Disclosure of Invention

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

sealing rubber circle that possesses sealing tooth includes:

the sealing part is positioned at the inner side, a wavy tooth part is arranged at the position, adjacent to the hole wall, of the sealing part, and the tooth part forms a redundant structure when the pipe fitting is inserted into the rubber ring, so that the rubber ring is adapted to the pipe fitting within a certain range;

the outer side of the sealing part is also provided with a reducing part, and the reducing part is provided with a reducing surface matched with the joint, so that the rubber ring is tightly attached to the pipe fitting to seal when being extruded by the joint.

In a preferred embodiment of the utility model, the teeth are formed by laterally staggered teeth forming a contact seal for small diameter pipe elements and teeth forming a contact seal for large diameter pipe elements.

In a preferred embodiment of the present utility model, the vertical dimension of the male teeth and/or the female teeth is 0.2 inches.

In a preferred embodiment of the present utility model, the reducing surface is connected to an upper end of the reducing portion and is connected to an edge of the sealing portion by a linear slope structure.

In a preferred embodiment of the utility model, the tapered surface is 30 °, the seal portion has a thickness of 0.36 inches and the tapered portion has a thickness of 0.72 inches.

In a preferred embodiment of the present utility model, the sealing portion and the reducing portion are made of FPM.

The utility model has the beneficial effects that:

according to the sealing rubber ring with the sealing teeth, the reducing surface matched with the joint is arranged on the outer side of the sealing rubber ring to assist the reducing shrinkage of the sealing ring, and the concave-convex tooth parts are arranged on the inner surface of the sealing ring to enable the sealing ring to adapt to pipe fittings with different outer diameter sizes, so that the purpose of sealing can be achieved in a clinging mode.

Throughout the drawings, like reference numbers indicate identical or functionally identical elements.

Fig. 1 shows the application of the utility model in a sealing joint by placing a sealing ring 5 in a reducing ring 3 with a gradually decreasing inner diameter, and applying pressure to the sealing ring 5 from one side by means of a fastener 4 in cooperation with a gland 1 to clamp a pipe 6.

Fig. 2 and 3 show a specific structure of the seal ring 5, in which the body 5 is annular so as to seal around the outer periphery of the tube 6, and the body 5 is constituted by an inner seal portion 57 and an outer diameter-changing portion 53. The reducing portion 53 has a reducing surface 54 connecting an upper end 55 thereof with a lower end 56 located at a junction of the sealing portion 57, and the reducing surface 54 is a linear inclined surface. The body 5 is pressed, contracted and deformed by the connection of the reducing surface 54 with the reducing ring 3. Teeth 58 are provided at the location where the seal 57 borders the bore wall 52 to accommodate pipes 6 of different outer diameters. Teeth 58 include staggered and laterally equally sized male and female teeth 58b, 58a to accommodate different outer diameter tubes by utilizing the dimensional differences formed by male and female teeth 58b, 58 a.

In one embodiment of the present utility model, the lateral dimensions of the male teeth 58b and/or female teeth 58a are 0.06 inches, respectively, with the maximum outer diameter of the bore wall 52 being 9.55 inches and the minimum outer diameter being 9.35 inches (i.e., the vertical dimension of the male teeth 58b and/or female teeth 58a being 0.2 inches). Such that the seal ring 5 seals with the teeth 58b when 9.46 inches of pipe is inserted and seals with the teeth 58a and/or deformed teeth 58 when 9.85 inches of pipe is inserted.

In one embodiment of the present utility model, the tapered surface is inclined at an angle of 30 °, the thickness of the seal 37 is 0.36 inches, and the thickness of the tapered portion 53 is 0.72 inches. The body 51 is less likely to be damaged during extrusion at this dimensional ratio.
