AWWA tus qauv 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 tshaj 190 AWWA Standards. Los ntawm qhov chaw mus rau qhov chaw cia, los ntawm kev kho mob mus rau kev faib khoom, AWWA Standards npog cov khoom thiab cov txheej txheem cuam tshuam rau txhua qhov chaw ntawm kev kho dej thiab kev muab khoom. AWWA C504 yog ntawm tus neeg sawv cev, nws yog ib hom rubble rooj npauj npaim valve.
AWWA C504 npauj npaim valve muaj ob daim ntawv, midline kab mos foob thiab ob chav eccentric mos foob, feem ntau, tus nqi ntawm midline mos foob yuav pheej yig dua ob npaug eccentric, ntawm chav kawm, qhov no feem ntau ua raws li cov neeg siv khoom xav tau. Feem ntau qhov ua haujlwm siab rau AWWA C504 yog 125psi, 150psi, 250psi, flange kev twb kev txuas siab tus nqi yog CL125, CL150, CL250.
AWWA C504 npauj npaim valve feem ntau yog siv rau hauv cov dej kho dej, qhov nruab nrab yuav tsum yog dej tsis muaj impurities, cov yam ntxwv ntawm cov roj hmab foob ntxiv dag zog rau kev sib khi ntawm lub valve, kom lub valve tuaj yeem ua tiav 0 to. Hauv kev xaiv cov khoom siv lub cev valve, feem ntau yog cov hlau nplaum yog qhov tseem ceeb, ua raws li cov pa roj carbon steel kuj ua tau. Kev xaiv valve disc sealing nplhaib, EPDM, NBR, NR muaj, raws li cov neeg siv khoom xav tau los xaiv.
Piv nrog rau EN558-13,14 series npauj npaim li qub, AWWA C504 npauj npaim valve muaj lub cev tuab dua thiab cov kab tuab tuab dua, thiab tseem muaj qhov sib txawv me ntsis ntawm lwm qhov ntev, uas tuaj yeem pom hauv cov lus hauv qab no. Tau kawg, rau kev ua haujlwm, tsis muaj qhov sib txawv loj nrog rau lwm cov roj hmab-sealed npauj npaim li qub.
Dab tsi cov tuam ntxhab tuaj yeem ua AWWA C504 npauj npaim valve hauv Suav teb? Raws li kuv paub, tsis muaj ntau lub tuam txhab 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 tuam txhab lag luam uas tuaj yeem tsim AWWA C504 npauj npaim valve, Zhongfa Valve muaj nws tus kheej pwm thiab nws tus kheej ua rhiav, uas muaj peev xwm ua kom tiav cov khoom ntawm npauj npaim valve nrog zoo thiab kom muaj nuj nqis.
Cov nram qab no yog npauj npaim valve ntawm AWWA C504 tsim los ntawm Tianjin Zhongfa Valve, Yog tias koj xav paub ntau ntxiv txog AWWA C504 cov khoom, koj tuaj yeem tiv tauj peb.
