Intelligent double-flow-direction compensator

Abstract

The invention discloses an intelligent double-flow-direction compensator, and relates to the technical field of pipeline compensators. The compensator comprises an inner sleeve, an outer sleeve, limiting rings, a check ring, a protecting component and a seal ring. The inner sleeve is connected with a pipeline. The outer sleeve is arranged on the periphery of the inner sleeve. The inner sleeve can freely slide in the outer sleeve when the pipeline is stretched out and drawn back. The two ends of the inner wall of the outer sleeve are provided with the limiting rings respectively. The check ring is arranged on the inner sleeve. The protecting component is arranged on the outer sleeve. The seal ring is arranged between the outer port of the outer sleeve and the inner sleeve. The seal ring is a novel flexible graphite ring made of seal material. The compensator has the advantages that the sealing requirements of any pipeline can be met; the novel synthesis material for sealing is adopted between the outer sleeve and the inner sleeve and can resist high temperature, corrosion and ageing, axial sliding can be ensured, it can be ensured that a medium in a pipe does not leak, a double-flow-direction compensation structure is adopted, a double-direction compensation effect is achieved, and the compensation amount is increased.

Description

technical field [0001] The invention relates to the technical field of pipeline compensators, in particular to an intelligent dual-flow compensator. Background technique [0002] The compensator is a compensation device for thermal fluid pipelines. It is mainly used for axial thermal expansion displacement absorption compensation after the auxiliary installation of straight pipelines. It is a compensator that is directly installed in any pipeline that transports non-corrosive fluids. It is widely used in Electric power, metallurgy, chemical industry, construction, food, pharmaceutical and other important industries of the national economy to compensate the displacement of the pipeline system due to thermal expansion and contraction. [0003] At present, there are pipeline compensators, which can complete the compensation needs of the pipeline when the medium flow direction is single, but when the heat source changes, the medium flow direction will change accordingly, and the...

Problems solved by technology

[0003] At present, there are pipeline compensators, which can complete the compensation needs of the pipeline when the medium flow direction is single, but when the heat source changes, the medium flow direction will change accordingly, and the impact pressure of the medium on the metal bellows will increase exponentially, resulting in compensation. The fatigue life of the device is reduced, and it cannot even be used anymore
