Description
Technical Field
The utility model relates to a non-metal pipeline plugging device which is mainly applied to pipeline pressure test at the tail end of a non-metal pipeline section, in particular to a sewage discharge pipeline system in an offshore oil platform living building.
Background
At present, a wooden plug is generally adopted for plugging a sewage discharge pipeline system in an offshore oil platform living building, and the wooden plug is required to be pressed into a water outlet for plugging with larger force due to larger pipeline height difference, but the strength of a non-metal pipeline cannot be compared with that of a metal pipeline, so that the method has the risk of damaging materials. In the conventional layering pressure test mode, a flange is added on each layer of a pipeline vertical pipe, water is filled in layers during pressure test, the flange is plugged by a blind flange, and a water outlet is plugged by a cork. Because the sewage discharge pipeline pipe diameter of the living building is larger, the pipeline well penetrates through the top layer to the bottom layer in general, the space of the pipeline well is relatively narrow, the construction of plugging on the flange is difficult when the flange and the pressure test are additionally arranged, and the leakage point is also increased due to the arrangement of the layered flange. The layering pressure test of the same system can also increase the frequency of pressure test, and the use amount of pressure test vulnerable materials is increased.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, and provides a non-metal pipeline plugging device which can be used for integrally plugging a pipeline on the premise of meeting the strength of a non-metal pipeline, so that the construction difficulty and the pressure test difficulty are reduced.
In order to achieve the above purpose, the technical scheme adopted is as follows:
the utility model relates to a nonmetallic pipeline plugging device which comprises an upper pressing plate and a lower pressing plate which are arranged in parallel at intervals, wherein a compressed rubber column is arranged between the upper pressing plate and the lower pressing plate, a fastening bolt which is arranged along the vertical direction sequentially penetrates through the lower pressing plate, the compressed rubber column and the upper pressing plate (4) from bottom to top, the upper end of the fastening bolt is screwed with a nut, the nut is tightly pressed on the upper pressing plate, the bolt head of the fastening bolt is connected with the lower pressing plate in a welding way, the diameter of the upper pressing plate is larger than the diameter of a nonmetallic pipeline to be plugged, and the diameters of the lower pressing plate and the rubber column are smaller than the diameter of the nonmetallic pipeline.
The utility model has the advantages that: the nonmetallic pipeline can be subjected to pressure test integrally, a layering flange is not required to be additionally arranged, the space of a pipeline well is saved, and meanwhile, the construction difficulty of pipeline installation is reduced; the nonmetallic pipeline can be used for integrally testing pressure, so that the pressure testing times are reduced, the design workload and the construction workload are reduced, and the material cost is saved.
