[0027] Reference Figures 1 to 4 A lightweight gas storage device includes a gas cylinder liner 1, a fiber resin 2, an air inlet 3, a drainage part 4, and an end sleeve 5. The gas cylinder liner 1 is formed by an injection molding machine mold, and the fiber resin 2 is wrapped around the outside of the gas cylinder liner 1. The fiber resin 2 has a thickness of 1.5 mm to 3 mm. After the wrapping is completed, the robot is put into a heating furnace for heating and curing. The air inlet 3 and the drainage part 4 are respectively arranged at both ends of the gas cylinder liner 1.

[0028] The air intake portion 3 includes an end sleeve 5 and an air intake end 31. The end sleeve 5 is connected to the air storage cylinder inner liner 1 by a trapezoidal thread. The air intake end 31 is threadedly connected to the end sleeve 5. A sealing ring groove 6 is provided on the side of the air intake end 31. A sealing ring 7 with a diameter of 53 mm and / or 55 mm is provided in the sealing ring groove 6. The air intake end 31 is provided with three threaded holes 8 for air intake connection.

[0029] The drainage part 4 includes an end sleeve 5, a drainage end 41, a drainage valve 42, and a drainage pipe 43.
