The utility model provides a following technical scheme: a wear-resistant elbow comprises an elbow main body, an anti-corrosion inner layer and an anti-corrosion outer layer, wherein the anti-corrosion inner layer is arranged on the inner side of the elbow main body, the anti-corrosion outer layer is arranged on the outer side of the elbow main body, flange plates are welded on the outer sides of two sides of a port of the elbow main body, and an inner rubber ring and an outer rubber ring are respectively embedded on the surfaces of the flange plates;
further, the anti-corrosion inner layer is made of wear-resistant steel materials;
further, the anti-corrosion outer layer is a ceramic-resistant material;
further, the anti-corrosion inner layer is arranged on the inner side close to the two sides of the port of the elbow main body;
furthermore, the anticorrosion inner layer is arranged at the inner sides close to the two sides of the port of the elbow main body;
further, the anti-corrosion outer layer is arranged on the outer side of the bent part of the elbow main body;
further, the wear-resistant steel material is attached to the outer side of the bent part of the elbow main body in a welding mode;
furthermore, the ceramic-resistant material is deposited on the inner sides of the two sides of the port of the elbow main body in an electroless plating mode.
Compared with the prior art, the utility model discloses possess following beneficial effect:
1) the utility model discloses wear-resisting elbow adopts the anticorrosion inlayer and the outer wear-resisting elbow life that improves of anticorrosion and avoids elbow department wearing and tearing to lead to the hole.
2) The utility model discloses wear-resisting elbow simple structure is convenient for dismouting and batch production.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. In the drawings in the embodiments of the present invention, different kinds of section lines are not labeled according to national standards, and do not require the material of the element, and the section lines of the element in the drawings are distinguished.
Please refer to fig. 1, fig. 1 is a side view of the wear-resistant elbow of the present invention, which has the following technical features, an elbow main body, an anti-corrosion inner layer 1c, an anti-corrosion outer layer 1b, an anti-corrosion inner layer 1c and an anti-corrosion outer layer 1b are disposed on the inner side of the elbow main body, a flange plate 1a is welded on the outer side of the two sides of the port of the elbow main body, the flange plate 1a is disposed in 2 numbers, the flange plate 1a is disposed at the two ends of the elbow main body, the end surface of the flange plate 1a is flush with the end surface of the elbow main body, and the design of the above structure ensures the sealing performance when the flanges are connected. Wherein, the anti-corrosion inner layer 1c is made of wear-resistant steel material, and the anti-corrosion outer layer 1b is made of ceramic-resistant material; the anti-corrosion inner layer 1c is arranged at the inner side close to the two sides of the port of the elbow main body; the anti-corrosion outer layer 1b is arranged on the outer side of the bending part of the elbow main body; the wear-resistant steel material is attached to the outer side of the bent part of the elbow main body in a welding mode; and the ceramic-resistant material is deposited on the inner sides of the two sides of the port of the elbow main body in an electroless plating mode.
Please refer to fig. 2, fig. 2 is the utility model discloses wear-resisting elbow top view, the surface of ring flange 2a is inlayed respectively and is had interior rubber circle and outer rubber circle (not shown), the thickness of interior rubber circle equals the thickness of outer rubber circle, and the central line of interior rubber circle coincides each other with the central line of outer rubber circle, and the inside of outer rubber circle is arranged in to interior rubber circle, the terminal surface of both terminal surfaces equal protrusion ring flanges of interior rubber circle and outer rubber circle simultaneously, the design of above-mentioned structure, through the characteristic of rubber flexible deformation, the use of interior rubber circle and outer rubber circle is being cooperated, very big increase the leakproofness between flange and the flange. The surface of the flange 2a is also provided with a deformation device 2c, and when the connection is needed, the deformation device 2c is adopted for expansion and contraction to connect with the opposite pipeline.
The working principle is as follows: when the wear-resistant elbow is used, firstly, in the using process, as shown in figures 1-2, a flange plate on the outer side of the elbow main body is connected with a facing pipeline in a flange mode, meanwhile, the sealing performance of the flange connection part is improved through the inner rubber ring and the outer rubber ring, and the sealing performance and the practicability are further improved through the deformation device.
