Solenoid valve msonkhano 211-2092 Solenoid valve hydraulic valve

Kodi pali kusiyana kotani pakati pa valavu yofananira ndi valavu wamba ya solenoid?

Proportional valve ndi mtundu watsopano wa chipangizo chowongolera ma hydraulic. Mu valavu yamagetsi wamba, valavu yothamanga ndi valavu yolowera, ma electromagnet wofananira amagwiritsidwa ntchito m'malo mwa gawo lowongolera, malinga ndi magetsi olowera.
Chizindikiro cha gasi chimayang'anira mosalekeza komanso molingana ndi kuthamanga, kuyenda, kapena komwe kumayendera mafuta patali. Ma valve ofananira nthawi zambiri amakhala ndi chiwongola dzanja, ndipo kuthamanga kwake komanso kuthamanga kwake sikungakhudzidwe ndi kusintha kwa katundu.

1, valavu wamba sali wolingana ndi kuwongolera kopitilira muyeso, ndi valavu imodzi yokha yosinthira, njira yotsegulira valavu, kuchuluka kotsegulira kapena mphamvu yoyika masika ndizotsimikizika.
Sizingasinthidwe malinga ndi zochitika zenizeni.

2, valavu yofananira imayenderana ndi kuwongolera masitepe mosalekeza, malinga ndi momwe zinthu zilili zenizeni zomwe zimasonkhanitsidwa ku chandamale chowongolera chipukuta misozi, njira yotsegulira valavu, kuchuluka kotsegulira kapenamphamvu ya masika imatsatiridwa, kuti akwaniritse kusintha kosalekeza kosalekeza mu kayendetsedwe ka kayendetsedwe kake. Kuwongolera kwa valavu kumatha kugawidwa m'mitundu iwiri: imodzi ndikusintha kosinthika: mwina kutseguka kwathunthu, kapena kutsekedwa kwathunthu, kuyenda ndi mwina, kapena kakang'ono, kopanda dera lapakatikati, monga ma elekitiroma wamba kudzera mu valavu, valavu yosinthira ma elekitirodi, ma electro-hydraulic reversing. valavu. Zina ndikuwongolera mosalekeza: doko la valve likhoza kutsegulidwa malinga ndi kufunikira kwa digiri iliyonse yotsegulira, potero kulamulira kukula kwa kutuluka, ma valve oterowo ali ndi ulamuliro pamanja, monga ma throttle valves, komanso amawongoleredwa pakompyuta, monga molingana. ma valve, ma servo valves.

Proportional solenoid valve

Momwe zimagwirira ntchito:

Zigawo zonse za valavu ya solenoid ndi koyilo yamagetsi malinga ndi gawo lamagetsi, ndiye kuti, chowongolera. Inductor ikapatsidwa chizindikiro chamagetsi, gawo lamagetsi lomwe limapangidwa ndi pano limapangitsa kuti valavu yapakati isunthike ndikuzindikira kusintha kwa magawo olamulidwa.
Chizindikiritso chaubwino:
Koyilo iliyonse yamagetsi imakhala ndi mtengo wokhazikika wokana R, koma R uyu sangakhale "0" kapena "∞", pomwe R= "0" ikuwonetsa dera lalifupi lamkati: pomwe R= "∞" ikuwonetsa dera lotseguka lamkati; ndi
Kukana kwa koyilo ku nyumba sikungakhale "0". Ngati zomwe zili pamwambazi zitha kukumana ndipo valavu ya solenoid sikugwira ntchito, zikhoza kukhala kuti kulowetsa kwa chizindikiro ndikolakwika kapena chigawo cha valve chatsekedwa.
