I-valve yokunciphisa ingcindezi yendawo yokunciphisa insipho ye-air pre-heater
| Uhlobo | I-Valve Yokunciphisa Ingcindezi |
| Imodeli | Y666Y-P55 80Ⅰ, Y666Y-1500LB |
| Ububanzi Okuzisholo | I-DN 100 |
Ivalve yokunciphisa umule ka-600 kuya ku-1,000MW ebaluleke kakhulu (i-ultra-supercritical) pre-heater ithatha izinga lokushisa eliphezulu lokushisa kabusha isitimu njengomthombo womoya ophephetha umule. Ingcindezi incishiswa ngevalvu yokulawula yesiteshi sokunciphisa umule bese inikezwa isivuthela umule njengomthombo womoya ophephetha umule.
- Umzimba we-valve wamukela isakhiwo sokushisela esakhiwe ngamandla amakhulu futhi i-valve inamandla anele. Ngokwakheka kohlobo "Z", inomshini wokushisela izinqe ngepayipi.
- Ngesembozo sokugeleza okufanayo, i-valve inlet yenza ukugeleza okuphakathi ukusuka ku-periphery kuya engxenyeni ye-throttle ngokulinganayo ukuvimbela okuphakathi ukuthi kungahlikihli ingxenye yangaphakathi kanye nokuvala indawo ye-throttle ngokuqondile futhi kwandise impilo yesevisi yengxenye ye-throttle kanye nendawo yokuvala.
- Isihlalo se-valve sithatha ukuvaleka kwe-conical futhi i-valve core kanye nesihlalo sisebenzisa i-Stellite alloy spray welding ukwenza i-valve ibe nokumelana nokuhushulwa, ukumelana nokugqwala, ukunqanda ukubhoboza nezinye izici.
- I-valve core ithatha izinyathelo ezintathu zokunciphisa ukucindezela kwe-throttle futhi isinyathelo ngasinye se-throttle silawula ukucindezela kwamanzi ngaphezu kwesilinganiso esibucayi sokunciphisa ukucindezela, ukuvimbela ukulimala kwe-cavitation.
- Ngenketho eguquguqukayo, i-actuator enikezwe i-valve ingacushwa ngokwezidingo zabasebenzisi.
