API 6D viav vias kos valve tiv thaiv qhov nruab nrab hauv cov kav dej los ntawm ntws rov qab.lub valve uas qhib los yog kaw los ntawm qhov ntws thiab quab yuam ntawm qhov nruab nrab los tiv thaiv qhov nruab nrab ntawm qhov ntws rov qab yog hu ua check valve.Kos li qub yog nyob rau hauv qeb ntawm tsis siv neeg li qub, uas yog tsuas yog siv nyob rau hauv pipelines qhov twg nruab nrab ntws nyob rau hauv ib tug kev taw qhia, thiab tsuas yog cia lub nruab nrab ntws nyob rau hauv ib tug kev taw qhia los tiv thaiv kev raug mob.Hom valve no feem ntau yuav tsum tau teeb tsa kab rov tav hauv cov kav dej.
Lub viav vias kos valve txais cov qauv tsim hauv rocker viav vias.Tag nrho cov qhib thiab kaw qhov chaw ntawm lub valve yog ntsia rau hauv lub valve lub cev, thiab tsis txhob nkag mus rau lub valve lub cev.Tsuas yog lub sealing gasket thiab sealing nplhaib ntawm nruab nrab flange, tag nrho tsis muaj qhov to, tiv thaiv qhov ua tau ntawm valve to.Lub viav caj npab ntawm lub viav vias kos valve txais cov qauv kev sib txuas kheej kheej ntawm kev sib txuas ntawm caj npab rocker thiab lub valve nrov plig plawg, kom lub valve nrov plig plawg muaj qee qhov kev ywj pheej nyob rau hauv thaj tsam ntawm 360 degrees, thiab muaj qhov tsim nyog txoj haujlwm. nyiaj pab.
Los ntawm kev xaiv cov khoom sib txawv, lub viav vias kos valve tuaj yeem siv rau ntau yam xov xwm xws li dej, chav dej, roj, nitric acid, acetic acid, muaj zog oxidizing media thiab urea.Feem ntau yog siv rau hauv cov kav dej xws li roj av, tshuaj, tshuaj, chiv, thiab hluav taws xob.
