Beschreibung
Zusammenfassung:	The utility model discloses a pressure relief manhole with seal structure floats, including valve body, guide rail and balancing disk subassembly, the balancing disk subassembly is provided with the guide rail groove including the balancing disk, adjusting plate, diaphragm and the stationary blade that loop through the coaxial fixed connection of connecting bolt in the valve body, and the guide rail is adorned in the stationary blade bottom admittedly to be connected with guide rail groove block, circumference is provided with the cyclic annular groove of floating in the adjusting plate, and the adjusting plate border is provided with contra -vane. Compared with the prior art, adopting the diaphragm structure of floating seal, having improved the sealing performance of emergency vent valve, the maintenance and maintaining be convenient for has simultaneously reduced the work load that the maintenance was maintained. The size in the unsteady groove through setting up the adjusting plate can further improve the
