1. Izinga lokushisa likaphethiloli esikhaleni esiphakathi kwezingxenye zokuhlanganisa ivalvu yenaliti:

Lapho i-valve yenaliti iphindaphinda, amandla e-kinetic alahleka ukungqubuzana kokugeleza kwe-shear phakathi kombhangqwana we-valve yenaliti kanye nophethiloli wegebe aguqulwa abe amandla okushisa, kanye negebe.

Ukushisa kwefilimu kawoyela kuphakama kancane kancane, futhi uphethiloli uzokhula lapho izinga lokushisa likhuphuka, ukuze kube nokucindezela okwengeziwe kwefilimu yamafutha kugebe.

insimu, umthamo womthwalo wefilimu kawoyela uyakhula, lesi simo siwumphumela wokushisa oshisayo.Uma ukugeleza kwe-shear kungacatshangwa, izinga lokugeleza kwamafutha liyancishiswa ngenxa yokumelana ne-viscous odongeni.Uma i-valve yenaliti imile noma ihamba ngesivinini esiphansi, ukulahlekelwa kwengcindezi kaphethiloli konke kuguqulwa kube amandla okushisa.Ngesikhathi esifushane, ukushisa kunzima ukudlulisela odongeni oluqinile, ngakho-ke kwenziwa lula njengenqubo ye-adiabatic.

2. Ukuvuza esikhaleni sendandatho yesixhumi senaliti se-valve:

I-valve yenaliti yokuhlanganisa ivalwe ngefilimu kawoyela esikhaleni, futhi ubukhulu befilimu kawoyela bungaba ngu-2.μm.Lolu hlobo lwegebe lendandatho ye-micron lusetshenziswa kakhulu ekucindezelweni okuphezulu nokuvala uphawu ngesivinini esikhulu.Ukugeleza kwenhlanganisela ye-shear enamandla.Usayizi wegebe lombhangqwana wevalvu yenaliti mncane kakhulu.Ithembele kudizili ukuze ikwazi ukuzithambisa.Uma igeleza esikhaleni sezinga le-micron, i-viscosity yamafutha edizili inkulu, futhi inombolo ye-Reynolds incane.kungabonakala njengezendlalelo.

3. Ukuguqulwa kwe-radial kokuhlangana kwevalvu yenaliti:

Njengoba ingcindezi yesistimu yokuhlinzeka uphethiloli ikhula, i-groove yokugcina uwoyela kanye ne-sliding surface clearance yomhlangano we-valve yenaliti kungaphansi komthwalo omkhulu.Ibangela ukubola okunwebekayo kokuhlangana kwevalvu yenaliti, iguqule ukushuba kwefilimu ye-radial yefilimu kawoyela esikhaleni esiphakathi kokuhlangana kwevalvu yenaliti, futhi ngaleyo ndlela ithinte izici zokuvala zokuhlangana kwevalvu yenaliti.
