The three-dimensional spherical compensator is composed of two spherical construction elements and a sleeve construction element. The spherical structural element is subject to angular displacement of radial deflection, and the sleeve structural element is subject to axial linear displacement. The spherical construction element and sleeve construction element of the compensator can be independently installed. When the device is independent, the spherical construction element can handle the pipeline bending compensation, and the sleeve construction element can handle the pipeline axial expansion compensation.
When two spherical construction elements and a sleeve construction element are combined, an elbow joint structure that can simultaneously absorb three-dimensional shrinkage is formed.
The three-dimensional spherical compensator has large deflection angle, large axial displacement and can effectively absorb the large downward displacement of the boiler.
When the three-dimensional spherical compensator is selected, such as the degree device, it mainly absorbs the downward displacement of the boiler, that is, the angular displacement of the three-dimensional spherical compensator. At this time, the three-dimensional spherical compensator with large angular compensation and small axial displacement should be selected. On the contrary, the vertical device mainly absorbs the downward displacement of the boiler; That is, three-dimensional spherical compensation for axial displacement. At this time, three-dimensional spherical compensator with small angular compensation and large axial displacement should be selected.
The preparation specification of three-dimensional spherical compensator is DN200~DN600, totally 9 kinds; The preparation specifications are as follows: 18 ", 20", 22 ", 24", 26 ", 28", 30 "32" in English; According to the length, the preparation specifications are: 1200~3000, 5 kinds in total; The total specifications are 85.
