Problems solved by technology

However, in the process of pipeline prefabrication, due to the existence of machining errors and continuous accumulation, it is inevitable that there will be a deviation in the size of the pipeline at a certain pipeline connection. The length of the two sections of the pipeline is longer or shorter than the design size, which will lead to the failure of the normal connection
In this case, the pipeline can only be reconstructed on site, which will affect the construction progress and construction quality

Abstract

The invention discloses a vacuum pipeline length compensation device which comprises a pipe connector, a concave flange and a compensator flange. Annular grooves surrounding central through holes are formed on end faces of opposite sides of the concave flange and the compensator flange. The end face of the other side of the concave flange is connected with a pipeline. Sealing gaskets are arranged in the annular groove of the concave flange and the annular groove of the compensator flange. A flange is welded at one end of the pipe connector, and the other end of the pipe connector extends into the central through hole of the compensator flange. One end of a sleeve is arranged outside the pipe connector in a sleeved mode and is inserted into the annular groove of the compensator flange. The other end of the sleeve is inserted into the annular groove of the concave flange. The two ends of the sleeve both compress the sealing gaskets in the annular grooves. Bolts respectively penetrate through an installation hole of the concave flange and an installation hole, corresponding to the installation hole of the concave flange, of the compensator flange and are fastened by nuts. The vacuum pipeline length compensation device solves the problem of installation difficulty caused by connecting pipe length changes due to pipeline processing errors at technological pipeline installation time so as to ensure the sealing requirements of connecting positions.

Description

technical field [0001] The invention belongs to a pipeline length compensation device, in particular to a vacuum pipeline length compensation device. Background technique [0002] In the construction of vacuum pipelines, the construction can be carried out after the pipelines are prefabricated in advance, which can greatly improve the construction speed and construction quality. However, in the process of pipeline prefabrication, due to the existence of machining errors and continuous accumulation, it is inevitable that there will be a deviation in the size of the pipeline at a certain pipeline connection. In this case, the pipeline can only be reconstructed on site, which will affect the construction progress and construction quality. Contents of the invention [0003] The present invention is proposed in order to overcome the shortcomings in the prior art, and its purpose is to provide a vacuum pipeline length compensation device. [0004] Technical scheme of the prese...
