AI Technical Summary
The existing cylinder airtightness testing process is cumbersome and has low accuracy, making it difficult to efficiently test the airtightness of the tank connection.
Design an automatic cylinder airtightness testing device. The device achieves sealing by using a sealing sleeve, a connecting rod, and a T-block through the cooperation of the lower and upper closing sleeves. It combines an air inlet pipe and a detector to detect the gas content. The device is equipped with a telescopic rod and a linkage rod to adjust the height of the bearing rod, thus achieving automated testing.
It improves the intuitiveness and accuracy of detection, simplifies the operation process, and increases detection efficiency.
