Namuhla, imboni yakwaJinbin iqedele ukupakishwa kwevalvu yesango engusayizi omkhulu we-DN700. Lokhui-valve yesango le-suliceiye yapholishwa ngokucophelela futhi yalungiswa amaphutha ngabasebenzi, futhi manje igcwele futhi isilungele ukuthunyelwa lapho iya khona.

Ama-valve amasango amakhulu anezinzuzo ezilandelayo:

I-1.Umthamo wokugeleza oqinile: Umklamo wobubanzi obukhulu uvumela inani elikhulu loketshezi ukuba lidlule, linciphise ukumelana noketshezi futhi liqinisekise ukuthuthwa koketshezi olubushelelezi.

2.Ukusebenza okuhle kokuvala: Ukusebenzisa izinto zokuvala zekhwalithi ephezulu kungavimbela ngempumelelo ukuvuza koketshezi futhi kuqinisekise ukusebenza okuphephile kwesistimu.

I-3.Kulula ukusebenza: Ngokuvamile kuqhutshwa i-handwheel noma i-actuator kagesi, elula ukuyisebenzisa futhi ingafinyelela ukuvulwa nokuvala okusheshayo.

4.Iqinile futhi ithembekile: Isakhiwo siqinile, siyakwazi ukumelana nokucindezela okukhulu namandla omthelela, futhi sinempilo ende yesevisi.

I-valve yesango yensimbi enobubanzi obukhulu ivame ukusetshenziswa kulezi zimo ezilandelayo:

1.Ubunjiniyela bokongiwa kwamanzi: Emadamini amakhulu, amadamu kanye nezinye izinsiza zokonga amanzi, amavalvu esango anobubanzi obukhulu asetshenziswa ukulawula ukungena nokuphuma kwamanzi kanye nokulawula amazinga amanzi.

2.Isistimu yokuphakelwa kwamanzi kanye ne-drainage: Emapayipini okuphakelwa kwamanzi asemadolobheni kanye namapayipi amanzi, ivalvu yesango lamanzi enobubanzi obukhulu ingasetshenziswa ukulawula indlela kanye nokugeleza kwamanzi, kuqinisekiswe ukusebenza okujwayelekile kokuphakelwa kwamanzi kanye nokukhipha amanzi.

3.Imboni ye-Petrochemical: Ezinhlelweni zamapayipi ezimbonini ezifana ne-petroleum namakhemikhali, amavalvu esango anobubanzi obukhulu asetshenziselwa ukulawula ukuhamba koketshezi oluhlukahlukene namagesi, ukuvimbela ukuvuza nezingozi.

I-4.Imboni yamandla: Ezitshalweni zikagesi, iziteshi ezingaphansi nezinye izinsiza zamandla, ama-valve esango anobubanzi obukhulu asetshenziselwa ukulawula ukugeleza koketshezi olufana namanzi okupholisa nesitimu, ukuqinisekisa ukusebenza okuvamile kwemishini.

I-5.Ukwelashwa kwendle: Ezitshalweni zokuhlanza indle, i-valve yesango ye-flange enobubanzi obukhulu isetshenziselwa ukulawula ukugeleza nokuqondiswa kwendle, ukuqinisekisa ukuqhubeka kahle kwenqubo yokuhlanza indle.

Ngakho-ke,i-valve yesango enobubanzi obukhuluintengo isetshenziswe kabanzi emikhakheni ehlukahlukene efana nobunjiniyela bokongiwa kwamanzi, izinhlelo zokuhlinzeka ngamanzi kanye ne-drainage, amakhemikhali e-petrochemicals, imboni yamandla kagesi, nokuhlanza indle ngenxa yomthamo wokugeleza okuqinile, ukusebenza kahle kokuvala, ukusebenza okulula, ukuqina, nokuthembeka.
