Iyini intwasahlobo yevalvu yemoto
Intwasahlobo yevalvu yemoto iyisici esibalulekile senjini, esitholakala phakathi kwekhanda lesilinda kanye nesihlalo sentwasahlobo ekugcineni kwesiqu sevalvu. Umsebenzi wayo oyinhloko ukuqinisekisa ukuthi ivalvu ilingana kahle nesihlalo sevalvu uma ivaliwe, ukuvimbela ukudlidliza ekubangeni ukugxuma nokulimaza ukusebenza kokuvala.
Isakhiwo Nezinto Ezisetshenziswayo
Ngokuvamile yenziwe ngocingo lwensimbi oluxubile olusezingeni eliphezulu (njengentambo yensimbi ye-chromium-vanadium noma ucingo lwensimbi ye-silicon-chromium), futhi iphathwa ngokushisa ukuze kuthuthukiswe amandla okukhathala. Ubuso buqiniswe nge-galvanized noma nge-phosphate ukuze kuvinjelwe ukugqwala. Iziphetho ezimbili zesiphethu kudingeka zibe phansi futhi ziqonde ngqo ku-axis ukuze kugwenywe ukugoba ngesikhathi sokusebenza.
Umsebenzi kanye nokubaluleka
I-Youdaoplaceholder0 Nqoba amandla angasebenzi: Nqoba amandla angasebenzi ezingxenyeni zokudlulisa ngesikhathi senqubo yokuvala ivalvu ukuze uvimbele ukwakheka kwezikhala phakathi kwezingxenye ngenxa ye-inertia.
I-Youdaoplaceholder0 I-Anti-vibration kanye ne-runout : Vimbela ama-valve ukuthi angagxumi lapho injini idlidliza ukuqinisekisa ukuvala futhi ugweme ukuvuza komoya noma ama-valve awele esilinda bese ebangela umonakalo.
Ukulungiswa komklamo we-Youdaoplaceholder0 : Isebenzisa kakhulu isakhiwo se-double-spring (esineziqondiso zokujikeleza zangaphakathi nezangaphandle eziphambene), okuthuthukisa ikhono lokulwa nokuzwakala futhi kufinyeze ubude. Ngisho noma i-spring eyodwa iphuka, isengagcina eminye imisebenzi.
Imisebenzi yeziphethu ze-valve zezimoto ifaka phakathi izici ezintathu ezilandelayo:
Qiniseka ukuthi amavalvu ayavalwa ngesikhathi futhi angena kahle
Isiphethu sevalvu siqinisekisa ukuthi ivalvu inamathela eduze esihlalweni sevalvu noma indandatho yesihlalo sevalvu uma ivaliwe ngenxa yokucindezeleka kwayo, okuvimbela ivalvu ukuthi ingagxumi futhi yonakalise ukusebenza kokuvala ngenxa yokudlidliza kwenjini.
Nqoba amandla angasebenzi
Uma ivalvu ivuliwe, isiphethu sidinga ukunqoba amandla angenantambo esitimela sevalvu ukuqinisekisa ukuthi izingxenye zokudlulisa zihlala zilawulwa yi-CAM. Uma amavalvu evaliwe, kuyadingeka ukunqoba amandla angenantambo amavalvu nezingxenye zokudlulisa ukuze kugwenywe ukwakheka kokuphuma ngenxa ye-inertia.
Vimbela ukuzwakala komsindo
Yamukela ukwakheka kwe-pitch eguquguqukayo noma i-double spring (njenge-double spring phakathi nendawo) ukunciphisa ingozi yokuhlangana phakathi kwemvamisa yokusebenza kanye nemvamisa yemvelo, futhi ivimbele ukuphuka kwentwasahlobo. Isakhiwo se-double spring singagcina neminye imisebenzi lapho eyodwa iphuka, okuthuthukisa ukuthembeka.
Ukuphuka kwentwasahlobo ye-valve kungabangela ukusebenza okungajwayelekile kwenjini, okubonakala ngqo kanje:
Ubunzima ekuqaleni
Isiphethu sevalvu esiphukile singabangela ukuthi amavalvu ahluleke ukuvula noma ukuvala ngendlela evamile, okuthinta ngqo ukuqalisa kwenjini.
Amandla angazinzile
Ukusebenza okungajwayelekile kwama-valve kungaholela ekunciphiseni ukusebenza kahle kokungenisa kanye nokukhipha ugesi, okubangela izinkinga ezifana nokukhishwa kwamandla okungazinzile kanye nokusetshenziswa kukaphethiloli okwandisiwe.
Umsindo uyanda
Ukungqongqoza kwe-valve okungavamile kungadala umsindo owengeziwe, futhi ezimweni ezimbi kakhulu, kungase kuhambisane nomsindo wokungqubuzana kwensimbi.
Ukuthuthumela nomsindo ongajwayelekile
Ukuzamazama ngezikhathi ezithile kungenzeka ngesikhathi sokusebenza kwenjini, futhi imisindo engavamile ingahambisana nokuphenduka kwesiteringi kwamanye amamodeli.
Iziphakamiso zokulungisa
Kunconywa ukuthi kwenziwe ukulungiswa okusheshayo, kushintshwe isiphethu esonakele bese kuhlolwa izingxenye ezifanele (njengeziqondiso zama-valve, ama-camshaft bearings, njll.). Uma kungalungiswanga ngesikhathi, kungabangela ukuthi injini ishise ngokweqile noma yonakale kakhulu.
Intwasahlobo yevalvu itholakala phakathi kwekhanda lesilinda kanye nesihlalo sentwasahlobo ekugcineni kwesiqu sevalvu. Umsebenzi wentwasahlobo yevalvu ukuqinisekisa ukuthi ivalvu ingaxhunywa eduze nesihlalo sevalvu noma indandatho yesihlalo sevalvu lapho ivalvu ivaliwe, kanye nokunqoba amandla angenawo amandla akhiqizwa yisitimela sevalvu lapho ivalvu ivuliwe, ukuze izingxenye zokudlulisela zihlale zilawulwa yi-CAM futhi zingahlukani.
Iziphethu zamavalvu ngokuvamile zenziwe ngocingo lwensimbi oluyi-alloy olusezingeni eliphezulu futhi ziyashiswa ukuze kuthuthukiswe amandla azo okukhathala. Ukuze kuvinjelwe ukuthi isiphethu singagqwali, ubuso besiphethu kufanele buqiniswe nge-galvanized futhi bufakwe i-phosphate. Iziphetho ezimbili zesiphethu kumele zibe yisicaba futhi ziqonde ngqo ku-axis yesiphethu ukuze kuvinjelwe ukuthi isiphethu singathambeki ngesikhathi sokusebenza.
Iziphethu zamavalvu ikakhulukazi ziyiziphethu ezilengayo eziyisilinda, njengoba kuboniswe kuMfanekiso 1. Uma imvamisa yokusebenza yesiphethu samavalvu ilingana noma i-integer multiple yemvamisa yayo yemvelo, isiphethu samavalvu sizozwakala, okwandisa amathuba okuphuka. Ukuze kuvinjelwe ukugqama komsindo, iziphethu ezinama-variable pitch zingasetshenziswa. Njengamanje, izinjini eziningi zisebenzisa iziphethu ezimbili ezifakwe ngokugxilile. Iziqondiso zokujikeleza kweziphethu zangaphakathi nezangaphandle ziphambene, futhi ukuqina kwesiphethu sangaphandle kukhulu kunokwesiphethu sangaphakathi. Iziphethu ezimbili azigcini nje ngokuvimbela ukugqama komsindo kodwa futhi zifinyeza ubude beziphethu. Futhi lapho esinye seziphethu sigqamuka, esinye isiphethu sisaqhubeka nokusebenza, sivimbela ivalvu ukuthi iwele kusilinda.
