A valve ea hydraulicHa e le hantle ke "sesebelisoa se nang le hydraulic resistance" feela, ha ho letho le leng, le ka tlaase ho moo.Li-valve tsohle tsa hydraulic li tlameha ho khona ho "fetola hydraulic resistance", 'me li ka etsa sena feela, ntle le mokhelo.Ho qala ho tloha mohloling ona, ho batla ho le bonolo le ho pharaletseng ho utloisisa li-valve tsa hydraulic, haholo-holo, li-valve tse ling tse kopantsoeng mechine ea kaho, li-valve tse ling tsa hydraulic tse nang le mehaho e rarahaneng, tsamaisong ea sebele ea hydraulic, e ka 'na ea e-ba le liphello tse sa tšoaneng tlas'a maemo a fapaneng a ho sebetsa Le ketsahalo.

Ka nts'etsopele ea theknoloji ea hydraulic kajeno, mofuta oavalve ea hydraulic ea phatsima.Linaha tse fapaneng esita le lik'hamphani tse fapaneng naheng e le 'ngoe li na le lihlopha tse fapaneng tsa li-valve tsa hydraulic.Mohlophisi oa sengoloa sena o etsa kakaretso e khuts'oane ho latela mefuta ea li-valve tse tloaelehileng 'marakeng bakeng sa litšupiso:

1. Li-valve tsa tsela e le 'ngoe li ka aroloa ka li-valve tse tloaelehileng tsa tsela e le' ngoe le li-valve tsa tsela e le 'ngoe tse laoloang ke hydraulic.Li-valve tse tloaelehileng tsa tsela e le 'ngoe li lumella feela hore metsi a phalle ka tsela e le' ngoe, 'me valve ea tsela e le 'ngoe e laoloang ke hydraulic e ka boela ea phalla ka morao tlas'a khatello ea mofofisi.
2. Sesepa sa shuttle se ka fumana phallo ea metsi ho tloha mehloling e 'meli e fapaneng' me ea fana ka khatello e phahameng ka ho fetisisa sebakeng se le seng.Li-valve tsa Shuttle hangata li sebelisoa lipotolohong tse utloang mojaro le lipotolohong tsa oli ea brake.Ho kenyelletsa mofuta oa bolo, mofuta oa valve ea setulo le mofuta oa valve ea spool.
3. Valofo ea ho phalla e na le ts'ebeliso e fapaneng liketsahalong tse fapaneng.Ka mohlala, tsamaisong ea taolo ea lebelo la pompo ea ho phalla, valve ea ho phalla e sebelisoa ho boloka khatello ea hydraulic system (ke hore, khatello ea ho tsoa ha pompo ea hydraulic) e sa khaotse, 'me e phalla ho phalla ho feteletseng ha pompo ea hydraulic ho khutlela ho tanka.Nakong ena, valve ea ho phalla e sebelisoa bakeng sa khatello e sa khaotseng.Tšebeliso ea li-valve.
4. Sekhahla sa ho fokotsa khatello ke valve ea ho laola khatello e sebelisang metsi a phallang ho phalla ka lekhalo ho hlahisa tahlehelo ea khatello, e le hore khatello ea ho tsoa e fokotsehe ho feta khatello e kenang.Ho ea ka litlhoko tse fapaneng tsa ho fetola, valve ea ho fokotsa khatello e ka aroloa ka sekhahla sa ho fokotsa khatello e sa khaotseng, sekhahla se fokolang sa ho fokotsa sekhahla le sekhahla se fokolang sa ho fokotsa sekhahla.
5. Mosebetsi oa valve ea tatellano ke ho sebelisa khatello ea oli e le pontšo ea ho laola ho laola le ho tima potoloho ea oli.E bitsoa hobane e sebelisoa ho laola tatellano ea liketso tsa li-actuator tse ngata.Li-valve tsa tatellano li arotsoe ka mefuta e sebetsang ka ho toba le ea lifofane.
6. The counterbalance valve ke e 'ngoe ea lihlahisoa tse sa tšepiseng ho feta indastering ea hydraulic.Batho ba bangata ba rata ho thatafatsa khetho ea valve ea ho leka-lekana, kahoo ba hana ho etsa khetho.
