Umwanya wa valve Φ, umurambararo DN, inchi” Ushobora gutandukanya ibi bipimo?

Akenshi hari inshuti zidasobanukiwe isano iri hagati y'ibisobanuro bya "DN", "Φ"na"". Uyu munsi, ndagusobanurira muri make isano iri hagati y'ibyo bitatu, nizeye kugufasha!

"Inches" ni iki?

Inch (“) ni igikoresho gikoreshwa cyane mu buryo bwo kugena imiterere y’ibikoresho muri Amerika, nk'imiyoboro y'icyuma,valve, imigozi, inkokora, ipompo, udupira tw'inyuma, n'ibindi, nk'uko ibisobanuro byabyo ari santimetero 10.

Inches (inches, mu magambo ahinnye nka in.) bivuze igikumwe mu Giholandi, naho inches ni uburebure bw'igikumwe. Birumvikana ko uburebure bw'igikumwe nabwo butandukanye. Mu kinyejana cya 14, Umwami Edward wa II yashyizeho "Inches Isanzwe yemewe". Ingingo ni uko uburebure bw'ibinyampeke bitatu binini byatoranijwe hagati mu mahundo ya sayiri kandi bitondetse mu murongo ari santimetero imwe.

Muri rusange 1″=2.54cm=25.4mm

DN ni iki?

DN ni igikoresho gikoreshwa cyane mu Bushinwa no mu Burayi, kandi ni nacyo gikoreshwa mu gushyira ikimenyetso ku miyoboro,valve, flanges, fittings, na pompe, nkaDN250.

DN yerekeza ku murambararo w’umuyoboro (uzwi kandi nka umurambararo w’umuyoboro), icyitonderwa: uyu si umurambararo w’inyuma cyangwa umurambararo w’imbere, ahubwo ni impuzandengo y’umurambararo w’inyuma n’umurambararo w’imbere, witwa umurambararo w’imbere mpuzandengo.

Ni ikiΦ

Φ ni igice gisanzwe, kivuga ku murambararo w'inyuma w'imiyoboro, cyangwa inkokora, icyuma kizingiye n'ibindi bikoresho.

None se ni iyihe sano iri hagati yabo?

Mbere na mbere, ibisobanuro byanditseho """ na "DN" hafi ya byose ni bimwe. Muri make bivuze umurambararo w'izina, bigaragaza ingano y'iyi ngingo, kandiΦ ni uruvange rw'ibyo byombi.

urugero

Urugero, niba umuyoboro w'icyuma ari DN600, niba umuyoboro w'icyuma umwe washyizweho ikimenyetso muri santimetero, uba santimetero 24. Ese hari isano iri hagati y'ibyo byombi?

Igisubizo ni yego! Isenti rusange ni umubare w'intege kandi ikubye inshuro 25 mu buryo butaziguye bingana na DN, nka 1″*25=DN25, 2″*25=50, 4″*25=DN100, nibindi. Birumvikana ko hari izindi zitandukanye nka 3″*25=75 Kuzunguruka ni DN80, kandi hari santimetero zimwe na zimwe zifite semicolon cyangwa amanota ya decimal nka 1/2″, 3/4″, 1-1/4″, 1-1/2″, 2-1/2″, 3-1/2″ nibindi, ibi ntibishobora kubarwa gutyo, ariko imibare ni imwe, muri rusange agaciro kagenwe:

1/2″ = DN15

3/4″ = DN20

1-1/4″ = DN32

1-1/2″ = DN40

2″ = DN50

2-1/2″ = DN65

3″ = DN80
