Imithombo yeValve zizinto eziphambili ezichaphazela ukusebenza kwe-injini.Basebenza njengebhuloho phakathi kwecamshaft kunye neevalve, ukuqinisekisa ukuba iivalve zivale ngexesha elifanelekileyo kwaye zivule ngexesha elifanelekileyo.Ngemithombo yevalvu edlala indima ebaluleke kangaka ekusebenzeni kwenjini, ayimangalisi into yokuba uninzi lwabathandi bemoto bafuna ukufumana okuninzi kubo.Kule bhlog, sixoxa ngobuchule bobuchule bokwandisa imveliso yenjini ngokusebenzisa imithombo yevalvu.
Ukuqonda iValve Springs
Ngaphambi kokuba singene kwiinkcukacha zokwandisa ukusebenza kwe-valve spring spring, kubalulekile ukuqonda ukuba zisebenza njani.Imithombo ikwiingalo ze-rocker kwaye idibanisa kwiziqu zevalve.Xa i-valve ivuliwe, intwasahlobo ithatha amandla, inceda i-valve ibuyele kwindawo evaliweyo.Imithombo yeValve iza ngobukhulu obahlukeneyo kunye namandla ngokuxhomekeke kwimveliso yamandla enjini kunye neprofayile yecamshaft.
Kwi-injini yokusebenza okuphezulu, iivalvu kufuneka zivule kwaye zivale ngokukhawuleza kune-injini eqhelekileyo.Ngenxa yoko, ii-injini ezisebenza ngokuphezulu zifuna imithombo yevalvu eqinile ukuze ilawule amandla awongezelelekileyo adalwe ziilobe ezindlongondlongo zecamshaft.Imithombo yevalve eqinile ikhusela iivalve ekuxhumeni nasekungazinzini, nto leyo enokubangela umonakalo omkhulu we-injini.
Imithombo yeValve kunye nePhulo leNjini
Ngoku, makhe singene kwiinkcukacha zendlela imithombo yevalvu ephucula ngayo imveliso yenjini.Imithombo yeValve inokuchaphazela ukusebenza kwe-injini ngeendlela ezininzi, kubandakanya:
1. Amandla: Imithombo yeValve inempembelelo enkulu kwi-RPM ephezulu ye-injini.Xa i-injini isebenza kwi-rpm ephezulu, iivalvu ziyavala kwaye zivuleke ngesantya esimangalisayo.Imithombo yevalve ebuthathaka ayizivali iivalvu ngokukhawuleza ngokwaneleyo, nto leyo ebangela ukuba injini isebenze ngokungalunganga.
2. Ukuqina: Ubomi bentlakohlaza yevalvu bubalulekile kubomi benjini.Ivalve engavaleki ngokupheleleyo inokubangela umonakalo kwisitulo sevalve okanye kwintloko yesilinda, nto leyo enokukhokelela ekugqibeleni kwintlekele ye-injini.
3. Ukunyuswa kweValve: Ukunyuswa kweValve yenye into ebalulekileyo ekusebenzeni kwenjini.Xa ukuphakama kunyuswa, kubangela ukunyuka komoya, okukhokelela ekuphumeni kwamandla aphezulu.
Ukuphucula ukusebenza kweNjini kunye neValve Springs
Kukho iindlela ezininzi zokunyusa imveliso ye-injini ngemithombo yevalvu.Nazi ezinye izicwangciso onokuthi uzisebenzise:
1. Ukuphucula i-valve spring
Enye yeendlela ezilula zokuphucula ukusebenza kwe-injini kukuphucula imithombo yevalve.Imithombo yevalve yokusebenza yomelele, ivumela injini ukuba isebenze kwi-rpm ephezulu, okukhokelela ekuphumeni kwamandla amaninzi.Ukuba uceba ukuphucula i-valve springs, qiniseka ukuba uhambelana ne-camshafts.
2. Lungisa ixesha levalvu
Enye indlela yokuphucula ukusebenza kwe-injini ngemithombo yevalve kukulungelelanisa ixesha levalvu.Ixesha le-valve lilawula ukuvulwa kunye nokuvalwa kweevalve kwaye imisela ukusebenza kwe-injini.Uhlengahlengiso lwexesha lunokunceda ukonyusa amandla kunye netorque ekusebenzeni ngcono kwenjini.
3. Faka icamshaft yokusebenza ephezulu
Ukufaka ii-camshafts ezisebenza kakhulu sesinye isicwangciso sokunyusa imveliso ye-injini ngokusebenzisa imithombo yevalvu.Iprofayile yecamshaft imisela ukunyuswa kwevalve kunye nobude, obuchaphazela ngokuthe ngqo ukuphuma kwamandla enjini.Ii-camshafts ezisebenza kakhulu zinokukhulula amandla angakumbi ehashe ngokuvumela umoya ongakumbi ungene enjinini.
4. Imikhwa elungileyo yokugcina
Okokugqibela, ukugcinwa kwemithombo yevalve kubalulekile ekuphuculeni ukusebenza kwe-injini.Ukuhlala ujonga izixhobo zevalvu ukuba zigugile kwaye uzitshintshe xa kukho imfuneko kunganceda ukuthintela umonakalo omkhulu we-injini.Ukongeza, ukugcina imithombo yevalve yakho icocekile kwaye igcobile inokwandisa ubomi babo kwaye iphucule ukusebenza.
ukuququmbela
Imithombo yevalvu idlala indima ebalulekileyo ekusebenzeni kwenjini.Ngophuculo oluchanekileyo kunye nezenzo zokulondoloza, zinokunceda ukwandisa ukuphuma kwamandla, ukwandisa ukusebenza kwe-injini kunye nokwandisa ubomi be-injini.Ngaphambi kokuphucula, qiniseka ukuba imithombo ye-valve ihambelana ne-camshafts kwaye ifakwe ngokweengcebiso zofakelo zomenzi.Ngokulandela ezi zicwangciso, unokuphucula ukusebenza kwe-injini yakho kwaye ufumane uhambo olulula.
