Dab tsi yog lub valve iav?

Nkag siab Valve Gartica: Ib Lub Tshuab Marvel

Phab Hlau Iavyog ib qho tseem ceeb mechanism hauv chav cav, lub luag hauj lwm rau kev tswj hwm lub sijhawm thiab kev txav ntawm lub cav nkag thiab tso tawm hauv lub cav hluav taws xob. Nws txoj haujlwm yog qhov tseem ceeb rau kev ua haujlwm zoo, lub hwj chim, thiab ua haujlwm smoothness hauv chav-powered machinery. Los ntawm locomotives mus nyob ruaj ruaj cav, iav iav piv txwv txog kev sib tshuam ntawm cov tshuab ntsuas thiab engineering tshiab.

Cov Hauv paus ntawm Valve Iav

Lub hom phiaj tseem ceeb ntawm valve iav yog los tswj kev ntws ntawm cov chav ntws mus rau hauv thiab tawm ntawm lub cav cov thooj voos kheej kheej. Qhov no cuam tshuam nrog ob qho haujlwm tseem ceeb:

1. Chav Nkag Nkag: Qhib lub li qub kom tso cov hluav taws xob siab kom nkag mus rau lub tog raj kheej, tsav lub piston.
2. Chav tso pa tawm: qhib lub li qub kom tso cov chav siv, npaj lub tog raj kheej rau kev ua voj voog tom ntej.

Los ntawm synchronizing cov txheej txheem no, iav valve kom paub tias lub cav ua haujlwm zoo thiab muab cov hluav taws xob siab tshaj plaws.

Hom Valve Iav

Tau ntau xyoo, ntau tus qauv ntawm Valve iav tau tsim, txhua qhov kev pab cuam tshwj xeeb. Qee cov hom uas tsis tau muaj xws li:

• Stephenson valve iav:Ib qho ntawm qhov ntxov thiab feem ntau siv hom hom, paub rau nws cov kev yooj yim thiab kev ntseeg tau.
• Walschaerts valve iav:Dav siv nyob rau hauv locomotives, muab kev tswj hwm thiab txo tau cov kev hnav ntawm cov khoom siv.
• Baker Valve Iav:Tus qauv tsim qauv tom qab uas tshem tawm cov chaw zawv zawg, muab cov txheej txheem ruaj khov dua thiab ua tau zoo.
• CaprottI Valve iav:Lub poppet valve siv hauv qee cov pa hluav taws xob niaj hnub, hais txog kev ua haujlwm thiab txo kev txij nkawm. Pipeline li qub iav

Nchuav iav Belon IAV Chaw Tsim Tshuaj - Shanghai Belon Machinery Co., Ltd.

Valve Iav Systems Hauv Cov Hluav Taws Xob Chav Txhua Yam Yuav Siv Spur Zog los yog Bevel Zog, nyob ntawm qhov tshwj xeeb tsim thiab lub hom phiaj:

1. Spur zog

Spur iav Nquag hauv cov kev yooj yim dua cov me nyuam ntawm cov hniav cov hniav uas sib piv rau cov iav axis.
Siv rau kev xa cov lus tsa suab ntawm parallel Shafts hauv valve tshuab.
Nyiam rau lawv yooj yim ntawm kev tsim khoom thiab ua kom cov lus tsa suab kis tau.
2. Bevel Zog
Bevel IavSiv thaum cov lus tsa suab tau raug kis tau ntawm shafts ntawm kaum sab xis, feem ntau 90 degrees.
Pom nyob rau hauv qee cov kab valve, tshwj xeeb tshaj yog thaum cov txheej txheem cav yuav tsum muaj cov lus taw kev rau angular cia.

3. Helical zog(Tsawg kawg hauv lub xov tooj valve)

Qee zaum siv rau smoother thiab quieter kev ua haujlwm, tab sis tsis tshua muaj vim yog cov nyom thiab tus nqi.
Feem ntau, cov zog hauv cov iav xov xwm valve ua ntej kev ua haujlwm ntawm kev nrawm nrawm, muab cov kev ua haujlwm ntawm cov pa hluav taws xob.

Cheebtsam thiab ua haujlwm

Ib lub valve iav system muaj ob peb yam: eccentric cov pas, cov ntawv txuas, levers, thiab yog li qub lawv tus kheej. Cov lus tsa suab ntawm cov ntu no yog muab tau los ntawm lub cav Crankshaft lossis cov log tsav tsheb, ua kom meej meej synchronization nrog piston lub zog. Kev kho kom haum nyob rau hauv valve lub sijhawm kuj tseem tuaj yeem tsim kom haum rau kev sib txawv lossis cov kev ua haujlwm uas paub tias "tsis paub txog" lossis "txuas."

Lub luag haujlwm hauv kev ua tau zoo thiab ua tau zoo

Ib lub dab tsi uas qhib thiab kawtej cuab tam cuam ​​tshuam loj heev lub cav cua sov ua haujlwm. Lub sijhawm ua haujlwm tau zoo minimizes ncu ncu hluav taws xob thiab ua kom cov cav ua haujlwm nyob rau hauv nws txoj kev ua siab zoo. Cov kws ua choj feem ntau sim nrog kev sib txawv ntawm lub valve rau kev ua kom muaj zog ntau dua thaum txo cov roj thiab kev noj dej.

Txoj Cai Zoo thiab Niaj Hnub No

Thaum cov tshuab nqus dej tau hloov ntau ntawm cov khoom siv hluav taws xob sab hauv thiab cov tshuab hluav taws xob tseem ceeb rau cov paj hauv keeb kwm kev nyiam thiab kev tshawb fawb txog kev ua engineering. Ntau cov cuab yeej cuab tam Railways thiab cov neeg nyiam ua kom cov ncej tseem ciaj sia los ntawm kev tswj hwm thiab rov ua dua chav locomotives nrog ntau ntau txoj kev tsim hluav taws xob.
