Eshabhu laseJinbin, insimbi engagqwali engamamitha amabilii-valve yesango le-penstock efakwe esiteshiniIkhasimende lifaka futhi lilungisa amaphutha kagesi, kanti abasebenzi bahlola ukuvulwa nokuvalwa kwepuleti lesango. Isango le-penstock lesiteshi sensimbi engagqwali elingamamitha amabili (elinezinto ezivamile kuyinsimbi engagqwali engu-304/316L) liyidivayisi yokulawula eyinhloko eyenzelwe izimo zokuhambisa amanzi esiteshini esigeleza kakhulu. Ngezakhiwo zalo zezinto kanye nokwenza ngcono isakhiwo, libambe isikhundla esibalulekile emikhakheni efana nokugcinwa kwamanzi, imisebenzi kamasipala, kanye nezimboni.

Izici zayo eziyinhloko zigxile ezilinganisweni ezintathu: isakhiwo, ukuvala kanye nokusebenza: Isebenzisa ipuleti lesango elihlanganisiwe elihlanganisiwe kanye nohlaka lomnyango, oluncane futhi oluqinile kakhulu, olufanele izidingo zokulawula ukugeleza kweziteshi ezingamamitha amabili ububanzi, futhi alunawo umklamo ophindaphindayo. Uhlelo lokuvala lusebenzisa izivalo ezithambile zerabha noma izivalo zensimbi eziqinile, kuhlanganiswe namasu okucubungula anembile, okuqinisekisa ukulingana okuphezulu phakathi kwepuleti lesango nohlaka lomnyango, kufeza umphumela wokuvala ongenawo nhlobo. Imodi yokusebenza isekela izivalo eziphathwayo kanye nezivalo zikagesi (ngemoduli yokulawula ekude ongayikhetha), ivumelana nokusebenza okulula ngaphansi kwezimo zokusebenza ezahlukene. Imodeli kagesi inesivinini sokuphendula esisheshayo, kuyilapho imodeli yesandla inezindleko eziphansi zokulungisa.

Ivalvu ye-penstock yensimbi engagqwali inokumelana nokugqwala okunamandla kakhulu kanye nokumelana nokuguguleka. Ingamelana nokuguguleka kwemidiya eyinkimbinkimbi njengokugeleza kwamanzi ane-acidic kanye ne-alkaline kanye nokugeleza kwamanzi anesihlabathi. Impilo yayo yesevisi ide ngokuphindwe kathathu kuya kahlanu kunevalvu yesango lensimbi ejwayelekile yekhabhoni. Ububanzi obukhulu buhlangabezana nesidingo sokudluliselwa kwamanzi okugeleza okuphezulu, ngesigaba sokugeleza okubushelelezi kanye nokulahleka okuphansi kwe-hydraulic, okuqinisekisa ukusebenza kahle kokudluliselwa kwamanzi kwesiteshi. Umklamo wesakhiwo ucabangela kokubili ukufakwa kanye nokugcinwa. Ilula futhi kulula ukuyihlukanisa nokuyihlanganisa. Ukugcinwa kungaqedwa ngaphandle kwamathuluzi ayinkimbinkimbi, kunciphisa izindleko zokusebenza kanye nokugcinwa. Isebenza kahle kakhulu ekuvikeleni imvelo. Yenziwe ngensimbi engagqwali, ayibangeli ukungcola kwesibili futhi ihlangabezana nezindinganiso zokuvikela imvelo zokwelashwa kwamanzi okuphuza kanye nendle. Ngaphezu kwalokho, inokumelana okuzinzile okuphezulu nokuphansi kwezinga lokushisa futhi ifanele izimo zokusebenza ezimbi kakhulu ezisukela ku--20 ℃ kuya ku-80 ℃.

Izimo zokusetshenziswa zihlanganisa izimo zokusebenza eziyinhloko zezimboni eziningi: Emaphrojekthini okulondolozwa kwamanzi, isetshenziselwa ukulawulwa kwezinga lamanzi kanye nokulawulwa kokugeleza kwamanzi ekuphathweni kwemifula, ezindaweni zokuchitheka kwamanzi, kanye neziteshi zokunisela zasemapulazini, ezifanele kakhulu iziteshi ezinkulu zezifunda ezinkulu zokunisela kanye namaphrojekthi okuphambukisa amanzi anqamula izifunda. Emkhakheni wokuhlinzekwa kwamanzi kamasipala kanye nokudonswa kwamanzi, isetshenziswa kabanzi eziteshini zokungenisa kanye nokudonswa kwamanzi zezitshalo zokuhlanza indle, ekuvinjweni kwamanethiwekhi amanzi emvula, kanye neziteshi zokuthutha amanzi ezingavuthiwe zemisebenzi yamanzi, futhi ingalawula ngokunembile ukushintsha kokugeleza kwamanzi kanye nesivinini sokugeleza. Emkhakheni wezimboni, iyasebenza eziteshini zamanzi ezijikelezayo kanye neziteshi zokuhlanza amanzi amdaka ezimbonini zamakhemikhali, zamandla nezensimbi, imelana nokugqwala kwamanzi amdaka ezimbonini zamakhemikhali, zamandla nezensimbi, imelana nokugqwala kwamanzi amdaka ezimbonini futhi iqinisekise ukuzinza kokuhlinzekwa kwamanzi okukhiqiza.
