I-DN1800 enobubanzi obukhuluivalvu yedadainesakhiwo sokujonga esiguquguqukayo serabha yonke esivula size sivale ngokuzenzekelayo ngoxinzelelo oluphakathi. Xa kuthelekiswa neengcango zentsimbi eziqhelekileyo kunye neevalvu zokujonga iibhabhathane, inika iingenelo ezimangalisayo kwaye isetyenziswa kakhulu kwiiprojekthi ezinkulu zokugcina amanzi kunye nemibhobho yamanzi kamasipala.

Iingenelo zeeFlanged Rubber Duckbill Valves

1. Yakhiwe njengesixhobo esipheleleyo serabha engenazo izikhonkwane zoomatshini okanye iindawo zokuvula/zokuvala ezihambayo, ivalvu ayichaphazeleki kukugqwala nokubola. Nokuba inkunkuma, amatye okanye inkunkuma ihleli kwindawo yokuphuma kwevalvu, ukuthamba kwerabha kwenza ukuba ivalwe ngokuqinileyo, ngokusisiseko kususe iingxaki zokuxinana nokuvuza.

2. Ukuvula nokuvala kuqhutywa ngokupheleleyo kukwahluka koxinzelelo lolwelo ngaphandle kolawulo lombane okanye ukusebenza ngesandla. Isebenza ngokuthula ngaphandle kwengxolo erhabaxayo kwaye ifuna ukulahleka okuncinci kwentloko ukuze ivuleke, nto leyo enciphisa ukusetyenziswa kwamandla okukhupha amanzi.

3. Akukho mfuneko yokugcinwa rhoqo okanye ukuthambisa, ubomi benkonzo obungaphezu kweminyaka elishumi. Ifumaneka kwiidizayini zoqhagamshelo olune-flange kunye nolwe-socket-end, ingena kwiipayipi zentsimbi, iipayipi zekhonkrithi kunye neepayipi ezinkulu ze-FRP ukuze kube lula ukuzifaka kunye neendleko zeprojekthi eziphantsi.

4. Iikhompawundi zerabha ezikhethiweyo kuquka irabha ye-nitrile, i-neoprene kunye ne-EPDM zibonelela ngokumelana okuhle kakhulu ne-asidi, i-alkali kunye nokugqwala kwamanzi olwandle, zilungele iimeko zokusebenza ezinzima kunye nelindle, udaka kunye namanzi anetyuwa.

Ububanzi besicelo

Ivalvu idla ngokufakelwa kwiipayipi ezinkulu zokukhupha amanzi ezidolophini kunye neendawo zokukhupha amanzi amdaka kwizityalo ezinkulu zokucoca amanzi amdaka ukuthintela ukubuya kwamanzi ezikhukulayo angena elizweni ukuya kwizityalo nakwiinethiwekhi zemibhobho kamasipala ngexesha lezikhukula. Kwiidokhi zaselunxwemeni nakwiiprojekthi zokukhupha amanzi amdaka ezikunxwemeni, ithatha indawo yeengcango ezinkulu zentsimbi ukuthintela ukubuya kwamanzi olwandle. Ikwafakelwa kwiindlela zokuchitheka kwamanzi ezikwiindawo zokugcina amanzi kunye needykes kunye neziphelo zokuphuma kwezikhululo zokukhupha amanzi ukuqinisekisa ukukhutshwa kwamanzi amdaka aphezulu kunye nokuthintela ukuhamba kwamanzi amdaka xa iipompo zivaliwe. Ukongeza, isebenza njengesixhobo sokujonga indlela enye kwimigca yokukhupha amanzi emvula kwiindlela ezinkulu zokukhupha amanzi kunye nezikhululo zeenqwelo-moya, kunye nemigca yamanzi amdaka yemizi-mveliso yeepaki zeekhemikhali, ukuthintela ukuphuma kwevumba kunye nokukhusela iinethiwekhi zemibhobho ekubuyeni kwamanzi.

Ngamava angama-20 eminyaka yokuvelisa, iJinbin Valve igxile kuyilo olucwangcisiweyo kunye nemveliso yeevalvu zoshishino eziquka iigeyithi ze-sluice, iivalvu zekhowuni, iivalvu ezingaboniyo, ii-air dampers, iivalvu zebhabhathane, iivalvu zesango kunye neegeyithi ze-flap. Sinikezela ngenkxaso yobugcisa yomntu ngamnye kunye neevalvu ezenzelwe wena ukuze zihambelane neemeko zokusebenza ezithile zabathengi. Nceda ushiye umbuzo wakho apha ngezantsi ukuba unayo nayiphi na imfuneko, kwaye siya kuphendula zingadlulanga iiyure ezingama-24.
