Ukubonisa umlingani
Izinsiza zekhanda lomthombo womjovo wamanzi zisetshenziswa ikakhulukazi emisebenzini yokujova amanzi ukulawula ukugeleza kanye nomfutho woketshezi. Izici zazo ezibalulekile zihlanganisa ikhono lokwenza hhayi kuphela ukujova amanzi okuqondile nokubuyela emuva, kodwa futhi nokugeza umthombo ngomjovo oqondile nokubuyela emuva, ukuhlolwa komjovo wamanzi, neminye imisebenzi.
Izinsiza zekhanda lomjovo wamanzi zitholakala ngezinhlaka ezinhlanu ezihlukene: iqembu lamavalvu amane, amavalvu amahlanu, amavalvu ayisithupha, amavalvu ayisikhombisa, namavalvu ayisishiyagalombili. Konke ukuxhumana kusebenzisa izixhumi zohlobo lwe-clamp, okuholela osayizi abancane, isisindo esilula, kanye nokuhlanganiswa nokuhlakazwa okulula. Wonke amavalvu angamavalvu esango ohlobo lwe-wedge.
