Gxila kuPhrojekthi Yokudluliswa Kwamanzi Enyakatho NJENGOBA

Ngomhla zingama-28 kuNhlaba wezi-2020, i-valve efana ne-LIKE iwine isicelo sokuthengwa kwephrojekthi yephrojekthi yokuhlinzeka ngamanzi e-Neixiang yephrojekthi esekela ukuphakelwa kwamanzi eNanyang endaweni ethola amanzi e-South-to-North Water Transfer esifundazweni sase-Henan, esibe nesandla ekwehliseni ukushoda. wemithombo yamanzi enyakatho yeShayina, ukufeza ukwabiwa okuphusile kwemithombo yamanzi, ukuqinisekisa intuthuko esimeme yomnotho nomphakathi kanye nokwakha ingqalasizinda yamasu amakhulu omphakathi ophila kahle ngendlela yawo wonke. Uhlolojikelele Lomsebenzi Wokudluliswa Kwamanzi AseNingizimu-Kuya-eNyakatho Isithombe Sokuphakelwa Kwephrojekthi Iphrojekthi Yokudluliswa Kwamanzi AseNingizimu-Kuya-eNyakatho iphrojekthi enkulu yokonga amanzi esebenza eShayina. Imithombo yamanzi echichimayo e-Jianghuai River Basin yaseChina idluliselwa eNyakatho yeShayina naseNyakatho-ntshonalanga yeChina, kuhloswe ngayo ukuguqula isimo sokugcwala kwamanzi eNingizimu nesomiso enyakatho kanye nokushoda okukhulu kwemithombo yamanzi enyakatho, futhi kugqugquzelwe ukuthuthukiswa komnotho okudidiyelwe, umphakathi, inani labantu, izinsiza kanye nemvelo eNingizimu naseNyakatho. Lo msebenzi uwela umfula iYangtze, umfula iHuaihe, umfula ophuzi kanye nomfula i-Haihe. Iwuhlelo olukhulu kunazo zonke lokudluliswa kwamanzi phakathi kwezigodi emhlabeni, olutshalwe imali engaphezu kwezigidigidi ezingama-500 zamayuan. I-Eccentric hemispherical valve I-Eccentric hemispherical valve isetshenziswa kuProjekthi Yokudlulisa Amanzi AseNingizimu-kuya-eNyakatho. I-Eccentric hemispherical valve iwuhlobo olusha lwe-valve yebhola. Inezinzuzo ezithile eziyingqayizivele zesakhiwo sayo, njengokuthi akukho ukungqubuzana kokushintsha, ukuguga okunzima kwe-seal kanye ne-torque encane yokuvula nokuvala. Lokhu kunciphisa usayizi we-actuator. Ifakwe i-multi rotation electric actuator, okuphakathi kungalungiswa futhi kunqanyulwe ngokuqinile. Isetshenziswa kakhulu ku-petroleum, imboni yamakhemikhali, ukuhlinzekwa kwamanzi emadolobheni kanye ne-drainage nezinye izimo zokusebenza ezidinga ukunqanyulwa okuqinile. Isimiso sokusebenza se-eccentric hemispherical valve valve Eccentric hemispherical valve yenza ivalve ingavimbeki noma ivinjwe ngokuzungezisa iketango lamavalvu. I-valve yebhola inezinzuzo zokushintsha ukukhanya kanye nevolumu encane. Ingenziwa ibe ububanzi obukhulu, ukubekwa uphawu okuthembekile, isakhiwo esilula nokugcinwa okulula. Indawo yokuvala kanye nendawo eyindilinga kuvame ukuvalwa, okungelula ukuguguleka yi-medium. Isetshenziswe kabanzi ezimbonini ezihlukahlukene. Izici zomkhiqizo ze-eccentric hemispherical valve ① I-eccentric hemispherical valve iyisakhiwo esibekwe phezulu. I-valve efakwe epayipini ingahlolwa ngokuqondile futhi ilungiswe ku-inthanethi, okunganciphisa ngempumelelo ukuvala ucingo futhi kunciphise izindleko. ② I-valve ye-hemispherical eccentric iyidizayini yesihlalo esisodwa, eqeda inkinga yokuthi i-medium ku-valve cavity ithinta ukuphepha kokusetshenziswa ngenxa yokwenyuka kwengcindezi okungavamile. ③ Isiqu se-valve esinomklamo we-torque ephansi kanye nomklamo wesakhiwo okhethekile singavulwa futhi sivalwe kalula ngesibambo esincane kuphela. ④ Akukho ukungqubuzana phakathi kokuvula nokuvala. Lo msebenzi uyixazulula ngokuphelele inkinga yokuthi ukuvalwa kwe-valve yendabuko [/ wiki] kuthintwa ukungqubuzana phakathi kwezindawo zokuvala. ⑤ Isakhiwo sokuvala i-valve: i-valve ivalwa ngokucindezela i-wedge yebhola esihlalweni se-valve ngamandla omshini anikezwe isiqu se-valve, ukuze ukusebenza kokuvala kwe-valve kungathinteki ngokushintsha kwengcindezi yokuhlukanisa ipayipi, kanye nokuvala uphawu. ukusebenza kuqinisekisiwe ngokuthembekile ngaphansi kwezimo ezihlukahlukene zokusebenza. ⑥ Isakhiwo esizihlanzayo sendawo yokuvala yevalvu ye-hemispherical eccentric. Lapho ibhola litshekela kude nesihlalo se-valve, uketshezi olusepayipini ludlula endaweni evalekayo yebhola ngokulinganayo ku-360 °, okungagcini nje ngokuqeda ukukhuculwa kwendawo kwesihlalo se-valve ngoketshezi olunesivinini esikhulu, kodwa futhi luyakhukhula. ukunqwabelana endaweni yokuvala ukuze kuzuzwe inhloso yokuzihlanza. Ekhulwini elisha lama-21, NJENGOBA abantu bazobambelela embonweni webhizinisi othi "NJENGOBA emhlabeni, umhlinzeki othembekile wezixazululo zokulawula uketshezi ekhaya naphesheya" kanye nefilosofi yebhizinisi ethi "ikhwalithi idala inani", futhi iqhubekele phambili ngamandla "eqinile , ecophelelayo, esebenzayo futhi esebenzayo" Futhi lwela ukwakha ibhizinisi lokufunda elinemibono ehamba phambili. Futhi uzimisele ukusebenzisana nabantu abanokuqonda ukwenza igalelo elikhulu ekususeni imboni ye-valve yaseShayina kanye nenqubekelaphambili yempucuko yabantu!
