[0001] The utility model relates to the technical field of protection devices, in particular to an automatic protection device for a pressure gauge under ultra-high pressure. Background Art

[0002] The ultra-high pressure automatic protection device for pressure gauges is a safety device used to protect equipment from damage caused by excessive pressure. This device usually starts automatically when the pressure exceeds the set safety threshold to prevent equipment damage or accidents. It does not require human intervention and can start automatically under ultra-high pressure conditions, greatly reducing manual operation errors and delays.

When the pressure in the container is too high, the pressure is relieved through the pressure inside the pressure relief pipe 3 to avoid excessive pressure and accidents. When the pressure relief pipe 3 discharges air pressure, the air pressure will push the sealing block 9 to move. When the sealing block 9 moves, it will drive the cylinder 12 to move synchronously, and then the cylinder 12 will drive the conductive sheet 13 to move. When the sealing block 9 moves out of the pressure relief pipe 3, the pressure relief pipe 3 is no longer sealed. The conductive sheet 13 moves and contacts with the conductive ring 11, and then the current inside the battery assembly 15 will flow into the inside of the buzzer 16, so that the buzzer 16 works and emits a sound warning, thereby achieving the purpose of warning the staff, which is convenient for the staff to deal with the container with too high pressure and avoid accidents.

When the pressure in the container is too high, the pressure inside the pressure relief pipe 3 is relieved to avoid excessive pressure and accidents. When the pressure is discharged from the pressure relief pipe 3, when the pressure is relieved, when the pressure inside the overpressure protector 1 is too high, a guide frame 7 is fixedly installed inside the pressure relief pipe 3, and the guide frame 7 passes through the interior of the sliding plate 6, and a pressure spring 8 is installed around the guide frame 7, and one end of the pressure spring 8 is fixedly connected to the outer wall of the sliding plate 6 to push the closing block 5 to move.
