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 double-deck large curved wear resistant and impact resistant bend pipe is extremely important.
summary of the invention:
The purpose of this utility model is to overcome the low shortcoming of the wear resistance of large curved existence in bend pipe in prior art, and gradually thick bilayer is curved greatly to provide a kind of double-deck large curved supporting side of wear resistant and impact resistant bend pipe.
The utility model adopts following structure and parts to realize its goal of the invention: gradually thick bilayer is curved greatly in a kind of double-deck large curved supporting side of wear resistant and impact resistant bend pipe, 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 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 wear-resisting property in large curved neutral position, is provided with large curved interior abrasion-proof bent tube 2, and is provided with the outer conjunction surface 4 of large curved interior abrasion-proof bent tube 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 A end thickening gradually to middle B point, C end is constant to middle B dot thickness, ensure that the high wear resistance in large curved neutral position, wherein A end is that side that double-deck large curved wear resistant and impact resistant bend pipe is the thinnest, B point is in the middle part of double-deck large curved wear resistant and impact resistant bend pipe, and C end is that side that double-deck large curved wear resistant and impact resistant bend pipe is the thickest.
Owing to have employed the technical combinations scheme of above structure and parts, the utility model achieves its goal of the invention preferably, the large curved supporting side of wear resistant and impact resistant bend pipe of this bilayer is the curved greatly unique texture being designed to bilayer of thick bilayer gradually, be divided into protective layer and wearing layer, protective layer protection wearing layer can not because bend pipe be in transport, install and collide by external force in using process, impact and distortion even damages, and cause distortion even to damage because being subject to materials inside impact, wearing layer pipe thickness uneven distribution is (thickening gradually to middle B point from A end, C end is constant to middle B dot thickness), to wear and tear more serious position, wall thickness is the thickest, thus improve bend pipe working life curved greatly, realize the uniformity in whole bent wear position life-span, internal layer wearing layer can adopt rich chromium cast iron, low-chromium cast-iron, medium chrome cast iron, pottery, cemented carbide, Bearing Steel, alloyed steel, macromolecular material, the high-abrasive materials such as wearing layer are made in wear resistance electrode built-up welding, 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.
