Hydraulic directional tswj li qub feem ntau muab piv rau lwm hom kev tswj lub valve, xws li kos li qub thiab shuttle li qub. Kos li qub tsuas tso cai rau unidirectional ntws ntawm cov roj thiab tsis tuaj yeem ua kev hloov pauv; Yog li ntawd, cov kev taw qhia tswj li qub yog qhov tsim nyog rau cov tshuab uas xav tau kev tswj hwm bidirectional. Shuttle li qub yog li qub uas tau xaiv qhov siab - siab roj txoj hauv kev thiab feem ntau siv rau hauv kev tswj cov logic, tab sis lawv tsis muaj lub peev xwm hloov pauv hloov tau.
Piv nrog rau cov hluav taws xob lossis pneumatic tswj kev tswj li qub, hydraulic directional tswj li qub muaj qhov zoo ntawm lub zog siab ceev thiab kev ntseeg siab. Cov tshuab hydraulic tuaj yeem xa cov quab yuam loj thiab lub zog, ua rau lawv haum rau cov tshuab hnyav thiab siab -load daim ntawv thov. Hluav taws xob tswj cov li qub feem ntau yog siv nyob rau hauv qis - lub tshuab fais fab, muab cov lus teb ceev tab sis muaj peev xwm thauj khoom tsawg; pneumatic directional tswj li qub yog tsim rau lub teeb loads thiab siab - daim ntawv thov ceev, tab sis lawv qhov tseeb thiab ruaj khov yog qis dua rau cov tshuab hydraulic vim yog huab cua compressibility.
Hais txog tus nqi, kev nqis peev thawj zaug hauv hydraulic directional tswj li qub yuav siab dua, tab sis vim lawv cov kav ntev thiab lub neej ntev, cov nqi kho mob qis dua - siv sijhawm ntev. Piv txwv li, lub solenoid ntawm lub electromagnetic directional tswj valve yuav tsum tau hloov lub sij hawm, tab sis lub valve lub cev feem ntau yuav kav ntev li ntau xyoo. Piv txwv li, lub cev muaj zog thiab cov khoom siv hluav taws xob ntawm cov hluav taws xob taw qhia li qub yuav ua rau muaj kev puas tsuaj ntau dua thiab yuav tsum tau saib xyuas ntau zaus.
