Description
Technical Field
The utility model relates to a wear-resisting return bend, in particular to wear-resisting return bend of positive hexagonal arc antifriction plate of inside lining.
Background
In modern industrial production, the transportation of many materials is involved, and pipelines are mostly used for transporting materials. The pipeline is abraded inevitably due to the flowing of materials, the abrasion of different materials to the pipeline under different working conditions is different, the pipeline is worn out in time, the materials are leaked, and the economic loss of enterprises and the environment around the pipeline are polluted. In the same pipe system, because the pipe inflection point is most impacted by the material, the pipe inflection point (i.e. the bend) is generally worn first. Therefore, how to effectively solve the problem of pipe abrasion, especially the abrasion of the elbow, is an important problem in industrial production. Aiming at the situation, various enterprises invent various methods to solve the problem, such as a wear-resistant layer of a lining of a pipeline, thickening of an outer arc layer of a bent pipe and the like, at present, the wear-resistant pipe of the lining is used for small-diameter pipelines (the drift diameter is less than 800 mm), wear-resistant protection is carried out on large-diameter pipelines (the drift diameter is more than 800 mm) by adhering a wear-resistant plate, and the device generally comprises a steel outer pipe, an adhesive and a wear-resistant rectangular flat plate or a rectangular arc plate. The lining wear-resistant pipe is used as a wear-resistant layer of the pipeline, is a mature and effective pipeline protection mode, and is widely applied to enterprise production. At the present stage, no matter what kind of wear-resistant materials can not produce the whole pipe fitting with the large diameter, so the pipeline with the large diameter must be protected by pasting the wear-resistant plate, the currently used rectangular flat plate or rectangular arc plate is pasted and fixed on the inner wall of the steel pipe to serve as a wear-resistant layer, the stagger joint of the wear-resistant lining plate perpendicular to the flow direction of the medium is a straight line, and the interlocking performance between the wear-resistant lining plates is poor. In the long-time operation process, the problem that the pipeline is easy to fall off exists in the mode, so that the wear-resisting protection effect of the pipeline is lost, and the pipeline is worn through in a short time. This has several serious consequences: firstly, the leakage of the pipeline wearing medium damages the surrounding environment and causes local environmental pollution; secondly, the dropping of the wear-resisting plate can cause medium blockage in the pipeline, and the normal operation can not be carried out, thereby causing severe production accidents such as shutdown and the like; thirdly, the industrial production time is wasted, and the production efficiency and the economic benefit of enterprises are reduced; fourthly, the labor intensity of production workers and maintenance workers is increased, and the risk of safe production is increased; fifthly, a great deal of wear-resistant materials are wasted, the material purchasing cost of enterprises is increased, and the profit of the enterprises is reduced.
