npauj npaim valve flange yam Description
Lub sealing qauv ntawm lub flange npauj npaim valve siv PTFE, hluavtaws roj hmab, thiab phenolic resin los ua ib lub rooj sib xyaw, muab lub rooj zaum nrog ob qho tib si elasticity thiab txhim khu lub zog. Tsis tas li ntawd, tus npauj npaim phaj yog tag nrho coated nrog PTFE, muab nws muaj zog corrosion kuj.

Kev faib tawm ntawm Flanged Npauj Npaim Valves
Flanged npauj npaim li qub tuaj yeem muab faib ua mos-flanged npauj npaim li qub thiab tawv-flanged npauj npaim li qub raws li cov khoom siv sealing nto.
- Lub sealing sab ntawm lub mos-flanged npauj npaim valve siv elastic sealing cov ntaub ntawv xws li roj hmab thiab fluoroplastics. Nyob rau hauv sib piv, lub sealing sab ntawm lub hard-seal flanged npauj npaim valve siv cov ntaub ntawv xws li hlau-rau-hlau, hlau-rau-fluoroplastic, thiab multi-layer composite daim hlau.
Lub nplhaib sib khi ntawm lub ntsej muag muag flanged npauj npaim valve tuaj yeem muab tso rau hauv lub valve lub cev channel los yog nyob ib ncig ntawm lub periphery ntawm npauj npaim phaj. Thaum siv los ua lub kaw lus kaw, nws qhov kev sib khi tuaj yeem ncav cuag FCI70-2: 2006 (ASMEB16-104) qib VI, uas yog siab dua li ntawm lub zog foob flanged npauj npaim valve. Txawm li cas los xij, vim tias qhov ntsuas kub ntawm cov ntaub ntawv mos sealing, mos-flanged npauj npaim li qub feem ntau yog siv hauv kev txuag dej thiab kev kho dej hauv chav tsev kub.
- Hlau hard-seal flanged npauj npaim li qub muaj qhov zoo ntawm cov khoom siv ruaj khov, tuaj yeem tiv taus qhov kub thiab txias, ua haujlwm siab dua, thiab muaj kev pab cuam lub neej ntev dua li qhov muag muag. Txawm li cas los xij, qhov tsis zoo ntawm qhov nyuaj-seal flanged npauj npaim li qub kuj tseem pom tseeb heev-lawv nyuaj ua kom tiav sealing, thiab lawv cov sealing kev ua tau zoo kuj tsis zoo. Yog li ntawd, hom flanged npauj npaim valve no feem ntau yog siv rau hauv cov ntawv thov uas tsis tas yuav muaj kev sib khi ua haujlwm siab, feem ntau rau kev tswj cov dej ntws.
