Icyicaro cy'ikinyugunyuguni igice cyimurwa imbere muri valve, uruhare nyamukuru nugushyigikira icyapa cya valve gifunguye cyangwa gifunze byuzuye, kandi kigizwe na kashe.Mubisanzwe, diameter yintebe nubunini bwa kalibiri.Ibikoresho by'ikinyugunyugu ni binini cyane, ibikoresho bikoreshwa ni byoroshye gufunga EPDM, NBR, PTFE, hamwe nicyuma gikomeye gifunga karbide.Ubutaha tuzamenyekanisha umwe umwe.
1.EPDM-Ugereranije nizindi ntego rusange-reberi, reberi ya EPDM ifite ibyiza byinshi, bigaragarira cyane muri:
A. Birahenze cyane, mubitoki bikunze gukoreshwa, kashe ya reberi mbisi ya EPDM niyo yoroshye, urashobora gukora byinshi byuzuye, ukagabanya igiciro cya reberi.
B. Ibikoresho bya EPDM birwanya gusaza, kwihanganira izuba, kurwanya ubushyuhe, kurwanya imyuka y'amazi, kurwanya imirasire, bikwiranye na acide nkeya hamwe nibitangazamakuru bya alkali, ibintu byiza byo kubika.
C. Ikirere cy'ubushyuhe, hasi cyane gishobora kuba -40 ° C - 60 ° C, gishobora kuba 130 ° C ubushyuhe bwo gukoresha igihe kirekire.
2.NBR-yamavuta irwanya, irwanya ubushyuhe, irwanya kwambara kandi mugihe kimwe ifite amazi meza yo kurwanya amazi, gufunga ikirere hamwe nuburyo bwiza bwo guhuza.Ibisabwa byinshi mumuyoboro wa peteroli, ibibi ni uko idashobora guhangana nubushyuhe buke, kurwanya ozone, imiterere idahwitse, elastique nayo ni rusange.
3. PTFE: plastike ya fluor, ibi bikoresho bifite imbaraga zo kurwanya aside na alkali, kang imikorere itandukanye yumuti ukomoka kumubiri, mugihe ibikoresho birwanya ubushyuhe bwinshi, birashobora gukoreshwa ubudahwema kuri 260 ℃, ubushyuhe bwo hejuru burashobora kugera kuri 290-320 ℃ , PTFE yagaragaye, ikemura neza inganda zimiti, peteroli, imiti nizindi nganda mubibazo byinshi.
4. Ikidodo gikomeye (karbide): icyuma gikomeye cya kashe ya valve icyicaro gifite imbaraga zo guhangana nubushyuhe bwo hejuru hamwe n’umuvuduko mwinshi, kurwanya ruswa, kwambara biranga kwihanganira, nibyiza cyane kugirango usubize inenge yibikoresho byoroheje bifunze ntibishobora kwihanganira ubushyuhe bwinshi hamwe n’umuvuduko mwinshi, ariko ibikoresho bikomeye bya kashe kubisabwa kugirango bishoboke gutunganywa ni byinshi cyane, ibibi byonyine byicyuma gikomeye cya kashe ya valve intebe yo gufunga imikorere ni mibi, bizaba mugihe kirekire nyuma yimikorere yimirimo ya kumeneka.
