Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1-4, the electric fire damper comprises a valve frame 1 and at least one pair of valve plates 2 arranged in the valve frame 1, wherein a sealing assembly is arranged between the adjacent valve plates 2 and between the valve plates 2 and the valve frame 1, and the sealing assembly comprises a spring mechanism and an air bag mechanism 14 made of fire-proof materials; the spring plate mechanism is arranged on the valve plate 2 and closes the adjacent valve plate 2 and a gap between the valve plate 2 and the valve frame 1 when the valve plate 2 is closed; the air bag mechanism 14 is arranged between the valve plate 2 and the elastic sheet mechanism, and when the elastic sheet mechanism is deformed under pressure, the air bag mechanism 14 inflates and expands. When a fire disaster happens, the fire prevention valve is closed, the adjacent valve plates 2 and the valve frame 1 are firstly sealed through the elastic sheet mechanisms, the valve plates 2 extrude the elastic sheet mechanisms when the elastic sheet mechanisms are sealed, and then the air bag mechanisms 14 start to inflate, because the valve plates 2 are sealed at the moment, the sealing pressure between the adjacent valve plates 2 and the valve frame 1 is only increased when the air bags inflate, the sealing performance of the fire prevention valve is enhanced, and because the air bag mechanisms 14 are made of fire prevention materials, the air leakage can still be realized even if the fire prevention valve is influenced by high temperature, the sealing pressure is ensured, the leakage of smoke and fire from the gaps of the valve plates 2 is prevented, and the sealing performance of the fire prevention valve is enhanced.
The spring plate mechanism comprises a first spring plate 11 and a second spring plate 12, the first spring plate 11 is attached to the edge of the valve plate 2, the second spring plate 12 is fixed on the first spring plate 11 and extends outwards, and an acute angle is formed between the second spring plate 12 and the first spring plate 11. Seal through first shell fragment 11 and second shell fragment 12 between the adjacent valve plate 2, when sealed, second shell fragment 12 is extruded by valve plate 2 and is out of shape, with the laminating of first shell fragment 11, and gasbag mechanism 14 is arranged in between first shell fragment 11 and second shell fragment 12, is extruded and is out of shape along with second shell fragment 12, indirectly extrudes gasbag mechanism 14, triggers gasbag mechanism 14 and aerifys, increases sealing pressure, prevents the firework and leaks, and sealed effect is better.
The spring plate mechanism comprises a third spring plate 13, the third spring plate 13 is L-shaped, one end of the third spring plate 13 is arranged on the valve frame 1, and the other end of the third spring plate 13 is attached to the valve plate 2 when the valve plate 2 is closed. The air bag mechanism 14 is arranged between the third elastic sheet 13 and the valve frame 1, and the air bag mechanism 14 is arranged below the valve plate 2 when the valve plate 2 is closed. The third shell fragment 13 is adopted in the sealed between valve plate 2 and the valve frame 1, and along with valve plate 2 extrusion third shell fragment 13, third shell fragment 13 extrudes gasbag mechanism 14, triggers gasbag mechanism 14 and aerifys the tympanites, increases the leakproofness here, prevents that fireworks from here leaking, and sealed effect is better.
The airbag mechanism 14 includes a body in which a medicament bag is disposed, and when the body is squeezed, the medicament bag is broken to generate gas to inflate the body. The medicament bag can be separated for the sump that is used for the water storage and the medicine storehouse that is used for placing the calcium oxide that do not communicate with each other in the medicament bag, and when the body received the extrusion, the medicament bag was broken, and the water in the sump and the calcium oxide in the medicine storehouse mix and react, release a large amount of gas, and gas is tied in this internal for the body is bloated, thereby strengthens here sealing performance, avoids fireworks to leak, and sealing performance is better.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
