Iyini ikhava ye-valve yemoto
I-automotive chamber cover pad, eyaziwa nangokuthi i-valve chamber cover pad, iyingxenye ebalulekile yokuvala ngaphakathi kwenjini. Itholakala kukhava yegumbi le-valve, futhi umsebenzi wayo oyinhloko ukuvimbela igesi kanye nesipholile esisegunjini lomlilo ukuba singangeni ku-crankcase nokuqinisekisa ukucinana kwenjini ngaphakathi. I-gasket ye-valve chamber cover ngokuvamile yenziwa ngenjoloba, inokunwebeka okuhle nokumelana nokugqokwa, ingasebenza endaweni yokushisa ephezulu, umfutho ophezulu kanye nemvelo yokugqwala kukawoyela negesi.
I-valve cover pad ingaphansi kwengcindezi enkulu kanye nokugqwala ngesikhathi sokusebenza kwenjini, ngakho-ke idinga ukubhekwa futhi ishintshwe njalo ukuze kuqinisekiswe ukusebenza okuvamile nokusebenza kwenjini. Ngokukhula kwesikhathi sokusetshenziswa, ikhava yegumbi le-valve ingase ibonakale iguga, iqina, i-deformation nezinye izinkinga, okuholela ekunciphiseni kokusebenza kokuvala, okuthinta ukusebenza okuvamile kwenjini. Ngakho-ke, umnikazi kufanele ahlole futhi ashintshe ikhava yegumbi le-valve njengengxenye ebalulekile yokulungiswa kwenjini.
Izinto ze-valve cover pad nazo zithinta impilo yayo yesevisi. Kukhona izinto ezimbili ezibalulekile emakethe: izinto zenjoloba kanye nenhlanganisela. I-valve ye-rubber cover pad ivamile, kodwa kulula ukuguga. Iphedi yekhava yegumbi le-valve ehlanganisiwe inokuqina okungcono nokumelana nokugqoka. Umnikazi kufanele akhethe okokusebenza okufanele ngokuya ngokusetshenziswa okuthile kwemoto kanye nesincomo somkhiqizi sokwelula impilo yayo yesevisi.
Umsebenzi oyinhloko wephedi yekhava yegumbi le-valve (iphedi yekhava yegumbi le-valve) ukuqinisekisa ukucinana kwegumbi le-valve nokuvimbela ukuvuza kwamafutha. Ixhunywe nekhanda le-cylinder kanye nesembozo se-valve phezulu ukuze kuqinisekiswe ukusebenza kahle nokugcotshwa okuphelele kwesakhiwo se-valve yenjini, kuyilapho idlala indima ebalulekile ekuvimbeleni uthuli nokuvala.
Amaphedi ekhava egumbi lamavalvu ngokuvamile enziwa ngerabha futhi angase abe lukhuni ngokukhula ngemva kokusetshenziswa isikhathi eside, okuholela ekuvuzeni kukawoyela. Ngaphezu kwalokho, ukucindezela kwesikulufu esingalingani, ukucindezela kwesikulufu ngokweqile, ukuwohloka kwe-valve ye-gasket, ukuvinjwa kwe-valve yokungenisa umoya nge-crankcase, indandatho yokuvala noma izinkinga zekhwalithi ye-sealant kungaholela kuwoyela we-valve we-gasket .
Amafutha aphumayo angase akhanywe embozweni yegumbi lamavalvu, avimbe indlela kawoyela futhi aphazamise ukusebenza okuvamile kwenjini. Ukuvuza kukawoyela isikhathi eside kuzoholela ekuntulekeni kokugcotshwa kukawoyela ezingxenyeni zangaphakathi zenjini, kubhebhethekise ukuguga, futhi kungaholela ekulahlekeni kwenjini ezimeni ezibucayi.
Ngakho-ke, lapho i-gasket yekhava yegumbi le-valve itholakala iwuwoyela ovuzayo, i-gasket kufanele ishintshwe kusenesikhathi ukuze kuxazululwe inkinga yokuvuza kukawoyela, kuqinisekiswe ukusebenza okujwayelekile kwenjini futhi kunwetshwe impilo yesevisi.
