The invention discloses a leakage plugging device for a pressure pipeline, which comprises a pipeline. One end of the pipeline is contacted with a support plate, and a chute is provided in the support plate. There are two chute slots, and the two chute slots Symmetrically distributed in the support plate, a support rod is slidably connected in the chute, a stopper is welded to one end of the support rod, a guide rod is arranged in the chute, and the guide rod is welded on the support plate. The outer side of the guide rod is provided with a first spring, the outer side of the guide rod is slidably sleeved with a backing plate, the outer side of the guide rod is slidably sleeved with a support rod, the backing plate is in contact with the support rod, and the first One end of a spring is bonded to the support plate, and the other end is bonded to the backing plate. The invention relates to a leakage plugging device for a pressure pipeline, which has the characteristics of convenient operation and good sealing performance.
Description
technical field [0001] The invention belongs to the technical field of pipeline plugging, in particular to a pressure pipeline leakage plugging device. Background technique [0002] In modern production, there are various pipelines for water, oil, and gas transmission, and there are water pipes, gas pipes, and heating pipes in living facilities. Due to ground subsidence, external force impact, and man-made damage, the pipeline ruptures, especially the cracking of the weld seam, causing oil, gas, and water leakage. It must be repaired in time, otherwise it will not only cause waste of resources, affect production and life, but also cause environmental pollution. . Because there is no special-purpose pipeline plugging device, the general repair method is to cut off the water or gas first, stop the normal operation of the fluid in the pipeline, and then replace with new pipe fittings or weld repairs or block with other materials. The above method must be maintained by profess...
