Uma isivalo se-valve singaqinile noma i-sag inkulu kakhulu, i-valve idinga ukukhishwa ukuze ilungiswe, ilungiswe noma ishintshwe. Ukuze ukhiphe i-valve, qala ngokukhipha ikhava yekhanda le-cylinder, khipha i-valve rocker arm assembly, khipha ipayipi likaphethiloli elinomfutho ophezulu, khipha umjovo kaphethiloli, ukhulule inadi lekhanda le-cylinder, bese ukhipha ikhanda lesilinda. Bese ucindezela isihlalo se-valve spring ngethuluzi elikhethekile lokudiliza i-valve, cindezela iziphethu zangaphakathi nezangaphandle ze-valve, khipha isiqeshana sokukhiya i-valve, ngemva kokukhulula, susa iziphethu zangaphakathi nangaphandle ze-valve, bese i-valve ingakwazi. akhishwe. Ngemuva kokuthi i-valve isusiwe, kufanele imakwe futhi akufanele ishintshwe ngesikhathi sokuhlanganiswa. Usebenzisa inkomba yokudayela kanye nobakaki V, kala i-valve stem flex. Ngesikhathi sokuhlolwa, isiqu se-valve sisekelwa kumafreyimu amabili amise okwe-V anebanga elingu-100 mm, bese usebenzisa igeji yokudayela ukuze uhlole ukuthi u-1/2 wobude bevalvu uwukugoba. Uma yeqa umkhawulo ovumelekile, kufanele ilungiswe ngokucindezela ngesandla.
Lapho i-valve ivuza kancane, ingagaywa ukuze ibuyisele ukuqina kwayo. Ngaphambi kokugaya i-valve, i-valve, isihlalo se-valve kanye neshubhu eliqondisayo kufanele kuhlanzwe. Ngokukhetha, i-valve head subsidence yesilinda ngasinye kufanele ihambisane, futhi amamaki kufanele enziwe phezulu kwekhanda le-valve ukugwema ukudideka. Indlela yokugaya mathupha imi kanje:
(1) Faka isiphethu esithambile esiqwini sevalvu, gcoba ungqimba lwesihlabathi sevalvu emthambekeni wevalvu, gcoba amafutha okugcoba esiqwini sevalvu, bese ufaka ivalvu eshubhuni eliqondisayo. Isihlabathi se-valve sihlukaniswe izinhlobo ezimbili: isihlabathi esimahhadla nesihlabathi esihle. Ukukhethwa kuncike ezingeni lokushiswa kwe-valve bevel kanye ne-valve seat bevel. Ukuze ugaye ngokuqondile i-valve esetshenzisiwe, ungasebenzisa isihlabathi esimahhadla ukuze ugaye kuqala, bese usebenzisa isihlabathi esihle ukugaya kahle. Uma i-valve bevel ilungiswa ngokugaya okubushelelezi, isihlalo se-valve silungiswa ngokubuyisela kabusha, futhi i-bevel iphelile, ingagaywa kuphela ngesihlabathi esihle.
(2) Sebenzisa i-screwdriver yokugaya i-valve noma i-twister yerabha ukuzungezisa i-valve iye phambili naphambili (i-engeli yokuzungezisa kufanele ibe ngaphansi kuka-180°) ukuze ugaye. Phakathi nenqubo yokugaya, izenzo zokuphakamisa nokucindezela kufanele zenziwe eduze kwendawo ejikelezayo ye-valve ukushintsha indawo yokugijima ye-valve kanye nesihlalo sokuqinisekisa ukugaya okufanayo. Uma ugaya, ungasebenzisi amandla amakhulu, ungaphakamisi i-valve, futhi ushaye isihlalo se-valve ngamandla ukuze ugweme ukunweba i-bevel noma ukugaya ngaphandle kwemigodi e-concave.
(3) Uma ivalvu kanye nendawo eyehlelayo yesihlalo se-valve kugaywa kube yibhande le-annular eliphelele nelibushelelezi, kusho ukuthi ukugaya sekuqediwe. Isihlabathi se-valve singagezwa, futhi amafutha afakwe emthambekeni, bese egaywa imizuzu emi-3 kuya kwemi-5. Ngesikhathi sokugaya, ungasebenzisi isihlabathi se-valve esiningi kakhulu ukuze uvimbele ukulahleka nokuguga kwezinye izindawo zokukhwelana.
(4) Ithambeka elithinta phansi kufanele libe bushelelezi futhi lihlanzeke, futhi ububanzi bokuxhumana ngokuvamile bungu-1. 5 kuya ku-2. 0 mm. Beka i-valve esihlalweni se-valve efanayo, bese uthinta ikhanda le-valve izikhathi eziningana. Uma i-halo empunga eqhubekayo, ekhanyayo ivela phakathi nendawo yokusebenza ye-valve, kusho ukuthi i-valve ithintana okuvamile nesihlalo se-valve. Noma dweba umugqa wepensela othambile njalo ngo-4 mm endaweni yokusebenza ye-valve, bese ufaka i-valve kumhlahlandlela we-valve kanye nesihlalo se-valve, vula 1/8 ukuya ku-1/4 ukujika, noma uthephe izikhathi ezimbalwa, uma imigqa yepensela yonke iphakathi kwebhande Iphazamisekile, okubonisa ukuthi i-valve nesihlalo se-valve sivalwe kahle.
