Kusiyana Pakati pa Wafer ndi Lug Type Butterfly Valve

Vavu ya gulugufe ndi mtundu wa valavu yozungulira kotala yomwe imalamulira kuyenda kwa chinthu mu payipi.

Ma valve a gulugufenthawi zambiri amagawidwa m'magulu awiri: mtundu wa lug ndi mtundu wa wafer. Zigawo izi zamakina sizisinthasintha ndipo zili ndi ubwino ndi ntchito zosiyana. Buku lotsatirali likufotokoza kusiyana pakati pa mitundu iwiri ya ma valavu a gulugufe ndi momwe mungasankhire valavu yoyenera zosowa zanu.

Valavu ya Gulugufe ya Lug-style

Ma valve a gulugufe opangidwa ngati zingwe nthawi zambiri amapangidwa ndi chitsulo monga chitsulo chosungunuka kapena chitsulo. Amakhala ndi zingwe zolumikizidwa ndi ulusi zomwe zimayikidwa pa ma flange a ma valve kuti zilumikize ma bolt.Ma valve a gulugufe ofanana ndi Lug ndi oyenera kugwiritsidwa ntchito kumapeto kwa mzere koma flange yobisika nthawi zonse imalimbikitsidwa.

Valavu ya Gulugufe Yokhala ndi Kalembedwe Kokulumulira

Ma valve ambiri a gulugufe a mtundu wa wafer amapangidwa ndi mabowo anayi omwe amagwirizana ndi payipi yolumikizidwa. Vavu iyi idapangidwa kuti igwirizane pakati pa ma flange awiri mu ntchito yanu ya mapaipi. Ma valve ambiri a gulugufe a wafer amakwaniritsa miyezo yambiri ya flange. Mpando wa valavu wa rabara kapena EPDM umapanga chisindikizo champhamvu kwambiri pakati pa valavu ndi kulumikizana kwa flange.Mosiyana ndi ma valve a gulugufe a mtundu wa lug, ma valve a gulugufe a mtundu wa wafer sangagwiritsidwe ntchito ngati malekezero a mapaipi kapena ntchito yomaliza mzere. Mzere wonse uyenera kutsekedwa ngati mbali iliyonse ya valavu ikufunika kukonzedwa.
