Lub hydraulic reversing valve ntawm asphalt sib tov nroj tsuag feem ntau tsis tau dhau los, tab siscub tsis muaj peev xwm ua tsis tiav, thiab lwm yam, thiab cov qauv kev kho mob yog ib qho txawv.

Yog tias lub hydraulic reversing valve tsis hloov theem nyob rau hauv lub sij hawm, feem ntau nws yog qhov tsim nyog daig hauv qhov xwm txheej ntawm tus mob pneumatic triplex thiab cov viscosity ntawm grease. Yog tias tsim nyog, cov roj lossis lwm qhov chaw tuaj yeem hloov.
Thaum siv sijhawm ntev, lub hydraulic reversing valve ntawm cov asphalt sib tov cog yog nquag rau kev puas tsuaj rau lub valve valve, ua rau muaj kev kub siab rau hauv lub valve. Nyob rau lub sijhawm no, lub nplhaib sib khi, lub rooj zaum valve thiab lub rooj loj-siab GATE yuav tsum tau hloov, lossis cov kev txhawb nqa hydraulic yuav tsum tau hloov nyob rau lub sijhawm.
Yog li ntawd, txhawm rau kom muaj ntau yam ntxiv txo tus nqi ntawm cov asphalt tov tsob nroj, nws kuj tseem yuav them sai sai rau kev saib xyuas ntawm cov tshuab thiab qhov chaw.
