摘要
井下风门在通风负压的作用下能够自动关闭,对于负压大的地点,风门关闭迅速,力量大,容易挤伤通行人员。新型风门采用压缩空气为动力,能够实现自动控制,有效地减轻了劳动强度;两道风门自动闭锁,能够防止通风系统风流短路;在实际应用中取得了良好的经济及安全效益。
Air door in mines could close automatically under negative pressure ventilation. But at the position with large negative pressure, the air door closes rapidly and strongly so as to cause injury of passing persons. Powered by compressed air, new air door could be controlled automatically in order to reduce the labor intensity. Automatic closing of two air doors could effectively prevent the short circuit of air flow in the ventilation system, which has achieved good economic and safe benefits in applications.
