Lub ntsaws valve yog lub valve nyob rau hauv cov duab ntawm ib tug kaw los yog plunger. Tom qab tig 90 degrees, lub channel qhib ntawm lub valve ntsaws yog tib yam li los yog sib cais los ntawm cov channel qhib ntawm lub valve lub cev kom tiav qhib lossis kaw. Nws yog dav siv nyob rau hauv oilfield excavation, tsheb thauj mus los thiab refining khoom, thiab xws li li qub yuav tsum tau nyob rau hauv asphalt mixing nroj tsuag.

Lub valve ntsaws ntawm lub ntsaws valve hauv asphalt sib xyaw cog tuaj yeem ua cylindrical lossis conical. Nyob rau hauv lub cylindrical valve ntsaws, cov channel feem ntau yog cov duab plaub; Nyob rau hauv lub conical valve plug, lub channel yog trapezoidal. Cov duab no ua rau cov qauv ntawm lub ntsaws valve lub teeb thiab tsim nyog rau kev thaiv thiab txuas xov xwm thiab kev sib txawv.
Txij li thaum lub zog ntawm lub sealing nto ntawm lub ntsaws valve muaj cov nyhuv txhuam, thiab thaum qhib tag nrho, nws tuaj yeem zam kev sib cuag nrog qhov nruab nrab txav, yog li nws feem ntau siv tau rau kev tshaj tawm nrog cov khoom raug tshem tawm. Tsis tas li ntawd, lwm qhov tseem ceeb ntawm lub ntsaws valve yog nws yooj yim rau kev hloov mus rau ntau qhov qauv, kom ib lub valve tuaj yeem tau txais ob, peb, lossis plaub qhov sib txawv ntawm cov dej ntws, uas tuaj yeem yooj yim rau kev teeb tsa ntawm cov kav dej. , txo tus nqi ntawm cov li qub thiab qee cov khoom siv sib txuas uas xav tau hauv cov khoom siv.
Lub ntsaws valve ntawm asphalt mixing nroj tsuag yog haum rau kev ua haujlwm nquag vim nws qhib thiab kaw yooj yim thiab ceev. Nws kuj muaj qhov zoo ntawm cov kua dej me me, cov qauv yooj yim, qhov loj me, lub teeb yuag, yooj yim txij nkawm, kev sib khi zoo, tsis muaj kev vibration, thiab suab nrov tsawg.
Thaum lub ntsaws valve siv nyob rau hauv asphalt mixing nroj tsuag, nws yuav tsis raug constrained los ntawm cov kev taw qhia ntawm lub cuab yeej, thiab cov ntws kev taw qhia ntawm qhov nruab nrab yuav ua tau ib yam, uas ntxiv txhawb nws siv nyob rau hauv cov khoom. Qhov tseeb, ntxiv rau cov lus hais saum toj no, lub ntsaws valve tseem tuaj yeem siv dav hauv petrochemical, chemical, thee gas, natural gas, liquefied petroleum gas, HVAC cov hauj lwm thiab kev lag luam.
