Isimiso sokusebenza se-valve yokuhlola.

Ama-valve okuhlola angasetshenziswa futhi kumapayipi lapho ingcindezi ohlelweni olusizayo ingase ikhuphuke ngaphezu kwengcindezi yesistimu.Hlola ama-valvezingahlukaniswa ngokuyinhloko zibe amavalvu okuhlola ukujika (azungeza phakathi nendawo amandla adonsela phansi) futhi aphakamise amavalvu okuhlola (anyakaza eduze kwe-eksisi).

Umsebenzi walolu hlobo lwe-valve yokuhlola ukuvumela okuphakathi ukuthi kugeleze endaweni eyodwa kuphela futhi kuvimbele ukugeleza okubuyela emuva. Ngokuvamile, le valve isebenza ngokuzenzakalelayo. Ngaphansi kwengcindezi yoketshezi olugeleza ohlangothini olulodwa, i-valve disc ivula; lapho uketshezi lugeleza ngakolunye uhlangothi, ukucindezela kwamanzi kanye nesisindo somuntu we-valve disc sisebenza esihlalweni se-valve, ngaleyo ndlela sinqamule ukugeleza.

I-valve yokuhlola ingenye yezinhlobo ezinjalo ze-valve. Kuhlanganisa ama-valve okuhlola ama-swing nama-valve okuhlola okuphakamisa. I-valve yokuhlola i-swing ine-hinge mechanism kanye nediski ye-valve ephumula ngokukhululekile endaweni yesihlalo se-valve ethambekele njengomnyango. Ukuqinisekisa ukuthi i-disc ye-valve ingahlala ifinyelela endaweni efanele esihlalweni se-valve isikhathi ngasinye, i-disc ye-valve iklanywe ngendlela ye-hinge ukuze i-disc ye-valve ibe nesikhala esanele sokushwibeka futhi ingathinta ngempela futhi ngokuphelele isihlalo se-valve. I-valve disc ingenziwa ngokuphelele ngensimbi noma ingaba nesikhumba, irabha, noma isembozo sokwenziwa esifakwe kuyo, kuye ngezidingo zokusebenza.

Lapho i-valve yokuhlola i-swing ivuleke ngokugcwele, umfutho we-fluid cishe awuvimbeli, ngakho ukwehla kwengcindezi ku-valve kuncane kakhulu. I-disc ye-valve yokuhlola i-lift itholakala endaweni yokuvala yesihlalo esiphezulu se-valve yomzimba. Le valve, ngaphandle kokuvumela i-disc ukuthi ikhuphuke futhi iwe ngokukhululekile, inesakhiwo esifanayo ne-valve yokumisa. Ukucindezela kwamanzi kubangela ukuthi i-disc iphakamise indawo yokuvala yesihlalo se-valve, futhi ukubuya kwe-medium kubangela ukuthi i-disc ibuyele esihlalweni se-valve futhi inqamule ukugeleza.

Ngokuya ngezimo zokusebenza, i-valve disc ingaba yesakhiwo sensimbi ngokugcwele noma ngesimo sephedi yerabha noma indandatho yerabha eshumekwe kuhlaka lwediski ye-valve. Njenge-valve yokumisa, ukugeleza kwevalve yokuhlola i-lift nakho kuncane, ngakho-ke ukwehla kokucindezela nge-valve yokuhlola i-lift kukhulu kunaleyo ye-valve yokuhlola i-swing, futhi umkhawulo wokugeleza we-valve yokuhlola i-swing mncane kakhulu.
