Ivalve ligama eliqhelekileyo lamalungu olawulo athi aphambuke, anqunyulwe kwaye alawule ulwelo
Imbali yoshishino lwevalvu
Ukulandela umva kwimvelaphi yevalvu, kufuneka ilandwe umva kwinto eyenziwe ngomthi kumabhodlo amandulo aseYiphutha awayecingelwa ukuba sisivalo ngo-1000 AD.Ngexesha lamaRoma amandulo, kwakusele kukho izibonelelo zemibhobho kumakhaya abantu abahloniphekileyo kunye neevalvu zobhedu ezithunyelwa ngaphandle.
Kamva, iteknoloji yevalve nayo yaphuculwa.Ngokuphuculwa kobugcisa bemveliso yeevalvu zentsimbi, iindlela ezintsha zokuphosa nazo zamkelwa kwaye izinto zaphuculwa.Ivalve yentsimbi ithatha oomatshini abasebenzayo abanamandla, kwaye ukuchaneka kuye kwaphuculwa.
Ukujongana nokunqongophala kwamanzi kwimibhobho yokwakha, imimiselo yengxolo enxulumene nezibonelelo zemveliso, kunye nokwandiswa kokhuseleko lwegesi, iivalvu zibandakanya iivalvu ezichasa ukubola kwimibhobho yonikezelo lwamanzi, iivalvu eziphantsi-ingxolo yokunciphisa ingxolo yokuhamba, iimpompo zesokhethi, kunye ukudibanisa.Ukuguqulwa kweeplagi zegesi yesilika.
Ngoku siqalisileoomatshini bevalve ekhethekileyokwayeumatshini wokulungisa ivalvuenokukwenza oku.Emva kophuculo oluninzi, isixhobo sangoku sokusika isixhobo sifikelela kwi-10mm.Isebenza kakuhle, ifanelekile, izinzile kwaye inokwethenjelwa.Inikezelwe ekusetyenzweni kwentsimbi ebunjiweyo, intsimbi etyhidiweyo, iivalvu zesango, iivalvu zeglowubhu, iivalvu zebhabhathane, iingqiniba, njl.
