Fig. 2 is a top view of the internal structure of the present invention.
Fig. 3 is a schematic structural view of the utility model after the lower part in the pipeline is sealed.
Detailed Description
As shown in fig. 1-3, a pipeline internal plugging device comprises a hollow elastic sealing disk 2, wherein the elastic sealing disk 2 is an elastic rubber sealing disk, an upper arc-shaped ring 3 is arranged in the elastic sealing disk 2, a lower arc-shaped ring 4 is arranged in the elastic sealing disk 2 below the upper arc-shaped ring 3, the upper arc-shaped ring 3 and the lower arc-shaped ring 4 form a circular ring, the circular ring is concentric with the elastic sealing disk 2, vertical insertion blocks 6 are fixed at two ends of the upper arc-shaped ring 3, vertical insertion slots 5 are arranged at two ends of the lower arc-shaped ring 4, the insertion blocks 6 are slidably inserted into the insertion slots 5 at one side of the insertion blocks, a vertical double-end telescopic cylinder 7 is arranged between the upper arc-shaped ring 3 and the lower arc-shaped ring 4, the double-end telescopic cylinder 7 is a hydraulic cylinder, telescopic rods at the upper side and the lower side of the telescopic cylinder 7 are respectively fixedly connected with the upper arc-shaped ring 3 and the lower arc-shaped ring 4, and the double-end telescopic cylinder 7 is communicated with a high-pressure hose 8, the high-pressure hose 8 penetrates the front end of the elastic sealing disc 2.
The utility model discloses during the use, put into pipeline 1 with it through 1 port of pipeline, and make bi-polar telescoping cylinder 7 keep vertical state, then make high-pressure hose 8 and hydraulic pump intercommunication, start-up hydraulic pump makes the telescopic link extension of bi-polar telescoping cylinder 7, when the telescopic link of bi-polar telescoping cylinder 7 extended, go up arc ring 3 and keep away from each other with lower arc ring 4, it makes the upper portion of elastic seal dish 2 outer fringe and lower part respectively to tightly support the upper portion and the lower part of pipeline 1 inner edge to go up arc ring 3 and lower arc ring 4, thereby realize blocking pipeline 1 internal lower part shutoff and block, thereby can block remaining liquid in the pipeline, then carry out the welding operation after discharging the liquid in the pipeline 1 of this device front side. After the welding operation is completed, the telescopic rod of the telescopic cylinder 7 retracts, the elastic sealing disc 2 is restored after the upper arc-shaped ring 3 and the lower arc-shaped ring 4 are restored, and then the device can be conveniently taken out from the pipeline 1.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
