I-valve yokulawula ukukhishwa okuphuthumayo ye-heater enomfutho ophezulu
| Uhlobo | Ivalve yesango |
| Imodeli | Z964Y |
| Ingcindezi | I-PN20-50MPa 1500LB-2500LB |
| Ububanzi Okuzisholo | I-DN 300-500 |
Isetshenziswa njengamadivaysi okuvula nawokuvala ohlelo lokumpompa noma ezinye izinhlelo zamapayipi omfutho ophakathi nendawo wama-600 kuya ku-1,000MW supercritical (ultra-supercritical) unit steam turbine.
- Umzimba we-valve nebhonethi zisebenzisa uhlaka oluphakathi nendawo olunebhawudi ye-flange, ehlanganisa ukuqaqa okulula. Zombili iziphetho zisebenzisa uxhumano oluhlanganisiwe.
- I-valve disc isebenzisa isakhiwo sekhava esinezinyathelo eziningi zokuphakamisa uhlobo.
- Isihlalo se-valve sithatha ukuvaleka kwe-conical. Nge-alloy build-up welding eqinile, indawo yokubeka uphawu ifaka i-cavitation kanye nokumelana nemihuzuko.
- Isembozo sezinyathelo eziningi samukelwa ukulawula isinyathelo ngasinye sokwehla kwengcindezi ukwenza ukulawula kwengcindezi ye-throttled ngaphezu kwengcindezi yokugcwala ukuze kuncishiswe ukuvela kwe-cavitation kanye nokuhwamuka kwe-flash.
- Ngenketho eguquguqukayo, i-actuator enikezwe i-valve ingacushwa ngokwezidingo zabasebenzisi.
