Technical Field
The utility model relates to a technical field is repaired to the pipeline, in particular to leak stoppage device is under being under construction under steel pipe conduit normal operating condition.
Background
The large-caliber steel pipe is commonly used in water delivery engineering, when a water delivery pipeline leaks water, firstly, a patch is welded and repaired in a water cut-off state, and water supply to downstream users is influenced by water cut-off operation, so that economic loss and social influence are caused; and moreover, the hoop method is adopted for plugging, the construction difficulty of the hoop method is high for a large-diameter water delivery steel pipe, the cost is high, and the hoop needs to be maintained again after water leakage repeatedly in the future.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above problem, a steel pipe plugging device suitable for the operation of not cutting off the water supply is provided, with low costs, simple structure, convenient operation is simple easily learned.
The technical scheme is as follows:
the utility model provides a steel pipe plugging device, includes patch board, aqueduct, valve, drainage three-way pipe and a plurality of positioning bolt, its main points are the patch board be with conduit steel pipe assorted arc, a plurality of positioning bolt are fixed the setting respectively on conduit steel pipe outer wall, are provided with a plurality of screws on the peripheral panel of patch board respectively, a plurality of positioning bolt insert respectively and establish in a plurality of screws, the cover is equipped with the nut respectively on a plurality of positioning bolt. An annular sealing rubber pad is fixedly arranged on the lower end face of the patch board, a water guide hole is formed in the middle of the patch board, and the lower end of the water guide pipe is seated on the water guide hole and is fixedly connected with the upper end face of the patch board; the lower end opening of the valve is connected to the upper end opening of the water guide pipe in a sealing mode, the opening of the lower end of the three-way drainage pipe is connected to the upper end opening of the valve in a sealing mode, a plug is fixedly arranged on the opening of the upper end of the three-way drainage pipe, and the transverse water pipe of the three-way drainage pipe is a drainage pipe.
A blind flange is fixedly arranged on the upper port of the valve.
The patch board of the utility model is customized to have the same radian according to the diameter of the steel pipe of the water pipeline, a plurality of positioning bolts are fixedly welded near the leakage point of the steel pipe, a valve on the water guide pipe is opened, and the water guide pipe is externally connected with a common water drainage pipe to discharge water to a remote place; and pushing a plug on the drainage three-way pipe along the axial direction of the water guide pipe by means of external force (an excavator bucket can be adopted) to transmit the force to the patch plate to tightly press the sealing rubber pad, fastening a nut on the positioning bolt, welding the periphery of the patch plate and the water pipe steel pipe by using electric welding under the condition that no water is leaked or the leakage amount is small around the patch plate, closing the valve after the welding is finished, removing the drainage three-way pipe behind the valve, and installing a blind flange on a flange and a rubber pad on the valve.
The utility model discloses can be under the normal operating condition of conduit, need not to cut off the water supply. The leaked water is discharged out of the construction working face through the drain pipe, so that a better installation working environment is created; if a gap exists between the periphery of the patch board and the steel pipe, the nut at the corresponding position can be fastened to reduce the gap, and then electric welding is adopted for welding for multiple times, so that the periphery of the patch board is ensured to be watertight; after the periphery of the patch board is welded, the positioning bolt and the periphery of the nut are welded by electric welding in the same way, so that water leakage from the periphery of the positioning bolt and the nut is prevented; in the installation process, the plug on the drainage three-way pipe can be jacked by external force (adopting a bucket of an excavator), so that the operation difficulty is reduced; after welding, the valve is closed, and the blind flanges are arranged on the flange of the valve and the rubber pad, so that water leakage can be prevented when the valve is damaged.
The utility model discloses the great bore steel pipe in the mainly suitable water delivery engineering, it is lower to make the degree of difficulty, can make multiple specification reserve in advance, practices thrift the rush-repair time, and installation easy operation easily learns, and the cost is lower, has wide market space.
