Valve iav yog dab tsi?

Nkag siab Valve Iav: Ib qho Engineering Marvel

Valve iavyog ib qho tseem ceeb mechanism nyob rau hauv chav cav, lub luag hauj lwm rau kev tswj lub sij hawm thiab txav ntawm chav nkag thiab tso pa tawm hauv lub cav lub tog raj kheej. Nws muaj nuj nqi yog qhov tseem ceeb rau optimizing efficiency, lub zog, thiab ua hauj lwm smoothness nyob rau hauv lub chav-powered machinery. Los ntawm locomotives mus rau qhov chaw nres tsheb, lub iav iav sawv cev rau kev sib tshuam zoo nkauj ntawm cov neeg kho tshuab precision thiab engineering innovation.

Lub hauv paus ntawm Valve Iav

Lub hom phiaj tseem ceeb ntawm lub valve iav yog los tswj qhov ntws ntawm cov pa mus rau hauv thiab tawm ntawm lub cav lub tog raj kheej. Qhov no suav nrog ob txoj haujlwm tseem ceeb:

1. Steam Admissions: Qhib cov li qub kom tso cai rau lub zog siab kom nkag mus rau lub tog raj kheej, tsav lub piston.
2. Chav Dej: Qhib cov li qub kom tso cov pa siv, npaj lub tog raj kheej rau lub voj voog tom ntej.

Los ntawm synchronizing cov txheej txheem no, lub iav iav kom ntseeg tau tias lub cav ua haujlwm tau zoo thiab muab lub zog siab tshaj plaws.

Hom Valve Iav

Tau ntau xyoo, ntau qhov kev tsim ntawm lub valve iav tau tsim, txhua qhov muab qhov tshwj xeeb zoo. Qee yam tseem ceeb tshaj plaws muaj xws li:

• Stephenson Valve Iav:Ib qho ntawm thawj thiab feem ntau siv hom, paub txog nws txoj kev yooj yim thiab kev ntseeg tau.
• Walschaerts Valve Iav:Dav siv nyob rau hauv locomotives, muab meej tswj thiab txo hnav ntawm cov khoom.
• Baker Valve Iav:Ib qho kev tsim tom qab uas tshem tawm cov zawv zawg qhov chaw, muab lub zog ruaj khov thiab ua haujlwm tau zoo.
• Caprotti Valve Iav:Lub poppet valve system siv nyob rau hauv ib co niaj hnub chav cav, hais txog efficiency thiab txo tus txij nkawm. pipeline valve iav

Tuam Tshoj Customized Gearbox Chaw tsim tshuaj paus - Shanghai Belon Machinery Co., Ltd.

Valve iav systems nyob rau hauv chav cav feem ntau siv spur iav los yog bevel iav, nyob ntawm seb tus qauv tsim thiab lub hom phiaj:

1. Spur Gears

Spur iav feem ntau nyob rau hauv yooj yim valve iav mechanisms qhov twg cov iav hniav yog parallel rau lub iav axis.
Siv rau kev xa cov lus tsa suab ntawm qhov sib npaug ntawm cov ncej hauv valve mechanisms.
Txaus siab rau lawv qhov yooj yim ntawm kev tsim khoom thiab kev sib kis tau yooj yim.
2. Bevel Gears
Bevel iavsiv thaum cov lus tsa suab yuav tsum tau kis ntawm shafts ntawm lub kaum sab xis, feem ntau 90 degrees.
Pom muaj nyob rau hauv qee qhov valve iav tsim, tshwj xeeb tshaj yog thaum lub cav layout xav tau angular motion redirection.

3. Helical Gears(Tsis tshua muaj nyob rau hauv valve gear systems)

Qee zaum siv rau kev ua haujlwm smoother thiab ntsiag to, tab sis tsawg dua vim qhov nyuaj thiab tus nqi.
Feem ntau, lub zog nyob rau hauv lub valve iav qhov tseem ceeb ntawm kev ua haujlwm ntev thiab kev ntseeg siab tshaj qhov nrawm, muab cov kev xav tau ntawm cov tshuab ua haujlwm.

Cheebtsam thiab kev ua haujlwm

Ib tug raug valve iav system muaj xws li ob peb yam khoom: eccentric rods, txuas, levers, thiab li qub lawv tus kheej. Lub zog ntawm cov khoom no yog muab los ntawm lub cav lub crankshaft los yog tsav lub log, kom ntseeg tau meej synchronization nrog lub piston lub zog. Kev hloov pauv hauv lub sijhawm lub sijhawm tseem tuaj yeem ua kom haum rau qhov sib txawv ntawm cov khoom thauj lossis kev ua haujlwm, txheej txheem hu ua "notching up" lossis "linking."

Lub luag haujlwm hauv Kev Ua Haujlwm thiab Kev Ua Haujlwm

Valveiav cuam ​​tshuam rau lub cav lub thermal efficiency. Lub sij hawm tsim nyog minimizes chav khib nyiab thiab xyuas kom meej tias lub cav ua haujlwm hauv nws qhov kev pom zoo. Cov kws tshaj lij feem ntau sim nrog qhov sib txawv ntawm qhov sib txawv kom ua kom lub zog tso zis ntau tshaj thaum txo cov roj thiab dej siv.

Txoj cai thiab niaj hnub cuam tshuam

Thaum lub tshuab hluav taws xob tau hloov pauv los ntawm cov tshuab hluav taws xob sab hauv thiab cov tshuab hluav taws xob, cov iav iav tseem yog ib qho kev txaus siab hauv keeb kwm kev khaws cia thiab kev tshawb fawb engineering. Ntau cov cuab yeej cuab tam txoj kev tsheb ciav hlau thiab cov neeg nyiam ua kom lub neej qub txeeg qub teg los ntawm kev tswj hwm thiab kho cov kav hlau txais xov nrog ntau yam valve iav tsim.
