Online replaceable wear-resisting elbow

Abstract

The invention relates to an online replaceable wear-resisting elbow. The online replaceable wear-resisting elbow comprises an elbow body. The elbow body is internally provided with an inside liner layer. The elbow body is further provided with a protection device. The protection device is composed of outer arc steel and a wear-resisting layer. The outer arc steel is provided with screw holes A. The wear-resisting layer comprises a second sealing layer, a first sealing layer and a contact layer. The upper middle portion of the second sealing layer is provided with an arc-shaped groove A. The lower portion of the second sealing layer is provided with a first sealing layer. The middle portion of the first sealing layer is provided with an arc-shaped groove B. The lower portion of the first sealing layer is provided with the contact layer. The lower portion of the contact layer and the inside liner layer form a smooth arc. The outer side faces of a fixed seat is provided with connecting racks. The inner side face of the fixed seat is provided with a rubber sealing strip. The upper portion of the fixed seat is provided with screw holes B. The sides, close to the fixed seat, of the connecting racks are provided with connecting arms. The connecting arms are provided with screw holes C. The tail ends of the connecting arms are provided with sealing bars. The middle portions of the connecting racks are further provided with adjusting bolts. The online replaceable wear-resisting elbow has the advantages of being convenient to replace, long in service life and low in replacement cost.

Description

technical field [0001] The invention relates to the technical field of pipe elbows, in particular to a wear-resistant elbow that can be replaced online. Background technique [0002] The wear and tear of industrial elbows has always been a factor affecting safe and civilized production. With the continuous development of science and technology, materials have also continued to innovate, and materials such as cast stone, cast steel, alloys, and centrifugally cast composite ceramics have appeared one after another; in the slurry pipeline system, The elbow is a vulnerable part, and the damaged part often appears at the outer arc, because the flow direction of the slurry changes when it passes through the elbow, and it directly washes the outer arc of the elbow. At present, there are many wear-resistant elbows that increase the overall thickness of the wear-resistant material at the outer arc. , so as to increase the service life of the elbow. At that time, it will still be dama...

[0002] The wear and tear of industrial elbows has always been a factor affecting safe and civilized production. With the continuous development of science and technology, materials have also continued to innovate, and materials such as cast stone, cast steel, alloys, and centrifugally cast composite ceramics have appeared one after another; in the slurry pipeline system, The elbow is a vulnerable part, and the damaged part often appears at the outer arc, because the flow direction of the slurry changes when it passes through the elbow, and it directly washes the outer arc of the elbow. At present, there are many wear-resistant elbows that increase the overall thickness of the wear-resistant material at the outer arc. , so as to increase the service life of the elbow. At that time, it will still be damaged after long-term use. , Long service life, low replacement cost wear-resistant elbow that can be replaced online is very necessary
