Beschreibung
Zusammenfassung:	The flue valve comprises a valve body, two parallel rotating shafts are symmetrically arranged in the valve body, one end of each rotating shaft is rotationally connected with the valve body, the other end of each rotating shaft extends out of the valve body, two semi-circular valve plates are further arranged in the valve body, and the two semi-circular valve plates are fixedly connected with thetwo rotating shafts respectively. The two semi-circular valve plates rotate along with the corresponding rotating shaft to be spliced into a circular plate, a sealing ring is arranged on the inner wall of the valve body and matched with the circular plate formed by splicing the semi-circular valve plates to seal the valve body, a driving mechanism driving the two semi-circular valve plates to rotate is arranged on the outer side of the valve body, and a pressing mechanism is further arranged on the valve body. The pressing mechanism is used for fixing the position of the semicircular valve plates when the two semicir
