[0001] The utility model relates to the technical field of airtightness detection, in particular to an airtightness detection device for a secondary air outlet valve. Background Art

[0002] The air outlet valve is a commonly used pipeline valve. Its main function is to help the gas in the pipeline to be automatically discharged and maintain the normal operation of the pipeline. The air outlet valve can be divided into mechanical air outlet valve, hydraulic air outlet valve and automatic exhaust valve.

[0003] After the secondary air outlet valve is produced, it needs to be tested for air tightness to ensure that the secondary air outlet valve can be used normally. However, when some existing air tightness detection devices are used, the height of the gas pipe is fixed, and the height of the mounting base cannot be adjusted. When detecting secondary air outlet valves of different sizes, it is inconvenient to use. For this reason, we provide an air tightness detection device for a secondary air outlet valve to solve the above problem. Utility Model Content

[0014] III) Beneficial effects

[0015] Compared with the prior art, the airtightness detection device of the secondary air outlet valve has the following beneficial effects:

[0016] 1. The utility model cooperates with components such as a threaded rod 1 and a baffle plate. First, the threaded rod 1 can adjust the position of the limit plate, and the movement of the limit plate is controlled by rotating the threaded rod 1. The air pipe is moved by the movement of the limit plate, so that the air pipe can be connected to secondary air outlet valves of different lengths.

[0035] Working principle: When using the device, firstly, it is necessary to rotate the threaded rod 11 according to the length of the secondary air outlet valve. The rotation of the threaded rod 11 will cause the transmission block 12 to move with the mounting seat 13. After the mounting seat 13 moves to the appropriate position, the staff pushes the push rod 14. The push rod 14 will separate the baffle 6 from the tooth plate 5.
