Inverted arch slotted rupture disk with shear failure

The utility model provides an inverted arch slotted rupture disk with shear failure, which has a double-layer structure and comprises a sealing film, a plurality of elastic pieces, a plurality of elastic pieces, a plurality of elastic pieces and a plurality of elastic pieces. The supporting frame is located above the sealing film, planar sealing fixing edges are arranged on the periphery of the supporting frame, the supporting frame is tightly attached to the sealing film fixing edges, and the supporting frame is further provided with a supporting piece located in the center of the supportingframe and used for bearing one-way compression force; the supporting bridges are located on the edges of the supporting pieces and protrude outwards from the edges of the supporting pieces, and the circumferential widths B of the supporting bridges are larger than the radial lengths L of the supporting bridges; the connecting part is used for connecting the supporting bridge with the fixed edge; the breaking elements are
