I-valve ye-butterfly ye-ventilation kagesi isetshenziswa ngokukhethekile kuzo zonke izinhlobo zomoya, okuhlanganisa igesi yothuli, ukushisa okuphezulu kwegesi ye-flue namanye amapayipi, njengokulawula ukugeleza kwegesi noma ukucisha, kanye nezinto ezahlukene ezikhethiwe ukuhlangabezana nezinga lokushisa eliphakathi eliphansi, eliphakathi nendawo. kanye nemithombo yezindaba ephezulu, negqwalayo.Ngokuvamile, izinga lokushisa liphakathi kuka-20 ~ 425 ℃, futhi ingcindezi ingaphansi kuka-0.6MPa.Inezinzuzo zetorque encane yokusebenza nokusebenza okulula, Impilo ende yesevisi.

Ivalvu kagesi elawula umoya wovemvane ingasebenza ngokufaka isignali yokulawula (4 ~ 20mADC noma 1 ~ 5VDC) kanye nokuphakelwa kwamandla okufanelekile ukuze kuhlangatshezwane nezidingo zokusebenza kwamapayipi.I-valve ye-butterfly ye-ventilation yamukela isakhiwo esisha se-central line type disc plate kanye nesakhiwo esifushane se-steel plate welding, esinezici zesakhiwo esihlangene, isisindo esilula, ukufakwa okulula, ukumelana nokugeleza okuncane, umthamo omkhulu wokugeleza nokusebenza okulula.Isetshenziswa kabanzi ezintweni zokwakha, i-metallurgy, imoto, amandla kagesi, umoya omncane, ubunjiniyela bokuvikela imvelo nezinye izimboni.
