Ivalve yokunciphisa uxinzelelo lwesikhululo sokunciphisa umsizi
| Uhlobo | I-Valve yokunciphisa uxinzelelo |
| Umzekelo | Y669Y-P58280V, Y669Y-3000SPL |
| Idayamitha yeNominal | DN 80 |
Isetyenziselwa inkqubo yokuvuthela umsizi we-600 ukuya kwi-1,000MW supercritical (i-ultra-supercritical) yeyunithi yebhoyila yamandla obushushu.
- Umzimba wevalve wamkela isakhiwo sentsimbi engumqili we-angular kunye namandla aphezulu kunye nesikhokelo sokuhamba okuphakathi luhlobo lokuvula lokuhamba ukuhlangabezana neemfuno zamandla phantsi kobushushu obuphezulu kunye noxinzelelo. Inokuwelda ngeempundu ngombhobho.
- Isihlalo sevalve sithatha isakhiwo esisuswayo ukuququzelela ukulungiswa kwesihlalo sevalve kunye nokutshintshwa.
- Umngxuma ombindi womzimba wevalvu wamkela ubume boxinzelelo lokuzitywina kwaye olo lwevalvu lunotywino olungcono emva kokuba lucinezelwe.
- Isihlalo sevalve sithatha ukutywinwa okucolisiweyo kunye nesiseko sevalve kunye nesitulo samkele iStellite alloy spray welding ukwenza ukuba ivalve ibe nokumelana ne-abrasion, ukumelana nokubola, ukuchasa kunye nezinye iimpawu.
- Idiskhi yevalve kunye nesiqu zinoyilo oludibeneyo, izibuko lenyathelo ngalinye lokugquma alikho kancinci kancinci elinobubanzi obungalinganiyo kunye nefitsha yokuqukuqela isilungiso esilingana nepesenti, ekwaziyo ukulawula ukuhamba komphunga ngokuchanekileyo ukufezekisa ukusebenza kakuhle kommiselo.
- I-valve core ithatha inyathelo eliqhubekayo le-sleeve ye-sleeve throttle pressure yokunciphisa isakhiwo. Umphunga udlula ngokuqhubekayo ukulawulwa ngamanyathelo amane kwi-sleeve kwaye inyathelo ngalinye lokunciphisa uxinzelelo lingaphezulu komlinganiselo wokunciphisa uxinzelelo, ukwenza ukungcangcazela kunye nengxolo ilawulwe ngokufanelekileyo.
- Ngokhetho oluguquguqukayo, i-actuator efakwe ivelufa inokumiselwa ngokweemfuno zabasebenzisi.
