Kodi valavu ya solenoid imagwira ntchito bwanji?

Choyamba, ma valve omwe ali pamwambawa amagwiritsidwa ntchito m'madera onse a pneumatic ndi hydraulic. Kachiwiri, makina a pneumatic ndi hydraulic nthawi zambiri amagawidwa kukhala gwero lamadzimadzi a gasi ndi makina opangira, zida zowongolera, ndi zida zazikulu. Mavavu osiyanasiyana omwe nthawi zambiri amatchulidwa pamwambapa amagwiritsa ntchito zida zamagetsi. Kunena mosapita m'mbali, ndikuwongolera media kapena magawo osiyanasiyana amagetsi amagetsi amagetsi. Si kanthu kena koma njira, kuyenda, ndi kupanikizika. Ma valve omwe ali pamwambawa amachitadi ntchitoyi.
Tiyeni tikambirane kaye za valavu yowongolera njira. Kunena mosapita m’mbali, ndiko kulamulira mmene madziwo akulowera. Vavu yobwerera kumbuyo ndi valavu ya njira imodzi yomwe nthawi zambiri mumati ndi ya valavu yowongolera. Valavu yobwereranso imakhala ngati mtundu wa zida zamagetsi zomwe zili ndi mitundu yambiri, kutulutsa kwakukulu kokwanira komanso kofunikira. Njira ziwiri zanjira ziwiri, ziwiri zanjira zitatu, ndi zitatu zanjira zisanu zomwe timamva nthawi zambiri ndi ma valve owongolera. Valve yowonjezereka ndi valve yoyendetsera kuthamanga, ndiko kuti, kupanikizika kukafika kapena kupitirira mtengo wokonzedweratu, nthunzi imatulutsidwa kuchokera ku doko losefukira kuti iteteze kupanikizika kwa dongosolo.
Ma valve olingana ndi ma servo amagawa ma valve pamlingo wina. Mwachitsanzo, chiŵerengero chothamanga ndicho kusintha kosasunthika kosasunthika kwa kayendedwe ka deta kwa valve, ndipo chizindikiro chamakono chimagwirizana ndi mphamvu ya mpweya wotuluka. Izi ndizosiyana kwambiri ndi ma valve ochiritsira. Ma valve a servo amagwiritsidwa ntchito mumayendedwe owongolera a servo kuti apititse patsogolo nthawi yoyankha pamakina. Ma valve awa amaphatikizanso kuwongolera kuthamanga komanso kuwongolera kuyenda. Ma valve ofananira ndi ma servo valves ndi okwera mtengo kwambiri kuposa ma valve achikhalidwe amagetsi owongolera komanso kuwongolera kupanikizika, ndipo sagwiritsidwa ntchito kawirikawiri m'makampani opanga makina.
Kodi ntchito yavalve solenoid? Valavu ya solenoid ndi valavu yotseka yomwe imagwiritsa ntchito mphamvu yamagetsi kuwongolera kusintha. Pazida za firiji, ma valve solenoid nthawi zambiri amagwiritsidwa ntchito ngati ma valve otsekera akutali, zida zowongolera zamakina osintha magawo awiri, kapena makina oteteza chitetezo. Valve ya solenoid ingagwiritsidwe ntchito ngati valavu yotsekera kutali, chiwongolero choyang'anira magawo awiri, kapena makina oteteza chitetezo. Angagwiritsidwe ntchito zosiyanasiyana nthunzi, madzi refrigerants, mafuta ndi zinthu zina.
Kwa mayunitsi ang'onoang'ono ndi apakatikati, valavu ya solenoid imalumikizidwa motsatizana papaipi yamadzimadzi isanachitike chipangizo chogwedeza, ndipo chosinthira choyambira chomwechi chimalumikizidwa ngati kompresa. Compressor ikayamba, valavu ya solenoid imatsegulidwa, kulumikiza payipi yamagetsi, kuti gawo lowongolera mpweya lizitha kugwira ntchito moyenera. Compressor ikazimitsidwa, valavu ya solenoid imangodula payipi yamadzimadzi, kulepheretsa madzi a mufiriji kuti asalowenso mu evaporator, ndikupewa kukhudza kwamadzi mufiriji pomwe kompresa iyambanso.
M'nyumba zapakati pa air-conditioning (multi-connected air-conditioning), ma valve solenoid amagwiritsidwa ntchito kwambiri mu mapulogalamu a pulogalamu, kuphatikizapo: ma valve solenoid omwe amawongolera ma valve a njira zinayi, mapaipi amafuta othamangitsidwa ndi compressor, mabwalo otenthetsera, ndi zina zotero.
Udindo wa vacuum solenoid valve:
M'mapaipi, ntchito ya vacuum vacuum valavu imatha kugwiritsa ntchito mfundo yamagetsi kuti izindikire njira yochotsera payipi. Panthawi imodzimodziyo, kutsirizidwa kwa mphamvu yamagetsi yamagetsi kumatha kukhudza kwambiri madera onse ogwiritsira ntchito mapaipi, ndipo kugwiritsa ntchito ma vacuum vacuum kungathenso kulepheretsa zinthu zina zosafunika kwambiri kuti zisokoneze payipi, potero kusintha molondola kayendedwe ka kayendedwe ka mapaipi.
