Uyazi bona ngimaphi amavalvu asetjenziswa khulu emaphrojekthini wokuhlanza amanzi?

Umnqopho wokuhlanza amanzi kuthuthukisa ikhwalithi yamanzi nokwenza bona ahlangabezane namazinga athileko wekhwalithi yamanzi.
Ngokuya ngeendlela ezihlukahlukeneko zokuhlanza, kunendlela yokuhlanza amanzi, ukuhlanza amanzi ngamakhemikhali, ukuhlanza amanzi ngezinto eziphilako nokunye.
Ngokuya ngezinto ezihlukileko zokuhlanza, kunemihlobo emibili yokuhlanza amanzi nokuhlanza amanzi asilapheleko. Ukuhlanzwa kwamanzi kufaka hlangana ukuhlanzwa kwamanzi wokusela wangekhaya nokuhlanzwa kwamanzi webubulo; ukuhlanzwa kwamanzi angcolileko kuhlukaniswe kwaba kuhlanzwa kwamanzi angcolileko wangekhaya nokuhlanzwa kwamanzi angcolileko webubulo. Hlangana nazo, ukuhlanzwa kwamanzi wokudla kwebhoyila, ukuhlanzwa kwamanzi wokwenza, ukuhlanzwa kwamanzi we-steam turbine main condensate kanye nokuhlanzwa kwamanzi ajikelezako, njll., zihlobene khulu nethekhnoloji yokutjhisa. Ukuhlanzwa kwamanzi kuqakatheke khulu ekuthuthukisweni komkhiqizo webubulo, ukwenza ngcono ikhwalithi yomkhiqizo, ukuvikelwa kwebhoduluko labantu nokugcinwa kokulingana kwemvelo.
Ubunjiniyela bokuhlanza amanzi yiphrojekthi yokuhlanza, ukuthambisa, ukubulala amagciwane, ukususa insimbi ne-manganese, ukususa ama-ayoni wensimbi ebudisi, nokuhlunga amanzi angahlangabezani neemfuneko. Ukubeka ngamagama alula, "ubunjiniyela bokuhlanza amanzi" yiphrojekthi yokususa ezinye izinto ezingatlhogeki ekukhiqizeni nepilo emanzini ngeendlela eziphathekako nezamakhemikhali. Kuzokuhlala nokuhlunga amanzi ngeenhloso ezithileko. , ukuhlanganiswa, ukuhlanganiswa, kanye nephrojekthi yokulungiselela ikhwalithi yamanzi njengokuvimbela ukugqwala nokuvimbela isikali.
Ngimaphi amavalvu wobunjiniyela bokuhlanza amanzi?
Ivalvu yesango: Umsebenzi wayo kukuvala ukugeleza kwamanzi, begodu ivalvu yesango lesiqu esikhuphukako lingakghona ukubona ukuvuleka kwevalvu ukusuka ekuphakameni kwesiqu sevalvu.
Ivalvu yebholo: isetjenziselwa ukusika, ukusabalalisa nokutjhugulula indlela yokugeleza okuphakathi. Ngeenhloso ezijayelekileko ukuvula/ukuvala amavalvu. Akukafaneli ukusetjenziswa njenge-throttle valve, kodwana ingasetjenziselwa ukwehlisa umfutho ongena nofana ophumako erherhweni lokha nayivulekileko.
Ivalvu ye-globe: Umsebenzi omkhulu wepayipi lokuhlanza amanzi kukuvala nofana ukuhlanganisa uketshezi. Ukugeleza okulawulako kwephasiivalvuingcono kunaleyo yevalvu yesango, kodwana ivalvu ye-globe angeze yasetjenziselwa ukulungisa umfutho nokugeleza isikhathi eside, ngaphandle kwalokho, indawo yokuvala ye-globe valve ingahlanzwa yi-Corrosion ephakathi, ilimaze ukusebenza kokuvala.
Ivalvu yokuhlola: isetjenziselwa ukukhandela ukubuyela emuva kwemidiyaukuhlanza amanziamapayipi nemitjhini.
Ivalvu ye-butterfly: ukusika nokugandeleleka. Lokhaivalvu yevivaneisetjenziselwa ukusika, iimvalo ze-elastic zisetjenziswa khulu, begodu izinto ezisetjenziswako yirabha, iplastiki, njll. Lokha nazisetjenziselwa ukugandelela, iimvalo eziqinileko zensimbi zisetjenziselwa khulu.
