Description

A rubber sealing ring

Technical field

The utility model relates to the technical field of water pipe docking, specifically to a rubber sealing ring.

Background technique

Water pipes are water supply pipes. There are three types of water pipes. The first category is metal pipes, such as hot-dip cast iron pipes, copper pipes, stainless steel pipes, etc. with plastic lining inside. The second category is plastic-clad metal pipes, such as steel-plastic composite pipes, aluminum-plastic composite pipes, etc. The third category is plastic pipes, such as PB pipes, PP-R pipes, etc.

When laying water supply pipelines, multiple pipelines need to be connected in sequence. Adjacent water pipes are connected through hoops. A sealing ring is installed at the connection between the hoop and adjacent water pipes to enhance sealing and prevent leakage of water supply. . Figure 1 of the description is a schematic structural diagram of an existing sealing ring, through which leakage between adjacent water pipe gaps and hoops is blocked. Since the sealing ring is only used to cover the above-mentioned gap, the adjacent water pipes are in hard contact and there is a gap during the docking. When the water pressure is high, the water pressure frequently impacts the sealing ring. The above-mentioned gap is prone to leakage, resulting in poor waterproof sealing. The problem.

Detailed ways

Example

Referring to Figures 2-4, a rubber sealing ring includes an annular rubber ring 1 with elastic deformation function. A first annular rubber part 2 is provided at the inner middle position of the annular rubber ring 1;

The first annular rubber part 2 is arranged along the circumferential direction of the annular rubber ring 1, and the first annular rubber part 2 is capable of elastic deformation.

This new type of use is applied when two water pipes are butted together. The annular rubber ring 1 is placed at the joint of the two water pipes, and the first annular rubber piece 2 is inserted between the butt surfaces of the two water pipes. Finally, the annular rubber ring is carried out through the hoop. The locking of ring 1 achieves the butt sealing of the two water pipes. In the present utility model, the first annular rubber part 2 with elastic function realizes the soft contact between the two water pipes (the docking between the hard water pipe and the elastic structure). The first annular rubber part 2 will be filled due to its elastic function. The unevenness of the end face of the water pipe prevents gaps between the two water pipes, and the sealing effect is better. Even if the water pressure is high, there is no problem of water flowing out of the gap.

Traditional water pipes are hard water pipes. The end faces of water pipes cannot be absolutely flat. The butt joint between two hard water pipes is a hard contact fit. When two uneven hard water pipes are butted together, there will be a gap, and water leakage will occur in the gap. When the water pressure is high, the sealing ring is prone to leakage.

In some embodiments of the present invention, second annular rubber parts 3 are provided at both ends of the inner side of the annular rubber ring 1, and the second annular rubber parts 3 are provided along the circumferential direction of the annular rubber ring 1;

The inner side of the second annular rubber member 3 is inclined toward the middle of the annular rubber ring 1 . A buffer area is formed at intervals between an end of the second annular rubber member 3 away from the annular rubber ring 1 and the annular rubber ring 1 .

In the above embodiment, when the hoop presses the annular rubber ring 1 at the connection of the two water pipes, the second annular rubber member 3 has elasticity and has a tendency to move toward the side away from the hoop, causing the second annular rubber member 3 to move away from the hoop. Part 3 is close to the water pipe to improve sealing.

If the water pipe connection leaks into the buffer area, the water pressure has a pressure effect on the second annular rubber part 3, which further makes the second annular rubber part 3 close to the water pipe, helping to prevent leakage.

In some embodiments of the present invention, the above-mentioned annular rubber ring 1, the above-mentioned first annular rubber part 2 and the above-mentioned second annular rubber part 3 are all made of the same material;

The above-mentioned annular rubber ring 1, the above-mentioned first annular rubber part 2 and the above-mentioned second annular rubber part 3 are formed into an integrally formed structure.

In the above embodiment, the above-mentioned annular rubber ring 1, the above-mentioned first annular rubber part 2 and the above-mentioned second annular rubber part 3 are all made of elastic rubber. The annular rubber ring 1, the first annular rubber part 2 and the second annular rubber part 3 are formed into a one-piece structure, which improves the stability of the overall structure of the utility model and is beneficial to increasing the practical life of the utility model.

In some embodiments of the present invention, the first annular rubber part 2 includes a first annular part 201 connected to the annular rubber ring 1, and a second annular part 202 is connected to the middle part of the inner side of the first annular part 201;

The cross-sectional area of the first annular portion 201 is larger than the cross-sectional area of the second annular portion 202 .

In the above embodiment, the second annular portion 202 is used to be inserted into the joint surface of two water pipes to enhance the sealing; the first annular portion 201 is located outside the joint of the water pipes, and the first annular portion 201 is held by the hoop at the same time. Pressing on the two water pipes and the second annular part 202 strengthens the sealing between the water pipes and the second annular part 202, further improving the sealing performance.

In some embodiments of the present invention, the first annular portion 201 and the second annular portion 202 are formed into an integral structure.

In the above embodiment, the integrally formed first annular part 201 and the second annular part 202 make the structure of the first annular rubber part 2 more stable and help improve the service life of the first annular rubber part 2 .

In some embodiments of the present invention, both sides of the second annular portion 202 in the axial direction are parallel.

In the above embodiment, both sides of the second annular part 202 are parallel surfaces, that is, the side surfaces of the second annular part 202 are in the radial direction of the annular rubber ring 1; in actual use, the surface of the second annular part 202 and the side surface of the water pipe Parallel, when the two fit together, the force on each part will be more even.

The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
