Description

Technical Field

[0001] This utility model relates to the field of oil pipeline crack sealing technology, and more specifically, to an oil pipeline crack sealing device. Background Technology

[0002] Oil pipelines are one of the main pieces of equipment in the oil storage and transportation industry. They consist of pipes and accessories, and are equipped with corresponding oil pump units according to the needs of the process flow, forming a complete pipeline system for oil unloading and transportation. Oil pipelines are generally made of steel pipes, connected by welding and flanges to form long pipelines, and valves are used for opening and closing control and flow regulation. Oil pipelines often crack due to external forces or internal air pressure, leading to oil leaks and unnecessary losses. To repair cracks in oil pipelines, pipeline maintenance personnel use pipeline sealers to seal them. However, existing pipeline crack sealers rely solely on rubber rings for sealing, which is ineffective. Furthermore, when existing sealers are fixed with bolts and nuts, these parts are directly exposed to the external environment, which can cause the sealer to loosen, affecting the sealing quality. Therefore, we propose an oil pipeline crack sealer. Summary of the Invention

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide an oil pipeline crack sealing device.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A crack sealing device for an oil pipeline includes an oil delivery pipe. Two arc-shaped sealing shells are fitted around the outer side of the oil delivery pipe. An inner rubber sealing gasket is provided on the inner side of each of the two arc-shaped sealing shells. An outer rubber sealing gasket is fixedly connected to both ends of the inner cavity of each of the two arc-shaped sealing shells. An injection sealing groove is provided between each of the outer and inner rubber sealing gaskets. Multiple connecting blocks are provided on the inner wall of each arc-shaped sealing shell within the injection sealing groove. The inner surfaces of the inner and outer rubber sealing gaskets are in contact with the outer surface of the oil delivery pipe. The outer side of one of the arc-shaped sealing shells... Two glue-injection tubes are fixedly connected, and one end of each glue-injection tube is threaded with an internal thread cap. One end of each glue-injection tube extends into the inner cavity of the glue-injection sealing groove. The top and bottom of one arc-shaped sealing shell are provided with a first connecting seat, and each of the two first connecting seats is provided with a screw hole. The top and bottom of the other arc-shaped sealing shell are provided with a second connecting seat, and each of the two second connecting seats is provided with a mounting hole. A fastening bolt is fitted into the inner cavity of the mounting hole, and the end of the fastening bolt is threaded into the inner cavity of the screw hole. A protective mechanism is provided on the outside of the oil delivery pipe.

At this time, the glue injection sealing grooves 5 on the inner side of the two arc-shaped sealing shells 2 form a space for filling. Then, glue is injected into the inner cavity of the glue injection sealing grooves 5 through the glue injection tube 7, so that the glue fills the space between the oil delivery pipe 1 and the arc-shaped sealing shells 2, so that the glue seals the oil delivery pipe 1 and the arc-shaped sealing shells. The shells 2 are sealed again. After the glue is injected, the inner thread cap 8 is installed on the outer thread of the glue injection tube 7. At the same time, the oil delivery pipe 1 and the arc-shaped sealing shell 2 are sealed for the third time through the outer rubber sealing gasket 4. Finally, the upper protective shell 15 and the lower protective shell 16 are fitted on the outside of the oil delivery pipe 1, so that the upper protective shell 15 and the lower protective shell 16 are fitted on the outside of the two oil delivery pipes 1. At this time, the locking block 20 on the side of the upper protective shell 15 is inserted into the locking groove 19 on the side of the lower protective shell 16, thereby connecting the upper protective shell 15 and the lower protective shell 16. At the same time, the sealing socket 22 on the lower protective shell 16 is inserted into the sealing slot 21 on the upper protective shell 15 to ensure the sealing between the upper protective shell 15 and the lower protective shell 16, so that the fastening bolt 13 connecting the first connecting seat 9 and the second connecting seat 11 can be protected by the upper protective shell 15 and the lower protective shell 16.
