Abstract

The invention is suitable for the field of rotary joints, and provides a rotary joint suitable for high-speed-change rotation and frequent start-stop working conditions, the rotary joint suitable for high-speed-change rotation and frequent start-stop working conditions comprises a fixed end shell, a rotary core shaft and a fastening assembly, one side of the fixed end shell is connected with a channel pipe, and one side of the channel pipe is connected with an elbow pipe; the rotary core shaft is arranged in the fixed end shell, and a rotary connecting assembly is arranged between the rotary core shaft and the fixed end shell; and the fastening assembly is arranged in the channel pipe. When the rotary joint suitable for the high-speed-change rotation and frequent start-stop working conditions is used, the rotary core shaft is arranged in the fixed end shell and the channel pipe, at the moment, the fixed end shell and the rotary core shaft are preliminarily connected through the rotary connecting assembly, and then the fastening assembly is driven to operate; and thus the fastening assembly connects the rotary core shaft with the channel pipe, so that the rotary core shaft is connected and fixed, and the rotation of the rotary core shaft is not hindered.

Description

technical field [0001] The invention belongs to the field of rotary joints, and in particular relates to a rotary joint suitable for high variable speed rotation and frequent start-stop working conditions. Background technique [0002] Rotary joints refer to pipeline connection devices, and the connected pipelines can be rotated relative to each other, and can be used to transmit various media such as gas, liquid and oil. The rotary joint is a closed rotary connector that rotates 360° to convey the medium. The application fields of the rotary joint cover almost all processing and manufacturing industries, such as: metallurgy, machine tools, power generation, petroleum, rubber, plastics, textiles, printing and dyeing, pharmaceuticals, cigarettes, papermaking , food, feed processing, etc.; rotary joints can be divided into: hydraulic rotary joints, high-pressure rotary joints, multi-channel rotary joints, high-speed rotary joints, high-temperature rotary joints, single-channel...
