Leakage-removing joint

The utility model provides a leakage-removing joint. The leakage-removing joint comprises a low-pressure raffinate channel, a high-pressure raffinate channel and a liquid draining channel, wherein one end of the liquid draining channel is open, and the other end of the liquid draining channel is sealed and longitudinally arranged at the bottom of the leakage-removing joint; the low-pressure raffinate channel is formed in the first side wall of the leakage-removing joint and communicated with the liquid draining channel; the high-pressure raffinate channel is formed in the second side wall of the leakage-removing joint and communicated with the liquid draining channel; an inner end opening of the low-pressure raffinate channel is deviated from the inner end opening of the high-pressure raffinate channel. The leakage-removing tube joint provided by the utility model adopts an asymmetrical design of high-pressure raffinate and low-pressure raffinate, so that sprayed high-pressure raffinate does not directly enter a low-pressure raffinate pipeline, and therefore, an engine damage rate caused by raffinate leakage is lowered.
