Description

Technical Field

[0001] The utility model belongs to the field of chemical compensators, and particularly relates to a compensator composite joint. Background Art

[0002] A chemical compensator is an elastic element used at pipeline joints. It is mainly used to absorb different degrees of deformation caused by expansion, contraction, vibration, dislocation, etc. at pipeline joints, and to protect pipelines. Compensators are widely used in pipeline systems in various industries such as petroleum, chemical, metallurgy, and electric power. In the chemical field, since pipeline systems are often affected by multiple factors such as temperature, pressure, and medium, they are prone to deformation and displacement. The use of compensators can effectively solve these problems, ensure the normal operation of pipelines, and avoid dangerous situations such as leakage and rupture, thereby ensuring the safety and reliability of chemical production.

[0003] According to a Chinese patent with the announcement number "CN216952189U", a pipe column telescopic compensator is disclosed, including a connecting pipe, a sealing joint is provided at the top of the connecting pipe, a threaded pipe is provided at the bottom of the sealing joint, the threaded pipe is threadedly connected with the connecting pipe, a plurality of sealing rings are provided on the inner side of the sealing joint from top to bottom, a telescopic pipe is provided in the middle of the sealing joint, and the telescopic pipe and the connecting pipe are connected together by a screw rod. The utility model solves the problem that the existing bellows telescopic compensator is inconvenient to use due to the hardness of the bellows during adjustment, which makes the adjustment of the bellows telescopic compensator time-consuming and laborious, and affects the normal use of the telescopic compensator. By improving and optimizing the structure of the telescopic compensator, the bellows structure is removed from the telescopic compensator, which is convenient for the telescopic compensator to be telescopically adjusted, so that the staff can easily screw the nut when adjusting the compensator;

[0004] It can be seen from the above structure that when the above compensator is installed and fixed to the pipeline, the flange and the flange hole are used to facilitate the cooperation with the external pipeline, so as to facilitate the connection of the connecting pipe and the telescopic pipe with the external pipeline, and facilitate the installation and disassembly of the telescopic compensator. Although the flange method can achieve an effective fixing method, when connecting through the flange, it is necessary to carry multiple screws and nuts for cooperation and installation, which makes the installation of the compensator very troublesome. At the same time, according to the figure and text, it can be seen that the connecting joint has only a single flange and flange hole, which leads to poor sealing after the installation is completed.
