Description

Technical Field

[0001] The utility model relates to the technical field of rubber gaskets, and more specifically, to a rubber gasket for pipelines. Background Art

[0002] During the use of pipelines, in order to ensure the sealing performance during pipeline use, rubber gaskets are usually arranged at the joints of pipelines to improve the sealing effect of the pipelines.

[0003] Existing rubber gaskets for pipelines are installed in the sealing grooves on the pipelines during installation. However, when the inner side walls of the sealing grooves are irregular, gaps are likely to occur between the side walls of the rubber gaskets and the side walls of the sealing grooves, resulting in a significant reduction in the sealing effect. Moreover, after the existing rubber gaskets for pipelines are installed in the sealing grooves for a long time, the rubber gaskets are easily stuck in the sealing grooves, making the subsequent disassembly and replacement work extremely troublesome.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] As shown in the attached Figures 1-4 A rubber gasket for a pipeline, comprising: two semi-circular rubber rings 1, the two semi-circular rubber rings 1 form an entire ring, and a disassembly and assembly mechanism 2 for disassembling and assembling the two semi-circular rubber rings 1 is provided on one side where the two semi-circular rubber rings 1 are close to each other. Two air cylinders 3 are respectively embedded and fixedly connected in the two semi-circular rubber rings 1. An inflation mechanism 4 for improving the sealing effect of the semi-circular rubber ring 1 is provided in both of the two air cylinders 3. Both of the two semi-circular rubber rings 1 are made of rubber material.

[0021] The inflation mechanism 4 includes an arc-shaped rack 5 provided in the air cylinder 3. A storage groove 6 is opened in the semi-circular rubber ring 1 at a position opposite to the arc-shaped rack 5. One end of the arc-shaped rack 5 penetrates the side wall of the air cylinder 3 and is slidably connected to the inner side wall of the storage groove 6. A rotation groove 8 is opened on one side of the storage groove 6 at a position opposite to the arc-shaped rack 5. A gear column 7 is rotatably connected in the rotation groove 8. The gear column 7 is meshed with one side of the arc-shaped rack 5. A piston 9 is fixedly connected to one end of the arc-shaped rack 5 located in the air cylinder 3. An airbag 12 is opened in the semi-circular rubber ring 1. An air outlet 10 is opened at one end of the air cylinder 3 away from the storage groove 6. An air inlet 11 is opened on one side of the airbag 12 close to the air outlet 10. The air outlet 10 is communicated with the air inlet 11. The air in the air cylinder 3 enters the airbag 12 through the movement of the piston 9, causing the entire semi-circular rubber ring 1 to expand and improving its sealing effect.

[0022] A rubber ring 13 is fixedly connected to the outer side wall of the piston 9. The side wall of the rubber ring 13 is slidably connected to the inner side wall of the air cylinder 3. The airtightness of the piston 9 is improved through the rubber ring 13.

[0023] A hexagonal screw rod 14 is vertically and fixedly connected to the top end of the gear column 7. The top end of the hexagonal screw rod 14 penetrates the side wall of the semi-circular rubber ring 1 and extends to the outside of the semi-circular rubber ring 1. The hexagonal screw rod 14 is threadedly connected to the semi-circular rubber ring 1. By threadedly connecting the hexagonal screw rod 14 to the semi-circular rubber ring 1, the rotation of the gear column 7 can be avoided, improving the stability of the inflation process.

[0024] The specific implementation method is as follows: By setting the inflation mechanism 4, it is convenient to make the semi-circular rubber ring 1 expand, so that it is in close contact with the inner side wall of the sealing groove, greatly improving its sealing effect.

[0025] As shown in the attached Figures 1-3A rubber gasket for a pipeline as shown. The disassembly and assembly mechanism 2 includes a first extension portion 15 fixedly connected to one end of two semi-circular rubber rings 1. Two second extension portions 16 are respectively fixedly connected to the other end of the two semi-circular rubber rings 1 and are matched with the first extension portion 15. The first extension portion 15 and the second extension portion 16 are both of an integral structure with the semi-circular rubber ring 1. The side walls of the two first extension portions 15 are in contact connection with the side walls of the corresponding second extension portions 16.

[0026] Two through holes 17 are respectively formed through the top surfaces of the two semi-circular rubber rings 1 above the hexagonal screw 14, facilitating the driving of the hexagonal screw 14 through the two through holes 17.

[0027] The specific implementation manner is as follows: By providing the disassembly and assembly mechanism 2, it is convenient to disassemble and assemble the two semi-circular rubber rings 1, greatly improving the convenience of later disassembly and replacement.

[0028] The working principle of the present utility model: During use, the two semi-circular rubber rings 1 are both placed in the sealing groove of the pipeline, and the first extension portion 15 and the second extension portion 16 on the two semi-circular rubber rings 1 are made to match. Then, the two hexagonal screws 14 are rotated. The hexagonal screws 14 drive the gear columns 7 to rotate, causing the corresponding arc-shaped racks 5 to slide into the air cylinder 3 from the storage groove 6 and pushing the piston 9 to slide forward. The air in the air cylinder 3 is pushed into the airbag 12 through the air outlet 10 and the air inlet 11, causing the whole semi-circular rubber ring 1 to expand. At this time, the side wall of the semi-circular rubber ring 1 can be in close contact connection with the inner side wall of the sealing groove of the pipeline, greatly improving its sealing effect; when it is necessary to disassemble the rubber gasket, by overlapping the first extension portion 15 and the second extension portion 16, it is convenient to disassemble between the two semi-circular rubber rings 1, greatly improving the convenience of disassembling the two semi-circular rubber rings 1 and facilitating the later disassembly and replacement operation of the rubber gasket.
