该防火、排烟阀是由中国建筑西北设计院研制的,它结构简单、工作灵活、动作可靠,是较理想的防火设备。本阀主要利用火灾时空气温度必然升高和产生大量烟气的特点,通过易熔合金元件和烟气感受器发出信号,并经执行机构及时将阀门关闭(或开启),同时还能给出信号,指挥相应的通风机自动切断电源而关闭(或启动),从而达到自动防
The fire prevention and smoke exhaust valve was developed by the Northwest Building Design Institute of China Construction. It is a simple structure, flexible in operation and reliable in operation. It is an ideal fire protection equipment. This valve mainly uses the characteristics that the air temperature in the fire will inevitably increase and generate a large amount of smoke. It sends signals through the fusible alloy element and the smoke sensor, and the valve is closed (or opened) by the actuator and signals can be given at the same time. , Direct the corresponding ventilator to automatically shut off the power and turn off (or start) to achieve automatic protection
