KG5009风筒风量开关

KG5009风筒风量开关产品介绍

KG5009风筒风量开关是矿井风筒通风安全监测的新型装置，为本质安全型设备。KG5009风筒风量开关主要用于煤矿井下关于帆布或橡胶等柔性材质风筒 的安全监测。它安装在出风口处的风筒上，进行风筒工作状态的遥测，防爆型式为矿用隔爆兼本安型，防爆标志：Exd[ib]I。

KG5009风筒风量开关工作环境

温度：0~40℃；

相对湿度：≤98%；

大气压力：85~110KPa；

有沼气及煤尘爆炸危险环境。

KG5009风筒风量开关工作原理

KG5009风筒风量开关主要由一个LA10-1S型转换开关和两个彼此可张合的弓形夹组成。使用时，将它悬挂在风筒上方的吊环上，使弓形夹上面夹住风筒。当风筒内风量充足时，风筒内的风压使得弓形夹保持张开状态，弓形夹上的控制螺栓压下转换开关的按钮，使得转换开关的常闭触点断开，当风筒内的风压下降时，两个弓形夹会因自身的重量而合拢，此时控制螺栓便松开转换开关的按钮，其常闭触点闭合，将转换开关的这一常闭触点信号引线与FDZB-1型风电甲烷闭锁装置连接，便可进行风筒工作状态的遥测，并实现以下功能：当风筒中无风或风量低于预定值时，巷道总开关断电并闭锁。
