Abstract

The invention discloses a pipe joint pre-compressing device, relates to the technical field of pipeline conveyance, and solves the problem that an existing joint is insufficient in pressure-bearing capacity and single in pressure-bearing mode. The pipe joint pre-compressing device comprises a shell, a limiting device group, a branch pipe I, a telescopic pipe, a branch pipe II, a left limiter, a right limiter and an outer pipeline. The branch pipe I is connected to the branch pipe II through the telescopic pipe, the outer pipeline is connected in the branch pipe II, and the branch pipe I, the telescopic pipe and the branch pipe II are located in the shell. The limiting device group comprises a limiting device I, a limiting device II, a limiting device III and a limiting device IV. The leftlimiter and the right limiter are mounted on the limiting device group. The pipe joint pre-compressing device is provided with various pressure alleviating devices, so that the circumferential and axial pressures can be controlled effectively, and therefore, the pipe joint pre-compressing device has the characteristics of being high in pressure-bearing capacity and diversified in pressure-bearingmode.

Description

technical field [0001] The invention relates to the technical field of pipeline transportation, in particular to a pipe joint pre-compression device. Background technique [0002] Pipe joints are very important and common in the daily use of pipelines, and are used in various pipeline transportation fields such as oil refining, water supply, and heat supply. With the development of technology, pipe joints no longer only have simple joint capabilities, but gradually become diversified and comprehensive. For example, a pipe joint pre-compression device described in the application number "CN201410516215.9" has a pressure release function. It can deal with a variety of pipelines with large pressure fluctuations and protect the safety of the pipelines. However, this kind of pipe joint pre-compression device still has shortcomings. Because the main pressure-bearing device is arranged in a vertical pipeline, the height of the elastic device is limited, and the pressure-bearing cap...
