一种具有方形旋转轴的防火阀结构
本技术涉及消防设备
,具体涉及一种具有方形旋转轴的防火阀结构。
技术介绍
防火阀通常安装在排烟、通风管道上,用于在发生火灾时封闭管道,防止火势沿风道蔓延。目前,使用的防火阀结构通常是包括有框体及若干防火叶片,若干防火叶片通过圆形轴旋转安装在框体内,叶片与圆形轴之间通过焊接或用夹紧片固定在一起,一方面不仅不环保,另外一方面叶片相对圆形柱容易打滑。
技术实现思路
鉴于以上内容,有必要提供一种具有方形旋转轴的防火阀结构。为达到上述目的,本技术所采用的技术方案是:一种具有方形旋转轴的防火阀结构,所述防火阀结构包括有框体、弹性件、旋转轴、叶片、固定件及垫片,所述框体包括有顶框、底框及两侧框,所述顶框及所述底框相互平行,所述两侧框相互平行,并且分别与所述顶框及所述底框连接,所述顶框对应旋转轴开设有旋转孔;所述底框内侧安装有定位框,所述定位框包括有定位板及两限位边,所述两限位边分别设在所述定位板的相对两侧,并安装在所述底框上,所述定位板与所述顶框平行,并对齐旋转孔开设有沉孔,所述沉孔的底部开设有贯穿定位板的转动孔,所述沉孔的内径大于转动 ...
