Kukhetsa valavu kwa steam-water system
| Mtundu | Valve yotsitsa |
| Chitsanzo | PJ661Y-500(I) V, PJ661Y-630 V, PJ661Y-P54290(I) V, PJ661Y-P61310 V |
| Nominal Diameter | DN 40-100 |
Chogulitsacho chimagwiritsidwa ntchito popangira madzi a nthunzi ya boiler kapena turbine yamagetsi yamatenthedwe amphamvu kwambiri (ultra-supercritical) unit.
- Thupi la valavu limagwiritsa ntchito kapangidwe kake konse.
- Mtundu wosindikiza wa ma valve ndi boneti umagwiritsa ntchito njira yodzisindikizira yokha.
- Kusindikiza pamwamba pa mpando wa valve kuli ndi Stellite 6 alloy build-up welding.
- Kusindikiza pamwamba pa chimbale cha valve kumakhala ndi kuwotcherera kwa Stellite 12 alloy build-up.
- Ndi m'mphepete (kapena annular pressure reduction groove) kutsogolo kwake, malo osindikizira amatha kuteteza tinthu tating'onoting'ono ndi zonyansa zamapaipi kuti zisaphwanye malo osindikizira akatseka ma valve.
- Gawo losindikiza limagwiritsa ntchito masitepe awiri a throttle element kuchepetsa kapangidwe kake komanso kupanikizika kwapakatikati kumachepetsa pang'onopang'ono kuteteza cavitation ndi scouring kuti zisawononge malo osindikizira.
