U gawo valavu butterfly, it ndi mtundu wa valavu yagulugufe yokhazikika, yomwe imatchedwanso "concentric", "rabala yokhala ndi mphira" ndi "mphira wokhala" agulugufe valavu, 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 wa butterfly valve wafer ukhoza kugwira ntchito ngati valavu yodzipatula ngati diski ikuzungulira 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.

Valve ya butterfly imagwiritsidwanso ntchito ngati valavu yowongolera kutuluka, 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 valavu butterfly,ilinso ndi valve yamtundu wa wafer.

ma flanges amapangidwa kuti agwirizane ndi kuyika kwa mavavu akulu akulu akulu, chifukwa kampani yathu, mavavu agulugufe okhala pansi ndi mtundu wa lug ndi a 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.
