Vavu ya cartridge ya ulusi SV08-30 valavu yowongolera Direction DHF08S-230

Cartridge valve, yomwe imadziwikanso kuti logic valve, ndi mtundu watsopano wa hydraulic component, yomwe imadziwika ndi mphamvu yothamanga kwambiri, ntchito yabwino yosindikiza, zochitika zomveka komanso zosavuta, choncho zimagwiritsidwa ntchito makamaka muzitsulo zamagetsi zomwe zimakhala ndi kutuluka kwakukulu kapena machitidwe omwe ali ndipamwamba kwambiri. kusindikiza zofunika kuchita.

Mfundo yamapangidwe ndi chizindikiro cha valve ya cartridge
Imakhala ndi mbale yotchinga yowongolera, gawo la cartridge (lopangidwa ndi manja a valve, kasupe, pachimake cha valve ndi chisindikizo),
Chophimba cha cartridge ndi chinthu choyendetsa (chokonzedwa pa mbale yophimba) chimapangidwa. Chifukwa gawo la cartridge la valavu iyi makamaka limagwira ntchito yowongolera ndikuzimitsa mu loop, imatchedwanso njira ziwiri za cartridge. Chophimba chotchinga chowongolera chimakwirira gawo la cartridge mu block ya cartridge ndikulumikizana ndi valavu yoyendetsa ndi cartridge unit (yomwe imadziwikanso kuti valavu yayikulu). Kupyolera mu kutsegula ndi kutseka kwa spool yaikulu ya valve, dera lalikulu la mafuta likhoza kuwongoleredwa. Kugwiritsiridwa ntchito kwa ma valve oyendetsa ndege osiyanasiyana kumatha kukhala kuwongolera kuthamanga, kuwongolera mayendedwe kapena kuwongolera kuyenda, ndipo kumatha kupangidwa ndi kuwongolera kophatikiza. Dongosolo la hydraulic limapangidwa pophatikiza ma valve a cartridge angapo anjira ziwiri okhala ndi magwiridwe antchito osiyanasiyana mu midadada imodzi kapena zingapo za cartridge.

Ponena za mfundo yogwirira ntchito, valavu ya cartridge ya njira ziwiri ndi yofanana ndi valve yoyang'anira madzi. A ndi B ndi madoko awiri okha opangira mafuta ozungulira mafuta (otchedwa ma valve a njira ziwiri), ndipo X ndiye doko lamafuta. Kusintha kuthamanga kwa doko lamafuta kumatha kuwongolera kuyenda kwa madoko amafuta A ndi B
Asa. Ngati palibe hydraulic action pa doko lowongolera, kuthamanga kwamadzi kumunsi kwa spool kumapitilira mphamvu yamasika, ndipo spool imakankhidwa motseguka, magawo A ndi B.
Mayendedwe amadzimadzi amatengera kuthamanga kwa doko A ndi doko B. Mosiyana ndi izi, doko lowongolera limakhala ndi hydraulic action.
Pamene px≥pA kapena px≥pB, kulumikizana pakati pa doko A ndi doko B kumatha kutsekedwa. Mwanjira iyi, chipata "osati" cha chinthu chomveka chimayendetsedwa
Imatchedwanso valavu yomveka.
Ma valve a cartridge amatha kugawidwa m'magulu awiri molingana ndi gwero la mafuta owongolera: mtundu woyamba ndi valavu ya cartridge yoyendetsedwa kunja, ndipo mafuta owongolera amaperekedwa ndi gwero lamphamvu lapadera.
Kupanikizika kulibe chochita ndi kusintha kwamphamvu kwa madoko A ndi B, ndipo amagwiritsidwa ntchito kwambiri pakuwongolera kayendedwe ka mafuta; Mtundu wachiwiri ndi kulowetsedwa koyendetsedwa mkati
Vavu, yomwe imayendetsa doko la A kapena B la valavu yoyera yolowera mafuta, imagawidwa m'mitundu iwiri ya spool yokhala ndi dzenje lonyowa komanso lopanda dzenje, ndipo imagwiritsidwa ntchito kwambiri.
Zambiri.
