Lub proportional valve yog hu ua electro-hydraulic proportional valve, uas yog ib hom hydraulic valve uas hloov cov input hluav taws xob teeb liab mus rau hauv lub zog los yog hloov pauv proportionally, thiaj li mus txuas ntxiv tswj lub siab, ntws thiab lwm yam tsis. Lub proportional valve yog tsim los ntawm DC proportional electromagnet thiab hydraulic valve. Qhov hydraulic valve yog me ntsis txawv ntawm cov hydraulic valve dav dav, thiab DC proportional electromagnet txawv ntawm cov electromagnet siv nyob rau hauv lub dav solenoid valve, thiab cov tso zis tawm thiab nqus cov zis yuav tau proportional rau cov muab tam sim no los ntawm kev siv proportional electromagnet. . Raws li nws cov kev tswj tsis tau muab faib ua proportional siab valve, proportional flow valve, proportional direction valve peb pawg.
Nrog rau txoj kev loj hlob ntawm hydraulic kis tau tus mob thiab hydraulic servo systems, ib co hydraulic systems uas yuav tsum tau tas mus li kev tswj ntawm lub siab, ntws thiab kev taw qhia yam tsis muaj siab tswj qhov tseeb tau tshwm sim nyob rau hauv ntau lawm xyaum. Txij li cov khoom siv hydraulic zoo tib yam tsis tuaj yeem ua tiav txaus kom muaj qee qhov kev xav tau servo, thiab kev siv cov khoom siv hluav taws xob-hydraulic servo li qub yog qhov khib nyiab heev vim tias cov kev tswj xyuas qhov tseeb tsis siab, qhov kev faib ua feem ntawm cov khoom siv hydraulic (hloov tswj) thiab servo valve (kev tswj tsis tu ncua) tau tsim nyob rau hauv xyoo tas los no.
Electro-hydraulic proportional control valve (hu ua proportional valve) yog ib hom pheej yig electro-hydraulic tswj valve nrog kev ua haujlwm zoo los tiv thaiv kev ua qias tuaj. Txoj kev loj hlob ntawm proportional valve kev paub ob txoj kev, ib tug yog los hloov phau ntawv hloov kho tswv yim mechanism ntawm cov tsoos hydraulic valve nrog proportional electromagnet, nyob rau hauv lub hauv paus ntawm cov tsoos hydraulic valve: kev loj hlob ntawm ntau yam proportional kev taw qhia, siab thiab ntws li qub; Qhov thib ob yog tias qee tus thawj electro-hydraulic servo valve manufacturers tau tsim tom qab txo qhov tsim thiab kev tsim khoom raug raws li lub hauv paus ntawm electro-hydraulic servo li qub.
