Problems solved by technology
[0003] The three-dimensional pipeline compensators installed in existing power plants and cement plants are generally designed for flue gas or pulverized coal pipelines. The structure of the three-dimensional pipeline compensator is relatively complicated, and it is inconvenient to manufacture and install. Leakage is prone to occur in five to five years, and the compensator must be replaced, resulting in a short service life of the compensator, a large workload for maintenance and replacement, and high costs

Embodiment Construction
[0016] Such as figure 1 As shown in the figure, the three-dimensional spherical pipeline compensator includes casing I1 and casing II8 which are independent of each other and have the same diameter. The spherical ring I7 and the outer surface of one end of the casing II8 are welded with a spherical ring II9, and the spherical ring I7 and the spherical ring II9 are sleeved in the outer casing 4, and the two ends of the outer casing 4 are respectively provided with fixed rings 2 . The outer surfaces of the spherical ring Ⅰ7 and the spherical ring Ⅱ9 are all set as arc-shaped spherical surfaces, and sealing rings are respectively provided between the spherical ring Ⅰ7, the spherical ring Ⅱ9 and the outer shell 4; the casing Ⅰ1 and the casing Ⅱ8 are separated by a certain distance. There is a gap, so that the sleeve I1 and the sleeve II8 can perform a certain bending movement or mutual rotation.
[0017] In this embodiment, the middle positions of the spherical ring I7 and the sp...

The invention relates to a three-dimensional sphere pipe compensator which comprises a sleeve I and a sleeve II, the sleeve I and the sleeve II are independent and have equal diameter, a spherical ring I is arranged on the outer surface of the sleeve I, a spherical ring II is arranged on the outer surface of the sleeve II, the spherical rings I and II are sheathed in an outer shell, fixed rings are arranged at two ends of the outer shell, the outer surfaces of the spherical rings I and II are both of arc-shaped spheres, and O-shaped seal rings are arranged between the spherical rings I and II and the outer shell; and a clearance is arranged between the sleeves I and II, so that the sleeves I and II can conduct certain mutual bending movement or mutual rotation. Compared with the prior art, the sphere pipe compensator is formed by the outer shell, the spherical rings, the fixed rings and the O-shaped rings, the deflection angle displacement of the compensator is large, the axial displacement of the compensator is large, and large displacement of pipe equipment, generated in running, can be effectively compensated and absorbed. The three-dimensional sphere pipe compensator is simple, convenient and practical in structure, and convenient to manufacture, install and maintain.
Description
technical field [0001] The invention relates to a pipeline compensation device, in particular to a three-dimensional spherical pipeline compensator which can realize mutual bending motion and mutual rotation between pipelines. Background technique [0002] At present, industries such as electric power, building materials, and heat generally need to install and use three-dimensional pipeline compensators in pipelines. Three-dimensional pipeline compensators are usually composed of two spherical devices and a sleeve device. The spherical device can make radial angular displacement. The sleeve device can make axial linear displacement, and the three-dimensional pipe compensator has a large deflection angle and large axial displacement, which can effectively compensate and absorb the large displacement generated by boilers and other equipment during operation. [0003] The three-dimensional pipeline compensators installed in existing power plants and cement plants are generally ...
