Split type mechanical exploder and explosion valve cartridge case driving device

Abstract

The invention provides a split type mechanical exploder and an explosion valve cartridge case driving device. The split type mechanical exploder comprises an impact exploder and a body; the body is used for being installed on a to-be-exploded cartridge case driving device, an auxiliary gunpowder chamber and a gas chamber are arranged in the body, and the auxiliary gunpowder chamber communicates with the gas chamber and a main gunpowder chamber of the to-be-exploded cartridge case driving device; the impact exploder is separably arranged on the body, the impact exploder comprises a firing pin assembly and a firing pin seat, and in a safety state, a preset safety distance is formed between a firing pin on the firing pin assembly and a needling fire cap on the firing pin seat; and in the exploding state, the firing pin on the firing pin assembly makes contact with the needle fire cap on the firing pin seat to explode the needle fire cap, so that closed gas in the gas chamber is pushed to move towards the auxiliary gunpowder chamber, and gunpowder in the auxiliary gunpowder chamber is ignited. Under the working condition that a remote current inrush exploder cannot be started for some reason, a worker carries the split type mechanical exploder to an explosion valve, the gunpowder is mechanically exploded through manual operation, the reliability is very high, and the safety is improved.

Description

technical field [0001] The disclosure belongs to the technical field of detonating devices, and in particular relates to a split mechanical detonator and a cartridge driving device for a blasting valve. Background technique [0002] The blasting valve introduced by the pressurized water reactor AP1000 is designed to use remote current to trigger the insensitive electric detonator, and then detonate the gunpowder in the cartridge, so as to achieve the blasting effect and open the blasting valve. However, in this design, if there is a breakpoint in the circuit, the circuit is broken, the lead wire of the electric detonator is in poor contact and the extreme accident situation, there is a possibility that it cannot be blasted. Contents of the invention [0003] The present disclosure aims to solve at least one of the technical problems existing in the prior art, and provides a split mechanical detonator and blasting valve cartridge driving device. [0004] In one aspect of t...
