Pipeline noise reduction structure convenient to install

The utility model discloses a pipeline noise reduction structure convenient to install, and belongs to the technical field of water supply and drainage. Comprising a sewer pipe body, the special pipe joints are sleeved at two ends of the sewer pipe body; and the drainage assembly is used for reducing sewage noise and is clamped and mounted between the two special pipe joints. Vacuum noise reduction protection can be formed on the outer portion of the sewer pipe body through the hollow pipe body, the mute effect of drainage of the sewer pipe body is improved under the dual noise reduction protection of the sound insulation cotton, the hollow pipe body of the semi-circular-ring-shaped structure can be conveniently installed on the outer portion of the sewer pipe body, and therefore the installation efficiency is improved. 本申请公开了一种安装便捷的管道降噪结构，属于给排水技术领域。包括下水管体；特制管接头，套接安装于下水管体两端；用于降低污水噪音的引流组件，卡接安装于两特制管接头之间。利用中空管体可对下水管体外部形成真空降噪防护，并在隔音棉的双重降噪防护下，提高下水管体排水的静音效果，且呈半圆环型结构的中空管体便于安装在下水管体外部，从而提高安装效率。
