Lub Valve Plug Valve Hauv Asphalt sib tov chaw nres tsheb yog ib daim kaw lossis plunger-puab teb valve. Los ntawm kev sib hloov 90 degrees, channel chaw nres nkoj ntawm lub valve ntsaws yog tib yam li lossis sib cais los ntawm channel chaw nres nkoj ntawm lub cev channel ntawm lub cev lub cev qhib lossis kaw. Nws yog siv dav. Nyob rau hauv cov roj ua teb excavation, tsheb thauj mus los thiab muab cov khoom siv hluav taws xob, cov qub kuj tseem xav tau hauv Asphalt sib tov nroj tsuag.

Tus ntsaws ntawm cov ntsaws Valve hauv cov chaw nres tsheb asphalt sib xyaw ua ke yog cylindrical lossis conical. Nyob rau hauv ib lub cylindrical valve plug, cov channel feem ntau cov duab sib dhos; Nyob rau hauv conical valve plug, cov channel yog trapezoidal. Cov duab no ua rau cov qauv ntawm cov ntsaws valve lub teeb, uas haum rau thaiv thiab txuas cov nruab nrab thiab hloov cov ntws.
Txij li thaum lub zog ntawm cov chaw sib khi ntawm lub ntsaws valve muaj qhov cuam tshuam tas li thaum qhib qhov kev sib cuag, nws tuaj yeem siv rau kev tshaj tawm nrog kev raug tshem tawm. Tsis tas li ntawd, lwm qhov tseem ceeb ntawm lub plug lub valve yog tias nws yooj yim hloov kho cov qauv hluav taws xob, yog li muaj plaub qhov sib txawv raws li qee qhov sib txuas ntxiv uas xav tau hauv cov khoom siv.
Lub ntsaws valve ntawm asphalt sib tov cog yog haum rau cov haujlwm nquag vim tias nws tau yooj yim thiab yooj yim qhib thiab kaw. Nws tseem ua rau cov kua dej tsis yeem, cov qauv yooj yim, lub teeb me me, kev ua kom yuag me me, kev ua tau yooj yim, thiab tsis muaj kev co. , cov suab nrov tsawg thiab lwm yam zoo.
Thaum cov ntsaws lub valve yog siv rau hauv asphalt sib tov cog, nws tsis txwv los ntawm txoj kev sib txuas, thiab ntws tawm ntawm nruab nrab tuaj yeem yog ib qho, uas ntxiv txhawb nws siv hauv cov cuab yeej. Ib qho ntxiv, nws kuj tseem tuaj yeem siv dav hauv kev lag luam petrochemical, kev lag luam tshuaj, roj, roj av, hvac kev lag luam thiab kev lag luam dav dav.
