Pressure reduction valve mo te rehu pupuhi teihana whakaheke o te hau i mua i te whakamahana
| Momo | Pressure Whakaiti Valve |
| Tauira | Y666Y-P55 80Ⅰ, Y666Y-1500LB |
| Diamita Ingoa | DN 100 |
Ko te 600 ki te 1,000MW te whakawera o te hau i mua i te whakamahana o te rangi he nui te wera o te werawera hei puna hau e pupuhi ana. Ka whakahekehia te pehanga e te paera whakahaere mo te teihana whakaheke i te pupuhi ka tukuna ki te pupuhi pupuhi hei puna hau pupuhi.
- Ko te tinana takirere e tango ana i te hanganga fehokotaki me te kaha nui, a he rawaka te kaha o te takirere. Ki te hanganga momo "Z", he reke te hononga ki te putorino.
- Ma te uhi o te rere orite, ka rere tika te kurupae takirere mai i te taha ki te wahanga throttle kia kore ai e werohia te wahanga o roto me te hiri o te mata o te throttle me te whakaroa i te oranga o te waahanga throttle me te mata hiri.
- Ko te nohoanga takirere ka tango i te hiri hiri me te matua o te takirere me te nohoanga ka mau i te Stellite koranu rehu rehu fehokotaki'anga ki te hanga i te takirere mau abrasion ātete, waikura ātete, anti-parapara me etahi atu ahuatanga.
- Ko te matua takirere e tango ana i te toru-taahiraa te whakaheke i te pehanga throttle me ia hikoi o te throttle te whakahaere i te pehanga wai i runga ake i te owehenga whakaheke pehanga nui, hei aukati i te kino o te cavitation.
- Ma te kowhiringa ngawari, ka taea te whirihora i te kaitahuri kua oti te whakakakahu ki te takirere kia rite ki nga hiahia a nga kaiwhakamahi.
