A valavu ya hydraulickwenikweni ndi "chipangizo chosinthika cha hydraulic resistance", palibenso china, chocheperapo. Ma valve onse a hydraulic ayenera kukhala okhoza "kusintha hydraulic resistance", ndipo akhoza kuchita izi, popanda kupatula. Kuyambira pazimenezi, zimakhala zosavuta komanso zomveka kuti mumvetse ma valve a hydraulic, makamaka, ma valve ophatikizana m'makina omanga, ma valve ena a hydraulic okhala ndi zovuta, mu dongosolo la hydraulic kwenikweni, akhoza kukhala ndi zotsatira zosiyanasiyana pansi pa zochitika zosiyanasiyana zogwirira ntchito Ndipo chodabwitsa.

Ndi chitukuko chaukadaulo wama hydraulic masiku ano, mtundu wavalavu ya hydraulic ndi zowala. Mayiko osiyanasiyana komanso makampani osiyanasiyana m'dziko lomwelo ali ndi magulu osiyanasiyana a ma valve a hydraulic. Mkonzi wa nkhaniyi akufotokoza mwachidule kutengera mitundu ya ma valve omwe amapezeka pamsika kuti afotokoze:

1. Mavavu a njira imodzi amatha kugawidwa m'mavavu wamba anjira imodzi ndi ma hydraulic oyendetsedwa ndi njira imodzi. Ma valve wamba anjira imodzi amangolola kuti madzi azitha kudutsa mbali imodzi, ndipo valavu yoyendetsedwa ndi ma hydraulic yanjira imodzi imathanso kuyenderera mobwerera kumbuyo chifukwa cha kukakamizidwa kwa woyendetsa.
2. Valve ya shuttle imatha kulandira madzi amadzimadzi kuchokera kuzinthu ziwiri zosiyana ndikupereka kupanikizika kwakukulu kumalo amodzi. Ma valve a shuttle nthawi zambiri amagwiritsidwa ntchito pamayendedwe ozindikira katundu ndi mabwalo amafuta a brake. Kuphatikizapo mtundu wa mpira, mtundu wa valve ya mpando ndi mtundu wa valve spool.
3. Valavu yowonongeka imakhala ndi ntchito zosiyanasiyana pazochitika zosiyanasiyana. Mwachitsanzo, pamapampu othamanga kwambiri, valavu yothamanga imagwiritsidwa ntchito kusunga mphamvu ya hydraulic system (ndiko kuti, kuthamanga kwa pampu ya hydraulic) mosalekeza, ndikusefukira kutuluka kwa pampu ya hydraulic kubwerera. thanki. Panthawi imeneyi, valavu yowonongeka imagwiritsidwa ntchito pofuna kupanikizika kosalekeza. Kugwiritsa ntchito valve.
4. Valavu yochepetsera mphamvu ndi valavu yoyendetsera mphamvu yomwe imagwiritsa ntchito madzi amadzimadzi kuti adutse pamtunda kuti apange kutayika kwa mphamvu, kotero kuti kuthamanga kwa kutuluka kumakhala kochepa kusiyana ndi kulowetsedwa. Malingana ndi zofunikira zosiyana siyana, valavu yochepetsera kuthamanga ikhoza kugawidwa kukhala valve yochepetsera nthawi zonse, valavu yochepetsera yokhazikika komanso valavu yochepetsera kusiyana.
5. Ntchito ya valve yotsatizana ndiyo kugwiritsira ntchito mphamvu ya mafuta ngati chizindikiro chowongolera kuti chiwongolere ndi kutuluka kwa dera la mafuta. Amatchulidwa chifukwa amagwiritsidwa ntchito kuwongolera machitidwe a ma actuators angapo. Ma valve otsatizana amagawidwa m'magulu ochita molunjika komanso oyendetsa ndege.
6. Valve yotsutsana ndi imodzi mwazinthu zosadalirika kwambiri pamakampani opanga ma hydraulic. Anthu ambiri amakonda kusokoneza chisankho cha valavu, choncho amakana kusankha.
