He pinepine nā hoaaloha i maopopo ʻole i ka pilina ma waena o nā kikoʻī o "DN", "Φ"a me """. I kēia lā, e hōʻuluʻulu wau i ka pilina ma waena o nā mea ʻekolu no ʻoe, me ka manaʻolana e kōkua iā ʻoe!
he aha ka ʻīniha"
ʻO ka ʻīniha (“) kahi anakahi kikoʻī i hoʻohana nui ʻia ma ka ʻōnaehana ʻAmelika, e like me nā paipu kila,nā kiwikā, nā flanges, nā kuʻekuʻe lima, nā pumps, nā tees, a me nā mea ʻē aʻe, e like me ke kikoʻī he 10″.
ʻĪniha (ʻīniha, i hoʻopōkole ʻia e like me in.) ʻo ia hoʻi ka manamana nui ma ka ʻōlelo Dutch, a ʻo ka ʻīniha ka lōʻihi o ka manamana nui. ʻOiaʻiʻo, ʻokoʻa nō hoʻi ka lōʻihi o ka manamana nui. I ke kenekulia 14, ua hoʻolaha ʻo King Edward II i ka "Standard Legal Inch". ʻO ke kānāwai, ʻo ka lōʻihi o nā hua nui ʻekolu i koho ʻia mai waenakonu o nā pepeiao bale a hoʻonohonoho ʻia i kahi lālani he hoʻokahi ʻīniha.
Ma keʻano laulā 1″=2.54cm=25.4mm
He aha ka DN
ʻO DN kahi ʻāpana kikoʻī i hoʻohana pinepine ʻia ma Kina a me nā ʻōnaehana ʻEulopa, a ʻo ia hoʻi ke kikoʻī no ka hōʻailona ʻana i nā paipu.nā kiwikā, nā flanges, nā mea hoʻopili, a me nā pamu, e like meDN250.
ʻO DN ke anawaena nominal o ka paipu (ʻike ʻia hoʻi ʻo ke anawaena nominal), e hoʻomaopopo: ʻaʻole kēia ke anawaena o waho a ʻaʻole hoʻi ke anawaena o loko, akā ʻo ka awelika o ke anawaena o waho a me ke anawaena o loko, i kapa ʻia ʻo ke anawaena o loko awelika.
He aha ka meaΦ
Φ he anakahi maʻamau, e pili ana i ke anawaena o waho o nā paipu, a i ʻole nā kuʻekuʻe lima, ke kila poepoe a me nā mea ʻē aʻe.
No laila he aha ka pilina ma waena o lākou?
ʻO ka mea mua, ʻaneʻane like nā manaʻo i hōʻailona ʻia e """ a me "DN". ʻO ke ʻano nui o lākou ke anawaena inoa, e hōʻike ana i ka nui o kēia kikoʻī, aΦ ʻo ia ka hui pū ʻana o nā mea ʻelua.
ʻo kahi laʻana
Eia kekahi laʻana, inā he DN600 ka paipu kila, inā ua hōʻailona ʻia ka paipu kila like ma nā ʻīniha, lilo ia i 24″. Aia kekahi pilina ma waena o nā mea ʻelua?
ʻAe ka pane! ʻO ka ʻīniha maʻamau he helu holoʻokoʻa a hoʻonui pololei ʻia e 25 e like me DN, e like me 1″*25=DN25, 2″*25=50, 4″*25=DN100, a pēlā aku. ʻOiaʻiʻo, aia nā mea like ʻole e like me 3″*25=75 ʻO ka hoʻopuni ʻana he DN80, a aia kekahi mau ʻīniha me nā semicolons a i ʻole nā kiko decimal e like me 1/2″, 3/4″, 1-1/4″, 1-1/2″, 2-1/2″, 3-1/ 2″ a pēlā aku, ʻaʻole hiki ke helu ʻia kēia mau mea e like me kēlā, akā ua like ka helu ʻana, ʻo ia hoʻi ka waiwai i kuhikuhi ʻia:
1/2″=DN15
3/4″=DN20
1-1/4″=DN32
1-1/2″=DN40
