Intebe y'agatebe k'ikinyugunyuguni igice gishobora gukurwamo imbere muri valve, inshingano nyamukuru ni ugushyigikira plate ya valve ifunguye cyangwa ifunze neza, kandi ikaba ari vise yo gufunga. Ubusanzwe, umurambararo w'intebe ni ingano ya caliber ya valve. Ibikoresho by'intebe ya valve ya Butterfly ni binini cyane, ibikoresho bikunze gukoreshwa ni EPDM yoroshye yo gufunga, NBR, PTFE, n'ibikoresho bya carbide ikomeye yo gufunga by'icyuma. Ubutaha tuzabagezaho kimwe kimwe.
1.EPDM-Ugereranyije n'izindi rubber zikoreshwa muri rusange, rubber ya EPDM ifite ibyiza byinshi, bigaragarira cyane cyane muri:
A. Ihendutse cyane, mu bitoki bikunze gukoreshwa, agapfunyika ka EPDM ni koroshye cyane, ushobora kuzuza byinshi, ukagabanya ikiguzi cya kabutura.
B. Ubudasaza bw'ibikoresho bya EPDM, burwanya izuba, ubushyuhe, ubushyuhe bw'amazi, burwanya imirasire, bukwiriye aside nke na alkali, bufite ubushobozi bwiza bwo gukingira.
C. Ingano y'ubushyuhe, hasi cyane ishobora kuba -40 ° C - 60 ° C, ishobora kuba imiterere y'ubushyuhe bwa 130 ° C kugira ngo ikoreshwe igihe kirekire.
2. Amavuta ya NBR arwanya ubushyuhe, arwanya kwangirika, arwanya amazi kandi icyarimwe arwanya amazi, afunga umwuka kandi afite ubushobozi bwiza bwo gufatana. Ikoreshwa ryinshi mu miyoboro ya peteroli, ikibazo ni uko idahangana n'ubushyuhe buke, irwanya ozone, ubushobozi buke bwo gukingira, kandi ubushyuhe bwayo ni rusange.
3. PTFE: pulasitiki ya fluorine, iyi pulasitiki ifite ubushobozi bwo kurwanya aside na alkali, ishobora kurwanya aside na alkali mu buryo butandukanye, mu gihe imiterere yayo irwanya ubushyuhe bwinshi, ishobora gukoreshwa buri gihe kuri 260 ℃, ubushyuhe bwo hejuru bushobora kugera kuri 290-320 ℃, PTFE yagaragaye, yakemuye neza inganda z'imiti, peteroli, imiti n'izindi nganda mu bibazo byinshi.
4. Ifunze ry'icyuma (carbide): Ifunze ry'icyuma rirwanya ubushyuhe bwinshi n'umuvuduko mwinshi, rirwanya ingese, rirwanya kwangirika, ni ryiza cyane mu kwishyura inenge z'ifunze ryoroheje ntirirwanya ubushyuhe bwinshi n'umuvuduko mwinshi, ariko ifunze ry'icyuma rirwanya ibikenewe mu gutunganya ni rinini cyane, ikibazo cyonyine cy'imikorere yo gufunga icyuma gikingira ni kibi, kizaba nyuma y'igihe kirekire nyuma y'akazi k'ifunze.
