Xa kuziwa kwiinkqubo zemibhobho yamanzi,khangela ivalves ngamacandelo abalulekileyo. Zenzelwe ukulawula ulwalathiso lokuhamba kwamanzi kumbhobho kunye nokukhusela umva okanye ukubuyisela umva. Eli nqaku liza kwazisa imigaqo esisiseko, iintlobo, kunye nokusetyenziswa kweevalvu zetshekhi.
Umgaqo osisiseko akhangela ivalvekukusebenzisa intshukumo yediskhi yevalvu ukulawula icala lokuhamba kolwelo. I-valve disc idla ngokuyilwa ukuba ivuleke kwicala lokuhamba kolwelo oluqhelekileyo kwaye ivale ngokukhawuleza xa kuphuma umva. Olu yilo luthintela ulwelo ukuba lungabuyeli ngasemva kwaye lukhusela ingqibelelo yenkqubo yemibhobho.
Iivalvu zokujonga ziza kwiindidi ezahlukeneyo, kunye nezona ziqhelekileyo eziquka ibholakhangela iivalve, swing check valves, kwaye uphakamise iivalve zokujonga. Iivalvu zokujonga ibhola zisebenzisa idiskhi yevalve engqukuva evala ngokwahlukana koxinzelelo lolwelo. Iivalvu zokukhangela i-Swing zine-disc yevalve ejikelezayo enokuthi ivule okanye ivale ngokuzenzekelayo ukulawula indlela yokuhamba. Iivalvu zokujonga ukuphakamisa zisebenzisa idiski yevalve eshukumayo efakwe kumbhobho ukufikelela kulawulo lwendlela yokuhamba.
Iivalvu zokujonga zinosetyenziso olubanzi kwiindawo ezininzi. Kwiinkqubo zokubonelela ngamanzi,khangela iivalvezisetyenziselwa ukuthintela ukubuya kwamanzi kunye nokugcina ukuzinza koxinzelelo lwamanzi. Kwishishini lemichiza, ii-valve zokutshekisha zithintela umva kweekhemikhali ezinobungozi kwimibhobho, ngaloo ndlela zikhusela izixhobo kunye nokhuseleko lwabasebenzi. Kwishishini leoli kunye negesi, i-valve yokutshekisha isetyenziselwa ukuthintela ukubuyela ngasemva kweoli kunye negesi kunye nokugcina ukusebenza okuzinzileyo kweenkqubo zemibhobho. Ukongeza, iivalve zokukhangela zisetyenziswa ngokubanzi kunyango lwelindle, iinkqubo zokucima umlilo, iinkqubo zomoya, kunye nezinye iindawo.
Ukuqinisekisa ukusebenza kakuhle kwee-valve zokutshekisha, ukugcinwa rhoqo kunye nokuhlolwa kuyimfuneko. Iidiski zevalve kunye nezitywina kufuneka zicocwe kwaye zitshintshwe ngamaxesha athile ukuqinisekisa ukusebenza kakuhle. Ngaphezu koko, ukhetho kunye nokufakela indawo yee-valve zokutshekisha kufuneka ziqwalaselwe ngononophelo ngokusekelwe kwiimfuno ezithile zesicelo.
Ukuqukumbela, iivalvu zokutshekisha zidlala indima ebalulekileyo kwiinkqubo zemibhobho ngokulawula indlela yokuhamba kwamanzi kunye nokuthintela ukubuya umva. Ngokukhetha uhlobo olufanelekileyo lwe-valve yokukhangela, ukuqinisekisa ukufakwa ngokufanelekileyo, kunye nokwenza ukugcinwa rhoqo, ukhuseleko kunye nokusebenza okuzinzile kwenkqubo yombhobho kunokuqinisekiswa.
