Description

Wrapped type wear-resistant pipe fitting

Technical Field

The utility model belongs to the technical field of the pipeline technique and specifically relates to a wear-resisting pipe fitting of quilt package formula is related to.

Background

In the prior art, a bent pipe is generally needed for transferring in the material transferring process. However, in the pneumatic conveying system, the materials are conveyed after being fully mixed with the compressed air, and the inner side wall of the pipe is subjected to impact force. In the elbow pipe, the materials turn during the conveying process, the impact force borne by the inner wall of the elbow pipe is larger, and the elbow pipe is extremely easy to damage. At present, the bearing strength is improved by welding a covering plate on the outer side of the elbow. However, under the action of the rotational impact of the material, the covering plate is easy to fall off under the action of the impact, or the two sides of the covering plate are damaged before the position of the covering plate, so that the service life is short.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a by wear-resisting pipe fitting of package formula, simple structure, effectual bearing strength, joint strength have been improved, have prolonged life.

In order to achieve the above object, the utility model provides a by wear-resisting pipe fitting of package formula, including the return bend body, the return bend body includes ceramic layer, metal level and the overburden that sets gradually from inside to outside, the overburden is by the center to the thickness structure that dwindles gradually all around, the metal level includes the straight pipeline at both ends and is located the arc pipeline that a plurality of links to each other between the straight pipeline, straight pipeline with be connected at a distance from between the panel interface of arc pipeline, all be in on the same horizontal curve between the interface in the inboard and the outside of return bend body.

Preferably, the inner side of the covering layer is provided with a limiting concave matched with the limiting convex on the outer side of the metal layer.

Preferably, the two side ends of the straight pipeline are respectively provided with a female connector, and the surface of the ceramic layer and the inner side of the female connector are positioned in the same plane.

Preferably, the straight pipeline and the arc pipeline are formed by bending and welding metal plates.

Preferably, a connecting hook is arranged on the straight pipeline or the arc pipeline of the elbow body, wherein the interface of the elbow body is positioned at the outer side of the straight pipeline or the arc pipeline.

Therefore, the utility model adopts the above-mentioned wear-resisting pipe fitting of quilt package formula, simple structure, effectual bearing strength, joint strength have been improved, have prolonged life.

The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

1. A bent pipe body; 2. a ceramic layer; 3. a metal layer; 4. a cover layer; 5. an interface; 6. a straight pipeline; 7. an arc-shaped pipeline; 8. a limiting protrusion; 9. a female connection port; 10. and (4) connecting hooks.

Detailed Description

The technical solution of the present invention is further explained by the accompanying drawings and examples.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

As shown in the figure, a by wear-resisting pipe fitting of package formula, including return bend body 1, return bend body 1 includes ceramic layer 2, metal level 3 and the overburden 4 that sets gradually from inside to outside, sets up the wear resistance who improves return bend body 1 through the structure of three-layer. The covering layer 4 is a structure with the thickness gradually reduced from the center to the periphery, so that the bearing strength of the elbow pipe body 1 can be gradually improved from the outside to the inside, and the situation that the local bearing strength is suddenly improved to cause large peripheral stress can not occur. The inboard of overburden 4 is equipped with the spacing concave that matches with the spacing protruding 8 in metal level 3 outside, realizes overburden 4 stable connection in metal level 3 through spacing concave and spacing protruding 8, improves the compactness of the two connections.

The metal level 3 includes the straight tube way 6 at both ends and is located the arc pipeline 7 that a plurality of links to each other between the straight tube way 6, and the both sides tip of straight tube way 6 all is equipped with female connector 9 for with being connected of both sides pipeline. The surface of the ceramic layer 2 and the inner side of the female connector 9 are positioned in the same plane, so that the stable arrangement of the ceramic layer 2 is ensured, and the rapid transportation of materials cannot be blocked.

The straight pipeline 6 and the arc pipeline 7 are formed by bending and welding metal plates, and the interface 5 of the metal plates is welded to form the straight pipeline 6 or the arc pipeline 7. The straight pipeline 6 is connected with the plate connector 5 of the arc pipeline 7 at intervals, so that the bearing strength of the elbow body 1 is improved, the connectors 5 are prevented from being located on the same side, the bearing strength is reduced, and the service life is shortened. The interfaces 5 on the inner side and the outer side of the elbow body 1 are positioned on the same horizontal curve, so that the bearing strength of the elbow is improved. The straight pipeline 6 or the arc pipeline 7 of which the upper interface 5 of the elbow body 1 is positioned at the outer side is provided with a connecting hook 10, and the position of the connecting hook 10 is provided with a stable connection which ensures the connecting hook 10.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
