Inowanikwa pamusoro peiyo valve system pamusoro pejini uye inoshandiswa kuvhara mavhavha uye mavhavha ekutyaira zvikamu kuti ive nechokwadi chekushanda kwakajairika kwevhavha system. Basa guru revhavha yevhavha rinosanganisira kuchengetedza hurongwa hwevhavha yakachena uye kudzivirira kusvibiswa kwakadai seguruva, tsvina, marara kubva pakupinda muvharovha system, nokudaro kudzivirira zvikamu zvevhavha yevhavha uye mabheji evhavha. Pamusoro pezvo, chivharo chevhavha chinovimbisa kuti mafuta haabvire kana kupinda muvharuvhu inotakura, kudzivirira kukuvara kwechikamu uye tsvina yemafuta.
Chimiro chechivharo chevhavha chinosanganisira muviri wevharuvhu, chivharo chevhavha, chivharo chevhavha, kurongedza, bhaudhi, nati, gasket, mubato, kutakura uye mudziyo wekutyaira. Muviri wevharuvhu ndiyo huru yekusimbisa chimiro, uye chivharo chevhavha chiri pamusoro pemuviri wevharuvhu kuti chivhare uye ubate kurongedza kana spool. Iyo spool chikamu chekutonga chinogadzirisa mafambiro ekuyerera, kumanikidza uye kuyerera kwemvura. Iko kurongedza kunowanikwa pakati pe spool nebhoneti kuvhara uye kuderedza kuvuza. Mabhaudhi nenzungu zvinoshandiswa kubatanidza muviri wevharuvhu kubhoneti kuti uibate pamwechete. Iyo gasket inogara pakati pebhaudhi uye nati uye inodzivirira muviri uye cap kubva pakupfeka. Mubato unoshandiswa kushandisa vharafu, iyo inotakura inotsigira spool uye inoderedza kupokana, uye mudziyo wekutyaira unoshandiswa kutyaira spool kufamba kuti uwane kutonga kwevhavha .
Kugadziriswa kwevhavha yevhavha uye kutsiva kwakakoshawo. Kugara uchiongorora uye kugadzirisa kunogona kudzivirira matambudziko anokonzerwa neakasununguka mavharuvha caps kana kusavharika chisimbiso. Kuiswa kwakashata kunogona kukonzera kutadza kwevhavha, izvo zvinogona kukanganisa injini uye hupenyu. Kana uchitsiva bhoneti, zvinhu zvakafanana uye saizi seyekutanga chikamu chinofanira kushandiswa kuve nechokwadi chekushanda kwakakodzera kweinjini.
Basa guru revhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhachivhachivhachivhachivhachivhachichivhachivhachivhachivhachichinzvimbo mativi:
Chisimbiso nekudzivirira : chivharo chevhavha chinoshandiswa kuvhara hurongwa hwevhavha kudzivirira guruva, tsvina, marara uye kumwe kusvibiswa kupinda muvharuvhu, nekudaro kudzivirira zvikamu zvevhavhavha uye mabheji evhavha, uye nekuona nzvimbo yakanaka yekushanda yeinjini. zvikamu zvemukati.
Kudzora uye kudzivirira guruva : Iyo yevhavha yevhavha inowanzo gadzira yakavharwa yakazara nezvikamu zvese zveinjini kuti ive nechokwadi chekuzora uye kuchengetedzwa kwemukati mejini. Kuiswa chisimbiso chayo kwakakosha kune yakajairika kushanda kweinjini, lubrication, dziviriro nekudzivirira guruva.
Gadzirisa crankcase ventilation : Mune zvimwe zviitiko, chivharo cheValve chinewo Positive Crankcase Ventilation Valve (PCV), ine basa rekudzora huwandu hwehutsi hwemafuta hunogadzirwa ne crankcase ventilation system mu system yekudya, uye kugura mhepo. kana injini iri kupisa kudzivirira kutadza sekuputika kwecrankcase.
Material options : Mavhavhavha anovhara anowanzo gadzirwa nesimbi, zvinhu zvakajairika zvinosanganisira aruminiyamu alloy uye simbi yakakandwa. Aluminium alloy valve mavhavha akareruka uye ane yakanaka kupisa conductivity, nepo cast iron mavharuvhu anovhara ane simba repamusoro uye kusimba.
Kugadzirisa uye kutsiva kurudziro : Mavhavha anovhara anoda kugara achiongororwa uye kugadzirisa, kunyanya kutarisa kusimba kwavo uye kuisirwa. Kana chivharo chevhavha chakasununguka kana chisina kuvharwa zvakanaka, chinogona kutungamirira kukukundikana kwevhavha, izvo zvinokanganisa kushanda uye hupenyu hwejini. Kana uchitsiva bhoneti, zvinhu zvakafanana uye saizi seyekutanga chikamu chinofanira kushandiswa kuve nechokwadi chekushanda kwakakodzera kweinjini.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pathiri saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
