Wear-resistant pipeline compensator for electric power

Abstract

The invention provides a wear-resistant pipeline compensator for electric power. The wear-resistant pipeline compensator for electric power comprises a compensator body, wherein the compensator body comprises a compensation pipe, a plurality of corrugated segments are arranged in the middle of the compensation pipe, a mounting ring is welded to the position, close to one opening, of the inner wallof the compensation pipe, a protective cover is arranged at the top of the mounting ring, and a wear-resistant pad is arranged at the top of the mounting ring. The mounting ring is directly welded tothe inner wall of the compensation pipe to provide positions for mounting the protective cover and the wear pad. The mounting ring, the protective cover and the wear-resistant pad are directly detachably fixed. After the protective cover and the wear-resistant pad are damaged, replacement can be carried out, and the pipeline compensator can be prevented from being directly replaced. The wear-resistant pad can achieve a protective effect on the mounting ring. Slag enters the compensation pipe from one end provided with the wear-resistant pad and makes direct contact with the wear-resistant pad, so that the mounting ring can be protected, and long service life of the mounting ring is ensured.

Description

technical field [0001] The invention relates to the field of pipeline compensators, in particular to a wear-resistant pipeline compensator for electric power. Background technique [0002] Pipeline compensators, also known as expanders or expansion joints, expansion joints, are mainly used to compensate for thermal expansion and contraction of pipelines caused by temperature changes. If the pipe is not completely free to expand or contract when the temperature changes, thermal stresses will develop in the pipe. This stress must be considered in the pipeline design, otherwise it may cause the rupture of the pipeline and affect the normal production. As an important part of pipeline engineering, compensators play an important role in ensuring the long-term normal operation of pipelines. [0003] There are many types of pipeline compensators, which are divided into axial type, transverse type, angular type and pressure balance type according to the compensation type; the axia...

Problems solved by technology

[0004] In the electric power industry, it is necessary to use fuel to generate electricity. After the fuel is used, slag is formed. The discharge of slag also needs to use pipelines. In order to ensure the safe operation of pipelines, bellows compensators are often installed in pipelines to absorb or compensate pipeline Axial displacement, because the slag produced by the fuel is high temperature and solid particles, it is easy to damage the corrugated part of the pipeline compensator and cause rupture. The existing solution technology is to shield and protect the corrugated part by welding the protective tube on the inner wall of the pipeline compensator , to avoid being directly worn by the slag, but the protective tube is directly in contact with the slag, so the service life of the protective tube is low. At the same time, it is a welded structure with the pipeline compensator, so it only ensures that the service life of the pipeline compensator is partially improved, and cannot be effectively solved. This phenomenon, when the protective tube is worn out, will still cause damage to the pipeline compensator for replacement
