Description

一种金属纤维管道阻火器
技术领域
本实用新型涉及一种管道附件,特别涉及一种金属纤维管道阻火器。
背景技术
工业和民用易燃易爆气体在管道或设备内着火,火焰会很快蔓延,引起大量气体剧烈燃烧爆炸,造成火灾。因此,通常在易燃易爆气体管道中安装阻火器,起到防止外部火焰窜入存有易燃易爆气体的设备、管道或阻止火焰在设备、管道间蔓延的作用。目前,传统的金属网及非金属阻火器等虽构造简单,但阻火性能欠佳,且密封性能不好。而较新式的波纹板式阻火器等虽然阻火性能较好,但结构复杂。
因此,为解决上述技术问题,有必要提供一种结构简单、经济适用、安全可靠的阻火器。
实用新型内容
本实用新型的目的在于提供一种结构简单、阻火性强、重复利用率高的金属纤维管道阻火器。
为实现上述目的,本实用新型采取的技术方案为:一种金属纤维管道阻火器,包括进口锥形壳体(1)和出口锥形壳体(2),所述锥形壳体(1)两端设置有法兰盘(3)和(4),内部设置有阻火芯(7),所述锥形壳体(2)两端设置有法兰盘(5)和(6),内部设置有阻火芯(8),其特征是所述进出口锥形壳体中均设置有阻火芯,具有多道阻火作用,提高了安全性。
本实用新型的金属纤维管道阻火器,所述的阻火芯(7)设置为多层金属纤维织物,且具有透气孔。
所述的阻火芯(8)设置为多层金属纤维烧结毡,且具有透气孔。
与现有技术相比,本实用新型具有如下特点和有益效果:所述的阻火芯(7)和阻火芯(8)共同工作,具有多道阻火作用,安全可靠。进出口锥形壳体两端均设置有法兰,连接方便快捷,整体结构简单。阻火芯更换方便,且材料价格低廉,资源丰富,具有良好市场推广应用前景。
附图说明
图1为本实用新型实施例的结构示意图。
具体实施方式
参照说明书附图1,将法兰盘(3)和(4)焊接在进口锥形壳体(1)两端,将法兰盘(5)和(6)焊接在出口锥形壳体(2)两端。
将阻火芯(7)置于进口锥形壳体(1)中。
将阻火芯(8)置于出口锥形壳体(2)中。
将法兰(4)和(6)采用螺栓、螺母、垫片密封连接。
