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 e-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-valve disc ingafinyelela endaweni efanele yesihlalo se-valve ngaso sonke isikhathi, i-disc ye-valve yakhelwe kumshini we-hinge, ukuze i-disc ye-valve ibe nesikhala esanele sokushwibeka futhi yenze i-disc ye-valve ixhumane ngempela futhi ngokuphelele. isihlalo se-valve.I-disc ingenziwa ngokuphelele ngensimbi, noma ihlanganiswe ngesikhumba, irabha, noma izembozo zokwenziwa, kuye ngezidingo zokusebenza.Esimeni esivuleke ngokugcwele 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 ukugeleza kwe-backflow ye-medium kubangela ukuthi i-disc ye-valve 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 ngevalve yokuhlola i-lift nakho kuncane, ngakho ukwehla kwengcindezi ngevalvu yokuhlola i-lift kukhulu kunaleyo ye-valve yokuhlola i-swing, futhi ukugeleza kwe-valve yokuhlola i-swing kulinganiselwe.
