Abstract
The utility model discloses a pressure relief device of a gas film building. The pressure relief device comprises a balance box mounted on the gas film building, wherein the bottom face of the balance box is provided with a pressure relief opening communicated with the inner part of a gas film; the side face of the balance box is provided with a through hole communicated with the outside; and an air-tight balance plate is rotatably mounted on the pressure relief opening and is asymmetrically arranged relative to a rotary supporting point in a manner that one side of the balance plate is heavier. The air-tight balance plate generates a downward moment under the effect of gravity, and the downward moment is large enough to close the pressure relief opening when inner pressure of the gas film is stabilized at a pre-set value; an upward moment is generated when the pressure in the gas film acts on the bottom face of the air-tight balance plate; and when the pressure in the gas film exceeds the pre-set value, the upward moment acting on the air-tight balance plate is more than the downward moment, and the air-tight balance plate is opened. According to the pressure relief device of the gas film building, the air-tight balance plate can be used for automatically relieving the pressure when an automatic gas pressure control device cannot work normally, thereby preventing damages to the gas film building caused by sealing overpressure gas inside the gas film.
