Quick plugging kit for clamping-type pipeline

Abstract

The invention relates to a quick plugging kit for a clamping-type pipeline, belonging to the field of mechanical engineering. The kit consists of a closed ring and a locking device; and the locking device is fixed on the closed ring by bolts and nuts. The closed ring consists of a left half ring, a right half ring and a main pin shaft, wherein the left half ring and the right half ring are embedded and connected with each other by the main pin shaft. The locking device consists of a base fixing pin shaft, a handle base, rivets, a handle, a handle pin shaft, a U-shaped elastic pulling rod, a clamping hook, an adjusting nut, a fixed bolt and a nut, wherein the base fixing pin shaft is connected with the handle base; the handle is connected with the handle base by the handle pin shaft; the handle is connected with the handle base by the rivets; the clamping hook is fixed on a reversely-coiled lug sheet of the left half ring; the handle pin shaft passes through the handle; and the U-shaped opening end of the U-shaped elastic pulling rod passes through holes at two ends of the handle pin shaft respectively. The quick plugging kit can be used for quickly plugging various leaked pipelines without stopping water or gas; and compared with a traditional pipeline plugging method, the quick plugging kit can be operated conveniently and quickly, saves effort and time, and has a good effect.

Description

technical field [0001] The invention relates to a pipeline engineering fitting, in particular to a clamping type pipeline quick plugging kit which can be quickly repaired without stopping the pipeline work when the pipeline for transporting fluid is damaged, belonging to the field of mechanical engineering. technical background [0002] As we all know, various damage and leakage accidents often occur in pipelines in use. As long as the leakage occurs, economic losses will be caused. Effective measures to stop leakage must be adopted as soon as possible. Usually, the method of plugging the steel pipe is welding, and the pipeline with cracks and cracks will be repaired and welded, but the repair welding method has the following problems: the repair welding on the oil and gas pipeline must require the pipeline to stop conveying the medium, otherwise the repair welding will explode, and the pipeline will explode during transportation. Repair welding on the water pipeline is ofte...

[0002] As we all know, various damage and leakage accidents often occur in the use of pipelines, as long as the leakage will cause economic losses, effective plugging measures must be taken to plug the leak as soon as possible

Usually, the method of leak plugging of steel pipes is welding, and the pipes with cracks and cracks will be repaired and welded, but the repair welding method has the following problems: repair welding on oil and gas pipelines must require the pipeline to stop conveying medium, otherwise repair welding will cause explosions Welding repairs on water pipes are often inoperable due to the spray of water columns at the cracks, and the pipes also need to stop transporting media

However, this structure and method are used to repair damaged pipelines. Its production and installation are more complicated, and there are too many connectors, and the phenomenon of leakage occurs from time to time due to insufficient sealing.

[0005] There are defects and deficiencies in the above-mentioned existing repairing and plugging methods about pipeline leakage, which need to be improved and perfected urgently.
