Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0034] Such as figure 2 As shown, the expansion joint 10 of the pipeline compensator according to the embodiment of the present invention, wherein the expansion joint 10 includes a plurality of material layers 1 made of a flexible material, and the plurality of material layers 1 are superimposed on each other to be integrated and can be arbitrarily Adjacent material layers are bonded together without gaps.

[0035] The multiple material layers 1 of the expansion joint 10 can bond adjacent material layers to each other by means of bonding, vulcanization or hot pressing, so that there is no gap between the material layers and the bonding is tight. A plurality o...

Abstract

The invention discloses an expansion joint (10) of a pipeline compensator, which comprises a plurality of material layers (1) made of flexible materials. The material layers (1) are stacked on each other to be integrated, and the adjacent material layers are adhered together without gaps. The invention further discloses the pipeline compensator and a method for manufacturing the expansion joint of the pipeline compensator. The expansion joint is high in structural strength, and accordingly is high in reliability.

Description

technical field [0001] The invention relates to pipeline connections in the industrial field, in particular to an expansion joint of a pipeline compensator, a manufacturing method thereof, and a pipeline compensator. Background technique [0002] In the industrial field, especially in the pipeline system, it is often necessary to set a non-metallic compensator at the joint of the pipeline to compensate for the relative displacement between the two pipelines due to fluid flow, the deformation caused by the expansion of the fluid in the pipeline, and the equipment Vibration generated by operation, etc. Especially in the flue gas system of desulfurization technology, the outlet flue of the absorption tower is generally equipped with a non-metallic compensator, which is mainly used to compensate the displacement of the desulfurization clean flue due to the thermal expansion and contraction of the flue gas, and has the function of absorbing The deformation and vibration of the p...
