Description

Wear-resistant elbow

Technical Field

The utility model relates to an electric power production equipment technical field especially relates to a wear-resisting elbow.

Background

In the power production, the medium needs to be conveyed in the pipeline, the wear-resistant elbow needs to be arranged at the corner of the pipeline output, the existing wear-resistant elbow is not a wear-resistant material, and the length of the straight pipe section is not enough, so that the straight pipe section at the joint of the wear-resistant elbow is easily worn, the medium leakage is caused, the environment is polluted, and the maintenance workload is increased.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a wear-resistant elbow, aiming at the technical defects, the expansion wear-resistant pipe section arranged at one side of the outlet of the elbow is adopted, thereby realizing the function of avoiding the abrasion of the pipeline when the dust airflow just flows through the outlet of the elbow, solving the problems of medium leakage, environmental pollution and increased maintenance workload; the adoption will expand the setting that equals with elbow body internal diameter behind the wear-resisting layer of wear-resisting pipe section inner wall laminating, has realized avoiding the dust air current can form swirl air current in inside to the problem of increase wearing and tearing has further been solved because the medium leaks, the polluted environment, and the problem of increase maintenance work load.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: comprises an elbow body, an elbow inlet, an elbow outlet and a wear-resistant layer; an elbow inlet is formed in one end of the elbow body; an elbow outlet is formed in one side, away from the elbow inlet, of the elbow body; a bent part is arranged between the elbow inlet and the elbow outlet; the outlet of the elbow is provided with an expanded wear-resistant pipe section along the tangential direction; and a wear-resistant layer is arranged in the expansion wear-resistant pipe section.

Further optimizing the technical scheme, the inner wall of the expanded wear-resistant pipe section is attached with the wear-resistant layer and then is equal to the inner diameter of the elbow body.

Further optimizing the technical scheme, the length of the expansion wear-resistant pipe section is 500 mm.

Further optimizing the technical scheme, the inner wall of the expansion wear-resistant pipe section and the wear-resistant layer are glued.

Compared with the prior art, the utility model has the advantages of it is following: 1. the structure is favorable for ensuring the function of avoiding the abrasion of the pipeline when the dust airflow just flows through the outlet of the elbow; 2. the arrangement that the inner diameter of the inner wall of the expanded wear-resistant pipe section is equal to the inner diameter of the elbow body after being attached to the wear-resistant layer ensures that the structure is favorable for avoiding the dust airflow from forming vortex airflow in the elbow body, thereby increasing the wear problem.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: shown in a combined figure 1-2, comprises an elbow body 1, an elbow inlet 2, an elbow outlet 3 and a wear-resistant layer 4; an elbow inlet 2 is arranged at one end of the elbow body 1; an elbow outlet 3 is arranged on one side of the elbow body 1, which is far away from the elbow inlet 2; a bent part 6 is arranged between the elbow inlet 2 and the elbow outlet 3; the elbow outlet 3 is provided with an expanded wear-resistant pipe section 5 along the tangential direction; a wear-resistant layer 4 is arranged in the expansion wear-resistant pipe section 5; the inner wall of the expansion wear-resistant pipe section 5 is attached with the wear-resistant layer 4 and then is equal to the inner diameter of the elbow body 1; the length of the expansion wear-resistant pipe section 5 is 500 mm; the inner wall of the expansion wear-resistant pipe section 5 and the wear-resistant layer 4 are glued.

When in use, as shown in the figure 1-2, when the dust airflow is introduced into the elbow pipe, the expansion wear-resistant pipe section 5 arranged on one side of the elbow outlet 3 is adopted, so that the dust airflow enters from the elbow inlet 2, the airflow direction changes at the elbow part 6, and then flows from the elbow outlet 3 to the expansion wear-resistant pipe section 5, the airflow direction of the dust flowing out from the elbow part 6 is not completely changed, the airflow direction does not change immediately when flowing out from the elbow outlet 3, and the dust impacts the inner wall of the elbow pipe, so that the service life of the elbow is seriously reduced, because the expansion wear-resistant pipe section is arranged, the wear-resistant layer 4 is arranged on the inner wall of the expansion wear-resistant pipe section 5, so that the dust flowing out originally can not directly impact the inner wall of the elbow, the wear-resistant layer 4 with a certain length is arranged, the dust airflow in the elbow can be enabled to flow in the pipe after completely changing, the problem of avoiding the dust air current can form swirl air current in inside to increase wearing and tearing has been guaranteed.

The utility model discloses a control mode comes automatic control through the controller, and the control circuit of controller can realize through the simple programming of technical staff in this field, belongs to the common general knowledge in this field, and the utility model discloses mainly be used for protecting the machinery setting, so the utility model discloses no longer explain control mode and circuit connection in detail.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention.
