Problems solved by technology
[0003] At present, due to the errors caused by the production and installation of the pipeline, or the influence of the vibration during the long-term use of the pipeline, the soft joint and the pipelines on both sides of the soft joint are not concentric, and the vibration of the pipeline may also lead to the failure of the soft joint during long-term use. Excessive stretching damages the soft joint, and the above problems seriously affect the operation safety of the pipeline
[0004] In view of the above-mentioned related technologies, the inventor believes that there is a defect that the force generated by the vibration directly acts on the soft joint, making the soft joint easy to damage

The invention relates to a flexible joint pipeline correcting and fixing method which comprises the following steps that S1, a fixing device is assembled, specifically, the fixing device comprises two embracing clamps, each embracing clamp comprises a first embracing ring and a second embracing ring, and one end of each first embracing ring is hinged to one end of the corresponding second embracing ring; then a plurality of connecting screw rods are arranged between the two holding clamps in a penetrating mode, and the connecting screw rods are used for fixing the two holding clamps; s2, a fixing device is installed, specifically, one embracing clamp is clamped into the two flanges, connected with the pipeline, at one end of the flexible connector, the two flanges are clamped into the clamping grooves, and the other embracing clamp is installed on the two flanges, connected with the pipeline, at the other end of the flexible connector; s3, the pipeline is corrected, specifically, the ends, away from the hinged end, of the first embracing ring and the second embracing ring are fixedly connected through a fixing piece, and the two flanges are tightly embraced by an embracing clamp; and S4, replacing the screw rod: taking down the connecting screw rod, and then replacing the connecting screw rod with a plurality of extension limiting pieces and a plurality of shortening limiting pieces. The flexible joint correcting device has the effects of correcting and protecting the flexible joint.
Description
Technical field [0001] The present application relates to the field of pipe connection, in particular to a method of fixing pipe correction of soft joints. Background [0002] Soft joints are hollow rubber products used for flexible connections between metal pipes, which can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature changes. [0003] At present, due to the error caused by pipeline production, installation, etc., or due to the impact of vibration in the long-term use of the pipeline, the soft joint and the pipe on both sides of the soft joint are not at the same center, and the pipeline in long-term use, vibration may also lead to excessive stretching of the soft joint, so that the soft joint is damaged, the above problems seriously affect the operation safety of the pipeline. [0004] In view of the related technologies mentioned above, the inventor believes that there is a defect that the force generated by vibrat...
