Description
Technical Field
The utility model belongs to the technical field of equipment sealing, and particularly relates to an online sealing device for pressure equipment.
Background
The top or bottom of the pressure equipment is usually reserved with a plug for drainage or exhaust, and the plug is connected above the pressure equipment through a threaded structure. In order to ensure the sealing of the plug, the sealing is usually realized by winding a raw material belt or smearing sealant on the threaded part of the plug. However, the reliability of the sealing mode is low, the condition that the plug is leaked out often occurs in the running process of the unit, the pressure-bearing equipment is required to be taken out of the running when the defects are usually treated, and the raw material belt is wound on the thread position or the sealing glue is smeared after the plug is removed.
The existing online sealing technology is also mature and perfect continuously, the online sealing is to plug the external leakage point by corresponding plugging means when the pressure equipment is in an operation state, eliminate the leakage point of the pressure equipment, and further treat the leakage point after the pressure equipment is out of operation. The on-line sealing belongs to an emergency treatment means, and can reduce the time of unit shutdown and improve the economy of the unit.
At present, the online sealing technology for the plug mainly comprises the following modes: the first is to carry out the caulking treatment to the edge of the plug, the second is to carry out the welding treatment to the edge of the plug, and the third is to carry out the glue injection treatment to the plug. Compared with the above treatment modes, the first type of the twisting seam treatment operation is fast, but the time for maintaining the sealing of the twisting seam is short, so that leakage is easy to occur again. The second welding mode is adopted, and the medium leaks outside, so that the welding process requirement is high, and the welding quality cannot be ensured. The combination of glue injection or seam twisting and glue injection is generally the most reliable on-line sealing treatment method. Before injecting glue, the plugging cap is required to be installed outside the leakage point, glue is injected into the plugging cap, at present, a welding fixing mode is generally adopted between the plugging cap and equipment, and after the pressure-bearing equipment is withdrawn from operation, the plugging cap is required to be removed, and glue injection residues are removed.
The fixing mode of the plugging cap and the pressure-bearing container has great influence on the rapidness of subsequent disassembly, if the plugging cap adopts a welding mode, the plugging cap needs to be cut, certain damage can be generated on the outer surface of the pressure-bearing container, and the plugging cap is not easy to disassemble.
