Igipimo cya AWWA ni Ishyirahamwe ry’amazi ry’Abanyamerika ryasohoye bwa mbere inyandiko zumvikanyweho mu 1908. Uyu munsi, hari amahame arenga 190 ya AWWA. Kuva aho biva kugeza kububiko, kuva kubuvuzi kugeza kubikwirakwizwa, Ibipimo bya AWWA bikubiyemo ibicuruzwa nibikorwa bijyanye nibice byose byo gutunganya amazi no gutanga. AWWA C504 niyisanzwe ihagarariwe, ni ubwoko bwimyanda yibinyugunyugu.
AWWA C504 valve yikinyugunyugu ifite uburyo bubiri, umurongo wo hagati woroshye kashe hamwe na kashe ya eccentric yoroheje, mubisanzwe, igiciro cyikimenyetso cyoroheje cyo hagati kizaba gihendutse kuruta icya kabiri, byanze bikunze, ibi bikorwa muburyo bukurikije ibisabwa nabakiriya. Mubisanzwe igitutu cyakazi kuri AWWA C504 ni 125psi, 150psi, 250psi, igipimo cyumuvuduko wa flange ni CL125, CL150, CL250.
AWWA C504 ikinyugunyugu ikoreshwa cyane cyane mumishinga yo gutunganya amazi, uburyo bukenewe ni amazi adafite umwanda, ibiranga kashe ya reberi bishimangira imikorere ya kashe ya valve, kugirango valve ibashe kugera kumeneka 0. Muguhitamo ibikoresho byumubiri wa valve, mubisanzwe ibyuma byangiza nibyo byingenzi, bigakurikirwa nicyuma cya karubone nabyo birashoboka. Guhitamo impeta ya valve ifunga impeta, EPDM, NBR, NR irahari, ukurikije ibyo umukiriya asabwa kugirango ahitemo.
Ugereranije na EN558-13,14 yuruhererekane rwibinyugunyugu, ikinyugunyugu cya AWWA C504 gifite umubiri wijimye hamwe na diameter nini cyane, kandi hariho itandukaniro rito mubindi bipimo, ushobora kubibona kumeza ikurikira. Birumvikana, kubikorwa, nta tandukaniro rinini hamwe nibindi binyugunyugu bifunze.
Ni izihe nganda zishobora gukora AWWA C504 ikinyugunyugu mu Bushinwa? Nkuko mbizi, ntababikora benshi bashobora gukora ikinyugunyugu cya AWWA C504, inganda nyinshi zifite uburambe mukubyaza umusaruro ibinyugunyugu bya EN558-13 / 14, kandi ntabwo bifite uburambe buke mukubyara AWWA C504 ikinyugunyugu, Tianjin Zhongfa Valve nimwe mubakora ibicuruzwa bishobora kubyara AWWA C504 ikinyugunyugu, Zhongfa Valve ifite ibumba ryayo hamwe n’amahugurwa yayo yo gutunganya, ashobora kurangiza umusaruro wa ikinyugunyugu gifite ubuziranenge n'ubwinshi.
Ibikurikira ni ikinyugunyugu cya AWWA C504 cyakozwe na Tianjin Zhongfa Valve, Niba ushaka kumenya byinshi kubyerekeye ibicuruzwa bya AWWA C504, ushobora no kutwandikira.
