摘要:
A temperature-activated valve for a conventional fire sprinkler utilizing a hyperelastic single-crystal shape memory alloy is described. The shape-memory element expands as it is heated, forcing a bolt to break, thereby opening the sprinkler valve. The devices described are less susceptible to accidental breakage than conventional actuators, and have fewer moving parts. Transition temperature of the shape memory alloy can be tuned to a narrow range.
摘要(中):
描述了使用超弹性单晶形状记忆合金的常规消防喷淋器的温度启动阀。 形状记忆元件在被加热时膨胀,迫使螺栓断裂,从而打开喷洒阀。 所描述的装置比常规致动器更不容易意外断裂,并且具有较少的移动部件。 形状记忆合金的转变温度可以调整到较窄的范围。
