Nres valve sab nraud tuaj yeem ua haujlwm, rau qhov flange to, lub flange bolts nruj dua, yog tias tsis yog, peb yuav tsum qhib nws kom pom tias lub flange gasket puas, rau ntim cov xau, kom nruj packing gland, yog tias cov ntim tau xoob dhau. , peb yuav tsum tau ntxiv packing, yog hais tias lub cev yog ncaj qha nyob rau hauv lub to, low-pressure lo lus yuav tsum tau welded, yog hais tias nws yog siab, cia li tso tseg, kev ruaj ntseg ua ntej, rau sab hauv to taub teeb meem, qhov teeb meem tsis zoo los txiav txim, ua ntej. , tej zaum yuav tsis raug kaw, thiab ces quab yuam tawm me ntsis, qhov thib ob, lub valve lub rooj foob kev puas tsuaj, qhov no yuav tsum tau rov sib tsoo, rau qhov kev puas tsuaj ntawm lub spool, nyob ntawm seb nws puas yog scouring puas los yog kev puas tsuaj los ntawm kev tawm tsam, tab sis ob qho tib si rau re-weld lub sealing nto.
Internal to feem ntau yog lub rooj zaum valve lossis spool sealing nto puas, qhov no tuaj yeem zom lub rooj zaum lossis lub rooj sib khi, tab sis muaj qhov xwm txheej tshwj xeeb yog tias hluav taws xob lossis pneumatic valve stroke yuav tsis raug teeb tsa kom raug. Kev tawm sab nraud yog nyob ntawm qhov chaw xau, yog tias lub valve lub cev xau tuaj yeem hloov lub valve.
Yog hais tias lub hauv paus to yuav tsum muaj teeb meem nrog lub sealing nto, lub sealing nto kom pom cov nyhuv.
