Pressure yekudzikisa vharafu yekufuridza soot yekudzikisa chiteshi chemhepo pre-heater
| Type | Kudzvinyirira Kuderedza Valve |
| Model | Y666Y-P55 80Ⅰ, Y666Y-1500LB |
| Nominal Diameter | DN 100 |
Iyo soot inofuridza yekudzikisa vharafu ye600 kusvika 1,000MW supercritical (ultra-supercritical) air pre-heater inotora tembiricha yekudziisazve chitsinga semhepo inovhuvhuta soot. Kudzvanya kunoderedzwa nevhavhavha yekudzora soot inofuridza yekudzikisa chiteshi uye inopihwa kune soot blower semhepo inovhuvhuta soot.
- Muviri wevharuvhu unotora yakaumbwa welding chimiro nesimba rakakura uye vharafu ine simba rakakwana. Iine "Z" chimiro chemhando, ine butt welding ine pombi.
- Iine yunifomu yekuyerera chivharo, iyo yevhavha inopinza inoita yepakati kuyerera kubva kuperiphery kuenda kune iyo throttle chikamu zvakaenzana kudzivirira yepakati kubva pakutsvaira chikamu chemukati uye chisimbiso pamusoro peiyo throttle zvakananga uye kurebesa hupenyu hwesevhisi ye throttle chikamu uye chisimbiso chepamusoro.
- Chigaro chevharuvhu chinotora conical chisimbiso uye simbi yevharuvhu uye chigaro inotora Stellite alloy spray welding kuita kuti vharafu ive neabrasion resistance, corrosion resistance, anti-scouring uye humwe hunhu.
- Iyo yevhavha yepakati inotora matatu-nhanho throttle pressure kuderedza uye nhanho imwe neimwe ye throttle inodzora kuyerera kwemvura pamusoro peyakanyanya kudzvinyirira kudzikisa ratio, kudzivirira kukuvara kwecavitation.
- Iine inoshanduka sarudzo, iyo actuator inopihwa nevhavha inogona kugadzirwa sekuenderana nezvinodiwa nevashandisi.
