LF10-00 Threaded cartridge throttle hydraulic valve power unit

Valavu ya solenoid ndi sitepe yoyendetsa ndege yoyendetsa galimoto, yomwe imatha kugawidwa kukhala yotsekedwa bwino ya solenoid ndipo nthawi zambiri imatsegula valavu ya solenoid malinga ndi kutsegula ndi kutseka kosiyana pamene mphamvu yazimitsidwa. Nthawi zambiri kutsekedwa kwa solenoid valve, koyiloyo ikatha mphamvu, chida choyamba chimayendetsa pulagi ya valve yachiwiri pansi pa mphamvu ya electromagnetic mphamvu, ndipo madzi omwe ali pa chikho cha valve cha valve chachikulu amayenda kudzera mu valve yachiwiri, kuchepetsa kupanikizika. pa kapu ya valve ya valve yaikulu. Pamene kupanikizika kwa kapu ya valve ya valavu yaikulu kumachepetsedwa kukhala mtengo wina, chidacho chimayendetsa kapu ya valve ya valve yaikulu, ndipo imapangitsa kuti chikho cha valve cha valve chachikulu chitsegulidwe pogwiritsa ntchito kusiyana kwapakati, ndipo sing'anga ikuyenda. Koyiloyo ikazimitsidwa, mphamvu yamagetsi imasowa ndipo zida zimayambiranso chifukwa cha kulemera kwake.
Pa nthawi yomweyi, malingana ndi kuthamanga kwapakati, ma valve akuluakulu ndi achiwiri akhoza kutsekedwa mwamphamvu. Nthawi zambiri valavu yotseguka ya solenoid, koyilo itatha kupatsidwa mphamvu chifukwa cha kuyamwa, chitsulo chosuntha chimasunthira pansi, pulagi yothandizira valavu imatsitsidwa, valavu yothandizira imatsekedwa, kupanikizika mu chikho chachikulu cha valve kumakwera, pamene kupanikizika kumakwera kwambiri. mtengo wake, kusiyana kwapamwamba ndi kutsika kwa kapu ya valve yaikulu kumakhala ngati, chifukwa cha mphamvu yamagetsi yamagetsi, chitsulo chosuntha chimakankhira chikho chachikulu cha valve pansi, chimagwirizanitsa mpando waukulu wa valve, ndipo valavu imatsekedwa. Koyiloyo ikazimitsidwa, kuyamwa kwamagetsi ndi zero, pulagi yothandizira valavu ndi chitsulo chosuntha chimakwezedwa m'mwamba chifukwa cha kasupe, valavu yothandizira imatsegulidwa, kapu yayikulu ya valve imatsegulidwa.

Madzi amadzimadzi amayenda kudzera mu valve yothandizira, kuchepetsa kuthamanga kwa chikho chachikulu cha valve. Pamene kupanikizika pa chikho chachikulu cha valve kumachepetsedwa kukhala mtengo wina, kusiyana kwapakati kumagwiritsidwa ntchito kukankhira chikho chachikulu cha valve, valavu yaikulu imatsegulidwa, ndipo sing'anga ikuyenda.

Valve ya cartridge

Mfundo yogwirira ntchito ndi mawonekedwe a cartridge valve
Valve ya cartridge ndi mtundu wa valve yosinthira yomwe imagwiritsa ntchito mafuta ochepa owongolera kuti azitha kuyendetsa mafuta ambiri. Ndilo gawo lalikulu lowongolera la valve ya taper yomwe imayikidwa mu chipika chamafuta, motero dzina la cartridge valve.

Mavavu a cartridge tsopano amagawidwa m'magulu awiri: mtundu woyamba ndi valavu ya cartridge yachikhalidwe, yomwe idawonekera m'ma 1970 ndipo imagwiritsidwa ntchito makamaka pakuthamanga kwambiri komanso nthawi zambiri zotuluka. Sikoyenera kuyenda pang'ono pansi pa njira 16. Valavu ya cartridge simangozindikira ntchito zosiyanasiyana za valve wamba ya hydraulic, komanso imakhala ndi ubwino wokana kuyenda pang'ono, kuthamanga kwakukulu, kuthamanga kwachangu, kusindikiza bwino, kupanga kosavuta, ntchito yodalirika ndi zina zotero. Mtundu wachiwiri ndi valavu ya cartridge yopangidwa mofulumira pamaziko a valavu yachitetezo mu valavu yamitundu yambiri yamakina omanga, omwe amangopanga kusowa kwa kapu ya cartridge ya cartridge yomwe si yoyenera kuyenda pang'ono, makamaka zochitika zazing'ono zoyenda. The screw cartridge valve ili ndi ntchito zosiyanasiyana zowongolera, ndipo gawo limodzi limalowetsedwa mu chipika chowongolera ndi mtundu wa ulusi wa screw, ndipo kapangidwe kake ndi kakang'ono kwambiri komanso kophatikizika. Kuphatikiza pa kusiyana kwa kayendetsedwe kake, ili ndi pafupifupi ubwino wonse wa valve cartridge ya cap plate, ndipo ingagwiritsidwe ntchito kwambiri m'madera osiyanasiyana omwe amafunikira kulamulira kwa hydraulic kwa kuyenda kochepa.

Chifukwa cha mawonekedwe osavuta, ntchito yodalirika komanso kukhazikika kwapamwamba kwa valavu ya cartridge, ndiyoyenera kuphatikizira ma hydraulic system, kuchepetsa kwambiri cholumikizira cha payipi ndi kutayikira, kugwedezeka, phokoso ndi zolakwika zina zomwe zimayambitsidwa ndi payipi, ndipo zimatha kwambiri. kuchepetsa kukula ndi khalidwe la kuthamanga kwakukulu, kuthamanga kwambiri komanso dongosolo la hydraulic yovuta kwambiri.
