DETAILED DESCRIPTION

[0015] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0016] In one embodiment, referring to the attached Figures 1-4 drawings of the specification, the utility model discloses a mine hole sealer blasting valve, which comprises a valve body 1, connection pipes 13 are installed at both ends of the valve body 1, a pressure relief hole 11 is arranged on the valve body 1, a blasting assembly 2 is installed in the pressure relief hole 11, the blasting assembly 2 is used for blasting and releasing the pressure in the connection pipe 13; a plug-in assembly 3 is arranged on the valve body 1, and the plug-in assembly 3 is used for fixing the end of the connection pipe 13 on the valve body 1.

[0017] The pressure relief hole 11 allows for timely pressure relief when a sealing device is needed. Pressure relief is achieved through the bursting component 2, which is quick and easy to remove from the pressure relief hole 11 and install. The plug-in component 3 facilitates rapid connection between the connecting pipe 13 and the valve body 1, simplifying valve installation. The valve body 1 is injection molded from engineering material in a single process. This burst valve is unaffected by hot or cold environmental conditions. Once the burst pressure value is set, the bursting component 2 will not affect its performance in different harsh operating areas, ensuring normal operation within the set pressure range.

[0018] The blasting assembly 2 includes a foil 23 disposed inside the pressure relief hole 11. The foil 23 is preferably made of an alloy material. When the foil 23 breaks, it releases the pressure inside the connecting pipe 13. A retaining ring 22 is disposed above the foil 23. The retaining ring 22 is preferably made of a metal material. A plug 21 is disposed above the retaining ring 22. A sealing ring 24 is disposed below the foil 23. The sealing ring 24 is preferably made of silicone material. Tightening the plug 21 presses the foil 23 inside the pressure relief hole 11.

[0019] The plug 21 has external threads on its outer surface and a through internal hexagonal structure inside, making it easy to turn the plug 21 with a hex wrench. The pressure relief hole 11 has internal threads inside. When the plug 21 is turned, the bottom of the plug 21 presses against the retaining ring 22, the retaining ring 22 presses against the foil 23, and the bottom of the foil 23 is fitted with a sealing ring 24. When the plug 21 is tightened, the sealing ring 24 seals the foil 23 and the pressure relief hole 11. When pressure relief is required from the pressure relief hole 11, the internal pressure of the valve body 1 increases, and the pressure is pressed under the foil 23 until the pressure breaks the foil 23. The pressure is discharged from the pressure relief hole 11 to the inside of the valve body 1 to achieve the effect of pressure relief.
