Kodi pali kusiyana kotani pakati pa valavu ya butterfly ndi valavu ya butterfly ya flange?

Ma valve a butterflyndimavavu a butterflyndi mitundu iwiri yofala ya mavavu agulugufe.Mitundu yonse iwiri ya mavavu agulugufe imakhala ndi ntchito zambiri, koma abwenzi ambiri sangathe kusiyanitsa pakati pa mavavu agulugufe ndi ma valve a butterfly, ndipo sadziwa kusiyana pakati pa ziwirizi.

Chophika cha agulugufe ndi flange ndi njira ziwiri zolumikizirana.Pankhani ya mtengo, mtundu wawafer ndi wotsika mtengo, mtengo wake ndi pafupifupi 2/3 ya flange.Ngati mukufuna kusankha ma valve omwe atumizidwa kunja, gwiritsani ntchito mtundu wa wafer momwe mungathere, womwe ndi wotsika mtengo komanso wopepuka.

Ma valve amtundu wa Wafer amakhala ndi mabawuti ataliatali ndipo amafunikira kulondola kwamangidwe kwapamwamba.Ngati ma flanges a mbali zonse ziwiri sali ogwirizana, mabawutiwo amakhala ndi mphamvu yometa kwambiri, ndipo valavu imatha kutayikira.

Mavavu agulugufe amtundu wa wafer nthawi zambiri amakhala aatali.Pansi pa kutentha kwakukulu, kukula kwa bawuti kungayambitse kutayikira, kotero sikuli koyenera ma diameter akuluakulu a chitoliro pansi pa kutentha kwakukulu.Kuphatikiza apo, mavavu agulugufe wa wafer nthawi zambiri sangagwiritsidwe ntchito kumapeto kwa payipi ndi kunsi kwa mtsinje kumene ikufunika kupasuka, chifukwa pamene flange ya kunsi kwa mtsinje ikaphwanyidwa, valavu yopyapyala imagwa.Pankhaniyi, gawo lalifupi liyenera kupangidwa padera.Pofuna kusokoneza, ndipo valavu ya butterfly yamtundu wa flange ilibe mavuto omwe ali pamwambawa, koma mtengo wake udzakhala wapamwamba.

Valavu yagulugufe ya wafer ilibe ma flanges pa malekezero onse a valavu, mabowo ochepa chabe, ndipo valavu imagwirizanitsidwa ndi flanges pamapeto onse awiri ndi ma bolts / mtedza.Mosiyana ndi zimenezi, disassembly ndi yabwino kwambiri, ndipo mtengo wa valve ndi wotsika, koma choyipa chake ndi chakuti malo amodzi osindikizira ali ndi vuto, ndipo malo onse osindikizira amayenera kupasuka.

Valavu ya butterfly yamtundu wa flange ili ndi ma flanges kumapeto kwa thupi la valve, zomwe zimagwirizanitsidwa ndi chitoliro cha chitoliro, ndipo kusindikiza kumakhala kodalirika, koma mtengo wopangira ma valve ndi wokwera kwambiri.
