Yintoni igiya yeValve?

Ukuqonda Izixhobo zeValve: Ummangaliso woBunjineli

Izixhobo zevalvuyindlela ebalulekileyo kwiinjini zomphunga, enoxanduva lokulawula ixesha kunye nokuhamba kokungena komphunga kunye nokuphuma komoya kwiisilinda zenjini. Umsebenzi wayo ubalulekile ekwenzeni ngcono ukusebenza kakuhle, amandla, kunye nokuguquguquka kokusebenza koomatshini abasebenzisa umphunga. Ukusuka kwiinjini ezisebenza ngomphunga ukuya kwiinjini ezingasebenziyo, igiya yevalvu imele ukudibana okumangalisayo kokuchaneka koomatshini kunye nobuchule bobunjineli.

Iziseko zeValve Gear

Eyona njongo iphambili yezixhobo zevalvu kukulawula ukuhamba komphunga ngaphakathi nangaphandle kweesilinda zenjini. Oku kubandakanya imisebenzi emibini ebalulekileyo:

1. Ukungena ngomphunga: Ukuvula iivalvu ukuze umphunga oxinzelelweyo ungene kwisilinda, uqhuba i-piston.
2. I-Steam Exhaust: Ukuvula iivalvu ukuze kukhululwe umphunga osetyenzisiweyo, kulungiselela isilinda umjikelo olandelayo.

Ngokuvisisanisa ezi nkqubo, izixhobo zevalvu ziqinisekisa ukuba injini isebenza kakuhle kwaye inika amandla aphezulu.

Iintlobo zeeValve Gear

Kwiminyaka edlulileyo, kuye kwaveliswa uyilo oluninzi lwezixhobo zevalvu, nganye ineenzuzo ezikhethekileyo. Ezinye zezona ntlobo zibalaseleyo ziquka:

• Izixhobo zeStephenson Valve:Enye yezona ntlobo zokuqala nezisetyenziswa kakhulu, eyaziwa ngokulula kwayo nokuthembeka kwayo.
• Izixhobo zeValve yeWalschaerts:Isetyenziswa kakhulu kwiinjini zomoya, inika ulawulo oluchanekileyo kunye nokuncipha kokuguguleka kwezinto.
• Izixhobo zeValve yeBaker:Uyilo lwamva nje olususa iindawo ezityibilikayo, olubonelela ngenkqubo eqinileyo nesebenzayo ngakumbi.
• Izixhobo zeValve yeCaprotti:Inkqubo yevalvu yepoppet esetyenziswa kwiinjini zomphunga zanamhlanje, igxininisa ukusebenza kakuhle kunye nokugcinwa okuncinci.

Umvelisi weGear ye-Belon-i-Shanghai Belon Machinery Co., Ltd.

Iinkqubo zegiya zevalvu kwiinjini zomphunga zihlala zisebenzisa iigiya ze-spur okanye iigiya ze-bevel, kuxhomekeke kuyilo kunye nenjongo ethile:

1. IiSpur Gears

Izixhobo zeSpur zixhaphakile kwiindlela ezilula zegiya zevalvu apho amazinyo egiya ehambelana nomgca wegiya.
Isetyenziselwa ukudlulisa intshukumo phakathi kweeshafti ezihambelanayo kwiindlela zevalvu.
Zikhethwa ngenxa yokuba zilula ukwenziwa kwazo kunye nokudluliselwa kwentshukumo ngokuchanekileyo.
2. IiBevel Gears
Izixhobo zeBevelisetyenziswa xa intshukumo kufuneka idluliselwe phakathi kweeshafti nge-engile, ngokuqhelekileyo ingama-90 degrees.
Ifumaneka kwiindlela ezithile zoyilo lwegiya zevalvu, ingakumbi xa uyilo lwenjini lufuna ukuqondisa kwakhona intshukumo ye-angular.

3. IiGiya zeHelical(Azifumaneki lula kwiinkqubo zegiya zevalvu)

Ngamanye amaxesha isetyenziswa ukuze isebenze kakuhle kwaye ithule, kodwa ayixhaphakanga ngenxa yobunzima kunye neendleko.
Kwiimeko ezininzi, iigiya kwiinkqubo zegiya zevalvu zibeka phambili ukuqina nokuthembeka kunesantya, ngenxa yeemfuno zokusebenza kweenjini zomphunga.

Izinto ezisetyenziswayo kunye nokusebenza

Inkqubo eqhelekileyo yegiya yevalvu ibandakanya izinto ezininzi: iintonga ezingaqhelekanga, amakhonkco, iilever, kunye neevalvu ngokwazo. Ukunyakaza kwezi ndawo kuvela kwi-crankshaft yenjini okanye amavili okuqhuba, okuqinisekisa ukuhambelana ngokuchanekileyo nokuhamba kwepiston. Uhlengahlengiso kwixesha levalvu lunokwenziwa ukuze kulungiselelwe imithwalo eyahlukeneyo okanye iimeko zokusebenza, inkqubo eyaziwa ngokuba yi-"notching up" okanye "linking."

Indima ekuSebenzeni kakuhle nasekuSebenzeni kakuhle

Ivalvuizixhobo Ichaphazela kakhulu ukusebenza kakuhle kobushushu benjini. Ixesha elifanelekileyo linciphisa inkcitho yomphunga kwaye liqinisekisa ukuba injini isebenza ngaphakathi kwemilinganiselo yayo efanelekileyo. Iinjineli zihlala zizama useto lweevalvu ezahlukeneyo ukuze zikhuphe amandla amaninzi ngelixa zinciphisa ukusetyenziswa kwepetroli namanzi.

Ilifa kunye nokubaluleka kwanamhlanje

Nangona iinjini zomphunga zithathelwe indawo kakhulu ziinjini zomlilo zangaphakathi kunye neemoto zombane, izixhobo zevalvu zisaqhubeka ziyinto enomdla kwizifundo zolondolozo lwembali kunye nobunjineli. Iinjineli ezininzi zemveli kunye nabathandi bagcina eli lifa liphila ngokugcina nokubuyisela iinjini zomphunga ngeedizayini ezahlukeneyo zezixhobo zevalvu.
