Umfutholuketshezi-indlela ezintathu valve amanzi okuphakelayo ingcindezi
| Thayipha | Izindlela ezintathu Valve |
| Imodeli | I-F763Y-2500LB, F763Y-320, F763Y-420 |
| Ububanzi bokuqanjwa | I-DN 350-650 |
Ngesikhathi sokusebenza okujwayelekile kwe-heater ephezulu engu-600 kuye ku-1,000MW iyunithi yamandla kagesi ashisayo (i-ultra-supercritical), umzila omkhulu we-valve yezindlela ezintathu endaweni yokufaka umfutho ophakeme uvulwa futhi ukudlula kuvaliwe. Ukuphakelwa kwamanzi kubhayela kufaka ukungena ku-heater ephezulu kusuka emzileni omkhulu ngaphambi kokungena kubhayela nge-valve yezindlela ezintathu endaweni yokushisa ephezulu yokushisa.
- Umzimba we-valve nebhonethi yamukela isakhiwo sensimbi esakhiwe ngokuphelele.
- Uhlobo lokuvala lomzimba we-valve nebhonethi isebenzisa ingcindezi yokuzivala.
- Phezulu kwebhonethi ye-valve inezimbobo zokujova amanzi nezokuhambisa amanzi kanti ne-piston yakhiwe kubhonethi ye-valve.
- Ukufakwa uphawu kokufakwa kwesihlalo se-valve nediski kwamukela insimbi yokushisela ye-Stellite No. 6.
- Ukufakwa uphawu kokudlula kusebenzisa isakhiwo sokubekwa uphawu esihlanganisa indandatho yokugcina amandla e-PTFE eguquliwe ne-perfluoro O-ring.
- Izakhi ze-mpintsha ezifakweni ze-valve ezihamba ngezindlela ezintathu nesihlalo se-valve esingenhla zamukela ukwakheka okuhlanganisiwe futhi azidingi i-throttle orifice eyengeziwe ngokwehlukana.
