Kodi mainchesi a nomweni?

Nthawi zambiri, m'mimba mwake imagawika m'mimba mwakunja (de), m'mimba mwake (d), mainloni mwadzina (DN).
Pansipa kuti akupatseni kusiyana pakati pa "de, d, DN".

DN ndi mainchesi mwadzidzidzi

Dziwani: Ino si dzanja lamanja kapena mulifupi mwake; ziyenera kukhala zokhudzana ndi kukula koyambirira kwa ma piperine apakati ndi magawo; Nthawi zambiri amagwiritsidwa ntchito pofotokoza chitoliro chachitsulo, chomwe chimafanana ndi zigawo zachifumu motere:

Mapaipi anayi: 4/8 inchi: DN15;
Chitoliro cha mphindi 6: 6/8 inchi: DN20;
1 inchi pipe: 1 inchi: DN25;
Inch pipe awiri: 1 ndi 1/4 mainchesi: DN32;
Chitoliro cha inchi: 1 ndi 1/2 mainchesi: DN40;
Chitoliro chachiwiri cha inchi: mainchesi 2: DN50;
Chitoliro zitatu-inchi: 3 mainchesi: DN80 (malo ambiri amalembedwanso monga DN75);
Chitoliro cha inchi anayi: mainchesi 4: DN100;
Madzi, kutumiza kwa mpweya wachitsulo (chitoliro chachitsuloKapenanso wosakhala wachitsulo wachitsulo), chitoliro chachitsulo cha chitsulo, chitoliro cha pulasitiki ndi polyvinyl (pvc) chitoliro ndi zida zina zam'maso, ziyenera kulembedwa ndi dambo lina la Nomu "(monga DN10).

 

Amatanthauza makamaka m'mimba yakunja ya chitoliro
Kugwiritsa ntchito kwa Dele kulemba, kumafunika kulembedwa kukhala mawonekedwe a mainchesi kunja kwa x makulidwe;

Makamaka kugwiritsidwa ntchito pofotokoza:chitoliro chachitsulo chosawoneka, PVC ndi mapaipi ena apulasitiki, ndi mapaipi ena omwe amafunikira khoma lomveka bwino.
Tengani chithunzithunzi chachitsulo chachitsulo mwachitsanzo, ndi DN, njira ziwiri zolembera izi:
DN20 de25 × 2.5mm
DN25 de32 × 3mm
DN32 de40 × 4mm
DN40 de50 × 4mm

......

 

D Nthawi zambiri amatanthauza mkati mwapakatu, D imawonetsa mkati mwa chitoliro cha konkriti, ndipo φ akuwonetsa m'mimba mwake

Φ imathanso kuwonetsa m'mimba mwapakati, koma kenako iyenera kukuchulukitsidwa ndi khoma makulidwe.
Mwachitsanzo, φ25 × 3 amatanthauza chitoliro chokhala ndi zaka 25m ndi khoma la 3mm.
Chitoliro chachitsulo chosawoneka kapena chitoliro chopanda chitsulo, chikuyenera kulembedwa kuti "m'mimba mwake × makulidwe".
Mwachitsanzo: φ107 × 4, pomwe φ itha kuzolowera.
China, Iso ndi Chigawo cha Japan cha ziphuphu zachitsulo zogwirizira zokutira za khoma kuti zisonyeze khoma la khoma lachitsulo. Kwa chitoliro chamitundu ino, njira yofotokozera chitoliro chakunja kwa mainzera × pakhoma. Mwachitsanzo: φ60.5 × 3.8

De, DN, D, ф ya mawu osiyanasiyana!
De-- PPR, PE PER, Polypropylene Pipe
DN - polyethylene (PVC) chitoliro, choponyera chitoliro chachitsulo, chitoliro cha pulasitiki, chitoliro chachitsulo chojambulachi mwatsopano
D - CENRRETE PIP SIYAMILES
ф - Chithunzithunzi chachitsulo chosoka
