Proco iyenera kukumbukira zovuta zina za polojekitiyi. Chodetsa nkhawa ndichakuti chotchingira ndi valavu yoyendera duckbill zitha kuonongeka ndi sitimayo ikadutsa. Kuti athetse vutoli, Proco iyenera kudziwa kutalika koyenera kwa diffuser. Mu pulojekitiyi, kutalika kwa diffuser ndi pafupifupi 741.5 mapazi kumapeto kwenikweni kwa chubu chotsutsa kugwa cha 1.5-mile.
Kale, mainjiniya ndi makontrakitala nthawi zambiri ankafunikira kulumikiza mabowo amtundu wina kuti azigwira ntchito pang'onopang'ono komanso otseguka kuti azitha kuyenda kwambiri m'tsogolomu. Kuwerengera kuchuluka kwa madzi otaya kuti muthe kuthana ndi chimbudzi chazaka 20 zikubwerazi. Komabe, kuthamanga kwaposachedwa sikungagwire ntchito pazotulutsa zambiri. Chifukwa chake, Proco ndi MCG ayenera kupanga valavu yoyenera yowunika kuti achepetse nkhawayi.
MCG inalimbikitsa kuti Water Authority igwiritse ntchito valavu ya Proco ProFlex 710 duckbill mu pulojekitiyi, ndi ma drain awiri a 10-inch pa doko lililonse. Vavu yoyang'ana kakhakha yokhala ndi m'mimba mwake (250 mm).
Valve ya duckbill imagwiritsidwa ntchito kuteteza kubweza m'malo otayira madzi am'madzi akuya / projekiti ya diffuser. The Proco ProFlex 710 duckbill check valve imapewa zipewa zakhungu pamadoko ena pazaka zingapo zoyamba kugwira ntchito. Kuonjezera apo, kugwiritsa ntchito ma valve a Proco ProFlex 710 duckbill check valves kumathetsa kufunika kwa ma flanges akhungu chifukwa mapaipi amatha kuyenda bwino kuyambira poyambira koyamba, potero amachepetsa ntchito yokonza ndikuchepetsa nthawi yoti anthu osiyanasiyana aziwonjezera ma valve owonjezera mtsogolo.
Valavu yoyendera duckbill imagwiritsidwa ntchito pantchitoyi kuteteza madzi amchere kuti asalowe mupaipi pomwe palibe mphamvu yolowera. Kuthamanga kwa mutu kukakhala kochepa kapena kulibe kulowera, kusiyana kwa kuthamanga kwamutu pakati pa madzi a m'nyanja ndi kukhetsa madzi kumapangitsa kuti madzi a m'nyanja alowe mupaipi. Ngati kubwerera kumbuyoku sikuletsedwa, doko likhoza kutsekedwa kapena kutsekedwa, ndipo zamoyo za m'madzi zikhoza kulowa m'mapaipi. Chotsatira chake, chiwerengero cha dilution chowerengeka komanso chopangidwira sichingapezeke. Valavu yoyang'anira duckbill imatha kukulitsa liwiro la jet ndikupereka mtengo wosiyana wosiyana ndi zipata zachikhalidwe, ngakhale pamayendedwe otsika.
Kuphatikiza apo, elastomer ya engineering ya Proco ProFlex 710 duckbill check valve imatha kusunga chikumbukiro chake itatha kutsegulidwa kapena kutsekedwa kwa nthawi yayitali, ndipo valavuyo ndi 100% kugonjetsedwa ndi barnacles ndi algae, yomwe ndi mbali yofunika kwambiri ya mchere wosungirako madzi. polojekiti. Gulu la engineering la Proco linaperekanso chithandizo chokwanira popereka mawerengedwe a kutaya mutu.
Mutatha kukhazikitsa Proco ProFlex 710 duckbill check valve, lembani msonkhano womalizidwa ndi mpweya kuti mukhalebe osangalala, ndikukokerani kumalo enaake, ndikuponya pansi pa nyanja. Izi zimayika valavu ya Proco 710 kuti igwire ntchito ndikulola kufalikira koyenera kwa ma valve 46. Dongosololi lakhala likugwira ntchito mokwanira m'derali, ndipo Proco ikupitilizabe kupereka chithandizo ndi chidziwitso chaukadaulo chofanana ndi dongosolo lino padziko lonse lapansi.
Ogwira ntchito ku Rainwater Solutions akuitana akatswiri amakampani kuti asankhe zomwe amawona kuti ndizabwino kwambiri komanso zatsopano zamapulojekiti amadzi ndi madzi oyipa omwe akuyenera kudziwika mu Buku Lothandizira Pachaka. M'miyezi 18 yapitayi, mapulojekiti onse akuyenera kukhala akupanga kapena kumanga.
