Ixhasa iprojekthi yenkulungwane "yokujika uMlambo iYangtze uye kuMlambo iHuaihe", i-TWS ibonelela ngesiqinisekiso "esiphambili" sokhuseleko lokunikezelwa kwamanzi

Njenge "Projekthi yeNombolo 1" yokunciphisa ukunqongophala kwamanzi kumantla e-Anhui nasempuma yeHenan, inkqubela phambili yokwakhiwa kweProjekthi yokuPhambuka koMlambo iYangtze ukuya kuMlambo iHuaihe itsale ingqalelo enkulu. Kutshanje, njengoko le projekthi itshintsha ukusuka kwinqanaba lokwakha ukuya kwinqanaba lokusebenza, iinkampani ezininzi eziphambili zeevalvu kushishino ziye zabandakanyeka kakhulu kule projekthi yale nkulungwane. Ngamandla ayo obuchwephesha abalaseleyo,Tianjin Tanggu Water-Seal Valve Co., Ltdwaphuma phambili kwibhidi enzima waza waba ngomnye wababoneleli beevalvu abaphambili kule projekthi.

Njengeprojekthi enkulu yenethiwekhi yamanzi kazwelonke edibanisa iinkqubo ezimbini ezinkulu zamanzi zoMlambo iYangtze kunye noMlambo iHuaihe, ukuphambukiswa koMlambo iYangtze ukuya kuMlambo iHuaihe kubeka iimfuno eziphezulu kakhulu ekuthembekeni nasekuqineni kwezixhobo ezibalulekileyo. Ingakumbi kwiindawo eziphambili ezifana neentambo eziphambili zokuhambisa amanzi kunye namasango okuphambukiswa kwamanzi ezityalo zamanzi, izixhobo zevalvu zifana "nevalvu yentliziyo" yomzimba womntu, enxulumene ngokuthe ngqo nokhuseleko kunye nokuzinza kokunikezelwa kwamanzi kumashumi ezigidi zabemi kulo mgca.

Kwimeko enjalo,Tianjin Tanggu Water-Seal Valve Co., Ltd.ixhomekeke ekuqokeleleni kwayo okukhulu kwicandelo lokuvelisa iivalvu ukuze iphumelele ngempumelelo kwibhidi yecandelo eliphambili lesigaba sesibini seProjekthi yokuPhambuka koMlambo iYangtze ukuya kuMlambo iHuaihe. Kule ntsebenziswano, i-TWS ibonelele kakhuluiivalvu zebhabhathane ezinobukhulu obukhulu, iivalvu zesangokunye nezixhobo ezincedisayo. Phakathi kwazo,iivalvu zebhabhathane, ngenxa yokuvula nokuvala kwazo okuguquguqukayo kunye nokumelana nolwelo oluphantsi, zisetyenziswa kakhulu ekwabiweni kwemithombo yamanzi kunye nolawulo lokuhamba kwamanzi kwiiprojekthi, zibonelela ngolawulo oluchanekileyo kunye nolawulo "lwamanzi omlambo ahamba emantla".

Ngokwengxelo yolwazi lukawonke-wonke, eli asiloxesha lokuqalaI-TWSithathe inxaxheba kwiprojekthi ephambili yesizwe yokuphambukisa amanzi. Iqokelele amava atyebileyo kwiinkonzo zokubonelela kunye nezobugcisa kwiiprojekthi ezinkulu ezifanayo zokugcina amanzi. Ngeli xesha ukuze ikhonze iYangtze River Diversion ukuya kuMlambo iHuaihe, iTWS ayiboneleli nje kuphela ngeemveliso zevalvu zeYangtze River Diversion ukuya kuMlambo iHuaihe, kodwa ikwaxhomekeke kwiqela leenkonzo zobungcali emva kokuthengisa ukusebenzisana nesikhokelo sokufakela kwindawo kunye nokulungisa iingxaki ukuqinisekisa ukusebenza okuzinzileyo kwexesha elide kwezikhululo zokumpompa kunye nemigca yokuhambisa amanzi.

Ukususela kuyilo lomzobo ukuya ekusetyenzisweni kwezixhobo,I-TWSisebenzisa imveliso enobuchule ukunceda "ukuhambisa amanzi acocekileyo ukusuka komnye umlambo ukuya emantla".iivalvu zebhabhathanekunye nezinye iimveliso ezibonelelayo zinegalelo “kumandla eevalvu” aqinileyo ekwakhiweni kweeprojekthi zenethiwekhi yamanzi yesizwe.
