The terms "vertical," "horizontal," "left," "right," and the like as used herein are for descriptive purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, the present invention provides a pressure relief explosion-proof valve 100, wherein the pressure relief explosion-proof valve 100 includes a water inlet valve seat 10, a water outlet valve seat 20 and a sealing member. One end of the water inlet valve seat 10 is groove-shaped, and the water inlet valve seat 10 is provided with a water inlet 110. The outlet valve seat 20 is disposed opposite to the inlet valve seat 10, one end of the outlet valve seat 20 facing the inlet valve seat 10 is recessed, and the outlet valve seat 20 is provided with a water outlet 210. The outlet valve seat 20 is connected to the inlet valve seat 10 to form a receiving cavity 220, and the receiving cavity 220 is communicated with the inlet 110 and the outlet 210, so that when neither the inlet 110 nor the outlet 210 is sealed, external water can enter the receiving cavity 220 from the inlet 110 and then flow out from the outlet 210.

Referring to fig. 3, the sealing member is disposed in the accommodating cavity 220. The sealing member includes a first magnet 310 and a second magnet 320, and the sealing member includes a first magnet 310 and a second magnet 320. The first magnet 310 is movably disposed, and the first magnet 310 is disposed corresponding to the water inlet 110. When the first magnet 310 is attached to the water inlet 110, the water inlet 110 is blocked. When the first magnet 310 is not attached to the water inlet 110, the water inlet 110 is in an open state, and external water can enter the receiving cavity 220 from the water inlet 110.

When the external water pressure is greater than the repulsive force between the first magnet 310 and the second magnet 320, the external water pushes the first magnet 310 toward the second magnet 320 to open the water inlet 110 for pressure relief, thereby preventing the valve from being exploded due to the external water pressure exceeding a threshold value. When the external water pressure is reduced to be less than the repulsive force between the first and

second magnets

310 and 320, the first magnet 310 is fitted to the water inlet 110 by the repulsive force to block the water inlet 110 again.
