Valavu yochepetsera mphamvu yochepetsera mwaye
| Mtundu | Valve Yochepetsa Kupanikizika |
| Chitsanzo | Y669Y-P58280V, Y669Y-3000SPL |
| Nominal Diameter | Chithunzi cha DN80 |
Amagwiritsidwa ntchito powomba mwaye wa 600 mpaka 1,000MW supercritical (ultra-supercritical) matenthedwe amagetsi amagetsi.
- The valavu thupi utenga angular forged zitsulo kapangidwe ndi mphamvu mkulu ndi sing'anga otaya njira ndi otaya otsegula mtundu kukwaniritsa zofunika mphamvu pansi pa kutentha ndi kupanikizika. Ili ndi kuwotcherera matako ndi chitoliro.
- Mpando wa valavu umatenga mawonekedwe ochotsedwa kuti athandizire kukonza ndikusintha mipando ya valve.
- Pakatikati pa thupi la valavu imagwiritsa ntchito makina odzisindikizira okha ndipo ya valve imakhala ndi chisindikizo chabwino ikakanikizidwa.
- 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.
- Vavu chimbale ndi tsinde ndi Integrated kamangidwe, doko la sitepe iliyonse chivundikirocho si pang'onopang'ono kabowo ndi m'mimba mwake wosafanana ndi otaya mbali ndi kukonzedwa ofanana peresenti, angathe kulamulira nthunzi kuyenda molondola kukwaniritsa bwino malamulo ntchito.
- Pachimake valavu amatengera mosalekeza masitepe anayi manja throttle kuthamanga kuchepetsa dongosolo. Mpweya umadutsa mumkono wokhazikika wa masitepe anayi m'manja ndipo gawo lililonse la kuchepetsa kupanikizika kumakhala pamwamba pa kuchepetsa kupanikizika, kumapangitsa kugwedezeka ndi phokoso kuyendetsedwa bwino.
- Ndi njira yosinthika, actuator yoperekedwa ndi valavu imatha kukhazikitsidwa malinga ndi zofuna za ogwiritsa ntchito.
