Embodiment Construction

[0031] A non-metallic compensator, including a flange 1, a ring plate 2, an inner sleeve I 6, an inner sleeve II 8, an inner sleeve cover plate 15 and a non-metallic composite layer 10, the non-metallic composite layer 10 is fixed by bolts 20 On the ring plate 2, the inner sleeve I6 and the inner sleeve II8 are welded on the ring plate 2, and the two ends of the inner sleeve cover plate 15 are respectively welded on the inner sleeve I6 and the inner sleeve II8.

[0032] Casting material 7 capable of withstanding a high temperature of 1200°C is poured between the inner sleeve I 6 , the inner sleeve II 8 and the cover plate 15 to form the heat insulation layer of the compensator.

[0033] The space formed by the non-metallic composite layer 10, the ring plates 2 at both ends and the inner sleeve 16 is filled with a high-temperature-resistant heat-insulating material 4, forming the thermal insulation layer of the compensator.

[0034] The thermal insulation material 4 is a high-t...

Abstract

The invention relates to a nonmetal compensator of a pipeline, in particular to a nonmetal compensator of high sealing and high temperature resistance. The nonmetal compensator comprises a flange, annular plates, an inner sleeve I, an inner sleeve II, an inner sleeve cover plate and nonmetal compound layers, wherein the nonmetal compound layers are fixed on the annular plates by bolts; the inner sleeve I and the inner sleeve II are welded on the annular plates; both ends of each inner sleeve cover plate are respectively welded on the inner sleeve I and the inner sleeve II; casting materials are cast among the inner sleeve I, the inner sleeve II and the inner sleeve cover plates to form a heat insulating layer of the compensator; and heat insulating materials with high temperature resistance are filled in a space formed by the nonmetal compound layers, the annular plates on both ends and the inner sleeve I as a temperature keeping layer of the compensator. The nonmetal compensator can adapt to severe alternating high temperature of 100 DEG C to 1200 DEG C, has a water cooling pipe coil, has larger compensation quantity on the axial displacement and the radial displacement of the pipeline and also has high sealing performance and good practicality in a primary smoke gas pipeline system of a converter.

Description

technical field [0001] The invention relates to a pipeline non-metal compensator, in particular to a high-tight high-temperature-resistant non-metal compensator. Background technique [0002] The compensator is a device used to absorb the axial and radial displacement of the pipeline system due to thermal expansion and contraction or other reasons, and is widely used in important industries such as electric power, metallurgy, chemical industry, construction, food, and pharmaceuticals. [0003] For the flue gas exhaust pipe of the primary high-temperature flue gas of the converter and the conveying pipe of similar high-temperature medium, the compensator must have the performance of high temperature resistance, as well as the performance of large axial and radial compensation; at the same time, the primary flue gas of the converter contains a large amount of The flammable and toxic gas carbon monoxide requires the compensator to have a high degree of sealing; the temperature ...
