Kos lub valve, tseem hu ua check valve, ib lub pob ntws valve, kos lub valve lossis kos valve, nws lub luag haujlwm yog kom ntseeg tau tias qhov nruab nrab hauv lub raj xa hluav taws xob tsis muaj ntws rov qab. Qhov qhib thiab kaw ntawm daim tshev valve yog nyob ntawm qhov kev quab yuam ntawm qhov nruab nrab kom qhib thiab kaw. Kos valve belongs rau automatic valve cov khoom lag luam, kos valve tsuas tso cai rau nruab nrab ntws hauv ib qho kev coj ntawm lub raj xa dej los siv, tiv thaiv qhov tshwm sim ntawm nruab nrab ntws rov qab. Nws muaj ntau ntawm cov ntawv thov, thiab tuaj yeem siv hauv qhov loj thiab me me ntsuas, ntau yam tshaj tawm thiab chaw nres tsheb fais fab loj cov hluav taws xob.
Lub hauv paus ntsiab lus ntawm kos valve: kos valve qhib yog hais txog kev cia siab rau nruab nrab ntws mus qhib lub disc, tib qho laj thawj ntawm nruab nrab ntws rov qab los txhawb lub disc thiab kaw, kos valve tseem hu ua kos valve, seem-seem valve. , thim rov qab valve thiab rov qab siab valve. Lub luag haujlwm tseem ceeb ntawm lub valve yog los tiv thaiv qhov thim rov qab ntawm qhov nruab nrab, los tiv thaiv qhov thim rov qab ntawm lub twj tso kua mis thiab tsav lub zog thiab qhov paug tawm ntawm ntim nruab nrab. Nws kuj tseem siv rau kev tiv thaiv kev nyab xeeb hauv cov koom haum pabcuam qhov twg lub siab tuaj yeem siab tshaj qhov siab ntawm qhov system.
Kuaj valve kev faib tawm: kos valve yog tsuas yog siv los tiv thaiv kev siv cov xov xwm ntws rov qab hauv cov raj xa dej. Hauv qab lub teeb valve thiab daim nqe nqe lub npov (valve bill) tseem muaj nrog daim tshev valve system.
Kos valve tuaj yeem muab faib ua hom nqa, viav vias hom, disc hom peb:
Hom nqa tau muab faib ua ob feem ntsug thiab kab rov tav 2 yam, cov qauv nqa tau txav raws txoj kab nruab nrab.
Piv txwv:
(1) Nqa hom ntsiag to kos valve siv rau hauv kev tso dej thiab xa dej ua haujlwm engineering zoo ua tau ntawm lub kav dej; Nyob rau tib lub sijhawm, nws tuaj yeem ntsia tau rau ntawm qhov hluav taws xob ntawm lub twj tso kua mis, thiab cov yeeb nkab sib txuas nrog qhov ntsuas kub siab (PN2.5Mpa) yog cov khoom tseem ceeb ntawm kev cuam tshuam dej tsis ua hauj lwm kos valve.
(2) Lifting hom silencer kos valve yog haum rau lub tsev siab siab ua haujlwm dej thiab tso dej tawm thiab lub qhov hluav taws xob ntawm lub twj tso kua mis, tsis tsim nyog rau cov kav dej phwj ntau zaus.
(3) Kab rov tav kos valve yog tsim nyog rau kev ua kom dhia dej, dej ntws tawm, dej phwj tuaj, tshwj xeeb tshaj yog rau dej phwj tuaj thiab sludge.
Lub viav vias tau muab faib ua ib hom-valve hom, ob chav-valve hom thiab ntau-valve yam. Lub viav vias hom qauv yog xaiv raws li qhov nruab nrab ntawm cov qauv sib tsoo.
Piv txwv:
(1) Xaiv qhib hom roj hmab kos valve yog siv rau hauv nroog cov dej xa hluav taws xob nyob hauv nroog, tsis tsim nyog rau cov kav dej phwj tuaj nrog ntau qhov kev tso.
(2) Viav vias hom ib qho sib tw tsaws valve muaj qhov sib txawv siv ntau, tuaj yeem ntsia tau rau hauv cov dej thiab tso dej, roj av, tshuaj lom neeg, metallurgy, kev lag luam thiab lwm cov raj xa dej, lub sijhawm tsim nyog tshaj rau kev txwv chaw.
Tus qauv phaj yog ncaj-dhau.
Piv txwv:
(1) Disc ob chav disc kos valve yog siv dav hauv tsev siab xa dej rau raj xa dej, muaj cov tshuaj tiv thaiv corrosive thiab dej phwj hauv kev siv cov kua yeeb nkab network.
(2) Viav vias hom ib qho sib tw tsaws valve muaj qhov sib txawv siv ntau, tuaj yeem ntsia tau rau hauv cov dej thiab tso dej, roj av, tshuaj lom neeg, metallurgy, kev lag luam thiab lwm cov raj xa dej, lub sijhawm tsim nyog tshaj rau kev txwv chaw.
Kab rov tav kos valve yog tsim nyog rau kev dhia dej, dej ntws tawm, nqus dej twj tso kua mis, tshwj xeeb tshaj yog rau dej phwj tuaj thiab sludge.
