Description

Technical Field

[0001] The utility model relates to the field of compensators, in particular to a compression type compensator. Background Art

[0002] Compensators are also commonly called expansion joints, or telescopic joints. They are composed of bellows and end pipes, brackets, flanges, ducts and other accessories that constitute their working body. They are a type of compensation element that utilizes the effective expansion and contraction of the bellows, the working body, to absorb dimensional changes in pipelines, ducts, containers, etc. caused by thermal expansion and contraction, or to compensate for axial, lateral and angular displacements of pipelines, ducts, containers, etc. It can also be used to reduce noise and vibration.

[0003] There are still certain deficiencies in the use of the existing technology for the compression type compensator. The supporting mechanism on the commonly used compression type compensator is usually reinforced by screw support. Since the two ends of the screw are fixed with nuts, the fixed position has no anti-deformation ability. As the bellows changes, the fixed position will become loose or broken, reducing the service life of the support mechanism. Utility Model Content

[0004] The purpose of the utility model is to provide a compression compensator to solve the problem that the supporting mechanism on the commonly used compression compensator proposed in the above background technology is usually supported and reinforced by screws. Since the two ends of the screw are fixed with nuts, the fixed position has no anti-deformation ability. As the bellows changes, the fixed position will become loose or broken, reducing the service life of the supporting mechanism.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a compression compensator, comprising a compression compensator body, a bellows is provided in the middle of the compression compensator body, compression assembly ports are provided at both ends of the compression compensator body, a reinforcement layer is provided on the surface of the compression compensator body at both ends of the bellows, fixing ears are provided on both sides of the reinforcement layer, a guide strut is provided inside the fixing ears, spring fixing seats are provided at positions at both ends of both sides of the compression compensator body aligned with the fixing ears, a spring is provided inside the spring fixing seat, a screw is provided at the upper end of the spring, and a combined connecting block is provided at the lower end of the spring.

[0006] In a further embodiment, the number of the guide struts and the number of the springs are three, the guide struts and the springs are connected via a combined connecting block, and the guide struts and the combined connecting block are connected via plugging.

[0007] In a further embodiment, the guide support rod is fixedly connected to the fixing ear via a first fixing nut.

[0008] In a further embodiment, the spring fixing seat is connected to the compression compensator body by welding, and two sides of the spring fixing seat are configured as hollow structures.

[0009] In a further embodiment, the spring is connected to the spring fixing seat via a screw rod, and the screw rod and the spring fixing seat are fixedly connected via a second fixing nut.

[0010] In a further embodiment, a convex groove is provided inside the compression assembly port, a sealing ring is provided inside the convex groove, and the sealing ring is connected to the convex groove by gluing.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, both ends of the guide strut are connected to the spring, which can buffer, support and reduce shock for the guide strut. When both ends of the guide strut are deformed under the action of external force, the spring can restore the guide strut to its original state after the external force is removed, so that both ends of the guide strut have good anti-deformation ability, avoiding the guide strut from affecting the firmness of the fixed position when it is active, extending the service life of the guide strut, and arranging the spring inside the spring fixing seat, which can increase the firmness of the spring installation and limit the range of activity of the spring.
