Features of high-pressure self-sealing rotary compensator
Self-sealing rotary compensators for pipelines are widely used in the fields of petroleum, petrochemicals, steel, electric power, and central heating.
Compared with traditional compensation methods, this compensator has the advantages of long compensation distance, good safety, small pressure drop, long service life, etc., and can reduce carbon dioxide and sulfur dioxide emissions.
The high-pressure resistant self-sealing rotary compensator consists of a sealing seat, a rotating cylinder, a compression spring, bolts and nuts, sealing packing, a sealing gland, a fastening flange, etc. The fastening flange, spring, packing gland and outer sleeve flange are tightened with bolts, and a rotation centering and rolling device is provided between the rotating inner pipe and the seal seat. The axial compression of the slidable packing gland flange and the relatively stationary packing and seal seat is achieved by a pre-tensioned connection of evenly distributed compression springs and adjustable screws on the end of the packing gland seal seat. When the functional movement of the rotating inner tube naturally causes normal wear of the packing, under the elastic action of the compression spring, the packing gland always maintains a certain pressing force on the packing, automatically compensates for the wear amount of the packing in time, and maintains the stability of the packing relative to the mating parts. seal. The precision machining of the inner and outer tubes and the setting of the centering rolling device ensure a high concentricity of the product, so that the wear of the filler during functional operation of the inner tube is minimal and even, which is conducive to automatic compensation or adjustment of sealing of the structure, and also has It is conducive to the relative movement of the inner and outer tubes, and the friction resistance is relatively small.
