The utility model discloses a natural gas pipeline leakproof device which comprises a first pipeline, a second pipeline, a clamping mechanism and a sealing cylinder. The first pipeline is communicated with the second pipeline through a flange connector. The sealing cylinder is arranged on the flange interface in a sleeving manner; the clamping mechanism comprises a first clamping plate and a second clamping plate, sealing blocks sliding in the sealing cylinder are arranged between the first clamping plate and the second clamping plate, and the sealing blocks are arranged on the two sides of the flange connector. The first sealing block and the second sealing block which are arranged in the up-down staggered mode are installed in the sealing cylinder, the first clamping plate and the second clamping plate abut against the first sealing block on each side, the screw is screwed, the distance between the first clamping plate and the second clamping plate is shortened, and therefore leakage at the flange connectin
