Valve yanjira zitatu ya Hydraulic yoperekera madzi otenthetsera kwambiri
| Mtundu | Valve yanjira zitatu |
| Chitsanzo | F763Y-2500LB, F763Y-320, F763Y-420 |
| Nominal Diameter | Mtengo wa DN 350-650 |
Pa ntchito yachibadwa ya 600 ku 1,000MW supercritical (ultra-supercritical) mphamvu yotentha yamagetsi, njira yaikulu ya valve ya njira zitatu pazitsulo zothamanga kwambiri imatsegulidwa ndipo njira yodutsa imatsekedwa. Madzi a boiler amalowa mu chotenthetsera chothamanga kwambiri kuchokera panjira yayikulu asanalowe mu boiler kudzera pa valve yanjira zitatu pamagetsi othamanga kwambiri.
- Thupi la valavu ndi boneti zimatengera kapangidwe kachitsulo kopangidwa bwino.
- Mtundu wosindikiza wa ma valve ndi boneti umagwiritsa ntchito njira yodzisindikizira yokha.
- Pamwamba pa boneti ya vavu muli jekeseni wa madzi ndi mabowo otulutsa madzi ndipo pisitoni imamangidwa mu boneti ya vavu.
- Kusindikiza pamwamba pa mpando wa valve ndi disc kutengera Stellite No. 6 alloy spray kuwotcherera.
- Kusindikiza kwa bypass kumatengera mawonekedwe osindikizira omwe amaphatikiza mphete yosinthika ya PTFE zotanuka komanso mphete ya perfluoro O-ring.
- Ma throttle elements mu inlet atatu valve bypass ndi mpando wapamwamba wa vavu amatengera mapangidwe ophatikizika ndipo safuna orifice yowonjezerapo padera.
