产品简介:

    KFM系列抗冲击自动复位式风井防爆门采用了中开式门体结构、同步开闭技术、立井上升缓冲、扭簧与风井负压联合复位等关键技术,可有效解决现有矿山风井防爆门抗冲击能力差、易变形破坏、不能自动复位等问题。目前,该产品已在陕煤化集团、晋煤集团、潞安集团、山西煤运销集团、华晋焦煤集团等企业推广应用。
   主要功能
   1.正常通风时:防爆门隔离井下气流和地面大气,密闭效果好,漏风率低;
   2.停风、检修时:防爆门能自动打开,实现自然通风,恢复供风时自动关闭;
   3.发生瓦斯、煤尘爆炸时:防爆门被气流冲击打开,起到泄压和保护风机作用;
   4.爆炸过后:防爆门能自动复位、保证通风系统恢复正常;
   5.反风时:能实现自动锁紧和远程控制,反风时间不超过5分钟。
