Mavavu agulugufe: Kusiyana pakati pa Wafer ndi Lug

Mtundu wa Wafer

+Zopepuka
+Zotsika mtengo
+Kuyika kosavuta

-Mapaipi flanges amafunikira
-Zovuta kuziyika pakati
-Osayenerera ngati valve yomaliza
Pankhani ya valavu yagulugufe wamtundu wa Wafer, thupi limakhala ndi mabowo ochepa omwe sanabowole.Mitundu ina ya Wafer ili ndi ziwiri pomwe ina ili ndi zinayi.

Mabowo a flange amalowetsedwa kudzera m'mabowo a bawuti a mapaipi awiri amitundu iwiri komanso mabowo apakati a valavu yagulugufe.Mwa kulimbitsa mawotchi a flange, zitolirozo zimakokedwa kwa wina ndi mzake ndipo valavu ya gulugufe imamangiriridwa pakati pa ma flanges ndikugwiridwa.

Mtundu wa lug

+Yoyenera ngati valve yomaliza *
+Chosavuta pakati
+Zosamva bwino pakagwa kusiyana kwakukulu kwa kutentha

-Zolemera ndi zazikulu zazikulu
-Zokwera mtengo
Pankhani ya valavu yagulugufe yamtundu wa Lug pali zomwe zimatchedwa "makutu" pamtunda wonse wa thupi momwe ulusi umalowamo.Mwa njira iyi, valavu ya gulugufe imatha kumangika pamtundu uliwonse wa mapaipi awiriwo pogwiritsa ntchito mabawuti awiri (amodzi mbali iliyonse).

Chifukwa valavu ya gulugufe imamangiriridwa ku flange iliyonse kumbali zonse ziwiri ndi mabawuti osiyana, aafupi, mwayi wopumula kudzera mukukula kwamafuta ndi wocheperako kuposa valavu ya Wafer.Zotsatira zake, mtundu wa Lug ndiwoyenera kugwiritsa ntchito zomwe zili ndi kusiyana kwakukulu kwa kutentha.

*Komabe, pamene valavu yamtundu wa Lug ikugwiritsidwa ntchito ngati valavu yotsiriza, munthu ayenera kumvetsera chifukwa ma valve ambiri agulugufe amtundu wa Lug adzakhala ndi mphamvu yotsika kwambiri yololedwa monga valavu yotsiriza kusiyana ndi momwe gulu lawo la "zachilendo" likusonyezera.
