Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of damping, more specifically, the utility model relates to a damping assembly of combined pipeline compensator. BACKGROUND

[0002] In industrial pipeline systems, due to factors such as medium flow, temperature change or mechanical vibration, the pipeline is prone to vibration and displacement, which may cause problems such as leakage at the connection, fatigue damage of the pipeline, etc. The pipeline compensator is an important component for compensating for pipeline displacement and absorbing vibration, and the damping assembly as a key component directly affects the performance of the compensator and the safety of the pipeline system.

[0003] In the prior art, the damping assembly structure of some pipeline compensators has deficiencies. For example, some damping structures only rely on springs for damping, and the springs are prone to repeated oscillation during the compression and rebound process, resulting in poor damping effect, and frequent vibration may cause the sealing structure to fail, causing leakage problems. At the same time, the traditional sealing structure is mostly single sealing, and the sealing performance is limited, and it is difficult to maintain the sealing effect stably for a long time in a high-pressure or complex vibration environment. In addition, the connection and rotation between the components of some damping assemblies are not flexible enough during installation, increasing the installation difficulty and affecting the installation efficiency and accuracy.

[0004] Therefore, how to design a combined pipeline compensator damping assembly that can effectively dampen, improve sealing performance, and be easy to install has become a problem that needs to be solved by those skilled in the art. The utility model provides a new damping assembly of combined pipeline compensator to solve the problems existing in the prior art through the synergistic effect of the damper and the spring, the double sealing structure and the flexible installation design.

[0007] The compensating pipe is rotatably connected with a plug disc at both ends, and each plug disc is sleeved with a spring on the inner side.

[0008] The two connecting heads are connected through the damper and the two rotating discs, are supported by the two springs, are symmetrically arranged at two ends of the compensation pipe, are slidably connected with the inner wall of the connecting head through the plug disc, can slide relative to the compensation pipe while keeping sealing, and thus leakage is avoided; when the pipeline shakes, the spring is compressed and then rebounds, the spring slowly rebounds through the damper, repeated shaking is avoided, and thus the damping effect is achieved, leakage caused by multiple frequency vibrations is avoided, the compensation of the pipeline is ensured, and the sealing effect is improved.

[0009] Preferably, a shaft sleeve is connected between the rotating disc and the connecting head.

[0010] Preferably, the connecting head comprises a connecting pipe and a blocking disc, a threaded groove is formed in the inner wall of one end of the connecting pipe, and a hole blocking disc is coaxially arranged at the other end of the connecting pipe.

[0013] Preferably, a bolt hole is formed in the rotating disc, bolt rods are arranged at two ends of the damper, and the bolt rods are inserted into the corresponding bolt holes and connected with the nuts.

[0014] The technical effects and advantages of the utility model are as follows:

[0015] 1. When the pipeline vibrates, the spring is compressed to store energy, and the damper slows down the rebound speed when rebounding, so that repeated vibration is inhibited, the vibration frequency is effectively reduced, and the damping effect is improved.
