Description

Nonmetal compensator

Technical Field

The invention relates to the technical field of power equipment, in particular to a nonmetal compensator.

Background

The utility boiler is one of the three current power generation devices, changes along with the thought of energy conservation and environmental protection, and under the positive conditions of the environmental protection technical progress, the power generation cost reduction and the increase of the demand, the flue gas emission of the utility boiler needs to be subjected to desulfurization and denitrification and dedusting treatment and can be directly discharged after reaching the national emission standard.

Pipeline among the prior art is high because of the flue gas temperature when carrying, during the transport, the shrinkage leads to pipeline to warp to pipeline's the expend with heat and contract with cold, especially pipeline's connection if connect firmly, warp to leak behind the certain degree under expend with heat and contract with cold's effect, for this reason, install nonmetal compensator additional at each pipeline's link, the effectual deformation amount that forms of expend with heat and contract with cold that absorbs the flue gas to pipeline production, absorb the displacement, reduce pipeline's deformation, can ensure pipeline's normal operating, can satisfy the requirement of leakproofness simultaneously again.

The nonmetal compensator in the prior art can not be adjusted in the radial multidimensional direction, has great limitation in application, and in practical application, the compensator can not provide enough multidimensional compensation and is damaged because the compensator is usually displaced due to weak vibration, settlement, thermal expansion and cold contraction of a power station boiler.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a nonmetal compensator, a compensator body is combined by a ring body and a compensation assembly, a covering is arranged between the two ring bodies for connection, the covering wraps the space between the two ring bodies, the two ends of the covering are bent and then are attached to the side surfaces of the ring bodies and are pressed tightly by the annular pressing plates, then the covering is fixed by a plurality of bolt assemblies, the two ring bodies and the covering are connected into a whole, a plurality of lug plates with through holes are uniformly distributed on the outer circumferences of the pressing plates at the two sides, the two ends of the adjusting bolt are respectively connected with the through holes of the lug plates corresponding to the positions of the two pressing plates, the invention can compensate the multidimensional direction, effectively compensate and eliminate the installation error, has high applicable temperature range and good corrosion resistance, and effectively isolates the vibration and reduces the noise.

In order to achieve the purpose, the technical scheme of the invention is as follows: a nonmetal compensator comprises a compensator body, wherein the compensator body is formed by combining two ring bodies and a compensation assembly;
