Qhov sib txawv ntawm kev tswj ib feem ntawm lub twj tso kua mis sib txawv yog paub los ntawm hydraulic tag nrho choj los yog hydraulic ib nrab-choj, thiab lub hydraulic tag nrho choj los yog hydraulic ib nrab choj yog tsim los ntawm cov kua ua hauj lwm los yog cov kua kuj sib txawv. Yog li ntawd, nws yog ib qho tsim nyog yuav tau soj ntsuam cov kua ua kua thiab cov kav dej ua ntej.
Cov kua ua kua yog ib qho tshwm sim uas lub siab poob vim lub zog poob los ntawm kev sib txhuam ntawm cov kua dej thaum cov kua ntws los ntawm cov kav dej. Generalized kua tsis kam yog ib qho hydraulic valve uas tuaj yeem hloov qhov chaw ntws ntawm cov kua ntws los ua kom poob siab (tus yam ntxwv tsis kam) lossis nyob rau hauv rooj plaub ntawm qhov sib txawv siab, faib thiab kho tus nqi ntws (tswj cov yam ntxwv) thiab cov qauv zoo sib xws, xws li nyias-walled qhov, qhov luv luv, slender qhov, qhov khoob, thiab lwm yam, yog hu ua kua kuj. Cov kua ua kua tuaj yeem muab faib ua cov kab hluav taws xob tiv thaiv thiab hauv zos tsis kam. Txhua yam ua kua ua haujlwm yuav tsum ua kom txaus siab qhov sib npaug ntawm cov dej ntws. Los ntawm lub tswv yim dav no, nws tuaj yeem pom tau tias qhov tseem ceeb ntawm kev ua kua dej muaj xws li ob yam, puck yog nws cov yam ntxwv tsis kam (lub siab ua ntej thiab tom qab cov kua ua kua tuaj yeem sib txawv), thiab kev txwv tam sim no yog nws cov yam ntxwv tswj (hloov lub qhov loj ntawm cov kua kuj tuaj yeem hloov qhov ntws los ntawm).
Pib los ntawm cov haujlwm tseem ceeb ntawm ob yam ntawm cov kua ua kua, muaj ntau hom kev siv tam sim no.
1) Hydraulic choj (hydraulic ib nrab choj) ua kua ua kua.
2) Dynamic damping kua kuj.
3) Dynamic siab tawm tswv yim ua kua kuj.
4) Ntau yam tswj valve chaw nres nkoj:
① Feem ntau ruaj valve chaw nres nkoj (qhov chaw nres nkoj qhov chaw yog sib npaug rau thaj tsam ntawm txoj kev ntws)
② Qhov chaw nres nkoj dav dav dav dav (qhov siab tshaj plaws ntawm qhov chaw nres nkoj valve yog ntau dua lossis sib npaug rau qhov chaw ntws channel)
③ Cov kev taw qhia qhov chaw nres nkoj (chaw nres nkoj yog tsawg kawg yog 4 npaug ntawm qhov chaw nres nkoj siab tshaj plaws)
Liquid resistance tuaj yeem muab faib ua:
1) Tsau ua kua ua kua (tsis hloov qhib lossis aperture).
2) Adjustable kua kuj (tuaj yeem kho nws qhov qhib manually lossis los ntawm kev siv tshuab);
3) Controllable kua kuj (nws tuaj yeem tswj tau los ntawm kev tswj lub teeb liab los ntawm electromagnet, thiab lwm yam., nws qhov qhib tsis ncaj qha los ntawm cov tswv yim, tab sis los ntawm lub zog ntawm lub valve core).
