Description
Technical Field
The utility model belongs to the technical field of pipeline plugging, and particularly relates to a portable temporary plugging device for a pipeline under pressure.
Background
In the use of heat supply and water supply pressure-bearing pipelines of waste heat power generation projects, the maintenance and the use of the pipelines are part of daily work, and 'small accidents' of 'running and leaking' are frequently encountered in the use process, so that the accidents are mainly caused by uneven inner side of the pipeline wall or pits caused by corrosion of scale, and when water or steam in the pipelines flows through the pits, the pits are corroded by vortex acceleration of the inner walls of the pipelines, so that 'sand holes' are formed in the pipelines, and air leakage and water leakage begin. Once such a "minor accident" occurs, control must be remedied and if left free, the leak will become larger under steam or water attack until control cannot be remedied. Therefore, once the phenomenon occurs, the best method is to replace the pipeline, but the pressure and the temperature of the boiler and the pipeline can not be completely stopped at one half moment, the pipeline can be replaced only after the temperature is reduced and the pressure is reduced, the process generally lasts for 2-3 days, and when the pipeline can not be stopped in time in the process of stopping the pressure reduction of the boiler and the pipeline or in the short period of pipeline leakage, leakage points are easy to diffuse, and the leakage stoppage under pressure needs to be carried out in time.
The existing pressure plugging mode is usually to glue or weld plugging sheets on the pipeline outside the leakage point, wherein the glue type plugging sheets have low pressure bearing capacity, are easy to open glue and easily cause secondary leakage, and the welding type plugging sheets are not suitable for pipelines with too thin pipe walls and are also not suitable for pipelines for transporting inflammable mediums.

portable pipeline temporary plugging device under pressure includes:
the fixing assembly comprises two semicircular pipe clamps, a fixing structure is arranged between the two pipe clamps, a blocking hole is formed in one pipe clamp, and a sealing port nut is fixedly arranged on the outer side of the blocking hole;
the sealing assembly comprises a sealing bolt matched with the sealing port nut, a sealing gasket is arranged at the screw head of the sealing bolt, and a rotating handle is arranged on the screw cap of the sealing bolt.
As a preferred technical solution, the fixing structure includes a connecting bolt connecting the two pipe clamps and a fastening nut cooperating with the connecting bolt.
As a preferable technical scheme, the sealing gasket is a rubber sealing gasket.
As a preferable technical scheme, the sealing gasket comprises a conical plugging part and an annular sealing part, wherein the conical plugging part and the annular sealing part can extend into the plugging hole.
Due to the adoption of the technical scheme, the utility model has at least the following beneficial effects:
