Vavu yofukula ya solenoid 423-4562 yofanana ndi valavu ya solenoid

Electromagnetic proportional valve ntchito mfundo ndi kuzindikira:

Kuwongolera kwa ma valve kumatha kugawidwa m'mitundu iwiri:
Imodzi ndi kusintha kosintha: mwina kutseguka kwathunthu kapena kutsekedwa kwathunthu, kuchuluka kwa kuthamanga kumakhala kwakukulu kapena kochepa, palibe gawo lapakati, monga ma elekitiroma wamba kudzera mu mavavu, ma valve osinthira ma elekitiroma, ma electro-hydraulic reversing valves.
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.
Chifukwa chake cholinga chogwiritsa ntchito valavu yofananira kapena valavu ya servo ndi: kukwaniritsa kuwongolera koyenda ndi kuwongolera zamagetsi (zowona, pambuyo pakusintha kwadongosolo kungathenso kuwongolera kuthamanga, etc.), popeza ndikuwongolera, payenera kukhala kutaya mphamvu, servo. valavu ndi ma valve ena ndi osiyana, kutaya mphamvu zake kumakhala kwakukulu, chifukwa kumafunika kuyenda kwina kuti kusungitse ntchito ya pre-siteji control mafuta dera.

Mfundo yogwira ntchito ya proportional solenoid valve

Zimatengera mfundo ya solenoid on-off valve: mphamvu ikatha, kasupe amakankhira pachimake pampando, kuchititsa kuti valavu itseke. kolala
Magetsi akagwiritsidwa ntchito, mphamvu yamagetsi yopangidwa ndi electromagnetic imapambana mphamvu yamasika ndikukweza pachimake, motero amatsegula valavu. Valavu yofananira ya solenoid imapanga zosintha zina pamapangidwe a valavu ya solenoid: imapanga malire pakati pa mphamvu yamasika ndi mphamvu yamagetsi yamagetsi pansi pa koyilo iliyonse. Kukula kwa koyilo yapano kapena kukula kwa mphamvu yamagetsi kumakhudza kugunda kwa plunger ndi kutseguka kwa ma valve, ndipo kutsegula kwa valve (kuyenda) ndi koyilo (chizindikiro chowongolera) ndiubwenzi wabwino kwambiri.
Direct acting proportional solenoid valve imayenda pansi pa mpando. Sing'anga imayenda kuchokera pansi pa mpando, ndipo mayendedwe a mphamvu ndi ofanana ndi mphamvu yamagetsi, ndipo mosiyana ndi mphamvu ya masika. Choncho, m'pofunika kukhazikitsa maulendo apamwamba komanso ocheperako omwe akugwirizana ndi mtundu wa ntchito (coil current) mu kayendetsedwe ka ntchito. Valavu yofananira ya solenoid ya Drey fluid imatsekedwa (NC, yomwe nthawi zambiri imatsekedwa) mphamvu ikazimitsidwa.
