Description

TECHNICAL FIELD

[0001] The utility model relates to the field of plug technology, especially to a high-temperature-resistant threaded hole protection plug. BACKGROUND

[0002] The high-temperature-resistant threaded hole protection plug is a device for protecting threaded holes from high-temperature environments. The protection plug adopts a conical design, making it easy to insert and remove from the threaded hole and forming a good seal inside the hole. Some have special sealing structures or sealing washers to enhance sealing performance and prevent external substances from entering the threaded hole. Some plugs are also designed for easy disassembly, and the bolted plugs can be fixed by screwing the bolts into the corresponding screw holes and applying appropriate torque, making them easy to install and replace.

[0003] The design of the protection plug makes it difficult to install and remove. After the conical plug is inserted into the threaded hole, it will be tightly stuck in the hole due to interference fit or material expansion under high temperature, making it difficult to remove. If the plug is installed too loosely, it will fall off under high-temperature vibration, failing to provide protection. The existing technology sets a clamp structure between the protection plug and the component with the threaded hole. By loosening or tightening the bolts on the clamp, the clamp can be opened or tightened, allowing the protection plug to be quickly installed and removed. This structure avoids the need for multiple rotations of the traditional threaded connection, saving time. Even if the material expands slightly under high temperature, the elasticity of the clamp can adapt to the size change, making it easy to disassemble. However, in actual use, the clamp is used in a high-temperature environment for a long time, and the components of the fastening bolts may become loose due to thermal expansion and oxidation, affecting the fastening effect of the clamp and the convenience of disassembly. Moreover, the clamping force of the clamp on the protection plug changes under high temperature, and if the clamping force is insufficient, the plug may shift, affecting the protection effect.
