Ingcaciso yeMveliso
Le mveliso yivalvu yebhola eqinileyo yentsimbi eqinisiweyo, esetyenziswa kakhulu kwiinkqubo zemibhobho yemizi-mveliso enoxinzelelo oluphezulu, ubushushu obuphezulu kunye neemeko zokusebenza ezinzima. Umzimba wevalvu kunye neendawo eziphambili ezithwele uxinzelelo zenziwe ngentsimbi eqinisiweyo, exineneyo ngezinto kwaye izinzile ngamandla, ifanelekile ukusebenza ixesha elide phantsi kweemeko zokusebenza.
Ibhola yevalvu kunye nesihlalo sevalvu sisebenzisa uhlobo lokutywina oluvela kwisinyithi ukuya kwisinyithi, olunokusetyenziswa kwiindawo zobushushu obuphezulu, kwiindawo zokushicilela ezineenxalenye, okanye kwiimeko ezinemingcipheko yokuguguleka. Phantsi kwezi meko zingasentla, xa kuthelekiswa nezakhiwo zokuvala ezithambileyo, ukuthembeka kokutywina kuzinzile ngakumbi.
Ivalvu isebenzisa isakhiwo sokuvula nokuvala esijikelezayo esingama-90°. Ngokuxhomekeke kububanzi kunye nomlinganiselo woxinzelelo, inokuxhotyiswa ngebhola edadayo okanye isakhiwo sebhola esizinzileyo. Isakhiwo sebhola esizinzileyo sixhaswa ziibheringi eziphezulu nezisezantsi ukuze zithwale uxinzelelo oluphakathi, olunokunciphisa amandla kwisiqu sevalvu kwaye lufanelekile kumanqanaba aphezulu oxinzelelo okanye ububanzi obukhulu.
Umphezulu wokutywina ungasetyenziselwa ukuwelda okanye ukuqinisa umphezulu ngokweemeko zokwenyani zokuphucula ukumelana nokuguguleka kunye nobomi benkonzo.
Izinto ezisetyenziswa kwivalvu, uhlobo loqhagamshelwano kunye nendlela yokusebenza zinokucwangciswa ngokweemeko zokusebenza okanye iimfuno zemizobo.
