Tus qauv AWWA yog Lub Koom Haum American Water Works Association thawj zaug luam tawm cov ntaub ntawv pom zoo hauv xyoo 1908. Niaj hnub no, muaj ntau dua 190 AWWA Cov Qauv. Los ntawm qhov chaw mus rau qhov chaw khaws cia, los ntawm kev kho mus rau kev faib tawm, AWWA Cov Qauv npog cov khoom thiab cov txheej txheem ntsig txog txhua qhov chaw ntawm kev kho dej thiab kev muab dej. AWWA C504 yog tus sawv cev ib txwm muaj, nws yog ib hom lub rooj zaum pob zeb npauj npaim valve.
AWWA C504 npauj npaim valve muaj ob hom, midline kab mos foob thiab ob chav eccentric mos foob, feem ntau, tus nqi ntawm midline mos foob yuav pheej yig dua li ob chav eccentric, tau kawg, qhov no feem ntau ua raws li qhov xav tau ntawm cov neeg siv khoom. Feem ntau qhov ua haujlwm siab rau AWWA C504 yog 125psi, 150psi, 250psi, flange kev sib txuas siab tus nqi yog CL125, CL150, CL250.
AWWA C504 npauj npaim valve feem ntau yog siv rau hauv cov dej kho, cov khoom siv uas xav tau yog dej tsis muaj impurities, cov yam ntxwv ntawm cov roj hmab foob ua kom lub valve ua haujlwm sealing zoo, yog li ntawd lub valve tuaj yeem ua tiav 0 leakage. Hauv kev xaiv cov khoom siv lub cev valve, feem ntau yog hlau ductile yog qhov tseem ceeb, ua raws li cov hlau carbon kuj ua tau. Kev xaiv ntawm lub nplhaib kaw valve disc, EPDM, NBR, NR muaj, raws li cov neeg siv khoom xav tau los ua qhov kev xaiv.
Piv rau EN558-13,14 series npauj npaim li qub, AWWA C504 npauj npaim li qub muaj lub cev tuab dua thiab lub spindle tuab dua, thiab kuj muaj qhov sib txawv me ntsis hauv lwm qhov ntev, uas tuaj yeem pom hauv cov lus qhia hauv qab no. Tau kawg, rau kev ua haujlwm, tsis muaj qhov sib txawv loj nrog lwm cov roj hmab-kaw npauj npaim li qub.
Cov chaw tsim khoom twg tuaj yeem ua AWWA C504 npauj npaim valve hauv Suav teb? Raws li kuv paub, tsis muaj ntau lub chaw tsim khoom uas tuaj yeem ua AWWA C504 npauj npaim valve, ntau lub Hoobkas muaj kev paub ntau dua hauv kev tsim EN558-13 / 14 series npauj npaim valve, thiab tsis muaj kev paub ntau hauv kev tsim AWWA C504 npauj npaim valve, Tianjin Zhongfa Valve yog ib qho ntawm cov chaw tsim khoom uas tuaj yeem tsim AWWA C504 npauj npaim valve, Zhongfa Valve muaj nws tus kheej pwm thiab nws tus kheej lub chaw ua haujlwm, uas tuaj yeem ua tiav kev tsim cov npauj npaim valve nrog qhov zoo thiab ntau.
Cov hauv qab no yog lub npauj npaim valve ntawm AWWA C504 tsim los ntawm Tianjin Zhongfa Valve, Yog tias koj xav paub ntau ntxiv txog cov khoom AWWA C504, koj tuaj yeem tiv tauj peb.
