Example Embodiment

[0027] Example 1

[0028] Pipe rotation restraint device, which is mainly composed of baffle 1, concave arc insert 2, convex arc insert 3 and T-beam 4. The concave arc insert 2 is inserted into the baffle 1 by the expansion process, and the convex arc The insert is clamped into the T-beam 4 by the expansion joint process. One end of the T-beam 4 is fastened to the pipe 6 by the clamp 5, and the convex arc insert 3 at the other end is placed in the arc groove of the concave arc insert 2, convex The convex arc surface of the arc insert block 3 and the concave arc surface of the concave arc insert block 2 are both concentric cylindrical surfaces centered on the pipe center, and the convex and concave arc surfaces coincide. The baffle 1 is fastened to the ground or wall by using bolts or welding. The baffle 1, the concave arc insert 2, the convex arc insert 3, the T-beam 4 and the clamp 5 are all made of stainless steel. Both the convex arc insert 3 and the concave arc insert 2 ar...

Abstract

The invention belongs to the field of pipe limiting, and discloses a pipe rotation limiting device. The pipe rotation limiting device is mainly composed of a baffle (1), a concave arc insert (2), a convex arc insert (3) and a T-type beam (4), wherein the concave arc insert (2) is clamped into the baffle (1) through adoption of an expansion connection technology, the convex arc insert is clamped into the T-type beam (4) through the adoption of the expansion connection technology, one end of the T-type beam (4) is fastened with a pipe (6) through a clamping hoop (5), the convex arc insert (3) at the other end of the T-type beam (4) is placed in an arc chute formed in the concave arc insert (2), a convex arc face of the convex arc insert (3) and a concave arc face of the concave arc insert (2) are both concentric cylinder faces with the pipe center as the circle centers, and the convex arc face is matched with the concave arc face. The pipe rotation limiting device is a device which directly limits the pipe rotation without limiting the pipe translational motion.

Description

technical field [0001] The invention belongs to the technical field of pipeline restraint, and in particular relates to a pipeline rotation restraint device. Background technique [0002] The piping system of a large reactor is often very large. The pipeline is tens of meters long and hundreds or even thousands of millimeters in diameter. It often spans several workshops and connects important equipment such as main pumps and heat exchangers. It must bear the combined effects of temperature, pressure, vibration and other loads. The stress analysis of the pipeline system is to reasonably configure supports and hangers on the pipeline to limit the displacement of the pipeline so that the stress meets the relevant requirements of the code. [0003] In three-dimensional space, piping nodes have six degrees of freedom, namely three linear displacements and three angular displacements. So far, the pipe supports and hangers used in engineering, except that the fixed frame restric...
