Description

Technical Field

[0001] The utility model relates to the technical field of pipeline compensators, in particular to a corrosion-resistant thermal pipeline compensator. Background Art

[0002] The main function of a thermal pipe compensator is to eliminate the heat generated by the pipe and the impact it has on the pipe. It can offset thermal stress and use the effective expansion and contraction of its working body, the bellows, to absorb the dimensional changes caused by thermal expansion and contraction in the pipe. It can also be used to reduce noise and vibration. For example, as shown in a corrosion-resistant thermal pipe compensator with Chinese patent application number CN202221475640.4, a number of equidistant connecting ears are symmetrically fixed on the first connecting sleeve and the second connecting sleeve, and the same threaded connecting rod is fixed between the two symmetrical connecting ears by nuts. Using the connecting ears to fix the threaded connecting rod is equivalent to fixing the distance between the two first connecting flanges, preventing excessive thermal expansion, which would cause the corrugated thermal pipe body to exceed the bearing range and be damaged.

[0003] However, due to the lack of a guiding mechanism, it cannot automatically move according to the ambient temperature, resulting in offset during expansion and contraction, which reduces the working efficiency of the compensator and makes it difficult to support the middle part of the compensator after the pipeline expands, causing the middle part of the compensator to sag, which can easily lead to pipeline rupture. Utility Model Content

[0004] In order to solve the problem raised in the above background technology that the lack of a guiding mechanism makes it impossible to automatically move according to the ambient temperature, resulting in deviation during expansion and contraction, which reduces the working efficiency of the compensator and makes it difficult to support the middle part of the compensator after the pipeline is expanded, thereby causing the middle part of the compensator to sag and easily lead to pipeline rupture, the utility model provides the following technical solutions:

[0005] A corrosion-resistant thermal pipe compensator includes a thermal pipe compensator body for connecting two thermal pipes. Flanges for connecting the thermal pipes are provided at the upper and lower ends of the thermal pipe compensator body. A guide device guide assembly for guiding and supporting the thermal pipe compensator body is provided on the outer side of the flange, and there are three guide device guide assemblies.

[0006] The guiding device guide assembly includes a mounting assembly arranged on the lower flange, a support assembly for guiding and supporting the thermal pipe compensator body is arranged above the mounting assembly, and a guide assembly for guiding the support assembly is arranged in the box cavity of the mounting assembly.

[0007] Furthermore, a mounting plate is fixedly mounted on the disc body of the upper flange, and there are three mounting plates, which are distributed in a circular array on the disc body of the upper flange.

[0008] Furthermore, a fixing plate is fixedly installed on the disk body of the lower flange, and there are three fixing plates, which are distributed in a circular array on the disk body of the lower flange.

[0009] Furthermore, the support assembly includes a bolt rod passing through the mounting plate, the rod body of the bolt rod is threadedly connected to a nut for locking the bolt rod in cooperation with the mounting plate, and the bottom end of the nut is fixedly mounted with a guide rod for inserting into the mounting assembly.

[0010] Furthermore, the installation assembly includes an installation box fixedly installed on the top of the fixed plate, and the left and right ends of the installation box are provided with sliding grooves for allowing the guide assembly to move up and down.

[0011] Furthermore, the guide assembly includes a movable plate fixedly mounted on the bottom end of the guide rod, with sliders for sliding in the slide groove fixedly mounted on the left and right ends of the movable plate, and a spring for resetting the movable plate is provided below the movable plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By setting up a guiding device, when the thermal pipe compensator body expands and contracts according to the different thermal expansion and contraction changes of the thermal pipe, the movable plate on the bottom end of the guide rod and the elastic action of the spring, while the sliders on the left and right ends of the movable plate slide in the slide groove, the movable plate can be expanded and contracted in the installation box to prevent the thermal pipe compensator body from deflecting when expanding and contracting according to the different thermal expansion and contraction changes of the thermal pipe, thereby ensuring the adjustment effect; and it can support the middle part of the compensator after the pipe expands, thereby preventing the pipe from rupturing.
