Kodi valavu yamoto ndi chiyani
valavu yamagalimoto yamagalimoto ndi gawo lofunikira la injini yamagalimoto, yomwe ili pakati pa mutu wa silinda ndi mpando wa masika a valve rod mchira. Ntchito yake yayikulu ndikuwonetsetsa kuti valavu imakhala nthawi yake ndipo imayikidwa mwamphamvu kuti valavu isagwedezeke panthawi ya kugwedezeka kwa injini, motero kuwononga kusindikiza kwake.
Akasupe a valve nthawi zambiri amapangidwa ndi waya wapamwamba kwambiri wazitsulo ndipo amatenthedwa kuti awonjezere kutopa kwawo. Pofuna kupewa dzimbiri masika, pamwamba adzakhala kanasonkhezereka kapena phosphating. Mapeto ake awiri ayenera kukhala pansi ndi perpendicular kwa kasupe axis kuti ateteze skew pa ntchito.
Mapangidwe ndi kusankha zinthu za kasupe wa valve zimakhudza kwambiri momwe injini ikuyendera. Pofuna kupewa kumveka, ma injini amakono nthawi zambiri amagwiritsa ntchito akasupe osinthira phula kapena akasupe okwera kawiri. Kapangidwe kawiri kasupe kumaphatikizapo akasupe awiri ozungulira mozungulira mkati ndi kunja. Kuuma kwa kunja kwa masika ndi kwakukulu, komwe kungalepheretse bwino resonance, ndipo pamene kasupe wina wathyoka, winayo akhoza kupitiriza kugwira ntchito kuti atsimikizire kutsekedwa kwabwino kwa valve.
Mfundo yogwira ntchito ya kasupe wa valve ndikuonetsetsa kuti valavu ikugwirizana kwambiri ndi mpando wa valve pogonjetsa mphamvu ya inertia panthawi ya kutseka kwa valve ndikuletsa valavu kudumpha pansi pa katundu wopanikizika. Kuphatikiza apo, kasupe wa valavu amathanso kuwongolera kayendetsedwe ka valve kuti apewe kulekanitsidwa kwa makina a valve .
Mwachidule, ngakhale kasupe wa valavu ndi kakang'ono mu injini, udindo wake ndi wofunikira kuti zitsimikizire kuti injiniyo ikugwira ntchito bwino komanso yokhazikika.
Udindo waukulu wa ma valve oyendetsa galimoto umaphatikizapo izi:
Onetsetsani kuti mpando wa valve panthawi yake ndi wokwanira bwino : kasupe wa valve akhoza kuonetsetsa kuti valavu ikhoza kutsekedwa mwamphamvu ndi mpando wa valve kapena mpando wa valve pamene yatsekedwa, kuteteza valavu kuti idumphe pamene injini ikugwedezeka, kuti ikhale yosindikizidwa bwino.
Kugonjetsa mphamvu ya inertial : pamene valve imatsegulidwa, makina a valve adzatulutsa mphamvu zopanda mphamvu, kasupe wa valve akhoza kugonjetsa mphamvu zopanda mphamvuzi kuti zitsimikizire kuti ziwalo zopatsirana zimayendetsedwa nthawi zonse ndi CAM ndipo sizimalekanitsidwa.
kuteteza resonance ndi flutter : pofuna kupewa valavu kasupe resonance ntchito, injini zina amagwiritsa ntchito ma valve awiri kasupe kasupe, awiri kasupe kasinthasintha moyang'anizana ndi, amene angathe kuthetsa kugwedezeka kwa kasupe wina ndi mzake, kusintha kukhazikika kwa valavu kasupe.
Kulimbitsa kutopa komanso kudalirika : Akasupe a valve nthawi zambiri amapangidwa ndi waya wachitsulo wapamwamba kwambiri komanso amatenthedwa kuti asatope. Pofuna kupewa dzimbiri, pamwamba pake ndi galvanized kapena phosphating.
Zogwirizana ndi kupsinjika kwamphamvu komanso kuthamanga kwambiri : ndi injini kupita ku mphamvu zambiri, chitukuko chothamanga kwambiri, akasupe a valve amafunika kupirira kupsinjika kwakukulu komanso kuthamanga kwachangu. Chifukwa chake, kupanga ndi kupanga akasupe a valve kumafunikira luso lapamwamba kwambiri.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
