Hydraulic balance valve Excavator hydraulic cylinder valve core CXDA-XAN

Mapangidwe oyambira ndi mfundo yogwirira ntchito ya valve control valve
Mapangidwe oyambira a valve control valve makamaka amaphatikiza pakati pa valve, thupi la valavu ndi chida chowongolera chomwe chimayendetsa pachimake cha valve kuti chiziyenda pang'onopang'ono mu thupi la valavu.
Mapangidwe a spool ali ndi mtundu wa valavu ya slide, mtundu wa valve ya cone ndi mtundu wa valve; Kuphatikiza pa dzenje la thupi la valavu kapena dzenje la mpando wa valve wofanana ndi valavu, pali malo olowera mafuta, mafuta otulutsira mafuta ndi chitoliro cha mafuta a chitoliro chakunja pa thupi la valve; Chipangizo chomwe chimayendetsa pachimake cha valve kuti chiziyenda pang'onopang'ono mu thupi la valve chikhoza kukhala njira yosinthira pamanja, kapena ikhoza kukhala kasupe kapena electromagnet, ndipo nthawi zina, mphamvu ya hydraulic imagwiritsidwa ntchito poyendetsa.
Potengera mfundo yogwirira ntchito, valavu yoyendetsa yoyendetsa imagwiritsa ntchito kayendedwe ka spool mu thupi la valavu kuti muchepetse kutseguka ndikutsegulidwa kwa doko la valavu kuti ithe kupanikizika, kuyenda ndi kuwongolera. Pamene valavu yoyendetsera ntchito ikugwira ntchito, kukula kwa doko kwa ma valve onse, kusiyana kwapakati pakati pa ma valavu olowera ndi kutuluka, ndi kutuluka kwa valavu kumagwirizana ndi njira yoyendetsera doko, koma magawo omwe amayendetsedwa ndi ma valve osiyanasiyana ndi ofanana. osati chimodzimodzi.
