AI Technical Summary

Technical Problem

In converters, due to space constraints, when the installation direction of the air duct is at an angle to the axial direction of its end opening, the sealing strips rub against each other during installation, resulting in a decrease in sealing performance.

Method used

The flip-sealing structure is adopted so that when the first object and the second object are at an angle to the first direction, the first object moves along the second direction and the second object rotates around the first axis, forming a gap first and then connecting, and forming a seal using an elastic sealing element.

Benefits of technology

It avoids wear of the sealing strips during installation, improves sealing performance, and improves airflow delivery and the compactness of the internal structure of the equipment through the airflow guide and increased airflow area.

Abstract

The utility model discloses a kind of turnover sealing structure, wind tube assembly and current transformer, the turnover sealing structure is used to make first object, second object mutually butt joint in the first direction of first opening, second opening, at least one of first opening, second opening is equipped with elastic sealing element, it includes: first object is suitable for moving along with the second direction perpendicular to first direction;Second object is suitable for rotating around the first axis of third direction perpendicular to first direction, second direction;Before first object is installed in place, second object rotates and is parked in first position, to make first opening, second opening form interval in the first direction;After first object is installed in place, second object rotates and is parked in second position, to make first opening, second opening mutually butt joint and press against elastic sealing element to form seal. Adopt the turnover sealing structure, wind tube will not rub mutually when installing, can improve sealing element strip wear condition, improve sealing performance.
