Example 1
As shown in fig. 1 and 4, this embodiment provides a gas cylinder 1 with a sealing structure, the gas cylinder 1 includes a cylinder body, a bottleneck and a bottleneck, and further includes a sealing base 2 and a sealing ring 3, the sealing base 2 is sleeved on the outer surface of the bottleneck, the sealing base 2 is in sealing connection with the bottleneck, the sealing ring 3 is sleeved on the outer surface of the sealing base 2, and a radial seal is arranged between the sealing ring 3 and the sealing base 2.
In this embodiment, the gas bottle 1 is filled with high-pressure gas, and the bottle mouth is sealed by a membrane 4. When in use, the bottle neck of the gas bottle 1 is inserted into the cavity 51 of the wine taking device 5, and the membrane 4 on the bottle neck is broken through the pricking pin 52 in the cavity 51, so that the gas pressure in the gas bottle 1 is communicated with the space in the cavity 51. Meanwhile, the inner wall of the cavity 51 radially extrudes the sealing ring 3 on the gas cylinder 1, so that an interference fit tight fit relation is formed between the sealing ring 3 and the side wall of the sealing base 2 and between the sealing base and the side wall of the cavity 51, and the sealing base 2 is in sealing connection with the bottle neck, so that the sealing effect between the gas cylinder 1 and the wine taker 5 can be realized.
In the embodiment, the sealing junction element is arranged on the gas cylinder 1, so that one bottle is thrown one time, and the service life requirement on the sealing element is reduced. The additionally arranged sealing element can ensure the assembly precision of the sealing position of the gas cylinder 1 and the sealing performance of the gas cylinder 1 under high pressure.
Further, the outer surface of the bottle neck is provided with an external thread 11, the inner surface of the sealing base 2 is provided with an internal thread 21, and the internal thread 21 is matched with the external thread 11. The root of the thread of the high-pressure gas cylinder 1 with external threads 11 is provided with a sealing base 2, and the sealing base 2 is used for fixing a sealing ring 3 so that a sealing element is connected with the gas cylinder 1 into a whole. Considering that the integral process of the integral molding of the sealing base 2 and the gas cylinder 1 is complex, the sealing base 2 and the gas cylinder 1 are manufactured separately, the gas cylinder is molded by stretching and extrusion, and the sealing base 2 and the bottleneck of the gas cylinder 1 are fixed by screwing through threads, so that the processing process is simplified, and the assembly process of the sealing base 2 and the gas cylinder 1 is simple and convenient. Meanwhile, the external thread 11 of the bottle neck of the gas bottle 1, which is positioned above the sealing base 2 (near the bottle mouth), can also be used for the threaded connection of the inner wall of the cavity 51 of the wine taking device 5.
