The invention provides a rocket blow-off centralized gas supply system. The rocket blow-off centralized gas supply system comprises a gas source, a pressure reducer, a manual switch, a normally-open type electromagnetic valve, a ground throttling orifice plate, a rocket-ground pipeline connector and a plurality of on-rocket throttling orifice plates. An air source outlet is connected with an inlet of the pressure reducer, an outlet of the pressure reducer is connected with an inlet of the normally-open electromagnetic valve through the manual switch, an outlet of the normally-open electromagnetic valve is connected with the ground throttling orifice plate, the ground throttling orifice plate is connected with the rocket-ground pipeline connector, and the rocket-ground pipeline connector is connected with the multiple on-rocket throttling orifice plates. By means of centralized gas supply and graded throttling, on one hand, the number of pipelines which are originally connected to the ground can be reduced, and on the other hand, a ground gas supply system can be simplified.

    本发明提供了一种火箭吹除集中供气系统,包括:气源,减压器,手动开关,常通式电磁阀,地面节流孔板,箭地管路接头,若干箭上节流孔板;气源出口与减压器进口连接,减压器出口通过手动开关与常通式电磁阀(进口连接,常通式电磁阀出口与地面节流孔板连接,地面节流孔板再与箭地管路接头连接,箭地管路接头分别与若干箭上节流孔板连接。本发明通过集中供气,分级节流的方式,一方面可以减少原本箭地连接的管路数量,另一方面可以简化地面供气系统。
