Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, specifically referring to a pipeline connection sleeve. Background Art

[0002] A pipeline is a device formed by connecting pipes, pipe fittings, valves, etc. for transporting gases, liquids, or fluids with solid particles. Pipelines have a wide range of uses, mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations. The usage environments of pipelines are also diverse, such as underwater, in soil, etc. The length of pipelines is limited, so the connection mechanism between pipelines is crucial. In the prior art, when connecting two pipelines through a sleeve joint on the ground, generally, a sleeve joint is first installed on one pipeline, and then the other pipeline is connected to the above sleeve joint. Before connection, the outer walls of the two pipelines need to be positioned with straps to prevent displacement, which is inconvenient to operate, has insufficient sealing performance, and low installation efficiency. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the problems in the background art and provide a pipeline connection sleeve.

[0004] To solve the above technical problems, the technical solution provided by the utility model is: a pipeline connection sleeve, including a connection sleeve body, a positioning card is arranged in the middle of the inner side of the connection sleeve body, annular flaring mouths are arranged on the connection sleeve body on both sides of the positioning card, and a flexible sealing ring is arranged between the annular flaring mouth and the pipeline to be connected.

[0005] Preferably, the positioning card is an annular positioning card.

[0006] Preferably, the inner diameter of the connection sleeve body is slightly larger than the pipeline to be connected.

[0007] Preferably, the inner diameter of the connection sleeve body is 20 - 1800 mm.

[0008] The utility model has the following advantages: reasonable structural design, placing the flexible sealing ring in the annular flaring mouth of the sleeve, and inserting the pipelines with corresponding diameters into the sleeve respectively to achieve connection and sealing, with good sealing performance, convenient construction, and high installation efficiency.
