The figure is a side sectional view showing an embodiment of the present invention,
1 is a weather cover, 2 is a fire damper, 3 is a spring, 4 is a shape memory alloy, 5 is a metal with good thermal conductivity, 6 is a lower opening, and 7 is a ventilation hole.
Claims (1)
内部に、火災の場合下部開口部６を閉じる目的の
防火ダンパー２を、スプリング３を有する一端を
可動する様に固定し、その防火ダンパー２を常温
でかぎ状の形状記憶合金４にて引き上げて開放状
態となし、万一火災でウエザーカバー１の内部の
温度上昇時に熱伝導率の良い金属５がまず熱せら
れ、形状記憶合金４が高温時に記憶した棒状とな
り、止め金がはずれて防火ダンパー２はスプリン
グ３の力が反動となり、自動的に落下して下部開
口部６を閉じるようになしたる、形状記憶合金を
使用せる防火ダンパーを有するウエザーカバー。 Inside the weather cover 1 attached to the ventilation hole 7, a fire damper 2 for the purpose of closing the lower opening 6 in the event of a fire is fixed so that one end having a spring 3 is movable, and the fire damper 2 is kept at room temperature. It is pulled up using a hook-shaped shape memory alloy 4 to open it, and in the event of a fire and the temperature inside the weather cover 1 rises, the metal 5 with good thermal conductivity will be heated first, and the shape memory alloy 4 will memorize the temperature at high temperatures. A weather cover having a fire prevention damper using a shape memory alloy, which becomes a rod shape, and when the clasp is released, the fire prevention damper 2 is reacted by the force of the spring 3 and automatically falls to close the lower opening 6. .
