航天科技海鹰集团有限公司推出了一种无源自动喷水灭火系统。该灭火系统采用温度传感器驱动磁耦合组件来启闭喷淋阀,而无需电源和任何外动力。灭火后还能感应温度降低而自动关闭,而且可以反复使用。由于它可以实现“跨步式”灭火,对水压的要求也不高,能够自动关闭,从而有效地避免了水浸造成的二次灾害,这都是传统自动喷水灭火系统所无法相比的。该系统拥有9项专利技术(双稳态双控流量控制阀、
Aerospace Science and Technology Group Co., Ltd. launched a passive Sprinkler automatic sprinkler system. The fire suppression system uses a temperature sensor to drive the magnetic coupling assembly to open and close the spray valve without power and any external power. After the fire can also sense the temperature decreases and automatically shut down, and can be used repeatedly. Because it can achieve “stepping” fire extinguishing, the water pressure is not high, can automatically shut down, so as to effectively avoid the secondary flooding caused by disasters, which are traditional sprinkler system can not Compared to The system has nine patented technologies (bistable dual control flow control valve,
