Valavu yochepetsera mphamvu yochepetsera mwaye pochepetsa mpweya wotenthetsera
| Mtundu | Valve Yochepetsa Kupanikizika |
| Chitsanzo | Y666Y-P55 80Ⅰ, Y666Y-1500LB |
| Nominal Diameter | Chithunzi cha DN100 |
Vavu yochepetsera mwaye ya 600 mpaka 1,000MW supercritical (ultra-supercritical) pre-heater imatenga kutentha kwambiri kutenthetsanso nthunzi ngati gwero la mpweya. Kupsyinjika kumachepetsedwa ndi valavu yowongolera mwaye pochepetsera mwaye ndikuperekedwa ku chowuzira mwaye ngati gwero la mpweya wowuzira mwaye.
- Thupi la valavu limatenga mawonekedwe opangira kuwotcherera ndi mphamvu zambiri ndipo valavu imakhala ndi mphamvu zokwanira. Ndi mawonekedwe amtundu wa "Z", imakhala ndi kuwotcherera matako ndi chitoliro.
- Ndi chivundikiro choyenda chofanana, cholowera cha valve chimapangitsa kuyenda kwapakati kuchokera pamphepete kupita ku gawo la throttle mofanana kuti ateteze sing'anga kuti isalowe mkati ndi kusindikiza pamwamba pa throttle mwachindunji ndikutalikitsa moyo wautumiki wa gawo la throttle ndi kusindikiza pamwamba.
- Mpando wa valavu umatengera kusindikiza kosindikiza ndipo pachimake valavu ndi mpando umatenga kuwotcherera kwa Stellite alloy spray kuti valavu ikhale ndi kukana abrasion, kukana dzimbiri, anti-scouring ndi zina.
- Pakatikati pa valve imatenga masitepe atatu ochepetsera kuthamanga ndipo sitepe iliyonse ya throttle imayang'anira kuthamanga kwamadzimadzi pamwamba pa kuchepetsa kuthamanga kwambiri, kuteteza kuwonongeka kwa cavitation.
- Ndi njira yosinthika, actuator yoperekedwa ndi valavu imatha kukhazikitsidwa malinga ndi zofuna za ogwiritsa ntchito.
