Abstract

所述的带螺旋翼的塑料落水管的主要特征是管壁圆周上设有沿轴向方向设置的通透的孔管,将这种带螺旋翼的塑料落水管对接安装并将每根孔管的两端封堵,这种孔管就成为很好的隔音体,因此,本实用新型既能减少落水对管壁的压力,又能大大降低落水噪音。

Description

带螺旋翼的塑料落水管
本实用新型涉及一种带螺旋翼的塑料落水管。
水在落水管中因落差会对落水管壁产生很大的水锤压力,塑料落水管往往承受不了这种压力,于是出现了带螺旋翼的塑料落水管,使水在落水管内沿螺旋翼旋转下落,从而减少了水对落水管的压力,但是由此产生的并通过管壁传出的水流噪音却增大了,影响了环境质量。
本实用新型的目的是提供一种能降低噪音的带螺旋翼的塑料落水管。
本实用新型的解决方案是管壁圆周上设有沿轴向方向设置的通透的孔管。
将上述结构的塑料落水管对接安装并将每根孔管的两端封堵后,这种孔管就成为很好的隔音体,因此,这种带螺旋翼的塑料落水管能大大降低落水噪音。
下面结合附图和实施例来阐明本实用新型的具体内容。
图1:本实用新型的俯视图;
图2:本实用新型的A-A剖视图。
如图所示,本实用新型所述的带螺旋翼的塑料落水管,管壁1的内侧设有螺旋翼2,管壁1圆周上设有沿轴向方向设置的通透的孔管3。该孔管3在管壁1中通常采取均布的方式来设计,螺旋翼2从管壁1上伸出,并呈螺旋状,翼宽要小于落水管的内径,本实施例采用六条螺旋翼2,均布在管壁1上。
