Wear-resistant reinforced reducer joint

Abstract

The invention discloses a wear-resistant reinforced reducer joint, which comprises a reducer joint body. The top of the reducer joint body is provided with an inner wire, the bottom of the reducer joint body is provided with an outer wire, a passage axially penetrates through the middle of the reducer joint body, the top of the passage is provided with an inner sleeve, a connecting slot is formedbetween the inner sleeve and the inner wire, a plurality of first pressure arms are arranged on the top of the outer surface of the reducer joint body and are rotatably connected to the reducer jointbody by torsion springs, and the free ends of the first pressure arms are provided with first pressure heads; the middle part of the outer surface of the reducer joint body is provided with a plurality of second pressure arms, the second pressure arms are rotatably connected with the reducer joint body through torsion springs, the free ends of the second pressure arms are provided second pressureheads, the first pressure arms applies pressure to the top of the reducer joint body, and the second pressure arms applies pressure to the bottom of the reducer joint body. The wear-resistant reinforced reducer joint has good wear resistance, is unlikely to loose, and has good structural stability.

Description

technical field [0001] The invention belongs to the technical field of reducing joints, and in particular relates to a wear-resistant and reinforced reducing joint. Background technique [0002] Reducer joints are generally processed by cutting and forging hexagonal rods. There are many types of threads used. It is an internal and external threaded pipe fitting that connects two pipes with different diameters. It plays an irreplaceable role in pipe connection. [0003] The variable diameter joint is a kind of part, which is widely used in domestic large-scale power station supporting projects, seawater, steam, cold water, hot water, oxygen, drinking water, refrigeration, oil, gas, medical gas sewage treatment projects, municipal engineering, chemical industry, oil refining, metallurgy , chemical fertilizer, paper making, medicine and other industries. Reducing joints are used when the diameter of the water pipe needs to be reduced. The threaded connection can be easily con...

Problems solved by technology

[0004] At present, due to the fact that one end of the reducing joint in the prior art is an inner thread, the internal wear is serious, and due to the structural characteristics of the threaded connection itself, it will loosen to varying degrees after a long time, so the reducing joint Stability needs to be improved
