Tank sealing performance detection tool

A tank sealing performance detection tool comprises an air tightness detector, the air tightness detector is connected with a pressing plate through a connecting air pipe, an air inlet of the connecting air pipe is provided with an air inlet sealing gasket, and the pressing plate is further provided with a nozzle boss sealing gasket; the pressing plate is driven to move by the downward-pressing push cylinder and is in sliding fit with the guide rod, and one end of the guide rod is connected with the tank clamp. According to the tool, the sealing performance of the tank body can be measured by adopting two detection modes at the same time, and the detection reliability is greatly improved; the tool can realize on-line multiple pressing tests, can meet the requirements of various working conditions, and is helpful for improving the test accuracy. 一种罐体密封性检测工装，包括气密性检测仪，气密性检测仪通过连接气管与压板连接，连接气管的进气口设有进气口密封垫，压板上还设有喷口凸台密封垫；压板由下压推缸驱动移动，压板与导杆滑动配合，导杆一端与罐体夹具连接。本工装能够同时采用两种检测方式对罐体进行密封性测量，检测的可靠性大大提高；本工装可以实现在线多次打压测试，能够满足多种工况需要
