Gufungura-inkoni / umwijima-inkoni nodular ikozwe mucyuma flange irembo ni ubwoko bwibikoresho bya nodular bikozwe mucyuma bikozwe mu cyuma cya flange, gifite imbaraga nyinshi, kwambara birwanya kandi bikora neza. Ubu bwoko bwa valve bukoreshwa cyane mubikoresho bitandukanye byubwubatsi, peteroli, inganda zikora imiti, gutunganya amazi nizindi nzego kugirango bigerweho, kuzenguruka no kugenzura itangazamakuru ryimiyoboro.
Gufungura inkoni / umwijima wijimye wicyuma flange amarembo arimo DN250, DN300, DN400, DN500, DN600, DN700, DN800 na DN900 nubundi bunini kugirango uhuze ibyifuzo bitandukanye. Uburyo bwo guhuza bwa valve ni flange ihuza, byoroshye gushiraho no kubungabunga.
Gufungura inkoni hamwe ninkoni yijimye nuburyo bubiri bwo gukora bwa nodular cast Iron flange gate valve. Gufungura inkoni isobanura ko gufungura no gufunga bya valve bikora ku buryo butaziguye ku gikoresho cya valve binyuze mu ruziga rw'intoki, kandi imikorere ni intiti kandi yoroshye. Imikorere yinkoni ihishe ni uguhinduranya kuzenguruka kwintoki zinyuze mumababi ya valve mumurongo ugororotse ugana uruti rwa valve, kugirango valve ifungurwe cyangwa ifunze. Imikorere yinkoni yijimye irahagaze neza kuruta gufungura inkoni, ikwiranye numuvuduko mwinshi, nini nini ya diameter.
Muri rusange, fungura inkoni / inkoni yijimye ductile ibyuma bya flange irembo hamwe nibikoresho byiza byayo hamwe nubunini butandukanye, bikoreshwa cyane mubikorwa byose, kubikorwa byizewe kandi byizewe bya sisitemu y'imiyoboro itanga garanti ikomeye.
