Valavu yowongolera kupopera kwamadzi pazipita zothamanga kwambiri
| Mtundu | Valve yowongolera |
| Chitsanzo | Mtengo wa T761Y-2500LB, T761Y-420 |
| Nominal Diameter | DN 100-150 |
Imawongolera kutentha kumachepetsa kutentha kwa madzi ndi valavu yochepetsera kuthamanga kwa turbine yothamanga kwambiri. Ndi ntchito chikhalidwe cha kuthamanga kwambiri ndi kusiyana kwakukulu kuthamanga, izo utenga Mipikisano sitepe throttle akafuna kupewa kupezeka kwa cavitation ndi kung'anima evaporation.
- Vavu ndi mawonekedwe aang'ono ndipo njira yotuluka yapakati ndi mtundu wotsekera (yopingasa yolowera ndi pansi yotuluka).
- Kutengera kapangidwe kachitsulo kolimba kolimba kwambiri, thupi la vavu ndi boneti zimatha kukwaniritsa zofunikira pakutentha kwambiri komanso kupanikizika bwino.
- Ndi mawonekedwe amtundu wa manja a khola la masitepe ambiri, valavu yoyambira imazindikira masitepe angapo kuti muchepetse kuthamanga. Gawo lirilonse la throttle limapanga kukhudza kwamadzimadzi ndipo kutembenuka kwa 90 ° kumanja kumazindikira kuchepetsa kupanikizika. Popeza kupanikizika kuli pamwamba pa kuthamanga kwa machulukitsidwe pambuyo pa sitepe iliyonse ya kuchepetsa kuthamanga, palibe cavitation ndi evaporation ya flash yomwe imapangidwa panthawi yochepetsera kuthamanga; kugwedezeka ndi phokoso zimayendetsedwa bwino.
- Imatengera kapangidwe kachivundikiro kofananako kuti tipewe kutuluka kwamadzimadzi kuti zisapangitse mphamvu yopotoka papakati pa valve ndikupewa kukwapula m'mbali imodzi.
- Thupi la valve ndi boneti zimagwiritsa ntchito njira yodzisindikizira yokha.
- Pokhala ndi mawonekedwe oyenda pamlingo wofanana, imatha kuwongolera kuyenda kwapakati kuti ifikire magwiridwe antchito abwino molondola.
- Vavu ili ndi hydraulic actuator kuti izindikire kugwira ntchito mwachangu komanso kuwongolera.
