Gxininisa NJENGOMzantsi ukuya kwiProjekthi yoThutho lwaManzi eMntla
2021-08-20
Ngomhla wama-28 kuMeyi ka-2020, ivalve efana ne-LIKE iphumelele ibhidi yeprojekthi yokuthengwa kweprojekthi ye-Neixiang yonikezelo lwamanzi lweprojekthi yokubonelela ngamanzi eNanyang kwindawo yokufumana amanzi eSouth-to-North Water Transfer kwiPhondo laseHenan, elibe negalelo ekunciphiseni ukunqongophala. kobutyebi bamanzi kumntla weTshayina, ukuqonda ulwabiwo olunengqiqo lwemithombo yamanzi, ukuqinisekisa uphuhliso oluzinzileyo loqoqosho noluntu nokwakha iziseko ezingundoqo zobuchule boluntu oluphila kakuhle ngendlela ejikelezayo. Isishwankathelo seProjekthi yoThutho lwaManzi eMazantsi ukuya eMntla umfanekiso weProjekthi yoThutho lwaManzi oluMazantsi ukuya eMntla yiprojekthi enkulu yogcino lwamanzi esebenza e-China. Imithombo yamanzi eyintabalala ekwi-Jianghuai River Basin yaseTshayina ikhutshelwa eMntla China nakuMntla-ntshona weTshayina, ngenjongo yokuguqula imeko yokuzaliswa kwamanzi eMzantsi kunye nembalela emantla kunye nokunqongophala okukhulu kobutyebi bamanzi emantla, nokukhuthaza uphuhliso olulungelelanisiweyo lwezoqoqosho, uluntu, abemi, oovimba kunye nokusingqongileyo eMzantsi naseMntla. Iprojekthi inqumla uMlambo iYangtze, uMlambo iHuaihe, uMlambo oMthubi kunye noMlambo i-Haihe. Yeyona projekthi inkulu yodluliselo lwamanzi ehlabathini, enotyalo-mali olungaphezulu kweebhiliyoni ezingama-500 zeeyuan. Ivalve ye-Eccentric hemispherical valve Eccentric hemispherical valve isetyenziswa kwiProjekthi yoThutho lwaManzi oluMazantsi ukuya eMntla. Ivalve ye-Eccentric hemispherical luhlobo olutsha lwevalve yebhola. Inezinye iingenelo ezikhethekileyo zesakhiwo sayo, njengokuthi akukho friction yokutshintsha, ukugqoka nzima kwetywina kunye ne-torque encinci yokuvula kunye nokuvala. Oku kunciphisa ubungakanani be-actuator. Ixhotyiswe nge-actuator yombane ejikelezayo emininzi, i-medium inokulungiswa kwaye inqunyulwe ngokuqinileyo. Isetyenziswa kakhulu kwi-petroleum, ishishini lemichiza, unikezelo lwamanzi asezidolophini kunye nokuhanjiswa kwamanzi kunye nezinye iimeko zokusebenza ezifuna ukunqunyulwa okungqongqo. Umgaqo osebenzayo wevalve ye-eccentric hemispherical valve Eccentric hemispherical valve yenza ivalve ingavalwanga okanye ivalwe ngokujikeleza ikhonkco levalve. I-valve yebhola ineenzuzo zokutshintsha ukukhanya kunye nomthamo omncinci. Ingenziwa ibe yi-diameter enkulu, ukutywinwa okuthembekileyo, isakhiwo esilula kunye nokugcinwa okufanelekileyo. Umphezulu wokutywina kunye nomphezulu we-spherical uhlala uvaliwe, okungekho lula ukuchithwa nguphakathi. Isetyenziswe ngokubanzi kumashishini ahlukeneyo. Iimpawu zemveliso yevalve ye-eccentric hemispherical ① Ivalve ye-eccentric hemispherical sisakhiwo esixhonywe phezulu. I-valve efakwe kumbhobho ingahlolwa ngokuthe ngqo kwaye ilungiswe kwi-intanethi, enokunciphisa ngokufanelekileyo ukuvalwa kwesixhobo kunye nokunciphisa iindleko. ② Ivalve ye-eccentric hemispherical iyisitulo esinye, esisusa ingxaki yokuba i-medium kwi-valve cavity ichaphazela ukhuseleko lokusetyenziswa ngenxa yokunyuka koxinzelelo olungaqhelekanga. ③ Isiqu sevalve esinoyilo lwetorque ephantsi kunye noyilo lwesakhiwo esikhethekileyo sinokuvulwa kwaye sivalwe ngokulula ngesiphatho esincinci kuphela. ④ Akukho ngxabano phakathi kokuvula nokuvala. Lo msebenzi uyisombulula ngokupheleleyo ingxaki yokuba ukutywinwa kwevalufa yemveli [/ wiki] kuchatshazelwa kukungqubana phakathi kokutywinwa komphezulu. ⑤ Isakhiwo sokutywinwa kwe-Wedge: ivalve itywinwe ngokucinezela i-wedge yebhola kwisihlalo sevalve ngamandla omatshini anikezelwe sisikhondo sevalve, ukuze ukusebenza kokutywinwa kwevalve kungachatshazelwa kukutshintsha koxinzelelo lokwahluka kombhobho, kunye nokutywinwa. ukusebenza kuqinisekiswa ngokuthembekileyo phantsi kweemeko ezahlukeneyo zokusebenza. ⑥ Isakhiwo esizicocayo somphezulu wokutywina wevalve ye-hemispherical eccentric. Xa ibhola ityekela kude nesihlalo sevalve, ulwelo olukumbhobho ludlula kumphezulu wokutywina webhola ngokulinganayo kwi-360 °, engaphelisi nje ukukrwalwa kwendawo yesitulo sevalve ngolwelo olunesantya esiphezulu, kodwa ikwakhukulisa kude. ukuqokelela kumphezulu wokutywina ukufezekisa injongo yokuzicoca. Kwinkulungwane entsha ye-21st, abantu NJENGABANTU baya kubambelela kumbono wenkampani "NJENGEhlabathini, umboneleli othembekileyo wezisombululo zolawulo lwamanzi ekhaya nakwamanye amazwe" kunye nefilosofi yeshishini elithi "umgangatho udala ixabiso", kwaye uqhubele phambili ngamandla "ngokungqongqo". , ecokisekileyo, esebenzayo kwaye esebenzayo" Kwaye uzame ukwakha ishishini lokufunda elineembono eziphambili. Kwaye uzimisele ukusebenza nabantu bokuqonda ukwenza igalelo elikhulu ekuthathweni kweshishini levalvu yaseTshayina kunye nenkqubela phambili yempucuko yabantu!
