Description

Technical Field

[0001] The utility model relates to the technical field of rotary joint installation tools, in particular to a rotary joint hole card installation tool. Background Art

[0002] Annealing furnaces are common equipment in metal processing workshops. If the annealing furnace's rotary joint leaks on the on-site production line, it is necessary to remove the copper rotary joint at the back of the annealing furnace, and then replace the wear-resistant water-sealing ceramic parts and wave springs on the fixed shaft of the annealing furnace for maintenance, so that the water in the pipeline will not leak when passing through the rotary joint.

[0003] After the repair is complete, installing the hole card of the rotary joint is more difficult because there are one or more corrugated springs inside the rotary joint, which require a lot of force to install. In the past, one person needed to use circlip pliers to clamp the hole card and place it in the rotary joint, while another person used a hammer to hit the end of the rotary joint. The hammer should use appropriate force during the striking process. If the force is too strong, it will damage the wear-resistant water-sealing ceramic parts; if the force is too weak, the rebound force of the corrugated springs will cause the hole card of the rotary joint to be installed improperly, which can easily lead to serious water leakage in the rotary joint. Utility Model Content
