I-Liwei Injector Nozzle entsha Dlla143p2155 0433172155 OE 4988835 Bh1X9K526ca 570107999909 for Fuel Injector 0445120161 0445120204 for 245 Diesel.

Indawo yekhoni yokuvala yokuhlangana kwevalvu yenaliti itholakala ekugcineni okuphansi kakhulu kokuhlangana, futhi inezingxenye ezimbili: i-valve yenaliti yokuvala i-cone surface kanye ne-valve yenaliti yomzimba yokuvala indawo yekhoni.Iziphetho ezimbili zekhoni yokuvala ngokulandelana ziwuphethiloli wengcindezi ephezulu evela ethangini likawoyela kanye nengcindezi yesilinda exhunywe embotsheni yomjovo, okuyizindawo zokuvala ezilawula ngqo umjovo kaphethiloli.Ngenxa yomphumela we-extrusion we-valve yenaliti endaweni yesihlalo somzimba we-valve, kwakheka indawo encane yokuxhumana phakathi kwekhoni yokuvala ye-valve yenaliti kanye ne-cone yokuvala yomzimba we-valve yenaliti.Impahla ye-valve yenaliti kanye nomzimba we-valve yenaliti iyadingeka ukuze ibe nokuqina okuphezulu nokumelana nokugqoka, futhi insimbi ethwalayo noma insimbi enesivinini esikhulu enempatho ekhethekile isetshenziswa ngokujwayelekile.Ngenxa yomthelela oqhubekayo phakathi kwe-valve yenaliti kanye nesihlalo somzimba we-valve kanye nomthelela wokushisa okuphezulu nokucindezela okuphezulu okukhiqizwa ukushiswa kwesilinda sangaphandle, indawo yekhoni evala uphawu ijwayele ukuguga futhi idabuke, okuholela ekuvaleni kahle nokudonsa kukaphethiloli. .Ukucindezeleka kokuxhumana kwekhoni yokuvala kukhulu kakhulu, futhi imikhiqizo eminingi izokwenziwa i-carburized noma ifuthwe ukuze kuqinisekiswe ukuthi i-cone yokuvala ingagcina izici ezinhle zokuvala isikhathi eside ezindaweni ezinzima.Ngakho-ke, ukubekwa uphawu kombhangqwana we-valve yenaliti kusebenzisa kokubili uphawu lwefilimu yamafutha ehambayo kanye ne-static contact seal.

Ukuhlangana kwevalvu yenaliti kungenye yezinto ezintathu ezinembayo zokuhlanganisa uhlelo lomjovo lukadizili.Ivame ukugqokwa ngesivinini esikhulu, ukucindezela okuphezulu kanye nezinhlayiya zokungcola kuphethiloli ngesikhathi somsebenzi, okuholela ekunciphiseni kokusebenza kokuvala.
