Flanged npauj npaim valve yog ib daim ntawv heev ntawm npauj npaim valve thiab yog qhov ntau yam.
1. Flanged npauj npaim li qub yog siv rau hauv cov raj xa khoom ntau lawm. Nws lub luag haujlwm yog feem ntau los txiav cov kev ncig hauv nruab nrab hauv qhov kav dej lossis kho qhov ntsuas ntws ntawm qhov nruab nrab hauv cov raj xa dej. Flange npauj npaim li qub tau dav siv hauv kev tsim cov khoom lag luam dav dav xws li dej num kev txuag dej, kho dej, roj av, tshuaj ua kom dej, thiab cua sov hauv nroog. Nws kuj tseem siv tau rau ntawm cov cua txias thiab cov dej txias hauv tshuab ua cua sov.
2. Flanged npauj npaim li qub tuaj yeem muab faib ua qhov muag muag flange npauj npaim li qub thiab tawv foob flange npauj npaim li qub raws li qhov khoom siv zoo nkauj sealing. Lub sealing khub ntawm muag muag flange yam npauj npaim valve yog ua los ntawm elastic sealing khoom xws li roj hmab thiab fluoroplastic; txoj kev sib khi ntawm cov tawv ntim tawv flange hom npauj npaim valve yog ua los ntawm cov hlau-rau-hlau, hlau-on-fluorine yas thiab ntau txheej txheej pawg thawj coj. Lub nplhaib sib khi ntawm lub ntsej muag ntim muag flange hom npauj npaim valve tuaj yeem muab ntim rau hauv lub cev valve tso tawm thiab tuaj yeem ntsia ib ncig ntawm lub disc. Thaum siv los ua lub tshuab kaw hluav taws xob, nws qhov kev ua tau zoo tuaj yeem ncav cuag FCI70-2: 2006 (ASME B16 · 104) VI. Qib yog ntau dua li qhov nyuaj-ntim flange npauj npaim valve; txawm li cas los xij, cov ntaub qhwv lub ntsej muag muag flange npauj npaim feem ntau siv nyob rau hauv chav tsev kub thiab dej kho vim tias cov ntaub ntim khoom muag muag tau txwv los ntawm qhov kub ntawm kev siv.
3. Hlau nyuaj foob flange hom npauj npaim valve muaj qhov zoo ntawm cov khoom siv, tuaj yeem hloov kho kom ua haujlwm siab dua, ua haujlwm siab dua, kev pab cuam lub neej ntev dua li cov phom muag, tab sis qhov luv luv ntawm cov tawv foob flange hom npauj npaim valve kuj tseem pom tseeb, nws yog nyuaj ua tiav kev sib khi thiab kev ua haujlwm tsis zoo ntawm kev sib khi. Yog li no, xws li flanged npauj npaim li qub feem ntau yog siv rau kev kho cov dej ntws hauv qee qhov uas tau ua tiav qhov tsis txaus.
Tsis tas li ntawd, flanged npauj npaim li qub yog tsim tshwj xeeb rau kev tsim cov kab uas hla loj, uas tau siv dav hauv txoj kab uas hla loj haum kev siv. Thaum flanged npauj npaim valve qhib tag nrho, flanged npauj npaim valve tuaj yeem tswj qhov ntws ntawm qhov nruab nrab rhiab heev thaum qhib lub kaum sab xis ntawm lub disc yog li ntawm 15 txog 70 degrees.
Tsis tas li, txij li npauj npaim disk ntawm flange npauj npaim valve tau so qhov kev ua tau zoo thaum lub sij hawm tig hloov, lub valve tuaj yeem siv rau hauv cov yeeb nkab txhawm rau nres qhov nruab nrab granular, lossis tuaj yeem siv rau cov hmoov raws li lub zog sib khi. Hauv daim ntawv ntawm granules thiab granular media.
