The invention provides a sliding type fuel gas interlocking device which comprises two gas inlet connectors, a shell, a gas outlet connector, a sliding block, a spring bolt and a spring, and the shell is provided with a connecting part connected with the gas inlet connectors, the gas outlet connector and a screw cap, a sliding channel allowing the sliding block to move and a gas outlet channel; the two air inlet connectors are connected with the two ends of the shell to provide an air inlet channel. The air outlet connector is connected with the shell and provides an air outlet channel. The sliding block is provided with two limiting grooves and installed in the shell. One end of the spring bolt is connected with one end of the spring, the other end of the spring bolt is pressed on the sliding block, when the sliding block slides along the sliding channel under the action of gas, the spring bolt is matched with any limiting groove formed in the sliding block to achieve locking, and the gas outlet channel of the gas outlet connector is communicated with the gas outlet channel of the gas outlet connector. Fuel gas can be output only after fuel gas is input to the two sides through the sliding channel, fuel gas linkage of a cover throwing system and an ejection starting system is achieved, and the problems that a mechanical locking type structure is complex and poor in maintainability are solved.

    本发明提供了一种滑动式燃气连锁装置,包括两个进气接头、壳体、出气接头、滑块、锁舌和弹簧,壳体设置有与进气接头、出气接头、螺盖的连接部及供滑块移动的滑动通道和出气通道;两个进气接头与壳体的两端连接,提供进气通道;出气接头与壳体连接,提供出气通道;滑块设置有两个限位槽,安装在壳体的内部;锁舌一端与弹簧的一端连接,另一端压在滑块上,当滑块在燃气的作用下沿滑动通道滑动使锁舌与设置在滑块上的任一限位槽配合实现锁定,让出燃气出气通道与出气接头出气通道贯通。该发明通过滑动通道实现两侧均有燃气输入后,才能将燃气输出,实现了抛盖系统与弹射启动系统的燃气连锁,解决机械锁定式的结构复杂,维护性差的问题。
