Iyini i-gasket yekhava yegumbi le-valve yemoto
I-automotive valve chamber gasket, eyaziwa nangokuthi i-valve chamber cover gasket, iyingxenye ebalulekile yokuvala ngaphakathi kwenjini, etholakala kukhava yegumbi lama-valve, umsebenzi wayo oyinhloko ukuvimbela igesi yegumbi elivuthayo nesipholile ukuthi singangeni ku-crankcase. Le gasket ivame ukwenziwa ngerabha, inokunwebeka okuhle nokumelana nokugqokwa, ingagcina umphumela wokuvala izinga lokushisa eliphakeme, ukucindezela okuphezulu kanye nendawo egqwala kawoyela negesi.
Umsebenzi we-valve chamber cover gasket
umsebenzi wokuvala : umsebenzi oyinhloko we-valve cover gasket ukuvala igebe phakathi kwegumbi le-valve yenjini nekhanda lesilinda ukuvimbela ukuvuza kwegesi evuthayo namafutha okugcoba. Iqinisekisa ukucinana kwangaphakathi kwenjini futhi ivimbela igesi nesipholile ukuthi singangeni ku-crankcase.
vimbela ukuvuza kukawoyela : uma i-gasket yekhava yevalvu ivuza, kuzobangela ukuqina komoya wenjini, okuzophazamisa ukusebenza kwenjini, futhi kuholele nasekulahlekeni kwenjini ezimeni ezimbi kakhulu.
Iziphakamiso zokushintshwa nokulungiswa
Ukuhlola okuvamile : Ngenxa yokuthi i-valve cover gasket isebenza ezindaweni ezishisayo nezinomfutho ophezulu, kulula ukuguga, ngakho idinga ukuhlolwa njalo nokushintshwa ukuze kuqinisekiswe ukusebenza okuvamile kwenjini.
Inqubo yokushintsha : Ukuze umiselele i-gasket yekhava ye-valve, susa izikulufu zekhava ye-valve ngokuzungeza kuzo zombili izinhlangothi, ukhulule isembozo se-valve ngommese oqondile, bese ukhipha i-gasket yekhava ye-valve. Bese uhlanza indawo yokuxhumana phakathi kwesembozo segumbi le-valve nekhanda lesilinda nge-ejenti yokuhlanza. Ngaphambi kokufaka i-gasket yekhava ye-valve entsha, sebenzisa i-sealant bese uqinisa izikulufu ngokudayagonali ukusuka maphakathi kuya kuzo zombili izinhlangothi .
Ngokuhlola njalo nokugcina i-gasket yekhava ye-valve, impilo yesevisi yenjini inganwetshwa ngokuphumelelayo ukuze kuqinisekiswe ukusebenza kwayo okuvamile.
Umsebenzi oyinhloko we-gasket yekhava yegumbi lama-valve ukuqinisekisa ukucinana kwegumbi le-valve nokuvimbela uwoyela nolunye uketshezi ukuthi lungavuzi. I-gasket ye-valve chamber itholakala phezulu enjinini, exhunywe ku-cylinder head kanye nesembozo se-valve mechanism, futhi imisebenzi yayo eyinhloko ihlanganisa:
Umsebenzi wokuvala : i-gasket yekhava ye-valve ingavala igebe phakathi kwegumbi le-valve yenjini kanye nekhanda lesilinda ukuvimbela ukuvuza kwegesi evuthayo namafutha okugcoba. Iqinisekisa ukuqina kwegumbi le-valve, ivimbela ukuvuza kwamafutha futhi igcine uphawu lwegumbi le-valve.
uthuli nokugcobisa : i-gasket ye-valve chamber ayivimbi nje kuphela ukuvuza kukawoyela, kodwa futhi idlala indima yokuvikela uthuli ukuvikela izingxenye zangaphakathi zenjini othulini nokunye ukungcola. Ngesikhathi esifanayo, iqinisekisa ukusebenza kahle kwesakhiwo se-valve yenjini kanye nokugcotshwa okwanele.
kuvimbela ukunukubezeka kwemvelo : uma i-valve cover gasket ihluleka, uwoyela ungase uvuze futhi uconsele emgwaqeni, okubangele ukungcoliswa kwemvelo futhi kwandise nobunzima bokuhlanza.
Izinto kanye nomjikelezo wokushintsha
Ama-gaskets ekhava yegumbi lama-valve, ngokuvamile enziwe ngenjoloba, azoqina ngenxa yokuguga ngemva kwesikhathi eside esetshenziswa, okuholela ekunciphiseni kokusebenza kokuvala, okuholela ekuvuzeni kukawoyela. Ngaphezu kwalokho, ukucindezela kwesikulufu esingalingani, ukuwohloka kwe-gasket, ukuvinjwa kwevalvu yokungenisa umoya ye-crankcase nezinye izici nakho kungaholela ekuphumeni kukawoyela.
Iziphakamiso zokushintshwa nokulungiswa
Ukushintsha i-gasket yekhava ye-valve kuwumsebenzi ovamile wokulungisa futhi ngokuvamile akudingi ukulungiswa okukhulu, ukufaka esikhundleni se-gasket evuzayo uwoyela. Ngesikhathi sokushintshwa, kuyadingeka ukuhlanza ubuso bekhava ye-valve kanye nekhanda le-cylinder, bese ufaka i-gasket entsha futhi uqinisekise ukuthi ifakwe endaweni efanele kanye nobukhulu ukuze kuqinisekiswe ukuvaleka okuhle.
