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. Icyicaro cyibinyugunyugu ni kinini 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. Ubushyuhe, ubushyuhe bwo hasi burashobora kuba -40 ° C - 60 ° C, burashobora 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 yagaragaye, ikemura neza inganda zimiti, peteroli, imiti nizindi nganda mubibazo byinshi.
4. 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 i kumeneka.
