Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation pipelines, and more specifically, to a flange-connected heat preservation pipeline assembly. Background Art

[0002] A heat preservation pipeline is a conveying pipeline with heat preservation materials provided on its outer layer. It generally connects the pipelines together through fixing parts such as flange plates and bolts. However, in actual use, there are still some drawbacks. For example, when connecting the pipelines using flange plates and bolts, although the stability of the pipeline connection can be ensured, during the long-term use of the heat preservation pipe, the ends of the bolts used to connect the flange plates are exposed to the air for a long time, and their surfaces are easily affected by the environment and rust, which will cause the overall bolts to become loose, and gaps will appear at the flange plates, resulting in leakage at the pipeline connection, and further affecting the normal use of the heat preservation pipe. Summary of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a flange-connected heat preservation pipeline assembly to solve the problem that the ends of the bolts at the flange used for connecting pipelines in the prior art are easily corroded by the environment.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: A flange-connected heat preservation pipeline assembly includes a main heat preservation pipe body, and the flange-connected heat preservation pipeline assembly further includes

[0005] A connecting flange, which is arranged at one end of the main heat preservation pipe body in the length direction;

[0006] A fastening bolt, which is detachably installed on the surface of the connecting flange;

[0007] An installation groove, which is opened on the periphery of the connecting flange;

[0008] A connecting seat, which is arranged in a hollow structure. A torsion spring is fixedly connected inside the connecting seat. One end of the torsion spring is fixedly connected with a connecting column. A limiting ring is arranged on the surface of the connecting column, and the surface of the limiting ring is rotationally connected with the inner wall of the connecting seat;

[0009] A socket cover, which is fixedly connected to one end of the connecting column opposite to the torsion spring in the length direction. The socket cover is arranged in a hollow structure, and the inner wall of the socket cover is sleeved with the end of the fastening bolt.

[0010] Wherein, it further includes a spacer gasket and a sealing gasket. The spacer gasket is fixedly installed on one side of the socket cover opposite to the connecting seat, and the surface of the spacer gasket is attached to one side of the connecting flange in the length direction. The sealing gasket is arranged on the surface of the connecting flange opposite to the surface of the spacer gasket.

[0011] Among them, an auxiliary component is further included, and the auxiliary component is arranged on the periphery of the connecting flange.

[0012] Among them, the auxiliary component includes a fixing plate, a connecting shaft, a turning plate, a receiving groove, a spring, and a connecting frame. The fixing plate is fixedly installed inside the installation groove. The connecting shaft is rotatably installed on the surface of the fixing plate. The turning plate is fixedly installed on the surface of the connecting shaft. The receiving groove is opened inside the turning plate. One end of the spring is fixedly connected to the inside of the receiving groove. The other end of the spring is fixedly connected to the inside of the connecting frame. The surface of the connecting frame fits with the inside of the receiving groove. The bottom of the connecting frame is fixedly connected to the surface of the connecting seat.

[0013] The beneficial effects of the above technical solution of the present utility model are as follows:

[0014] In the above solution, after connecting the main body of the heat-insulating pipe through the connecting flange and the fastening bolt, the socket cover is sleeved on the end of the fastening bolt. Since a groove adapted to the shape of the end of the fastening bolt is opened inside the socket cover, the socket cover and the fastening bolt can be closely fitted, and with the cooperation of the sealing gasket, the end of the fastening bolt can be isolated from the external environment. In addition, through the provided torsion spring, a certain acting force can be provided to the connecting column, and the direction of the acting force is the same as the tightening direction of the fastening bolt, so as to play a certain fixing role on the fastening bolt. Therefore, not only the sealing and protection of the fastening bolt are realized, and its end is prevented from rusting due to environmental factors, which further affects the stability. In addition, after the fastening bolt is installed, the socket cover is driven by the torsion spring to assist in tightening the fastening bolt, which can further ensure the stability after the fastening bolt is installed, so as to avoid leakage at the pipe connection and ensure the normal use of the heat-insulating pipe;

[0015] By turning the turning plate around the connecting shaft, the connecting frame and the corresponding components such as the connecting seat can be turned away from the installation position of the fastening bolt, so as to avoid the components such as the connecting seat from hindering the installation of the fastening bolt. In addition, through the spring, a tightening effect can be achieved, so that the socket cover and the fastening bolt are more closely sleeved, further improving the practicability of the device.
