Kodi giya ya Valve ndi chiyani?

Kumvetsetsa Zida za Valve: Chodabwitsa cha Uinjiniya

Zida za valavuNdi njira yofunika kwambiri mu injini za nthunzi, yomwe imayang'anira nthawi ndi kayendetsedwe ka nthunzi yolowera ndi kutulutsa mpweya m'masilinda a injini. Ntchito yake ndi yofunika kwambiri pakukonza bwino, mphamvu, ndi kusalala kwa makina oyendetsedwa ndi nthunzi. Kuchokera ku injini zoyendera mpaka ku injini zosasuntha, zida za valve zimayimira malo osangalatsa olumikizirana bwino kwa luso la makina ndi luso la uinjiniya.

Zoyambira za Zida za Valve

Cholinga chachikulu cha zida za valve ndikulamulira kuyenda kwa nthunzi kulowa ndi kutuluka m'masilinda a injini. Izi zimaphatikizapo ntchito ziwiri zofunika:

1. Kulowetsa Nthunzi: Kutsegula ma valve kuti nthunzi yamphamvu ilowe mu silinda, ndikuyendetsa pisitoni.
2. Mpweya Wotulutsa Mpweya: Kutsegula ma valve kuti mutulutse nthunzi yomwe yatha, kukonzekera silinda kuti igwire ntchito yotsatira.

Mwa kugwirizanitsa njira zimenezi, zida za valve zimatsimikizira kuti injini ikugwira ntchito bwino komanso imapereka mphamvu zambiri.

Mitundu ya Zida za Valve

Kwa zaka zambiri, mapangidwe angapo a zida za valve apangidwa, ndipo chilichonse chili ndi ubwino wake wapadera. Mitundu ina yodziwika bwino ndi iyi:

• Zida za Stephenson Valve:Imodzi mwa mitundu yoyambirira komanso yogwiritsidwa ntchito kwambiri, yodziwika chifukwa cha kuphweka kwake komanso kudalirika kwake.
• Zida za Valve ya Walschaerts:Amagwiritsidwa ntchito kwambiri m'magalimoto a injini, kupereka mphamvu yowongolera bwino komanso kuchepetsa kuwonongeka kwa zida.
• Zida za Baker Valve:Kapangidwe katsopano komwe kamachotsa ziwalo zotsetsereka, zomwe zimapangitsa kuti zikhale zolimba komanso zogwira mtima.
• Zida za Caprotti Valve:Makina a ma valavu opangidwa ndi ma poppet omwe amagwiritsidwa ntchito mu injini zina zamakono za nthunzi, zomwe zimagogomezera kugwira ntchito bwino komanso kuchepetsa kukonza.

Wopanga Gear Belon Gear - Shanghai Belon Machinery Co., Ltd.

Makina a ma valve mu injini za nthunzi nthawi zambiri amagwiritsa ntchito ma spur gear kapena bevel gear, kutengera kapangidwe ndi cholinga chake:

1. Magiya Othandizira

Zida zothamanga Zofala kwambiri m'njira zosavuta zogwiritsira ntchito ma valve pomwe mano a ma gear ali ofanana ndi giya.
Amagwiritsidwa ntchito potumiza kayendedwe pakati pa ma shaft ofanana mu njira zama valve.
Amakondedwa chifukwa cha kusavuta kupanga komanso kutumiza mayendedwe molondola.
2. Magiya Ozungulira
Zida za Bevelimagwiritsidwa ntchito pamene kayendedwe kakufunika kutumizidwa pakati pa ma shaft pa ngodya, nthawi zambiri madigiri 90.
Amapezeka m'mapangidwe ena a ma valve, makamaka pamene kapangidwe ka injini kakufuna kusuntha kwa angular.

3. Magiya Ozungulira(Zosowa kwambiri m'makina a ma valve)

Nthawi zina amagwiritsidwa ntchito kuti agwire ntchito bwino komanso mopanda phokoso, koma nthawi zina sagwiritsidwa ntchito kawirikawiri chifukwa cha zovuta komanso mtengo wake.
Nthawi zambiri, magiya omwe ali mumakina a ma valve amaika patsogolo kulimba ndi kudalirika kuposa liwiro, poganizira zofunikira pakugwira ntchito kwa injini za nthunzi.

Zigawo ndi Ntchito

Makina ogwiritsira ntchito ma valve nthawi zambiri amakhala ndi zinthu zingapo: ndodo zosazolowereka, maulalo, ma lever, ndi ma valve okha. Kuyenda kwa magawowa kumachokera ku crankshaft ya injini kapena mawilo oyendetsera, zomwe zimapangitsa kuti piston igwirizane bwino ndi kayendedwe kake. Kusintha nthawi ya ma valve kungapangidwenso kuti kugwirizane ndi katundu wosiyanasiyana kapena mikhalidwe yogwirira ntchito, njira yotchedwa "notching up" kapena "linking."

Udindo mu Kuchita Bwino ndi Kugwira Ntchito

Valavuzida Zimakhudza kwambiri mphamvu ya injini yotenthetsera. Kusunga nthawi koyenera kumachepetsa kuwononga nthunzi ndipo kumaonetsetsa kuti injini ikugwira ntchito bwino. Mainjiniya nthawi zambiri amayesa makonda osiyanasiyana a ma valavu kuti awonjezere mphamvu yotulutsa mphamvu pomwe amachepetsa kugwiritsa ntchito mafuta ndi madzi.

Cholowa ndi Kufunika Kwamakono

Ngakhale kuti mainjini a nthunzi asinthidwa kwambiri ndi mainjini oyaka mkati ndi ma mota amagetsi, zida za ma valve zikadali nkhani yofunika kwambiri pa maphunziro osungira zakale ndi uinjiniya. Sitima zambiri zakale ndi okonda zimasunga mbiri yakale mwa kukonza ndi kubwezeretsa sitima za nthunzi pogwiritsa ntchito mapangidwe osiyanasiyana a zida za ma valve.
