Description

Technical Field

[0001] The utility model relates to the technical field of gas pipelines, in particular to a gas pipeline connector. Background Art

[0002] Gas pipelines are pipelines that transport gas (including associated gas produced by oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users. They are also called gas transmission pipelines. Using gas pipelines to transport gas is a way to transport gas in large quantities on land. Gas pipelines account for about half of the world's total pipeline length.

[0003] During the installation of a gas pipeline, due to the limited length of the pipeline itself, two pipelines often need to be butted together, but the existing gas pipeline connection device is complicated to operate and inconvenient to fix, and cannot be applied to the connection of pipelines of different diameters, and has certain limitations in use. Therefore, a gas pipeline connector is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a gas pipeline connector, which solves the problems that the existing gas pipeline connection device is complicated to operate, inconvenient to fix, cannot be applied to the connection of pipelines of different diameters, and has certain limitations in use.

[0005] The utility model is implemented as follows: a gas pipeline connector comprises a connecting sleeve, fixing sleeves are provided at both ends of the connecting sleeve, symmetrically distributed arc-shaped pressure blocks are provided inside the fixing sleeve, a fastener is provided on the fixing sleeve, the fastener is connected to the arc-shaped pressure block, a fixing block is provided at one end of the fixing sleeve close to the connecting sleeve, and the fixing sleeve is detachably connected to the connecting sleeve through the fixing block.

[0006] A further technical solution of the utility model is: a threaded hole is provided on the fixing sleeve, and the fastener is threadedly connected to the fixing sleeve through the threaded hole.

[0007] A further technical solution of the utility model is: one end of the fastener is placed outside the fixing sleeve, the other end of the fastener is placed inside the fixing sleeve, and the end of the fastener located inside the fixing sleeve is rotatably connected to the arc-shaped pressing block.

[0008] A further technical solution of the utility model is that: one end of the fixing sleeve close to the connecting sleeve is provided with connecting blocks distributed at equal distances.

[0009] A further technical solution of the utility model is: a slide groove is provided on the vertical surface of the fixing block, the connecting block is placed inside the slide groove, and the fixing sleeve is slidably connected to the fixing block through the connecting block.

[0010] A further technical solution of the utility model is: an external thread is provided on the conical surface of the fixing block, internal threads are provided at both ends of the connecting sleeve, the external thread is matched with the internal thread, and the connecting sleeve is threadedly connected to the fixing block.

[0011] A further technical solution of the utility model is that: symmetrically distributed installation cavities are arranged inside the connecting sleeve, and rubber pads are arranged at the ends of the installation cavities.

[0012] Beneficial effects of the utility model: Compared with the traditional gas pipeline connection device, the utility model uses the fasteners on the fixed sleeve to push the arc-shaped pressure plate to preliminarily fix the gas pipeline. The fixed sleeve is connected to the connecting sleeve through the fixed block. During the connection process, the fixed block and the connecting sleeve are threaded; therefore, during the rotation installation, the fixed block will also continuously move toward the center of the gas pipeline on the fixed sleeve until multiple fixed blocks cooperate to clamp the gas pipeline. The two gas pipelines that need to be connected will be fixed by the fixed sleeves at both ends of the connecting sleeve, and finally connected by the connecting sleeve. This connection method not only has better airtightness, but also is simple to install and easy to operate, and can dock gas pipelines of different diameters according to implementation requirements.

[0022] The fixing sleeve 1 is provided with a threaded hole 11 , and the fastener 2 is threadedly connected to the fixing sleeve 1 through the threaded hole 11 .

[0023] like Figure 2 As shown, one end of the fastener 2 is placed outside the fixing sleeve 1, and the other end of the fastener 2 is placed inside the fixing sleeve 1. The end of the fastener 2 located inside the fixing sleeve 1 is fixedly connected to the arc-shaped pressing block 13. The fastener 2 includes a threaded rod, one end of which is rotatably connected to the arc-shaped pressing plate 13, and the other end is provided with an adjusting knob. When the threaded rod is rotated by the adjusting knob, the threaded rod moves toward the axis of the fixing sleeve due to the threaded connection between the threaded rod and the fixing sleeve 1, thereby pushing the arc-shaped pressing plate 13 to clamp the gas pipeline.

[0024] Preferably, one end of the fixing sleeve 1 close to the connecting sleeve 3 is provided with connecting blocks 12 which are equidistantly distributed.

[0025] Preferably, a slide groove 42 is provided on the vertical surface of the fixing block 4 , the connecting block 12 is placed inside the slide groove 42 , and the fixing sleeve 1 is slidably connected to the fixing block 4 via the connecting block 12 .

[0026] Preferably, an external thread 41 is provided on the conical surface of the fixing block 4 , and internal threads 31 are provided at both ends of the connecting sleeve 3 . The external thread 41 is matched with the internal thread 31 , and the connecting sleeve 3 is threadedly connected to the fixing block 4 .

[0027] When the connecting sleeve 3 is sleeved on the fixing block 4 and rotated, the fixing block 4 will move toward the axial direction on the fixing sleeve 1 through the connecting block 12 until the gas pipeline is fixed.

[0028] Preferably, the connection sleeve 3 is provided with symmetrically distributed installation cavities 32 inside, and a rubber pad 33 is provided at the end of the installation cavity 32 .

[0029] The working principle of this gas pipeline connector is as follows:

[0030] When in use, the gas pipeline is initially fixed by pushing the arc-shaped pressure plate 13 through the fastener 2 on the fixing sleeve 1. The fixed fixing sleeve 1 is connected to the connecting sleeve 3 through the fixing block 4. During the connection process, the fixing block 4 is threadedly connected to the connecting sleeve 3; therefore, during the rotation installation, the fixing block 4 will also continuously move toward the center of the gas pipeline on the fixing sleeve 1 until multiple fixing blocks 4 cooperate to clamp the gas pipeline. The two gas pipelines that need to be connected will be fixed by the fixing sleeves 1 at both ends of the connecting sleeve 3, and finally connected by the connecting sleeve 3. This connection method not only has better airtightness, but also is simple to install and easy to operate, and can dock gas pipelines of different diameters according to implementation requirements.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
