Dukurikije ibikoresho byo gufunga hejuru,valve zo mu iremboishobora kugabanywamo ubwoko bubiri: ifunga rikomeye n'ifunga ryoroshye. Ni irihe tandukaniro riri hagati ya valve yoroshye n'ifunga rikomeye:
Valve ikomeye yo gushyiramo agakingirizo: Ibikoresho byo gufunga ku buso bwombi bwo gufunga ni ibikoresho by'icyuma, byitwa "agakingirizo gakomeye". Ubudahangarwa n'ubushyuhe bwinshi, kudasaza, imiterere myiza ya mekanike nka: icyuma + icyuma; icyuma + umuringa; icyuma
+ Graphite; icyuma + icyuma cy'aluminiyumu. Ibikoresho bikunze gukoreshwa mu gufunga ni: icyuma cya 13Cr kitagira umugese, ibikoresho bikomeye by'aluminiyumu, karubide ya tungsten iterwa, nibindi. Ubuso bwo gufunga ntibufunze neza.
Valve yoroshye yo gushyiramo agace k'inyuma: agace k'inyuma gakozwe mu byuma ku ruhande rumwe n'ibikoresho bidafite icyuma birenduka ku rundi ruhande, byitwa "agace k'inyuma". Uburyo bwo gufunga bw'ubu bwoko bw'agace k'inyuma ni bwiza, ariko ntirwanya ubushyuhe bwinshi, byoroshye kwambara, kandi bifite imiterere mibi ya mekanike. Nk'icyuma + rubber; icyuma + PTFE, nibindi. Bivuze ko uruhande rumwe rw'agace k'inyuma rukozwe mu bikoresho bifite ubukana buke. Muri rusange, intebe y'inyuma yoroshye ikozwe mu bikoresho bitari ibyuma bifite imbaraga runaka, ubukana n'ubushyuhe. Ifite ubushobozi bwo gufunga neza kandi ishobora kugera ku gusohoka nta cyuho, ariko imara igihe kirekire. Ugereranyije n'uburyo budashobora kwihuza n'ubushyuhe, agace k'inyuma gakozwe mu cyuma, kandi ubushobozi bwo gufunga nta cyuho ni bubi, nubwo bamwe mu bakora bavuga ko gashobora kugera ku gusohoka nta cyuho. Intego yo kuvumbura valve yoroshye yo gufunga: gukemura ikibazo cy'intebe ya valve n'ubuso bwo gufunga bwa plate ya valve bwangiritse cyangwa bwangiritse, plate ya valve ishobora kwishyura igipfukisho gifunga umuvuduko n'uburyo umuvuduko ugenda wiyongera hamwe na valve yoroshye yo gufunga umuvuduko, no gukemura ikibazo cy'ibikoresho byoroshye byo gufunga byangiritse bitewe no gukururana. Ikibazo cy'ubuso bwo gufunga, kuko agakoresho ko gufunga ka valve y'irembo gashobora gusimburwa, bikongera cyane ikoreshwa rya valve.
Uburyo bworoshye bwo gukoresha valve yoroshye yo gufunga: umurambararo (p50-p400mm, igitutu 2.5-4.0MPa, ibinyabutabire bitandukanye bisanzwe biri munsi ya 200℃).
Ifu yoroshye ntishobora kuzuza ibisabwa ku bikoresho bimwe na bimwe byangiza, kandi ifu ikomeye irashobora kuyikemura!
Ubwo bwoko bubiri bw'udupfundikizo burashobora kuzuzanya. Ku bijyanye no gukomera, agapfundikizo koroshye ni keza, ariko ubu gukomera kwa gapfundikizo gakomeye na ko gushobora kuzuza ibisabwa bihuye! Akamaro k'agapfundikizo koroshye ni imikorere myiza yo gupfundikizo, ariko ikibi ni uko byoroshye gusaza, kwangirika, kandi kamara igihe gito. Agapfundikizo gakomeye kamara igihe kirekire, ariko gukomera kwako ni kubi kurusha agapfundikizo koroshye.
