Umuyoboro wa diameter De, DN, d ф Ibisobanuro
De 、 DN 、 d 、 ф Icyerekezo cyerekana icyerekezo cya
De - diameter yo hanze ya PPR, umuyoboro wa PE hamwe na polypropilene
DN - Diameter ya nomero yumuyoboro wa polyethylene (PVC), umuyoboro wicyuma, umuyoboro wa pulasitiki wibyuma hamwe numuyoboro wicyuma
D - diameter nominal yumuyoboro wa beto
ф-- Diameter nominal yumuyoboro wicyuma idafite icyerekezo ni ф 100: 108 X 4
Itandukaniro hagati ya diameter diameter DE na DN
1. Umubano uhuye nibice byicyongereza nuburyo bukurikira:
4/8: DN15;
6/8 santimetero: DN20;
Umuyoboro wa santimetero 1: 1 cm: DN25;
Umuyoboro wa santimetero ebyiri: 1 na 1/4 cm: DN32;
Inch igice cya kabiri: 1 na 1/2 cm: DN40;
Umuyoboro wa santimetero ebyiri: santimetero 2: DN50;
Umuyoboro wa santimetero eshatu: 3 cm: DN80 (nayo yashyizweho ikimenyetso nka DN75 ahantu henshi);
Umuyoboro wa santimetero enye: 4 cm: DN100;
2.
Ikoreshwa cyane mugusobanura: imiyoboro yicyuma idafite icyerekezo, PVC nindi miyoboro ya pulasitike, nindi miyoboro isaba uburebure bwurukuta.
Gufata umuyoboro w'icyuma usudira nk'urugero, uburyo bwa DN na De uburyo bukurikira:
DN20 De25X2.5mm
DN25 De32X3mm
DN32 De40X4mm
DN40 De50X4mm
Tumenyereye gukoresha DN kugirango dushyireho imiyoboro y'ibyuma yasuditswe, kandi ni gake dukoresha De kugirango dushyireho imiyoboro itabigizemo uruhare;
Ariko gushyira imiyoboro ya pulasitike ni ikindi kibazo; Bifitanye isano kandi ningeso zinganda. Mubikorwa nyabyo byo kubaka, 20, 25, 32 nindi miyoboro twita gusa yerekeza kuri De, ntabwo DN.
Ukurikije uburambe bufatika kurubuga:
a. Uburyo bwo guhuza ibikoresho bibiri byumuyoboro ntakindi kirenze guhuza imigozi ya screw na flange ihuza.
b. Umuyoboro wibyuma hamwe numuyoboro wa PPR urashobora guhuzwa nuburyo bubiri bwavuzwe haruguru, ariko umugozi wumugozi uroroha cyane kumiyoboro iri munsi ya 50, kandi flange yizewe kumiyoboro irenze 50.
c. Niba imiyoboro ibiri yicyuma ikozwe mubikoresho bitandukanye ihujwe, niba reaction ya selile ya galvanic izasuzumwa, bitabaye ibyo igipimo cyo kwangirika kwimiyoboro ikora cyihuta. Nibyiza gukoresha flanges kugirango uhuze, kandi ukoreshe ibikoresho byo kubika reberi kugirango utandukanye ibyuma byombi, harimo na bolts, hamwe na gasketi kugirango wirinde guhura.
Itandukaniro hagati ya DN, De na Dg
DN Diameter
De diameter yo hanze
Dg diameter gong. Dg diameter gong ikorerwa mubushinwa, hamwe nibiranga Ubushinwa, ariko ntibikoreshwa
a. Uburyo butandukanye bwo gushiraho imiyoboro itandukanye:
1. Kubijyanye no gukwirakwiza gazi y'amazi imiyoboro y'ibyuma (galvanised cyangwa idafite galvanised), imiyoboro y'ibyuma hamwe n'indi miyoboro, diameter y'umuyoboro igomba kwerekanwa na diameter nominal DN (nka DN15, DN50);
2. ;
3. Kubijyanye na beto ishimangiwe (cyangwa beto), imiyoboro yibumba, imiyoboro ya ceramic irwanya aside, imiyoboro ya liner nindi miyoboro, diameter ya pipe igomba kugaragazwa na diameter y'imbere d (nka d230, d380, nibindi);
4. Ku miyoboro ya pulasitike, diameter ya pipe igomba kugaragazwa hakurikijwe ibicuruzwa;
5. Iyo diameter nominal DN ikoreshwa mugushushanya diameter ya pipe mugushushanya, hagomba kubaho imbonerahamwe yo kugereranya hagati ya diameter nominal DN nibisobanuro bijyanye nibicuruzwa.
b. Isano ya DN, De na Dg:
De ni diameter yurukuta rwinyuma rwumuyoboro
DN ni De gukuramo igice cyubugari bwurukuta rwumuyoboro
Dg muri rusange ntabwo ikoreshwa
1 Umuyoboro wa diameter ugomba kuba muri mm.
2 Imvugo ya diameter ya pipe igomba kubahiriza ingingo zikurikira:
1 Kubyuma byogukwirakwiza amazi ya gaz (galvanised cyangwa non galvanised), imiyoboro yicyuma nindi miyoboro, diameter yumuyoboro igomba kwerekanwa na diameter nominal DN;
2 Umuyoboro w'icyuma udafite ikidodo, umuyoboro w'icyuma usudira (icyuma kigororotse cyangwa icyuma kizunguruka), umuyoboro w'umuringa, umuyoboro w'icyuma udafite ingese hamwe n'indi miyoboro, diameter y'umuyoboro igomba kuba diameter yo hanze × Uburebure bw'urukuta;
3 Ku miyoboro ya beto ishimangiwe (cyangwa beto), imiyoboro y'ibumba, imiyoboro ya ceramic irwanya aside, imiyoboro ya liner nindi miyoboro, diameter ya pipe igomba kugaragazwa na diameter y'imbere d;
4 Ku miyoboro ya pulasitike, diameter ya pipe igomba kugaragazwa hakurikijwe ibicuruzwa;
5 Iyo diameter nominal DN ikoreshwa mugushushanya diameter ya pipe mugushushanya, imbonerahamwe yo kugereranya hagati ya diameter nominal DN nibisobanuro bijyanye nibicuruzwa bizatangwa.
Imiyoboro idahwitse ya polyvinyl chloride yo kubaka amazi - de (nomero yo hanze ya nominal) kugirango isobanurwe × E (uburebure bw'urukuta rw'izina) bisobanura (GB 5836.1-92).
Imiyoboro ya polypropilene (PP) yo gutanga amazi × E igereranya (diameter nominal yinyuma × Uburebure bwurukuta)
Kumenyekanisha imiyoboro ya pulasitike ku bishushanyo mbonera
Ingano yubunini
Uhagarariwe na DN
Bikunze kwitwa "ubunini bw'izina", ntabwo ari diameter yo hanze y'umuyoboro cyangwa diameter y'imbere y'umuyoboro. Nimpuzandengo ya diameter yo hanze na diameter y'imbere, ibyo bita impuzandengo imbere ya diameter.
Kurugero, ikimenyetso cya metero (ubunini bwa mm) ubunini bwa plastike ifite diameter yo hanze ya 63mm DN50
Ingano ya ISO
Fata Da nka diameter yinyuma yumuyoboro wa PVC numuyoboro wa ABS
Fata De nka diameter yinyuma yumuyoboro wa PP numuyoboro wa PE
Kurugero, ikimenyetso cyerekana imiyoboro ya pulasitike ifite diameter yo hanze ya 63mm (ubunini bwa mm)
