Insimbi yebholaivalvu yokuhlola amanziuhlobo lwevalvu olusetshenziswa ezinhlelweni zamapayipi, umsebenzi walo oyinhloko ukuvimbela i-medium ukuthi ingaphindeli emuva epayipini, kuyilapho ivikela iphampu kanye nohlelo lwamapayipi emonakalweni obangelwa yisando samanzi. Izinto zensimbi ezithambile zinikeza amandla amahle kakhulu kanye nokumelana nokugqwala, okwenza ifanelekele izimo zokusebenza ezahlukahlukene.

Umgomo wokusebenza wevalvu yensimbi ethambile engabuyi usekelwe ekwehlukeni kwengcindezi okubangelwa ukugeleza kwe-medium. Lapho i-medium igeleza phambili, ivalvu iyavuleka, okuvumela uketshezi ukuthi ludlule. Lapho i-medium izama ukugeleza ngokubuyela emuva, ibhola elingaphakathi kwevalvu lisunduzelwa esihlalweni sevalvu ngaphansi kwengcindezi ye-medium, ngaleyo ndlela livale ivalvu futhi livimbele i-medium ukuthi igeleze emuva. Lo mklamo uqinisekisa ukusebenza okuzenzakalelayo kwevalvu ngaphandle kwesidingo somthombo wamandla wangaphandle.

Izinzuzo zevalvu yokuhlola insimbi ethambile engabuyi zifaka:

1. Isakhiwo esiqinile: Uma kuqhathaniswa nama-valve okuhlola endabuko, ama-valve okuhlola insimbi ethambile anobude obufushane besakhiwo, ivolumu encane, isisindo esilula, futhi kulula ukuwafaka nokunakekela.

2. Ukusebenza kahle kokuvala: ukusebenzisa ama-flaps ebhola le-foreskin yerabha ukuze kuhlinzekwe umphumela omuhle wokuvala nokunciphisa ukuvuza.

3. Ukuvala: Uma kuvaliwe, kunganciphisa amagagasi amanzi, kwehlise umsindo, futhi kuvikele uhlelo lwamapayipi.

4. Ukumelana nokuguguleka: Ingqimba yokunamathela yesphere inokuqina okuhle kanye nokumelana nokuguguleka, okwandisa impilo yesevisi yevalvu.

5. Ukusebenza Okuqinile: Ingasetshenziswa ezindleleni ezahlukahlukene ezifana namanzi abandayo, amanzi ashisayo, indle yezimboni neyasekhaya, futhi ifanele ukufakwa okuvundlile noma okuqondile.

6. Yehlisa umphumela wesando samanzi: Umklamo wokuvala okusheshayo kusiza ekunciphiseni ukwenzeka kwesando samanzi nokuvikela uhlelo lwamapayipi.

7. Ukulungiswa okulula: izingxenye ezimbalwa, ukuqaqwa okulula, kanye nezindleko zokulungisa ezincishisiwe.

Ngakho-ke, ngenxa yokushisa okuphezulu, umfutho ophezulu, kanye nendawo egqwalisayo, i-ductile iron check valve engu-8 intshi isetshenziswa kabanzi embonini ye-petrochemical ukuvimbela ukugeleza okuphakathi nokuqinisekisa ukuphepha nokuzinza kwenqubo yokukhiqiza. Ohlelweni lokungena kanye nohlelo lwamanzi okuphakelwa kwe-turbine yomusi, ama-ductile iron check valve angavimbela nokugeleza okuphambene komusi kanye namanzi okuphakelwa, avikele ukusebenza okuvamile kweyunithi. Ezinye izimboni zifaka phakathi izinhlelo zamanzi zikamasipala kanye nokuthuthwa kwamanzi, izimboni zamakhemikhali nezemithi, ikakhulukazi embonini yokwelapha amanzi emvelo. Ohlelweni lokwelapha amanzi, ama-ductile iron check valve angavimbela ngempumelelo indle ukuthi ibuyele emuva futhi aqinisekise ukuphepha kwekhwalithi yamanzi.

I-Jinbin Valve ibilokhu igxile ekukhiqizweni kwamavalvu iminyaka engama-20. Njengomkhiqizi wamavalvu waseShayina, sigxila ocwaningweni nasekuthuthukisweni, siphishekela ukusungula izinto ezintsha, futhi senza yonke imizamo yokunikeza amakhasimende izixazululo ezifanele kakhulu. Imikhiqizo yethu eyinhloko ifaka phakathi amavalvu amasango enziwe ngokwezifiso,ivalvu yesango le-sluice,ivalvu yokunciphisa umoya, amavalvu amakhulu ebhabhathane, amavalvu amakhulu esango, ivalvu yensimbi engagqwali, nokuningi. Uma unezidingo ezihlobene namavalvu, sicela usithinte ngezansi. Silangazelela ukusebenza nawe!
