Problems solved by technology
The traditional connection method between the pipeline and the compensator is to use the flange to connect directly, so it is difficult to seal the gap between the pipeline and the compensator, which will easily lead to water or air leakage at the connection, which will bring certain problems to the project.

Embodiment 1
[0011] like figure 1 As shown, the pipeline compensator of this embodiment includes a main body 1 and connecting ends 2 at both ends of the main body 1, a flange 3 is provided on the connecting end 2, and a tapered pipe 4 is provided on the outer side of the connecting end 2 of the flange 3, and The outer surface of the tapered tube 4 is provided with an elastic sealing layer 5 .
[0012] When connecting the pipeline compensator and the pipeline, first insert the conical tube 4 of the pipeline compensator connection end 2 into the pipeline, and then use the flange 3 to fasten the pipeline compensator connection end 2 and the pipeline together, because The tapered tube 4 increases the contact area between the connecting end 2 of the pipeline compensator and the pipeline, thus effectively improving the sealing performance and reliability.

The invention aims at providing a pipeline compensator which is good and reliable in sealing performance. The pipeline compensator comprises a body and two connecting ends respectively arranged at the two ends of the body, wherein each connecting end is provided with a flange; and the pipeline compensator is characterized in that a tapered pipe is arranged at the outer side of the flange of each connecting end. When the pipeline compensator is connected with a pipeline, the tapered pipes arranged at the connecting ends of the pipeline compensator are firstly inserted into the pipeline, then the connecting ends of the pipeline compensator are firmly fixed on the pipeline by the flanges, and the contact area between the connecting ends of the pipeline compensator and the pipeline can be enlarged by the tapered pipes, so that the sealing performance is effectively improved and the reliability is improved.
Description
technical field [0001] The invention relates to a pipeline compensator. Background technique [0002] In heating, in order to prevent the pipe from being deformed or damaged due to thermal elongation or temperature stress when the heating pipe is heated up, it is necessary to install a compensator on the pipe to compensate for the thermal elongation of the pipe, thereby reducing the stress and stress on the pipe wall. The force acting on the valve member or bracket structure. The traditional connection method between the pipeline and the compensator is to use the flange to connect directly, so it is difficult to seal the gap between the pipeline and the compensator, which will easily lead to water or air leakage at the connection, which will bring certain problems to the project. Security risks. Contents of the invention [0003] The object of the present invention is to provide a pipeline compensator with good sealing performance and reliability. [0004] T...
