I-Power Station Attemperating Water Control Valve
Imodeli 1
Izici:
Nge-throttling ebanzi yangaphakathi ye-multistage, umkhono wohlobo lwekheji odonsayo ufaniswe nohlobo lwenaliti ebanzi, engakwazi ukumelana nokucindezela okukhulu okuhlukile.Isihlalo sokulungisa sicindezelwe futhi sivalwe ngokuzimela, futhi indawo yokubeka uphawu ye-conical inokwethenjelwa.Ingafaniswa nengqikithi yokulungisa engalingani ukuze kuzuzwe ukuvuza okuyiziro.Ingxenye yangaphakathi iqiniswe ngensimbi engagqwali, ekwazi ukumelana nokuguguleka futhi inomsebenzi omude wenkonzo.Umehluko wengcindezi yesiteji esisodwa uncishisiwe uma kuqhathaniswa, ukuze ububanzi bokulawula bunwetshwe.Ikakhulukazi ekugelezeni okuncane, kusenokusebenza okuhle kokulawula.Ukwehla kokucindezela kwesiteji ngasinye kuzolawulwa ngaphakathi komehluko obalulekile wengcindezi ngaphandle kwe-cavitation kanye ne-flash.Imvume enokulungiswa okuyisisekelo inengqondo, futhi umkhono womhlahlandlela ufakwe ukusebenza okuhle komhlahlandlela nokusebenza okuzinzile.I-valve iyaguquguquka ekusebenzeni futhi inembile ekulungiseni.
Izicelo:
I-boiler overheater, reheater, fafaza isistimu yokushisa ukushisa, i-low pressure bypass water spray system desuperheating system.Isistimu yokushisisa isifutho samanzi kanye nesilawuli sokucindezela semikhiqizo eshisa ukushisa nesigaba.I-valve iyakwazi ukulungisa ukugeleza okuncane, ngobubanzi obukhulu bokulungisa nokusebenza okuzinzile.

Imodeli 2
I-Power Station High Pressure Minimum Flow Control Valve
Izici:
I-valve ingalungiswa ngokuqhubekayo ngaphakathi kobubanzi bokucindezela okuphezulu okuhlukile;I-Multi stage throttling iyamukelwa, i-medium iyancipha kancane kancane, futhi ukwehla kwengcindezi yesiteji ngasinye kungaphakathi kwebanga lokwehla kwengcindezi ye-gasification, ngokumelana ne-cavitation nomsindo ophansi.Ukulungiswa okuyisisekelo kusebenzisa isakhiwo somgwaqo esingasicaba, esinesihlalo se-monotone kanye nophawu olucijile, olusebenza kahle lokuvala futhi olungafinyelela ukuvuza kwe-zero pool.Isakhiwo se-sleeve siwuhlobo lwe-porous cage, futhi izimbobo ezincane zihlelwe ngokuqinile ngokuvumelana nezici zokulungisa ezidingekayo.Ngokusebenzisana okunengqondo phakathi kwe-valve core kanye nesihlalo sokulungisa imikhono, inqubo yokulungisa inokuvuza okuncane, nokulungiswa ngokunembile.Izingxenye ezingenhla nezingezansi zomongo wokulungisa zifakwe imikhono eqondisayo, eqinisekisa ukulungiswa okuzinzile, akukho ukudlidliza, nekhono eliqinile lokuzihlanza.Isakhiwo se-labyrinth, ukugeleza kwe-axial okuphakathi, ukunciphisa ingcindezi yesinyathelo ngesinyathelo nge-multistage throttle disc, ukumelana nophethiloli, umsindo ophansi nokusebenza okuzinzile.
Izicelo:
Ivalvu elawula ukugeleza okuncane isetshenziselwa ukubuyisela ingxenye yokugeleza ethangini le-deaerator lapho umthwalo weyunithi umncane ukuvimbela iphampu yokuphakelayo ekushiseni ngokweqile kanye nokufakwa kwegesi, nokuqinisekisa ukusebenza okuvamile kwephampu yokuphakelayo.Le valve ithuthukiswe ngokuyinhloko futhi yenzelwe izici zomehluko omkhulu wengcindezi yokuphakela kabusha, izimo ezimbi zokusebenza, izinga lokugeleza eliphakathi nendawo, nokuguguleka okukhulu kanye ne-cavitation yezingxenye zangaphakathi.Ingasetshenziswa kanye namaphampu okuphakelayo kubhayela angu-100MW/125MW/200MW/500MW.

Imodeli 3
I-Power Station High Pressure Water Control Valve
Izici:
Isembozo se-valve samukela isakhiwo sokuvala esimhlophe noma uhlobo lwe-flange, ukulungiswa komgogodla we-sleeve plunger core, isihlalo esisodwa se-cone seal, kanye nezinga eliphezulu lokuvuza.Indawo yokubeka uphawu yenziwe nge-carbide enosimende, futhi ingaphezulu lengxenye engaphakathi lifafazwa ngento eyodwa ephikisana nomthelela, enempilo ende yenkonzo.Uphawu luyi-gasket yesilonda sensimbi kanye noyinki wetshe oguquguqukayo oqinisiwe, ukubekwa uphawu okuthembekile.
Izicelo:
Isetshenziselwa ukulawula ukugeleza kwamanzi, ngokuvaleka okuthembekile, izinga lokuvuza eliphezulu kanye nempilo ende yesevisi.I-bypass yokuhlinzeka ngamanzi, i-spray des superheating system.Umthetho oyinhloko wokuhlinzekwa kwamanzi ku-boiler.
