Abstract

The invention discloses an air inflation mechanism which comprises a valve body, a valve rod, a valve rod and a valve rod. The valve element is slidably located in the mounting channel in the axis direction of the valve body, an inflation channel penetrating through the valve element is formed in the valve element, and the far end of the valve element is exposed out of the valve body; the hoop is operably hooped outside the far end of the valve core and the far end of the valve body; the sealing piece is arranged outside the far end of the valve element in a sleeving mode, and the sealing piece is operably abutted against the end face of the far end of the valve body and the valve element in the axis direction of the valve body; the valve body is provided with a gas injection channel, a part of the valve element is communicated with the gas injection channel, and the part, communicated with the gas injection channel, of the valve element is located on the side, close to the near end of the valve element, of the gas injection channel. The sealing device has the beneficial technical effects of convenience in operation, cost reduction and reliable sealing performance.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of sealing, and in particular to an inflation mechanism. Background technique [0002] In the prior art, for the helium-filled vacuum helium test at the nozzle of the container, the airtightness of the nozzle is tested. In order to realize the detection of the nozzle, the diameter of the nozzle of the container to be detected needs to be sealed for filling. [0003] The existing detection method is water detection, which is to weld the nozzle of the container, soak it in water as a whole, observe whether there are bubbles, and then cut it off after the detection is completed. This detection method is greatly disturbed by human beings, and the leakage rate cannot be quantified. , and the sealing device of the water test cannot be used on the helium test device, and its processing is relatively difficult and the cost is high. Therefore, particularly need a kind of new sealing mode, ...
