Problems solved by technology

However, the various technical measures for improving the wear resistance of the arcuate part of the elbow that is impacted and worn by the fluid still have some deficiencies, such as poor wear resistance, high cost, and troublesome manufacture, so there are still some deficiencies. room for improvement

Embodiment 1

[0012] Embodiment 1: Referring to the accompanying drawings, the right-angle elbow 5 of the lined pipeline is used as the outer mold, and the inner cavity is painted with Kemlok (brand CF218) adhesive, and the inner hole is fixed with a combination of a semicircle and a semiellipse (or an ellipse). ) The outer surface is coated with a release agent such as the lining mandrel 7 of a silane release agent, and the mandrel 7 has two sections 7.1 and 7.2 in the axial direction to form, and is positioned by the positioning boss 8 (also can be positioned by other positioning methods). There are caps 1.1 and 1.2 on the two ends of the elbow respectively, which are positioned and connected with the mandrel 7 through the bolt 3. The capping function is to form a lining layer baffle; provide help. There is a protruding positioning ring cover edge 10 on the outer periphery of the cover 1, which forms a positioning with the elbow flange. The edge of the cover is provided with a demoulding...

Abstract

This invention relates to a wear-resistant liner pipeline elbow and forming method which can prolong it life time characterizing in thickening inside of pipeline elbow bow part of wear-resistant liner to turn thinner and thinner steadily towards the two sides and fixing noncircle axial combined core and enabling to increase the bow part inside gap steadily in the bend inside hole to form liner layer in gaps of unequal width faces between inside of liner elbow and the core mode formed by filling or pressing especially by urethane rubber to pour the liner to increase the wear resistance of the easiest worn out part of the elbow.

Description

[0001] Technical field Jiang Longfu Tan Xiping [0002] The invention relates to a pipe elbow with wear-resistant lining and a forming method that can significantly improve the service life of the pipe elbow. Background technique [0003] Conveying wear-resistant pipes with high solid content such as power plant coal ash, coal slurry, mine tailings, flue gas wet desulfurization, dust removal and sewage, etc., the elbow is impacted and worn by the fluid. The high-speed motion changes the direction to cause the greatest scouring force on this part, resulting in impact wear, especially when conveying fluids containing solid-phase materials, this kind of wear is even more severe, so the arcuate part of the elbow is more likely to wear than the straight pipe wall, and the service life is usually only 1 / 5 of the straight pipe part affects the service life of the entire pipeline. The pipeline wear-resistant elbow disclosed in Chinese patent 93247971 and 00235090 is to make the arc o...
