Air tightness detection device for sterile aluminum barrel

The utility model relates to a sterile aluminum barrel air tightness detection device which comprises a detection cabinet body and a vacuum pump, a sterile aluminum barrel can be placed in the detection cabinet body, and the vacuum pump is communicated with the detection cabinet body through an exhaust pipe. A vacuum meter is mounted at the top end of the detection cabinet body; when an air tightness test is carried out, the sterile aluminum barrel is placed in the detection cabinet body, and the vacuum pump vacuumizes the interior of the detection cabinet body; when the vacuum degree reaches the standard, vacuumizing is stopped immediately, the vacuum environment in the detection cabinet body is kept for a certain time, and a worker can observe the air pressure change in the detection cabinet body through a vacuum meter and judge the air tightness of the sterile aluminum barrel; after the detection is completed, the blowoff valve is opened, the air pressure in the detection cabinet body is balanced with the
