Abstract: An explosion-proof valve includes a valve body that includes a connection section at an edge of the valve body and a scored groove, and an opening region on a radial inner side of the connection section. A shape of an orthographic projection of the valve body and a shape of an orthographic projection of the opening region in a depth direction of the scored groove are non-circular. An outer edge of the orthographic projection of the opening region is an opening boundary. An area of the orthographic projection of the opening region is Sopen, an area of an orthographic projection of the connection section is g Sconnect, and an area of the orthographic projection of the valve body is Stotal, where Sopen, Sconnect, and Stotal meeting: 10%

Abstract: An explosion-proof valve comprises an explosion-proof valve body. which is provided with score grooves, and the score grooves comprise two first score grooves, two second score grooves, and one third score groove. One end of each of the two first score grooves and one end of each of the two second score grooves are respectively connected to two ends of the third score groove. The other ends of the two first score grooves extend in a direction away from each other, and the other ends of the second score grooves extend in a direction away from each other. The explosion-proof valve body comprises an opening area. In the depth direction of the score grooves, the outer edge of the orthographic projection of the opening area is a predetermined opening boundary, and the area of the orthographic projection of the opening area is (I), wherein S≥80 mm2, c≥4 mm, and α≥30°.
