Description
Technical Field
The invention belongs to the technical field of pipeline connection, and particularly relates to a compensator.
Background
The pipeline compensator mainly solves the problem of expansion with heat and contraction with cold of the pipeline caused by temperature change, eliminates the internal stress of the pipeline and enables a pipe network to keep good working conditions. At present, the compensation mode of the pipeline compensator mainly has three modes: the compensation is natural compensation, the metal corrugated pipe compensation and the sleeve compensator compensation.
The three compensation modes have certain defects. The natural compensation means that in the installation process of the steam pipeline, a U-shaped bend, a Z-shaped bend or an L-shaped bend is arranged on the straight pipeline at certain intervals, and the cold and hot compensation of the pipeline is realized by utilizing the elastic deformation of the pipeline. The advantages are that: the steam-proof pipe is durable, is not easy to leak steam and has high pressure bearing capacity; the disadvantages are that: large occupied space, large investment and small compensation amount. The metal corrugated pipe compensation is that a section of metal corrugated pipe is arranged on a straight section pipeline of a steam pipeline at certain intervals, and the metal corrugated pipe compensation has the advantages that: the occupied space is small, and no steam leaks in the fatigue range; the disadvantages are that: the pressure-bearing capacity is low, and because the temperature fluctuation of most steam pipelines is large, the expansion and contraction times of the pipelines are many, the fatigue of the corrugated pipe is easily caused by frequent actions, and the service life of the corrugated pipe is greatly reduced. The sleeve compensator has the advantages of compensation: the compensation amount is large, the occupied space is small, and the pressure bearing capacity is high; the disadvantages are that: the steam-leakage-free steam turbine is not maintainable, is easy to leak steam during use, has large maintenance workload and is rarely used at present.
For example, chinese patent CN101876386A discloses a rotary compensator for heat supply network pipelines, which includes an inner tube, an outer tube and a connecting tube connected to the outer tube, wherein graphite filler is installed between the inner tube and the outer tube, a protruding ring is installed at one end of the graphite filler facing the connecting tube, and a pressing flange bolted to the outer tube is installed at the other end of the graphite filler. Although the technical scheme uses secondary sealing, certain sealing performance is improved, the sealing device is limited to a pipeline of a high-temperature medium, certain limitation is realized, the problem of inflexibility of compensation still exists, and the compensation amount of the compensator is limited and needs to be expanded.
