Thin Walled Pressure Vessel

The invention discloses a fast and safe opening and closing device for a special pressure vessel, which mainly relates to the technical field of pressure vessels. A sealing cover is provided, a hollow rod is provided in the middle of the sealing cover, a ventilation hole is provided on the outer wall of the bottom of the hollow rod, a sealing plate is provided at the bottom end of the hollow rod, and the upper cover of the hollow rod A return spring is provided, a support sleeve is provided on the hollow rod, and several connecting rods are arranged in an array on the support sleeve, one end of the connecting rod is hinged with the support sleeve, and a locking block is hinged at the other end, and the ladder A locking groove compatible with the locking block is provided in the shaped feed port, a threaded press sleeve is provided on the top of the support sleeve, and a hand wheel is provided on the threaded press sleeve. The beneficial effects of the utility model are: safe to use, It can quickly open and close the pressure vessel and can automatically release the pressure when the pressure vessel is opened.

Therefore, determining the defect discrimination of bottle pressure vessels is an important problem in the use of containers at present. The main reason for the possible failure of pressure vessels is that the corrosion fatigue of bottle pressure vessels will produce certain microcracks on bottle pressure vessels. , and through extension, brittle fracture eventually occurs.
