An online dry powder bag leak detection device includes: an adjustable clamp, a spacing positioning component, a pressure gauge, a pressure tube, and a pressure tapping tube. The adjustable clamp includes first and second pressure plates arranged in parallel, connected by an adjustable connector, and the spacing between the two pressure plates is adjustable. A slot is provided on the first pressure plate. The online dry powder bag is placed between the two pressure plates, with the online connector located in the slot and protruding upwards from the first pressure plate. The spacing positioning component includes a positioning body and spacing positioning platforms of different thicknesses disposed on the positioning body. The spacing positioning platforms can be inserted between the first and second pressure plates to position the spacing between them. One end of the pressure tube is connected to an external air source, and the other end is connected to the liquid inlet pipe of the online connector. One end of the pressure tapping tube is connected to the liquid outlet pipe of the online connector, and the other end is connected to a pressure sensor. This invention improves the accuracy and ease of operation for leak detection of online dry powder bags with welded online connectors.
