Iyini igiya le-Valve?

Ukuqonda Imishini Yevalvu: Isimangaliso Sobunjiniyela

Igiya levalvukuyindlela ebalulekile ezinjinini zomusi, enesibopho sokulawula isikhathi kanye nokuhamba kokungena komusi kanye nokukhipha umoya ezitsheni zenjini. Umsebenzi wayo ubalulekile ekwenzeni ngcono ukusebenza kahle, amandla, kanye nokushelela kokusebenza kwemishini esebenzisa umusi. Kusukela ezinjinini ezisebenza ngomusi kuya ezinjinini ezimile, igiya le-valve limelela ukuhlangana okuthakazelisayo kokunemba kwemishini kanye nokusungula izinto ezintsha zobunjiniyela.

Izisekelo Zegiya Levalvu

Inhloso eyinhloko yegiya le-valve ukulawula ukugeleza komusi okungena nokuphuma kumasilinda enjini. Lokhu kuhilela imisebenzi emibili ebalulekile:

1. Ukungena Ngomusi: Ukuvula amavalvu ukuze umusi ocindezelwe kakhulu ungene esilinda, oqhuba i-piston.
2. Ukukhipha Umoya Ngomusi: Ukuvula amavalvu ukuze kukhishwe umusi osetshenzisiwe, kulungiselela isilinda umjikelezo olandelayo.

Ngokuvumelanisa lezi zinqubo, igiya le-valve liqinisekisa ukuthi injini isebenza kahle futhi inikeza amandla aphezulu.

Izinhlobo Zegiya Levalvu

Eminyakeni edlule, kuye kwaklanywa imiklamo eminingana yegiya lama-valve, ngayinye inikeza izinzuzo ezihlukile. Ezinye zezinhlobo eziphawuleka kakhulu zifaka:

• I-Stephenson Valve Gear:Enye yezinhlobo zokuqala nezisetshenziswa kakhulu, eyaziwa ngokulula kwayo nokuthembeka kwayo.
• Imishini ye-Walschaerts Valve:Isetshenziswa kakhulu ezinqolobaneni, inikeza ukulawula okunembile kanye nokuncipha kokuguguleka kwezingxenye.
• Imishini ye-Baker Valve:Umklamo wakamuva osusa izingxenye ezishelelayo, ohlinzeka ngohlelo oluhlala isikhathi eside nolusebenza kahle.
• I-Caprotti Valve Gear:Uhlelo lwamavalvu olusetshenziswa kwezinye izinjini zesimanje zomusi, olugcizelela ukusebenza kahle kanye nokugcinwa okuncishisiwe. Amavalvu epayipi igiya

Izinhlelo zamagiya e-valve ezinjinini zomusi zivame ukusebenzisa amagiya e-spur noma amagiya e-bevel, kuye ngomklamo kanye nenhloso ethile:

1. Amagiya e-Spur

Igiya le-Spur Kuvamile ezindleleni ezilula zegiya lama-valve lapho amazinyo egiya ehambisana ne-axis yegiya.
Isetshenziselwa ukudlulisa ukunyakaza phakathi kwemishayo ehambisanayo ezindleleni zamavalvu.
Kukhethwa ngenxa yokuthi kulula ukukhiqiza kanye nokudlulisa ukunyakaza okunembile.
2. Amagiya e-Bevel
Igiya le-Bevelisetshenziswa lapho ukunyakaza kudinga ukudluliselwa phakathi kwama-shaft nge-engeli, ngokuvamile ama-degree angu-90.
Kutholakala emiklamo ethile yegiya lama-valve, ikakhulukazi lapho ukwakheka kwenjini kudinga ukuqondiswa kabusha kokunyakaza kwe-angular.

3. Amagiya Ajikelezayo(Akuvamile ezinhlelweni zamagiya e-valve)

Ngezinye izikhathi isetshenziswa ukuze isebenze kahle futhi ithule, kodwa ayivamile ngenxa yobunzima kanye nezindleko.
Ezimweni eziningi, amagiya ezinhlelweni zamagiya e-valve abeka phambili ukuqina nokuthembeka kunesivinini, uma kubhekwa izidingo zokusebenza kwezinjini zomusi.

Izingxenye kanye Nokusebenza

Uhlelo olujwayelekile lwegiya le-valve luhlanganisa izingxenye eziningana: izinduku ezingavamile, izixhumanisi, ama-lever, kanye nama-valve ngokwawo. Ukunyakaza kwalezi zingxenye kususelwa ku-crankshaft yenjini noma amasondo okushayela, okuqinisekisa ukuvumelanisa okunembile nokunyakaza kwe-piston. Ukulungiswa kwesikhathi se-valve kungenziwa futhi ukuze kuhlangatshezwane nemithwalo noma izimo zokusebenza ezahlukahlukene, inqubo eyaziwa ngokuthi “ukuxhumanisa” noma “ukuxhumanisa.”

Indima Ekusebenzeni Kahle Nokusebenza Kahle

Ivalvuigiya kuthinta kakhulu ukusebenza kahle kokushisa kwenjini. Isikhathi esifanele sinciphisa ukumosheka komusi futhi siqinisekisa ukuthi injini isebenza ngaphakathi kwemingcele yayo efanele. Onjiniyela bavame ukuzama izilungiselelo ezahlukene zamavalvu ukuze bandise ukukhishwa kwamandla ngenkathi benciphisa ukusetshenziswa kukaphethiloli namanzi.

Ifa Nokufaneleka Kwanamuhla

Nakuba izinjini zomusi sezithathelwe indawo kakhulu yizinjini zomlilo zangaphakathi kanye nezinjini zikagesi, igiya lama-valve lisalokhu liyinto ethakazelisayo ezifundweni zokulondolozwa komlando kanye nobunjiniyela. Izitimela eziningi zasendulo kanye nabathandi bagcina leli gama liphila ngokugcina nokubuyisela izitimela zomusi ngemiklamo ehlukahlukene yamagiya ama-valve.
