FDO4-BV1-3L (High ukusebenza butterfly valve)
Kafushane
Inezici ezinhle zokushisa nokubandayo, futhi ubukhulu be-valve buhambisana nobubanzi bepayipi, futhi bunganciphisa ngempumelelo ukulahleka kokushisa okuphakathi kwepayipi. Ukuze uhambise okuphakathi kwe-viscosity okuzoqina ekamelweni lokushisa. Ngokwesakhiwo esihlukile se-valve, sisetshenziswa kakhulu kupayipi lesistimu lokwakhiwa kwamadolobha, imboni yamakhemikhali, insimbi, uphethiloli, okwenziwa ngemithi, ukudla, isiphuzo, ukuvikelwa kwemvelo nezinye izimboni.
Amazinga
1. Uhlobo olusebenzayo oluhlelekile lokusika. Ingasetshenziswa njenge-valve elawula i-valve kanye ne-valve yokuvala.
2. Uhlobo lokuvalwa kwezindlela ezimbili, oluhlukile ekubekweni uphawu kwendlela eyodwa, lungavalwa ngokuthembekile noma ngabe kwenzeka ukuhlehlela emuva okuphakathi noma into ethi "isando somoya".
3. Umzimba we-valve usebenzisa ubuchwepheshe bokuqopha obudingekayo ngesakhiwo esihlangene, ivolumu encane nesisindo esincane;
4. Kwakheka ukwakheka okumbili okwehlukile. Lapho uvala, ipuleti le-valve linwebela ngaphandle ukufeza isimo sokuvala uphawu esihle kakhulu; lapho kuvulwa, ipuleti le-valve kanye nendandatho yokufaka uphawu ihlukaniswa ngokushesha ukuvimbela ngempumelelo ukugqoka kwendandatho yokufaka uphawu. Ngale ndlela, i-torque yokusebenza iyancipha futhi impilo yokusebenza kwe-valve iyakhuphuka.
5. Indandatho yophawu inoveli ekwakhiweni futhi isebenzisa ubuchwepheshe obusezingeni eliphakeme emhlabeni: uphawu lwe-PTFE lwamukela isakhiwo "sezinyo lezindebe"; uphawu oluqinile lusebenzisa uphawu lwe-"U" lokuqina okunwebeka. Impilo yesevisi yesakhiwo sokubekwa uphawu yinde futhi inokwethenjelwa. Ngokuqondene nemibandela yothayi oluthambile nophawu oluqinile, kuncike kakhulu kuzidingo zomsebenzisi, izimo zesevisi kanye nezidingo zokulwa nokugqwala.
