Hydraulic balance valve Excavator hydraulic cylinder valve core COHA-XAN

Cartridge valve ndi mtundu wina wa hydraulic control valve palimodzi. Chigawo choyambirira ndi chowongolera chamadzimadzi, chowongolera chimodzi chanjira ziwiri zamadzimadzi chomwe chimayikidwa pagawo lalikulu la gawo lamafuta (kotero limatchedwanso valavu ya cartridge yanjira ziwiri).
Magawo osiyanasiyana owongolera a valve ya cartridge amatha kupangidwa pophatikiza chinthu chimodzi kapena zingapo zoyikapo ndi magawo owongolera oyendetsa. Monga gawo lowongolera mayendedwe, unit control control unit, flow control unit, compound control unit unit.
Valve ya cartridge ili ndi zizindikiro zotsatirazi: kukana kwamkati kochepa, koyenera kuyenda kwakukulu; Madoko ambiri a valve amasindikizidwa ndi cone, kotero kutayikira kumakhala kochepa, ndipo sing'anga yogwira ntchito monga emulsion imakhalanso yoyenera kwa dongosolo losavuta, ntchito yodalirika komanso yokhazikika; Pakuyenda kwakukulu, kuthamanga kwambiri, zovuta kwambiri za hydraulic system zimatha kuchepetsa kukula ndi kulemera kwake.
Cartridge ndi gulu lazinthu zambiri, lomwe lili ndi zinthu zofunika kwambiri monga spool, manja a valve, kasupe ndi mphete yosindikizira yomwe imayikidwa mu thupi la valve lopangidwa mwapadera komanso lokonzedwa. Ndilofanana ndi A hydraulically controlled check valve yokhala ndi ma doko awiri amafuta omwe amagwira ntchito A ndi B) ndi doko limodzi lamafuta (X). Kusintha kukakamiza kwa doko lamafuta kumatha kuwongolera kutsegula ndi kutseka kwa madoko amafuta A ndi B. Pamene doko lolamulira lilibe mphamvu ya hydraulic, kuthamanga kwamadzi pansi pa valavu kumaposa
Mphamvu yamasika, valavu imakankhidwa motseguka, A ndi B amalumikizidwa, ndipo komwe kumayendera madzi kumatengera kukakamiza kwa madoko A ndi B. M'malo mwake, doko loyang'anira limakhala ndi A hydraulic effect, ndipo px≥pA ndi px≥pB, limatha kutsimikizira kutseka pakati pa doko A ndi doko B.
Ma valve a cartridge amatha kugawidwa m'magulu awiri molingana ndi mafuta olamulira: mtundu woyamba ndi valavu ya cartridge yoyendetsedwa kunja, mafuta olamulira amaperekedwa ndi A gwero lamphamvu lapadera, kupanikizika kwake sikukugwirizana ndi kusintha kwamphamvu kwa madoko A ndi B, ndi amagwiritsidwa ntchito kwambiri poyang'anira kayendetsedwe ka kayendetsedwe ka mafuta; Mtundu wachiwiri ndi valavu ya cartridge yoyendetsedwa mkati.
Valve yamitundu iwiri ya cartridge ili ndi mawonekedwe amphamvu yayikulu, kutsika kwapang'onopang'ono, koyenera kuyendetsa bwino ma hydraulic system, stroke yayikulu yayifupi ya spool, kuchitapo kanthu, mphamvu yolimbana ndi mafuta, kapangidwe kosavuta, kukonza kosavuta, pulagi ili ndi mawonekedwe. valavu imodzi yamagetsi ambiri. Chifukwa chake, amagwiritsidwa ntchito kwambiri pamakina osiyanasiyana a hydraulic
M'dongosolo, monga zofukula, ma cranes, ma cranes amagalimoto, makina oyendetsa sitima ndi zina zotero.
