The invention discloses a fireproof door without fire endurance. The fireproof door without the fire endurance comprises a door frame and a water filling fireproof door installed in the door frame, and further comprises a water inlet tube and an automatic inlet valve; the water filling fireproof door is internally provided with a cavity for filling the water; the upper and lower ends of one side of the water filling fireproof door are respectively provided with an upper door spindle and a lower door spindle; the door frame is correspondingly provided with a shaft sleeve matched with the upper and lower door spindles; the water filling fireproof door is sleeved in the door frame by the upper and lower door spindles and can be rotated around the door frame; the upper door spindle is provided with a through hole communicating with the cavity in the water filling fireproof door; the water inlet tube is connected with a fire hose and one end is protruded into the through hole of the upper door spindle; and the automatic inlet valve is installed at the water outlet end of the water inlet tube. The fireproof door without the fire endurance is capable of effectively reducing the rate of the temperature increase of the fireproof door, improving the reliability of the fireproof door, and breaking through the limit of the fire endurance of the traditional fireproof door, and the fireproof door always has the fireproof smokeproof functions only if the water in the fireproof door does not dry up.
