Ivalve yokulawula inqanaba lamanzi kwitanki yamanzi
| Uhlobo | Ivalve yokulawula |
| Umzekelo | T964Y-420Ⅰ, T964Y-500Ⅰ, T964Y-2500LB |
| Idayamitha yeNominal | DN 250-300 |
Isetyenziselwa ukulawula umgangatho wamanzi wetanki yamanzi ye-600 ukuya kwi-1,000MW supercritical (ultra-supercritical) iyunithi kunye nokuphumeza injongo yokulawula umgangatho wamanzi wetanki yamanzi ngokusebenzisa imingxuma eyahlukeneyo.
- Umzimba wevalvu wamkela ulwakhiwo olubunjiweyo olupheleleyo kunye namandla aphezulu kwaye ivalve ithatha uhlobo lwe-plunger yohlobo lokuhamba okuhamba kakuhle, olunobume kunye nomsebenzi wokuthintela ukungcola okuncinci kunye nento yangaphandle kumbhobho ekonakaliseni iindawo zangaphakathi zevalve.
- Undoqo wevalve wamkela iplagi yevalve emiselweyo ukulawula ulwelo ngokuqhubekayo. Ayinazo iimpawu zolawulo lwenyathelo eliyekayo levalve yemaze elaminethiweyo.
- Isihlalo sevalve sithatha ukutywinwa okucolisiweyo kunye nesiseko sevalve kunye nesitulo sevalve samkela iStellite alloy spray welding ukwenza ivalve ibe nokumelana nokudumba, ukumelana nokubola, ukuchasa kunye nezinye iimpawu, ezine-anti-cavitation kunye nokumelana ne-abrasion.
- Umkhono okhokelayo wohlobo lwekheji unokukhusela umzimba wevalvu ekudlekeni. Isakhiwo seringi esikhethekileyo esithintela ukungcola kunye nento yangaphandle ebambeleleyo ikhusela iplagi yevalve kunye neringi ekudlekeni.
- Umngxuma ombindi womzimba wevalvu wamkela ubume boxinzelelo lokuzitywina kwaye olo lwevalvu lunotywino olungcono emva kokuba lucinezelwe.
- Ngokhetho oluguquguqukayo, i-actuator efakwe ivelufa inokumiselwa ngokweemfuno zabasebenzisi.
