Valavu ya hydraulic balance valve Vavu yayikulu yolumikizana ndi CXED-XCN cartridge valve

Mapangidwe oyambira a valve control valve
Valavu yowongolera imapangidwa makamaka ndi thupi la valve, spool, masika, chizindikiro ndi mbali zina. Pakati pawo, thupi la valve ndilo thupi lalikulu la valve yonse, ndipo dzenje lamkati limaperekedwa kuti liwongolere madziwo. Spool imayikidwa mu thupi la valve ndipo imatha kusuntha kuti isinthe kukula kwa dzenje, potero kulamulira kutuluka kwa madzi. Springs nthawi zambiri amagwiritsidwa ntchito kuti apereke kusintha ndi malipiro a malo a spool kuti apitirize kuyenda mokhazikika. Chizindikirocho chimagwiritsidwa ntchito kusonyeza kuchuluka kwa magalimoto.
Mfundo ya proportional solenoid valve

Zimatengera mfundo ya solenoid switch valve: mphamvu ikatha, kasupe amakankhira pachimake chachitsulo molunjika pampando, kutseka valavu. Koyiloyo ikapatsidwa mphamvu, mphamvu yamagetsi yamagetsi yomwe imatuluka imagonjetsa mphamvu ya masika ndikukweza pachimake, motero imatsegula valavu. Valavu yofananira ya solenoid imapanga zosintha zina pamapangidwe a solenoid on-off valve: mphamvu yamasika ndi mphamvu yamagetsi yamagetsi zimayenderana pansi pa koyilo iliyonse. Kukula kwa koyilo yamakono kapena kukula kwa mphamvu yamagetsi yamagetsi kumakhudza kugunda kwa plunger ndi kutseguka kwa valavu, ndipo kutsegula kwa valve (kuthamanga kwa magazi) ndi koyilo yamakono (chizindikiro chowongolera) zimakhala ndi mgwirizano wabwino kwambiri. . Direct acting proportional solenoid mavavu amayenda pansi pa mpando. Sing'anga imayenda pansi pa mpando wa valve, ndipo mphamvu yake ndi yofanana ndi mphamvu yamagetsi, koma mosiyana ndi mphamvu ya masika. Choncho, m'pofunika kukhazikitsa chiwerengero cha ziwerengero zazing'ono zomwe zimagwirizana ndi mtundu wa ntchito (coil current) mu kayendetsedwe ka ntchito. Mphamvu ikazimitsidwa, valavu ya Drake liquid proportional solenoid imatsekedwa (nthawi zambiri imatsekedwa).

Proportional solenoid valve ntchito

Kuwongolera kwamtundu wa kuthamanga kumatheka ndi mphamvu zamagetsi (zowonadi, kuwongolera kuthamanga kungathenso kupindula ndi kusintha kwapangidwe, etc.). Popeza ndi throttle control, payenera kukhala kutaya mphamvu.
