Example Embodiment

[0010] The present invention will be further described in detail below in conjunction with the drawings.

[0011] As shown in Figure 1 and Figure 2, a method for producing a pipeline compensator includes a circular collar body 2 with a circular groove 1, and a sealing ring 3 is provided in the circular groove 1. The collar body 2 is composed of a first arc-shaped compression ring 4 and a second arc-shaped compression ring 5; in this embodiment, the compensator is installed in the pipeline, so that the two seal rings in the circular groove are used. The end telescopic tube performs axial displacement and angular displacement to absorb the deformation in multiple directions. Among them, the self-tightening force and medium force of the sealing ring are used for sealing to improve the sealing performance and avoid leakage.

[0012] The first arc-shaped pressing ring 4 and the second arc-shaped pressing ring 5 are respectively provided with an upper connecting seat 6 and a lower connec...

Abstract

The invention provides a production method of a pipeline compensator comprising a circular lantern ring body with a circular groove which is internally provided with a sealing ring. The circular lantern ring body is composed of a first circular arc chuck ring and a second circular arc chuck ring. According to the production method provided by the invention, the self-tightening force of the rubbersealing ring and medium pressure are used for sealing, and the sealing performance is good; the leakage of media is prevented, and the service life of the compensator is prolonged effectively; and themaintenance cost of a pipeline is reduced. In addition, the pipeline compensator is compact and rational in structure and wide in application scope, and can meet the compensation requirements of pulverized coal pipelines of large power station boilers and other multidimensional deformation compensation requirements.

Description

technical field [0001] The invention relates to the technical field of pipeline compensators, in particular to a production method of pipeline compensators. Background technique [0002] At present, the existing pipeline compensator uses asbestos rope and graphite to press the bolt gland. This sealing form has no elasticity in the actual use process. Once the pipeline vibrates, leakage will occur after long-term use, reducing the The service life of the compensator is shortened, and the maintenance cost of the pipeline is increased. Contents of the invention [0003] The object of the present invention is to provide a boiler pulverized coal Vickers pipeline compensator with compact and reasonable structure, good sealing performance and wide application range. [0004] In order to solve the problems existing in the background technology, the present invention adopts the following technical solutions: a production method of a pipeline compensator, comprising a circular coll...
