Explosion-proof ignition gun suitable for high-pressure environment

The invention discloses an explosion-proof type ignition gun suitable for a high-pressure environment. The explosion-proof type ignition gun comprises an electric lead-in device, a sealing assembly and an ignition gun body. The sealing assembly is installed between the electrical lead-in device and the ignition gun body, and the ignition gun body is installed on the spaceflight furnace in a sealed mode. According to the invention, explosion suppression is realized through the electrical introduction device; the sealing assembly can tolerate the high pressure of 10 MPa, high-pressure gas in the furnace is prevented from leaking out, and high-pressure-resistant reliable sealing is achieved. 本发明公开了一种适用于高压环境的隔爆型点火枪，包括：电气引入装置、密封组件及点火枪本体；密封组件安装在电气引入装置和点火枪本体之间，点火枪本体密封安装在航天炉上；本发明通过电气引入装置实现了隔爆；通过密封组件可以耐受10MPa高压，阻止了炉内高压气体外泄，实现了耐高压可靠密封。
