Ho Utloisisa Lisebelisoa tsa Valve: Ntho e Hlollang ea Boenjiniere

Lisebelisoa tsa valveke mokhoa oa bohlokoa oa lienjine tsa mouoane, o ikarabellang ho laola nako le motsamao oa ho kena ha mouoane le mosi oa mouoane ka har'a lisilindara tsa enjene. Mosebetsi oa eona o bohlokoa bakeng sa ho ntlafatsa ts'ebetso, matla, le boreleli ba ts'ebetso mochining o tsamaeang ka mouoane. Ho tloha ho li-locomotive ho ea ho lienjine tse emeng, lisebelisoa tsa li-valve li emela mateano a makatsang a ho nepahala ha mochini le boqapi ba boenjiniere.

Lintho tsa Motheo tsa Li-valve Gear

Sepheo se seholo sa lisebelisoa tsa valve ke ho laola ho phalla ha mouoane ho kena le ho tsoa ka har'a lisilindara tsa enjene. Sena se kenyelletsa lits'ebetso tse peli tsa bohlokoa:

1. Kamohelo ea Mouoane: Ho bula li-valve ho lumella mouoane o nang le khatello e phahameng hore o kene ka silindara, o khanna piston.
2. Mouoane oa Mouoane: Ho bula li-valve ho lokolla mouoane o felileng, ho lokisa moqomo bakeng sa potoloho e latelang.

Ka ho hokahanya lits'ebetso tsena, lisebelisoa tsa li-valve li netefatsa hore enjene e sebetsa hantle ebile e fana ka matla a mangata.

Ho theosa le lilemo, ho qapiloe meralo e mengata ea lisebelisoa tsa li-valve, e 'ngoe le e' ngoe e fana ka melemo e ikhethang. E meng ea mefuta e tsebahalang haholo e kenyelletsa:

• Stephenson Valve Gear:E 'ngoe ea mefuta ea khale ka ho fetisisa le e sebelisoang ka ho fetisisa, e tsejoang ka ho ba bonolo le ho tšepahala.
• Lisebelisoa tsa Valve tsa Walschaerts:E sebelisoa haholo ho li-locomotives, e fanang ka taolo e nepahetseng le ho fokotsoa ho senyeha ha likarolo.
• Sesebelisoa sa Baker Valve:Moralo oa morao-rao o felisang likarolo tse thellang, o fana ka sistimi e tšoarellang le e sebetsang hantle.
• Sesebelisoa sa Valve ea Caprotti:Sistimi ea li-valve tsa poppet e sebelisoang lienjineng tse ling tsa sejoale-joale tsa mouoane, e totobatsang katleho le tlhokomelo e fokotsehileng. lisebelisoa tsa li-valve tsa pipeline

Sistimi ea lisebelisoa tsa li-valve lienjineng tsa mouoane hangata li sebelisa likere tsa spur kapa likere tsa bevel, ho latela moralo le sepheo se itseng:

1. Spur Gears

Hlahisa lisebelisoa e tloaelehileng mecheng e bonolo ea li-valve moo meno a gear a bapileng le axis ea gear.
E sebelisetsoa ho fetisa motsamao lipakeng tsa li-shafts tse bapileng mecheng ea li-valve.
E ratoa bakeng sa boiketlo ba bona ba ho etsa tlhahiso le phetiso e nepahetseng ea motsamao.
2. Bevel Gears
Lisebelisoa tsa bevele sebelisoa ha motsamao o hloka ho fetisoa lipakeng tsa li-shafts ka lehlakoreng, hangata likhato tse 90.
E fumaneha ka meralo e itseng ea li-valve, haholo ha sebopeho sa enjene se hloka hore ho be le motsamao o mong oa angular.

3. Helical Gears(Ha hoa tloaeleha ho li-valve gear system)

E sebelisoa ka linako tse ling bakeng sa ts'ebetso e bonolo le e khutsitseng, empa e sa tloaelehe ka lebaka la ho rarahana le litšenyehelo.
Maemong a mangata, likere tsa sistimi ea li-valve li etelletsa pele ho tšoarella le ho ts'epahala ho feta lebelo, ho latela litlhoko tsa ts'ebetso ea lienjineri tsa mouoane.

Likaroloana le Ts'ebetso

Sistimi e tloaelehileng ea li-valve e kenyelletsa likarolo tse 'maloa: lithupa tsa eccentric, likhokahano, li-levers le li-valve ka botsona. Ho sisinyeha ha likarolo tsena ho tsoa ho crankshaft ea enjene kapa mabili a ho khanna, ho netefatsa hore ho na le khokahano e nepahetseng le motsamao oa piston. Litokiso mabapi le nako ea li-valve li ka boela tsa etsoa ho amohela meroalo e fapaneng kapa maemo a ts'ebetso, ts'ebetso e tsejoang e le "notching up" kapa "linking."

Seabe sa ho Sebetsa ka Bokhabane le ho Tšebetso

Seqhubulisebelisoa e ama haholo ho sebetsa hantle ha mocheso oa enjene. Nako e nepahetseng e fokotsa tšenyo ea mouoane 'me e etsa bonnete ba hore enjene e sebetsa ka har'a maemo a eona a nepahetseng. Hangata lienjiniere li leka li-valve tse fapaneng ho eketsa tlhahiso ea matla ha li ntse li fokotsa tšebeliso ea mafura le metsi.

Lefa le Bohlokoa ba Kajeno

Leha lienjineri tsa mouoane li nketsoe sebaka haholo ke lienjineri tse tukang ka hare le li-motor tsa motlakase, lisebelisoa tsa li-valve e ntse e le taba ea thahasello lithutong tsa paballo ea nalane le boenjiniere. Literene tse ngata tsa khale le ba chesehelang ho boloka lefa le phela ka ho boloka le ho khutlisetsa literene tsa mouoane ka meralo e fapaneng ea li-valve.
