Abstract

The invention discloses a spring assembly with a limiting device. The spring assembly includes the limiting device, a spring, a bearing member and a casing. The spring is arranged inside the casing, and the bottom end of the spring is fixedly connected to the bottom of the casing; the limiting device is arranged at the top end of the spring and includes a limiting baffle at the top end of the spring and a limiting structure fixed on the outer side of the casing, the limiting structure is arranged above the limiting baffle, and the distance from the lower surface of the limiting structure to the bottom of the spring is smaller than the free length of the spring; one end of the bearing member is connected to the limiting baffle, and the other end of the bearing member is connected to a to-be-supported object; within the limit range, the spring assembly can be used as the spring; beyond of the limit range, the spring assembly can be used as a rigid bearing body, it is ensured that pipelines are free of too large deformation when the load is suddenly changed, and therefore the conditions that the working conditions of the process pipelines are too many, the load is discontinuous underdifferent working conditions, and the changes are large are avoided; and the requirements for the working conditions and discontinuous thermal displacement changes are met, and the operation stabilityand reliability of an overall pipe system are ensured.

Description

technical field [0001] The invention belongs to the technical field of process pipeline design, and in particular relates to a spring assembly with a limiting device. Background technique [0002] The selection of springs is the main content of the design of various types of steam, water, molten salt, heat transfer oil and other process pipeline supports and hangers in the industrial field, which is related to the stability and safety of the installation and operation of the entire piping system. However, for pipelines with many operating conditions and large load changes under different working conditions, the use of existing springs cannot meet the actual needs. For molten salt pipelines, the pipeline sinks significantly under full load conditions. The deformation is large, but after the load is unloaded, the pipe will quickly return to the free state, and at the same time, with the force of the spring, the pipe will deform severely or even rupture. Contents of the inven...
