Detailed Description
The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.
The semi-automatic air tightness test device shown in fig. 1-3 comprises a pressure test pool 1, water filled in the pressure test pool 1, a plurality of first cylinders 2 located in the pressure test pool 1, and a workbench 3 connected to piston rods of the first cylinders 2. The cylinder body of the first cylinder 2 is connected in the pressure test pool 1. The pressure testing pool 1 is provided with a handle 11, so that the pressure testing pool is convenient to carry.
The device also comprises a plurality of second cylinders 6 positioned on the workbench 3 and a pressure test sealing plate 4 positioned on the workbench 3. The workbench 3 is provided with a plurality of mounting holes 30, and in this embodiment, the mounting holes 30 are threaded holes. The pressure test sealing plate 4 and the second cylinder 6 are both connected to the workbench 3 through the mounting hole 30.
The device also comprises a pressure plate 61 connected to the piston rod of the second cylinder 6 and a pressure test product 5 positioned on the pressure test sealing plate 4. The pressure test product 5 is a box-shaped casting. The opening of the pressure test product 5 faces downwards, and the pressure plate 61 presses the pressure test product 5 on the pressure test sealing plate 4, so that a closed space is formed between the pressure test product 5 and the pressure test sealing plate 4.
The pressure test sealing plate 4 comprises a rubber plate 43 and a steel plate 44 which are connected in an overlapping manner. The pressure test product 5 is pressed on the rubber plate 43, so that the connection sealing performance of the pressure test product 5 and the pressure test sealing plate 4 is improved, and the gap air leakage between the pressure test product 5 and the pressure test sealing plate 4 is prevented.
