Emkhakheni wobunjiniyela bezimboni, ukulawula okusebenzayo nokunembayo kokugeleza koketshezi kubalulekile ekusebenzeni ngempumelelo kwezinqubo ezahlukahlukene.Ama-valve okulawula ukugeleza kwengcindezi ephezulu adlala indima ebalulekile ekuqinisekiseni ukulawulwa okubushelelezi nokuthembekile kokugeleza koketshezi ekusetshenzisweni kwezimboni okufunayo.Lawa ma-valve aklanyelwe ukumelana nezimo zengcindezi enkulu kuyilapho egcina ukulawula okunembile kokugeleza, okuwenza abe yingxenye ebalulekile yezimboni eziningi ezihlanganisa uwoyela negesi, ukucubungula amakhemikhali, ukukhiqizwa kwamandla, nokunye.
Ama-valve okulawula ukugeleza kwengcindezi ephezulu aklanyelwe ngokukhethekile ukubhekana nezinselele ezibangelwa izindawo ezinomfutho ophezulu.Ayakwazi ukumelana nokucindezela okungaphezu kwalokho kwamavalvu ajwayelekile, okuwenza alungele izinhlelo zokusebenza ezidinga ukulawulwa kokugeleza koketshezi ngomfutho ophezulu.Lawa ma-valve avame ukusetshenziswa ezinhlelweni ezibandakanya ukudluliswa koketshezi olunomfutho ophezulu, njengezinhlelo ezisebenza ngamanzi, imigqa yesitimu, namapayipi egesi anomfutho ophezulu.
Omunye wemisebenzi eyinhloko ye-valve yokulawula ukugeleza kwengcindezi ephezulu ukulawula ukugeleza koketshezi ngaphakathi kwesistimu.Ngokulungisa indawo ye-valve, ukugeleza kungalawulwa ngokunembile, kuthuthukise ukusebenza kahle kwenqubo nokugcina ukuzinza kwesistimu.Leli zinga lokulawula libalulekile ezinqubweni zezimboni, lapho ukuphathwa okunembile kokugeleza kwamanzi kubalulekile ekusebenzeni okuphelele nokuphepha kwesistimu.
Ngaphezu kokulawula ukugeleza, ama-valve okulawula ukugeleza kwengcindezi ephezulu nawo adlala indima ebalulekile ekuhlinzekeni imisebenzi yokuvala nokuhlukanisa.Ezinhlelweni zokucindezela okukhulu, ikhono lokumisa ngokushesha nangokuphumelelayo ukugeleza koketshezi libalulekile ekuvimbeleni izingozi ezingaba khona kanye nokuqinisekisa ukuphepha kwabasebenzi kanye nemishini.Lawa ma-valve aklanyelwe ukunikeza ukuvala okuthembekile ukuze ahlukanise izingxenye ezithile zesistimu lapho kudingeka.
Ngaphezu kwalokho, ama-valve okulawula ukugeleza kwengcindezi ephezulu avame ukuhlonyiswa ngezici ezithuthukisiwe ezifana nokulinganisa ingcindezi, i-anti-cavitation, namandla aphezulu okushisa.Lezi zici zenza i-valve isebenze ngokuphumelelayo ezindaweni eziyinselele lapho izici ezifana nokuhluka kwengcindezi, izici zoketshezi kanye noshintsho lokushisa kungathinta ukusebenza kwayo.Ngokuhlanganisa lezi zici eziphambili, ama-valve okulawula ukugeleza kwengcindezi ephezulu agcina ukusebenza kwawo nokuthembeka ngisho nangaphansi kwezimo zokusebenza ezinzima kakhulu.
Ukukhetha i-valve yokulawula ukugeleza kwengcindezi ephezulu efanelekile kubalulekile ukuze kuqinisekiswe ukusebenza kahle nokuphepha ezinhlelweni zokusebenza zezimboni.Lapho ukhetha i-valve yohlelo oluthile, izici ezifana nohlobo lwe-fluid, ingcindezi yokusebenza, ibanga lokushisa, kanye nezidingo zokugeleza kufanele kucatshangelwe ngokucophelela.Ukwengeza, izinto zokwakha, izindlela zokuvala, kanye nezindlela zokulawula ukusebenza kwe-actuation yizinto ezibalulekile ezithinta ukusebenza kanye nempilo yesevisi ye-valve.
Kafushane, ama-valve okulawula ukugeleza kwengcindezi ephezulu ayizici ezibalulekile ezinhlelweni zezimboni lapho ukulawulwa okunembile kokugeleza koketshezi ngaphansi kwengcindezi ephezulu kubalulekile.Lawa ma-valve ahlinzeka ngokulawula okudingekayo, ukuvala nokuvala imisebenzi edingekayo ukuze kugcinwe ukusebenza kahle nokuphepha kwezinqubo zokucindezela okukhulu.Ngokuhlanganisa izici ezithuthukisiwe nezimiso zokuklama eziqinile, ama-valve okulawula ukugeleza kwengcindezi ephezulu ahlinzeka ngokusebenza okuthembekile ezindaweni ezifunayo zezimboni.Ngokuthuthuka okuqhubekayo kobuchwepheshe, ukuthuthukiswa kwamavalvu okulawula ukugeleza kwengcindezi ephezulu kuzothuthukisa ukusebenza kahle nokuphepha kwezinqubo zezimboni, okuwenza abe yingxenye ebalulekile yobunjiniyela bezimboni zesimanje.
