Ukulawula i-valve yokudlula kwamanzi okuphambili
| Thayipha | Elawula Valve |
| Imodeli | I-T668Y-4500LB, T668Y-500, T668Y-630 |
| Ububanzi bokuqanjwa | I-DN 300-400 |
Isetshenziselwa ipayipi lokudlula lamanzi eliphambili le-boiler yeyunithi ye-1,000MW supercritical (ultra-supercritical) yokulawula ukugeleza kokugeleza kwamanzi.
- Ivelufa luqondile uhlobo lwesakhiwo, ukugeleza okuphakathi nendawo uhlobo lokugeleza nokubekwa uphawu kwesihlalo se-valve kukude nesinyathelo sokugcina se-flash evaporation zone ukuqinisekisa impilo yenkonzo.
- Umzimba we-valve nebhonethi yamukela isakhiwo sensimbi esakhiwe ngamandla amakhulu ukuhlangabezana kangcono nezidingo zamandla ngaphansi kokushisa okuphezulu nengcindezi.
- Yamukela isakhiwo sesihlalo se-valve esikhiphekayo futhi isihlalo se-valve sine-Welding eyakhiwe ngensimbi ye-6 ingxube ebusweni bayo bokuvala.
- Idiski ye-valve isebenzisa ukwakheka okulinganiselayo futhi uphawu lokuvala lubhekana nokuvama okukhulu kwemvamisa; izimbobo ezingenhla nezingezansi ze-valve disc ibona ibhalansi yengcindezi nge-pore yokuxhuma. Kulesi simo, i-valve ingavalwa ngedivayisi yokushayela engenawo amandla amancane.
- Ingxenye ye-throttle yomgogodla we-valve yakhelwe ukwamukela ingcindezi engqimba engu-6 ingcindezi yezinyathelo ezi-5 yokwehlisa isakhiwo ukusabalalisa uketshezi olulodwa olunamandla ngamandla amakhulu lube luketshezi olunemicu eminingi ngamandla aphansi ukunciphisa isivinini nomsindo. Ukwehliswa kwengcindezi yesinyathelo ngesinyathelo kutholakala ngokususwa kwesikhala ukuqeda i-cavitation. Umkhono wokugcina wesinyathelo wenza uketshezi lusuke luqonde ngakulayini oqondile futhi lubhekane nomgogodla ongaphakathi womzimba we-valve ngokungaqondile ukunciphisa ukushaywa komzimba we-valve.
- Uphawu flange Middle usebenzisa isakhiwo ezimbili-ukubekwa uphawu gasket izinyo gasket esiyinhlanganisela futhi nokunwebeka isitoreji amandla indandatho, okwenza ukubekwa uphawu ethembeke kakhudlwana.
- Ngaphansi kwesimo sokusebenza kokugeleza okuncane nokucindezela okukhulu kokuhlukaniswa, ukwamukelwa kwemikhono eminingi kwenziwa futhi kuncishiswe ukucindezelwa kwesinyathelo ngesinyathelo ngokuhlukaniswa kokuvulwa kwembobo enobubanzi obungalingani ukulawula isivinini sokugeleza okuphakathi ngokuqinile nokunciphisa umthelela i-cavitation nokuhwamuka kwe-flash ku-valve. Ngaphansi kwesimo sokusebenza kokugeleza okukhulu nengcindezi encane yokuhlukanisa, iwindi lesinyathelo esisodwa lamukelwa ukunciphisa ingcindezi ukuqinisekisa amandla okugeleza kwe-valve.
- Izici zomthethonqubo zithuthukiswa ngamaphesenti alinganayo, akwazi ukulawula ukuhamba okulingene ngokunembile ukuze kuzuzwe ukusebenza okuhle komthethonqubo.
- I-valve ingahlonywa ngemishini kagesi noma ye-pneumatic ozikhethela ngayo ukuvulwa nokuvalwa okusheshayo nokuvikelwa okuthathu.
