Kugawika kwa ma valve othandizira

Malinga ndi kapangidwe ndi ntchito ya valavu yothandizira, imatha kugawidwa m'mitundu iyi:
Valve yochepetsera kuthamanga
Valavu yothandizira kupanikizika imagwiritsidwa ntchito makamaka kuchepetsa kuthamanga kwambiri mu hydraulic system. Pamene kuthamanga kwa hydraulic system kumaposa
Mtengo wokonzedweratu ukakhazikitsidwa, spool imatsegula doko losefukira, ndipo kukakamiza kopitilira mtengo wokonzedweratu kudzatulutsidwa kudzera padoko losefukira. Nthawi zambiri amagwiritsidwa ntchito mu machitidwe
Ndikofunikira kuteteza kupanikizika kwakukulu kwa zigawo za hydraulic kuti mupewe kuwonongeka kwa zigawo za hydraulic chifukwa chazovuta kwambiri za hydraulic pressure.
Valavu yopumira nthawi zonse
Valavu yopumira nthawi zonse imagwiritsidwa ntchito kuchepetsa kutuluka kwamadzimadzi ndikuletsa kuthamanga kwambiri mu hydraulic system kuti isawononge zida za hydraulic. Pamene kutuluka mu dongosolo kupitirira mtengo wokonzedweratu, spool idzatsegula doko la kusefukira, ndipo kutuluka kopitirira mtengo wokonzedweratu kudzatulutsidwa kudzera pa doko la kusefukira. Nthawi zambiri amagwiritsidwa ntchito m'makina omwe kutuluka kwamadzimadzi kumayenera kukhala kochepa, monga makina opangira jakisoni, makina odulira ndi makina osindikizira a hydraulic.
Tiyeni tidikire.
Valve yothandizira magawo awiri
Valve yothandizira malo awiri ndi valavu yosinthira pamanja, potembenuza pamanja chipangizo chosinthira, mutha kusintha kuyika kwapakati kwa valavu. Malinga ndi mphamvu yojambulira yosiyana, spool idzatsegula kapena kutseka doko losefukira, motero kuzindikira kupanikizika kapena malire othamanga mu hydraulic system. Amagwiritsidwa ntchito nthawi zambiri pamene kuwongolera pamanja kapena kuthamanga kumafunika.
Chidule mwachidule
Valve yothandizira ndi chinthu chodziwika bwino cha hydraulic control element, chomwe chimagwiritsidwa ntchito kwambiri kuchepetsa kapena kuwongolera kuthamanga kwambiri mu hydraulic system. Mfundo yake yogwirira ntchito ndi kudzera pakutsegula ndi kutseka kwa spool, yomwe idzapitirira kuthamanga kwa hydraulic preset kapena mzere wothamanga.
Kuphatikiza pa dongosololi, potero kuteteza zigawo za hydraulic kuchokera ku kuthamanga kwakukulu kapena kuwonongeka koyenda.
Mitundu yosiyanasiyana ya ma valve operekera chithandizo imagwiritsidwa ntchito pazochitika zosiyanasiyana za hydraulic system, ndipo ntchito yawo yogwirira ntchito ndi magawo ake amasiyananso. Kwa opangira ma hydraulic system ndi ogwira ntchito yosamalira, kusankha koyenera ndi kuwongolera valavu yothandizira ndikofunikira kwambiri.
