Kos lub valve, tseem hu ua ib-txoj kev valve, kos valve, rov qab siab valve, hom valve no tau qhib thiab kaw los ntawm lub zog tsim los ntawm qhov ntws ntawm qhov nruab nrab nws tus kheej hauv cov kav dej, thiab belongs rau lub valve tsis siv neeg. Kev ua haujlwm ntawm cov tshev valve yog los tiv thaiv qhov rov qab ntawm qhov nruab nrab, qhov rov qab tig ntawm lub twj tso kua mis thiab nws lub cev muaj zog, thiab kev tawm ntawm qhov nruab nrab hauv lub thawv. Muab ob npaug rau-phaj kos valve yog ib hom kev kos valve. Los ntawm kev xaiv cov khoom sib txawv, lub wafer check valve tuaj yeem siv rau hauv dej, chav dej, roj hauv petrochemical, metallurgy, hluav taws xob fais fab, lub teeb kev lag luam, khoom noj khoom haus thiab lwm yam lag luam. , nitric acid, acetic acid, muaj zog oxidizing nruab nrab thiab urea thiab lwm yam xov xwm.
Lub viav vias kos valve txais yuav lub pob zeb ua ke ntawm caj npab 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 siv nyob rau hauv nruab nrab flange, lub zuag qhia tag nrho Yog tsis muaj to taw tes, tshem tawm qhov muaj peev xwm ntawm valve to. Kev sib txuas ntawm lub caj npab rocker thiab lub disc ntawm lub viav vias kos valve txais cov qauv kev sib txuas kheej kheej, kom lub disc muaj qee qhov kev ywj pheej nyob rau hauv thaj tsam ntawm 360 degrees, thiab muaj cov txiaj ntsig zoo. Nws yog tsuas yog siv rau hauv roj av, tshuaj, tshuaj, chiv, thiab lwm yam., hluav taws xob thiab lwm yam kav dej. Haum rau cov xov xwm huv, tsis haum rau cov xov xwm uas muaj cov khoom siv thiab cov viscosity siab
