Beschreibung
Zusammenfassung:	The fireproof excess pressure valve comprises a valve frame, a valve plate, a connecting rod, a heavy hammer, a torsion spring and a temperature fuse, a rotating shaft is arranged at the position, close to a front air opening of the valve frame, of the valve frame, the valve plate is connected with the rotating shaft, and the valve plate rotates with the rotating shaft as the rotating center to adjust the opening degree of the front air opening; the connecting rod is fixed to the valve plate, and the heavy hammer is arranged on the connecting rod in a sliding mode to adjust the gravity center of the valve plate, so that the pressure difference needed when the valve plate is opened is adjusted. The valve frame is provided with a limiting column, the temperature fuse is fixed in the valve frame, the rotating shaft is sleeved with the torsion spring, a first pin of the torsion spring is connected with the temperature fuse, and a second pin of the torsion spring abuts against the limiting column, so that the tors
