Gupakira ibishyimbo bya kawa ntabwo bishimishije gusa, ahubwo birakora.Gupakira neza birashobora guhagarika neza ogisijeni kandi bigabanya umuvuduko wa kawa ibishyimbo bibi.
Imifuka myinshi yikawa yibishyimbo izaba ifite uruziga, rumeze nka buto kuriyo.Kata igikapu, kandi impumuro ya kawa izacukurwa mu mwobo muto uri hejuru ya "buto".Iyi "buto" ishusho ntoya yitwa "inzira imwe yo gusohora valve".
Ibishyimbo bya kawa bikaranze bishya birekura buhoro buhoro karuboni ya dioxyde de carbone, kandi uko umwijima wijimye, niko imyuka ya gaze karuboni irekurwa.
Hariho imikorere itatu ya valve yumuhanda umwe: icya mbere, ifasha ibishyimbo bya kawa kunanirwa, kandi mugihe kimwe ikarinda okiside yibishyimbo bya kawa biterwa no gusubira inyuma kwumwuka.Icya kabiri, mugihe cyo gutwara abantu, irinde cyangwa ugabanye ibyago byo gupakira byatewe no kwaguka kwumufuka kubera umunaniro wibishyimbo bya kawa.Icya gatatu, kubaguzi bamwe bakunda kunuka impumuro nziza, barashobora kubona impumuro ishimishije yibishyimbo bya kawa mbere bakanda igikapu cyibishyimbo.
Ese imifuka idafite valve yinzira imwe yujuje ibyangombwa?Ntabwo rwose.Bitewe nurwego rwo kotsa ibishyimbo bya kawa, imyuka ya karuboni nayo iratandukanye.
Ibishyimbo byikawa byijimye bikaranze imyuka myinshi ya gaze karuboni, bityo rero harasabwa valve yumuhanda umwe kugirango ifashe gaze guhunga.Kubishyimbo bya kawa byoroheje byokeje, imyuka ya gaze karuboni ntabwo ikora cyane, kandi kuba hari valve yumuhanda umwe ntabwo ari ngombwa.Niyo mpamvu, mugihe ukora ikawa yuzuye, ikariso yoroheje iba "nini" kuruta ibishyimbo byokeje.
Usibye inzira imwe yo gusohora valve, ikindi gipimo cyo gupima paki nibikoresho byimbere.Gupakira neza, igipande cyimbere ni aluminiyumu.Ifu ya aluminiyumu irashobora guhagarika neza ogisijeni, urumuri rwizuba nubushuhe hanze, bigatera ahantu hijimye kubishyimbo bya kawa.
