Pipeline buffering device

The utility model relates to the technical field of emptying pipelines, in particular to a pipeline buffering device. The pipeline buffering device comprises a device shell with a buffering cavity, an air inlet and an air outlet are formed in the top and the bottom of the device shell respectively, a baffle extending in the transverse direction is arranged on the inner wall of the buffering cavity, and a filter screen is arranged on an air circulation path between the air inlet and the air outlet. The buffer device is simple in structure, can be mounted in pipelines such as an emptying pipeline or a pressure guide pipe and the like, and is used for reducing the flow speed of airflow and relieving pressure, so that potential safety hazards caused by the fact that impurities in the pipelines are splashed out along with the airflow during emptying are avoided. 本实用新型涉及放空管线技术领域，特别涉及一种管路缓冲装置。本实用新型的一种管路缓冲装置，包括具有缓冲腔的装置外壳，所述装置外壳的顶部和底部分别设置有进气口和出气口，所述缓冲腔的内壁上设置有沿横向延伸的挡板，所述进气口与所述出气口之间的气体流通路径上设置有滤网。本实用新型的缓冲装置，结构简单，可安装在放空管线
