Leakage-proof high-pressure oil pipe of high-power diesel engine

The utility model relates to the technical field of diesel engine high-pressure oil pipes, and discloses a high-power diesel engine leakproof high-pressure oil pipe which comprises a pipe body, a protection pipe is fixedly installed on the outer surface of the pipe body, a buzzer and an alarm lamp are fixedly installed on the outer surface of the protection pipe, and two liquid guide pipes are fixedly communicated with the outer surface of the protection pipe. A pressure sensor is fixedly mounted on the outer surface of each liquid guide pipe, and the sensing end of each pressure sensor penetrates through the corresponding liquid guide pipe and extends into the corresponding liquid guide pipe; when the pipe body is broken, oil liquid can flow into the liquid guide pipe through a gap between the protection pipe and the pipe body and then flow into the connecting pipe, at the moment, due to the fact that pressure can push the sealing plate to move rightwards and the telescopic spring shrinks, fuel oil can flow
