Kodi valavu yoyesera imagwira ntchito bwanji?

Ma valve owunikiraZingagwiritsidwenso ntchito pamizere yopereka machitidwe othandizira komwe kupanikizika kungakwere pamwamba pa kupsinjika kwa dongosolo. Ma valve owunikira amatha kugawidwa makamaka m'ma valve owunikira ozungulira (ozungulira malinga ndi pakati pa mphamvu yokoka) ndi ma valve owunikira okweza (oyenda motsatira mzere).
Cholinga cha valavu yamtunduwu ndikulola kuti cholumikizira chiziyenda mbali imodzi yokha ndikuletsa kuyenda mbali ina. Nthawi zambiri valavu yamtunduwu imagwira ntchito yokha. Pansi pa mphamvu ya madzi yomwe ikuyenda mbali imodzi, chivundikiro cha valavu chimatseguka; madzi akamayenda mbali ina, mphamvu ya madzi ndi chivundikiro cha valavu chomwe chimadzigwirizanitsa chokha cha chivundikiro cha valavu chimagwira ntchito pa mpando wa valavu, motero chimadula kuyenda.
Pakati pawo, valavu yowunikira ndi ya mtundu uwu wa valavu, womwe umaphatikizapovalavu yoyezera swingndi valavu yoyezera chikweza. Mavalavu oyezera chikweza ali ndi njira yolumikizira ma hinge ndi diski yofanana ndi chitseko yomwe imakhazikika momasuka pamwamba pa mpando wotsetsereka. Pofuna kuonetsetsa kuti diski ya valavu imatha kufika pamalo oyenera pamwamba pa mpando wa valavu nthawi zonse, diski ya valavu imapangidwa mu njira yolumikizira ma hinge, kotero kuti diski ya valavu ikhale ndi malo okwanira ozungulira ndipo imapangitsa diski ya valavu kukhudza bwino mpando wa valavu. Diskiyi ikhoza kupangidwa ndi chitsulo chokha, kapena yokutidwa ndi chikopa, rabara, kapena zophimba zopangidwa, kutengera zofunikira pakugwira ntchito. Mu mkhalidwe wotseguka kwathunthu wa valavu yoyezera chikweza, kuthamanga kwamadzimadzi kumakhala kosalephereka, kotero kutsika kwa kuthamanga kudutsa valavu ndi kochepa. Disk ya valavu yoyezera chikweza ili pamwamba pa mpando wa valavu pa thupi la valavu. Kupatula kuti diski ya valavu imatha kukwera ndikugwa momasuka, valavu yotsalayo ili ngati valavu yozungulira. Kuthamanga kwamadzimadzi kumakweza diski ya valavu kuchokera pamwamba pa mpando wa valavu, ndipo kuyenda kwa medium kumapangitsa diski ya valavu kubwerera ku mpando wa valavu ndikudula kuyenda. Malinga ndi momwe zinthu zilili, diski ikhoza kukhala yachitsulo chokha, kapena ikhoza kukhala ngati chogwirira cha rabara kapena mphete ya rabara yoyikidwa pa chogwirira cha diski. Monga valavu yozungulira, njira yamadzimadzi kudzera mu valavu yoyezera kukweza nayonso ndi yopapatiza, kotero kutsika kwa kuthamanga kudzera mu valavu yoyezera kukweza ndi kwakukulu kuposa kwa valavu yoyezera kugwedezeka, ndipo kuyenda kwa valavu yoyezera kugwedezeka kumakhala kochepa.
