YINTONI YAMALUNGA?

Ngokubanzi, ububanzi bombhobho bunokwahlulwa bube yidayili ye-Outter (de), i-Innerter (D), ububanzi be-DN).
Apha ngezantsi ukukunika umahluko phakathi kwezi "DE, D, DN".

I-DN yiidayitha ezichanekileyo zombhobho

QAPHELA: Obuyiyo idayimitha engaphandle okanye ububanzi obungaphakathi; kufuneka inxulumene nophuhliso lokuqala lobunjineli be-piholilige kunye ne-impiriyali; ihlala isetyenziselwa ukuchaza umbhobho wentsimbi edityanisiweyo, ohambelana neeyunithi ze-Imperial ngolu hlobo lulandelayo:

Umbhobho wenxalenye 4: 4/8 intshi: DN15;
Umbhobho wemizuzu emi-6: I-6/8 intshi: DN20;
I-1 intshi yombhobho: I-1 intshi: DN25;
Intshi yombhobho emibini: 1 kunye ne-1/4 inches: DN32;
Isiqingatha se-intshi kumbhobho: 1 kunye ne-1/1 i-intshi: I-DN40;
Imibhobho emibini ye-intshi: i-intshi ezi-2: I-DN50;
I-intshi ezintathu ze-intshi: i-intshi ezi-3: I-DN80 (Iindawo ezininzi zibhalwe njenge-DN75);
Imibhobho ye-intshi ezine: I-Intshi ezi-4: DN100;
Amanzi, umbhobho wensimbi yensimbi (umbhobho wentsimbiokanye umbhobho wentsimbi engeyiyo i-pipe), umbhobho wentsimbi yentsimbi, umbhobho wensimbi ye-Polyvinyl Hyride (PVC) kunye neminye imibhobho ye-PVC kunye nezinye izinto ze-PVC, kufuneka zimakishwe nge-DN15, DN20, DN20, DN20).

 

I-De ubukhulu becala ibhekisa kububanzi bangaphandle bombhobho
Ukusetyenziswa ngokutsha kwelebheli, kufuneka ifakwe ilebheli ibe yindlela yobubanzi be-GARTER X;

Ikakhulu isetyenziselwa ukuchaza:umbhobho wentsimbi engenamthungo, I-PVC kunye neminye imibhobho yeplastiki, kunye neminye imibhobho efuna ubuncwane obucacileyo bodonga.
Thatha imibhobho yentsimbi ye-weldimed ye-welden njengomzekelo, nge-DN, iilebheli ezimbini zeelebheli zezi zilandelayo:
I-DN20 DE25 × 2.5mm
I-DN25 de32 × 3mm
I-DN32 de40 × 4mm
I-DN40 DE50 de50 × 4mm

......

 

D ngokubanzi ibhekisa kububanzi obungaphakathi bombhobho, d ibonisa ububanzi bangaphakathi bombhobho wekhonkrithi, kwaye φ ibonisa ububanzi besangqa esiqhelekileyo

Inokubonisa ubungakanani bodwa wombhobho, kodwa emva koko kufuneka iphinde iphindwe ngobukhulu bomhlaba.
Umzekelo, ¶225 × 3 kuthetha umbhobho onomgangatho ongaphandle we-25mm kunye nodonga lodonga lwe-3mm.
Umbhobho wentsimbi engenamthungo okanye umbhobho wensimbi engafanelekanga, kufuneka umakishwe "ububanzi be-Oute Ball
Umzekelo: φ107 × 4, apho i-φ inokushiywa.
I-China, i-ISO kunye neJapan yelebhile yentsimbi yentsimbi isebenzisa ubukhulu bobubanzi bokubonisa ubukhulu boluhlu lwe-pie yentsimbi. Ngolu hlobo lombhobho wentsimbi, indlela yokubonisa umbhobho wangaphandle wobubanzi × yodonga. Umzekelo: φ60.5 × 3.8

DE, DN, D, ф kuluhlu lwentetho!
De-- i-PPR, ipayipi, i-polyproplene ye-od
I-DN-Polythylene (PVC) ye-PVC, i-Iron yentsimbi, umbhobho wePlasitini yentsimbi yensimbi, i-Galvanimed yentsimbi yentsimbi
D - Ikhonkrithi ye-pingrete yombhobho
ф - i-seam yentsimbi yentsimbi yentsimbi
