Kutshanje, iivalvu ezimbini ezinkulu ezinkulu ezine-DN700 zithunyelwe ngempumelelo zivela kumzi-mveliso wethu weevalvu. Njengefektri yeevalvu yaseTshayina, ukuthunyelwa ngempumelelo kweJinbin kweevalvu ezinkulu ezine-soft seal gate kwakhona kubonisa ubuchule obubalaseleyo bomzi-mveliso ekwenzeni iivalvu ngokwezifiso.

Kutheni ukhetha ivalvu yesango elithambileyo elikhulu ngobukhulu?

Okokuqala,ivalvu yesango lesitywino esithambileyoZineengenelo zokusebenza kakuhle kokuvala kunye nokusebenza lula, ngelixa uyilo olukhulu luhlangabezana neemfuno ezithile zobunjineli zokulawula ukuhamba kwamanzi okuphezulu. Kwiinkqubo zokubonelela ngamanzi ezidolophini kunye nokuhambisa amanzi, iivalvu zesango ezithambileyo ezinkulu ezinobubanzi obukhulu zinokulawula ukuhamba kwamanzi ngokufanelekileyo, ziqinisekise ukunikezelwa kwamanzi okuzinzileyo kunye nokuhambisa amanzi okugudileyo. Kwiindawo zokunyanga amanzi amdaka, inokulawula ukuhamba kwamanzi amdaka ngokuthembekileyo kwaye inike inkxaso enamandla kwinkqubo yokunyanga amanzi amdaka. Kwiiprojekthi ezinkulu zoshishino ezifana namashishini eekhemikhali kunye namandla, okuivalvu yesango ejikelezileyoinokudlala indima ebalulekileyo ekufezekiseni ulawulo oluchanekileyo lweendlela ezahlukeneyo zokusasaza iindaba.

Itywina elithambileyo le-DN700 elikhulu ngobukhuluixabiso levalvu yesangoithunyelwe ngeli xesha iye yavavanywa ngokungqongqo komgangatho kwaye yaveliswa ngokuchanekileyo ngumzi-mveliso, iqinisekisa ukuthembeka kwayo kunye nozinzo ngexesha lokusetyenziswa.

Umzi-mveliso wethu uhlala uzimisele ukubonelela abathengi ngeenkonzo zeevalvu ezenzelwe wena ezikumgangatho ophezulu. Ukususela kuyilo ukuya kwimveliso, inyathelo ngalinye lilawulwa ngokungqongqo ukuze lihlangabezane neemfuno zobuqu zabathengi abahlukeneyo. Ngezixhobo zokuvelisa eziphambili, iqela lobuchwephesha lobuchwephesha, kunye nenkqubo yolawulo lomgangatho oluqinileyo, sifumene ukuqatshelwa ngabathengi abaninzi.

Ukuthunyelwa kwevalvu yesango ethambileyo etywiniweyo ngesandla enobubanzi obukhulu ngeli xesha akupheleli nje ekubeni yimpumelelo ebalulekileyo kumzi-mveliso, kodwa ikwabonelela ngenkxaso enamandla kuphuhliso lwamashishini anxulumene noko. Ndikholelwa ukuba kwixesha elizayo, njengomvelisi weevalvu zesango laseTshayina, iJinbin iya kuqhubeka iqhutywa bubuchule kunye nomgangatho, inika abathengi iimveliso zeevalvu ezikumgangatho ophezulu kwaye inegalelo elikhulu kuphuhliso lweshishini lokuvelisa iivalvu.
