Abstract
The utility model discloses a universal steel-plastic expansion joint which comprises a steel main body and gland bushes arranged at the two ends. The expansion joint is characterized in that a low-density polyethylene layer lining is arranged in the steel main body; gasket rings are arranged at the inner side of the jointed end of the steel main body, which is jointed with the two gland bushes; and the gasket rings are in bevel contact with the steel main body. The universal steel-plastic expansion joint is reasonable in structure and the inner wall of the joint is smooth and free, so the damage to the joint by water is small, the corrosion resistance is good and the sealing performance is good. Therefore, the expansion joint is an ideal first-aid repair accessory for water supply enterprises.
