Ni ubuhe busobanuro bw'amanota 2, 4 na 6 mu bikoresho bya pipe ya valve? Oxygene ya valve, umuyoboro wa valve, valve gutwika impamvu zisesengura
Nigute ushobora gutandukanya ingano ya valve? Ni "iminota," "inches," cyangwa "DN…"? Waba uzi icyo bivuze?
Mbere ya byose, reka tumenye inkomoko ya "inch":
santimetero (incimetero, mu magambo ahinnye nko muri.), mu giholandi, igisobanuro cy'umwimerere ni igikumwe, santimetero ni uburebure bw'igikumwe, byanze bikunze, uburebure bw'igikumwe nabwo buratandukanye.
Izuba ntirirasa. Ingoma y'Ubwongereza yari ikomeye. Igihugu cyari gikomeye kandi gifite ijwi. Mu kinyejana cya 14, Umwami Edward II yatangaje “intambwe isanzwe yemewe”. Ukurikije iryo tegeko, uburebure bwingano nini nini nini zikurikiranye ni santimetero imwe (hafi mm 25.4).
Tugeze aho, mubisanzwe tujya mububiko bwibyuma kugura valve cyangwa umuyoboro, gufatanya, nibindi, ntitwumva gufata inshuti gufata ingero zo kugura muburyo butaziguye, uca imanza ibisobanuro rusange byibisobanuro, muminota mike cyangwa santimetero nke , mubyukuri reba amazi ya valve hamwe numuyoboro uhuriweho cyangwa ushizwe kumurongo wapakiwe, nka 1/2 ', 3/4', 1 ', DN15 nibindi.
Nkuko bigaragara hano: Amazi ashyushye nubukonje iburyo-inguni ya valve yo koza umusarani, ubunini DN15.
Nshuti nshuti, niba ushaka kumva no kwiga ibisobanuro nubunini bwiyi mibande, ni ngombwa kuzirikana umubano uhuriweho ukurikira:
Guhindura formulaire yibanze: santimetero 1 ≈25.4 mm = amanota 8 (amanota kuri make)
Noneho: santimetero 1 = 1/8 '(muri) ≈3.175mm
2 cm = 1/4 '(intambwe)
4 cm = 1/2 '(intambwe)
6 cm = 3/4 '(muri)
(Mu ntumbero yo gufata mu mutwe, uduce duke twa santimetero twikuba 8 kugirango tubone amanota.)
Igishushanyo gikurikira cyerekana isano iri hagati y "iminota" na "santimetero":
Mubuzima, valve ikoreshwa cyane ni 1/2 '(4 valve), rimwe na rimwe ikitwa DN15, mubyukuri, ibisobanuro birasa, ariko uburyo bwo kuranga buratandukanye.
Ubusanzwe rero twita amanota 4 n'amanota 6 na 1 santimetero y'amazi cyangwa umuyoboro w'amazi, amanota 4, amanota 6, santimetero 1 bivuga valve y'amazi cyangwa umuyoboro w'amazi wa diameter ya sisitemu y'Ubwongereza, izina ryuzuye ni Abongereza.
Nkuko bigaragara hano hepfo: 1/2 santimetero ni 4 point valve (DN15) diameter nominal ya 15, diameter yumurongo wa 19mm.
Igice: mm
Ubudodo buhuye bwerekanwa nkibi bikurikira:
Rimwe na rimwe, nubwo umubiri wa valve utaranzwe nibisobanuro, turashobora gukoresha umutegetsi gupima hafi ibisobanuro bya valve, mubisanzwe 4 valve kumutwe wimbere mubisanzwe diameter ya 18 ~ 20mm, niba urudodo rwo hanze rushobora gupimwa diameter , kimwe.
Ishusho ikurikira irerekana robine yimashini imesa ikoreshwa mumiryango:
Igishushanyo gikurikira ni 3/4 ', kizwi kandi nka 6 valve (DN20), diameter nominal ya 20, mubisanzwe hafi 24mm imbere ya diameter.
Igice: mm
Igishushanyo gikurikira cyerekana uburyo bwo gupima uburyo bwo kugereranya hafi ya point ya 4 na 6:
Duhereye kubyavuzwe haruguru, abafatanyabikorwa benshi bato bazitiranya, ibisobanuro bya valve DN bisobanura icyo, mubyukuri, DN ya valve ya DN20 ni ikimenyetso cya diameter nominal, diameter nominal (nanone izwi nka mean outs>
DN rero ntabwo ari diameter yo hanze cyangwa diameter y'imbere, ariko yegereye diameter y'imbere. Icyiciro gito cyumuvuduko, uburebure bwurukuta ruto, DN munsi ya diameter y'imbere; Kubyiciro byumuvuduko mwinshi, uburebure bwurukuta ni bunini, kandi DN iruta diameter y'imbere. DN ** Diameter ya nominal, iri muri milimetero, ariko diameter nominal nubunini bwizina, ntabwo ingano yukuri ya.
Kurugero, uwashizeho umuyoboro cyangwa valve abara ko hasabwa umuyoboro ufite diameter y'imbere ya 102mm n'ubugari bw'urukuta rwa 3mm, naho diameter yo hanze y'umuyoboro ni 108mm. Ukurikije igishushanyo mbonera cyicyuma, hariho umuyoboro nkuyu. Muri iki gihe, umuyoboro ufite diameter y'imbere ya 102mm ugomba gushyirwa mubice nka diameter nominal ya hafi, ni ukuvuga igishushanyo mbonera ni DN100. Biragaragara ko ingano yizina igiye kuba nto kurenza diameter y'imbere. Mu rundi rubanza, umuyoboro ufite diameter yo hanze ya 108mm uracyakoreshwa. Bitewe numuvuduko mwinshi, uburebure bwurukuta burasabwa kuba 6mm, bityo diameter yimbere yumuyoboro ni 96. Muri iki gihe, valve yakoreshejwe iracyari DN100, kandi ingano yizina iruta diameter y'imbere y'umuyoboro ufunze .
Igishushanyo gikurikira ni 1 '(muri) DN25 ya valve, mubisanzwe ntabwo yitwa 8 valve, diameter nominal ni 25, diameter yumurongo ni 30mm, nibindi:
Igishushanyo gikurikira kirerekana 1,2 '(muri.) DN32 valve ifite diameter nominal ya 32 hamwe na diameter y'imbere ya 39mm.
Igishushanyo gikurikira cyerekana 1.5 '(muri.) DN40 valve, diameter nominal ni 40, diameter yimpapuro ni 46mm
Hasi ni 2 '(muri.) DN50 valve ifite diameter nominal ya 50 na diametre yimbere imbere ya 56mm
Igishushanyo gikurikira cyerekana isano ijyanye na santimetero ya pipe nubunini bwizina:
Binyuze mu isesengura rirambuye ryavuzwe haruguru, ubushakashatsi bwimbitse, abafatanyabikorwa bato bagomba gusobanukirwa nubuzima rusange bwamazi yubuzima, "ingingo" na "santimetero" kubisobanuro byayo.
