[0028] According to the gas storage bottle of the first embodiment of the utility model, Figures 1 - 3 As shown, the gas cylinder may include: a gas cylinder body 1, a cylinder valve 2 and a cylinder valve protection device 3, the cylinder valve 2 is installed on the gas cylinder body 1, the cylinder valve protection device 3 is fixed to the gas cylinder body 1, and the cylinder valve protection device 3 has a protection part 31, the protection part 31 is located on the side of the cylinder valve 2 away from the gas cylinder body 1, and the protection part 31 is spaced apart from the cylinder valve 2.

[0029] It should be noted that in the related art, both ends of the existing gas cylinders are equipped with protective covers, which can protect the gas cylinder body, but the existing protective covers cannot protect the cylinder valves of the gas cylinders. The cylinder valves may still be damaged in drop tests and vehicle collisions. Damage to the cylinder valves may cause gas leakage in the gas cylinders, especially hydrogen cylinders. Hydrogen leakage may easily lead to explosion risks.

[0030] Based on this, the embodiment of the present application proposes a gas cylinder, wherein the cylinder valve 2 is mounted on the gas cylinder body 1, the cylinder valve 2 can be fixedly arranged on the side of the gas cylinder body 1, the cylinder valve protection device 3 is fixedly arranged on the gas cylinder body 1, and the cylinder valve protection device 3 can be fixedly connected to the gas cylinder body 1 by means of clamping, bolt connection, etc. The cylinder valve protection device 3 can protect the cylinder valve 2, and the cylinder valve protection device 3 has a protection part 31, and the protection part 31 is located on the side of the cylinder valve 2 away from the gas cylinder body 1. When the gas cylinder is subjected to a drop test or a vehicle collides, the protection part 31 is hit before the cylinder valve 2, and the protection part 31 can prevent the cylinder valve 2 from being directly hit. The protection part 31 is spaced apart from the cylinder valve 2, so that the protection part 31 can not affect the cylinder valve 2 after being hit, thereby achieving the effect that the cylinder valve 2 is not damaged and continues to work normally after the gas cylinder is hit. In addition, the protection part 31 is spaced apart from the cylinder valve 2, so that the cylinder valve 2 can work normally. By providing the bottle valve protection device 3, the bottle valve 2 can be protected, the probability of damage to the bottle valve 2 in a drop test and a vehicle collision can be reduced, and the risk of gas leakage caused by damage to the bottle valve 2 can be reduced, which is beneficial to improving the safety when using the gas cylinder.

[0031] In some embodiments of the present invention, Figure 3 As shown, along the arrangement direction of the bottle valve 2 and the protection part 31, the orthographic projection of the bottle valve 2 is located within the orthographic projection range of the protection part 31. The cross-sectional area of the protection part 31 can be larger than the cross-sectional area of the bottle valve 2. Along the arrangement direction of the bottle valve 2 and the protection part 31, the projection of the bottle valve 2 is completely covered by the projection of the protection part 31, so that the overall structure of the bottle valve 2 is within the protection range of the protection part 31, which is conducive to improving the protection effect of the protection part 31 on the bottle valve 2.
