Title:
AIR-TIGHTNESS DETECTION DEVICE FOR PIPELINE
Document Type and Number:
WIPO Patent Application WO/2020/118996
Kind Code:
A1
Abstract:
An air-tightness detection device for a pipeline, comprising: a device body (1); an air inlet disposed at the device body (1) and communicating with an external air source; an airflow output unit (2) disposed at the device body (1) and used to output an airflow; an airflow recovery unit (3) disposed at the device body (1) and used to recover an airflow; and an air pressure sensor disposed at the airflow recovery unit (3). Two ends of the pipeline are connected to the airflow output unit (2) and the airflow recovery unit (3), respectively. An air-tightness detection device for a pipeline inputs an airflow into the pipeline, detects an air pressure of an output airflow from the pipeline, and compares air pressures of the input airflow and the output airflow, thereby effectively determining whether the pipeline is leaking. The device has a simple structure and high detection efficiency, and can quickly and easily examine the air-tightness of the pipeline.
