I-valve yokulawula amanzi yaseChinasebenzisa izinyathelo zokuphepha: isinyathelo esibalulekile sokusebenza okuphephile
I-valve yokulawula amanzi yaseChina iyithuluzi elivamile lokulawula uketshezi, elisetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni. Kodwa-ke, uma ukusebenza kungalungile noma kungaphephile, kungabangela ukulimala kumshini futhi kubangele nezingozi zokuphepha. Ngakho-ke, kubalulekile ukuqonda nokuhambisana nezinyathelo zokuphepha zokusetshenziswa kwamavalvu okulawula amanzi e-China. Lesi sihloko sizokunikeza izinyathelo zokuphepha ezibalulekile ngokombono wochwepheshe.
