Uma kukhulunywa ngezinhlelo zamapayipi amanzi,ivalvu yokuhlolas yizingxenye ezibalulekile. Zenzelwe ukulawula indlela yokugeleza koketshezi epayipini nokuvimbela ukugeleza emuva noma ukuphonswa emuva. Lesi sihloko sizokwethula izimiso eziyisisekelo, izinhlobo, kanye nokusetshenziswa kwama-check valve.
Isimiso esiyisisekelo se-ivalvu yokuhlolaukusebenzisa ukunyakaza kwediski yevalvu ukulawula indlela yokugeleza koketshezi. Idiski yevalvu ivame ukuklanywa ukuze ivuleke ngendlela yokugeleza koketshezi okuvamile futhi ivale ngokushesha lapho kwenzeka ukugeleza koketshezi emuva. Lo mklamo uvimbela uketshezi ukuthi lugeleze emuva futhi uvikela ubuqotho besistimu yamapayipi.
Ama-valve okuhlola eza ngezinhlobo ezahlukene, kanye nalawo avame kakhulu kufaka phakathi ibholaama-valve okuhlola, amavalvu okuhlola ukujika, kanye nama-valve okuhlola okuphakamisa. Ama-valve okuhlola ibhola asebenzisa idiski ye-valve eyindilinga evala ngokwahlukana kwengcindezi yoketshezi. Ama-valve okuhlola okujika anediski ye-valve ejikelezayo engavula noma ivale ngokuzenzakalelayo ukulawula indlela yokugeleza. Ama-valve okuhlola okuphakamisa asebenzisa idiski ye-valve ehambayo efakwe epayipini ukuze kufezwe ukulawula indlela yokugeleza.
Ama-valve okuhlola anezinhlelo eziningi emikhakheni eminingi. Ezinhlelweni zokuphakelwa kwamanzi,ama-valve okuhlolazisetshenziselwa ukuvimbela ukubuya kwamanzi nokugcina ukuqina komfutho wamanzi. Embonini yamakhemikhali, ama-check valve avimbela ukubuya kwamanzi amakhemikhali ayingozi emapayipini, ngaleyo ndlela evikela imishini nokuphepha kwabasebenzi. Embonini kawoyela negesi, ama-check valve asetshenziselwa ukuvimbela ukubuya kwamanzi kawoyela negesi nokugcina ukusebenza okuzinzile kwezinhlelo zamapayipi. Ngaphezu kwalokho, ama-check valve asetshenziswa kabanzi ekuhlanzweni kwendle, izinhlelo zokucima umlilo, izinhlelo zokupholisa umoya, kanye neminye imikhakha.
Ukuqinisekisa ukusebenza kahle kwama-check valve, ukulungiswa nokuhlolwa njalo kuyadingeka. Ama-valve disc kanye nezivalo kufanele kuhlanzwe futhi kushintshwe njalo ukuqinisekisa ukusebenza kahle. Ngaphezu kwalokho, ukukhetha kanye nendawo yokufaka ama-check valve kudingeka kucatshangelwe ngokucophelela ngokusekelwe ezidingweni ezithile zokusetshenziswa.
Ekuphetheni, ama-check valve adlala indima ebalulekile ezinhlelweni zamapayipi ngokulawula indlela yokugeleza koketshezi nokuvimbela ukubuyela emuva. Ngokukhetha uhlobo olufanele lwe-check valve, ukuqinisekisa ukufakwa okufanele, kanye nokwenza ukulungiswa njalo, ukuphepha nokusebenza okuzinzile kohlelo lwamapayipi kungaqinisekiswa.
