hoʻohana nui ʻia ka mokulele FF a me ka convex RF, no laila ua hoʻolauna ʻia lākou a ʻike ʻia i nā kikoʻī.
FF maka piha
ʻO ke kiʻekiʻe o ka ʻili pili o ka flange palahalaha (FF) ua like ia me ka laina hoʻohui bolt o kaflange. Hoʻohana ʻia kahi gasket maka piha, maʻamau maʻamau, ma waena o ʻeluanā lau palahalaha.
ʻO ka maka paʻa maka piha ke ʻano sealing ili he palahalaha loa, kūpono ia no nā manawa me ka haʻahaʻa haʻahaʻa a me ka mea ʻawaʻawa ʻole.
Ua hāpai ʻo RF i ka maka
Hiki ke ʻike maʻalahi ʻia nā flanges maka hoʻokiʻekiʻe (RF) no ka mea aia ka ʻili o ka gasket ma luna o ka laina bolted o ka flange.
ʻO ka ili hoʻopaʻa ʻano maka hoʻokiʻekiʻe ka mea i hoʻohana nui ʻia ma waena o nā ʻano ʻehiku. ʻO nā kūlana o ka honua, nā ʻōnaehana ʻEulopa a me nā kūlana kūloko a pau nā kiʻekiʻe paʻa. Eia naʻe, ma
ʻO nā flanges maʻamau o ʻAmelika, pono e hoʻomaopopo ʻia ʻo ke kiʻekiʻe o ke kaomi kiʻekiʻe e hoʻonui i ke kiʻekiʻe o ka ʻili o ka sila. Nui nō hoʻi nā ʻano gaskets.
RF gaskets no ka hoʻokiʻekiʻe alo sealing alo flanges e loaʻa nā ʻano like ʻole metalalic flat gaskets a me nā gaskets wahī ʻia; ʻO ke kīʻaha metala i wili ʻia, ka pahu ʻeha spiral (me ke apo o waho a i ʻole
apo), etc.
ʻokoʻa
Ke kaomi oFF piha maka pihaliʻiliʻi maʻamau, ʻaʻole ma mua o PN1.6MPa. ʻO ka ʻāpana hoʻopili sila ʻana o ka flange maka piha piha o FF he nui loa, a he nui loa nā ʻāpana ma waho o ka laulā o
ili hoʻopaʻa maikaʻi. ʻAʻole hiki ke hoʻopili maikaʻi ka ʻili o ka sila, no laila ʻaʻole maikaʻi ka hopena sealing. He liʻiliʻi ka wahi hoʻopili o ka maka flange sealing surface, akā
hana wale nō i loko o ka laulā o ka ili hoʻopaʻa pono, no ka mea, ʻoi aku ka maikaʻi o ka hopena sealing ma mua o ka flange alo piha.
