Vacuum cabin for helium detection of high-pressure hydrogen storage pressure vessel

The invention discloses a vacuum chamber for helium detection of a high-pressure hydrogen storage pressure vessel, which comprises a vacuum chamber main body, an anti-explosion release valve, a pump interface, a helium leakage detection interface, a vacuum chamber door and a detection assembly, and is characterized in that a stainless steel pipe is added between double-layer seamless stainless steel pipes, and the stainless steel pipe is filled with an anti-explosion buffer net made of steel wires, so that the weight of the vacuum chamber is reduced to a great extent; the design and manufacturing cost is saved, the strength of the vacuum chamber is greatly improved, through tests, the design structure meets the explosive power of 2.5 Kg equivalent TNT, the structure of the vacuum chamber is intact, the chamber door is normally opened and closed, and the tank body is not deformed. The explosive power is greater than the explosive power requirement of 2.09 Kg equivalent TNT in the design requirement; and the sa
