Isebenza kanjani i-valve yokuhlola?

Hlola ama-valveingasetshenziswa futhi emigqeni ehlinzeka ngezinhlelo ezisizayo lapho ukucindezela kungase kukhuphuke ngaphezu kokucindezela kwesistimu. Ama-valve okuhlola angahlukaniswa ikakhulukazi ama-valve okuhlola ama-swing (azungezayo ngokuya phakathi nendawo ye-gravity) kanye nama-valve okuhlola okuphakamisa (ahamba eduze kwe-eksisi).
Inhloso yalolu hlobo lwe-valve ukuvumela i-medium ukuthi igeleze ohlangothini olulodwa kuphela futhi ivimbele ukugeleza kolunye uhlangothi. Ngokuvamile lolu hlobo lwe-valve lusebenza ngokuzenzakalelayo. Ngaphansi kwesenzo sokucindezela kwamanzi okugeleza ohlangothini olulodwa, i-valve flap iyavuleka; lapho uketshezi lugeleza ngakolunye uhlangothi, umfutho we-fluid kanye ne-self-coincident valve flap ye-valve flap isebenza esihlalweni se-valve, ngaleyo ndlela inqamule ukugeleza.
Phakathi kwabo, i-valve yokuhlola ingeyalolu hlobo lwe-valve, oluhlanganisajika i-valve yokuhlolabese uphakamisa i-valve yokuhlola. Amavalvu okuhlola ama-Swing ane-hinge mechanism kanye nediski elifana nomnyango elihlala ngokukhululeka endaweni yesihlalo esitshekile. Ukuze kuqinisekiswe ukuthi i-disc ye-valve ingafinyelela indawo efanele yesihlalo se-valve ngaso sonke isikhathi, i-disc ye-valve iklanywe ku-hinge mechanism, ukuze i-disc ye-valve ibe nesikhala esanele sokushwibeka futhi yenza i-disc ye-valve ithinte ngempela futhi ngokugcwele isihlalo se-valve. I-disc ingenziwa ngokuphelele ngensimbi, noma ihlanganiswe ngesikhumba, irabha, noma izembozo zokwenziwa, kuye ngezidingo zokusebenza. Esimeni esivuleke ngokuphelele se-valve yokuhlola i-swing, umfutho we-fluid cishe awuphazamiseki, ngakho-ke ukwehla kwengcindezi ku-valve kuncane kakhulu. I-disc ye-valve yokuhlola i-lift itholakala endaweni yokuvala yesihlalo se-valve emzimbeni we-valve. Ngaphandle kokuthi i-disc ye-valve ingakhuphuka futhi iwe ngokukhululeka, yonke i-valve ifana ne-globe valve. Umfutho we-fluid uphakamisa i-disc ye-valve endaweni yokuvala yesihlalo se-valve, futhi ukubuyela emuva kwe-medium kubangela i-disc ye-valve ukuthi ibuyele esihlalweni se-valve futhi inqamule ukugeleza. Ngokwemibandela yokusetshenziswa, i-disc ingaba yesakhiwo sensimbi yonke, noma ingaba ngesimo se-rubber pad noma indandatho yerabha efakwe kumnikazi wediski. Njenge-valve yembulunga, ukudlula koketshezi ngevalvu yokuhlola i-lift nakho kuncane, ngakho ukwehla kwengcindezi ngevalvu yokuhlola i-lift kukhulu kunaleyo yevalve yokuhlola i-swing, futhi ukugeleza kwe-valve yokuhlola i-swing kulinganiselwe.
