2. The two mutually-backed-up electric detonators are symmetrically arranged in a Y-shaped structure, so that the centering of detonation wave acting on the cutter during detonation of the two electric detonators is improved, the problem of blocking caused by the fact that detonation wave acting force on the cutter is eccentric due to the fact that detonation is asynchronous is avoided, and meanwhile, the energy loss caused by turning and eccentricity is reduced and the redundant electric detonators are improved in actuating capacity and detonation reliability through reasonably setting a claw (Y) angle.
3. The three redundant sealing structures such as the metal thin-wall expansion ring sealing structure, the nonmetal sealing ring sealing structure and the metal conical surface wedging sealing structure ensure that high-temperature fuel gas generated during electric explosion of the electric explosion tube cannot leak to the working medium flow passage.
4. By arranging the triangular stress groove at the cutting part of the blind pipe, the force required by cutting is reduced, and the cutting reliability is improved.
