Rerection valve mo te whakawhiti wai matua
| Momo | Rerection Valve |
| Tauira | T668Y-4500LB, T668Y-500, T668Y-630 |
| Diamita Ingoa | DN 300-400 |
Ka whakamahia mo te paipa whakawhiti wai matua o te 1,000MW supercritical (ultra-supercritical) kōhua wae mo te whakahaere i te rere o te wai.
- Ko te takirere he hanganga momo tika, ko te huarahi rerenga reo he momo rere me te mata hiri o te nohoanga takirere kei tawhiti atu i te waahi whakaetonga hiko o te hikoinga whakamutunga hei whakapumau i te oranga ratonga.
- Ko te tinana takirere me te potae ka tango i te hanganga maitai me te kaha nui kia pai ake ai te whakatutuki i nga whakaritenga kaha i raro i te pāmahana teitei me te pehanga.
- Ka tangohia e ia te hanganga o te nohoanga takirere ka taea te tango me te tuuru takirere he Stellite No.
- Ko te kōpae takirere ka mau i te hanganga taurite me te mata o te hiri ka mau te tiini auau teitei; Ko nga kohao o runga me raro o te kōpae takirere ka mohio ki te toenga pehanga ma te pore hono. I roto i tenei take, ka taea te kati i te paera e te taputapu taraiwa me te iti o te pana.
- Ko te waahanga o te kaareti o te matua takirere kua hangaia hei tango i te uhi 6-paparanga 5-taahiraa te pehanga whakaheke i te hanganga ki te whakamarara i te wai whenu kotahi me te kaha nui ki roto i te wai whenu maha me te iti o te kaha ki te whakaheke tere me te haruru. Ko te whakaheke i te pehanga taahiraa-i-te-taahiraa ka kitea e te dislocation aperture ki te whakakore i te cavitation. Ko te karekau kaupae whakamutunga ka rere atu te wai ma te ahunga raina paatata ka anga atu ki te kohao o roto o te tinana takirere hei whakaiti i te whiu ki te tinana takirere.
- Ko te hiri o te taha o waenga ka mau i te hanganga hiri-rua o te peera hiato niho ngaru me te whakakai rokiroki hiko rapa, kia pono ake ai te hiri.
- I raro i te ahua mahi o te rere iti me te pehanga rerekee nui, ka mauhia te karekau ringaringa maha-taahiraa me te whakaheke i te pehanga taahiraa-i-te-taahiraa ka kitea e te whakaritenga dislocation o te tuwhera me te diameter kore-rite ki te whakahaere i te tere o te rere reo me te whakaiti i te paanga o cavitation me te whakaetonga kohiko i runga i te takirere. I raro i te ahua mahi o te rere nui me te iti o te pehanga rereke, ka whakamahia te matapihi kotahi-taahiraa mo te whakaheke i te pehanga hei whakarite i te kaha rere o te paera.
- Ka pai ake nga ahuatanga o te ture kia rite ki te paiheneti, ka taea te whakahaere tika i te rere o te reo kia pai ai te mahi ture.
- Ka taea te whakakii i te puera ki te hiko hiko, ki te miihini pneumatic ranei kia mohio ai te whakatuwhera tere me te kati me te toru-tiaki.
