Redundant ignition control device of multistage perforation

The utility model relates to a redundant ignition control device of multistage perforation draws two circuits at the rifle head of the dark instrument lower extreme in school, a line connection votage control switch, and a line connection electricity selects the switch. Every votage control switch has connect the diode, and every votage control switch is established ties until connecing bridging plug point firearm, and every electricity selects the switch to establish ties, and the top has connect resistance, every votage control switch selects the switch to connect an electric cap with every electricity, and the electric cap is through this grade of votage control switch of dipolar pipe connector. The utility model discloses there is voltage -controlled on -off control in every perforation rifle, has the electricity to select on -off control or two electric caps of diode control. In the first order perforation rifle, votage control switch percussion electric cap, or another electric cap of diode circuit percussion. In second, the tertiary perforation rifle, votage control switch percussion electric cap, or with another electric cap of electronic switch percussion. The utility model discloses simultaneously with voltage -controlled formula and the electronic type technique of igniteing many times, ignition convenient operation, improvement perforating operation reliability is suitable for the shale air to open to adopt perforating operation.
