Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0009] Such as figure 1 As shown, the new pipeline flexible joint includes a flexible body 1, a flange body 2 arranged outside the flexible body 1, and a steel hoop 3 arranged outside the flange body 2, and the steel hoop 3 is semicircular , both sides of the flexible body 1 are provided with sealing rings 4; in this embodiment, due to the design of the sealing ring 4, the sealing effect between the flexible joint and the pipeline can be improved, and the two ends of the joint can be deflected appropriately, and the shaft or Lateral displacement, it has the characteristics of pressure resistance, good elasticity and large displacement.

[0010] The flexible joint is a steel joint, designed in this way, has the characteristics of temperature resistance, wear resistance, long service life, etc., and can withstand large temperature changes.

[0011] Finally, i...

Abstract

The invention relates to the technical field of flexible joints, in particular to a novel pipeline flexible joint. The novel pipeline flexible joint comprises a flexible body, a flange body and a steel hoop, wherein the flange body is arranged on the outside of the flexible body, the steel hoop is arranged on the outside of the flange body, the steel hoop is of a semi-ring shape, and seal rings are arranged on two sides of the flexible body. Two ends of the novel pipeline flexible joint can deflect to a certain extent, axial displacement and lateral displacement can be adjusted freely, and the novel pipeline flexible joint has the advantages of being pressure-resistant, good in elasticity, large in displacement, good in vibration absorption and noise reduction effect and the like. By means of the novel pipeline flexible joint, the connection of valves and pipelines can be flexibly adjusted within a certain range, physical stretching and shrinkage of the pipelines caused by the fact that the temperature of the environment changes can be adjusted freely, ground subsidence is compensated, and the pipelines can be connected with one another conveniently.

Description

technical field [0001] The invention relates to the technical field of flexible joints, in particular to a novel pipeline flexible joint. Background technique [0002] At present, flexible joints are indispensable automatic compensation equipment in pipeline systems in building materials, metallurgy, mining, petrochemical, electric power and other industries. However, the flexible joints in the prior art have complex structures, pressure difference resistance, poor elasticity, small displacement, and poor vibration absorption and noise reduction effects, so they cannot meet the actual use requirements. Contents of the invention [0003] The purpose of the present invention is to provide a new type of pipeline flexible joint with reasonable design, simple structure, temperature resistance, wear resistance, good elasticity, large displacement, good vibration absorption and noise reduction effect, and long service life. [0004] In order to solve the problems existing in the...
