Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The invention discloses a compensator for pipelines, such as figure 1 As shown: it includes an outer sleeve 11 and a core barrel 12, the outer sleeve 11 and the core barrel 12 are connected through a compensation device; one end of the core barrel 12 is interference fit with one end of the outer sleeve 11, presenting an interference fit The "back" shape structure; the compensation device is installed between the two ends of the interference fit; in order to ensure that the compensation device occupies a small space and has a large pressure bearing capacity, the compensation device in this embodiment includes a sliding device 1, a sealing packing 2 and a sealing ring; the sliding device...

Abstract

The invention provides a compensator for a pipeline. An outer sleeve and a core barrel are connected through a compensation device. One end of the core barrel is in interference fit with one end of the outer sleeve in a concentric-square shape. The compensation device is installed between the two ends which are in interference fit with each other. Sliding devices are installed at the end, arranged in an interference fit mode, of the core barrel and / or the outer sleeve. Sealing fillers are arranged on one sliding device and / or between the two sliding devices. Sealing rings are fixed to the inner sides of the sliding devices. The sealing fillers are composed of a plurality of spherical sealing fillers, and the spherical sealing fillers are composed of a plurality of fine-pore-diameter sealing filler bodies with the particle size being 0.04-0.08 mm. According to the compensator for the pipeline, the sealing fillers are made of graphite fillers, the particle size is 0.04-0.08 mm, and very high compressibility is achieved; and when axial extruding and radial extruding are conducted at the same time, the sliding devices carry out moving compensation, and the fillers can conduct compression and extension along with moving of the sliding devices.

Description

technical field [0001] The invention relates to the technical field of pipeline compensators, in particular to a pipeline compensator. Background technique [0002] The pipeline compensator is mainly to solve the problem of thermal expansion and contraction of the pipeline caused by temperature changes, eliminate the internal stress of the pipeline, and keep the pipeline network in good working condition. At present, there are mainly three forms of compensation for steam pipeline compensators: one is natural compensation, the other is metal bellows compensation, and the third is sleeve compensator compensation. There are certain deficiencies in the above three compensation methods. Natural compensation means that during the installation of steam pipelines, a "U" bend, "Z" bend, or "L" bend is set at regular intervals on the straight section of the pipeline, and the elastic deformation of the pipeline is used to realize the smoothness of the pipeline. Heat and cold compensa...
