Description

Technical Field

[0001] This utility model relates to the field of rotary joint technology, specifically to a flow-dividing rotary joint with adjustable flow distribution. Background Technology

[0002] A flow-diverting rotary joint is a type of rotary joint used to distribute fluid from one input source to multiple output ports. It has one or more fluid inlets for receiving fluids from the outside, such as liquids and gases. These fluids enter the interior of the rotary joint through the inlets. When the rotating part of the rotary joint rotates relative to the stationary part, the internal channels and sealing structure ensure that the fluid does not leak during the rotation.

[0003] Existing diversion rotary joints still have the following problems when in use: because they are sealed internally by a single layer of sealing rings, they may leak after long-term use due to wear, aging, corrosion or impurities. In addition, some diversion rotary joints may not be able to allow one or more connectors to work independently. The working status of all output ports can only be synchronized, which makes it impossible to meet the actual needs in some application scenarios that require flexible control of fluid distribution, thus limiting the working mode and efficiency of the equipment.
