Ma hydraulic control check valve YDF10-00 for excavator

Chizindikiro cha valve solenoid chimasonyeza kutsogolo "ambiri". Muyenera kuwona momwe valavu iyi ikugwirira ntchito. Mutha kunena kuti alipo angapo. Mudzakhala ndi chidziwitso chabwinoko ngati pali chisindikizo cha pneumatic. Mophiphiritsa, amatanthauza lalikulu la bolodi lozungulira mafuta (lokhala ndi chizindikiro cha mivi kapena mzere wa T). Ndipo "malumikizidwe angapo" kumbuyo amatanthauza kuti pali mfundo zingapo pa lalikulu (mfundo yodutsa mzere wa chizindikiro cha muvi ndi mzere wa T), womwe ndi maulalo angapo. Tanthauzo la zithunzi zophiphiritsa nthawi zambiri ndi motere:

1. Mbali yogwira ntchito ya valve yachiwiri yothandizira imayimiridwa ndi mabwalo, ndipo mabwalo angapo amaimira "malo" angapo;

2. Chizindikiro cha mivi m'bokosilo chimasonyeza kuti njira ya mafuta ili mu chikhalidwe cholumikizidwa, koma malo a chizindikiro cha muvi sikutanthauza kumene kumachokera madzi ndi madzi;

3. Zolembedwa "T" kapena "T" m'bokosi zikuwonetsa kuti tchanelo chatsekedwa;

4. Ngati zitsulo zingapo zikugwirizana ndi kunja kwa bokosi, zikutanthauza "malumikizidwe" angapo;

5. Opanga ma valve a cartridge general amagwiritsa ntchito chilembo P kuti asonyeze mpweya wolowera / mpweya wokhudzana ndi dera la mafuta kapena mpweya woperekedwa ndi pulogalamu ya pulogalamu; Pampu yamafuta / mpweya wobwereranso doko lolumikizidwa pakati pa valavu ndi njira yobwezera mafuta / mpweya wa pulogalamu yamakina imatanthauzidwa ndi T (nthawi zina O); Bowo la mafuta / mpweya wolumikiza valavu ndi actuator imasonyezedwa ndi ab Nthawi zina kuika L pa chithunzi cha chizindikiro kumasonyeza kuti dzenje la mafuta likutuluka;

6. Ma valve oyendetsa ma hydraulic ali ndi malo awiri kapena angapo ogwira ntchito, imodzi mwazomwe zimakhala zokhazikika, ndiko kuti, malo omwe chigawo cha valve sichimayendetsedwa ndi mphamvu. Kulumikizana kolakwika pachithunzi choyimira ndi malo okhazikika a valve yokhala ndi magawo atatu. Valavu yokhala ndi magawo awiri yoyendetsedwa ndi kasupe wa torsion imatenga momwe njanji zilili mubokosi lomwe lili pafupi ndi kasupe wa torsion monga momwe amakhalira. Mukapanga chithunzi chadongosolo, njira yamafuta / mpweya iyenera kulumikizidwa ndi malo okhazikika a hydraulic valve.
