Ib qho tseem ceeb kom zoo dua ntawm cov rooj vag li qub yog lawv qhov qis qis qis. Thaum qhib tag nrho, lub rooj vag li qub muab txoj hauv kev ncaj nraim rau cov dej ntws, tso cai rau qhov siab tshaj plaws thiab qis qis. Tsis tas li ntawd, lub rooj vag li qub tau paub txog lawv lub peev xwm kaw ntom nti, kom ntseeg tau tias tsis muaj qhov xau tshwm sim thaum lub valve kaw tag nrho. Qhov no ua rau lawv tsim nyog rau cov ntawv thov uas xav tau kev ua haujlwm tsis muaj paug.
Roj hmab zaum rooj vag li qubyog siv nyob rau hauv ntau yam kev lag luam, xws li roj thiab roj, kev kho dej, tshuaj thiab hluav taws xob. Hauv kev lag luam roj thiab roj, lub rooj vag li qub yog siv los tswj cov dej ntws ntawm cov roj av thiab cov nkev hauv cov kav dej. Cov chaw kho dej siv cov rooj vag li qub los tswj cov dej ntws los ntawm cov txheej txheem sib txawv. Lub rooj vag li qub kuj tseem siv tau rau hauv cov chaw tsim hluav taws xob, tso cai rau kev tswj cov dej ntws los yog cov dej txias hauv cov tshuab turbine.
Thaum lub rooj vag valve muaj ntau qhov zoo, lawv kuj muaj qee qhov kev txwv. Ib qho tsis zoo yog tias lawv ua haujlwm qeeb qeeb piv rau lwm hom li qub. Lub rooj vag li qub xav tau ob peb lub log ntawm tes los yog tus actuator kom qhib lossis kaw, uas tuaj yeem siv sijhawm ntev heev. Tsis tas li ntawd, lub rooj vag li qub muaj qhov cuam tshuam rau kev puas tsuaj vim muaj cov khib nyiab los yog cov khib nyiab nyob hauv txoj kev ntws, ua rau lub rooj vag los yog daig.
Hauv cov ntsiab lus, lub rooj vag li qub yog ib feem tseem ceeb ntawm cov txheej txheem kev lag luam uas xav tau kev tswj xyuas cov kua dej kom meej. Nws txhim khu kev qha sealing muaj peev xwm thiab tsawg kawg siab poob ua rau nws indispensable nyob rau hauv ntau yam lag luam. Txawm hais tias lawv muaj qee qhov kev txwv, lub rooj vag li qub tseem tau siv dav vim lawv cov txiaj ntsig thiab kev ua tau zoo hauv kev tswj cov dej ntws.
