Valve molagare Φ, molagare DN, intšhe” A o ka farologanya diyuniti tseno tsa tlhaloso?

Gantsi go na le ditsala tse di sa tlhaloganyeng kamano fa gare ga ditlhaloso tsa “DN”, “ .Φ" le """. Gompieno, ke tla go sobokanya kamano magareng ga boraro jo, ke solofela go go thusa!

intšhe ke eng”

Inch (“) ke yuniti e e dirisiwang thata ya go tlhalosa dilo mo tsamaisong ya Amerika, e e jaaka dipeipi tsa tshipi, .dibelofo, flanges, dikgopo, dipompo, tees, joalo-joalo, tse kang ga tlhaloso ke 10 ′′.

Intšhe (intšhe, e khutshwafaditswe jaaka in.) e kaya monwana wa kgonope ka Sedatšhe, mme intšhe ke boleele jwa monwana wa kgonope. Gone ke boammaaruri gore boleele jwa monwana wa kgonope le jone bo farologane. Mo lekgolong la bo14 la dingwaga, Kgosi Edward II o ne a itsise “Intšhe e e Tlwaelegileng ya Semolao”. Taelo ke gore boleele jwa dithoro tse tharo tse dikgolo tse di tlhophilweng go tswa mo gare ga ditsebe tsa harese mme di rulagantswe ka mola ke intšhe e le nngwe.

DN ke eng

DN ke tlwaelehileng sebediswa ga tlhaloso yuniti China le European tsamaiso, 'me hape ke ga tlhaloso bakeng sa ho tshwaya dipeipi,dibelofo, di- flange, di- fitting le dipompo, tse di jaaka .DN250.

DN e bua ka molagare wa peipi (o o itsegeng gape jaaka molagare wa leina), ela tlhoko: seno ga se molagare wa kwa ntle kgotsa molagare wa ka fa gare, mme ke palogare ya molagare wa kwa ntle le molagare wa ka fa gare, o o bidiwang palogare ya molagare wa ka fa gare.

Ke engΦ

Φ ke yuniti e tlwaelehileng, e bolelang ka ntle bophara ba dipeipi, kapa dikhuno, potoloha tšepe le thepa e meng.

Ka jalo kgolagano ke eng fa gare ga tsone?

Sa ntlha, bokao jo bo tshwailweng ka “”" le “DN” bo batla bo tshwana. Tota bo kaya molagare o o tlwaelegileng, o o supang bogolo jwa tlhaloso eno, mme .Φ ke kopano ya bobedi jono.

Sekai

Sekao, fa peipi ya tshipi e le DN600, fa peipi e e tshwanang ya tshipi e tshwailwe ka disentimetara, e nna 24 ′′. A go na le kgolagano epe fa gare ga dilo tseno tse pedi?

Karabo ke ee! Intšhe ka kakaretso ke palo e e feletseng mme fa e atisiwa ka tlhamalalo ka 25 e lekana le DN, jaaka 1 ′′ * 25 = DN25, 2 ′′ * 25 = 50, 4 ′′ * 25 = DN100, jj. dintlha tse kang 1/2 ′′, 3/4 ′′, 1-1/4 ′′, 1-1/2 ′′, 2-1/2 ′′, 3-1 / 2 ′′ jj, tsena di ke ke tsa balwa jwalo, empa palo e batla e tshwana, hantlentle boleng bo boletsweng:
