Description

Technical Field

[0001] The present application relates to the technical field of waterproofing and leak-proofing, and in particular to a pipeline leak-proofing device. Background Art

[0002] In the heavy industry of steel mills, the recycling of water resources is not only an important environmental protection measure, but also a key link in improving production efficiency and reducing operating costs. In the steel production process, a large amount of cooling water, process water, etc. need to be reused after treatment to reduce dependence on natural water resources. In this circulation system, the water intake pipe is a key component connecting the water source and the water treatment facilities. Its stability and sealing are directly related to the operating efficiency and safety of the entire water circulation system.

[0003] However, in actual application, the seal between the water suction pipe and the wall is filled with filler in the gap between the two, and the outside is sealed with concrete in an annular wrapping; during the daily water supply process, the pipe will have slight vibrations, and as time goes on, the joints between the pipe and the wall will leak. Once a leak occurs, the pipe will be continuously impacted by the water flow at the gap, which will accelerate the corrosion of the pipe, and the gap will gradually become larger, causing a waste of water resources. If the leak is too large, it may cause the water level in the pool to drop sharply, resulting in the inability of the water pump to pump water, and then causing the entire production system to stop production. If the leak needs to be sealed, the pool needs to be emptied before sealing, which is time-consuming and labor-intensive, affecting the production rhythm, so it needs to be improved. Utility Model Content

[0004] In order to solve the problem of water leakage at the joint between the pipeline and the wall, the present application provides a pipeline leakage plugging device.

[0006] A pipeline plugging device comprises a block arranged on the pipeline, a first pressure ring is arranged on one side of the block, a sleeve ring is arranged on the side of the first pressure ring away from the block, a second pressure ring is arranged on the side of the sleeve ring away from the first pressure ring, a first sealing gasket for filling the gap between the pipeline and the wall is arranged on the side of the second pressure ring away from the sleeve ring, the first pressure ring, the sleeve ring, the second pressure ring and the first sealing gasket are arranged in sequence from the block toward the pipeline wall, a pressure relief pipeline is arranged on the sleeve ring, the pressure relief pipeline is connected with the inside of the pipeline, and an overflow valve is arranged on the pressure relief pipeline.

[0007] Since the pipeline will vibrate slightly during the daily water supply process, as time goes by, the joints between the pipeline and the wall will leak. Once leakage occurs, the pipeline will be corroded due to the continuous impact of water flow at the gap, and the gap will gradually become larger, causing a waste of water resources. By adopting the above technical solution, including a block, the block is welded and fixed on the pipeline, and the block is sequentially installed with a first pressure ring, a sleeve ring, a second pressure ring and a first sealing gasket in the direction of the pipeline wall; through the close fit of the first sealing gasket and the compression of the multi-layer pressure ring, the device can effectively fill and seal the joint between the pipeline and the wall to prevent water from flowing from the joint. The block, the first pressure ring, the sleeve ring and the second pressure ring are stacked layer by layer to form a stable structural system, which can resist the tiny displacement of the pipeline caused by water flow impact or natural vibration, and can also enhance the connection strength between the pipeline and the wall to a certain extent, and improve the stability of the entire water supply system.

[0011] By adopting the above technical solution, the circumferential ring is opened on both sides of the second sealing gasket; through the setting of the circumferential ring, the contact area between the second sealing gasket and the block and the first pressure ring can be increased, thereby providing a tighter sealing effect and effectively filling the tiny gap between the sealing surfaces.

[0012] Optionally, the number of the first pressure rings is two, any one of the first pressure rings is semicircular, and an area for fixing to the pipeline is formed between the two first pressure rings.

[0013] By adopting the above technical solution, the first pressure ring is semicircular, and the number of the first pressure rings is two; through the selection of the first pressure ring, the two semicircular first pressure rings can be tightly wrapped on the pipe, and together with the second sealing gasket and the ring and other components, a complete sealing system is formed, which can more effectively reduce the leakage of water from the joint between the pipe and the wall, improve the reliability and durability of the seal, and at the same time it is convenient to install and easy to operate.

[0014] Optionally, a plurality of fixing bolts for fixing are provided between the two first pressure rings, and the plurality of fixing bolts are sequentially arranged at the connection between the two first pressure rings.

[0015] By adopting the above technical solution, the two first pressure rings are fixed by fixing bolts; by setting the fixing bolts, the tight connection can ensure that the sealing gasket (such as the second sealing gasket) between the first pressure ring and the pipeline is subjected to sufficient pressure, thereby maintaining the tightness of the seal. Tight sealing is the key to preventing water from leaking from the joint between the pipeline and the wall.

[0016] Optionally, a third sealing gasket for sealing is provided between the two first pressure rings.

[0017] By adopting the above technical solution, the third sealing gasket is installed between the two first pressure rings; through the provision of the third sealing gasket, the possible small gap between the two first pressure rings can be filled to ensure the integrity of the entire sealing structure.

[0018] Optionally, a slope for assembly is provided on one side of each of the first pressure rings, and the slope is provided on a side of the first pressure ring close to the sleeve ring.

[0019] By adopting the above technical solution, a bevel is provided on the first pressure ring; through the setting of the bevel, the bevel can be used as a guide surface, making it easier to align and install the components, reducing the difficulty and time of assembly, and facilitating assembly and positioning.
