Ubungakanani begama kunye neevalve zoxinzelelo oluncinci zihlelwa ngokwemigaqo yesakhiwo

Ubungakanani obuqhelekileyo be-DN yimilinganiselo yamanani yazo zonke izincedisi zemibhobho kwinkqubo yemibhobho ukwahlula loo malungu aboniswe ngomsonto okanye idiameter yangaphandle. Idayamitha yegama linani elingqukuva elisetyenziswa njengesalathiso kwaye alifani nobungakanani bomatshini. I-PN luphawu lwamanani olunxulumene noxinzelelo. Linani elijikelezileyo elilungele ireferensi. Zonke izixhobo zombhobho ezinomlinganiselo ofanayo we-DN obonakaliswe ngoxinzelelo olufanayo lwegama P kunye nexabiso liya kuba nobukhulu bokudibanisa obufanayo obuhambelana nohlobo loqhagamshelwano lwesiphelo.
Idayamitha yegama
Ubungakanani obuqhelekileyo be-DN lidimensioni yamanani yazo zonke izincedisi zemibhobho kwinkqubo yemibhobho ukwahlula ezo ndawo zibonakaliswe ngomsonto okanye idiameter yangaphandle. Idayamitha yegama linani elingqukuva elisetyenziswa njengesalathiso kwaye alifani nobungakanani bomatshini.
Ubungakanani obuqhelekileyo buphawulwe ngonobumba "DN" lulandelwa luphawu lwamanani. Ukuba i-diameter ye-nominal yi-250mm, kufuneka ibhalwe njenge-DN250. Ubungakanani obuqhelekileyo beevalvu buchazwe kwiThebhile 1-44.
Itheyibhile 1-44 iValve ngobungakanani obuqhelekileyo uluhlu (GB/T1047-1995) (mm)
Qaphela: amagama angqindilili kwitheyibhile asetyenziswa ngokuqhelekileyo ubungakanani begama.
Uxinzelelo lwegama
I-PN luphawu lwamanani olunxulumene noxinzelelo. Linani elijikelezileyo elilungele ireferensi. Zonke izixhobo zombhobho ezinomlinganiselo ofanayo we-DN obonakaliswe ngoxinzelelo olufanayo lwegama P kunye nexabiso liya kuba nobukhulu bokudibanisa obufanayo obuhambelana nohlobo loqhagamshelwano lwesiphelo.
E-China, xa uxinzelelo oluncinci lubandakanyekayo, ngenxa yokucaca, iyunithi yokulinganisa idla ngokunikezelwa njenge "MPa".
EBritani, eUnited States nakwamanye amazwe, nangona ingqikelelo yoxinzelelo lwegama ibandakanyiwe kwimigangatho efanelekileyo, kodwa eyona ndlela yokusetyenziswa kwenkqubo yaseBritane iseyiyo >
Kukho inkqubo yebakala "K" kwimigangatho yaseJapan, efana ne-10K, i-20K, i-40K, njl njl. Ingqikelelo yenqanaba loxinzelelo iyafana nenkqubo yenqanaba loxinzelelo kwinkqubo yaseBrithani, kodwa iyunithi yokulinganisa i-metric. Ubudlelwane phakathi kwe "K" kwinqanaba kunye nenqanaba loxinzelelo liboniswa kwiThebhile 1-46.
Uluhlu loxinzelelo oluncinci lweevalvu luboniswe kwiThebhile 1-47

Iivalvu zahlulwe zaba ivelufa yesango, ivalve yebhabhathane, ivalve ejikelezayo, ivalve yeglowubhu, ivalve yokukhangela, ivalve yokhuseleko, ivalve yokunciphisa uxinzelelo, i-steam trap, ivalve yediaphragm, ivalve yeenjongo ezininzi njalo njalo. Iivalvu zesango zinokohlulwa zibe ziivalve zesango elinomphetho, iivalve zesango lentonga, iivalve zesango elijikelezayo, iivalvu zesango ezivula ngokukhawuleza kunye nokuvala, iivalve zesango ezishwabeneyo kunye nezinye iivalvu, bona itheyibhile engezantsi ngeenkcukacha.
