Valve bophara Φ, bophara DN, intshi” Na o ka khetholla diyuniti tsena ga tlhaloso?

Gantši go na le bagwera bao ba sa kwešišego kamano magareng ga ditlhalošo tša “DN”, “ .Φ" le """. Lehono, ke tla le akaretša tswalano magareng ga tše tharo tše, ke holofela go le thuša!

Inch (“) ke yuniti ya ditlhaloso yeo e dirišwago ka tlwaelo tshepedišong ya Amerika, e bjalo ka diphaephe tša tšhipi, .di-valve di-valve, flanges, elbows, dipompo, tee, joalo-joalo, tse kang ga tlhaloso ke 10 ′′.

Intshi (intshi, e khutsofaditšwe bjalo ka in.) e bolela monwana o mogolo ka Sedutch, gomme intšhi ke botelele bja monwana o mogolo. Ke therešo gore botelele bja monwana o mogolo le bjona bo fapane. Lekgolong la bo-14 la nywaga, Kgoši Edward II o ile a tsebatša “Standard Legal Inch”. Taelo ke gore botelele bja mabele a mararo a magolo ao a kgethilwego go tšwa bogareng bja ditsebe tša garase gomme a beakantšwe ka mothaladi ke intšhi e tee.

Ka kakaretšo 1 ′′ = 2.54cm = 25.4mm

DN ke eng

DN ke yuniti ya gateletšo yeo e šomišwago ka tlwaelo kua China le ditshepedišo tša Yuropa, gomme gape ke gateletšo ya go swaya diphaephe, .di-valve di-valve, di- flange, didirišwa le dipompo, tše bjalo kaDN250 ya go swana le.

DN e bua ka bophara ba lebitso la phaephe (hape tsejoang e le bophara ba lebitso), hlokomela: ena ha se bophara ba ka ntle kapa bophara ba ka hare, empa karolelano ea bophara ba ka ntle le bophara ba ka hare, e bitsoang bophara ba ka hare karolelano.

Ke engΦ

Φ ke yuniti e tlwaelegilego, yeo e bolelago ka bophara bja ka ntle bja diphaephe, goba di-elbow, tšhipi ya nkgokolo le didirišwa tše dingwe.

Bjale kgokagano magareng ga bona ke efe?

Pele ga tšohle, ditlhalošo tšeo di swailwego ka “”" le “DN” di nyakile di swana. Ge e le gabotse di bolela bophara bja leina, bjo bo bontšhago bogolo bja gateletšo ye, leΦ ke kopanyo ya tše pedi.

Mohlala

Ka mohlala, ge e ba phaephe ya tšhipi e le DN600, ge e ba phaephe ya tšhipi e swanago e swailwe ka disenthimithara, e ba 24′′. Na go na le kgokagano le ge e le efe magareng ga tše pedi tše?

Karabo ke ee! Intshi ya kakaretšo ke palomoka gomme e atišitšwe ka go lebanya ka 25 e lekana le DN, go swana le 1 ′′ * 25 = DN25, 2 ′′ * 25 = 50, 4 ′′ * 25 = DN100, bj.bj bjalo ka 1/2 ′′, 3/4 ′′, 1-1/4 ′′, 1-1/2 ′′, 2-1/2 ′′, 3-1/ 2 ′′ bjalobjalo, tše di ka se balwe ka tsela yeo, eupša go balwa go a swana ka go se nene, motheong ke boleng bjo bo laeditšwego:

1/2 ′′ = DN15

3/4 ′′ = DN20

1-1 / 4 ′′ = DN32

1-1 / 2 ′′ = DN40

2′′=DN50

2-1 / 2 ′′ = DN65

3′′=DN80
