当前防火排烟或防烟阀的敏感元件已开始登上新台阶,采用高科技成果的记忆合金,它替代了传统的低熔点合金,具有灵敏度高、可连续使用、性能稳定和可靠性强等特点,这种防火阀是新一代消防产品,在国内尚属首创。记忆合金元件公称动作温度可控制在±1℃以内,并可以任意调选起步温度点,额定温度动作时间仅需2秒钟。记忆合金具有形状记忆效应,随着温度的变化产生形状变化,而形 Sensitive components of current smoke exhaust or smoke-proof valves have begun to climb to new heights using high-tech memory alloys that replace traditional low-melting-point alloys with high sensitivity, continuous use, stable performance and reliability Features, this fire damper is a new generation of fire protection products, is still the first in China. Memory alloy components nominal operating temperature can be controlled within ± 1 ℃, and can choose the starting temperature point, the rated temperature action time of only 2 seconds. Memory alloy shape memory effect, with the temperature changes have a shape change, and shape
