Ukubonakaliswa kwevalvu yokuhlola ephukile emotweni
I-Youdaoplaceholder0 Izimpawu eziyinhloko zevalvu yokuhlola imoto enephutha zifaka phakathi ukungahlaliseki kahle, ukunyakazisa injini, ukuqala kanzima, ukukhishwa okungavamile kanye nokushiswa kukawoyela. I-Youdaoplaceholder0 Lezi zimpawu zingathinta ngqo ukusebenza kwenjini kanye nokuhlangenwe nakho kokushayela, futhi ezimweni ezimbi kakhulu zingabangela ukukhishwa kokukhishwa komoya kudlule amazinga noma kwehluleke ukuhlolwa kwaminyaka yonke.
I-Youdaoplaceholder0 Ukubonakaliswa kwamaphutha amakhulu
I-Youdaoplaceholder0 Ukungajwayelekile kokusebenza kanye nokushaqeka kwenjini.
Ijubane lokujikeleza kwenjini liyashintshashintsha kakhulu lapho ingasebenzi, futhi ingase ime ngokuzumayo.
Uma uqala, umzimba wemoto uyathuthumela kakhulu futhi isikhathi sokushisa siyandiswa.
I-Youdaoplaceholder0 Yehla ekusebenzeni okuguquguqukayo .
Ukusheshisa kubuthakathaka futhi amandla aphumayo ancishiswa kakhulu uma ukhuphuka umthambeka.
Ukusetshenziswa kahle kukaphethiloli kwehla futhi ukusetshenziswa kukaphethiloli kukhuphuka cishe ngo-10% kuya ku-15%.
Uhlelo lokukhipha olungavamile lwe-Youdaoplaceholder0.
Ukukhishwa okukhulu komoya ophumayo kungaholela kalula entuthwini emnyama (nge-valve yokuhlola evulekile njalo) noma entuthwini eluhlaza okwesibhakabhaka (ukushisa uwoyela wenjini).
Ukwanda kokukhishwa kwe-nitrogen oxide kuphakamise ingozi yokwehluleka ukuhlolwa kwaminyaka yonke.
I-Youdaoplaceholder0 Uhlelo lwesixwayiso luqala .
I-valve yokuhlola izimoto iyithuluzi lokulawula uketshezi. Umgomo wayo oyinhloko ukuvumela uketshezi (njengomoya noma uwoyela) ukuthi lugeleze ngokukhululeka ohlangothini olulodwa kuphela ngenkathi kuvimbela ukugeleza okuphambene. Lokhu kufezwa kakhulu ngokusebenzisana kwe-valve core yangaphakathi, ispring kanye nesihlalo se-valve: lapho ingcindezi yangaphambili idlula ukumelana nokungqubuzana kwespring, i-valve core iyacindezelwa ivuleke, ivule isiteshi. Uma ingaphansi kwengcindezi ephindaphindayo, i-valve core icindezelwa esihlalweni se-valve, ivale isiteshi futhi iqinisekise ukugeleza okuqondile.
Ezinhlelweni zezimoto, ama-check valve asetshenziswa kabanzi, futhi izimiso zawo zokusebenza kanye nemisebenzi ziyahlukahluka kuye ngokuthi indawo yokufaka ifakiwe:
I-Youdaoplaceholder0 I-valve yokuhlola ibhalansi yomnyango : Uma ifakiwe ebhuthini noma emnyango, ivumela umoya ocindezelwe kakhulu ngaphakathi emotweni ukuthi ukhishwe ohlangothini olulodwa (isibonelo, lapho uvula noma uvala umnyango noma uqala ukujikeleza kwegazi kwangaphandle), ivimbela umnyango ukuthi ungabi nzima ukuwuvala ngenxa yokungalingani kwengcindezi; Ngakolunye uhlangothi, uzovalwa ukuze kuvinjelwe ukungcola kwangaphandle ukuthi kungangeni.
I-Youdaoplaceholder0 I-valve yokuhlola isivalo sethangi likaphethiloli : Yakhelwe ukufana ne-valve yokuhlola, ivumela umoya wangaphandle ukuthi ungene ethangini ohlangothini olulodwa ukuze ugcwalise umoya-mpilo futhi ulondoloze ibhalansi yomfutho womoya (njengokusetshenziswa kukaphethiloli ngesikhathi sokushayela); Kodwa vimbela uphethiloli noma umusi ekuphumeni ukuqinisekisa ukuphepha nokuvikelwa kwemvelo.
I-Youdaoplaceholder0 I-Crankcase ventilation check valve : Itholakala ohlelweni lokungenisa umoya lwe-crankcase yenjini, ilawula ivolumu yokugeleza kwegesi yokukhipha (njengokunciphisa isiteshi lapho singasebenzi futhi sande lapho sithwele umthwalo omkhulu); Ngesikhathi esifanayo, ivimbela umlilo ukuthi ungavuthisi igesi yokukhipha. Uma yonakele, izoholela ekusetshenzisweni okungajwayelekile kukawoyela wenjini (njengoba yehluleka ukuvimbela ngempumelelo amaconsi kawoyela ukuthi angangeni esilinda kanye negesi yokukhipha).
Zonke lezi zinhlelo zokusebenza zincike esakhiweni esilula sevalvu yokuhlola (umzimba wevalvu, umongo wevalvu, isipilingi) ukuqinisekisa ukusebenza okuzinzile kwezinhlelo ezibalulekile zemoto.
Umsebenzi oyinhloko we-valve yokuhlola imoto ukulawula ukugeleza koketshezi oluqondile (njengowoyela wenjini, igesi yokukhipha uphethiloli, uphethiloli, njll.) ohlelweni, ukuvimbela ukugeleza emuva, ngaleyo ndlela kuqinisekiswe ukusebenza kwenjini, kuncishiswe ukukhishwa komoya futhi kuthuthukiswe ukuzinza kohlelo.
Imisebenzi eyinhloko ye-Youdaoplaceholder0 kanye nezimo zohlelo lokusebenza
I-Youdaoplaceholder0 Vimbela ukugeleza koketshezi emuva.
I-valve yokuhlola iqinisekisa ukuthi uketshezi olubalulekile lwemoto olufana namafutha enjini, uketshezi lwamabhuleki kanye nophethiloli kungageleza kuphela ngendlela eklanywe ngayo, kugwenywe ukulimala kwephampu kaphethiloli noma ukucindezeleka okunganele kukaphethiloli okubangelwa ukugeleza okuphambene. Isibonelo, uma ifakwa endaweni yokukhipha iphampu kaphethiloli, ingavimbela uphethiloli ukuthi ubuyele ethangini likaphethiloli ngemva kokuba injini icishiwe, okuqinisekisa ukuthi ukucindezeleka kukaphethiloli kuqiniswa ngokushesha ngesikhathi sokuqalisa.
I-Youdaoplaceholder0 Lawula ukugeleza kwegesi yokukhipha umoya .
Kuhlelo lokujikeleza kabusha kwegesi yokukhipha injini (i-EGR), i-valve yokuhlola iqondisa igesi yokukhipha ukuthi ingene ekamelweni lokushisa iye ohlangothini olulodwa kuphela, okungagcini nje ngokunciphisa ukukhishwa kwama-nitrogen oxide kodwa futhi kugcina amandla enjini ephumayo.
I-Youdaoplaceholder0 Vikela ukuqiniswa kwengcindezi yesistimu .
Uma kuhlanganiswa nezinhlelo ze-hydraulic noma ze-pneumatic, ama-check valve angavimbela izinguquko zengcindezi ezisheshayo ezonakalisa izingxenye (njengezimpompi zikawoyela), noma alungise kancane kancane ingcindezi ngama-pressure valve alandelanayo ukuze agweme umthelela wamandla okusabela ohlelweni.
I-Youdaoplaceholder0 Imisebenzi ekhethekile yokuklama nokuhlanganisa
Ukusetshenziswa kwe-valve ehlanganisiwe ye-Youdaoplaceholder0 : Uma ixhunywe ngokuhambisana ne-valve ye-throttle, ivumela ukugeleza okuhamba kancane phambili kanye nokugeleza okusheshayo kokubuyela emuva; Uma ihlanganiswe ne-valve yokunciphisa ingcindezi, ingenza ngcono ukusebenza kahle kokulawula uketshezi.
Ukufakwa kwesistimu yokupholisa umoya i-Youdaoplaceholder0: Emjikelezweni wokuqandisa, i-valve yokuhlola isebenza ngokubambisana ne-capillary tube ukulungisa ukuhamba kwe-refrigerant ukuze kwandiswe umphumela wokushisa.
Ukwehluleka kwe-Youdaoplaceholder0 kuthinta
Uma i-check valve yonakele, kungaholela ebunzimeni ekuqaliseni ukugeleza kukaphethiloli emuva, uwoyela wenjini udonswe epayipini lokungenisa (i-vacuum eningi ngesivinini esiphansi), noma ukungalingani kwengcindezi yesistimu okubangela umonakalo wezingxenye.
