- Osayenerera ngati valve yomaliza
Pankhani ya valavu yagulugufe wamtundu wa Wafer, thupi limakhala ndi mabowo ochepa omwe sanabowole. Mitundu ina ya Wafer imakhala ndi ziwiri pomwe ina ili ndi zinayi kapena zisanu ndi zitatu.
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.
+ Yoyenera ngati valve yomaliza
+ Yosavuta kuyiyika pakati
+ Osamva bwino pakagwa kusiyana kwakukulu kwa kutentha
- Cholemera chokhala ndi zazikulu zazikulu
- Zokwera mtengo
Pankhani ya valavu yagulugufe yamtundu wa Lug pali zomwe zimatchedwa "makutu" pamtunda wonse wa thupi momwe ulusi unapangidwira. Mwa njira iyi, valavu ya butterfly imatha kumangidwa pazitsulo zonse ziwiri za mapaipi 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 ndioyenera kugwiritsa ntchito zomwe zili ndi kusiyana kwakukulu kwa kutentha.
Komabe, valavu yamtundu wa Lug ikagwiritsidwa ntchito ngati valavu yomaliza, munthu ayenera kumvetsera chifukwa ma valve agulugufe ambiri amtundu wa Lug adzakhala ndi mphamvu yotsika kwambiri yololedwa monga valavu yotsiriza kusiyana ndi momwe gulu lawo la "zachizolowezi" likusonyezera.
