Valve yowongolera mulingo wamadzi wa tanki yamadzi
| Mtundu | Valve yowongolera |
| Chitsanzo | T964Y-420Ⅰ, T964Y-500Ⅰ, T964Y-2500LB |
| Nominal Diameter | DN 250-300 |
Amagwiritsidwa ntchito poyang'anira kuchuluka kwa madzi a tanki yamadzi ya 600 mpaka 1,000MW supercritical (ultra-supercritical) ndikukwaniritsa cholinga chowongolera kuchuluka kwa madzi a thanki yamadzi kudzera m'mipata yosiyanasiyana.
- Thupi la valavu limatenga mawonekedwe opangidwa ndi mphamvu zambiri ndipo valavu imatenga mawonekedwe amtundu wa plunger ndi njira yodutsa yosalala, yokhala ndi kapangidwe kake ndi ntchito yoteteza zonyansa zazing'ono ndi zinthu zakunja mu chitoliro kuti zisawonongeke mkati mwa valavu.
- Pakatikati pa valve imatenga pulagi yopangidwa ndi valve kuti ilamulire madzimadzi mosalekeza. Ilibe mawonekedwe opitilira masitepe a maze laminated valve.
- Mpando wa valavu umatengera kusindikiza kwa conical ndipo mpando wa valve ndi mpando wa valve umatenga kuwotcherera kwa Stellite alloy spray kuti valavu ikhale ndi kukana kwa abrasion, kukana kwa dzimbiri, anti-scouring ndi zina, zomwe zimakhala ndi anti-cavitation ndi abrasion resistance.
- Nkhola yolondolera mtundu wa khola imatha kuteteza thupi la valve kuti lisawonongeke. Kapangidwe ka mphete kapadera kamene kamateteza kusadetsedwa ndi chinthu chakunja kukakamira kumateteza pulagi ya valve ndi mphete kuti zisawonongeke.
- Pakatikati pa thupi la valavu imagwiritsa ntchito makina odzisindikizira okha ndipo ya valve imakhala ndi chisindikizo chabwino ikakanikizidwa.
- Ndi njira yosinthika, actuator yoperekedwa ndi valavu imatha kukhazikitsidwa malinga ndi zofuna za ogwiritsa ntchito.
