Hariho inshuti zitumva isano iri hagati yihariye ya "DN", "Φ"NA" "" ". Uyu munsi, nzavuga muri make umubano hagati ya batatu kuri wewe, twizeye kuzagufasha!
Inch "
Inch (") nigice gikunze gukoreshwa muri gahunda y'Abanyamerika, nk'ibyuma by'ibyuma,indangagaciro, flanges, inkokora, pompe, tees, nibindi, nkibisobanuro ni 10 ".
Inch (santimetero, amagambo ahinnye nko muri.) Bisobanura igikumwe mu Buhoto, kandi santimetero ni uburebure bw'intoki. Birumvikana ko uburebure bw'urutoki nabwo butandukanye. Mu kinyejana cya 14, Umwami Edward wa II yangije "ibisanzwe byemewe n'amategeko". Guhitamo ni uko uburebure bwibinyampeke bitatu binini byatoranijwe hagati yamatwi ya sayiri kandi bitunganijwe kumurongo ni santimetero imwe.
Mubisanzwe 1 "= 2.54cm = 25.4mm
DN ni iki
DN nishami rikoreshwa rikoreshwa mubushinwa na sisitemu yuburayi, kandi ni kandi ibisobanuro byo kuranga imiyoboro,indangagaciro, flanges, fittings, na pompe, nkaDn250.
DN bivuga diameter yizina ryumuyoboro (uzwi kandi nka diameter yizina), Icyitonderwa: Ibi ntabwo ari diameter yo hanze cyangwa diameter yimbere, yitwa impuzandengo yimbere, yitwa impuzandengo yimbere.
NikiΦ
Φ ni igice rusange, bivuga diameter yo hanze yumuyoboro, cyangwa inkokora, kuzunguruka nibindi bikoresho.
None se isano iri hagati yabo?
Mbere ya byose, ibisobanuro byaranzwe na "" "na" na "na" na "na" na gato bisobanura diameter yizina, byerekana ubunini bw'iki kimenyetso, kandiΦ ni ihuriro rya bibiri.
Kurugero
Kurugero, niba umuyoboro w'icyuma uri dn600, niba umuyoboro umwe wa steel waranzwe muri santimetero, biba 24 ". Hoba hariho isano iri hagati ya yombi?
Igisubizo ni yego! Inkongora rusange ni integer kandi ihuye na 25 ihwanye na DN, nka 1 "* 25 = 1", 35 ", 1/4", 1-1 / 2 ", 2-1 / 2 ", 3-1 / 2" Kandi rero, ibyo ntibishobora kubarwa nkibi, ariko kubara biri hafi, ahanini agaciro kerekanwe:
1/2 "= DN15
3/4 "= DN20
1-1 / 4 "= Dn32
1-1 / 2 "= DN40
2 "= DN50
2-1 / 2 "= DN65
3 "= DN80
