I-valve elawulayo ye-bypass enkulu yokuphakelwa kwamanzi
| Uhlobo | I-Valve elawulayo |
| Imodeli | T668Y-4500LB, T668Y-500, T668Y-630 |
| Ububanzi Okuzisholo | I-DN 300-400 |
Isetshenziselwa ipayipi elikhulu lokudlula amanzi elingu-1,000MW supercritical (ultra-supercritical) unit boiler ukuze lilawule ukugeleza kwamanzi.
- I-valve iyisakhiwo sohlobo oluqondile, isiqondiso sokugeleza okuphakathi siwuhlobo lokugeleza futhi indawo yokuvala yesihlalo se-valve ikude nesinyathelo sokugcina se-flash evaporation zone ukuze kuqinisekiswe impilo yesevisi.
- Umzimba we-valve nebhonethi zisebenzisa isakhiwo sensimbi efojiwe esinamandla aphezulu ukuhlangabezana kangcono nezidingo zamandla ngaphansi kwezinga lokushisa eliphezulu nokucindezela.
- Isebenzisa isakhiwo sesihlalo sevalvu esikhiphekayo futhi isihlalo sevalvu sine-Stellite No. 6 alloy build-up welding endaweni yaso yokuvala.
- I-valve disc ithatha isakhiwo esilinganiselayo futhi indawo yokuvala idlula ukucisha imvamisa ephezulu; imigodi engaphezulu nephansi ye-valve disc ibona ibhalansi yokucindezela ngembotshana exhumayo. Kulokhu, i-valve ingavalwa idivayisi yokushayela ene-thrust encane.
- Ingxenye ye-Throttle ye-valve core iklanyelwe ukusebenzisa isembozo se-6-ungqimba we-5-step sokunciphisa ukucindezela isakhiwo ukuze usakaze uketshezi olulodwa lwe-strand olunamandla aphezulu ku-multi-strand uketshezi olunamandla aphansi ukunciphisa isivinini nomsindo. Ukunciphisa ukucindezela kwesinyathelo ngesinyathelo kwenziwa ngokususwa kwe-aperture ukuze kuqedwe i-cavitation. Umkhono wesinyathelo sokugcina wenza uketshezi lusuke eduze komugqa we-tangent futhi lubhekane nomgodi ongaphakathi womzimba wevalvu ngokungaqondile ukuze kuncishiswe ukukhuhla emzimbeni wevalvu.
- Ukuvalwa kwe-flange emaphakathi kusebenzisa ukwakheka okumbaxambili kwe-wave tooth composite gasket kanye nendandatho yokugcina amandla enwebekayo, okwenza ukuvala kuthembeke kakhudlwana.
- Ngaphansi kwesimo sokusebenza sokugeleza okuncane kanye nokucindezela okukhulu komehluko, i-throttle ye-sleeve yezinyathelo eziningi iyamukelwa futhi ukuncishiswa kwengcindezi yesinyathelo ngesinyathelo kwenziwa ngokuhlelwa kokugudluka kwe-aperture enobubanzi obungalingani ukulawula isivinini sokugeleza okuphakathi ngokuqinile nokunciphisa umthelela i-cavitation kanye ne-flash evaporation ku-valve. Ngaphansi kwesimo sokusebenza sokugeleza okukhulu kanye nokucindezela okuncane okuhlukile, iwindi lesinyathelo esisodwa liyamukelwa ukunciphisa ingcindezi ukuze kuqinisekiswe umthamo wokugeleza we-valve.
- Izici zokulawula zithuthukiswa ngamaphesenti alinganayo, zikwazi ukulawula ukugeleza okuphakathi ngokunembile ukuze kuzuzwe ukusebenza okuhle kokulawula.
- I-valve ingafakwa ngogesi ozikhethela wona noma we-pneumatic ukuze ibone ukuvuleka nokuvala ngokushesha kanye nokuvikela okuthathu.
