Constant volume burner initial condition control system

Constant volume burner initial condition control system belongs to the engine technology field, the acetylene gas pitcher is connected with solenoid valve I through pressure control valve I in the system, 50% oxygen + 50% nitrogen gas jar is connected with solenoid valve II through pressure control valve II, compressed air tank is connected with solenoid valve III through pressure control valve III, three solenoid valve exit end all the way through ball valve II with preblend gas piston chamber and be connected, three another way of solenoid valve exit end is connected through ball valve I and vacuum pump I, it is equipped with pressure transmitter to preblend gas piston chamber and ball valve between II, the constant volume burning ware is gone into antilinear ball valve II and is connected with pressure transmitter, the export of constant volume burning ware is connected through ball valve V and vacuum pump II, the nitrogen gas gas pitcher is connected with solenoid valve IV through pressure control valve IV, IV exit ends of solenoid valve are connected with high -pressure nitrogen gas room, through the utility model discloses a system can realize pre -burning gas mixture one -tenth distribution ratio and preblend gas transporting, initiatively changes the interior temperature of constant volume burning ware, pressure, density and gas composition, reaches control burning initial condition's purpose.
