Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a small and medium-sized water conservancy project pipeline connection component. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc., and the laying of water conservancy pipelines to achieve their goals. Pipeline connection components are required when laying water conservancy pipelines.

[0003] For example, in the case of application number CN220268733U, a sealing cover is used in conjunction with a sealing ring 2 to seal both ends of the bolts of the flange connection, thereby protecting both ends of the bolts. At the same time, a sealing ring 1 on the outside of the flange can be used to prevent external moisture from entering through the flange connection seam to corrode the bolts. The entire structure can effectively protect the bolts of the flange connection, increase the service life of the bolts, and minimize the leakage hazards caused by loose flange connections due to bolt corrosion. However, the sealing effect of the pipeline connection assembly is general, and the long-term impact of the flow of the medium inside the pipeline can easily cause the sealing ring to lose its sealing effect, causing the pipeline to leak, resulting in certain economic losses.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a pipeline connection component for small and medium-sized water conservancy projects is proposed. Utility Model Content

[0007] Preferably, the limiting assembly comprises a metal baffle and a rubber outer lining, and the outer surface of the metal baffle is provided with the rubber outer lining.

[0008] Preferably, the inner surface of the sealing ring A is fitted with an engineering pipeline component A, and the right side of the engineering pipeline component A is connected to the engineering pipeline B.

[0009] Preferably, the inner diameter of the sealing ring A is smaller than the inner diameter of the sealing ring B, and the inner diameter of the sealing ring B is smaller than the inner diameter of the sealing ring C.
