Description

Technical Field

[0001] The utility model relates to the technical field of sealing elements, and in particular to a sealing element based on compression of asbestos-free fiber rubber. Background Art

[0002] Seals are materials or parts that prevent fluids or solid particles from leaking between adjacent joint surfaces and prevent external impurities such as dust and moisture from invading parts inside machinery and equipment. The best storage room temperature for seals is below 30°C to avoid high-temperature aging of the seals. The connection of multiple sets of pipes requires the use of specific connection components, and seals are provided inside the connection components. On the one hand, the seals can increase the friction between the pipes and the connection components, thereby fixing the pipes inside the connection components. At the same time, the seals have the effect of waterproofing. In the past, seals were mostly made of rubber materials containing asbestos fibers, which had a high hardness and were easily deformed or even broken after long-term use, thus affecting the sealing of the connection between the connection components and the pipes.

[0003] On the one hand, pipes exposed to the outside are easily eroded by rainwater, and on the other hand, they are easily impacted by the outside world, which can easily lead to damage to the exposed pipes. The degree of damage to each part of the pipe is different, and the maintenance cost of replacing the entire set of pipes is relatively high. Therefore, the pipes at the damaged position are usually cut off, and pipe connection components and seals are added at the cutoff of the pipe to maintain the normal use of the pipe. However, since the length of the pipe cutoff cannot be estimated, the length of the added pipe connection components needs to be customized. On the one hand, the pipe connection components are not easy to install, and on the other hand, the length of the pipe connection components is not easy to adjust. For this reason, a seal based on asbestos-free fiber rubber compression is proposed, which solves the above problems through a connecting pipe with adjustable length, a left clamping column and a right clamping column. Utility Model Content

[0004] The utility model provides a sealing component based on compression of asbestos-free fiber rubber, which solves the problem that the length of a pipeline connection component is not easy to be freely adjusted according to the cut-off length of the pipeline.

[0006] A sealing member based on asbestos-free fiber rubber compression comprises a connecting tube, one side of the connecting tube is slidably connected to a left-side clamping column, the other side of the connecting tube is slidably connected to a right-side clamping column, the interiors of the left-side clamping column and the right-side clamping column are fixedly connected to a resist column, a clamping groove is provided between the left-side clamping column and the resist column, and between the right-side clamping column and the resist column, a fixing rod is clamped between the left-side clamping column and the right-side clamping column, and the outer end of the fixing rod is threadedly connected to a fixing nut.

[0007] Preferably, the fixing rods are provided in four groups, the four groups of fixing rods are arranged in an X shape, and the fixing nuts are provided in two groups, and the two fixing nuts are respectively arranged on both sides of the right clamping column.

[0008] Preferably, the inner diameters of the left clamping column and the right clamping column are the same, the outer ends of the left clamping column and the right clamping column are fixedly connected with claws, and the outer ends of the claws are threadedly connected with a fastening ring.

[0009] Preferably, the caliber of the connecting pipe is smaller than the calibers of the left clamping column and the right clamping column, a sealing ring is provided on the side sleeve of the connecting pipe, and the inner walls of the left clamping column and the right clamping column are fixedly connected to a limiting rod.

[0010] Preferably, the limiting rods are provided with four ring-shaped and equidistantly arranged, the outer end of the sealing ring is provided with a groove, and the limiting rods are arranged inside the groove.

[0012] The working principle and beneficial effects of the utility model are:

[0013] 1. In the utility model, the left clamping column and the right clamping column are respectively clamped to the two ports at the cutoff point of the pipeline, and the clamping grooves between the left clamping column, the right clamping column and the internal fixed abutment column clamp the pipeline from the inside and outside of the pipeline.

DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1~Figure 3 As shown, a sealing component based on asbestos-free fiber rubber compression includes a connecting tube 1, one side of the connecting tube 1 is slidably connected with a left-side clamping column 2, the other side of the connecting tube 1 is slidably connected with a right-side clamping column 3, the insides of the left-side clamping column 2 and the right-side clamping column 3 are fixedly connected with a resisting column 4, and a clamping groove 5 is provided between the left-side clamping column 2 and the resisting column 4 as well as between the right-side clamping column 3 and the resisting column 4, a fixing rod 7 is clamped between the left-side clamping column 2 and the right-side clamping column 3, and the outer end of the fixing rod 7 is threadedly connected with a fixing nut 8. The purpose of this arrangement is that the left-side clamping column 2 and the right-side clamping column 3 are used to connect the cut-off part of the pipe. The left-side clamping column 2, the right-side clamping column 3 and the clamping groove 5 between the inner and outer sides of the pipe port position are clamped at the same time. On the one hand, the stability of the connection between the pipe and the left-side clamping column 2 and the right-side clamping column 3 is enhanced. On the other hand, it is convenient for installation and enhances the sealing of the connection between the pipe and the left-side clamping column 2 and the right-side clamping column 3. The fixed rod 7 and the two fixing nuts 8 at its outer ends can fix the distance between the left-side clamping column 2 and the right-side clamping column 3 to prevent the connection between the left-side clamping column 2, the right-side clamping column 3 and the cut-off part of the pipe from loosening.

[0024] Preferably, there are four groups of fixing rods 7, which are arranged in an X shape, and two fixing nuts 8 are provided, which are respectively arranged on both sides of the right clamping column 3. The purpose of this arrangement is that the four groups of fixing rods 7 arranged in an X shape enhance the stability of the left clamping column 2 and the right clamping column 3, and the fixing rods 7 are arranged at the outer end of the connecting pipe 1 for easy operation. At the same time, the external fixing rods 7 and the fixing nuts 8 are used to connect the left clamping column 2 and the right clamping column 3. When the connection between the fixing rods 7 and the fixing nuts 8 is corroded, the left clamping column 2 and the right clamping column 3 can also be disassembled by cutting off the fixing rods 7.

[0025] Preferably, the inner diameters of the left clamping column 2 and the right clamping column 3 are the same, and the outer ends of the left clamping column 2 and the right clamping column 3 are fixedly connected with claws 6, and the outer ends of the claws 6 are threadedly connected with fastening rings 9. The purpose of this arrangement is that the provided claws 6 and fastening rings 9 can fix the left clamping column 2 and the right clamping column 3 from the outside of the pipeline, and the fixing method is simple and easy to operate.

[0026] In this embodiment, at the cutoff point of the pipeline, the left-side clamping column 2 is first clamped to one side port of the pipeline cutoff point, and the fastening ring 9 is rotated to fix it. Then, according to the length of the pipeline cutoff, the right-side clamping column 3 is pulled, and the right-side clamping column 3 is clamped to the other side port of the pipeline cutoff point. The connecting pipe 1, the left-side clamping column 2 and the right-side clamping column 3 are connected in a sliding manner, so that it is convenient to adjust it according to the length of the pipeline cutoff. It is applicable to many scenarios. After the left-side clamping column 2 and the right-side clamping column 3 are fixed, four sets of fixing rods 7 are connected between the left-side clamping column 2 and the right-side clamping column 3, and two fixing nuts 8 are used to fix them from both sides of the right-side clamping column 3 to prevent the left-side clamping column 2, the right-side clamping column 3 from loosening at the connection with the port of the pipeline.

[0027] Example 2

[0028] like Figure 1~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the diameter of the connecting pipe 1 is smaller than the diameters of the left clamping column 2 and the right clamping column 3, the side sleeve of the connecting pipe 1 is provided with a sealing ring 10, and the inner walls of the left clamping column 2 and the right clamping column 3 are fixedly connected with a limit rod 11. The purpose of this arrangement is that the provided sealing ring 10 enhances the sealing between the left clamping column 2, the right clamping column 3 and the connecting pipe 1 to prevent leakage at the connection.

[0029] Preferably, four limiting rods 11 are arranged in an annular shape and at equal distances, and a groove is provided at the outer end of the sealing ring 10, and the limiting rod 11 is arranged inside the groove. The purpose of this arrangement is that the limiting rod 11 prevents the connecting pipe 1 from rotating inside the left clamping column 2 and the right clamping column 3, thereby reducing the edge wear of the connecting pipe 1, which leads to leakage and seepage at the large connection of the pipeline.

[0030] Preferably, the inner walls of the left clamping column 2 and the right clamping column 3 are provided with a connecting groove 12, the connecting groove 12 is in communication with the clamping groove 5, a gasket 13 is clamped inside the connecting groove 12, a spring 14 is provided inside the connecting groove 12, and the spring 14 is fixedly connected between the left clamping column 2, the right clamping column 3 and the gasket 13. The purpose of this arrangement is that the spring 14 makes the gasket 13 spring outward, while increasing the friction between the gasket 13 and the pipeline, enhancing the sealing of the connection between the pipeline and the left clamping column 2 and the right clamping column 3.

[0031] In this embodiment, after the pipe is inserted into the slot 5 inside the left clamping column 2 and the right clamping column 3, the elastic force generated by the spring 14 makes the inner wall of the gasket 13 always fit with the outer wall of the pipe, increasing the friction between the gasket 13 and the pipe, thereby preventing the connection between the pipe and the left clamping column 2 and the right clamping column 3 from loosening. At the same time, the gasket 13 enhances the sealing of the connection between the pipe and the left clamping column 2 and the right clamping column 3, preventing leakage and seepage at the connection between the pipe and the left clamping column 2 and the right clamping column 3.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
