The utility model relates to pipeline
engineering technical field, concretely is a kind of heat preservation
elbow pipe with anti-seismic structure, including
elbow pipe body, heat preservation mechanism and anti-seismic mechanism, the heat preservation mechanism and anti-seismic mechanism fixedly connected in the outer surface of
elbow pipe body, the inner wall of elbow pipe body is equipped with flow guide groove, the heat preservation mechanism includes internal heat preservation layer and external heat preservation component, the anti-seismic mechanism includes anti-seismic inner layer and external anti-seismic component.In the utility model, through the setting of anti-seismic inner layer, buffer spring and
shock absorber, form multilevel anti-seismic
system, anti-seismic inner layer can preliminarily absorb the vibration energy of elbow pipe body, avoid
vibration transmission to heat preservation layer, buffer spring can buffer external
impact, buffer the
impact force in the inside of elbow pipe body, prevent the rupture of elbow pipe body due to local stress too large,
shock absorber and shock-absorbing expansion spring synergistic effect, the vibration generated due to
external connection is quickly attenuated, effectively avoid pipeline interface loose, weld
cracking and other risks.
