The utility model provides a in the thermal power factory, low pressure steam-water system pipeline, oil system pipeline need not system's pipeline outage to keep apart under the defect fault condition such as pipeline sand hole, pipeline corrosion, pipeline welded junction and carry out the leaking stoppage on line in the operation process, avoided the leakage to enlarge the abnormal event that causes main equipment or unit non-to stop.
Description
Technical Field
The utility model belongs to the technical field of the pipeline mending leakage, concretely relates to a plugging device that is used for pipeline sand hole, corruption and welding defect to leak.
Background
In a thermal power plant or other fields, in the process of system operation, low-pressure steam-water system pipelines and oil system pipelines, pipeline sand holes and the like occur in the system pipelines in the operation process due to the phenomena of pipeline manufacturing quality or material, corrosion, welding quality and the like, so that leakage is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a plugging device that is used for pipeline sand hole, corruption and welding defect to leak to solve above-mentioned problem.
In order to achieve the above object, the utility model discloses a technical scheme be:
the utility model provides a plugging device that is used for pipeline sand hole, corruption and welding defect to leak, includes the welded plate, wears to establish the leak source intercommunication of through-hole and pipeline on the welded plate, and the fixed communicating pipe that sets up on the welded plate, the one end and the through-hole of communicating pipe link up, and the other end sets up the flange, and the tail end of flange sets up the valve body.
In order to further realize the utility model discloses, the diameter of through-hole is 5 times of the leak point diameter at least.
In order to further realize the utility model discloses, the welding plate is the arc, and the outer wall laminating of its inner wall and pipeline is just fixed.
In order to further realize the utility model discloses, the internal diameter of communicating pipe is not less than the external diameter of through-hole.
In order to further realize the utility model, the length of the communicating pipe is 20-30 cm.
In order to further realize the utility model discloses, the material of welded plate and communicating pipe is the same with the pipeline.
The utility model discloses compare in prior art's beneficial effect do:
the utility model discloses well design welded plate welds with the pipeline outer wall that takes place to reveal, improve the rigidity of taking place the pipeline damage department of revealing, position corresponding with the leakage point on the welded plate sets up welding communicating pipe and valve body behind the through-hole, the structure and the installation method of this device are compared in the welding of traditional direct mending-leakage, not only reduce the welding degree of difficulty, can also effectively improve the intensity of connecting, the pressure dispersion that will reveal the point is to in communicating pipe and the new construction that the valve body constitutes, and this device is makeed in advance, weld from communicating pipe inside and leakage point under the valve body open mode and compare in traditional mending-leakage method easier, can greatly reduced overhaul workman's the work degree of difficulty, improve labor efficiency.
The utility model provides a in the thermal power factory, low pressure steam-water system pipeline, oil system pipeline need not system's pipeline outage to keep apart under the defect fault condition such as pipeline sand hole, pipeline corrosion, pipeline welded junction and carry out the leaking stoppage on line in the operation process, avoided the leakage to enlarge the abnormal event that causes main equipment or unit non-to stop.
