Abstract

The invention relates to a combustible gas pipeline jet fire experiment device with an adjustable angle and an adjustable distance. The device comprises a lower supporting piece and a nozzle aligned with a spraying target; a distance adjusting device is arranged above the lower supporting piece; the nozzle is detachably connected to the distance adjusting device; the distance adjusting device is used for adjusting the distance between the nozzle and a spraying target; one end of the distance adjusting device is hinged to one end of the lower support; the other end of the distance adjusting device is movably connected to the other end of the lower supporting piece; an angle adjusting device is fixedly connected to one side of the lower supporting piece; the distance adjusting device is rotationally connected to one side of the angle adjusting device; and a plurality of angle locking positions used for fixing the distance adjusting device and the angle adjusting device are sequentially arranged on the angle adjusting device along the rotating stroke of the distance adjusting device. And the distance between the nozzle and a spraying target can be conveniently adjusted through the distance adjusting device. The distance adjusting device rotates around the hinged position of the distance adjusting device and the lower supporting piece, and the spraying angle of the sprayer is conveniently adjusted.

Description

technical field [0001] The invention relates to the field of experimental devices, in particular to a combustible gas pipeline jet fire experimental device with adjustable angle and spacing. Background technique [0002] Restricted by geographical and economic factors, natural gas pipelines are increasingly being laid in parallel or across. During the operation of parallel or intersecting pipelines, if one of the pipelines fails and a jet fire accident occurs, the continuous flame impact or strong heat radiation in the near field will probably cause the adjacent pipelines to fail, causing the domino effect of accidents and causing even more accidents. for serious accident consequences. Therefore, it is very important to analyze the impact of the initial failure pipeline jet fire accident on the adjacent target pipeline for the safety of pipeline laying design and operation. [0003] In order to simplify the experimental process in the research process, the general experime...
