AI Technical Summary

Technical Problem

Existing stainless steel rigid connectors cause significant errors in the weighing module of the cooling vessel during operation in the high-temperature vessel, failing to meet production requirements. Furthermore, rubber connectors cannot be used for connections between hot and cold vessels.

Method used

A high-temperature resistant double-helix flexible connector is designed, which uses flexible connecting pipes, flanges and transition connecting pipes, and has internal spiral metal wires and hollow pipes. It realizes the connection between high-temperature reactor and cooling reactor through flexible deformation and circulating water protection.

Benefits of technology

The weighing error has been reduced to less than 2kg, improving the accuracy of the weighing module of the cooling vessel, and is suitable for high-temperature environments of 400-450℃.

Abstract

A high-temperature resistant double-helix flexible connector relates to the field of machine connection technology. The specific solution is as follows: The high-temperature resistant double-helix flexible connector includes a flexible connecting tube, two flanges, and two transition connecting fittings. The two transition metal fittings are respectively fixedly connected to both ends of the flexible connecting tube, and the two flanges are respectively fixedly connected to the ends of the two transition metal fittings. A spirally arranged metal wire and a spirally arranged hollow pipe are fixed to the inner wall of the flexible connecting tube. The inlet and outlet of the hollow pipe are respectively located at both ends of the flexible connecting tube. Due to its flexible connection characteristics, the interference error of rigid connections is greatly reduced, making the weighing module of the cooling vessel more accurate, with an error of less than 2 kg, which is of great significance to practical production.
