Zida zofukula 702-75-04600 valavu yopumira ya hydraulic valve

Mfundo yogwira ntchito ya proportional solenoid valve
Zimatengera mfundo ya solenoid on-off valve: mphamvu ikatha, kasupe amakankhira pachimake pampando, kuchititsa kuti valavu itseke. Koyiloyo ikapatsidwa mphamvu, mphamvu yamagetsi yopangidwa ndi electromagnetic imapambana mphamvu yamasika ndikukweza pachimake, motero kutsegulira 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 yamakono kapena kukula kwa mphamvu yamagetsi kumakhudza kugunda kwa plunger ndi kutseguka kwa valve, ndi kutsegula kwa valve (kuthamanga) ndi koyilo yamakono (chilembo chowongolera)
Ndi mgwirizano wabwino wa mzere.
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.
