Iyini indima ye-automobile valve seal
Indima eyinhloko yophawu lwe-valve yemoto ukuqinisekisa ukuxhumana phakathi kwe-valve nesihlalo se-valve ukuvimbela ukuvuza kwegesi, ukuze kuqinisekiswe ukusebenza okuvamile nokusebenza kwenjini. .
Ama-valve avalwe kahle angabangela izinkinga ezihlukahlukene, okuhlanganisa:
Ukuwohloka kokusebenza : ukungavali kahle kwe-valve kuzoholela ekuvuzeni komoya, kuthinte ukusebenza okuvamile kwenjini, bese kunciphisa ukusebenza kwemoto iyonke.
ukwehluleka komshini : ukuxega isikhathi eside kungaholela ekwenyukeni kokuguga kwesihlalo se-valve, futhi kuholele nasekuhlulekeni kwemishini okubi kakhulu.
ukwanda kokusetshenziswa kukaphethiloli : ukuvuza komoya kuzoholela ekushiseni okungaphelele, kwandise ukusetshenziswa kukaphethiloli, kwehlise ukonga kukaphethiloli.
Inkinga ye-emission : I-lax seal ingathinta izilawuli zokukhishwa futhi ingase ibangele ukukhishwa kwekhabhoni okweqile.
Ukuze kuqinisekiswe ukuqina kwe-valve, izinyathelo ezilandelayo zingathathwa:
Ukusetshenziswa kwezinto ezisezingeni eliphezulu kanye nobuchwepheshe bokunemba kwemishini : Izinto ze-valve zekhwalithi ephezulu kanye nobuchwepheshe bokunemba bomshini kunganciphisa igebe phakathi kwe-valve nesihlalo se-valve, kuthuthukise ukuvala.
ukugcinwa okuvamile nokushintshwa kwezingxenye ezigugile : ukushintshwa ngesikhathi kwezigxivizo zikawoyela we-valve ezigugile nezinye izimpawu ukuvimbela uwoyela ukuthi ungangeni egunjini lama-valve, okuthinta umphumela wokuvala ama-valve.
ukufakwa nokulungiswa okulungile : ukuqinisekisa ukuthi intwasahlobo ye-valve spring ifaka ngokusesilinganisweni nangokufanele, ukugwema ngenxa yokunganeli kwentwasahlobo yasentwasahlobo noma ukufakwa ngendlela engafanele okubangelwa ukuvaleka okuxekethile.
I-automotive valve seal isho ikhono levalvu ukugcina uketshezi oluphakathi nendawo ukuthi lungagelezi lapho luvaliwe. Ama-valve seal angahlukaniswa ngokuya ngokuma nendawo yendawo yokuvala kanye nesiqondiso sokugeleza okuphakathi, ikakhulukazi ihlukaniswe ngezinhlobo ezilandelayo:
I-Metal seal : Ukusetshenziswa kwe-deformation yemishini kanye ne-plastic deformation phakathi kwezindawo zensimbi ukuze kuvalwe i-valve, efanelekile izinga lokushisa eliphezulu kanye nezikhathi zokucindezela okukhulu.
soft seal : Ukusetshenziswa kwezinto zokufaka ugesi, irabha, ipulasitiki nezinye izinto eziguquguqukayo njengezingxenye zokuvala, ezifanele ukusetshenziswa kwengcindezi ephansi, njengemboni yamakhemikhali kanye nemboni yezokwelapha.
Umkhono we-sleeve seal : uphawu olusebenza ngomshini, olufanele izinga lokushisa eliphezulu nokucindezela noma ngemidiya egqwalayo.
Ukuhlolwa kokusebenza kokuvalwa kwe-valve
Ukuze kuqinisekiswe ukusebenza kokuvala kwe-valve, ukuhlolwa okuhambisanayo kufanele kwenziwe, ikakhulukazi okuhlanganisa:
Ukuhlolwa kokuqina komoya : Hlola ukuthi ingabe kukhona ukuvuza ngokugcwalisa ingcindezi ethile yegesi kuvalvu.
ukuhlolwa kokuqina koketshezi : Gcwalisa i-valve ngomfutho othile woketshezi ukuze uhlole ukuthi akukho yini ukuvuza kanye nebanga lokuvala levalvu.
ukuhlolwa kwamandla : hlola amandla acindezelayo kanye nomthamo wokuthwala wevalvu ukuze uqinisekise ukuthi angeke wonakaliswe izinkinga zezinto ezibonakalayo.
Ukuthuthukiswa kobuchwepheshe bokuvalwa kwe-valve
Ubuchwepheshe bokuvalwa kwe-valve ikakhulukazi buhlanganisa ukuvala isihlalo kanye nokuvala ama-disc izingxenye ezimbili. Eminyakeni yamuva, ngenqubekelaphambili yesayensi yezinto ezibonakalayo, ukucubungula ubuchwepheshe kanye nomqondo wokuklama, ubuchwepheshe bokuvalwa kwama-valve buye benza inqubekelaphambili emangalisayo. Ukusetshenziswa kwezinto ezintsha zokuvala ezifana ne-polytetrafluoroethylene (PTFE), i-polyurethane, i-polyformaldehyde nezinye izinto ze-polymer, kanye nokwenza kahle kokwakhiwa kwesakhiwo sokubeka uphawu kanye nokusetshenziswa kobuchwepheshe bokulawula obuhlakaniphile, kwenza ukusebenza kokuvalwa kwe-valve kube ngcono kakhulu.
