Abstract
The utility model discloses a kind of interior complete, two points of double layer wear resistant and impact resistant bend pipe Special wear-resistant bend pipes, it makes large curved interior abrasion-proof bent tube by mould; And the outer conjunction surface of large curved interior abrasion-proof bent tube and the large curved installation conjunction surface of flange is provided with in large curved interior abrasion-proof bent tube outside; The wearing layer complete in this, two points of double layer wear resistant and impact resistant bend pipe Special wear-resistant bend pipes are exactly large curved inside, wearing layer pipe thickness uneven distribution (thickening thickening to middle D with both sides C to middle B from ends A), improve the working life that bend pipe is curved greatly, internal layer wearing layer can adopt high-abrasive material, makes the wear resistance of bend pipe improve several times; 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.
Description
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, particularly a kind of interior complete, two points of double layer wear resistant and impact resistant bend pipe Special wear-resistant bend pipes.
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, and 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 interior complete 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 the shortcoming being to overcome prior art existence, provides wear-resisting, shock proof interior complete, two points of double layer wear resistant and impact resistant bend pipe Special wear-resistant bend pipes of a kind of low cost of manufacture, high life.
The utility model adopts following structure and parts to realize its goal of the invention: complete, two points of double layer wear resistant and impact resistant bend pipe Special wear-resistant bend pipes in a kind of, and it makes large curved interior abrasion-proof bent tube 1 by mould; And the outer conjunction surface 2 of large curved interior abrasion-proof bent tube and the large curved installation conjunction surface 3 of flange is provided with in large curved interior abrasion-proof bent tube 1 outside; The outer conjunction surface 2 of large curved interior abrasion-proof bent tube is large curved interior abrasion-proof bent tube 1 periphery, and the large curved installation conjunction surface 3 of flange is located at large curved interior abrasion-proof bent tube 1 two ends; Wherein large curved interior abrasion-proof bent tube 1 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 member, the utility model achieves its goal of the invention preferably, the wearing layer complete in this, two points of double layer wear resistant and impact resistant bend pipe Special wear-resistant bend pipes are exactly large curved inside, wearing layer pipe thickness uneven distribution (thickening thickening to middle D with both sides C to middle B from ends A), to wear and tear more serious position, 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 material such as rich chromium cast iron, low-chromium cast-iron, medium chrome cast iron, pottery, cemented carbide, Bearing Steel, alloyed steel, macromolecular material, wear resistance electrode built-up welding, makes the wear resistance of bend pipe improve several times; 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.
