[0002] When the natural gas pipeline transports natural gas overpressure, it is necessary to release the excess gas in the natural gas to reduce the natural gas pressure in the pipeline. When the natural gas pipeline needs to be repaired, it is also necessary to release the natural gas in the pipeline to carry out maintenance. Generally, through operation Personnel observe the pressure gauge to check the pressure in the pipeline, and then directly release the natural gas through manual operation, which may cause the operator to fail to observe or accurately observe the pressure of the pressure gauge when the pressure of the natural gas in the pipeline is too high, causing the natural gas to explode.

The invention discloses an emergency diffusion device for medium-high pressure natural gas pipes. The device comprises a diffusion box, wherein a pipe is fixedly mounted on the bottom surface of the diffusion box, and a pipe cavity is formed in the pipe; a disk drives a second gear to rotate, and the second gear rotates to drive a rotating rod to rotate; when natural gas pressure in the pipe cavity is too high, a moving block moves upwards and drives a rack to move upwards; the rack enables an auxiliary block and a connecting rod to move downwards through a first gear, and the connecting rod drives a transmission rod to rotate, so that natural gas in the pipe cavity enters a storage cavity through a transmission cavity, pressure of the natural gas in the pipe cavity can be relieved in time, then the natural gas in the storage cavity is transported to a combustion cavity through left-right movement of a spring plate, an igniter ignites the natural gas to combust the natural gas, and environmental pollution is prevented.
