Abstract

本发明公开了一种防火自动卷帘门，包括防火隔烟雾卷帘门，所述的防火隔烟雾卷帘门装于限位滚筒上，限位滚筒与启动限位滚筒的热敏启动器连接，热敏启动器上安装有控制热敏启动器的热敏头，所述的热敏启动器包括阀体、设于阀体下部的滚筒限位头，滚筒限位头上套有蓄能弹簧，阀体内设有保压油腔，阀体的上部安装有热敏头。本发明自动有效地在楼梯的门口处阻止火势和隔断火势的漫延。

Description

防火卷帘门
技术领域
本发明涉及一种消防装置，具体地说是一种防火卷帘门。
背景技术
当大楼发生火灾时，火势常通过楼梯门上窜下延，因此，如何有效地在楼梯的各楼层之间设置防火门，以阻止火势和隔断火势的漫延显得十分要紧，但在目前还没有一种阻止火势的自动防火门。
发明内容
本发明的目的是设计出一种自动防火卷帘门。
本发明要解决的是大楼发生火灾时，在楼梯的门口处阻止火势和隔断火势漫延的问题。
本发明的技术方案是：本发明包括卷帘，所述的卷帘装于限位滚筒上，限位滚筒上设有热敏启动器连接；所述的热敏启动器包括阀体、设于阀体内的滚筒限位头，滚筒限位头上套有蓄能弹簧，滚筒限位头顶部伸出于阀体且插于限位滚筒的限位孔内，，阀体内设有保压油腔，阀体的上部设有热敏头滚筒限位头。
本发明的优点是：自动有效地在楼梯的门口处阻止火势和隔断火势的漫延。
附图说明
图1是本发明的结构示意图。
图2是本发明热敏启动器的结构示意图。
图3是本发明热敏头的结构示意图。
具体实施方式
下面结合附图及实施例对本发明作进一步说明。
如图所示，本发明包括卷帘1，所述的卷帘1装于限位滚筒4上，限位滚筒上设有热敏启动器3连接；所述的热敏启动器3包括阀体、设于阀体内的滚筒限位头6，滚筒限位头上套有蓄能弹簧7，滚筒限位头6顶部伸出于阀体且插于限位滚筒4的限位孔2内，阀体内设有保压油腔8，阀体的上部设有热敏头9。
所述的卷帘下端装有配重横杠。
所述的热敏头9包括油管10、设于油管10内的密封钢珠11、封于油管10端部的热敏材料石蜡13和设于油管外壁的感温金属鳍片-薄铜鳍片12。
本发明的防火原理是：当火势到达楼梯门时，热量及火烟使高温使热敏材料石蜡13熔化，密封钢珠11因蓄能弹簧7的弹力被上推，滚筒限位头6上移，且从限位滚筒4上退出，这时卷帘1因配重横杠的重力作用，自动落下。
