Description

Technical Field

[0001] The utility model belongs to the technical field of air tightness detection of storage tanks, and in particular relates to an air tightness detection device for storage tanks. Background Art

[0002] During the construction of storage tanks, the dome top of the storage tank often needs to be welded with a reinforcement plate. After the reinforcement plate is welded, it is necessary to ensure that the reinforcement plate and the tank dome plate are well sealed. The traditional method for testing the sealing of storage tanks is to weld a pipe head on the reinforcement plate and use a gas cylinder, a pipe and a pressure gauge for testing. The pipe and the pipe head, the pressure gauge and the pipe head are connected, and air is directly filled into the gap between the storage tank and the reinforcement plate through the gas cylinder. After a certain pressure is filled, stop the inflation and observe the state of the pressure gauge to judge the sealing condition between the reinforcement plate and the tank dome plate.

[0003] During use, traditional detection devices are prone to pipe entanglement and are inconvenient to store. The pressure gauge is usually placed directly on the ground, which is inconvenient to support and view. The surface is easily worn, and the top of the storage tank is usually uneven in an arc state, making it inconvenient to place the equipment.

[0004] Therefore, it is urgent to design a storage tank air tightness detection device to solve the problem of air tightness detection between the storage tank dome plate and the reinforcement plate mentioned above. Utility Model Content
