Description

阻火器
技术领域
本发明涉及一种阻火器，特别是在符合防护等级Ex-d的防爆壳体中用作减压主体的阻火器。
背景技术
出版物DE 10 2014 116 149 A1公开了一种阻火器，该阻火器包括大量的金属丝织物层，这些金属丝织物层显示不同的网眼宽度和金属丝厚度，并且优选地还显示不同的取向。由于交替的网眼宽度和各个层相对于彼此的角度偏移，形成迷宫状通道，这一方面防止了火焰传播，并且另一方面具有良好的透气性特征。各个层例如通过烧结彼此连接。然而，已经发现，在由于爆炸而在壳体中可以产生脉冲压力负载的情况下，这种阻火器在中心承受比在外围区域中更剧烈的流。
发明内容
本发明的目的是设计一种具有改进的流动能力的阻火器。
这个目的通过根据权利要求1所述的阻火器来实现：
根据本发明的阻火器包括多个金属丝织物层，所述金属丝织物层具有不超过极限dmax的网眼宽度。在任何情况下，金属丝织物层的数量都多于两层；优选地，存在限定迷宫状孔的五层或更多层。根据本发明的阻火器包括由多个金属丝织物层形成的至少两个这样的部件主体，在这两个部件主体之间布置有中间层，该中间层具有大于两个部件主体的限定网眼宽度范围内的最大网眼宽度的网眼宽度。布置在两个部件主体之间的中间层形成压力分布层，该压力分布层允许相对于主流动方向横向的流动，例如径向取向的流动，并且因此导致中间层内的压力均衡。特别地，压力均衡会导致减压主体在承受脉冲压力负载时的表面利用率提高，并因此导致其流动阻力降低。因此，压力峰值比以前得到更有效地降低。
由于两个部件主体与中间层的牢固连接 ，另外获得了特别坚固的减压主体，该减压主体可具有大的表面。
金属丝织物层优选地包括直径在特定金属丝直径范围D内的金属丝，两个部件主体的金属丝织物层的任何金属丝都不超过该金属丝直径范围D的上限dmax。然而，中间层优选地具有直径为dz的金属丝，该直径大于金属丝直径范围D内的最大直径dmax。优选地，其附加地或替代地适用于如下情况：中间层的网眼宽度mz是网眼宽度范围M内的最大网眼宽度mmax的至少1.5倍。上述两种措施中的每一者都导致中间层中横向流动的阻力更低，并且因此导致中间层中良好的压力均衡。因此，由压力波产生的流动在中间层中变宽，使得与没有中间层的情况相比，在更大的表面上使用流动方向R下游的部件主体。
中间层可被构造为织物以及交叉金属丝的网格并且由等效结构形成。形成横向流动的可能性至关重要。
附图说明
本发明有利实施例的附加细节是从属权利要求、相关描述和附图的主题。它们在其中示出：
图1是根据本发明的阻火器的示意性横截面显示，
图2是根据图1的阻火器的横截面的细节，
图3和图4是示出根据图1和图2的阻火器中的网眼宽度和金属丝直径的示意图，
图5是根据图1的阻火器的细节的分解透视图，
图6是根据图1至5的阻火器的金属丝织物层的单独分解透视图，以及
图7是当压力波冲击时，根据图1的阻火器在壳体壁中的示意性横截面显示。
具体实施方式
图1示出了减压主体10的示意性示意图，减压主体10可以附接在防爆壳体的壳体壁中或壳体壁上，以便允许壳体内部空间和环境之间的快速压力均衡。减压主体10包括形成第一部件主体12的第一数量的金属丝织物层11。提供了附加数量的金属丝织物层13，附加数量的金属丝织物层13以材料结合的方式彼此连接并形成第二部件主体14。分别在两个部件主体12、14中彼此连接的金属丝织物层优选地通过在它们的边缘上焊接、特别地通过烧结来连接，使得存在分别分布在金属丝织物层11和13的表面上的大量连接点。
在两个多孔部件主体12、14之间布置有中间层15，中间层15优选地被构造为金属丝织物层，并且其进一步优选地连接到两个部件主体12、14，优选地以材料结合的方式连接到两个部件主体，例如通过烧结。在这种情况下，部件主体12、14与中间层15形成单个烧结主体。此外，减压主体10可在其垂直于流动方向R的两个平坦表面上设置有金属丝织物层16、17，金属丝织物层16、17例如包括与中间层15匹配的金属丝织物，或者其具有与中间层15承受相同条件的网眼宽度和金属丝直径。
图2示出了包括中间层15、部件主体12和覆盖层16的放大细节II。如图2以稍微夸张的方式所示，在这情况下，中间层15的金属丝18的直径dz明显大于部件主体12中的任何金属丝直径（图4）。在任何情况下，部件主体12包含多于两个、优选地多个金属丝织物层11，金属丝织物层11优选地占据部件主体12的整个横截面的整个表面。根据图4，存在于金属丝织物层11中的金属丝19的直径在范围为从最小直径dmin到最大直径dmax的金属丝直径范围D内。金属丝直径下限dmin为近似0.1毫米，而上限dmax优选至多为1毫米。中间层15的金属丝18的金属丝直径dz固定在该直径范围D之外。优选地，中间层15的金属丝18的直径dz是直径范围D的最大直径dmax的至少1.5倍。这类似地适用于覆盖层16的金属丝20。
中间层15中的各根金属丝的金属丝直径可变化。然而，适用的是，至少限定两个部件主体12、14之间的距离的金属丝（诸如，例如，金属丝18）具有在直径范围D之外的直径dz。
就部件主体12和中间层15中的网眼宽度m方面，条件是相似的。背衬织物层11中的网眼宽度m——在部件主体12中——在范围为从最小网眼宽度mmin到最大网眼宽度mmmax的网眼宽度范围m内。最小网眼宽度mmin在十分之一毫米的范围内，而最大网眼宽度mmax在一毫米的范围内。中间层的网眼宽度mz大于出现在部件主体12中的最大网眼宽度mmax，优选地是其至少1.5倍。
优选地，类似的条件适用于部件主体14。然而，在这情况下，金属丝织物层11的数量可不同于部件主体12、14中的金属丝织物层13的数量。
图5以分解图示出了减压主体10的结构的细节。明显的是，中间层15的两个平坦表面由部件主体12和14的金属丝织物层11和13邻接。如从图2中已经明显的是，这些可制成不同的金属丝厚度，并且另外可具有不同的取向。除了不同的金属丝厚度之外，部件主体12和14的各个层中的每一层至少优选地具有不同的网眼宽度m。尽管部件主体12、14的各个层具有在网眼宽度范围M内的不同的网眼宽度m，但是中间层15的网眼宽度mz在该网眼宽度范围M之外。
图6示出了部件主体12的三层11的优选地不均匀的角度取向。在每一层中，金属丝织物包括彼此平行的经金属丝和彼此平行并与经金属丝交叉的多个纬金属丝。尽管不同的形式也是可能的，但是本示例性实施例中的部件主体12是圆形的，使得各个层11代表相对于中心轴线21的圆盘。各个层围绕中心轴线21相对于彼此旋转角度β，使得例如叠加层11的纬金属丝分别围绕该角度β相对于彼此旋转。因此，在每个接触平面中产生分布在表面上的不同图案的接触点，在这些接触点处，各个层通过烧结工艺彼此材料结合。一层的金属丝覆盖其他层的网眼，使得形成具有多角度的而不是笔直的通孔的多孔主体。
图7示出了减压主体10在壳体的内部空间22发生爆炸的情况下的功能。在壳体壁23中布置有减压主体10，以实现源自内部空间22进入到环境中的快速压力均衡。
图7示出了壳体壁23附近的这种爆炸24，在这种情况下，作为球形压缩冲击传播的压力波25由处于不同时间处的圆弧描绘。在较早的时间t0处，压力波25撞击在减压主体10上。因此，热气体穿过部件主体12并在时间t1处撞击在中间层15上。在这一点处，首次可能产生大体积横向流，其结果是压力冲击——如箭头26、27所指示的——相对于中心轴线21径向向外扩散。因此，扩散的压力波沿着宽的前部穿过第二部件主体14，如图7通过代表压力波的圆弧t2的较小曲率所示。作为其结果，减压主体在扩大的表面上穿过。在中心区域中流动不那么集中，并且整个流动阻力减小。
根据本发明的阻火器10包括两个部件主体12、14，这两个部件主体12、14包括不同的金属丝织物层11、13并且通过具有特别粗网眼的金属丝织物的中间层15彼此连接。粗网眼的金属丝织物优选地包括粗金属丝。该中间层15的金属丝直径和网眼宽度都优选地远大于用于部件主体12、14的金属丝的网眼宽度和金属丝直径。
根据本发明的减压主体10结合了高度的机械稳定性与大阻火能力，并且同时具有非常低的流动阻力。
