Ku rakibida Check Valve
Waalka hubinta waa in lagu rakibaa meesha laga baxo bamka iyo horteeda waalka kantaroolka laga soo baxo si loo dayactiro.Guud ahaan, meesha ugu horeysa ee bamku waa isku xidhka jilicsan ( nuugista shoogga ), oo ay ku xigto valve check , ka dibna xannibaadda valve (sida balastareedka, valve gate, valve stop, iwm.).
1. Marka hore ku rakib waalka hubinta ka dibna waalka albaabka ama waalka balanbaalista
Faa'iidooyinka: waxay ilaalin kartaa waalka hubinta, gaar ahaan matoorada barbar socda.Marka mid ka mid ah bamka uusan bilaabmin oo uu bamka kale bilaabo, xoogga saameynaya waxaa qaadaya albaabka albaabka ama valve
Khasaaraha: yaa ilaalin doona albada albaabka ama hubin doona valve?Waxaa jiray kiis ah in saxanka valve ee waalka balanbaalista uu jabay.
2. Ku rakib albaabka albaabka ama waalka balanbaalista ka hor intaadan hubin waalka
Faa'iidooyinka: waxay ilaalin kartaa waalka balanbaalista ama waalka albaabka, iyo xoogga saameynta waxaa qaadaya waalka hubinta
Khasaaro: yaa ilaalin doona waalka hubinta?Waalka hubinta waxa la furaa oo lagu xidhaa farqiga cadaadiska.Haddii cadaadiska madaxa uu sarreeyo, waa la xirayaa oo cadaadiska bamka waa la furi doonaa.Haddii socodka la isticmaalo uu yahay mid aan degganayn, valve check waa la furi doonaa oo si isdaba joog ah ayaa loo xirayaa, taas oo saameyn doonta nolosha adeegga ee waalka hubinta.
