Uma kukhulunywa ngezinhlelo zepayipisi,Bheka i-valveizingxenye ezibalulekile. Zenzelwe ukulawula ukuqondiswa kokugeleza koketshezi epayipini futhi kuvikele ukubuyela emuva noma ukubuyela emuva kwe-siphonage. Le ndatshana izokwethula izimiso eziyisisekelo, izinhlobo, kanye nokusetshenziswa kwama-valve ama-Check.
Isimiso esiyisisekelo seBheka i-valveukusebenzisa ukunyakaza kwe-valve disc ukulawula ukuqondiswa kokugeleza koketshezi. I-Valve disc ijwayele ukuklanywa ukuvula ekuqondisweni kokugeleza kwamanzi okujwayelekile bese uvala ngokushesha lapho kubuyela emuva emuva. Lo mklamo uvimbela uketshezi ukuthi lugeleze emuva futhi luvikele ubuqotho bohlelo lwepayipi.
Bheka ama-valves eza ngezinhlobo ezahlukahlukene, ezivame kakhulu kufaka phakathi ibholaBheka ama-valves, Swing hlola ama-valves, kanye nokuphakamisa ama-valves okuhlola. Ama-valves wokuhlola ibhola asebenzisa i-spherical valve disc evala ngokuhlukile kwengcindezelo yoketshezi. Ama-Swing Check Valves anokujikeleza i-valve ejikelezayo engavula ngokuzenzakalela noma eduze nokulawula indlela yokugeleza. Ama-valves wokuhlola ama-lift asebenzisa i-valve valve eshukumisayo efakwe epayipini ukuze afinyelele kulawulo lokuqondisa ukugeleza.
Bheka ama-valves anezicelo ezibanzi emikhakheni eminingi. Ezinhlelweni zokuhlinzekwa kwamanzi,Bheka ama-valveszisetshenziselwa ukuvikela ukubuyela emuva kwamanzi futhi zilondoloze ukuqina kwengcindezi yamanzi. Embonini yamakhemikhali, ama-valves ahlola avimbela ukubuyela emuva kwamakhemikhali ayingozi kumapayipi, ngaleyo ndlela ukuvikela imishini nokuphepha kwabasebenzi. Embonini kawoyela negesi, kusetshenziselwa ama-valves okuhlola ukuvimbela ukubuyela emuva kwamafutha negesi futhi kugcinwe ukusebenza kwezinzisi zamapayipi. Ngokwengeziwe, ama-valves okuhlola asetshenziswa kabanzi ekuphathweni kwendle, amasistimu wokucindezela umlilo, amasistimu wokufaka umoya, nezinye izinkambu.
Ukuqinisekisa ukusebenza okusebenzayo kwama-valves okuhlola, ukulungiswa okujwayelekile kanye nokuhlolwa kuyadingeka. Ama-Dalve Disc kanye nezimpawu kufanele zihlanzwe futhi zishintshwe ngezikhathi ezithile ukuze ziqinisekise ukusebenza kahle. Ngaphezu kwalokho, isikhundla sokukhethwa kanye nokufakwa kwama-valves okuhlola kudingeka kubhekwe ngokucophelela ngokusekelwe kwizidingo ezithile zohlelo lokusebenza.
Ekuphetheni, bheka ama-valves adlala indima ebalulekile ezinhlelweni zamapayipi ngokulawula ukugeleza koketshezi kanye nokuvimbela emuva. Ngokukhetha uhlobo olufanele lokuhlola i-valve, ukuqinisekisa ukufakwa okufanele, nokwenza ukulungiswa okujwayelekile, ukuphepha nokuzinza kohlelo lwepayipi kungaqinisekiswa.
