Namhlanje, umzi-mveliso we-Jinbin ugqibe ukupakishwa kwevalve yesango elikhulu le-DN700. Okuivalve yesango le-suliceiye yalungiswa ngobuchule kwaye yalungiswa ngabasebenzi, kwaye ngoku igcwele kwaye ilungele ukuthunyelwa kwindawo yayo.

Iivalvu zesango elikhulu elinedayamitha enkulu zineenzuzo zilandelayo:

I-1.Umthamo wokuhamba okunamandla: Uyilo lwe-diameter enkulu luvumela ukuba ubuninzi be-fluid budlule, ukunciphisa ukunyanzeliswa kwamanzi kunye nokuqinisekisa ukuthuthwa kwamanzi okugudileyo.

I-2.Ukusebenza kakuhle kokutywinwa: Ukusebenzisa izinto zokutywina ezikumgangatho ophezulu kunokuthintela ngokufanelekileyo ukuvuza kwamanzi kunye nokuqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo.

I-3.Easy ukusebenza: Ngokuqhelekileyo iqhutywe ngesandla okanye i-actuator yombane, ekulungele ukusebenza kwaye inokufezekisa ukuvulwa nokuvala ngokukhawuleza.

I-4.Ihlala iqinile kwaye inokwethenjelwa: Isakhiwo siqinile, siyakwazi ukumelana noxinzelelo olubalulekileyo kunye neempembelelo zempembelelo, kwaye sinobomi obude benkonzo.

Ivalve yesango yentsimbi enedayamitha enkulu idla ngokusetyenziswa kwezi meko zilandelayo:

1. Ubunjineli bolondolozo lwamanzi: Kumadama amakhulu, amadama kunye nezinye izibonelelo zogcino lwamanzi, iivalvu zesango ezinobubanzi obukhulu zisetyenziselwa ukulawula ukuphuma nokuphuma kwamanzi nokulawula amanqanaba amanzi.

2. Ubonelelo lwamanzi kunye nenkqubo yokuhambisa amanzi: Kwimibhobho yobonelelo lwamanzi ezidolophini kunye nemibhobho yokuhambisa amanzi, ivalve yesango yamanzi enobubanzi obukhulu ingasetyenziselwa ukulawula indlela eya ngakuye kunye nokuhamba kwamanzi, ukuqinisekisa ukusebenza okuqhelekileyo konikezelo lwamanzi kunye nokuhanjiswa kwamanzi.

3.Ishishini lePetrochemical: Kwiinkqubo zemibhobho kumashishini afana nepetroleum kunye neekhemikhali, iivalvu zesango ezinobubanzi obukhulu zisetyenziselwa ukulawula ukuhamba kolwelo kunye neegesi ezahlukeneyo, ukuthintela ukuvuza kunye neengozi.

I-4.Ishishini lamandla: Kwizityalo zamandla, izitishi kunye nezinye izixhobo zombane, iivalve zesango ezinobubanzi obukhulu zisetyenziselwa ukulawula ukuhamba kwamanzi afana namanzi okupholisa kunye nomphunga, ukuqinisekisa ukusebenza okuqhelekileyo kwezixhobo.

I-5.Ukucocwa kwe-Sewage: Kwiindawo zokucocwa kwamanzi amdaka, i-valve yesango ye-flange ene-diameter enkulu isetyenziselwa ukulawula ukuhamba kunye nesalathiso sombhobho wamanzi amdaka, ukuqinisekisa inkqubela phambili yenkqubo yokucocwa kwamanzi amdaka.

Ngoko ke,ivalve yesango yobubanzi obukhuluixabiso lisetyenziswe ngokubanzi kwiinkalo ezahlukeneyo ezifana nobunjineli bokugcinwa kwamanzi, unikezelo lwamanzi kunye neenkqubo zokuhambisa amanzi, iikhemikhali zepetroli, ishishini lamandla, kunye nokucocwa kwamanzi amdaka ngenxa yomthamo wabo oqinileyo wokuhamba, ukusebenza kakuhle kokutywinwa, ukusebenza lula, ukuqina, kunye nokuthembeka.
