[0016] I. This high-sealing fire extinguisher valve is equipped with a fixed ring, a sliding groove, a first spring, a limiting plate, a locking block, an insert block, and a square groove. When the button is pressed manually, the button causes the damping rod to rotate inside the damping block, which in turn causes the fixed rod to push the lower pressure block downward. The lower pressure block causes the sealing ring to slide inside the nozzle neck, causing the second spring to be pressed downward. At the same time, the insert block is inserted into the fixed ring. The buffering force of the first spring causes the locking block to push the limiting plate backward until the insert block penetrates the bottom of the fixed ring. Simultaneously, the reset effect of the first spring causes the locking block to penetrate into the square groove, thus fixing the insert block. This ensures that the sealing ring provides a sealing effect to the inside of the nozzle neck and will not rebound, thereby achieving a better sealing effect on the valve port and preventing loosening when not in use.

[0017] II. This high-sealing fire extinguisher valve is equipped with a nozzle, nozzle cover, connecting shaft, rotating ring, sliding rod, damper, locking rod, slot, and groove. When not in use, the nozzle cover can be placed on the outer surface of the nozzle, and the connecting shaft and sliding rod are inserted into the slot. When they reach the bottom, the damper's damping effect pushes the locking rod into the groove. To open, simply rotate the rotating ring, which in turn rotates the connecting shaft, causing the locking rod to press against the inner wall of the groove. This causes the damper to be squeezed back into the slot, and the valve can then be pulled out. This enhances the protection of the fire extinguisher and reduces the risk of leakage.
