Kubera ko ntigeze nitondera cyane valve ihinduranya muruganda ruvanga asfalt mbere, sinabishoboye kubijyanye no kunanirwa kwiki gikoresho. Mubyukuri, kunanirwa kwinyuma ya valve ntabwo bigoye cyane. Igihe cyose uzi bike kubijyanye, uzamenya byanze bikunze kubyitwaramo?
Hariho kandi gusubira inyuma mumashanyarazi avanze na asfalt, kandi kunanirwa kwayo ntakindi kirenze ibibazo bisanzwe nko guhindukira bidatinze, kumeneka gaze, hamwe na valve ya electronique. Nibyo, ibitera nibisubizo bihuye nibibazo bitandukanye bigaragara nabyo biratandukanye. Kubintu byo guhindukira bidatinze mugihe cyo gusubira inyuma, inyinshi murizo ziterwa no gusiga nabi kwa valve, amasoko yangiritse cyangwa yangiritse, amavuta cyangwa umwanda wafashwe mubice byanyerera, nibindi. Kubwibyo, birakenewe kugenzura uko leta ihagaze igikoresho cyamavuta hamwe nubwiza bwamavuta yo gusiga. Niba hari ikibazo, amavuta yo gusiga cyangwa ibindi bice birashobora gusimburwa. Nyuma y’uruganda ruvanze na asfalt rumaze igihe kinini rukora, indege yacyo isubira inyuma ikunda kwambara impeta ya kashe ya kashe, kwangirika kwuruti rwa valve hamwe nintebe ya valve, bigatuma imyuka isohoka muri valve. Muri iki gihe, inzira nziza kandi ifatika yo guhangana nayo ni ugusimbuza impeta ya kashe, igiti cya valve hamwe nintebe ya valve, cyangwa gusimbuza byimazeyo guhinduranya kugirango utsinde ikibazo cyo kumeneka.
