Yintoni i-varia yevali?

Ukuqonda i-valve gear: Ummangaliso wobunjineli

I-varYindlela ebalulekileyo kwiinjini ze-Steam, enoxanduva lokulawula ixesha lokwamkelwa kwe-Steam kunye nokuphelisa iisilinda ze-injini. Umsebenzi wayo kubaluleke kakhulu ekusebenzeni kakuhle, amandla, kunye nokusebenza ngokugungqayo kumatshini onamandla anamandla. Ukusuka kwi-Locomotives ukuya kwiinjini zamaThosi, i-Valve Gear imele i-insocing enomdla yobume boomatshini kunye nokudityaniswa kobunjineli.

Iziseko zegesi yevali

Eyona njongo iphambili yegiya yevali kukulawula ukuhamba kwe-steam ngaphakathi nangaphandle kweesilinda zenjini. Oku kubandakanya imisebenzi emibini ephambili:

1. Ukwamkelwa kweSteam: ukuvula i-valves ukuvumela i-steam-surd steam yokufaka isilinda, ukuqhuba ipiston.
2. Ukuphelisa i-Steam

Ngokuvumelanisa ezi nkqubo, igiya yevali iqinisekisa ukuba i-injini isebenza ngokufanelekileyo kwaye ihambisa amandla amakhulu.

Iindidi zegiya yevali

Kwiminyaka edlulileyo, kuye kwaphuhliswa uloyiso lweegiya zevali, nganye inikela izibonelelo ezizodwa. Ezinye zeentlobo eziphambili zibandakanya:

• I-Stephenson Valve Gear:Enye yezona ntlobo zisetyenzisiweyo, ezaziwa ngokuba zilula kunye nokunyaniseka.
• I-Walschaert Valve Gear:Isetyenziswe ngokubanzi kwi-locomotives, inika ulawulo oluchanekileyo kwaye incitshiswe i-subse kumacandelo.
• I-Baker Valve Gear:Uyilo lwamva olushenxisa iinxalenye ezityibilikayo, ukubonelela ngenkqubo eyomeleleyo nenempumelelo.
• I-Caprotti Valve Gear:Inkqubo yeVoppet Valvet esetyenziswe kwezinye iinjini zanamhlanje zanamhlanje, igxininisa ukusebenza kakuhle kunye nokulungiswa okuncitshisiweyo. I-pipeling valves yegiya

I-Gear yeGear Gear yeGear Gear - Shanghai Viesry Co., Ltd.

Iinkqubo zeValve Gear kwiinjini zeSteam zihlala zisebenzisa iigiya ze-spur okanye i-bevel gela, kuxhomekeke kuyilo oluthile kunye nenjongo:

I-1. I-Spur Gears

Igiya ye-spur Iqhelekile kwiindlela zeValve ezilula apho amazinyo egiya ahambelana khona kwi-axis yegiya.
Isetyenziselwa ukuhambisa intshukumo phakathi kwe-shafts ehambelana neendlela zeValve.
Bakhetha ukukhululeka kwabo ekunikezelweni kwemveliso kunye nosulelo oluchanekileyo.
I-2. Iibhiya ze-bevel
I-Bevel gearisetyenziswe xa intshukumo kufuneka idluliselwe phakathi kwe-shafts kwi-engile, iqhelekile i-90 degrees.
Ifunyenwe kwii-vali ze-vali ye-vaar ye-vaar, ngakumbi xa ubume beinjini bufuna i-Anglar Recrecietion.

I-3. I-helilicalge(Inqabile kwi-valve gear)

Ngamaxesha athile isetyenziselwa ukuSebenza kunye nokuSebenza ngokuQhelekileyo, kodwa kuncinci ngenxa yobunzima kunye neendleko.
Kwiimeko ezininzi, iigiya kwiinkqubo zeValve Gear zibeka phambili ukuqina kunye nokuthembeka ngaphezulu kwesantya, kunikwe iimfuno zomsebenzi weenjini zeSteam.

Izinto kunye nokusebenza

Inkqubo yesiqhelo ye-vali ye-vali ye-vali ibandakanya izinto ezininzi: Iintonga ze-eccentric, amakhonkco, i-levers, kunye nezivelisi. Isindululo sala macandelo sivela kwii-cranksshaft okanye iivili zokuqhuba, ukuqinisekisa ungqamo oluchanekileyo kunye nentshukumo yepiston. Uhlengahlengiso kwixesha leValve lunokwenziwa ukulungiselela imithwalo eyahlukeneyo okanye iimeko zokusebenza, inkqubo eyaziwa ngokuba "kukungasebenzi" okanye "ukudibanisa."

Indima ekusebenzeni kakuhle kunye nokuSebenza

Ivalveigiya Impembelelo ikakhulu impembelelo ye-injini ye-injini ye-injini. Ixesha elifanelekileyo lokuthatha ixesha linciphisa i-steam inkcitho kwaye iqinisekise ukuba i-injini isebenza ngaphakathi kweparameter yayo efanelekileyo. Iinjineli zihlala zivavanya useto olwahlukileyo lwe-valve ukwandisa igalelo lamandla ngelixa kuncitshiswa ukusetyenziswa kwepetroli kunye nokusetyenziswa kwamanzi.

Ilifa kunye nokuThelwa kwanamhlanje

Ngelixa iinjini ze-Steam zithathelwe indawo yinjini yangaphakathi yokudibana kunye neemoto zombane, i-vaar yevar ihleli ingumdla kwizifundo zembali kunye nezifundo zobunjineli. Uninzi lwelifa lemveli kunye nenzondelelo igcina ifa liphila ngokugcina nokubuyisela i-locomotives ye-steam enamabala ahlukeneyo evalve.
