Tonsefe tikudziwa kufunika kwa tayala pa galimoto, koma kodi mumadziwa kuti tayala laling'onovalavu ya tayalaKodi imagwiranso ntchito yofunika kwambiri?
Ntchito ya valavu ndi kupopera ndi kumasula gawo laling'ono la tayala ndikusunga chitsekocho tayala litadzaza mpweya. Vavu wamba imapangidwa ndi zigawo zitatu zazikulu: thupi la valavu, pakati pa valavu ndi chivundikiro cha valavu. Pansipa tikupatsani chidziwitso chatsatanetsatane cha valavu ya tayala la galimoto.
1. Yogawidwa ndi cholinga: valavu ya njinga, njinga yamoto, valavu ya galimoto yamagetsi, valavu ya galimoto, valavu ya basi ya galimoto, valavu ya galimoto ya uinjiniya wa zaulimi, valavu yapadera, ndi zina zotero.
2. Malinga ndi ngati pali chubu kapena ayi: valavu ya chubu ya valve ndi valavu yopanda chubu yopanda valve.
3. Malinga ndi njira yosonkhanitsira: valavu yolumikizira screw-on,Valavu yolumikizirandivalavu yolowera mkati.
4. Malinga ndi kukula kwa pakatikati pa chivundikiro: valavu wamba wa chipinda chapakati ndi valavu yayikulu ya chipinda chapakati.
Thupi la valavu (maziko) ndiyo njira yokhayo yomwe mpweya umalowera mu tayala, ndipo nthawi yomweyo umasunga ndikuteteza pakati pa valavu; nati yomangira imadziwika kuchokera ku dzinalo ndipo ntchito yake ndikupangitsa valavu ndi mkombero kukhala zokhazikika; ziwiri. Ma gasket azinthu zosiyanasiyana amafanana ndi nati yomangira; gasket yomangira rabara imagwira ntchito yotseka ndikuletsa kutuluka kwa mpweya mkati mwa mkombero; chivundikiro cha valavu chomwe nthawi zambiri chimatayika chingalepheretse kuukira kwa valavu ndi zinthu zakunja, komanso nthawi yomweyo kukwaniritsa kutseka kwachiwiri kwa valavu; ndipo pakati pa valavu pali ntchito yoletsa mpweya kutuluka pamene ikuwonetsetsa kuti mpweya ukulowa bwino mu tayala.
Njira zosonkhanitsira ma valavu zitha kugawidwa m'magulu awiri: mtundu wa screw-on, mtundu wa compression ndi mtundu wa snap-on. Mwachitsanzo, clamp ya valavu ya rabara ndi mtundu wa snap-in, ndipo maziko a valavu amaperekedwa ndi malo okonzera ndi rim, zomwe zimapangitsanso kuti igwiritsidwe ntchito kamodzi kokha, ndipo ikachotsedwa, singagwiritsidwenso ntchito. Vavu yachitsulo imagwiritsa ntchito screw-on assembly, yomwe imagwiritsa ntchito ma gasket ndi ma fastening nuts kuti ikonze valavu, ndipo imatha kugwiritsidwanso ntchito ikachotsedwa.
