Ivalve eneendlela ezintathu zeHydraulic yokubonelela ngamanzi kwisifudumezi soxinzelelo oluphezulu
| Uhlobo | Indlela ezintathu iValve |
| Umzekelo | F763Y-2500LB, F763Y-320, F763Y-420 |
| Idayamitha yeNominal | DN 350-650 |
Ngethuba lokusebenza okuqhelekileyo kwe-heater ephezulu ye-600 ukuya kwi-1,000MW i-supercritical (i-ultra-supercritical) iyunithi yamandla e-thermal, indlela ephambili ye-valve yeendlela ezintathu kwi-inlet ye-heater yoxinzelelo oluphezulu ivuliwe kwaye i-bypass ivaliwe. Ukunikezelwa kwamanzi kwibhoyila kungena kwisifudumezi soxinzelelo oluphezulu ukusuka kwindlela ephambili ngaphambi kokungena kwibhoyila ngevalve yeendlela ezintathu kwindawo yokukhupha isifudumezi soxinzelelo oluphezulu.
- Umzimba wevalve kunye nebhonethi zamkela ubume bentsimbi obunjwe ngokupheleleyo.
- Uhlobo lokutywina lomzimba wevalve kunye nebhonethi ithatha imo yoxinzelelo yokuzitywina.
- Umphezulu webhonethi yevalve unenaliti yamanzi kunye nemingxuma yokukhupha amanzi kwaye ipiston yakhiwe kwibhonethi yevalvu.
- Imiphezulu yokutywina yesitulo sevalve kunye nediski yamkele i-Stellite No. 6 ye-alloy spray welding.
- Ukutywinwa kwe-bypass kusebenzisa isakhiwo sokutywina esidibanisa i-PTFE eguquliweyo yokugcina amandla e-eneji kunye ne-perfluoro O-ring.
- Izinto ze-throttle kwi-inlet yevalve yeendlela ezintathu kunye nesihlalo sevalve ephezulu zamkela uyilo oludibeneyo kwaye akukho mfuneko yokongeza i-throttle orifice ngokwahlukeneyo.
