U gawo valavu butterfly, it ndi mtundu wa valavu yagulugufe yokhazikika, yomwe imatchedwanso "concentric", "rabala yokhala ndi mphira" ndi "rabala yokhala pansi" ya gulugufe, ili ndi mpando wa rabara (kapena wokhazikika) pakati pa kunja kwa disc ndi khoma lamkati la valavu.

Kuyenda kwa diski kudzatsimikizira malo a butterfly valve.Mtundu wokhazikika wokhala pansi pa butterfly valve wafer ukhoza kugwira ntchito ngati valavu yodzipatula ngati diski imazungulira kutembenuka kwathunthu kwa madigiri 90, valavu imatsegulidwa kwathunthu kapena kutsekedwa.

Valavu ya butterfly ndi valavu yotembenukira kotala yomwe imazungulira madigiri 90 kuti mutsegule kapena kutseka kutulutsa kwa media.Lili ndi diski yozungulira, yomwe imadziwikanso kuti butterfly, yomwe imapezeka pakatikati pa thupi lomwe limagwira ntchito ngati njira yotseka valve.Chimbalecho chimalumikizidwa ndi actuator kapena chogwirira kudzera mu shaft, yomwe imadutsa kuchokera ku diski kupita pamwamba pa thupi la valve.

Valavu ya butterfly imagwiritsidwanso ntchito ngati valavu yowongolera kuthamanga, ngati diskiyo sizungulira mpaka kotala lonse, zikutanthauza kuti valavu yatseguka pang'ono, titha kuwongolera kutuluka kwamadzi mwa kutsegula kosiyanasiyana.ngodya.

(Tchati ya CV/KV ya valavu yagulugufe yokhazikika yokhala pansi ikupezeka mukapempha)

Kachiwiri, malinga ndi njira yokhazikitsira,U gawo la butterfly valve,ilinso valavu yamtundu wa wafer.

ma flanges amapangidwa kuti agwirizane ndi kuyika kwa mavavu akulu akulu akulu, chifukwa mu kampani yathu, mavavu agulugufe okhazikika okhala ndi mtundu wamtundu wamtundu wamtundu wamtundu wa DN32 mpaka DN600. valavu gulugufe, umene ndi mndandanda wina wa mankhwala.

mutha kupeza kusiyana pakuyika kwa mtundu wa wafer wa butterfly wokhala pansi, mtundu wa U ndi mtundu wa flange iwiri.
