The invention discloses a channel type four visual angles X ray liquid state article safety inspection system, which is composed of a system control and signal processing circuit unit, a first bench acquisition computer, a second bench acquisition computer, a third bench density computer, a switch, a conveyer, a transfer channel, four groups of X radiation source and four groups of detectors, and the first bench acquisition computer, the second bench acquisition computer and third bench density computer are connected through a local network. The safety inspection system has the following advantages that 1) the inspection capability is strong, the liquid dangerous products with different sizes and different materials can be effectively detected; 2) the inspection speed is fast, and six liquid can be simultaneously detected; and 3) the detection sensitivity is high and the detection is accurate. In addition, the safety inspection system has strong anti-interference capability, and is suitable for a safety check system in important places such as civil aviation, railway and customs.
