Description
technical field [0001] The invention relates to the technical field of airtightness detection, in particular to a quick detection device for the airtightness of an ignition seat of a gas generator. Background technique [0002] The igniter is an important part in the gas generator. When the car collides, the igniter plays an ignition role, and the igniter is installed in the igniter seat. In the actual assembly, first weld the igniter seat on the upper shell of the gas generator, then put the sealing ring into the igniter seat, and finally put the igniter into the igniter and connect it by pressure riveting, in order to ensure the stability of the gas generator The sealing performance of the gas generator is very high. If the connection between the igniter and the igniter seat is not well sealed, the gas generator will be scrapped. Therefore, it must be sealed after the igniter and the igniter seat are connected. However, at present, the tightness detection of the ignition ...
