Valve ya Hydraulic ndi gawo lodziwikiratu lomwe limayendetsedwa ndi mafuta oponderezedwa, limayendetsedwa ndi mafuta othamanga, omwe nthawi zambiri amaphatikizidwa ndi ma electromagnetic pressure valve, amatha kugwiritsidwa ntchito kuwongolera kutali kwamafuta a hydropower station, gasi, mapaipi amadzi.Amagwiritsidwa ntchito ngati clamping, control, lubrication ndi zina zozungulira mafuta.Pali mtundu wa zochita zachindunji ndi mtundu wa upainiya, mtundu wa upainiya wogwiritsa ntchito zambiri.Udindo wa hydraulic valve umagwiritsidwa ntchito makamaka kuchepetsa ndi kukhazikika kwa mphamvu ya mafuta a nthambi m'dongosolo, ndipo nthawi zambiri amagwiritsidwa ntchito popanga, kulamulira, kudzoza mafuta ndi maulendo ena amafuta.Pali mwachindunji kusuntha mtundu, kutsogolera mtundu ndi superposition mtundu.Chigawo chomwe chimagwiritsidwa ntchito pofalitsa ma hydraulic kuwongolera kuthamanga, kuyenda, ndi komwe kumadziwira.Valve yowongolera kuthamanga imatchedwa valve control valve, valve control valve imatchedwa valve control valve, ndipo kuwongolera, kutsika ndi kuwongolera kumatchedwa valavu yowongolera.Gulu la ma hydraulic valves: gulu ndi ntchito: valavu yothamanga ( valve yothamanga, valavu yoyendetsa liwiro, valavu ya diverter, valavu yosonkhanitsa, valavu yosonkhanitsa), valavu yamagetsi (valavu yothandizira, valavu yochepetsera, valavu yotsatizana, valavu yotsitsa), valavu yotsogolera ( valavu yamagetsi yamagetsi, valavu yosinthira pamanja, valavu yoyang'ana, valavu yoyang'anira ma hydraulic control)

Ma valve oyendetsa ndege amapezeka m'makonzedwe osiyanasiyana.Valavu yoyendetsa ndege yokhala ndi magawo atatu, yomwe imakhala ndi magawo awiri: valavu yoyendetsa ndi valavu yayikulu.

Vavu yoyendetsa taper, dzenje lotsekeka (bowo lokhazikika) pa spool yayikulu ndi kukakamiza kowongolera kasupe palimodzi kumapanga woyendetsa wa theka la mlatho wapang'onopang'ono wowongolera mayankho olakwika, omwe ali ndi udindo wopereka chiwongolero chachikulu cholamula pambuyo pa valavu yoyendetsa. kuwongolera kuthamanga kuchipinda chapamwamba cha spool yayikulu ya valve.Spool yayikulu ndikufanizira kwa loop yayikulu yolamulira.Nkhope yapamwamba imakhala ngati mphamvu yolamulira ya spool yaikulu, pamene nkhope yapansi yapansi imakhala ngati kupanikizika kwapakati pa chingwe chachikulu ndikuchita ngati mphamvu yoyankha.Mphamvu yotsatiridwayo imatha kuyendetsa spool, kusintha kukula kwa doko losefukira, ndipo pamapeto pake kukwaniritsa cholinga chowongolera ndikuwongolera kupanikizika kwa inlet P1.

YF mtundu wa magawo atatu oyendetsa ma valve oyendetsa ndege Chithunzi 1-(- valavu ya taper (valavu yoyendetsa); 2 - Mpando wa cone 3 - chivundikiro cha valve; 4 - Thupi la valve; 5 - dzenje lotayirira; 6 - valavu yayikulu; 7 - Main mpando 8 - kasupe wamkulu wa valve 9 - kuwongolera kuthamanga (vavu woyendetsa) masika 10 - kukonza zitsulo;
