AI Technical Summary
When existing rubber elbows convey fluid with high friction, long-term impact will aggravate the wear of the rubber elbow pipe wall and seriously affect the service life.
A rubber elbow lined with a ceramic layer is designed. By setting up a ceramic layer on the inner wall of the rubber elbow, and setting up a reinforcement layer and a retaining ring on the outside, the impact resistance and wear resistance of the elbow are enhanced.
Through the arrangement of the ceramic layer, the impact resistance and wear resistance of the rubber elbow are increased, which extends the service life, while the reinforcement layer increases the overall strength of the elbow.

[0006] Preferably, the ceramic layer is composed of a plurality of square ceramic sheets or circular ceramic sheets or ceramic columns.
[0007] Preferably, the ceramic layer and the rubber body are fixed by a vulcanization process.
[0008] Preferably, the reinforcement layer is woven from metal wires or non-metal wires.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] 1. Increase the strength of the rubber elbow by setting a reinforcement layer;
[0011] 2. By setting the ceramic layer, the impact resistance and wear resistance of the inner wall are increased, and the service life is extended;
[0012] 3. The retaining rings and flanges at both ends of the rubber elbow are convenient for connecting with the rubber tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in 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 in 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.
[0018] Example 1: Please refer to Figure 1-3 A rubber elbow lined with a ceramic layer comprises a rubber elbow 1, a retaining ring 2, a flange 3, a rubber body 4, a reinforcing layer 5 and a ceramic layer 6, wherein retaining rings 2 are respectively provided at both ends of the rubber elbow 1, two flanges are sleeved at the rubber elbow 1 between the retaining rings 2, and the retaining ring 2 can block the flange, the rubber elbow 1 is composed of a rubber body 4, a reinforcing layer 5 and a ceramic layer 6, a reinforcing layer 5 is provided at the center of the rubber body 4, and a ceramic layer 6 is provided on the inner wall of the rubber body 4.
[0019] The ceramic layer 6 can be made of alumina ceramic material, and is composed of a number of evenly arranged square ceramic sheets, circular ceramic sheets or other polygonal ceramic sheets and ceramic columns, with a diameter of 3-4 mm and a thickness of 2-4 mm. The specific size is determined by the size of the rubber elbow.
[0020] The ceramic layer 6 and the rubber body 4 are fixed by a vulcanization process.
[0021] The reinforcing layer 5 is woven from metal wires or non-metal wires. The metal wires are currently made of thin steel wires, and the non-metal wires are currently made of nylon wires. The reinforcing layer is used to enhance the strength of the rubber elbow so that it is not easily deformed.
