Proportional solenoid valve

Valavu ya proportional solenoid nthawi zambiri imayang'anira kutsegulidwa kwa valavu kudzera pa siginecha yamagetsi yakunja, ndipo imagwiritsidwa ntchito nthawi zambiri kuwongolera kutuluka kwamadzi kudzera mu valavu.

Ma valve oyendera magetsi nthawi zambiri amagwiritsidwa ntchito kuwongolera ndikuwongolera kuthamanga kwamadzimadzi, komwe kuli kusiyana kofunikira pakati pawo, imodzi ndikuwongolera kuthamanga, ina ndikuwongolera ndikuwongolera kuthamanga.

Kapangidwe ka valavu yamagetsi yamagetsi nthawi zambiri imakhala ndi ma valve awiri a proportional solenoid, masensa othamanga ndi owongolera, valavu yofananira imayendetsa kulowera, valavu ina yofananira imayendetsa kutuluka, sensa imayesa kupanikizika, ndipo wowongolera amawongolera kutseguka kwa ma valve awiri ofananira kupyolera mu zizindikiro zowonetsera, kotero kuti kupanikizika m'chipinda chapakati (komanso chofanana ndi kuthamanga kwa kutuluka) kuli kofanana ndi mtengo wokhazikitsidwa.

1. Mfundo yogwiritsira ntchito valavu ya solenoid molunjika: Ikapatsidwa mphamvu, mphamvu yamagetsi yotchedwa electromagnetic coil imakweza mbali yotseka pampando, ndipo valavu imatsegula;Mphamvu ikatha, mphamvu yamagetsi imasowa, kasupe amakankhira mbali yotseka pampando, ndipo valavu imatsekedwa.

2, sitepe ndi sitepe yolunjika yochita valavu ya solenoid: ndikuphatikizira kwachindunji ndi mfundo yoyendetsa, pamene palibe kusiyana pakati pa cholowera ndi chotulukira, pambuyo pa mphamvu, mphamvu yamagetsi yamagetsi mwachindunji kwa woyendetsa yaing'ono valavu ndi zigawo zikuluzikulu zotsekera valavu zimakweza motsatira, valavu imatsegulidwa.Pamene cholowera ndi chotuluka chikafika pakusiyana koyambira, pambuyo pa mphamvu, valavu yamagetsi yamagetsi yamagetsi yamagetsi yaying'ono, valavu yayikulu yotsika m'chipinda chapansi imakwera, kuthamanga kwachipinda chapamwamba kumatsika, kuti mugwiritse ntchito kusiyana kwamphamvu kukankhira valavu yayikulu m'mwamba;Mphamvu ikazimitsidwa, valavu yoyendetsa ndege imagwiritsa ntchito mphamvu ya masika kapena kukakamiza kwapakatikati kukankhira gawo lotseka ndikusunthira pansi kutseka valavu.

3, mfundo ya valve solenoid yoyendetsa ndege: ikayatsidwa, mphamvu yamagetsi yamagetsi imatsegula dzenje loyendetsa, kupanikizika kwa chipinda chapamwamba kumatsika mofulumira, kupanga kusiyana kotsika komanso kuthamanga kwakukulu kuzungulira gawo lotseka, kuthamanga kwamadzi kumakankhira mbali yotseka kuti ipite mmwamba, valavu imatsegula;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.
