Description
Technical field
The present invention relates to the maintenance unit of refining device technical field, the leak stoppage device of the low row of especially a kind of petrochemical equipment.
Background technique
For ease of overhauling equipment in Oil Refining, purging, pressure release, prior art is provided with low arranging device usually in pipeline, and when equipment in Oil Refining runs well, low arranging device is but in static, long-time off position, for this reason, also become the most easily by link that people ignore.Problems existing is, because the pipeline of equipment in Oil Refining is in the environment of aggressive medium for a long time, belong to again inflammable, explosive, high temperature, high pressure conditions, the pipe cap that low valve door causes because of corrosion, plug corrosion, cause the phenomenon of leakage of common occurrence, in addition pipe cap, the plug dismounting difficulty of corrosion leakage, cannot change in time again in equipment runs well, this leakage phenomenon not only causes wastage of material, and operation energy consumption improves, and there is great potential safety hazard.
Summary of the invention
The leak stoppage device of the low row of a kind of petrochemical equipment provided for the deficiencies in the prior art is provided, the present invention takes jig main body and the direct-connected mode of pipeline, leak stopping can be implemented not stopping, under the safe condition of not getting angry, there is simple, the easy to operate and advantage that plugging effect is good of structure.
The concrete technological scheme realizing the object of the invention is:
The leak stoppage device of the low row of a kind of petrochemical equipment, its feature comprises jig main body, pressing plate, sealing gasket, puller bolt and lock bolt, described jig main body is bottomed cylindrical, the outer wall of its cylinder opening end is provided with flange circle, inwall is provided with the ring muscle of several projection, axle center at the bottom of cylinder is provided with and holds out against screw, the opening end of jig main body is provided with otch flange circle and partial cylinder cut, and otch crosses the center of circle of jig main body, the bolt hole vertical with otch and tapped hole is provided with in the radial direction of flange circle, the head radial direction of puller bolt is provided with through hole, rocking bar is installed with in through hole, described pressing plate, sealing gasket are placed in the cylinder of jig main body successively, and puller bolt engages with the screw that holds out against of jig main body, and lock bolt is two pieces, engage in the bolt hole being located at jig main flange circle with tapped hole.
The present invention takes jig main body and the direct-connected mode of pipeline, can implement leak stopping not stopping, under the safe condition of not getting angry, and has simple, the easy to operate and advantage that plugging effect is good of structure.
