The technical scheme for realizing the purpose of the invention comprises the following steps: the utility model provides a pressure vessel's safety uncap pressure release device which characterized in that: the pressure-relieving type pressure-relieving device comprises a rotatable handle (3), a button (4), a hook (5) and a spring (6) which are arranged on a cover body, wherein the cover body comprises an upper cover (1) and a lower cover (2), the handle (3) comprises a driving part (30) at the upper part, a pushing part (31) of a sealing ring (7) of which the lower part is ejected out of a pressure container, and a connecting part (32) penetrating through the upper cover (1) and the lower cover (2), when the driving part (30) of the handle is in a working position, the pushing part (31) is in non-contact fit with the sealing ring (7), when the driving part (30) of the handle is rotated to a pressure-relieving position, the pushing part (31) ejects out of the sealing ring (7) to relieve pressure, the button (4) is arranged on the upper cover (1) and is positioned right below the driving part (30) of the handle in the working position, the hook (5) comprises a rotating shaft (50) pivoted at the middle part on the lower cover (2), a buckling position (9) of which the lower end is arranged on a casing (8) of the pressure container, a locking part (51) can be in a clutched mode, and a locking part (51) of the locking part is in contact with the upper end (4) of the casing (8) of the pressure container is arranged on the upper cover (2), one end is in a pressing position of the hook (52) is in contact with the upper part (52), and the other end is in contact with the hook (5) is in the position, and the other end is in the position is in contact with the upper part (52) of the pressure-relieving part (5), the lock tongue (51) of the hook (5) is contacted and locked with the buckling position (9) when the button (4) is not pressed.

Two protruding limit buckles (41) are arranged at the bottoms of the two sides of the button (4).

The lower cover (2) is provided with a pair of lugs (21) with mounting holes, and a through hole (22) for the bolt (51) of the hook (5) to pass through is formed in the lower cover (2) between the two lugs (21).

The sealing ring (7) is positioned between the upper cover (1) and the lower cover (2), and the upper cover (1) and the lower cover (2) are fixed through screws or buckles.

The invention has the beneficial effects that: because the button for uncovering is positioned under the driving part of the rotatable handle when the driving part is positioned at the working position, the button is covered, and therefore, when the pot cover is to be opened, the driving part of the handle is required to be rotated to the pressure release position to press, thereby realizing the purpose of safely uncovering.
