Valavu yothandizira PC220-6 Vavu yotchinga yotchinga 708-2L-04740

Pali mitundu yambiri ya ma valve a solenoid pazofukula zazing'ono. Choyamba, tiyenera kudziwa mfundo ntchito valavu solenoid. Valavu ya solenoid yamakina okumba imagwiritsa ntchito ma elekitiromagineti kukankhira pachimake cha valve kuwongolera komwe mpweya woponderezedwa, kuti uwongolere kolowera kwa pneumatic actuator switch. Electromagnetic directional valve malinga ndi zofunikira zosiyanasiyana zimatha kukwaniritsa njira ziwiri, ziwiri, zisanu ndi zina zotero
Choyamba, kapangidwe ka valavu solenoid: koyilo, maginito, ejector ndodo.

Mfundo yogwira ntchito ya valve solenoid ya chofukula chaching'ono ndi yakuti pamene koyiloyo ikugwirizana ndi zamakono, imapanga maginito, imakopana wina ndi mzake ndi maginito, maginito amakoka ndodo ya ejector, amazimitsa mphamvu, maginito ndi ejector ndodo. zimakonzedwanso, ndipo ntchitoyo imamalizidwa.

Chachiwiri, maginito amagetsi omwe amagwiritsa ntchito valavu ya solenoid pa chokumba chaching'ono amagawidwa kukhala AC ndi DC.

Mphamvu yamagetsi yamagetsi ya AC nthawi zambiri imakhala 220V, yomwe imadziwika ndi mphamvu yayikulu yoyambira, nthawi yayifupi yosinthira komanso mtengo wotsika. Komabe, pamene chigawo cha valve sichinamamatira mokwanira ndipo chitsulo sichimayamwa, maginito a electromagnet ndi osavuta kuwotcha chifukwa cha kuchulukira kwamakono, kotero kuti mwayi wogwira ntchito ndi wosauka, zomwe zimachitika, ndipo moyo ndi waufupi. Mphamvu yamagetsi yamagetsi yamagetsi ya DC nthawi zambiri imakhala 24V, ndipo ubwino wake ndikuti imagwira ntchito modalirika, sidzawotcha chifukwa cha spore kumamatira, ndipo imakhala ndi moyo wautali.

Chachitatu, gulu la solenoid mavavu

1, valavu ya solenoid yolunjika
Mphamvu ikayaka, mphamvu yamagetsi yopangidwa ndi koyilo yamagetsi imakweza chidutswa chotseka kuchokera pampando, ndipo valavu imatchedwa. Mphamvu ikatha, valavu ya solenoid imatha, kasupe amakankhira mbali yotseka pampando, ndipo valve imatsekedwa. Amadziwika ndi ntchito yanthawi zonse mu vacuum, kupanikizika koyipa ndi kukakamiza kwa ziro, koma m'mimba mwake nthawi zambiri sapitilira 25mm.

2, valavu yoyendetsa solenoid
(Pilot solenoid valve working mfundo)

Ikayatsidwa, mphamvu yamagetsi yamagetsi imatsegula dzenje loyendetsa ndege, kuthamanga kwa chipinda chapamwamba kumatsika mofulumira, kupanga kusiyana kochepa komanso kuthamanga kwakukulu kuzungulira gawo lotseka, kuthamanga kwamadzimadzi kumakankhira mbali yotseka kuti ipite mmwamba, ndipo valve imatsegulidwa. Mphamvu ikatha, mphamvu ya masika imatseka bowo loyendetsa, ndipo kukakamiza kolowera kumapanga kusiyana kocheperako komanso kuthamanga kwambiri kuzungulira gawo lotseka la valve kudzera pabowo lodutsa mwachangu, ndipo kuthamanga kwamadzi kumakankhira gawo lotseka kuti lisunthike ndikutseka. valavu. Imadziwika ndi malire apamwamba amtundu wa kuthamanga kwamadzimadzi ndipo imatha kukhazikitsidwa mosasamala (kuti ikhale yosinthidwa) koma iyenera kukumana ndi kusiyana kwa kuthamanga kwamadzi.
