technical field:
The utility model relates to the transporting elbow parts of the industries such as a kind of building, mine, metallurgy, electric power, oil, coal, grain processing, and particularly a kind of two points of double layer wear resistant and impact resistant bend pipe special double-layers are curved greatly.
background technique:
The forming technique of bend pipe mainly contains casting, compression molding etc., and they are all rely on shaping die, is generated by cast or hot cold-press process profiling; No matter be any machinery equipment and pipeline, major part all uses bend pipe, mainly in order to carry various material; The material of bend pipe has the materials such as cast iron, stainless steel, alloyed steel, malleable cast iron, carbon steel, non-ferrous metal and plastics; In the industries such as building, mine, metallurgy, electric power, oil, coal, grain processing, the conveying of material is carried by pipeline pressure, delivery pipe is subject to larger pressure and serious wearing and tearing, therefore to delivery pipe, particularly bridge piece has higher combination property requirement, improve the working life of bend pipe, now become the difficult problem being difficult to capture.
Bend pipe is the most widely used is at present individual layer Technique of High Magnesium Bend Pipe, also has the double-deck rich chromium cast iron bend pipe of a small amount of use.Individual layer Technique of High Magnesium Bend Pipe wear-resisting property is poor, and hardness is low, and Security is low; Double-layer wear-resistant bend pipe cost is high, and quality is better, and wear-resisting property is excellent, and hardness is high, and Security is high, but cost performance is not high.Develop a kind of excellent performance, cost is low, Security is good abrasion-proof bent tube is the work of whole industry in the urgent need to carrying out, under grasping the mechanism of pipe wear and different operating state, the type of flow of material, simulate the region that pipeline is the most easy to wear, and can to this region, improve wearing layer thickness or improve the wear-resisting property of this region material, to reach the overall object improving the bend pipe life-span, for client is cost-saving, for society economizes on resources; Each constituent elements of two points of double layer wear resistant and impact resistant bend pipes is extremely important.
summary of the invention:
The purpose of this utility model is to overcome the low shortcoming of the large curved wear resistance of prior art bend pipe, provides a kind of two points of double layer wear resistant and impact resistant bend pipe special double-layers curved greatly.
The utility model adopts following structure and parts to realize its goal of the invention: a kind of two points of double layer wear resistant and impact resistant bend pipe special double-layers are curved greatly, and it is made up of with large curved interior abrasion-proof bent tube 2 large curved outer protection bend pipe 1; Large curved interior abrasion-proof bent tube 2 agrees with that to be arranged on large curved outer protection bend pipe 1 inner.
The utility model even can not damage by external force collision impact distortion in transportation, installation and use process because of bend pipe to protect the wearing layer of bend pipe internal layer; and cause being out of shape because being subject to materials inside impact force the function even damaged; be provided with large curved outer protection bend pipe 1; and being provided with conjunction surface 3 in large curved outer protection bend pipe in large curved outer protection bend pipe 1 inside, in large curved outer protection bend pipe, conjunction surface 3 is large curved outer protection bend pipe 1 inner headed face.
The utility model, in order to increase the function of the wear resistance in large curved neutral position, is provided with large curved interior abrasion-proof bent tube 2; And the outer conjunction surface 4 of large curved interior abrasion-proof bent tube is provided with in large curved interior abrasion-proof bent tube 2 outside; The outer conjunction surface 4 of large curved interior abrasion-proof bent tube is large curved interior abrasion-proof bent tube 2 periphery; Wherein large curved interior abrasion-proof bent tube 2 is designed to from ends A thickening thickening to middle D with both sides C to middle B, ensure that the high wear resistance in large curved neutral position.
Owing to have employed the technical combinations scheme of above structure and parts, the utility model achieves its goal of the invention preferably, these two points of double layer wear resistant and impact resistant bend pipe special double-layers are curved is greatly designed to double-deck unique texture, be divided into protective layer and wearing layer, protective layer protection wearing layer can not because of bend pipe in transportation, installation and use process by external force collision, impact and be out of shape and even damage, and be subject to materials inside impact force and cause being out of shape and even damage; Wearing layer pipe thickness uneven distribution (thickening thickening to middle D with both sides C to middle B from ends A), more serious position of wearing and tearing, wall thickness is the thickest, thus improves bend pipe working life curved greatly, realizes the uniformity in whole bent wear position life-span; Internal layer wearing layer can adopt the high-abrasive materials such as rich chromium cast iron, low-chromium cast-iron, medium chrome cast iron, pottery, Bearing Steel, cemented carbide, alloyed steel, macromolecular material, wear resistance electrode, and the wear resistance of bend pipe can be made to improve several times; Outer protective layer adopts the material such as low alloy steel or middle low carbon steel; Such design at least can make bend pipe overall weight alleviate more than 10%, reaches the object reducing costs, save material, economize on resources; Also easily realize producing in enormous quantities, steady quality is reliable, and Security is high.
