High-pressure elbow

Abstract

The invention discloses a high-pressure elbow. Guide impellers are arranged on an inner wall of the elbow; multiple levels of guide impellers are arranged in the medium flow direction of the elbow uniformly at intervals, and in any level of guide impellers, and multiple groups of guide impellers are arranged in the radial direction of the elbow uniformly at intervals; the radial size of each guide impeller in the elbow is 1 / 4-1 / 3 of that of the elbow; blades are made of impact-resistant metal materials; the uniform spaced distance of the multiple levels of guide impellers in the medium flow direction is 1-3 times the radial size of the elbow; the uniform spaced distance of the multiple levels of guide impellers in the radial direction of the elbow is 1 / 4-1 / 2 of the outer peripheral arc length of the elbow; a thickened wear resisting layer is arranged on the peripheral side of the elbow. The guide impellers are arranged in the elbow, orderly dredge high-pressure fluid media, bear a part of stress of flushing of the high-pressure fluid media and facilitate uniform circulation of the media; besides, the thickened wear resisting layer is additionally arranged on the peripheral side of the elbow, and the service life of the elbow is further prolonged.

Description

technical field [0001] The invention belongs to the technical field of high-pressure pipe fittings, and in particular relates to a high-pressure elbow. Background technique [0002] As a pipe fitting and a pipe connection, the elbow is used to change the flow direction of the pipeline conveying medium; the elbow is the place where the circulating medium turns, and it is the weak link of the entire pipeline; specifically, the inner wall of the elbow is subjected to the concentration of stress, and at the same time The outer peripheral side of the elbow is susceptible to wear due to the application environment; thus accidents such as perforation, leakage and cracking are prone to occur under the erosion and damage of the high-pressure fluid medium, so there are serious safety hazards. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a high-pressure elbow with a simple structure, which can reduce th...
